Round 3 - Latency, Jitter, and Speed Issue

The most common cause of issues that I've seen is noise on the cable network. This can be caused by anything and can appear at any time. I've had this problem on my connection too. One time it was caused by a neighbor hooking up an old cable that let noise into the network. Another time it was caused by a tech who forgot to reconnect a line after working on someone else's service. Another time it was caused by a faulty amplifier on a pole. This type of problem can be caused by almost anything and can appear at almost any time.

The best way to check for this is to make sure all of your indoor connections are tight, replace all indoor cable with high quality brand new RG6 cable, and remove any unnecessary splitters and amplifiers. Then let your modem run for 24 hours and check for uncorrectable codewords and/or T3/T4 timeout errors. You can post your signals and logs here and someone will usually help you understand them.

If you've ruled out any problems with the interior connections all you can do is call for a tech and don't be scared away by the threat of being charged $75. If you properly ruled out your indoor connections you don't need to worry about that.

It can be frustrating. I've had about 6 tech visits in the last year for this problem. Every time it was caused by something different and every time it was caused by problems off of my property and out of my control. The good news is that they did eventually fix the problem, but I know it can come back at any time. That's just how it is with cable internet.
