Do you have to keep resetting your router to restore your internet connection?
Wireless routers use a specific bandwidth or pool of channels. If you switch to a different bandwidth (ie from 2.4 GHz to 5GHz) you get a new set of channels to choose from. The 2.4GHz bandwidth is currently a very busy bandwidth. Many home wireless devices use 2.4GHz; even your CMP smart meter is on the 2.4GHz band.
On the 2.4GHz band, channels 1, 6, and 11 are the most frequently used. Since these channels do not overlap bandwidth, they are less likely to cause interference. On the 5GHz band, channels are further apart and therefore are less likely to suffer from interference.
If you have tried changing your channel and tried changing your band and you are still having problems. You can try updating the software running your router, the router’s firmware. This software is not automatically updated. You will need to login to your router and do a manual update.
