[Rik]

We're looking to collect as much information on the 2700, various models, firmware, poisoning techniques, set up tips, firewall settings, understanding the logs etc as we can.

If you can contribute, please post in this thread. Thanks.

I find this site useful: http://bt2700hgv.tripod.com/ir1002700HGV.htm

It is also updated quite regularly - 5th Jan being the last time

[AlanM]

The one issue I had with this router at the start, was that I could not stop it going off to the BT servers even with the old DNS poisoning in place (?). The logs confirmed it had been talking them, and I was concerned that if it auto-updated the firmware, then there may come a time when BT issue a firmware which finally prevents anyone using this router on anything other than a BT connection.

I used Opera to edit the pages and set the router to use manually entered DNS server addresses, (which were of course useless using 10.0.0.0 for both Primary & Secondary).
I then put the proper DNS server addresses into the PC's  NIC.
All my home PC's - NIC's etc use a fixed IP address.

PC's works fine and the router can't go anywhere !

Great router for long/poor lines. Here's some of my stats:

Out of interest; would it be possible to set the router DNS to OpenDNS, then block it from accessing *.bt.com that way?

[AlanM]

Wouldn't like to say for sure but I suspect that it may not be quite as straight-forward as that. Perhaps someone else has tried this?
Now that everything is working OK, I'm reluctant to go changing things !

I can understand that. I may give it a try once I have the thing to play with.

[Sebby]

A good one, given to me by a member on this forum, is that you can get a lot of "hidden" information (statistics, etc) at http://192.168.1.254/tech.

[Rik]

You can also substitute xslt for tech.

[Lance]

And, I think, substitute it for MDC

[Rik]

Not to mention home for the IP address.

[Sebby]

You can also substitute xslt for tech.

Do you mean tech for xslt? If so that doesn't work for me - it just takes me to the normal stats page. 

[Rik]

Might be a firmware issue, then, I'm on SBC.

[Sebby]

Same here, Rik. 

[Rik]

So what happens if you use:

http://home/xslt?PAGE=J42

?

[Sebby]

Firstly, if I try and use http://home/ I get nothing anyway, but substituting home with gateway.2wire.net or 192.168.1.254, then I get to the "secret" page, yes. 

[Rik]

Weird, it works for me...

Have we spelt out DNS poisoning anywhere? If not:

For DNS poisoning: at IE browser address bar enter http://192.168.1.254/xslt?PAGE=J38 then at "Advanced-DNS Name Table"

In the DNS Name box type: cwmp.cms.smehomehubrms.bt.com

In the IP Address box type in: 10.0.0.0

Thanks to Kinmel for these two additional addresses:

pbthdm.bt.motive.com
pbthdm2.bt.motive.com

Does this work with OpenDNS enabled? I'm not sure if it blocks DNS requests if the DNS servers are changed...

[Rik]

No idea, Adam, I just know it's the basic poisoning method. I suppose it should work regardless of which DNS servers are used.

[Sebby]

That's a very useful set of links, Rik. Thanks.

[Rik]

Found and stolen in my usual style.

[Sebby]

You're so modest. 

[kinmel]

My dual SSID 2700 HGV is not DNS poisoned to let me see what happens over time.

Once per day it connects as follows:-
INF  2008-01-13T07:49:29Z  cwmd:  session started, server: 'https://pbthdm2.bt.motive.com/cwmpWeb/CPEMgt';, event code(s): '4 VALUE CHANGE,2 PERIODIC'

INF  2008-01-13T07:49:39Z  cwmd:  session completed successfully

The router continues to work perfectly with IDNet.

Does anyone have any idea what these log entries mean ?

[g7pkf]

2-wire with sbc firmware manual is HERE

hope it helps

[Rik]

Thanks, Dean. I'll tack this onto the sticky.

[g7pkf]

Rik maybe an idea to delete all posts like this one that are not full of anything useful from the sticky.

then the sticky actually gives just good links and none of the cr**.

makes reading easier for the newbie

[Rik]

I'll produce a 'clean' sticky in due course, Dean - I've just been letting it grow for a while first.

