Lately (this past few days after an update) my laptop started acting strange.
The meaning by acting strange is that:
- Ubuntu just crashes whenever I fiddle with the wlan.
- The internet has become ridiculously slow.
Using speedtest.net points out that when I'm using Ubuntu the download speed graph is very "edgy", the upload seems to be fine. On Windows though the download speed is just fine (around 50mbps, the Ubuntu test didn't get past the 1mbps).
I think it started after the latest kernel update (to
188.8.131.52 if I remember correctly).
Tried to update it again but it went even worse than it was before.
I've done a speedtest on a live cd with ubuntu 11.04(same as I have installed) And it works great, the installed version is corrupted I guess. how can I fix it?
My system is as follows:
Dual boot: Windows 7 64bit, Ubuntu 11.04 32bit Laptop: Dell E6410, i7 4 GB Ram Wireless network card: DW1520 Wireless-N Half-Mini Card
