I just got my S3 today and it has been great so far save for one issue. I seem to be experiencing really bad WiFi performance. I ran a speed test using the speedtest.net app on my iPhone 4 and got around 8 megabits per second down. However, when I ran the same test on my S3, I got about 1 megabit per second down consistently between numerous tests.

I don't have this issue while using LTE, which makes me think that it is a problem with the WiFi antenna. Is anyone else experiencing this issue?

Thanks

Make sure your phone is not on Power Save mode.

Try forcing the WIFI to 2.4GHZ and see if that improves things

Well, I have tested and yes you can get great speeds via the wifi, however something is quite wrong with it too, see my bug post in this subforum.

I have my wifi forced to 5GHz and just now at work I got 49ms ping 33449kbps down and 38990kbps up to a server that is ~200 miles away. Seems to be working fine to me :)

I have the same issue. It's not as fast as my s2 on WiFi.also sometimes it loses signal and the WiFi turns off by itself and then on. It's really weird

Thanks for all the suggestions. It might have just been a temporary thing because I wiped the cache on my phone using the default recovery, rebooted the phone a few times and now its fine.

I'll keep testing it to check if this issue comes back, but ad of now I'm just glad that it is working now.

That made a HUGE difference for me. From 5mbit/s to 50mbit/s downstream. THANK YOU.
