I'm very naive to the ways of Ubuntu. My problem is that no matter which release i use, my wifi connection is very slow (can't stream anything, pages load slowly, etc.). However, when plugged into the router the speed is very fast/as it should be.

May be to do with your graphics adapter, and its drivers, if you have one please list it, and as many details as possible. – kris2340k Jan 9 '14 at 19:55
not sure if above edit is what you meant. if not, is there a cmd i can use to get the exact info that might help? – user233824 Jan 9 '14 at 20:18
after entering first cmd it returned as "sudo aptitude install ndiswrapper-common ndiswrapper-modules-1.9 ndiswrapper-utils-1.9 sudo: aptitude: command not found". Also, on cmd #2 how do i know what my windows driver is ("your driver")? – user233824 Jan 9 '14 at 20:34

Use Windows drivers yo solve your problem:

Install ndiswrapper

sudo install ndiswrapper-common ndiswrapper-modules-1.9 ndiswrapper-utils-1.9

Install the WiFi driver (from Windows):

sudo ndiswrapper -i yourdriver.inf

Check the driver is working:

sudo ndiswrapper -l

Load the module:

sudo depmod -a

sudo modprobe ndiswrapper

Configure modprobe so that it loads ndiswrapper:

sudo ndiswrapper -m

Edit the modules to add ndiswrapper at the end:

sudo gedit /etc/modules

Remember to add ndiswrapper at the end.

Hope you now have your WiFi back to max speed!

Thank you for your help: First cmd returns "sudo: aptitude: command not found". Also, on cmd #2 how do i know what my windows driver is ("your driver")? – user233824 Jan 9 '14 at 20:39
Your windows driver you must go to the support page of your computer download it and get the inf file, take out aptitude sorry. – Brask Jan 9 '14 at 20:46
No idea why this had a -1 score. This is almost exactly what I did and it worked. You do have to supply the *.inf file (and possibly the corresponding *.sys file in the same directory). – jvriesem Sep 17 '15 at 5:15

Try getting inside the router configuration page (usually in any browser such as Firefox) and entering the username and password as router administrator. Once in, then change the frequency channel / network channel. Most of the time changing channel solves speed issues.
