Wifi not working

[TheMightyChmig]

Ever since I built my PC, I've been having wifi problems. Here are it's specs:

 

• CPU
  Intel Core i5-3570K
• Motherboard
  MSI B75MA-P45
• RAM
  Corsair Vengeance Black (8GB)
• GPU
  2GB XFX Radeon HD7870 Ghz Edition
• Case
  NZXT Source 210 Elite
• Storage
  Western Digital Caviar Black 1TB HDD and a Samsung 840 Series 120GB SSD
• PSU
  Corsair CX500M
• Display
  Hannspree HL272HPB 27.0"

Some background: I orginally pirated Windows 7 Ultimate 64-bit. Eventually Windows found out it wasn't genuine, so it did the usual no background, no essentials, and no updates thing. I installed an ASUS PCE-N15 wifi card. It worked for about 2 weeks (but gave me pretty bad speeds), and then died on me. Tried reinstalling drivers, did usual troubleshooting things, didn't work. I had it RMAed, got a new one, reinstalled it, but to no avail. I thought that pirated Windows was causing the problem, so I stuck with ethernet (the reason I don't want to use ethernet it because I have to drag a cable halfway across my house from my PC to my router).

 

After a while a time came when I decided to register Windows. Shortly after doing so I got myself a new wifi USB thing (a TP-LINK TL-WN725N). I used the drivers on the CD; no luck. Then I got new drivers from their website; still didn't work. The unit itself works (as in it powers on and flashes its green LED), but doesn't see my wifi signal nor any others. Since I experienced similar problems with my ASUS card I decided it probably wasn't a manufacturing issue.

 

So here I am with a (possibly) dead wifi card and a non-working TP-LINK wireless USB adapter. I need help! Any suggestions?

Honestly at this point it's just trying another card. For some reason wireless adapters for PCs suck and never last long

Nope, slot is okay

Gaaah I'm sick of RMAing and buying things  :angry:

Does the PC find the card in the Device Manager ??

How old is ur router and modem

[TheMightyChmig]

How old is ur router and modem

5 years? Something around that

 

EDIT: They both are fully functional. I can guarantee you it's not a router/modem problem.

well maybe the wlan signal is just too weak

Doubt that. My laptop wifi works perfectly fine from the same place my computer is.

tp-links stuff is absolutely crap first off I was stuck with their horrible modem/router for a while and it didnt even fully support wireless N also if possible try them on different computers if they still dont work then the problem is with them if they do work reinstall windows if its that big of a deal
