Limited or no connectivity.

alan · Apr 12, 2007, 17:52:57

Can anybody help please ?.. When I try to go on the net with my PC I get "Limited or no connectivity"
I have a wireless router and it works OK with my Laptop (which I'm typing this on) its just the PC.
I've looked at Local area connection and tried to repair it and it just says "Windows could not finish repairing the problem because the following action cannot be completed:
Renewing your IP address.
.
Doing a Google I have D/Ld a patch which could have cured it but no joy.
.
This is about the 3rd time its come against this. I don't want to restart my router
now I've got the fault on the go.
I missed support by 10 mins.
.
Any ideas what I can look at next please.
.
Alan

Restarting the PC should cure it.

If not try from the command line(COMMAND PROMPT tool in accessories) and type ipconfig /all this will give you information and options for renewing the connection addresses.

Thanks DB for quick reply. Restarting the PC dosn't solve it...
I've followed you IP thing.. I have
autoconfig IP address 169. xxx.xx.xx
Subnet mask 255.xxx.x.x.
Default gateway which is blank.

Can you please tell me where to put the address in the nicest possible of ways!!
.
Thanks

Try typing ipconfig /renew in the command prompt.If you still can't get a connection it sounds as if your machine is not seeing the wireless connection.

(Typing ipconfig /help will bring up other options.)

Hi Alan

Can you start by using a wired connection to the PC?

An ipconfig /all should return something like this:

Windows IP Configuration

Host Name . . . . . . . . . . . . : Computer name
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Unknown
IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . . . : No

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :

Ethernet Controller <<<< varies

* Check the manual for instructions. It will usually start immediately after the address you login to the router interface.

Rik..
.
My PC is wired to the router.

I have everything up to including Default Gateway which is blank by the way.
It dosn't mention anything else thereafter like you have.

Unfortunately, I'm just going off for the night.

When you double-click on the 'modems' icon in the system tray, then properties, you should get a screen like the first shot below. Highlight the TCP/IP settings, then click on properties, does it look like the second shot?

Thanks Rik..
.
Yes its identical to those.
I think the easy option is to keep re-booting the router when it happens, until I can explore further.
Thanks for your and DBs help. If I get to the bottom of it I will advise further.

Alan

If you reboot your router too often you will loose your line profile.

What software firewall are you running?

alan · Apr 12, 2007, 19:27:46

That's what I'm afraid off.
Preventon firewall which I've had for about 9 months.
.

DorsetBoy · Apr 12, 2007, 19:30:04

I don't know that firewall...........can you disable/shutdown the firewall for a while and try repairing again from the connections icon?

alan · Apr 12, 2007, 19:33:09

Don't know if its coincidence or what but all this trouble started when the latest Central pipe was installed. No problem prior to this. I did speak with IDnet and they had BT test my line and could not find fault.

DorsetBoy · Apr 12, 2007, 19:37:15

If the laptop runs ok via the wireless router then your line and router are ok.

The problem is that something is stopping your PC from aquiring the address from the router.
Try repairing with the software firewall off.

alan · Apr 12, 2007, 19:42:25

Firewall disabled. Repair done but get the same response as #1.

DorsetBoy · Apr 12, 2007, 19:52:57

Right,try typing ipconfig /renew in the Command Prompt.

If that does not do anything you will need to check the lead to the router,check in the routers web interface to see what network connections are running ,can the PC and router "see" each other?

If you are still getting no joy then post details of your router make/model etc and we will try to work from there.

Have a look to see if there is a troubleshooting /diagnostic system in the router.

Do you have a spare modem or router that you could try instead of the wireless unit?

alan · Apr 12, 2007, 20:29:24

Ipconfig /renew... Nothing happens.
Changed the router cable, still connect problem.
I cannot get into the router details on the PC
because it needs the net as far as I know to get the details.
Although, I can get the details of the router on the Laptop of course.
I dont have a spare router. Only give it away a few weeks ago.
Will borrow another one for the week-end.
Its a Zyxel 660 HW router with up to date drivers.

alan · Apr 12, 2007, 20:40:19

Thanks again DB.. I'll call it a day and see what a re-boot will do tomorrow.
I'll uninstall/install the router and see if that will cure.
.
Regards
Alan.

Lance · Apr 12, 2007, 21:27:13

I'm confused by what you mean, Alan. You shouldn't have any need to install routers on a machine. It should be a case of booting up the router and then plugging in the network cable. Normally, to configure a router you would open your internet browser and type in the IP address (normally 192.168.1.1 for your router - I think). There shouldn't be a need to install anything on your computer at all unless you are using a modem, in which case you need to have the modem drivers installed.

alan · Apr 13, 2007, 05:45:05

Thanks Lance..
Stupid me.. That would explain why I couldn't find anything to uninstall. I was thinking it was like a piece of software. I thought it had hidden itself somewhere. Its the old grey matter creeping up on me.
Yes it is 192.168.1.1.
.
Regards
Alan

DorsetBoy · Apr 13, 2007, 05:56:26

Another place to seek help is the Zyxel support forum hosted at Broadband Buyer........

ZyxelForum

As I said before though you should be able to see what connections are made by entering the web interface of the router 192.168.1.1

Lance · Apr 13, 2007, 08:17:56

Have you tried changing the LAN port on the router you are using? Its a long shot but the particular port you are using could have become faulty.

Rik · Apr 13, 2007, 08:23:35

It might be worth re-installing the network on the affected PC (though I'd go through the router interface from the lappy first, just to make sure there's nothing odd set in there).

Control Panel > Add/Remove programs > Add/Remove Windows Components > Networking services. Yous should see a screen similar to the shot below. Untick, do the removal, re-boot, reverse the process.

I had already tried the Cable in all 4 ports. Still the same result.
When I got back from the hospital this morning, living in the sticks we've had a power cut, which in turn, with the Router set to Auto connect as corrected the connectivity problem.
Its put my BRAS profile down from 7000 to 6500 so nothing too drastic this time.
Rik, I've done as you have suggested with the Networking services and will now see if I can stay connected for more than 2.5 days.
This as been on/off for several weeks now so he's hoping. Incidentally, I have all 5 boxes ticked in the Network services is that correct?.
.
Thanks all for help and hopefully this will be an end to it. I will no doubt let you know.

Rik · Apr 13, 2007, 12:22:13

Hi Alan

If re-booting the router cures the problem, can you borrow another make/model to try for a few days? I've had the situation where the router has 'stalled' on me for no apparent reason, and only a re-boot would fix it. Possibly, your router is hanging due to noise spikes, either from its mains adaptor or the Cat 5 cable. Might be worth trying a swap on that too.

It's OK to have all five boxes ticked if you need them all. Most people don't though.

Toes crossed for you.

alan · Apr 13, 2007, 12:29:39

Thanks Rik.. I'm borrowing another router at the week-end as a standby for a few weeks so will have another to try if the problem persists. I had already tried another Cat 5.

alan · Apr 16, 2007, 13:27:59

Ah Well.. I managed 76hrs this time, before the loss of connectivity again.
Profile now dropped from 6500 to 4000... and I thought it would take no more than 10 before your profile would be affected. On this occasion it was two re-boots.
I think a new router is the cards for tomorrow.

Rik · Apr 16, 2007, 13:48:54

The theory is that it takes 10 re-syncs in any 60 minute period to trigger DLM into pushing your profile down. Whilst that may be generally true, a bad burst of noise, as happened to me on Friday, can have the same effect - without you being aware of the re-syncs.
