Basic settings DSL Tenda Router
With Tenda Router the access to your internet provider is quite simple. There are two possibilities if your provider requires a VLAN tag for the connection (the Telekom for example the 7): Your DSL modem inserts this tag or the router.
If the former is the case, you only need to select "normal" and then enter your access data:
If you still need to add the VLAN tag, select "Manual" and enter the 7 or the correct number for your provider in the VLAN field:
With these settings the router should connect directly to your provider.
