I purchased a Rb2011uias 2hnd router, and I am having such a difficult time getting internet through. I can connect to wifi and lan, but there is no internet access. wan is plugged in from the modem to eth 1. I have no experience in working with commercial routers, all of the other ones you just plug in and they work. What am I doing wrong? Total noob here.
Has the router default config?
Nat rule configured?
I am not sure I thought I reset everything. What is nat rule?
Firstly, congratulations on your purchase - I use one at my own home. 
Anyway, do you know if your ISP requires you to use PPPoE?
If so, you’ll need to go set that up. There’s a Quick Set wizard mode for pppoe - try that
-or-
If you want to configure pppoe manually then go into interfaces, click the blue + dropdown and choose pppoe client.
Select ether1-gateway as the “interfaces” - under the Dial Out tab, make sure Dial On Demand is not checked (so the connection tries to be always-on), Use Peer DNS and Add Default Route should both be checked. Supply the Username and Password, and the defaults should be fine for the rest.
Lastly, go through the IP > Firewall > Filter and the IP > Firewall > NAT rules and everywhere you see ether1-gateway, change it to pppoe-out1
The default configuration of the router should be fine for any dhcp-based internet connection.
If you need to specify a static IP address, then go int IP > Addresses and add your IP address to ether1-gateway interface, and set the default GW in IP > Routes
I will try that. Thanks
