Voice PE drops WiFi randomly daily

[brisk lake]

I am in a very saturated WiFi neighborhood and have to battle well over 40 different networks all on the 2.4ghz at any given time. With that said, my signal is quite strong with the router as it's just on the other side of the wall less than 1 foot away. I of course have no way of logging into the PE to check the strength. But, it tends to drop around every 5-6 hours or sometimes not at all. I know it does this because I get the white light ring while it tries to connect. I also monitor it with Uptime Kuma to send me alerts. I don't think it's a defective unit, but was curious if anyone else has experienced this in any way? I do have a network extender repeater I can put near it, but frankly, this would be overkill I think.

I may have had this issue with other 2.4ghz devices, but to be fair, none are as smart as this to show a white ring of connection! 😉 So, I'm not 100% certain it's the PE.

check dns and ip settings.. almost always dns related.

set 2.4ghz bandwidth to 20 or 40mhz, not 20-40mhz on router

Thank you for stirring my thoughts some more! My Router has been at 20mhz for quite some time: so I didnt' really think about that but it's good to know I was already there! This had me digging further since you suggested DNS so I checked my Ad Block. I use AdGuardhome on it's own LXC Server which the Voice PE travels through and the rest of my network gets filtered through, I thiink it may have been an IP conflict after all, One of my TP Link plugs had also been sitting on the same IP without my catching it during setup. It turns out that when I set up the Voice PE, it picked up an IP from my DHCP server in AdGuardHome which was not currently being used by the TP-Link plug . I went ahead and reassigned a new static IP to the Voice PE and I think it should be good. 🙂

So far, since changing the IP it, it lost it's connection one more time. I will keep an eye on it some more.

Would this happen to be due to a power adaptor? I'm thinking possibly but these are my latest logs from ESPHome:

I'm not sure why it's disabling it but it still works though in spite of the message. Additionally, the Connection reset by perr I think is about when it reboots. I had to some server reinstalls and haven't put my watcher on so it's probably been happening more. .

Is 5.10V suitable for this? (I bought a tester to check)

That was with the cable only, under load (when plugged in and idle), It ranges from 4.992 to 5.024 on average so I know it's at the minimum 5V, but what about if it goes lower to the 4.9x? Amps are well below the 2A max.

I had many random reboots today somtimes 2 or so hours apart. I dug out a spare WiFi extender and tried to factory reset the Voice PE so I could re-assign the WiFI access point to it. Even after doing the factory reset sequence it kept booting to where it was before. I was able to re-assign it though in ESPHome and so far, so good. The reboots have seemed to stop, but I'm not holding my breath until I get past 24 hours on it. For what it's worth - the extender is below the unit on a power strip so, very very little chance of it losing signal at this point! (If that's what's causing it).

could be faulty usb/psu/connection though, would not be the first1
