Wireless network disapeared

[metallica435435]

Hey guys, I cant believe there isnt another forum on the internet discussing this already... but My wireless network disappeared a couple minutes ago. its does this everytime i try to join a network. it fails, then disapears. Im currently on the network that Im trying to access wirelessly. I dont understand what is going on. I was having slow connections with 1 wireless card, and then i got this one, which sort of worked well (still not as well as my laptop) but semi well for about a year. are all desktop wireless cards just garbage now? i spent alot of money on this one and it cant even hold a signal for longer than 3 seconds.... it sees all the other wireless networks just fine but not mine anymore... is there some weird setting on the card that i need to change or something? ive tried resetting the router multiple times and had no luck. I dont know what to do. thanks for anything you guy might be able to provide. I hate asking for help but im gonna throw the computer out the window if this goes on for another second.

Ok, so i was wrong. There was no setting to check 300 or not 300. What I was seeing earlier was the "max rate" section in the program inSSIDer that said my max rate was 300, and I thought that was weird because all the other networks in my neighborhood were a max rate of 144. What I did find though, was a setting in the advanced section of the router that was allowing 20/40 Mhz for the channel bandwith and I switched that to a manual 20Mhz. So I think that will fix my problem! Thank you so much! That program inSSIDer is great btw, Im not sure I would have ever been able to figure this out without it or your help!
