Have tried all of those addresses NONY.
Are either of you from the NY market?
Level3 says that they are indeed locking out customer access to the router unless you have Signature or Business Class service.
Nontheless, you can access your TG862G to change the default password, SSID, and WPA2 PSK via a variety of ways.
First off, are you configured by TWC for Bridged mode or RoutedWithNAT?
Router Reset Method -
1. Remove the power cord and all connections from your device (including the coax cable)
2. Remove the battery
3. Configure your pc/mac with 192.168.0.10;255.255.255.0;192.168.0.1 (ipAddr, mask, default gateway) respectively.
4. Disable wi-fi on your pc/mac
5. Connect your pc/mac to one of the LAN ports
6. Attach the power cord to your router (with the battery still removed)
7. Wait ~ 60 seconds
8. Confirm that you can ping 192.168.0.1 from your pc/mac
9. Confirm that you can telnet to 192.168.0.1 (but don't log on)
10. Clear your browser cache
11. Confirm that you can connect via TLS - https: //192.168.0.1
Note that if the certificate on your router is either untrusted, expired, or both - you may have to grant explicit permission to establish the connection.
12. Report back.
