configuring wireless lan (TP-Link) with redhat 5.5

[bilal_jan]

hello everyone
i have Redhat 5.5 and want to configure my TP-LINK TL-WN321G 54Mbps USB Wireless Lan card with it.
when i plugged my TP-LINK TL-WN321G 54Mbps USB Wireless Lan card into my system my /sbin/lspci is

[root@localhost ~]# /sbin/lspci

any suggestion where i should start configuring with??
when i plugges this in my windows machine. it works fine

[bilal_jan]

is that too hard to answer that query

[MikeTbob]

And the output of

ifconfig

dmesg |grep -i firmware

I see several modules loading, I'm not too sure which one is the correct one yet...will do a little searching. Did you load these modules or were they loaded by default?

[bilal_jan]

i didnt load any of these modules they all get loaded by themselves.
can you please tell me wt steps shouid i take to configure my wireless lan card now.
output of ifconfig is

Is this being run in a virtual-box or something? I have very little knowledge of Wireless while running a virtual OS.
As best I can tell, this is your wireless.

TX packets:6 errors:0 dropped:0 overruns:0 carrier:0

So try this and see if it works. (fingers crossed)

i have just one OS running on my PC and that is RHEL 5.5.
i just unplugged my USB wireless Lan card (TP-LINK TL-WN321G 54Mbps) and ran the command ifconfig (it stil gives the same old output result)

secondly

[root@localhost ~]# iwlist virbr0 scan
virbr0 Interface doesn't support scanning.

About the best link I can find is for Ubuntu, hopefully you can substitute Redhat commands for the Ubuntu commands and get this thing to work. Check this thread beginning with post #11. If this stuff is too complicated, you might consider trying a different distro.

[coopstah13]

i'd like to pipe in and add that wireless support is shoddy at best for RHEL, you are better off using a distro intended for desktop user such as fedora
