I'm having a problem getting other devices to connect to the internet wirelessly. As long as the connection has a wired connection I can browse the net just fine but any wireless device either acts really slow before stopping completely (like only loading part of a webpage) or not connecting at all. I'm starting to suspect that Windows 7 is at fault since the problem occurred shortly after installing the new OS. I've also noticed that Windows 7 itself cannot find my wireless router and shows no option to connect wirelessly, only through local area connection. I've already tried updating my network adapter's drivers and rebooting the router to no affect. Running the troubleshoot doesn't reveal anything. My router is a TP-Link Lite N Router.

Since upgrading the OS to Windows 7 are you sure all installed drivers are Win7 compatible, and that each driver is the correct one for that device model?
Have you checked in Device Manager for any driver errors (missing or incompatible drivers will have a question-mark or exclamation-mark against them)?

You don't say if it's a full-size PC or a laptop. For laptops, you should get the wireless driver only from the laptop manufacturer since laptop's often require custom-made, modified drivers which only the laptop maker can supply (via their website).

For a full-size PC fitted with a removable wireless card, the driver is supplied by the card manufacturer if it isn't included with Windows 7.

I do stress again, all drivers must be Windows 7 compatible. Many Vista drivers will work on Win7 but there are exceptions.

Since you're now using Windows 7, please update your profile to reflect that. Thank you.

Sorry, I forgot to mention that the PC with Windows 7 is a desktop. I think I solved my problem though. Device manager didn't show anything unusual but I did notice that my router's firmware wasn't up to date so I upgraded that to the latest version and downloaded the latest drivers for my desktop's motherboard (the network adapter is built in). After that I just entered in my router's information manually for the laptop and it seems to be connecting fine now. I guess it was just a router problem then? Still funny that before, without the update, that all devices were connecting just fine until I installed Windows 7. Never figured one PC with a different OS could interfere with others trying to connect. :D

Ok, so I guess my problems aren't over. Browsing the net on a wireless connection works just fine but download speeds are really slow ranging anywhere between 2kb - 20kb/sec. I tested this on my PS3 as well just to make sure it wasn't a problem that the laptop contracted while I was trying to fix it but the same symptoms show on it too. Good browsing connectivity but horrible download rates. I don't know if this will help but here are the network settings I got from using ipconfig /all