[Rik]

Thanks to Merlin for this.

I've found a way to open it easily. follow this:-

lay the router down on its side, with the front nearest to you, and the badge (2wire or BT ) to the left of you,if its to the right, turn it over.

If you've got that correct,to read the writing ,power,ethernet,wireless etc,
you should have to tilt your head to the left.

With a thin bladed knife, insert it between the black plastic light guard, and the silver surround

Now the tricky bit, gently prise the black plastic light guard towards you, until you can see two silver tags, while keeping the black plastic bit pulled forward, gently ease the silver surround upwards, until the silver tags clear the black plastic light guard. (If it will not move up, it's because you have not pulled the black plastic forward enough.)

Gently work that opening around the two sides of the router, until the whole of that side comes off

I've just read that through and it looks really complicated, but its not really, just looks it.

[Rik]

Great post, karmic, in fact.

[Glenn]

Not sure if this has been posted before, but here is a 2wire FAQ http://www.dslreports.com/faq/twowire

[Rik]

Good link, Glenn. 

Is it just me, or does DSL Reports look dataed, as a site, these days?

[Sebby]

It does, Rik.

[Jimbo]

Some info of my 2700 if it helps or not...

Assembly No:- 4201-003003-006
Hardware No:- 2701-100588-005

Interesting to me as on this link, http://bt2700hgv.tripod.com/ir1002700HGV.htm it doesn't have this combination down.   It does not list a Hardware number beginning 2701 just 2700.

Running the SBC Firmware v4.25.19.  No DNS entries required either for this to work. 

[Sebby]

Great guide, Les.

[kinmel]

Excellent guide,  Les


Thanks for that

[Rik]

Nice one, Les. 

[LesD]

In the browser's address bar I entered: http://gateway.2wire.net/management.
This brought up the Management and Diagnostic Console complete with the System Summary.

In the vertical rectangular box on the right is a menu pick-list of facilities that can be accessed.
Under Broadband Link I selected Configure and entered:

Back in the vertical rectangular box on the right, from the menu I picked Firewall and selected Advanced


Back in the vertical rectangular box on the right, next from the menu I picked Local Network and selected Wireless:

Back in the vertical rectangular box on the right, next from the menu I picked Advanced and selected DNS Resolve:

Back in the vertical rectangular box on the right, from the menu pick System Summary at the top of the box.
Make sure that under Configuration that you see:

If you want to change your MTU go back to the vertical box on the right of the System Summary page.
In this box pick Advanced and select Configure Services.

Rik or someone with the power,   

In the sections referenced above I have my rights and lefts mixed up and with copy and paste it appears a number of times.   

Please can the words "the vertical rectangular box on the right" be changed to "the vertical rectangular box on the left" all through the text.

I had just got into bed after posting and I thought did I get this wrong but could not bring myself to get out to see.

Thanks in advance.

[Sebby]

Done.

[Rik]

Thanks, Seb, I had started to reply when the forum dropped offline again.

[LesD]

  Guys.

A couple more bits of information that do appear elsewhere but just might be worth restating are these:
In the Digest I posted at post no. 35 above alternative addresses
for: http://gateway.2wire.net/management
are: http://192.168.1.254/tech and http://192.168.1.254/mdc among others.

If you fully understand what you are doing, software or firmware updates are done via access to this page: http://192.168.1.254/upgrade 

I have updated the post no. 35, converted it to a pdf file and a attached it to this post so that if anyone should want a copy of it for themselves they can open the pdf file and do a Save As to a location of their own

Karmic work, Les. 

[Glenn]

It's worth noting that the above links will only work if the router is configured without changing its default IP.

[LesD]

Karmic work, Les. 

Thanks Rik,

What would be good if someone with the Dual SSID version could take a look and see how much of I what I
have written applies to setting up the Dual SSID version as well.

Reading Alan's post no. 29 I don't think there can be that big difference so possibly with a minor alteration to my text we could cover setting up both versions in the one document.

What do you think?

[Rik]

On my To Do list.

