After reflashes, no internet

[goonermen]

Hey guys,

I've been trying out different roms lately like Scotts Manilla 2D and the Alltel Manilla 2D and my internet will work after the reflash but after 15 min or so I can't connect. I've tried installing the stock rom and the same thing happens after a few mins. I don't understand why the internet would suddenly stop working after a certain amount of time.

Any guesses??
