Setting up TP-Link WR841N v9.2 (300Mbps N Router) as repeater

After 2 cups of coffee and some light snacks, what can be done at 11pm when you just can’t sleep? Probably watch some movies, or in my case, powering up an old router and turn it into a repeater.

It’s a TP-Link WR841N v9.2, a 300M Wireless N Router, which is actually not a bad router, but currently sitting on the shelf after being replaced by a new one (I need a USB port, which is not exist on this one).

In summary, the steps are :

  1. Find, download, and install suitable version of the open-source DD-WRT firmware. Reference : http://greggborodaty.com/installing-dd-wrt-tp-link-tl-wr841n/
  2. The DD-WRT version for this router doesn’t provide a repeater mode. Another way is available by configuring the router as a client to the main router, and then setup a virtual interface. Reference : http://electrodisc.com/dd-wrt/atheros/repeater.htm

Voila, it’s done in less than an hour, and with stronger wifi signal in the bedroom, it’ll be a sleepless night.
