Yes, well. When it hit 1500+ errors/min I decided to prove that it's either internal or external... hence the lack of data coming out of here. One of the problems is that I have three APC UPS plus about 11 switch mode PSUs in here so establishing a problem with one is a nightmare. Anyway I got down to running just a laptop on battery and the modem running on several different bricks - don't need the router on as can connect the modem via LAN2 directly to the laptop. No difference in CRC levels.
It's all back up currently but running with around a 1000 errors/min. Very, very odd that the SNR is not affected. On ADSL2 this sort of interference would have dropped the conn and come back with about a 12dB margin from 3dB via the DLM. I had 6 months of this year before last but the people who had the faulty monitor PSU are away. Had everything else in the house off as well with no effect.
It almost seems as though these errors are not real! The modem has been powered down and up again four times in the past two hours with no apparent effect. I expect we'll find out tomorow how real it all is...
The Electricity board are working just up from my cab installing mains into a new house and are digging a lot of road up. Wonder whether there's a generator or somesuch or a faulty modem or the firmware is buggy....
Added in Bitswaps/Min graph.
There is a current QLN graph
Edit @ 20:00
Actual speeds are around 55/12 which is pretty well much as it has been, Why are there so few FEC errors?
