The device is in router mode and has been since the 20th December. Apologies for any confusion, I thought I had already switched back to modem mode but I must have dreamt it. Below is what we have seen today so far, the vast majority of these are causing disconnects to game services, workplace VPN's or a brief but noticeable slow down of general browsing. You can also see they are increasing in frequency...

I hadn't switched it back to modem mode after going through the last lot of testing. It has now been in router mode since 20th December. As a bit of info from the log, here is a snippet of a very frequent error message in the network log. These occur every 58 minutes past and appear to coincide with the spikes in the packet loss. The error is adjusted a little due to mac addresses being present. 26-01-2026 12:58:36 notice US profile assignment change.

The hub is currently in modem mode but this issue persists in router mode as well so I am fairly convinced that the kit post the point of the modem is fine. As a test, I have connected wirelessly to my works provided 5g modem and I can't replicate the issues on any device when connected to that network. Below is as of today and it has been worse over the weekend just gone. I'll switch into router mode at some point this afternoon as you've requested but, as already mentioned, it does persist through both modes. Does the input that legacy1 has kindly shared identify anything? Re: Regular Packet Loss Causing Disconnects Still no improvement. The frequency of disconnects are increasing again and are most notable during peak hours. You'll have no issues and then you will have 5-10mins of high latency with disconnects. More severe latency/disconnects coincide with the packet lost spikes. I am still in modem mode, the 2 affected devices are both wired, have replaced all ethernet cables and swapped out the coax for another VM spare I had. Re: Regular Packet Loss Causing Disconnects Apologies for the delayed response. The connection is about the same, though straight disconnects appear to be less frequent. Packet loss is still present. I am still in router mode so I am confident that issues stem from the modem backwards rather than with my local setup. It impacts two separate wired desktop PC regardless of modem/router mode and both have had their lan cables replaced since the issue. Coax from the wall box to modem has also been checked with a spare from a previous install, no change there. Re: Regular Packet Loss Causing Disconnects Just to bump this. The connection has improved a little since switched to router mode, but is likely a coincidence rather than indicating an issue with my 3rd party router. There was a bit of what looked like local utilisation issues due to Christmas which has susbsided for now but the packet loss is still present and, whilst not spiking and causing disconnects as often, it is clearly become more frequent rather than consistent intervals. Regular Packet Loss Causing Disconnects Since 1st November I have seen regular spikes of packet loss, initially small and not causing any increased latency or disconnects Progressively this has worsened to the point that the packet loss spikes are virtually on the hour, every hour and are far more noticeable whilst gaming. These spikes coincide with disconnects from World of Warcraft on two different desktop PC's. Above is for 16th December as 17th I turned "allow ping from WAN" off via my Flint 2 router to test as I have heard of regular timed tests (Samknows) causing issues for others. This hasn't fixed my issue. The issue persists via modem mode into a Flint 2 router as well as via the router mode on the modem itself. Impacted desktops are wired but I haven't tested wireless as I am confident this issue will persist. I'll drop the logs in a reply below. Re: Severe Packet Loss (Area04) Thanks for the info, will keep that number handy as the web driven status frequently crashes out for me. Regarding the packet loss, I lost the connection completely for ~45mins then it cam back completely free from packet loss so who knows what was fixed or was the cause for it.... Ignore the 4am loss, that is my scheduled router restart.
