Iphone 5 surfs great on LTE but on wifi, slow as all get out. I understand that some people were having problems with wifi connections hanging on but my problem isn't that the phone won't stay connected, rather its dog slow. I have full signal strength at my home and a speed test shows around 12mbps (what I pay for). However, when I try to browse, update email, ect its like the phone is on dial up. I have tried putting in manual DNS servers (google) but that has not had any affect. I have also installed the new 4.0.1 ios update as well. Any suggestions?
