Hi,

I've had BT Openreach crawling over my house over the last week looking for reasons on poor fibre ADSL performance.

The guy today managed to isolate a huge increase of FEC errors (over 70,000 a min) on my phone line, down to my TP link switch which really surprised me.

I have a switch room in the house, where two incoming phone lines sit, alongside a tp link 24 port switch, and a number of other pieces of kit (PC, monitor, speakers, NAS, routers etc).

First, we turned the power off in the whole house, and the FEC rate dropped to a couple of hundred. One by one, we turned on various power sources until the only one that made a huge impact was the TP Link switch. If this was powered off, we got only a few hundred, as soon as it was powered up, we got 40k plus from a range of 2-3 meters.

Is this expected from a 'business' level device?
Is it faulty?
Should I return it?

Thanks,
Dave.
