I just received my htc evo v about two weeks ago. The first week I had no issues with my data connection and on speed test on 3G, I was getting between 1 - 2 MB download. Week two, I changed these wimax settings and around this same time going forward, my 3 G speeds are horrible, I have consistantly been getting network issues on trying to connect to the internet. I called virgin mobil and they said that there shouldnt be any network issues in my area. They also said that wimax is not available in my area. What I was wondering is that, changing these wimax settings, would this in any way affect my 3G connection or speed? Thank you for your feedback. I was thinking about changing back to stock settings but I will wait for feedback. Thanks.
