Wireless network --- Help Me!!

leisuresuitlary · 22 Apr 2005, 05:21 PM

I have installed a wireless router in my house. The connection to the network works no problem but getting my computer to connect to the internet through it can be a nightmare (in the context of either a browser window or my antivirus updates). It works fine for a while but (usually) following a system reboot any browser I try just will not connect. Once this has happened the only thing I seem to be able to do to make it work again is to reinstall the wireless networking card. I have tried to use the repair tool which appears through rightclicking the system tray icon for a wireless lan connection but this tells me something to the effect of “ the IP address could not be assigned” – I cant remember the exact message.

Can anyone think of why this fault occurs. I don’t think that it has anything to do with some port-forwarding I set up from the router to allow a client to work properly but that is the only change I have made since things were working properly. Again, everything worked fine last night following the reinstall and this morning (following a reboot) there is nothing. Other computers on the wireless network appear unaffected.

Could setting up port forwarding to open a port in the firewall to allow internet explorer to work be the answer? If so what port do Avant and Firefox run off? What port does msn messenger run off?

Any thoughts?

Did you try putting it in other computers? Do you have SP2?

Dont have any other computers that would take it. Sadly I do not have SP2 - nor can I get SP2 for the obvious reason.

I am thinking that this is not the key issue however as I have reset the computer on a number of occasions and it is only the last three times that I have reset it (since the port forwarding was set up and as I said I can't think why that would cause this problem) that this has arisen - before this the computer connected to the the net OK.

I'm going to take a WAGuess and suggest that either 1) one side (router or workstation) is expecting DHCP - dynamic IP assignment - and the other isn't cooperating or is using attempting to use a static address. Since the problem began after you set up port forwarding, it is highly likely to be related to something that happened during that change (not necessarily to the fact of port forwarding itself).

This network debugging checklist might help you narrow it down.
Check the that router and computer aggree on how and what IP, DSN, subnet mask, and gateway addresses are assigned.
Could you redo the installation as you first did it, without port forwarding? If that works, then walk through the port forward and take note of anything that might affect one of the above assignments.

Good luck.
