I have a computer that hasn't been able to connect to the internet for a while now. I just did a fresh install of Windows 7 and installed the drivers for my wireless card. It is now able to detect networks, but it can only connect sometimes and it usually does not have the ability to connect to the internet. If it does, it is extremely slow. I noticed that when I plug the wireless card into the PCI slot, a red light turns on. I am currently using a newer, "better" wireless card, but it also does this for wireless cards that once worked with my computer.
The router is using some sort of mixed password, with a bunch of different things mixed into it (WEP, PSK, WPA, etc.), if that matters.

I think you need to sort out reception issues and wireless security (WPA etc).
Start by connecting the computer directly to the router by ethernet cable instead of wireless and see if problems go away then proceed as follows:
You should also try to optimise your reception and avoid interference.
1) raise the router above furniture level
2) Experiment with channels (some will work better or worse depending on your environment)
3) If you can detect strong neighbouring wifi, use a channel 5 stops away from strongest.
4) Relocate cordless phone base or video sender etc.
5) Be prepared to move the computer (or at least turn it so your body is not between the router signal and the wireless adapter's antenna.
