The apartment I live in has a single corridor opening into rooms A,B,C,D adjacent to each other. The WAN ethernet terminates in room C where I have a Netgear WGR614v7 router installed. This router has a hidden SSID broadcasting on Channel 2 in g band only. The laptop in room D with a 802.11n adapter can see the router clearly. So far so good.
In come a couple of new mobile devices, mostly used in room A. The signal is very weak so I get an Asus RT-N12 b/g/n router, place it in A, and set it up as a wireless repeater via the switch at the back. So the devices in room A are happy. However, the laptop now starts intermittently losing net connectivity but not the WiFi signal. In the connections list, the connected SSID shows radio properties as '802.11gn' which leads me to believe that the laptop is connecting to the router in A, despite the g router being nearer, and that results in some signal confusion. Switching off the 'A' router resolves the issue.
How can I make use of the repeater and yet avoid this problem? The laptop is using Win7/32.
