Does the driver install? If not, I'm stuck.
If you can't connect from your room but you can connect from the bar, there's a signal issue. Can you move and/or rotate the wireless hub, even if only a small amount? Does it make any difference? If not, continue.
The drive installs and says that it is working correctly.
The issue with the office is that it is half underground with a high window which is where my antenna is located. The source is on the roof of the building. If I stand on a chair and stick the laptop out of the window it works without the booster. However I find it easier and safer to work in the pub!
The card works OK here.
Thanks yet again everyone. It's a mystery - probably a very easy fix - we will see.
