Here's a new one for me..
Friend has Netgear wireless router, laptop downstairs, works OK.
Then...not works, no wireless network avail etc. Router/modem OK on ethernet cable tho'.
I make sure laptop drivers OK, I check his laptop in my house wirelessly, OK.
Still no work in his house.
Check his router with my laptop, no signal..
So before he buys a new router, I take mine and plug it in (in his room),
Now my laptop says no network.....
All still works perfectly in my house..
So - is he being jammed/blocked? -it's a detached house in a rural location, however there is a rumour that a neighbour 200yds away had a lot of BT Business vans around some time ago.
