My son has an older Systemax AMD system that just won't work with wireless. Works great when hardwired but when using a wirelss network card or USB adapter it just doesn't work. I've tried several different typs of adapter and PCI cards and also went to different locatio0ns with different routers. After installing an adapter it will show the icon whci says not connected. But when I click on it to bring up the available wireless connections it won't show any. Says there arent any. I know better because there are at least 5 in my area. Tried the adpaters software for network management and tried letting windows manage the connection. Nothing works. WTH could it be? Win XP SP3 with all the updates.
