WiFi reliability

[jsalsburg]

I have discovered something new. For months I have been having trouble with WiFi connectivity. I errantly attributed it to being awash in WiFi Access Points nearby; more than 100. I operate 2 Access Points, one on my Cable Modem and another across the apartment for the Allsky Camera on the front porch. Yesterday I was frustrated that my connectivity was so flaky. Out of sheer desperation, I restarted everything several times. To my amazement, connectivity returned as it should with low stutter. However, this shifts many of the IP Addresses, DHCP is necessary for my setup since some of my WiFi devices must uses Dynamic IP Addressing so I cannot turn off the DHCP Service in my router.
Perhaps I should do this power/off/on/off/on thing often.

It's like rebooting in Windows - it often works after that but doesn't address the underlying problem, which almost always comes back.

Let's hope it doesn't in your case.

Thanks for the update.

A couple of things with WiFi I have experienced with the Pi (pi4 and 5) at various points.

1. Wifi power saving needs to be turned off, otherwise my Pi would fall off the network after while
2. I have very strong wifi system with Wifi 6E mesh nodes and the Pi would default to 2.4GHz on a shared 2.4g and 5g SSID. Even if my mesh was set to steer it to 5GHz after initial connection.
3. For some reason the Wifi frequency band was wrong for my location in the US. So if my mesh (which I can not set channels on) was on these bands, the Pi wouldn't connect.
4. I have around ~160 IP devices on my home network and I use Pi hole with bind9 for DNS as well as the Pihole's dnsmasq for DHCP. Assigning static DHCP reservations based on MAC addresses are you friend so that you don't lose your DHCP clients after an IP change. Pihole makes it super easy to manage this with a GUI.

Freeland Jay Salsburg ***@***.*** <https://www.youtube.com/channel/UCGczWwysaexXMO5rgn-hBDw> My RPi's WifI is turned off. I have a Bridge WiFi Router outside for it to an access point just 6 feet away. My dilemma is that I cannot have ethernet outside, I must use WiFi. The connectivity failure seems to be with the WiFi technology, that it breaks down over time but appears to renew itself upon cycling power to the routers.
