7805u wifi card trouble

I am new member but I have always come to this site for help with problems regarding my 7805. I've had nothing but problems with it from day one. Recently I was reading a thread here about upgrading the wifi card ( http://forum.notebookreview.com/gateway-emachines/622922-upgrade-wireless-bluetooth-fx-p-7805u.html) after having problems with my 7805 dropping my wifi connection repeatedly after installing win8. I purchased an intel centreno 6300 ultimate N card and installed it. Now the wifi will not connect and the wifi light on the keypad won't light up. I've checked the device manager and it show that it's working and the latest driver is installed. I've reset the cmos and still no luck. Is there something I'm missing here?

Just tried formatting and reinstalling a clean copy of win8 and still no luck. I've tried the card in both slots and still nothing. Any ideas?

 

Are you sure that it's not a card meant for Lenovo?

 

I ordered the same card that was mentioned in the above link(6300 ultimate n). How would I check to see if it was meant for lenovo?

 

It usually mentions Lenovo by name in the description or on an auction.
Serial/part number might also solve this.

 

Tanware mentioned some users had problems, possible blacklisting?

Was the card pluged in original wifi slot and 100% sure attennnas were plugged and seated?. The 6300 is 3 wire but I have used it two wire at lower speeds as my router is not that fast at 5G.

I just had mine apart for fan problems but may go back in next week. The original works fine so had no reason to test my 6300.

 

The only way I know of getting them working is to block off the switch pin and use the secondary slot. This is a hardware hack so I do not promote it nor have documentation of it but there are other threads here.................

Edit; with the P79xx I have there are no wifi issues to speak of under windows 7 or 8. You do have to tweak the settings though for best connection and bandwidth for the 5100...................

 

I looked the card over and there is no mention of lenovo on it. I found a pic of the true intel 6300 and the stickers don't match so the one I have must be from a lenovo. Thanks for everyone's help!
