Firstly,are u on gingerbread? If yes then i think u would be better off getting a new browser. i had the same problem with the stock browser.i currently use the opera mini as it is really fast.

 

are you referring to o2 mobile internet or wifi? are you connected to o2 Edge or 3G? (what data icon do you see in your status bar beside the signal)?

 

I have the same issue with 02 mobile internet Jamee411 but no clue why either.

 

The icon shows in the notification bar.

"E" stands for edge.
"3G" Stands for 3G
"H+" stands for HSPDA or 3.5G

Up and down arrow indicates uploads and downloads. Lit up usually means active. Also H+ usually appears when there is download and upload activity and that speed is available.

 

if you are getting a "G", you're connected to standard o2 GPRS internet, which is the slowest you can get. o2 maybe doesn't have good mobile internet coverage in your area. have a look at O2 | Network Coverage | Coverage Checker

 

I mainly only have G as the reception is poor in NI but my GS2 fails to connect in locations that my previous Symbian phone would connect to the internet. For me, my new faster, more powerful phone has taken me backwards & its very frustrating.
