Ubuntu 11.10 SLOW wireless connection
I am new to Linux, so please spell out potential solutions. I have installed Ubuntu 11.10 as a dual boot on my Dell Inspiron 6400 laptop. My internet download speed is usually .5MB, after I shut down my internet using $ sudo /etc/init.d/networking stop which gives me errors, and oddly enough makes all my icons change, as well as greying out all open programs, and makes my logoff menu disappear BUT, when I pull the battery out, and reboot, internet goes up to about 7MB download for a while. Also, when my internet slows, ALL audio becomes garbled.. By all I mean I can close all open programs, put in an audio CD, and the music is garbled, not internet related at all. When I reboot, with faster internet, my audio works just fine as well, CDs, internet sites, system sounds etc.
When I run the script on the sticky to this forum I get 2 messages:
lo no wireless extensions.
eth0 no wireless extensions.
With doing a few things here is what I get:
