FEC errors and such.

I was looking over the Status tab in the UI of my modem the other day, while I was admiring the technological miracle that lets AT&T deliver internet that is 33% slower now than it was in 2005, and I noticed the FEC errors seem a tad bit high. Does this seem out of spec to anyone else?

FECs are corrected errors and it's not unusual to see some quantity of them. Your numbers are high; try factory resetting the gateway and see how fast they accumulate over time. Storms can create a high number of FEC in a short period of time. Generally acceptable FECs per hour / day is large, 100 per minute, 6000 per hour, 144000 per day. Noise on the electrical lines from motors, monitors, TVs and other electrical devices can create errors. The question is are the errors from outside the residence or inside the residence- or both. If the numbers accumulate to a high level more rapidly than mentioned above, contact support. They can run a line check and equipment diagnostics remotely.

Your downstream noise margin is less than 6 required for ADSL2+... the higher over 6 the more stable the service. 

 

At 2.6 I am surprised you have any service at all.

 

A tech visit is recommended to determine if margins are good at terminal, NID, jack.... with equipment disconnected.

 

FV or foreign voltage may be an issue, do you have any wiring connected to the ethernet ports on the gateway? Tech can test for FV as well... flat screen tvs and monitors are known for these as the cabinets are plastic instead of metal (no 3 prong outlet with ground plug) thus the high voltage from these screens can follow path of anything connected to them.

I know the numbers were good at the pole a month or so ago. They changed the pair that I was on. The only thing plugged into the ethernet ports is a firewall. I've tried 3 different modems with similar results. I'm going to replace my cable that supplies this jack it's 15 years old now. Then if that doesn't help may have to make an appointment. It started acting stupid, ie. dropping sync, 2000ms ping times back in 2009. It hasn't been right since. My service is hooked up at the CO. They won't back feed me 300 yards from the 60Mbps service up the street. lol
