Hi everyone, first post here. Might be quite a long one - hope that's ok.I'm at my wits end with my CPE Pro on an unlimited 5G plan with Three. In a nutshell, the internet connection drops out at least once a day and all my devices, wired or otherwise, lose access to the internet. It seems that the only way to restore the connection is to physically unplug the router and plug it back in - rebooting via the AI Life app doesn't work, it comes back with no internet connection. At other times the ping goes sky high - 1000-4000ms - while the transfer rate drops to almost nothing. Sometimes it recovers, other times it doesn't. This might just be variations in my reception - I'm on the edge of the stated 5G zone and technically not covered (I had to beg Three to give me the contract to start with) - but 5G reception is showing as good, all three lights are on, and transfer speeds, when they work, are high.I've spent what seems like hours going through the router settings trying to find something that might be causing the dropouts, but nothing seems to help, but there's a few things that I don't understand and can't seem to fix. These are shown by some odd messages in the router log. The one that's most concerning is this one:2022-01-25 16:02:44System WarningLAN side maintenance IP address 192.168.11.1 conflict with Device 54:**:**:5b:**:6dThis appears in the log multiple times a day, and may coincide with the timings of the drop outs but I'm not 100% sure about this. Concerningly, 192.168.11.1 is the router's own IP address, and the gateway that all my devices use to access the internet. The MAC address mentioned in this log entry belongs to my wife's Oppo Find X3 Neo phone - I have set the phone to use the Device MAC address on our home network, and have given it a fixed IP address in the Huawei. The phone reports that it is using the fixed IP address I have given it... so why is there this scary conflict and is there any way I can resolve it?There is also occasionally error messages in the log saying that "sync time failed from BBOU" - I've tried changing the time servers but that doesn't help. Might this cause the dropouts?The other thing I've read about is that there might be IPv6 issues that can cause dropouts. I've seen that these can potentially be fixed by adding an APN profile, but I cannot see where to do this. The Network Settings page in the router looks like this for me:Nowhere I can set APN profiles, no IPv4/v6 options, nothing. Is this because of Three's locked firmware? And is there any way I can get around this?The other thing is that I have devices plugged into both ethernet ports on the router. One is a passive switch with a few wired devices (an Intel NUC PC, an AVR, a Blu-Ray player, a TV) attached, and the other is a Tenda MW6 mesh network node which wirelessly attaches to two other nodes around the house. This is set in bridge mode, so shouldn't be doing any DHCP stuff, but for some reason rebooting the router never works if the mesh node is still attached - I have to physically unplug it before rebooting the router, then the connection comes back. But there are no configurable options in that device beyond 'bridge mode', which is definitely on. When I first connected the mesh system as per the instructions, it somehow caused the router to change it's default LAN address from 192.168.8.1 to 192.168.11.1 - can't for the life of me work out why.My system information from the router settings is here if that's any use: Has anyone else experienced problems like these with this router, and is there anything that I can do to trace / fix / stop the problems occurring? And isthere any other info I can get from the router settings that might help diagnose what's going on?Sorry... long post...
