Have evdo singal but doesn't work

[nofear0705]

Ok here's my problem. I have evdo signal at work but it never works. It says it's connected but does not load any internet pages. If it does it will have one quick burst when the page loads and then nothing after that. I have to force roaming and I'm tired of the slow speeds. I have evdo service at home and with the same signal strength and works great. I've called sprint and it's a lost cause. I first had the ic902 hybrid and the evdo worked great at work. Then i had the ppc-6800 Sprint mogul and that never worked. Now the touch pro and this doesn't work either. If you guys have any idea's please let me know. All sprint said was the were going to boost the evdo service in my area. But everyone else has evdo service. What's the deal
