Broadband speed degrading over time and Errors(pkts)

[#1]

Good day.

I have question about broadband speed. 

Every 1,5 Year or two i have to call someone to reconnect connection in cabinet as line speed slowly degrading . Once they reconnect it it stays stable in between 76-78Mb/s ( In router ) but after few months again start to fall down currently 66Mb/s ( in router ) ( 55Mb/s speedtest.net )

Why is like that?

Second thing how much Errors(pkts) are normal ?

Current situation:

Line Status: Connected

DSL Modulation Type: VDSL2

Annex Type: Annex A/L/M

  Upstream                               Downstream

Current Rate(kbps)	20000	65492
Max Rate(kbps)	21886	79361
SNR Margin(dB)	6.4	6.2
Line Attenuation(dB)	16.2	10.9
Errors(pkts)	221	21594

Thank you
