Region : Portugal

Model : TL-WA830RE

Hardware Version : V2

Firmware Version : 3.12.17 Build 111108 Rel.31187n

ISP :

I'm using TL-WA830RE as a range extender.
I'm sharing an internet connection with my neighbor and I use the range extender to get internet into my flat.
My neighbor router is configured on channel 13. I was able to setup the extender with the easy setup CD just fine, and started surfing the internet.

The only drawback was that I had to reboot the extender frequently since the internet connection stops working.
After the reboot I could surf the internet for some hours till I had to rebot it again.

Since this was annoying me I decided to reconfigure it again....and here the real problem started.

I have restore the extender to its factory defaults (located at System Tools) and tried to do the configuration once more.
But when configuring the extender again, when searching for the available networks, my neighbor router is not shown.

I can see lots of other rooters but just the ones that are on channels 1-11....but not the ones from channels 12-13
I have already installed the firmware available at the tp-link website...looked into all available settings.

I'm not able to identify any setting that makes the extender search for routers available on channel 13.

Help needed!!!!!
