I have a TP-Link WR841n v9 router with DD-WRT v3.0-r30880 std (11/14/16) version firmware.

I have set it up as a Wireless Access Point connected to my main router (Archer C7 v2 - latest ddwrt firmware build) via a LAN-to-LAN Ethernet cable.

I followed this guide: https://www.dd-wrt.com/wiki/index.php/Wireless_Access_Point

I have run into a number of issues and over the course of 10 hours have reached a point where I have no idea what is going wrong anymore.

In list form, priority sorted:

    There are two PCs connected (wired) to the WAP. Earlier, when it was sort-of working, they could see each other over the LAN but neither could get internet. Now the WAP just shows up as an unidentified network and screws a lot of things up (see below). Neither PC is being issues IP address by the DHCP at the primary router when implies that something is wrong with the WAP.

    The WAP doesn't receive a DHCP lease from the primary router. (Should it?)

    When the WAP is on and wired to my main PC and my main PC is also connected to the wireless signal from the primary router (weakish connection) the internet stops working.


I've started to pull my hair out over this so help would be appreciated.

There is a known bug, at least on my TL-WR841N v8, where the wired LAN ports can't communicate between each other. Your first problem and maybe others might be caused by this.

This solution works for me:
Code:
swconfig dev switch0 set enable_vlan 1
swconfig dev switch0 set apply
