Rachio keeps dropping WiFi

post by gaustin on Aug 27, 2025

I have owned my controller since 2019 and have not encountered any significant problems until this spring. I am uncertain whether an application update or some other modification has caused a new issue. I have not altered my WiFi network, so I am unsure of the cause. The device consistently freezes on the second light each day, necessitating a manual reset of the controller to restore the connection. This situation is extremely frustrating, especially when I am traveling and unable to monitor the status of my controller. Any thoughts or suggestions welcome.

@gaustin - can you describe your WiFi environment? Does the networking equipment get updates automatically from the manufacturer?

That’s the same problem I was having. It was caused by a neighbors router using the same 2.4ghz channel and being much closer to my controller than my router. I RF shielded my controller and changed the channel on my router. Been solid all summer. RF shielding fixed offline problem

Thanks @millie I will take a look at this. Seems plausible since I see this messages like it’s connected to an unnamed WiFi network.

Personally, I like IoT things on 2.4. Most need very little bandwidth, and 2.4 has a better, longer, more stable range, but lower speed potential. That longer range can cause signal interference with neighboring AP’s. Newer more powerful radios are blasting out incredibly strong signals to allow a single AP to cover a whole house, but that sometimes just clogs up the airways.

There are a number of wifi analyzer apps you can download to check the congestion in the airways, and like @millie said, change the channel on your 2.4 to one of the less congested channels.

@tmcgahey, I do have the controller connected to my 2.4 network and I did download that app @millie mentioned but that’s where knowledge ends….lol

My router has a channel scan feature. One uses this to scan the environment and let the router choose its channels. In theory it will select the less used/powerful ones.

As others said one can download a phone app that will scan for wifi signals It will provide details so that you can make channel decisions.

@millie, I changed it to channel 11 but it appears that it toggled back to auto at some point already. I switched it back to 11.

I’m still having the same issue but I know it does connect to the Wifi off and on b/c the rain is updating.

This seems like an issue:

Looks like the controller is power cycling everyday. Any suggestion to troubleshoot this?

If its any consolation on the wifi issue, I doubt its channel related. My controller disconnects from wifi a lot at random and I’ve done every possible thing to try and fix it over the past few years and it still disconnects. Seems like a poorly performing wifi adapter. Wish they had an ethernet module option.

I would contact support first for that power issue. The power cycling could just be a faulty power supply. You may be in luck, because that is probably what’s causing your wifi problem. If you have a volt meter you could check it to see if its output is what it should be.

Trying to get my system up this spring and I have had endless connection issues. No matter what I do, my Rachio2 won’t hold a connection. And why can’t we just enter a network and password to establish a connection instead of going through the very problematic connection “wizard”?! I have had Rachio since the very earliest days and it has always been rock solid.

ENSHITIFICATION has hit Rachio!
