WiFi connection problems at random
Hi all,
Hoping for some suggestions to help fix my problem.
Set-up
- 3 x Deco M9 Plus
- Main Deco is in router mode, connected to Virgin media hub
- around 20 devices using the network, iPhones, TVs, laptops, games consoles etc
- recently upgraded to firmware 1.5.6
Problem
- seems to have started happening since I upgraded my set-up to 1.5.6. Previous versions seemed fine and now wishing I hadn't upgraded.
- seemingly at random, certain devices can no longer connect to the WiFi whilst majority of devices continue to work perfectly. Repeatedly toggling WiFi settings on the device does not do anything, nor does switching to use the guest network or rebooting the device
- I have to reboot the main Deco in order for the device to connect, which is far from ideal
- doesn't appear to be any pattern that causes this - affects different devices at different times
Ideas/What I've tried
- toggling the settings for a device to use the Mesh or not - no difference
- enabling fast roaming - no difference
- just rebooting satellite decos - no difference
- changed the DNS gateway from blank to be the main Deco ip - no difference
- running the network optimisation - no difference
- looked through the Deco logs but couldn't spot anything definite as they are far from friendly, but I suspect this is some problem with the Deco not providing IP addresses to the devices when they attempt to connect ?
- Tue Mar 15 09:38:16 2022 daemon.err udhcpd[9340]: no free IP addresses. OFFER abandoned
Has anyone else experienced this and/or have any suggestions to fix ?
Can I downgrade from this version safely ? (be great if you could do this via the app).
Thanks
