Belkin wireless router validating identity problem
That solved my problem temporarily (until I find a right driver or new wireless adapter that works for Ubuntu). Now remember you will need to do this to each computer that is having issues.
Forgot to mention that my phone is connected using WI-FI (also works with 3G). My wireless mode was initially 802.11b&802.11g&802.11n. Changing to just 802.11g seems to help, although my card supports 'n'. Option 2: From the router setup page Click on Channel & SSID.
However, it didnt work, until I disconnected, turned the power off my Wi Fi, unchecked the tab in the authenticate dialog box, clicked ok, then switched the Wi Fi power back on, and reconnected.
I have a laptop with a Dell D630 with Wi Fi power switch on the side.
Select the Connection Type as PPPo E and then click on Next.
Enter the Username and Password provided by ISP, then click on Apply Changes.
I am using Ubuntu 12.04 and am using a Belkin N150 wireless router to connect to the Internet.
It seems that there is a problem with using Belkin N150 wireless routers.
However, you may have to go into "view wireless networks", and then choose "change order of preferred networks" in left corner of screen.Click on Login in the upper right-hand corner of the page.The router does not ship with an administrator password, so just click on Submit. It would help if anyone can suggest ways to solve this issue on Ubuntu.This may not be a solution to the problem but it's a work around if you have an Android phone (depends on the model and carrier restrictions too). It worked great for Windows 7 but when I installed Ubuntu although it paired well, I didn't get good signal and would disconnect most of the times.
It struck to me that Android phones have tethering option.
