Wi-Fi time-out while full signal.

[I-Han]

I have a question I cannot seem to figure out. A couple of months ago we got a new wifi AP from Telenet and ever since I cannot get connection about half the time. Following message pops up:
Connection with 'tele net...' failed. A time-out with the connection has occurred.
(more or less as it is a translation). At first I thought it was because of the wifi signal but I installed an app on my iphone to see the % of wifi signal and everything is ok (75%+) + all other laptops and iphone work perfectly fine on it.
I got myself an AP with 3 big antenna's and connected it to the Telenet modem with same result. Can anyone help me with this problem?

wifi timeouts

I was having the same problem after upgrading to a new wifi/router from my provider (old one did not support 802.1n).

Constant disconnects - every 5-10 minutes, could not figure out what was causing it.

Did a wifi scan, and picked up several in the area, almost all of them were running on channel 1 or 11.

went to the admin page on my unit, and changed the channel selection from 'auto' (which almost always meant channel 1) and changed it to always use channel 6.

No more dropouts.
