Okay this is the first time I have ever had to ask a question as usually the Ubuntu community have answered everything already but on this occasion there are many people asking for the answer but not one good solution has become available so far so someone please help or I will have to install Windows on my sons and my girlfriends PCs and that would be a disaster as I am trying to help convince people to move from Windows.
I installed 12.04 on three computers on the same day.
- Dell Inspiron (Works Perfect)
- Toshiba Satellite
- Home built Desktop
The Dell works perfect but the other two either keep losing connection to the wireless Internet and even when they are connected they stop connecting to web sites, for some reason it searches Google fine but will not connect to web sites when a link is clicked.
So far people have recommended in other forums:
Removing network manager and installing wicd (didn't solve it)
Changing the MTU in the wireless settings (didn't solve it)
All sorts of messing about with Firefox settings (this doesn't solve it and even if it did this would leave most average PC users scratching their heads and wishing they had stuck to windows)
The problem exists on two very different machines and different wireless cards so I doubt its a driver or hardware issue, also many other Ubuntu users are having the same problem with a vast array of different machines and wireless cards.
Can someone please give a good solution to this as its going to turn a lot of people away from Ubuntu if they cannot get this sorted.
I would give some PC specs but the two machines are vastly different and the other people complaining of this problem also have very different systems all showing the same problem.
