Deco App Causing Main Hub to Go Offline

Mine loses internet connection if I click on “internet settings” within the app. And yes it’s up to date. Only way to get the internet back is to unplug the Ethernet cord from the WAN and plug it back in. That fixes it. Also does this if any changes to DNS is made. Deco X20 v4.6 here.

Can not get USW-FLEX-2.5G-8-POE to work normally

Yes, this has been dawning on me as well, the only culprits I can think of are my Deco X20s still conducting wireless backhaul and maybe the PS5 which is configured on both WiFi and LAN. But if this would be the cause, this should have happened with my Netgear switches as well I guess. Another possi

Could my TP-Link Deco X20 system be causing persistent network disconnects on both Wi-Fi and Ethernet?

Thanks for your reply! I’ve done a bit of testing so far: My Deco system is in Router Mode (I tried Access Point Mode too, but it didn’t resolve the issue). Only the main Deco has DHCP enabled, my ISP modem is in bridge mode, so there shouldn't be overlapping DHCP from that side. The problematic mac

Yep, same issue here on Deco x20. Can pretty much reproduce it by just using the app for a bit, refreshing my network status or changing a single setting. It’s like it overloads and crashes the whole main Deco unit. If I unplug the Ethernet and plug it back in it turns green almost immediately. Pret

Quantum Fiber Constant Dropping With No Resolution

Thank you for posting this. I have been made to feel like I'm taking crazy pills. The customer service reps keep telling me they've done everything they can to diagnose the issue and everything "looks fine". The last time I called I asked them to reach out to Programming (this is the tier above the

Why the most companys are going for matter over wifi?

Yea the ones I have are in mesh, it’s the Deco X20. I do find that route quite disappointing as it can’t even separate 2.4ghz and 5Ghz, I can only turn it on and it has to have the same SSID.

Deco X20 loses app management

I recently have been unable to make changes to my deco or reboot from the app when connected to an X20. I wonder if I have the same issue? I have not been updating my firmware.
