Some weeks ago, I did a firmware upgrade on one of our four Vigor 2860N routers. I downloaded the recommended version 3.7.8.3 (574307 / Vector 2) from the UK website and installed it and all was OK.
The router dashboard now shows version 3.7.8.3 (574307_A/B/C HW: A) Build date/time Jun 12 2015 15:23:18.

This week I downloaded the same F/W version again to update another router. The file downloaded was v2860_3783_vector2.zip and the firmware file within that was v2860_3783_574307.all
After installing it this time, the router showed the wrong modem code version - 3.7.8.3 (571801_A HW: A) Build date/time Jun 12 2015 15:23:18
What is the problem here please? Is it the wrong modem code in this version or is there an error in the labelling either in the F/W file or on the Web link?

Regards

If you check under WAN - General Setup - WAN1, there's options to select the modem code, that should be the ADSL part of that modem code, so when the modem switches back to VDSL2 mode, it should show 574307 again

Hi,

Your reply is much appreciated. Yes, it is as you say. I understand what is happening now.

Many thanks and kind regards
