Hi i just bought the galaxy s2 gt-i9100 .. it is runing the KE4 .. i dont know if its only mine .. but the wiki reception is very weak .. the internet router is inside my room .. with the phone close to the wi-fi router .. the signal varies alot .. and almost never get full signal strenght ... and my notebook get hight signal on the entire house... is it my phone ? or the phones wi-fi are all weak like this ?
With my wifes HTC desire and my SGS2, the wifi is identical. My laptop is better but its always going to be, you can't compare it to a phone IMHO. I have no complaints about the wi fi on the SGS2, if I am in the same room as my router, its on full bars. There are alot of factors when trying to get wi fi signals etc.... no cordless telephones nearby? or the like.
I would suggest that it's the early KE firmware to blame for mis-representing the signal strength. See here:- Samsung Galaxy S2 Slow Wi-Fi / Low Signal Strength | John Tankard's Web Blog My signal on KH3 "appears" to be stronger than my early firmware.
