Hi all,
I'm going to start off by saying (like so many others) that I'm new to linux so any advice should be in idiot format (so I'll understand).
I've spent the last week fighting with the wireless card on my laptop trying to get it to work in Fedora 8. Thanks to other threads here by people with similar issues I've had a measure of success in the fact that I can actually get the card to work...sort of. The problem I'm having now is it wont connect to my wireless network any faster than 2mb/sec even if I'm standing right next to AP. The other problem I'm having is once connected it'll drop the connection sometimes within seconds of connecting up to a few minutes of being connected. I'm wondering if due to trying so many things to get the wireless card to work that I may have screwed something up. Where do I need to look to check? I saw a thread in my many searches that mentioned blacklisting something. Does that apply to me? Oh, I originally tried to use the ndiswrapper (before I found the threads that talked about not using it). I think I was able to remove everything related to ndiswrapper, but I'm not positive. Here are some of my captures as my laptop is set up now with the wireless card partially working.

Now in my opinion the b43 broadcomm is flaky on the broadcomm chipset. many have better luck with the older bcm43xx legacy modules. But what I feel is the best is ndiswrapper since the inherit issue like rise and fall of speed. As for blacklisted this would be the ones I would blacklist. The b43, mac80211, and ssb. Then install ndiswrapper and use the windows inf driver. many post on installing ndiswrapper using yum or from source.

I'd suggest making sure you only had one driver module loaded at a time. lsmod will give you a list of the loaded modules. rmmod will remove modules you want to unload.

I posted the output of lsmod at the beginning of this thread. Which driver modules should (or shouldn't) be loaded?
I've been poking around a little more and I'm wondering if I need to add an alias in the modprob.conf file??? Bare in mind I'm not sure what that'll do (or exactly what that means), but it does go to show that reading can be dangerous to me
Here's what's in my modprob.conf file:
Quote:
alias eth0 e100
alias scsi_hostadapter libata
alias scsi_hostadapter1 ata_piix
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
options snd-intel8x0 index=0
Everything is now working fine. The only thing that's changed is the Kernel Update that recently came out. There is a wireless driver update in it. (2.6.23.14-107) This is all working through the b43 driver. No ndiswrapper is installed or in use. Yeah.

Notice the Bit Rate?!?! Whoopie!!! Seems the latest update fixed it! Also, it hasn't dropped the link yet! If I run into anything else I'll post it here.
