It puzzles me everytime I see one of these threads. I find the WiFi reception on the device to be great, much better than my last handset, Desire HD. The DHD would struggle to hold a connection in the rear bedroom of my last house, which was at the opposite end of the house to the router. It was so bad I had to use Connectify.me as a bridge via my laptop! The SGS2 would hold a connection without issue, even going out into the rear garden, something my N1 could not achieve. I'm stumped as to why some people really struggle with the signal strength on WiFi.
Regards.
