Didn't think this would be the problem. Could be your modem, too. And by design by provider.
I still have issues. I can get on FR (thank God) but I can't get on any homepage. I can ping any website and have a valid IP address but still there are...issues.
This has been a real learning experience for me. My "easy 30-minute setup" has consumed 2 days and 2 routers and 4 calls to various tech support.
I have more sympathy for the non-computer-literate masses now. If it's this difficult for me, it must be incomprehensible hell for dweebs.
Anyway, I feel relatively secure from neighborhood hackers. I changed the admin password, changed the router IP address, set up strong encryption, etc. Whew.
