If anyone can help I think it is connected to the Dell wireless adapter and that it might turn itself off at boot - whatever that means! Have read numerous other Dell users having wireless problems, same as mine.
Someone said about going into wireless settings and changing it so its on not off. (Not pressing the F2 button a bit more complicated than that.)
This makes sense cos I spent ages doing all sorts on Monday and it worked fine, my friend went to use it yesterday and its lost connection again and so when I went to investigate today I could not got get a connection at all.
Anyone with experience of Dell problems which they can share, much appreciated!
