I've been having T3 & T4 Timeouts for as long as I can remember. I've had a few techs out to attempt to fix it. Every time it was seemingly fixed, but then after some time the issue would return. The longest I had gone without any issue was about six months which was after the first tech visit, and the shortest was about a month which was after the second and third tech visit.
Everything is fine as far as I can see, so I'm at a complete loss for what could be the cause. Levels look great, I don't have any loose or excess splitters, and the wiring outside was just recently redone from my last tech visit. Hopefully someone else has some insight because this is really driving me insane.
I should also add that I've tried replacing my modem in the hopes that it was damaged. I originally had an SB6183, then I switched to an SB6141 and the issue ceased for about a month. Evidently it came back so I thought maybe I just had bad luck, so I replaced it with a brand new SB6183. Unless I have horrible luck and my equipment has been unrealistically faulty, it's gotta be something else.
Here's a link to my modem's status page and the event log. I have an Arris SB6183.
Solved! Go to Solution.
Throwing modems at a signal quality or level issue is a waste of time and money, bet all modems are good.
Please copy and paste the signal page here, I can't read or tear it apart here... to do comparisons.
Do you still have the other 2 modems?
Yes, I still have both of the other modems. I wasn't thinking the levels were the issue at the time, but that the equipment may have just been faulty and causing a reboot or something. Please forgive my ignorance; I'm not particularly familiar with a lot of networking.

Your line levels are in the center of the acceptance window. They are NOT the cause of your problems, and all three modems are probably still good. Your problem is almost guaranteed to be a loose, corroded, or broken connection in TWC's outdoor cabling.
A T3 timeout is the status message when the modem briefly fails to receive signal from the node. Your TV video freezes, your download stops, Windows says you have no internet connection, and your VPN drops. If the signal returns within 3 seconds, everything resumes except the VPN. However, if the head-end signal is lost for more than three seconds, the modem decides that something major is wrong and changes the status to T4. This is an extended loss of signal, often due to a broken overhead cable connection. These status messages are NOT viewable by the tier 1 folks who answer your help calls or chats.
NOTE: We have heard reports that Spectrum may have loaded modified firmware into some modems that changes those timers by a factor of 10. The result is far fewer error messages appearing in the status logs.
All right, thanks for the help MsRaye & karlbeckman. I'll get another tech out ASAP and report back. My only concern is whether they will actually find the source of the problem or not. Seems like every tech that comes out knows well enough what they're doing, just that they miss the actual cause. Anything specific I should tell them?
Channel 1 is the "home" or start channel and having correcteds/ uncorrecteds on it is a larger problem than on the rest . 657 mHz is local broadcast ch 45... is there one on the air in your area? Enter the zip code, state and 100' antenna ht at www.tvfool.com

I'm not sure how to go about interpreting this, so I'll leave the link with my results.
Although 45 is weak, 47,49 and 50 may also be an issue.
I kinda don't believe tv fools level on 45, It seems a lot stronger than what's listed where I am in the 44087 area
45= 657 mHz
47= 669 mHz
49= 681 mHz
50= 687 mHz
You're on the Akron system best I can tell.
Repost the level page again, let's see what the counts are.
if ch 1 is still 657 mHz and counts are really high, I'd try a factory reset on the modem, to see if the headend will assign you a different first channel and if that helps the timeouts and speed issue
