I have the same issue with a VR900 that I've had for a couple of years. Tried a firmware upgrade from Archer VR900(EU)_V3_170303 to ArcherVR900(EU)_V3_200708 to resolve a couple of issues and then it will not connect to Plusnet. I've tried a factory reset etc on the new firmware but cannot get it to connect so I had to downgrade to an older version again.

@Sunshine, thanks for offer to look at this, but the reason I bought this router was because I'm upgrading to VDSL2, which has now been implemented so I can't check the original connection. In the next day or two I may try the firmware upgrade again to see if there are also problems with VDSL.

@Sunshine also see this post. Looks like the last-but-one firmware is OK, it's the most recent one that causes the problem

I can confirm the same problem connecting to plus.net.

Firmware version "Archer VR2800(EU)_V1_170809" works.

But version "ArcherVR2800(EU)_V1_200710" does not work.  It negotiates a VDSL2 link, but the PPP session always fails to login.

I manually configure exactly the same VDSL and PPP settings with both firmware versions.

I also believe the latest firmware for model VR600-v2 (ArcherVR600(EU)_V2_200701) is broken with the same problem.

Thanks,
Chris.

Same problem but with Zen ISP. I never tried downgrading as the time was getting on but it's nice to know I can as it's an expensive doorstop otherwise. I ended up using an older modem/router I have until they sort this out ( I HOPE ).

Add me to the list of people unable to connect to PlusNet after upgrading the firmware of my Archer VR2800 to ArcherVR2800(EU)_V1_200710. Downgrading to the previous version of the firmware resolved the connection issue.

 I queried the problem over 3-4 weeks and still nothing from TP-link, They have forgotten the VR2800 etc for the newer AX range. I shall think about which manufacturer gives true support for my next modem and does not submit a beta firmware to the public.
