Problem description:
Ever since I got my Unifi, I try to use my Samsung Galaxy S2 to connect via wifi. The phone is connected but the line is really slow, to a point I cant surf google webpage. I tried it on my neighbour (Which is Streamyx) there is no problem at all. Is there a Unifi setting I should tweak? I tried calling Unifi, but they say it is my phone problem, even though I told them I tried it on my neighbour's streamyx that there is no problem. Even on public wifi like starbucks, my s2 had no prob, just my home's unifi.

I have even try to change "Band Width from 20 to 20/40. Did not work.
Change some channels, not working as well.

Help!!!!! ><"
