Is my WLAN (WiFi) adapter broken?

CF-52 Axxxxxxx

The BIOS recognizes the WLAN card and it is enabled. Windows 7 recognizes the card as Intel pro wireless 4965agn and automatically adds drivers. Everything looks ok. The switch is on. The card sees networks. I can connect fine to them (I tested on two different, one unencrypted and one WPA2 encrypted). So far so good but...

I don't have internet at all. No ping, no nothing. IPCONFIG looks good - I see my IP, DNS servers - all DHCP recognized... I can't even ping the listed default router.

I did update the drivers to the Intel pro wireless 4965agn official drivers from the intel website. It doesn't work.

I did disable Windows Firewall - no change.

I did disable the antivirus (Microsoft Security Essentials) - no change.

The Windows is quite "clean" and there are so few things installed on it. I am puzzled now. Is my adapter dead? But if it is, why it does see the networks and it can connect to them?

 

Try connecting direct to the router using a cable.

Check the router setup to see if something is set wrong. I got a used router and had to change setting to 8/35 before I had internet access. It would show up fine but could not communicate until I set it to match my ISP.

Try a different router. Maybe the router went T*ts up.

Try going to a free wifi location and test the wireless there.

Did the Internet ever work on this machine?

Try a Linux live cd. Boot from it and see if you have internet access. If you do, then it's a software problem.

 

check ur event log.

 

Try unininstalling & reseating your Wifi card. Try plugging in a known good USB WiFi adapter. If it works, probably a problem with your WiFi card; try another. They're cheap on eBay. If not, your problem may be software/OS related.

OH, sonuvacrap. You may have the wrong authentication/encryption type; make sure you're using the same WPA/PSK or WPA2 (NOT Enterprise - that needs a separate Key server and almost nobody does that at home) on Wifi card & router, same for TKIP & AES encryption. Or, you have WiFi Access Control enabled on your WiFi router. Add the MAC address for this WiFi card to the whitelist. Try turning off encryption in the router just long enough to see if you can connect. Also, are you actually GETTING an IP address assigned from the router, or getting an "Automatically assigned IP Address" in the 169.x.x.x range?

Or, you can like, try hitting it with a hammer.

 

Removed pointless post

 

Will the size of the hammer make a connection speed difference?::

 

Strange but a fact - two different routers were having issues with internet connectivity...

I bought and installed a wireless router in my home and the CF-52 works fine with it.

 

Glad you found the problem

 

... and I am glad that I didn't hit it with a hammer

 

But, you have 2 bad routers that you can hit with a hammer!

 

So ur real problem was the wrong AP-channel?

 

Yes, could be, but I am not sure. I think if they was broadcasting on channel 12/13 I wouldn't even see them (like it happens when I switch my home router to channel 13). But I was seeing the routers, connecting to them and then no internet.

The problem was definitely with the internet connectivity in the university (the two routers was there). I can connect in other locations with no problems. Case closed.
