Changed to a different filter ( as suggested by BT) and all seemed well. CRC and error seconds stayed very low for 20 minutes.
Plugged in original filter again and still low CRC and error seconds!
Now whichever filter I use it's gone back to high CRC and error seconds.
It's occasionally showing Modulation: Unknown or no mode configured then goes back to 992.5
Utterly confused. Will leave everything alone now and see if I get the massive speed drop later.
I miss cable 😞
errors are still high for only 1hr+ connected suggesting there is still noise on the line. see if it will hold connection and maintain speed
13 hours. Looks like there was a disconenct at some point as I hadn't touched it for about 16 hours.
CRC and Error seconds still massive.
Also ran an automated speed test that runs every 20 minutes. Speeds all over the place from 12mb down to 1.5.
if you are still in test socket and quiet line test is ok then with that very number of errors and connection drops I would contact the mods for help
can take up to 3 working days for mods to contact you
