Ok first post right out of the box, all of my project notes will be posted here.
I stumbled across something that grabbed my attention and totally forgot what I was actually looking for. It seems there’s an open source firmware that can be uploaded to make that $60 router /wireless router into a $600 router.
DD-WRT is a third party developed firmware released under the terms of the GPL for many ieee802.11a/b/g/h/n wireless routers based on a Broadcom or Atheros chip reference design.
If you have a look in there online shop you can check out the products that they are featuring, like the Gateworks Cambria Platform GW2358-4 which is not the smallest, but most powerful wireless unit on the market.
When I start on this project I will post my findings here along with config and Tx output power.