[LesD]

It's worth noting that the above links will only work if the router is configured without changing its default IP.

Hi Glen,

I see what you mean about using the IP Address.
Is the original form: http://gateway.2wire.net/management for example more general?

[Rik]

AFAIK, Les, the numeric form specific to the configuration is what's required.

[Glenn]

Les, for a factory reset router, what you have typed is just fine. I know that some people, me included change the router from it's default IP address to aid a little with security

[LesD]

Ah I see but the likes of yourself and others that are up to things like this are, I guess, beyond needing to refer to my relatively simple beginner's guide. 

One thing that has puzzled me and I have meant to ask about before is that I have under:

Local Network – Status
Gateway:  192.168.1.254
IP Network:  192.168.1.0
Subnet Mask:  255.255.255.0
DHCP Range:  192.168.1.64 – 192.168.1.253

The puzzle is this, why with potentially 256 addresses is the DHCP Range restricted to 253-64=189 and furthermore why is the first one in the range 192.168.1.64 ? 

With my Netgear DG834 the range started at .2
The access was via .1 as follows:http://192.168.0.1/ in the browser address bar.

Could this be to do with the 2700 having Wireless capability while the DG834 did not? 

[Glenn]

Les, the DHCP range is set from the Local Network > Configure tab, mine is set from 2 - 15 with 254 being used by the router.

[LesD]

Les, the DHCP range is set from the Local Network > Configure tab, mine is set from 2 - 15 with 254 being used by the router.

Presumably you have chosen and made this setting range for yourself.
I have not changed anything on this tab so I am assuming my settings are defaults after the factory reset I did before doing the other setup items to get connected to IDNet. Do you think that this could be the case?

[Rik]

My SBC model ran  from 64-253, Les, but the dual SSID model runs from 1-253. Foibles of firmware - confused the helll out of me.

[g7pkf]

The 2700 has a weird but nice way of bridging multiple ip's (been playing this weekend with a voip server accessable from the internet)---wifes away for weekend

you can firewall protect (or not) the second ip.

local addresses served from the first/router can be accessed by the second wan ip directly (but not from the net directly).

If you don't understand what i just said you don't need to know.

If you did then you might need to know.

If you did and a lightbulb went on your as sad as me.

dean

[Rik]

I'm a don't need to know, Dean.

[g7pkf]

I'm a don't need to know, Dean.

Still as sad as me though

[Rik]

Indubitably.

[LesD]

Still as sad as me though

That's three of us then! 

[LesD]

My SBC model ran  from 64-253, Les, but the dual SSID model runs from 1-253. Foibles of firmware - confused the helll out of me.

Nothing to do with reserving part of the range for Wireless then as I wondered about mine. 

[Rik]

It doesn't appear to be.

[Sebby]

I'm a don't need to know, Dean.

Me too. Actually, I'd like to know.

[LesD]

Rik,

At Reply no. 41 above I attached a PDF of the Single SSID 2700 setup method that you have have posted here:

http://www.idnetters.co.uk/forums/index.php?topic=8927.msg197903#msg197903

In Alan's post above this one he offers a PDF guide for the Dual SSID Setup so if you attached the one from Reply no. 41 to Reply no. 1 of:

http://www.idnetters.co.uk/forums/index.php?topic=8927.msg102417#msg102417

a Single SSID Guide in PDF format would be readily available too!

It now is. Thanks, Les.

[Mytheroo]

have just ordered a 2700hg from ebay (£19) to see if I can get better sync. wag54gs and zyxel660 both drop connection when I get an incoming call. 63db line, 6db SNR up and down. 1120/720 on average sync-wise. Am plugged into master socket via an inline filter (NTE5 frontplate made no difference), no phone connected but when I ring my landline the sync normally drops.

Anyone ever had similar troubles?

[Rik]

Have you tried a new filter, Myth?

[Inactive]

I use a Zyxel 660, I have also tested using a 2700, never had any dropped connections with either Myth.

