Hi, Using the stock firmware, this is not possible. If I select this channel, the wireless clients don't connect. Also, sometimes, I'm experiencing connection drops (the router disconnects from internet), a unstable signal (even using 20mhz) and a long time to reconnect. There is one small issue with the web interface, if I change any option, the router disconnects and takes many minutes do connect again. I tried the DD-WRT firmware (many versions) and found it very problematic. In some builds, the router don't connect do the net, in others the clients run at very low speed (around 30kbs) and stability. All this problems are common to this router model? Or, maybe, the fact it's refurbished is leading to all this? Thank you.
