att-uverse new, can't access internet

[jackson byers]

f16
today we switched our tv,internet,phone  to att-uverse.
Installation seemed to go smoothly.
Initial cks of internet access worked,
on both my f16 box and my wife's imac.

But that was with browsers already up from previous to changeover.

Now f16 has no internet.

Imac does have internet, after following
att rep on phone,
to somehow ( I am forgetting the steps, probably)
--click on something like wlesspanel ?
--click on 2wire397

--enter a 10digit key found on back of new modem

The att phone rep tried to be helpful on my f16, but I couldn't get anywhere.
fwiw, I am running xfce.


I have no clue,
help please

Jack
