I have the galaxy s 2 i9100 and android 2.3.5 for 4 months.
From the first moment i sensed that the wifi speeds are low.
comapring to pc (lan) or laptop (wifi) there is 4 Mbps difference.
12Mbs pc/laptop camparing to 8Mbps on galaxy s 2 .
But the upload speed is the same (1000Kbps)
That is exactly as your results "gbswales"
Also , this result has nothing to do with my internet home carrier.
I also did the following test . I turned the home internet off, and operated the galaxy s 2 on router mode. (with no 3g or 4g internet) this way there is only the wifi network that created by the galaxy s 2 . When downloading a file with kies to the phone , speed is low . about 2.5 MBps .
This test does not indicate anything about the wifi problem .... i am comparing with you people to confirm.
According to all these results I would gamble on a driver problem.
I hope it is fixed in android 4 .
I also upgraded from android 2.3.3 to 2.3.5 and installed an original samsung localized rom (at samsung labs) . and the issue remains .
Also, there is nothing wrong with the wifi bars ,And i am 1 meter from the wifi router.
I have not yet figured out how to contact samsung headquarters about this .
I dont understand "gbswales" how can an internet supplier (especially the cable based) can
interfere with the speed of one device and not the other one ?
Also, if you insist , i have another carrier sim . When i switched to it the problem remains .
This is not logical because the 3g/4g connection is off in the phone for both carriers .
One carrier is not a sim card for my country . It is only when i am abroad .
I turned the cellular reception off (fight mode and then wifi on ) : the issue remains .
All that has been said about Wifi reception , Nothing has been said about cellular reception (bars) Which are very low . As you know : when bars are low : the phone increase its cellular radio in attempt to get more bars .
There is a small antenna connector above the sd card slot. I am trying to get a small connector + wire for this connector ... anyone have any ideas ?
I have seen a yotube video when someone puts a pin in that hole and the cellular bars go up. .. i cant find it now .
