Matter devices can't connect with wifi eventhough very near mesh extender, please help!

Matter Utilities Question & Feedback

I have google fiber 1gig in my office and that is where the main router is. I have a mesh extender that came with the google fiber in the living room. For the life of me I can’t get certain matter devices to connect to WiFi unless they are close to the mesh extender in the living room. I have one device in particular that can only be ran inside the house through a wall and is in the office right next to the main router and it refuses to connect in apple home even with the router inches away. I have figured out that for some reason when I have the mesh extender right next to the matter device it connects. But then when I move the mesh extender back to the living room where it needs to be and my matter device drops.

Why won’t it stay connected to the main router? What am I doing wrong here? Why will it only connect to the mesh extender and not the WiFi router itself? Hope someone can’t help me solve this issue

Matter devices are super picky.. Once it connect to something (like your extender), it just stick there. Move the extender back and your device won’t switch to the main router

Also, router vs extender might be on different 2.4GHz channels or power levels, so even right next to the router it can act weird. Extender usually gives a cleaner signal, that’s why it works there. Are you trying to check the WiFi settings on your main router, especially the 2.4GHz band. Sometimes just making the router and extender use the same channel fixes the problem, hope this help

How would I go about doing that? Any help would be appreciated

it’s going to be in your router setting, start looking at Wifi setting

for the 2.4Ghz you want a channel width of 20 and use channel 6 on one and channel 1 on the other if you can for that band. I would go with 80 for 5Ghz and pick a non busy channel around you. You can use a WiFi scanner app for that

my wifi settings are 2,4 GHz , CH 6 , 40MHz

5GHz , CH 112 , 160MHz and no problems

and i use 3 Border Router , and 1 Extender

it helps to power off all Router and Extender and end devices , then power on router , wait , then extender ,wait , then end devices.

Thanks! Your setup is pretty much the same as what the other user suggested. I changed my settings and things quite improved so it really seems like the issue was from the config

Before that, I had already tried splitting the bands so the devices only stayed on 2.4 GHz, even created a guest network and moved everything there. Still no luck. It only worked when the device was near the mesh extender, not the main router. I also tried resetting the router, extender, and all the devices, but the connection issue was still there.

I just updated the settings again and rebooted everything in the order you mentioned, and so far it seems stable. Hopefully this isn’t just a short-term fix
