Wireless Connection Keeps Dropping on Ubuntu 9.04

Posted on Sunday, April 26, 2009


If you have been like eagerly installed the latest distribution of Ubuntu which was available a couple of days back then welcome to the party of misbehaving wireless connections.

The Ubuntu version 9.04 was released publically on April 23rd and is called the Jaunty Jackalope. Given the cool features it was a high priority on my update list.

After I updated my wireless connection started dropping at frequent intervals of 5-10 minutes and this was enough to frustrate me. At first I thought it was due to a heavy download that I had initiated but the problem persisted even when i paused the download.

Next step was to explore the Internet to see how many other people were facing the issue. Not many but some. But, none is close to the problem that I am facing.

So this is what I did,

I changed the grub order of menu.lst to load an earlier version of the kernel to see if the problem went away. First, I loaded the

title        Ubuntu 9.04, kernel 2.6.24-16-generic version by changing the default boot order to 8

i.e in the menu.lst look at the following section and change the highlighted portion

# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
# You can specify ‘saved’ instead of a number. In this case, the default entry
# is the entry saved with the command ‘savedefault’.
# WARNING: If you are using dmraid do not use ‘savedefault’ or your
# array will desync and will not let you boot your system.
default        8

This helped the connection dropping out problem and the connection did not drop at all but the battery would not charge now 😦 and my skype would make the system crash as soon as I turned on the video.

Next, I changed the kernel version to title        Ubuntu 9.04, kernel 2.6.27-11-generic i.e by changing the default order to 2.

Again, the connection breakage frequency has gone down, the battery is charging fine, but firefox is hell slow now and is consuming a lot of memory.

So though the connection issue is resolved but there are several other things which need to be monitored to ensure that they are working fine. This reminds me of my promise last time that I made to myself that I would upgrade after at least one month of the new version, but I let it go this time 🙂 For now I am making the same promise to myself again, lets c what does 9.10, which should be called the King Kong  version have in store.
