Samsung S Galaxy II (i9100): Problems with Wifi signal, bad reception, breaking connection I recently bought an Samsung S Galaxy II (i9100), and I am pretty pleased with it. It is by far the best phone I ever owned. 

The only downside I have is that it has a really poor wifi signal. It gets almost half of the bars my old HTC HD2 got. This is not a big problem, I am not always far away from my router anyways.

The really annoying part is that is stops working after a few minutes. I am just browsing, and then suddenly the connection stops. I then need to switch off wifi, and back on the get the connection going again.

The signal is already on 'never sleep', so that is not the problem. And I do not have this problem with the HTC HD2, so it's not my router either, its just the phone.

Anyone know a fix for this, I have been looking on the net, a lot of people have this problem, but I failed in finding a good solution. 

Really bad downside for such a great phone.

----- EDIT -------------

I also read an article about it maybe being the router. I downloaded a program called Wifi-Analizer. It said the channel had a poor signal, so I changed the wifi channel to 13. I also changed the settings to use N only, before it was B + G + N. 

This helped a little bit at first, it does not break so often anymore, but the signal does break every few hours.
this looks like a problem with your phone, because I know many S2 owners who have not had this problem. It is better you get the phone to your dealer and have it repaired or just try a factory reset, you might have installed an app that messed with the system files. All this is assuming your router is fine!
