WiFi from Laptop to Router not working properly

Hey there

I have a very odd (to me at least) problem...

I have recently started using my laptop with a D-Link DSL 2640R wireless router.

Today my wireless went down (something to do with my ISP) and it still hasn't come back (5hrs later)...

Anyway when I try to connect to the router using the Intel Wifi Link 5100 AGN wireless adapter that is built into my Asus M70Vm I get the "Unidentified Network" name showing in the Windows 7 Network and Sharing Centre panel, I also cannot access the control panel on the router, nor can I ping the routers IP address.

But when I assign a static IP address to the wifi adapter and make the gateway the routers IP address (192.168.1.1) I can access the routers control panel (still cannot access the internet but that's down to my ISP).

I've also had a problem this afternoon where the LAN adapter and wifi adapter would not save the IP settings that I was trying to set, they had the IP address and subnet mask blank but the gateway was still there when I went back into them. I've solved that issue by reinstalling the drivers.

I have an XP install on the same laptop that appears to work fine with the router no problems at all (just the lack of web connectivity due to my ISP).

So I'm just wondering if anyone can shed some light on this, is the issue with the wireless happening because I don't have any internet connection, or is there something wrong with Windows 7, or my wifi adapter?

Thanks in advance for any help.

 

Sounds like a software problem. Are you using windows zero config or another connection manager like Intel ProSet?

 

I've tried both. Odd thing is that it's working fine this morning. I'm able to put IP addresses in and they save. I'm also able to not use static IP addresses and I can connect to my router as normal (still waiting for my ISP to resolve the issue with the line though so I have no internet via my new line. ).

Only thing I've done since posting is reset my router to factory defaults. So I don't know what caused the issue or why it's resolved itself.

 

Best guess: when your internet went down, your modem stopped supplying DHCP names to the router for your computer. I see you have DSL, so I wouldn't be surprised if this was the case. Without seeing your router/modem setup, I don't know if I could tell you how to make the router supply DHCP instead of your modem, but that's what you'd have to do if you want to avoid this in the future. Or you could just tell your ISP to get their act together, but if it's AT&T you're out of luck.
I'm curious... Since you set to factory defaults, have you gotten internet back yet? Can you? If you don't, it's most likely that you now have both the modem and the router trying to assign ip addresses (the function of a DHCP server). It can't be both, so choose one or the other. Good luck. Let me know what happens.

 

Thanks for the advice guys.

Found out the problem was that I fried the router (which was also the modem) Too hot apparently.

The router I believe was faulty because it shouldn't have got too hot and cooked, and that was definitely the cause of the drop of the DSL.

Replaced it with a new Belkin router/modem and all works fine now.

Although I still can't explain why my connection properties in Win 7 kept discarding half the IP address/Subnet mask info I put in.

Very odd.