[Mytheroo]

have tried two inline and an NTE5 faceplate, no difference. I'm on TPON with overlay thingy, when I moved here IDNet said they probably couldn't raise any tickets with BT for anything because it's basically a broken system to start with.  I'm toying with the idea of blocking incoming calls (neither of us here use the landline except in emergencies) but keeping outgoing if that's an option. There is another on this estate with IDnet but who lives nearer the exchange, he's got 2.7 sync or so with the 2wire so it might be the solution.

[Mytheroo]

In, you dont have high attenuation though do you. Did u get better sync with the 2wire? I'm wondering if the upload snr is my problem. Am on supermax so i'm stressing that part  more than most

[Sebby]

I use a Zyxel 660, I have also tested using a 2700, never had any dropped connections with either Myth.

But then you do have a particularly good line, In...

[Inactive]

In, you dont have high attenuation though do you. Did u get better sync with the 2wire? I'm wondering if the upload snr is my problem. Am on supermax so i'm stressing that part  more than most

No, I have a fantastic line, I am only about 30 yards from my exchange, sorry that doesn't help you.

[Mytheroo]

grr     

[Mytheroo]

on 2nd 2wire now (1st connected twice then died with red flashing dsl light) but both connected with snr of 15db. The zyxel connects with 6-7db snr downstream. Is there a setting in the 2700 to tell it to try a syncing with a lower snr?

[Rik]

There isn't that I know of, Myth. 15db suggests that the target margin has been raised by BT. Could it be that the Zyxel is reporting incorrectly?

[Steve]

Are the sync rates the same for the Zxyel and 2wire?

[Mytheroo]

have just ordered a 2700hg from ebay (£19) to see if I can get better sync. wag54gs and zyxel660 both drop connection when I get an incoming call. 63db line, 6db SNR up and down. 1120/720 on average sync-wise. Am plugged into master socket via an inline filter (NTE5 frontplate made no difference), no phone connected but when I ring my landline the sync normally drops.

Anyone ever had similar troubles?

I know i hijacked this thread, sorry 

The other two sync at significantly higher downstream rates. Maybe I've been set to 15db but the other two don't do their job properly 

[Sebby]

It sounds more like a faulty filter. Have you checked that?

[Mytheroo]

2 different filters and a borrowed adsl faceplate. No difference with the drop-outs when phone calls come in

[Rik]

Weird, I'd have sworn that would be a filter. The only other thing I can think of is a rare line fault, HR.

[Glenn]

My line used to drop if the phone rang, it was a bad electrical earth somewhere outside the house, the BT chap found it and swapped the phone pair.

[Mytheroo]

interesting.

I just rang my phone and the line dropped again. Seeing as I dont use the landline for incoming calls, I'm going to see if I can get them blocked at source.

[Rik]

BT do have an incoming only service, Myth, but I don't think there's an 'outgoing only' equivalent. Best to have a word with support and get BT to check the line.

[Mytheroo]

thing is, when IDnet said they'd try give me broadband on this line, they kinda said they wouldn't be able to raise any 'faults' with BT as it was a hit-and-miss kinda affair in the 1st place. I dont want to annoy IDnet :-)

[Rik]

This is a specific fault though, Myth. It's worth talking to them at least, they won't get annoyed.

[Sebby]

I agree. There's a clear fault, it's not just a poor line like some.

[Mytheroo]

ok, just logged a fault with IDnet for this issue (not a rapid person am I? :-). Shall let you know what happens.

[Rik]

The tortoise won the race, Myth.

[Mytheroo]

    ...what race?  dang that sneaky tortoise

[Rik]

I'm just haring off now...

[hairyman]

I have come to this post recently. Why does this 2700 two wire router attract so much input and interest?

Can someone enlighten me without me having to go thro dozens of one line posts? Is it customiseable ?

I have a backup router from Creative that cost me £9.00 brand new from the "the man who can" at Scan.
It is useful both as a backup and to eliminate a variable when I do line tests here.

Hairy

[Sebby]

In a nutshell, it's very good for poor lines. You've got full sync, so you wouldn't really benefit, but for those of us on long lines, it usually syncs higher than any other router.

