My phone gets 500kbs to 1mbs download speeds by itself, but if I plug into the computer through USB, my tethering speed is only at 50kbs. Also, when I try to use Foxfi, my computer connects to the phone but with "limited access." I have motohelper 5.5 and motocast. I also have my intel wifi driver up to date. I have a Droid Razr I use speedtest.net to test my speeds I use the cable right out of the box I updated my phones system it runs android 2.3.6 anyone have any ideas?
