TP-Link TL-WR841N as Wireless Bridge

From: andrew cooke <andrew@...>

Date: Tue, 9 Feb 2016 20:15:57 -0300

This is some random wifi router I bought locally.  It's not obvious
how you can configure it as a simple pass-through wifi bridge (as
opposed to a router), but in fact it's quite easy:

* Set a password

* Disable DHCP

* Set the main network address as anything consistent.  For example a
  static IP of 1.1.1.1 with a mask of 255.255.255.0 and DNS at 8.8.8.8

* Set the LAN to be the address you want for the router

At this point things hung, so I pulled out the plug to reboot.  On
restarting it works as a simple bridge as long as no cable is
connected to the blue (WAN) ethernet port.

You may be able to skip the arbitrary WAN address, but I needed it
because it had originally auto-detected my local network and then
objected when the LAN was configured on the same subnet.

TP-Link TL-WR841N DNS TCP Bug

From: andrew cooke <andrew@...>

Date: Tue, 9 Feb 2016 20:18:00 -0300

Incidentally, the above fixes the issue that this router has with TCP
DNS requests (when a DNS request is too large for UDP the protocol
switches to TCP, which this router does not handle).

And I probably also disabled the firewall in the instructions above.
