Been looking for an answer to this myself. Although I'm not using a Torch I am seeing exactly the same issue on my 9300 with OS6.

When at home my BB is connected to my WiFi router - it shows up next to the carrier name at the top of screen.

When using the browser with both WiFi and Mobile Network on it is super sluggish and showing GPRS. Switch Mobile Network off and it uses just the WiFi and flies (well, as much a BB can fly at web browsing).

This isn't a WiFi signal issue as I can use both laptop and tablet at same time. I'm sure it did work at one time, showing WiFi logo and gprs as the status.

Did you get to the bottom of this?

Cheers
