Hello guys,
Ive looked everywere but i cant find a fix. I have a Linksys WRT54G router and a atheros AR5001X+ built in wireless card. Now my problem is, i had my wireless connection working perfectly fine. However, upgraded from windows xp home to pro and now i cant get my wireless connection going. It displays "wireless connection unavailable." I connect a LAN wire, and it works perfectly fine... is there a setting that im overlooking?

Help me out PLEASE im going insane

Remove the wireless NIC from device manager and reinstall it.

check and make sure its running on the same channel as the router.

i have reinstalled the drivers.

How do i check its running the same channel?

You don't. You only set the channel in adhoc mode. In infrastructure mode the client does a passive scan and picks up what channel the router or access point is transmitting on.

Make sure you've got the SSID set and the WEP key is entered correctly.

Well concidering the fact that the connection was working.. is there anyway i can go into that adhoc mode? Sorry guys im fairly new to this...

my ssid is set to "linksys"

and my web is set to
Default Transmit Key: 1 ??

do i have to set a passphrase? or type anything into the key1: area?

The wep key just needs to match on the client and the router. I'd set it to 64bit and enter a 10 digit hexadecimal set of characters, eg: dddeeeddde

Or just leave wep disabled if you don't fear people stealing your bandwidth.

The SSID needs to be the same on the router and the client too of course, so set the client to match the router.

im about ready to shoot myself in the head... or the laptop!

I call the place i bought my laptop form and the fuckers cant even speak proper english and they treat you like shit! "call fujitsu" i look at fujitsu's numbers... all in either japan, tiwan, korea... etc. I give up! this is to damn complicated

I have the same problem (look for the 22 dollar "Atheros" cards on Ebay, same one). I never noticed it before because I've been using Wildpackets' 3.xx drivers (don't try 4.xx, same problem apparently) the whole time and could connect to anything wireless. When I wanted superAG/superG support and Xtended Range, I realized that only real Atheros drivers (and not wildpackets) would suit. I CAN detect and connect to wireless networks with the genuine drivers, but using them, I CAN'T detect my WRT54g anymore. This pisses me off but I have a USB adaptor to connect to the AP (when I don't want to switch back to wildp. on my atheros). It's a great hacking card, assuming you can get linux to work (all above info is for XP, don't worry). If somebody finds better drivers (with functionality) let me know: markermanx5@netscape.net.

By the way, please do not post stupid suggestions like disabling WEP/WPA. The network is there! Even my dopey canary wireless detector sees it.

Here's the first posting about this on this site (they too wanted to play with WEP settings, go figure):

IF something changes just search for "Atheros"

Here's the Ebay listing for my card (won't last long, but it will be relisted under "Atheros")
