Hello,
I've been trying to get my DSL-320B dsl modem to connect to a broandband router I bought (Tenda W311R). I want to use the W311R in a switch and wi-fi AP capacity.
However when I try to connect to the internet it keeps returning me to the homepage of the router or in the case of the phone I get access denied on the dolphin page.
You need to properly configure the your Tenda router.
Yes, DSL-320B can be configure as router and bridge:
Go to web interface (DSL-320B),
backup your setting and switch to bridge (QUICK SETUP Wizard or ADSL Setup Menu)
To switch it back from bridge mode to router you need to reset the settings ("pin hole" on the back )
