I live in Tarzna, CA. I have spectrum cable internet. 300 mbps down, 25 mbps up. We have 1 line coming in from the street that is then routed to a connection box with 1 connector and ground. That line then goes into the attic with no splitters right into the back of the modem. I have checked all of the connections to ensure that they are tight. Usually I get 350 down with a ping in the 11-17 range, but recently things have been very slow requiring multiple modem restarts throughout the day. And even with a restart, the speeds are very slow (under 10mbps down). The one interesting thing is that the upload speed stays fairly consistant. In the 20-25 mbps range.
I have Motorola MB7621 modem connected to a Netgear Orbi RBR50 router with 1 satellite.
I will post logs in a reply as it's saying my message count is too high.
Here are the most recent logs:
And here is the connection info:
Any advice or help would be greatly appreciated!
Also, your ORBI router if you have it wired for wired backhaul will corrupt the signal and degrade it. You cannot seem to have ORBI router hard wired. The ORBI is downgrading it likely
I also assume that you do not have the modem as a combination modem/router set to continue with wireless also? Have you tried connecting hard wired direct to modem to test speed without wireless?
The MB7621 is not a combo unit so there is no double nat situation here. Also just telling someone to switch providers does not address the problem.
It's possible that the main line from the pedestal/pole/street is compromised somehow...hungry squirrels, pooling water, etc. You show a large amount of corrected/uncorrecteds for being up for only 2.5 hours.
I've thought that as well, but I have inspected the line all the way to the street and don't see any issues like that. The issue is just so strange. With no changes in internet traffic, the speeds are back up to 350 right now. I guess if it was a bad connection somewhere, the wind might blow causing the connection to be bad and then wind blows again and it reseats the connection. The only kicker seems to be that the upload speeds never go down. They stay fairly consistant. I would think if there was a bad connection I would see both upload and download speeds rising or falling in tandem.
When you open a home service ticket, be sure to tell them that your modem is reporting VERY high numbers of both corrected and uncorrectible packet errors on all channels. It almost looks like there is an unterminated length of coax connected to a splitter port, which would allow external noise & signals into your modem. That scenario could also be at a neighbor's home if they share the same mainline splitter out on a pole.
