Intermittent WiFi signal

I experienced a intermittent WiFi signal lately on multiple devices. Since I haven’t touched my router configuration for a while it had to be something different. Some time passed before I realized it could be a neighbor who was using the same frequency I was using. Looking into my router configuration it turned out I was using a fixed frequency (2462).  Below are the frequencies that can be configured.

[code]
Channel 1 : 2412 Mhz 11g
Channel 2 : 2417 Mhz 11g
Channel 3 : 2422 Mhz 11g
Channel 4 : 2427 Mhz 11g
Channel 5 : 2432 Mhz 11g
Channel 6 : 2437* Mhz 11g
Channel 7 : 2442 Mhz 11g
Channel 8 : 2447 Mhz 11g
Channel 9 : 2452 Mhz 11g
Channel 10 : 2457 Mhz 11g
Channel 11 : 2462 Mhz 11g
Channel 12 : 2467 Mhz 11g
Channel 13 : 2472 Mhz 11g
[/code]

While thinking about which new frequency to choose I figured out there is an option to choose the least congested. That’s what I need in an area where there are at least 30+ different access-points.

[code]
router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
router(config)#interface Dot11Radio0
router(config-if)#channel 2457
router(config-if)# channel ?
<1-2472>         One of: 1 2 3 4 5 6 7 8 9 10 11 12 13 2412 2417 2422 2427
2432 2437 2442 2447 2452 2457 2462 2467 2472
least-congested  Scan for best frequency

router(config-if)# channel least-congested
router(config-if)#end
[/code]

Now every WiFi enabled device in the house is happy again.
