Re: Intermittent drop outs - multiple T3 and T2 timeouts
Hi Meg, Thanks for your help. Yes, normally run in modem mode, but let me know what day you would like me to switch back and will make the change so you can take another look. Latest… No reboots over last couple of nights but upstream QAM does not look stable and still seeing some packet loss. Have actually noticed small and intermittent changes in down and upstream channel power levels (noise the modem is struggling with?) too. In case helpful, not long ago Beth helped to get to the bottom of an SNR issue in the vicinity which was causing low level packet loss for months. Not sure if could be something similar. Thanks again Andrew410Views0likes1CommentRe: Intermittent drop outs - multiple T3 and T2 timeouts

Hi John, Not sure if managed to get to the router. Still seeing the low level packet loss (got this previously when there was underlying SNR problem) and still getting some T3 errors, even in the short time been in router mode. Also see upstream channel changes, pretty much almost always the OFDMA channel. Reverting back to modem mode, wifi coverage is an issue when using the Hub 5. Let us know if need me to revert again. Thanks again for your help. Time Priority Description 13-06-2024 17:08:19 notice US profile assignment change.

Hi John, Thanks very much for checking in. Since issues no longer appearing in VM app, I've observed a couple of further brief outages (nothing like last week) with T3 errors being reported alongside, plus also now re-seeing consistent low level packet loss (no packet loss the few weeks leading up to the problems of last week). I'm pretty sad to say that my mobile hotspot has more reliable packet delivery than my Gig1 FTTC service at the moment. Are you able to check with network team to see if there are any less critical but still outstanding issues which may account for this? I'm pretty certain nothing has changed at my end, but of course as always willing to take any advice Thanks again for your help Andrew461Views0likes6Comments
