To resolve some network issues I have reconfigured my TD-W9970 up as a modem using the 'bridge' setting.
I was not asked for username or password for new setup, configuration page shows it set as a bridge but all my LAN settings still show, my two virtual LAN settings show up, the DHCP shows up for both and show as enabled. I temporarily enabled wifi and then 10 clients showed as connected. I've no idea if they had internet access as I disabled immediately.
I am baffled, I would have thought all LAN settings would have disappeared and I would have had to re-enter login details or am I misunderstanding a 'bridge' set up?
