TL/DR you can probably use any 5GHz channel Raspbian lets you select. apt-get install wavemon and wavemon. But in my case, I would like my home router (which runs on a raspberry pi) to have a relative small wifi signal radius (say, a radius of 2 meters), so that you actually need to physically look for the pi home router when trying to connect to it. I do have both 5G and 2. Reception issues are caused either by insufficient signal strength or getting tangled in the channel underbrush of neighboring WiFi networks whose access points unfortunately use channels that overlap that of your network. The two wifis are in the same place and I would like the pi to connect to the one with the strongest signal. Other. To set up WiFi on your Raspberry Pi using the command line, you’ll need a compatible model, such as the Raspberry Pi 3, 4, or Zero W, which have built-in WiFi capabilities. Store information; Don’t have any Zero 2s but have several wifi connected Zeros. 05, the long awaited Raspberry Pi Zero 2W finally arrived. Right now, the wifi bubble the Pi creates is really big, giving us a far great range then we need, so the simple solution seems to be to just lower the tx power of the wifi on the Pi. My room is next to the router, ca. It says: Configuration file can include one or more network blocks, e. Load 7 more related questions Show fewer related It depends on how well designed the receiver is in your WiFi device.
