As regular reader will know (that’s not a typo, it’s a joke, but by having to explain it I’ve proved it’s not funny), when I upgraded to Ubuntu 11.10 I started having a problem with slow Wi-Fi. As I explain in my post about the upgrade, I found something which at the time I thought was a fix. It basically just enabled or disabled (I’m not sure which) an option in the wireless driver. But after I wrote that I started having problems with Ubuntu freezing, and quite often too. Now when Ubuntu crashes as many times in a week as you can remember it doing in the previous three years, you know something is very wrong. Though I admit it was only when it did it twice in one day that I took action. I undid the fix I had found, which was as simple as deleting a file, and the crashes stopped. Which was good. The problem was I was then stuck with slow wireless again. Which was bad. I decided to live with it though, I’d searched for quite a while to find the original fix, and I thought it easier to wait and see if a future update arrived to fix things properly.
After a while though, having slow internet access gets really annoying. So the other night I decided to have another look for a solution. And I think I’ve found one. Basically it involves removing NetworkManager, which is Ubuntu’s default, erm, network manager, and replacing it with Wicd, which is quite similar and, for my needs, just as good. Now that I’ve done this my wireless speeds are back to normal! If you’re reading this and have had similar problems with slow Wi-Fi since upgrading, I recommend you try Wicd. You can install it via the Synaptic Package Manager, or the Ubuntu Software Centre, or via the terminal
(sudo apt-get install wicd). After you’ve installed it you then need to remove NetworkManager. I’ll repeat that key word again: after! If you do it before you’ll be somewhat screwed, as you’ll have no way to easily connect to a network, wired or wireless, from which to download Wicd. To remove it open a terminal and enter:
sudo apt-get purge network-manager network-manager-gnome. As with any time I post anything with a
sudo command, I won’t be held responsible if things go wrong!
Now, as with many of my posts, I wrote this but didn’t publish is straight away. I like to look them over with fresh eyes before I put them “out there”, to make sure I haven’t made any silly mistakes. Well in-between me writing this and me posting it I had another crash! It must have been two weeks or so since the last one, so I’m wondering if it’s a different problem. A new kernel and new graphics drivers, among other things, have installed via the Update Manager over the last couple of days, so it could be something to do with them. Hopefully I’ll sort things out completely soon, and I’m sure to post about it when I do.
