I have the above coming tomorrow to replace my HH5 (Infinity 2 approx 80/20) then I can use another Wifi Router. Anyway wanted to know should i just plug and play or do i need to update the HG612 with any firmware before use? any info appreciated.
the modem should be plug and play if you use third party router then you need to set username to email@example.com and any password will do also needs to be set at PPPoE not A
See if you can connect to it on LAN port 2 192.168.1.1 (admin/admin) If you bought it on ebay, I would have thought it would have been sold described as either locked or unlocked.
If its locked you can't do anything with it (other than use it ), changing the firmware using the method I linked to is the unlocking process.
