With my continuing saga, some of it may be done to the current Draytek modem/router in use.
Without going into a long winded reason, it appears the Draytek is causing a lot of resyncs by itself, and also logging a lot of errors that just are not seen on the line (according to the engineers test equipment), which it is seeing as a problem and dropping my speeds. It's almost like its performing DLM by itself, which may be a good thing as i guess this would prevent the real DLM intervening if there were problems.
He plugged his meter into the phone socket, whilst i had my laptop plugged into the Draytek.
His tester read 0 ES, and yet the Draytek was pulling in 10+ immediately after connecting.
So, i thought i would maybe try an alternative to see if it is the Draytek.
I have an HG612, and after plugging that in, i get a much lower sync, and with the phone plugged in, i get no CRC errors, but an awful lot of FECS and HEC errors. (Draytek showed a fair amount of FECS but 0 HEC??).
I am considering asking my ISP if they can speak to Openreach about changing me from the ECI cabi am currently on, to a Huawei that is a couple of meters next door to it.
Anyhoo, can anyone recommend a modem or modem/router that can be bridged and that will not be so keen to keep logging errors?
