Internet problems on the ZT180

[Big wade]

I have a zt 180 running Android 2.1. About 2 mounths ago I had to flash it and it has worked well untill this week. The built in browser was not connecting even though the internet was connected and had a strong signal. It would download from the app market so I downloaded the mini Opera browser and it worked great last 2 days but now neither browser will connect to the internet. Everything else works fine. Any suggestions?
Thanks

Oh here it what it says under about device:
Model zt180 firmware -2.1 update 1 kernal 2.6.32.9

The browser that came with it and Opera browser will not work. The market does and so does Youtube. I have a weather and news widget and it works. So this is why I am puzzled/
Thanks
