Hi all. Similar to some other posts, I have been experiencing internet connectivity dropping frequently, both wired and wifi. I didn't notice this prior to the pandemic, but I'm thinking the issue wasn't as noticeable since we were only using internet recreationally. Now with work and school from home, frequent loss of internet may as well not work at all.
I've tried 2 different Netgear C6250 as well as my previous Motorolla SB6141 and experience the same issue. I upped my speed from 75 to 200 mbps. I had a tech out who switched out my splitter and tightened connections.
It seems the down power level may be too high (up to 12 or 13) around the times of connectivity loss. Up power level (up to 47) seems fine, SNR (about 39) seems fine according to what I've read.
Can't post pic of modem status, but I'll see if I can paste it in next post somehow.
Still no response from xfinity. I've since installed a 6 db attenuator before my switch. Lowered ds power to 0 to 2 which is in good range if I understand correctly. Raised upstream to 40 to 42, which is in good range as well, I think...?
Anecdotally, I think this reduced issues, but has not resolved entirely. Logs indicate I'm still having T3 and T4 issues. Also noticed during an internet drop today, upstream channel 1 was not locked and power at 0. Any ideas what's going on?
Still no response from xfinity, still experiencing T3 and T4 issues. Based on what I'm witnessing, it looks like I may get a surge in upstream power around the time of internet connectivity drops. I'll try to capture the power levels at the time of a drop.
Getting pretty frustrated here that phone support can't help and no one seems to be responding on this forum. Going to start shopping what other service providers I can try out because this issue is without a doubt coming from xfinity.
