messed up internet connection??

[Sylvia]

have you tried seeing if you can connect to the internet from one of your computers directly through the Clear 4G wireless modem? That is, skip the wifi router to see if the problem is the wifi router or the modem.

I was looking on the internet and it looks like Clear 4G has a modem with wifi built in.

Is this the modem you are using? If not, you might try this modem then you shouldn't need the wifi router.
