My question is this: is there a way to lower it even further? The command doesn't like negative numbers. Using a wifi analyzer on my phone, I can however tell that the signal IS weaker at 0 dBm then at the default 31 dBm, and it's definitely not interfering with the other equipment nearly as much. Actually, Wireless Local Area Networks (WLAN) are being extensively deployed in many places to provide easy access to. WiFi is a two-way street Match your transmit power levels to ensure your clients are heard by your APs. Still lets us connect to the Pi's wifi from 100 feet away, and through a wall, with full bars. To ensure equal receive levels, a WLAN pro must ensure all other things are equal System gain is always equal in both directions, so that leaves the transmit power as the only variable. The strange thing is that settings this to 0, which we can verify with: $ iw wlan0 info Lowering the tx power seems as simple as just doing: iw wlan0 set txpower fixed N 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. The Pi is running hostapd to create its own wifi network that other devices (laptops, smartphones, etc) connect to. This is a problem because it can't be removed from the box it's in, and we need its wifi enabled. The cisco AP transmitted power by default is (17 dBm / 50 mW for 2.4 GHz and 16 dBm / 40 mW for 5 GHz). We have a Pi 4 in a box with some other equipment, and it turns out that the wifi of the Pi is interfering with the other equipment.
