Hi,

Im using a Vigor 2860n with my Talktalk DSL line.

I seem to be getting a lot of Near End CRC errors.
I'm new to Draytek routers so i'm not to sure how to troubleshoot this.
Thanks for any help.

Change modem code (WAN >> General Setup>wan 1>DSL Modem Code) & see if is better
or try the adsl/vdsl firmware from UK download page to see which one is better for your line
(if you are updating from older firmware is good idea to use the *rst* file extension & all settings back from the begin manually)
(rst will reset all settings back to factory defaults)
http://www.draytek.co.uk/support/downloads
(each firmware has an alternative modem code)
Is good idea to change first an alternative adsl filter

Thanks for suggestions Babis3g.

I shall see what happens.
