Kubuntu 13.10 Wifi doesn't work - DHCP timeout

wireless networking kubuntu 13.10 realtek

Solution 1

This is not really an answer, it is a work-around. It seems like, as was noted already, the driver included with the kernel in 13.10 is defective. I installed kernel version 3.8.13-03081312-generic from http://kernel.ubuntu.com/~kernel-ppa/mainline/ and booted from it. My wireless is working fine now.

Edit: The driver in kernel 3.9.11-030911-generic also works, and that is what I am using now.

And yet another update: Kernel 3.12.0-031200-generic has fixed the problem.

Solution 2

I had exactly the same problem and I found a rather contrived fix: remastering the live CD. On a working Ubuntu install I installed Ubuntu Customization Kit (UCK) and I used to customize the original ISO of Kubuntu 13.10. Basically, UCK chroots in the ISO and allows you to customize it. I started UCK and asked it to give me access to a console, then I modified /etc/apt/sources.list and I added this line:

deb http://archive.ubuntu.com/ubuntu/ saucy-proposed main restricted universe multiverse

to enable the download of newest (unstable) packages. Then I ran apt-get update and apt-get dist-upgrade, which installed, among the others, plasma-nm and other networking-related packages. Then I ended the UCK session and built a new ISO. If I start my system using this customized ISO then DHCP does not timeout and apparently everything works fine.

I can put my ISO online if anyone is interested (just leave a comment, I don't want to upload 1GB if nobody is going to use it), however I urge you to create your own ISO because its simple and you don't have to trust me and assume that I didn't tamper the ISO.

Be aware that I only tested the live system and I did not run a full install. YMMV.

    I have a Realtek RTL8188CE 802.11b/g/n WiFi adapter in my computer. Today I upgraded to 13.10 and I can't connect. Before upgrading WiFi worked just fine. I can see WiFi networks, but it just gives the error "IP configuration was unavailable" when trying to connect. Other devices work just fine. I've tried deleting the configuration and remaking it multiple times, and that doesn't work.

    So, looking at syslog, it seems the DHCP request is timing out. I can connect to the network if I manually set the IP and other settings, but I don't have internet connection through Wifi yet - I think my manual configuration is a little off yet.

    Here is lspci:

    chrisn@Zircon:~$ lspci | grep WiFi

    And output from lshw -C network

    Could you try deleting the stored configurations by clicking the spanner icon in the network applet? Deleting it and reconnecting seemed to work for me. If that doesn't work, I'd try asking in #kubuntu or #kubuntu-devel on Freenode IRC. I know that shadeslayer was working on this issue.

    That may have worked for a Live CD, but on my install, it didn't work.

    I tried to compile and install it, but it didn't work. The make commands worked fine, but the instructions said you may have to modprobe some of the drivers back into the kernel. I don't think I successfully accomplished that. I might try some more, but right now I switched kernel versions, and my wifi is working properly.

    @ChrisN You may want to "practice" doing it in a virtual box so that when the kernel is updated next time you will have a way out. If you want to post the info of what failed I can try to help you
