Hi peeps and wow you guys really go the extra mile to help! Ie Diego walking out of his house.
Unfortunately I am having the same problem, it found my flats router straightaway when I got back home today then my friend accidentally pressed the power button instead of the volume up and turned it off. Now it cannot find the wifi connection, it says "not in range, remembered". The tablet have been switched on and off several times since last night, so I had no problems since the initial post. At this present moment it finds my 2 neighbours wifi. It connected to my work wifi fine with no disconnections.
Im using Netgear WGR614 and I'm not sure if it is SSID or WEP because I did not set it up and I dont know how to check.
My wifi is set on never sleep policy and the mac address is 20.59.A0.06.99.92 and I use virgin broadband.
If this is a permanent issue I will have to send it back

Hope someone can shed some light on this.
P.S my flatmate used to have an android phone and he said he had the same problem and he couldnt fix it.
