My wifi connection keeps dropping even though my mobile is only a few feet from the router, i have a full wifi signal on my mac
i have to soft reset the mobile every now and then to get the signal back on my mobile..any help please
Have you been in to settings and "forget" the wifi connection? Then just set it up again, it's worth a try.
I've just added a detailed report on my own wifi issues. Your views suggest to me that this is as i suspect a common issue. I'll try the wifi N tweak in case it helps but I doubt my 3G mifi is wifi N.
At the behest of sony support i have factory reset and repaired a device and even replaced the entire unit. They need to recognise that this is not a one off issue but a fault in their os build that needs a fix as it is spoiling an otherwise excellent tablet.
Tried...doesn't make any difference 
Hi Karin,
Have you seen my other post on this issue and tried my suggestions?
This works for me almost every time.
To help with the "how long do i wait" part of steps 2 and 4 I have an app called Wifi fixer installed. This app doesnot actually fix this issue, but if you have it on the screen when you enable airplane mode you will see it log
WIFI DISABLING
then
WIFI DISABLED
It is after the DISABLED appears that you can enable wifi in step 3
Hope this helps.
