I just upgraded to Ubuntu 11.04 on my laptop. Now, my wireless network doesn't work. I've tried everything I can think of.
My laptop is a "Lenovo 3000 C200" (serial number: "type 8922 2FU"
Can anybody help?
If you do lspci as k3lt01 mentions but with a -v after it (so do: "lspci -v" and look for "Wireless" or "Network") then it'll list all of the installed hardware. When it comes to Ubuntu I'd guess it's a driver issue which can be easy sometimes to fix.
I have the same issue, did as was asked and I have:
Code:
02:00.0 Network controller: Ralink corp. Wireless PCI Adapter RT2400 / RT2460
Subsystem: Accton Technology Corporation Device ee07
Flags: bus master, slow devsel, latency 64, IRQ 9
Memory at 24000000 (32-bit, non-prefetchable) [size=8K]
Capabilities: [40] Power Management version 2
Kernel driver in use: rt2400pci
Kernel modules: rt2400pci
Wired Network works fine, but in the Desktop under Wireless Networks it shows "device not managed". I am using a SMC EZ Connect model SMC2635W and the Link/Act light is on.
Edit:
I forgot to mention that it worked perfectly with Ubuntu 10.10, when I did the "do-release-upgrade" when it rebooted after being finished Wireless was dead.

Hi mytinytown. If you were using Debian I'd suggest you re-install the Ralink firmware but from memory (I may be wrong) Ubuntu has it in the kernel to begin with. Have you tried booting to an older kernel, the one from 10.10, and see if your wireless works with that?
OK Here comes my lack of Linux skills. How do you boot in an older kernel? Also, it might have removed those during the upgrade. I remember doing it before, but I believe I was using Fedora Core 2 when it was first released.

You should have an option to boot older kernel when you have your GRUB screen. Your latest kernel is default, on the top. Just below it couple of lines should be older kernels. It is good idea to keep 1-2 previous kernels available just in case like this.
My issue was I had some information in the /etc/network/interface file and once I removed all that, only having the auto lo info, it cleared up all issues with the wireless.
Hi Im new to this and have a similar problem i loaded 11.04 on an old dell 600m and had the wireless problem so i found an ubuntu forum with instructions to install packages and i lost my Ethernet and still don't have wireless in a terminal i typed lspci and i get these results
So first I'd recommend going into synaptic package manager and find your bcmwl kernel source package that is installed and completely uninstall it. Then install the package I listed above. If you don't have internet on that machine simply download it somewhere else and then transfer it via USB and double click it.
You may need to reboot, and you may also need to go into 'additional drivers' and activate it and reboot again before it actually works.
I don't know what the specific problem is. I just know that my broadcom devices wouldn't work, and from searching around I saw that many others had this same problem. The solution was just to use the older package from Ubuntu 10.10.
