Ubuntu Wireless Very Slow


Hi everyone,

I was running Ubuntu 10.10 and my wireless Internet was very slow (~1 minute to load a website, and downloading was excruciating). I dual boot my machine with windows 7, and I have no wireless problems at all when I am running windows. I disabled IPV6 and that did not do anything.

I recently upgraded to Ubuntu 11.04 hoping that this may fix the problem however my wireless internet is still very slow. When I plug my computer directly to my modem, I have no problems at all.

I was wondering if anyone had any ideas as to what might be making my wireless Internet so slow when I run Ubuntu?

Thanks in advance.

- try wget command on a large file and compare the speed with your web browser.
Code:
 wget http://download.fedoraproject.org/pub/fedora/linux/releases/15/Live/i686/Fedora-15-i686-Live-Desktop.iso
- monitor system activity using top while you download things. Could well be your system is paging.

- check which wireless access point you're using. Maybe when using Linux you're not on same access point.

Try to connect on ip and see if this change anything.
Verify the dns servers.
Try to set the wireless to open, no encryption.

Kind regards

Thanks for the responses. I used the wget command to get the file and was averaging ~30kb/s.

I am very new to linux (<1 month), and I am unaware of what you mean by my system might be paging, or how to check the wireless access point.


Also, I connected on ip and it was still slow. How would I verify my dns server and set wireless to no encryption?

Thanks

You can set this in the wireless router.

Kind regards
