Wireless signal strength variability


Wireless signal strength variability

I think it may be interesting for readers to know that the following graph shows wireless signal strength over a period of 90 seconds as measured from a laptop positioned 2 metres from a router in the same room using the 2.4 GHz frequency band. This is why a wired Ethernet connection is preferable where consistent connection strength is required.

The red line indicates my connection and the other lines come from my neighbours' routers. Note that the brown line would cause huge interference for me if both were on the same frequency/channel as is often the case by default.
