I have a PC Dell laptop that connects to the internet just fine using an ATT gray modem.
I then disconnect the ethernet cable from the computer connect it to the proper port on the TC. Now if I try to open internet exployer on the PC again it won't connect and I get the dreaded AT password reset tool. Go thru that and it says can't fix the problem.
I have a MacBook that is used also using wireless and it has always worked before.
I get green lights on the TC but no internet light on the modem. MacBook find the TC fine so must be missing some info for the TC to get thru the modem.
I even tried connecting the TC back to the PC ethernet port using an additional ethernet cable. Still won't connect.
This is what I get when the PC is connected to the intrnet and I get ipconfig.
Shouldn't this info be inserted in the TC using AirPort Utility? I was suspect of the missing DNS info.
Thanks for any help
You need to put the TC in bridge mode. The existing modem you have is already a router.
Plug your computer into the TC.. select Internet in v5 utility or Network in v6 and choose off, bridge mode.. here it is in v5 which you can download and install on Lion.
You can then also setup wireless in the TC however you like.. I am not sure if the existing modem also has wireless.