2Wire don't sell directly to the end-user. In the UK, BT Business Broadband supply this router (badged as BT) to their customers. Lots of people sell them on eBay, and they usually go for very little money (often under £10!).

I hope this helps.

[dicksilk]

Caught this forum via Google, had to reactivate my ancient JUNO account to register... however, I was reading on the 2WIRE UDP "what's UDP" topic and was *just wondering: *
How to block the new hot phone app out there:  KillWiFi ?  I'm starting with a non-broadcast SSID, encryption, and BLOCKING all but known (only 2) wireless MACs.  In the process, I learned a BUNCH about this blessed HPNA system... more than I bargained for!

The problem (theoretically) is this:  if KILL WIFI clones an IP address and just crawls right into bed with my router's wife, so to speak, how can she know it's ME and not the clown / clone filling her "I PEE" sockets?  (sorry about the puns....)

[Steve]

 

Know nothing about this App and not a 2wire user, presumably this App has to get past the encryption first?

[dicksilk]

My son came over to show it to me off his droid phone.  I recently had a minor (?) stroke and am convalescing at my mom's.  Apparently no matter how many times I set this system up, after a year or more I come back to find her entire wireless security is reset to "DEFAULT" which is badically DEFUNCT.  So I asked son to show said function, and *presto!* both my laptop and her wifi desktop went kaput.  Also infected us with adware from ask.com.  Have to kill most recent registry backup and restore from one prior to keep out the returning prefetch insects and restore aphids.  Actually had to kill Mom's entire backup/restore cache.  Not sure exactly what it did to the 2Wire router, but I'm about done with the thing.  Gonna challenge him to try again for $50.

[Steve]

It's not difficult to reset that router or indeed any router and then the WifI password is usually written somewhere on the box.a

[Tacitus]

It's not difficult to reset that router or indeed any router and then the WifI password is usually written somewhere on the box.a

It all depends on whether you kept the box.......   

[Steve]

I should have said the base of the router but was trying to avoid repeating it three times in the same sentence.

[dicksilk]

My son came over to show it to me off his droid phone.  I recently had a minor (?) stroke and am convalescing at my mom's.  Apparently no matter how many times I set this system up, after a year or more I come back to find her entire wireless security is reset to "DEFAULT" which is badically DEFUNCT.  So I asked son to show said function, and *presto!* both my laptop and her wifi desktop went kaput.  Also infected us with adware from ask.com.  Have to kill most recent registry backup and restore from one prior to keep out the returning prefetch insects and restore aphids.  Actually had to kill Mom's entire backup/restore cache.  Not sure exactly what it did to the 2Wire router, but I'm about done with the thing.  Gonna challenge him to try again for $50.

SO:  after much ado and a lot of resetting...
Turned OFF SSID broadcast, set wep shared encryption key, and used the 2-wire's MAC filtering to ONLY allow my laptop and the desktop's wifi adapter.  No problems since reloading my op system as well (XP SP3) to completely kill all malware / adware and system restore backups.  Also reset desktop's advanced wireless settings (and mine) to "connect even when SSID is not broadcasting" knowing I can easily check the 2WIRE and/or physically reboot it when necessary.

Just a note about "filters" that was mentioned earlier-- (sorry for no quote, but I'm still learning to navigate this thread more succinctly [?] ) -- my son mentioned that while he was "rooting" his phone, which was also in the brief conversation we had about KillWiFi, some filters were reset to 0 (zero) and max (whatever those max filter digits are.)  He has yet to stop by on the $50 challenge, so when that occurs, I'll post the updates.  I have not personally reset *any* filters, aside from reloading the operating system.

One other tech note of mention:  there are two passwords on the 2WIRE router:  one for the home basepage of the router, and one for the network ID.  Changed the ID (as mentioned above) to shared WEP (I have a password I use as standard so as not to forget it) and ALSO changed the 2WIRE's home page password seeing as that one was a buggar to find (with my altered eyesight) and reset the hint so it won't be forgotten in the future.  Again, no problems since all this, but I'm HOPING I've licked the KillWiFi issue.  Will update later, promise.
