Wireless setup in RHES 5
 
Hi;

I'm new enough to Linux to be flustered by this, but familiar enough that I think I can follow any well-written instructions.

That said, here goes:

I'm attempting to configure my wireless after having installed RHEL 5 on my laptop. I've got ndiswrapper installed, I have the correct drivers for my device (the .inf and .sys files), and in theory I know the steps to get this done.

One problem I seem to be having, though, is that I can't blacklist the default drivers for my device, so the ndiswrapper version isn't being detected at all. Everywhere I look I'm told to just add the line
Code:
blacklist <driver>
to /etc/modprobe.d/blacklist, and then reboot.

After doing so, I should not be able to find my device in the network configuration menu at all - correct?

Yet, I do.

Any ideas?

Hi Ragnarok_Sunset, Welcome to lq. Try this instead edit /etc/modprobe.conf with the following.
Code:
alias <driver> off
Good luck. ;-)

I'm afraid that didn't work at all.

I've tried various things to no avail, including adding the following to modprobe.conf:

Code:
install ndiswrapper /sbin/modprobe --ignore-install ndiswrapper && {loadndiswrapper 14E4:4318 /etc/ndiswrapper/<device>.sys /etc/ndiswrapper/<device>.inf;}
I've also created the ifcfg-wlan0 file from scratch, setting various parameters as they ought to be for my system (particularly, ESSID, MODE, KEY are set correctly).

I'm at a loss. Strangely, at one point I did have the wireless "functioning" and detecting various access points, but I could not actually connect to the internet via any of these. I have no idea what I had done to at least get that far, since any attempt to retrace my steps has turned up nothing.

For the heck of it, here is the basic outline of what I'm doing:

1. I'm starting with a fresh install of RHEL5.

2. I'm running make install in the directory containing my ndiswrapper source (version 1.52).

3. I have the right drivers, and I use ndiswrapper -i to install them. Doing ndiswrapper -l shows they are installed, and that there are alternate drivers as well which I suspect are causing some of my problems.

4. I do ndiswrapper -m, which adds a line to /etc/mdoprobe.conf: alias wlan0 ndiswrapper.

5. dmesg | grep ndiswrapper shows no love. Lines indicating ndiswrapper is being loaded, but that's it - nothing about the mac address or anything one would expect, and grepping for wlan0 turns up nothing at all.

6. iwconfig shows eth1 (the default alias of my wireless card) is sort of half-assedly set up; my OS does detect my card, and knows what make it is, but the default drivers accomplish nothing. wlan0 does not show up in the list at all.

7. iwlist scan fails utterly.

8. As mentioned, I can't blacklist, alias off, or even rmmod or modprobe -r the default drivers. lsmod | grep <driver> always shows the default drivers are loaded.

I have no idea what else there is left to try. If there is other information that may help, do let me know and I'll try to provide it.

Peacedog 05-08-2008 05:26 AM
It would help to know the card and drivers in question. Post the output from the following please.
Code:
/sbin/lspci -v
/sbin/lsmod
/sbin/iwconfig
/sbin/iwlist scan
Good luck ;-)

Sorry to have let this fall to the wayside - I've got three jobs this Summer that I've had to do running around for lately!

Anyway, the outputs of the requested commands are as follows; they pretty much corroborate what I said in plain English before. What I believe to be the relevant entries in the outputs are in bold italics. I hope there's some information in here that can help someone diagnose what is going on!

Regarding lsmod, remember this is output after attempting to blacklist the bcm43xx module by editing /etc/modprobe.d/blacklist.

Reading from here, try this.
Code:
ndiswrapper -e driver_name
Are you certain the changes were saved to the appropriate files?
Code:
cat /etc/modprobe.d/blacklist
cat /etc/modprobe.conf
Good luck. ;-)

anon102 05-15-2008 03:33 PM
Well, a bit of success has been had. I write now from my root profile, where the wireless now connects to my local internet node with no troubles.

However, I have to set everything up manually when I log in, by doing

Code:
modprobe -r bcm43xx
modprobe -r ndiswrapper
modprobe ndiswrapper
after which things are fine.

Now, I imagine there's some kind of configuration file that I need to edit so that this is done automatically, both for root and for other accounts I set up (currently I can't access modprobe or ndiswrapper under what will be my primary work login).

If that's the case, which is it and how must I edit it?

EDIT: Also, yes, the /etc/modprobe.d/blacklist file retains the change I made, but it clearly does not actually blacklist the right module. Is there an entry to /etc/modprobe.conf I ought to be making as well?

Peacedog 05-15-2008 06:28 PM
What does lsmod look like after you modprobe -r bcm43xx and before you remove and reinsert the ndiswrapper module, then again after you reinsert the ndiswrapper module? Perhaps there are a couple of other modules that need to be blacklisted.
Good luck. ;-)
