wi-fi weirdness

Postposted on Mon May 16, 2011 10:22 pm

So I recently got my lovely ThinkPad. W520 Trying to cut costs a bit, I skimped on the Wi-Fi adapter and only got the ThinkPad option as opposed to an Intel option. Unfortunately, the Realtek 8188CE chipset used has terrible Linux support. After a few tries I finally found the driver in the openSUSE repositories. I have it installed now, but am not viewing any wireless networks, no matter my distance from the router. When I say not viewing, I mean I have opened knetworkmanager, and hit scan and not found any networks. The hardware switch is in the correct position, but just to be sure I've tested it in both spots it can be in. Sitll doesn't work. Any insight on this? (And yeah, I've tried compiling the driver from Realtek straight into the kernel. Didn't work out too well...)

Lots of asterisks, I know. Just ask if you need any further information. Any help would be appreciated as I really prefer Linux to Windows for daily use.

So just now as I restarted my laptop to switch from openSUSE to Windows I noticed a line saying something along the lines of "modem-something or other: driver not whitelisted."
Is the firewall a plausible reason for my problem?

That's not a firewall - probably the driver's not whitelisted because it's known to be buggy, so the kernel doesn't load it unless you force it to. Since it says modem, I'd guess that's for an actual dial-up modem (does yours have one?) and not your wireless.

What I'd do in your case is buy an Intel wireless card and replace the Realtek. Newegg's got a new-in-box 6200 for $21 plus $6 shipping:

This is going to sound odd, but me and OpenSuse and wifi have a long history of hatred with one another. Before buying anything try installing Ubuntu first and give that a whirl.

Have you checked dmesg to to see if the driver is loading. There should be two eth connections.
