Router Newbie, pse have patience

[Wingco1]

I have just bought a D-Link G604T and wired via ethernet to my puter. Wireless is turned off. Sync on Home Max is 8128, speeds generally good around 4.5 to 5.5 mbps. Pings seem higher than my old Speedtouch 330 modem, but not a great problem.

I have noticed that the outgoing MTU is 1400 with no way of tweaking it. Is this picked up via IDNet in some way or just the router setting?.

[Jeff]

Greets Wingco, took you a long time to post here m8 Welcome

I believe that on the 604T you can change MTU via "WAN Settings".

I`m sure I`ve sorted this out for someone else before, deja vous kicking in

Change to 1500

[Coopes]

Hi Wingco, I have the same router, you can change mtu log into router click settings then connection one, or where you set up your user & password.

[Wingco1]

Hi Jeff, believe it or not I lost the bookmark and had to search for your link.

Thanks Mark found it and changed it 

I`ll probably have a few more questions shortly as I`m intending to try to add a laptop via wireless. Currently have one puter connected via ethernet and the WLAN switched off.

[Jeff]

No probs Wingco

[Coopes]

No prob mate

[Wingco1]

As a matter of interest dslreports didn`t like me using MTU of 1500, something about uploads lower than MTU. Could be a Win98SE thing. Anyhow ran the MTU checker in TCPOptimizer and it suggested what I was using 1430. Reset and dsl reports is happy again.  8)

[Jeff]

Thing is, you have a router MTU setting and a windows MTU setting. Problems occur when the router MTU is lower than windows MTU, that`s why I suggested 1500. BTw nowadays advise not to set MTU higher than 1458

Check your router setting, I bet it is still at 1500 as TCP Optimiser changes windows MTU

I use 1430 too

[Wingco1]

Oh no it isn`t  after running TCP Optimizer I changed it back 

I ran another test with router MTU 1500 PC MTU 1430. dslreports says, "Upload packet less than your MTU (FAQ #1492)"

Full result,

[Jeff]

M8, you have entered your Speed (advertised) kbit/s: 8128, is this what you are synched at? Check out my settings using Dr TCP as you have a slight problem

[Wingco1]

Changed my settings as you suggested;

[Jeff]

Ah! Expired URL ... I`ve come here too late in the day man!

[Wingco1]

Basically Jeff I suspect the rwin might have been too high for my w98SE box, There were a few retrans errors and transfer efficiency was 99%. Left it for an hour and every test showed the same result.

I lowered the rwin and things returned to normal, no retrans & 100% efficiency.

[Wingco1]

Mark would you do me a favour?. Have a look in the router interface STATUS/DSL STATUS and tell me what you have against PATHMODE please.

[Coopes]

Hi Wingco I have interleaved, hope that helps

[Jeff]

Coopes, perhaps they have ascertained that your line should be interleaved. Helps stabalise your line but if u game I`ve heard this may be a problem.

Remember, I didn`t think you`d get Max with your old 1Mbit stats, at least not much better than what you already had

That`s what I have and it`s bugging me. I had a steady 2meg connection before upgrade to Max. I had a problem with my speedtouch just after regrading which caused a loss of sync on a couple of occassions. I replaced the speedtouch with the D-Link and come accross this.

I`ll wait until after Easter and email Simon.

[Jeff]

 We need to get this interleaving sorted, that`s a a fact ... I was on the understanding that it would be switched off by default but may be turned on for lines experiencing sync problems.

Wingco, if u were happy pre-Max, raise it with Miriam

[Wingco1]

Will do Jeff. As a matter of interest I don`t really know which of these figures refers to SNR can u help;

Connection Status     Connected
     Upstream Rate (Kbps)    448
     Downstream Rate (Kbps)    8128
     US Margin    28
     DS Margin    9
     Modulation    MMODE
     LOS Errors    0
     DS Line Attenuation    30
     US Line Attenuation    30
     Path Mode    Interleaved

It appears I have interleaving switched on   a couple of other 604 users have Pathmode = Fast Path. This is obviously down to the BT software, however it doesn`t allow much room for diagnosing faulty gear.

Four/five resyncs in a very short space of time has triggered the interleaving switch 

Have emailed support but don`t expect a reply till Tuesday after all they are entitled to their hols.

[Coopes]

I was wondering the same thing about SNR

[Coopes]

I have had interleaved on from the beginning. My speeds have got worse
over the week. My 10 days are up today, my speeds have not moved all day
2432 no matter what I do, my best had been up to 3663 and it was running great at that
could be that is what BT have set my line at. 

