In our home, we have a couple laptops and other devices (ipad, two samsung phones, wii) connected to a Netgear Wi-Fi router. We live in the top flat, with three flats under us, and with flats on both sides. At the time of writing, I can see 10 wi-fi networks, but there are atleast 6-7 more that are occationally in range. Our own network naturally has the strongest signal, with the router placed high up in the living room.
For a while now, one of the laptops has had problems with the wi-fi, but only parts of the day. It will work fine most of the day, and in the evening it will start to go bad until it's almost impossible to connect. At the same time, the phones, the ipad and the other laptop works fine.
The laptop with the problem is an Asus N56DP. while the other laptop is a Lenovo W530. We have had problems with the Asus when running Windows 8, but also when running Lubuntu Linux from a USB-stick (Booting Lubuntu from USB to make sure it's not a windows driver issue).
My suspicion is that the Asus for some reason is being hit by interference from something the neighbours turn on when they get home from work (TV, computer ?), but how can I track it down or more importantly, work around the problem?
It would also help if anyone can shed light on why the Asus has problems while the Lenovo never has an issue, while connected to the same AP?
The router was running with auto-select of best channel, and has also been set to use channel 7 which was given as best alternative by the Android App Wifi Analyzer. When in auto-mode, it looked to be selecting channel 11, which is shared with atleast 4 other networks in range. Channel 7 seems to be clear from direct competition with other networks.
I'm unsure if the router actually supports Wireless N, it only allows selecting the modes: "Up to 54 Mbps", "Up to 65 Mbps" or "Up to 150 Mbps" (I've selected the last one).
The router claims to be a Netgear WNR1000v2 according the the admin interface.
