Dear All,

I have an ongoing problem which I posted about before and thought I had half-solved, but now cannot work it out.


My pc refuses to talk to my router.

Here are the facts:

I cannot log on to my router using 192.168.0.1

I know my router is fine, as I can connect using my laptop, through any of the ports. And I know the leads are all fine for the same reason.

The little indicators on the router say that it is connected to my pc, and the light on the ethernet card says it is connected to the router.

I thought it might be the fault of the ethernet card, so I changed the driver a few times, uninstalled it, reinstalled it - all the time with windows saying to me "this device is working properly. Honestly, go and have a cup of tea and put your feet up - this device is just fine"

So, not wanting to trust windows too much, I went and bought a new ethernet card. No difference.

I thought it might be the pci slot, so I have shifted it around. No difference.

Windows is even saying to me that it has found a local area connection - which, when I look at the properties, says it is connected at 100mbps. I can "disable" and "enable" at will and it seems perfectly happy to lie to me, and say that it is connected.


What am I not checking? What more can I do? I have no device conflicts. I have two different browsers - (FireFox / IE) - so I am fairly confident its not a browser problem - there is just zero communication taking place.

I only just noticed this forum, so this is a re-post (I've closed the other thread down), but hank needed to know that I obtained an IP address automatically

If anyone has any ideas (other than the axe solution - which it really won't take much to push me into) then I would be massively grateful.

Many thanks as ever

Tom

If you have an opportunity to get on another computer and download a free program called

winsockfix.zip it will fit easy on a floppy

Put it in that computer and run it.

Perhaps you have a corrupted winsock.


Just search the name winsockfix.zip in the google browser and it will come up.


I did not note that your laptop gets online in the other forum so that rules out a router problem.

Thanks for keeping onto this one, Robbie. I just tried that - no luck, unfortunately.

Are you using DSL or cable? If you are using DSL go to your router settings and make sure that obtain ip address automatically is turned of and ppope is enabled. you have to type in your user name and password for you to be connected to dsl. if you are using cable, than make sure obtain ip address automatically is on in your router settings.

Are you sure that 192.168.0.1 is the routers address? Most router's I've worked with use 192.168.1.* or 192.168.2.*.

Is it only the router that you can't access, or can you not get out the the Internet either?

To save time, I'll assume it's the latter and recommend some basic troubleshooting steps:

1) Connect your computer to the router with an ethernet cable. Is the link LED on the computer's network card lit? Is the link light on the router's port lit?

2) Does the computer have an IP address? Is it in the same subnet as the router (e.g. 192.168.0.*)?

3) Can you ping the computer's IP address from the computer?

4) using ipconfig, is there a gateway address listed? Can you ping it?

5) You say you can't logon to the router. Can you logon to sites on the internet?

If any one of these steps fails, please post back and let us know. If none of them fail, please post back and let us know that also. Either way, we'll have something more to go on.

Shaun - its DSL, but I cannot connect to the router. (I know its working by using my work laptop through it - but because this is a VPN I cannot access the router using this machine - and I don't have admin rights on it)

iamc - yes, I have the right router address (but I've also tried the other suggestions, too...!)

it is both. To take your questions:

1) yes and yes

2) No its not - but then it never was.

3) I can ping it

4) No gateway address listed

5) No


In case it helps the analysis, here are the results of ipconfig /all:

w2000 IP Configuration

Host Name...: mycomp
Primary DNS Suffix . . . .:
Node Type: Broadcast
IP Routing Enabled . . . : No
WINS Proxy Enabled . . . : No

Ethernet adapter Local Area Connection 2:

Connection-specific DNS Suffix .:
Description. . .: [ethernet card name]
Physical Address . . . .:00-50-FC-EC-E0-17
DHCP Enabled: Yes
Autoconfig: Yes
Autoconfig IP Address . . :xxx.xxx.xxx.xx (not posting it on the internet!)
Subnet Mask . ...:255.255.0.0
Default Gateway:
DNS Servers:

and thats it. Typing that out, some things seem wrong (like IP Routing Enabled = No) but I have zippo experience of this stuff, so feel like a total dolt.

Many many thanks for your ongoing effort

Tom

169.254.x.x is the IP address range that Windows automatically assigns when it can't contact a DHCP server. For whatever reason, your computer isn't getting an IP address from the router.

Try manually configuring an IP address. Use 192.168.0.x, where x is a number not in use by any other computer on the network. Use 255.255.255.0 for the subnet mask. See if you can connect to the router after doing that.

Tried that - no joy. Tried several different ones, in fact.

Still can't connect to router or internet.

When you manually assign an ip address to the computer, can you ping that address from the computer? Are you absolutely sure that 192.168.0.* is the address range of the router?

I can ping it from the computer. I cannot ping the router.

I have borrowed another laptop, and can now get into the routers settings. Does this help? I don't really know what I'm doing in there. (I can ping the router using this laptop, ping itself - but cannot ping my pc)

That last paragraph answers the question - I am sure of the routers address!

Thanks
Tom

this may be a silly question, but what is the make/model of the router?
who is your ISP?

Another silly question. Since both router, NIC and PC seems to works, can you possibly be using a crossover cable?

The router is a Netgear DG834 (not wireless) and my ISP is BT.

I don't know about the cable being crossover (what does that mean?!) but I have 2 - and both work with the laptop, and both have worked before with the PC.

If both cables work with the laptop, they are normal CAT5 and ok. It was worth a try.
Out of ideas now.
Good luck

Fantastic News - it works!

And you'll all be pleased to know it wasn't something you could have guessed at (although, on a different thread, I read someone had also had to do this)

On the attempted 5th (out of 6) PCI slot, it worked. I have no idea why. It just won't work in the other 4 slots.

I think that probably means that my firewire card won't work now, but I can live without that for a while.

Thank you all so much for your advice - I've learned a lot along the way.

See you around

Tom
