Hello! In connection to the main problem, my Apple products (MacBook Pro and iPad) are not connecting to the second node (though they can connect to the main node) and I don't know why. Our cellphones (Andorid) have no problem connecting to both nodes. Hope you can provide some insights on how to work around this. Thank you!

I recommend the following:

• Update to the latest firmware
• Power cycle the offending mesh nodes
• Forget the network from the affected devices and reconnect
• Assign a static IP on the affected device

...what worked for me.

My Wifi wall clock dropped connection again, so I tried hard resetting which worked for me a week ago. After all the lights were working, I reconfigured the clock, but no connection. Then I power cycle, making sure to allow for a spacing of a minute in-between switching off the modem and the router. The usual recommendation is at least 30 seconds or at least a minute. But still no connection.

But my clock worked the first time the cable guy installed the Huawei modem model Echolife HG8244H and the Deco X20 right out of their boxes.

So, this time I left both devices off for a longer period, about 45 minutes after switching off the modem. And the clock came to life. No reconfiguration required.

I am keeping my fingers crossed this method works the next downtime.

This is a common problem that i am also facing. this is random and i have obseved oin windows devices . in my case i have a micrososft surface with latest wifi drivers. at times it fails to pick the dhcp ip . if i connect to another ssid (on dlink) it picks ip and connects which rules off a client specific issue. The only option is to reboot the deco which immediately fixes the issue.

@Kevin_Z what's fast roaming and does it really make a difference?

I have all my devices connected, but I'd just like to know.

Thanks.

This was too soon.

After accidentally switching off the power to the clock, I lost connection again. Tried many times without success. Turning off Antivirus was no help. It worked on my old router though.

And then I turned on "Network Optimization" under ROUTER SETTINGS of the app. Eureka!

@swiftwind I have the same problem and Im starting to get crazy with those decos. Ive got the M5s. I just bought a windows laptop and is the only freaking device that has problems with the mesh network. Ive got like 50 devices connected to them (smart bulbs, smart switches, smart lamps, cameras, ps4, macbook pro, android phone, android tablet, samsung tv) without any problem. Just the windows laptop. 
This is my setup:

- 6 M5s. 3 wired directly to my internet supplier router. 

- When I got everything plugged, both the deco and the main router start to fail, showing in chrome an error message that the network has changed (I guess my wifi is in a loop trying to find where to connect)
- When I unplugg the mesh network, my main internet router works flawlessly.
- I tried creating in the Deco app a guest network and it connects perfectly.
- Definitely there is a problem with the mesh network and windows. Havent found the answer yet, I have been in this #$@#$ like 3 days.

Your description of the problem doesn't make much sense and seems unrelated to your windows laptop problem

Open the Adapter Settings in Windows and right click the Wireless Adapter, click properties

You'll get a little properties window with a bunch of options, try disabling ipv6, or try changing some adapter settings by clicking "Configure"

@Lyam 

Thanks for your quick response. I followed your sugestions but none of them worked. :(
I have tried a lot of options but nothing solves the problem.

For example:

Updating drivers, 

Deleting my wifi card and installing again

Rebooting everything,

Changing DNS in my wifi card and also decos

What makes everything more confusing is why is it affecting my main internet router when are plugged into to it?

And also why just the guest network is working fine?

Its definitely something with my windows and the Decos. I tried connecting my laptop to another neighbor's router and works fine. 

I also created a mobile hotspot with my phone and I get good internet. (My phone is connected to the Decos)

Update. Broke again. Network Optimization does not help this time.