[Jeff]

Wingco, your stats are near perfect! "DS Margin" is your SNR ... we reckon that line resyncs lower when u maintain an SNR in between 3 and 6dB. Seeig as yours is 9dB with a full 8Mbit sync, u can safely say that your line is good

Coopes, remember m8, not everyone can connect at the full 8Mbit. Remember post Max when some were stuck on even a 256kbps because of factors such as distance from exchange, quality of line etc. Same thing for you I`m afraid, but what you should be looking at is your throughput, this is important from your perspective. Try a couple of speedtests to see how your line performs but again, remember that your line resyncs to reflect current line status

As far as the interleaving goes, I`m at a loss here. I need help from Simon on this ... he`s away for the weekend but i`ll ask him to input on it

[Coopes]

Cheers Jeff

Interleave explained...

[Wingco1]

Interleave explained...

That explains things very well, however it doesn`t explain what triggers it    I had a very stable 2meg connection with good speeds using a speedtouch 330. On being regraded to MaxDsl I decided to download the new "highspeed" drivers for the speedtouch whilst I decided what router to get.

I would assume the Speedtouch "upgrade" may have failed because it kept dropping the connection, although it had been OK for a couple of days after the Max regrade.

After about 5 resyncs I turned the puter off removed the speedtouch and replaced it with a router. It was then that I noticed Pathmode = Interleaved!

I can only assume that the BT software had kicked in . if this is the case it doesn`t allow much of a chance to troubleshoot line probs . Quite obviously once interleaving is on the software doesn`t recheck if it`s still needed.

I don`t know if Interleaving is affecting my speed or not. I`ve consistently synched at 8128/448, what I do know is that it`s put around 10ms on pings .

I`ve emailed support and asked them to check my line, however I don`t expect a reply until Tuesday at the earliest.

[Bill]

I must admit I hadn't thought much about interleave if your line stats improve... I suspect that once it kicks in that it stays in until BT remove it (which I think they will do at the request of the ISP).

Do let us know if yours does drop out without intervention, it would be a useful piece of information to add to what BT aren't telling anybody 

[MarkZX12R]

Looks like my Max dsl has settled down now to around 3.4 meg peak speed....does get lower than that depending on the time of day though!

[Coopes]

tried the ring wire trick today speeds gone up from 2345 to 3168 big difference.

[MarkZX12R]

I might try that then....which wires do i disconnect?

[Coopes]

The one I disconnected was the one with the most orange on it I think it was in block 2

[MarkZX12R]

The orange one it will be then

[Toxteth_OGrady]

I think it was in block 2

Wrong - the ringing wire is connected to terminal 3; it's mainly orange with widely spaced, narrow white bands.

See here.

Whatever you do, do NOT cut the solid orange wire into terminal 2 - that's one of the two BT master line in wires!!  The other BT master in is solid white into terminal 5.

[Coopes]

I did say I think, and it is mostly orange. I didn't cut mine anyway, I disconnected it.

[MarkZX12R]

Oh well...i only have 2 wires going to the BT A and B connectors...one blue and one white or pinkish colour.

There are lots of wires in there but only the above two are connected!

[Wingco1]

Mine had a solid orange coloured wire in terminal 3, this is the ringing wire which I removed. Terminal 4 has an orange and white wire which is not used but connected for neatness accoring to your link, which I also removed.

[Wingco1]

Has it affected your sync rate Mark ?

[Coopes]

Yeah mate, gone from 2345 to 3260

[Coopes]

I did say I think, and it is mostly orange. I didn't cut mine anyway, I disconnected it.

TOG sorry if this post sounded nasty, when I read it back after posting it looked nasty
it wasn't ment to sound that way.

[MarkZX12R]

but how come i only have two wires and none of those is orange

[Coopes]

Mark how old is the house you could have old BT wiring don't know if they have changed
the colours, but I bet someone on here will know.

[Toxteth_OGrady]

TOG sorry if this post sounded nasty, when I read it back after posting it looked nasty
it wasn't ment to sound that way.

np m8, didn't read it that way at all - I was more worried about the fact you mentioned terminal 2, which if Mark had disconnected that it could have caused his connection to be lost altogether.

As for variation in colours and lack of standardisation, posted later, then it does mention the likelihood of this in the link I posted - would take all the fun out of it if it were all bog standard and easy!!!

Now that's a handy site. Have a karma point on me sir.

House is ten years old so not that old.....no problem though, i shall leave it as it is

[Jeff]

Nothing much to say here but just wanted to make a point

Bill, I`m au fair with interleaving but what I meant to say was that I was on the understanding that by default, interleaving thru IDNet was turned off by default, and if users here are showing an interleaved line then I need Simons input as to why this is

I reckon it`s switched on for those with poorer line stats to try and obtain a better sync rate, perhaps part of the Rambo training?

That's pretty much, as I understand it. Most likely reason to turn it on seems to be if the exchange has several retrains in rapid succesion, the same number over a longer period don't have the same effect. But as with all BT actions on MaxDSL, the actual reason may be entirely different!

Well Wednesday will do
