Thus recommendation #1 - Use 5GHz only.
5GHz propagation across walls is much worse than 2.4GHz propagation, therefore only nearby neighbors may interfere with your access point, and on 5GHz there are enough non-overlapping channels to choose an alternate channel avoiding this interference completely.
- xvf22 6y agoThere really aren't when you have 2x80Mhz on either side of you leaving only DFS which can be tricky since a lot of older consumer routers didn't support it. WiFi 6E should help as the allocation is massive with less propagation.
- samMouret 6y ago160MHz channels are a rarity even today, neither the latest Samsung S10 nor the latest iPhone support 160MHz. Much more common is 80MHz channel, and even then, there is a distinction between the "main" 40MHz and the "secondary" 40MHz sub-channel. If you monitor the packets over the air, you'll notice that the secondary channel is much less occupied - all mobile devices switch to 40MHz to save considerable power, unless downloading a big file. In the US, there are 6 available 80MHz channels, which is more than needed (think 4-color graph coloring).
