Bushfiva, Many thanks. I looked at this page and downloaded one but it didn't work. I am not very technical. Which one do you think I need?
I have just removed the driver which my computer thought that I needed it was: 'RTL818SE Wireless Lan Driver'
Thanks also for your advise Mike, but it was working fine on my other computer it is just a case of getting the correct driver, I am sure. The current hardware was not cheap and in this location takes weeks to arrive. I need to sort the problem out very fast.
