Perhaps I'm just fortunate, because I haven't had a signal drop out since I changed to wireless 12 months ago when I moved here. Which is perhaps strange in view of the experience of some of the posters here, 'cos when I look at the environment using the wifi signal tracker on my tablet, the area is lousy with viable signals, some of 'em unsecured.
But what intrigues me is that - even when I'm sitting still with the tab on the desk (and the router downstairs isn't moving
afaik) the signals (including mine) can change by as much as 10db in a matter of seconds.
Stange things these emf's...
