OK, It seems I was a little optimistic, It did last 5 days, but rebooted yesterday and again overnight, so although not fixed it seems that they are heading in the right direction... Hopefully..

I have been watching this thread with interest over the last few months. I bought my VR2100 in July to replace the ISP provided one, TalkTalk in the UK, and it would reboot every couple of weeks, occasionally more frequently. So it would seem I was doing better than most on this thread but it obviously still had an issue. I updated to the latest firmware when it came out in December, which seemed to have little effect on the rebooting issue. Then I installed the first beta firmware in January and my router has not rebooted once since then. It has been switched off twice since January due to power cuts, but it has not rebooted itself. After a restart it will re-sync the line every couple of weeks, but this takes all of 20 seconds and is usually in the middle of the night. As of a few weeks ago it seems to have settled down, so far 26 days without dropping the line.

It would seem that this router is capable of working correctly, hopefully your issues can be resolved soon as it does seem to be a good router, when it works.

@DGS You have a very low CRC error counts which is probably helping with your VR2100 router stability.  I was getting about 1 CRC error every 7 minutes where you are getting only 1 error every 81 minutes.  My VR2100 rebooted about once every couple of days which reflects what others have been finding on this forum.  I gave up with the VR2100 and got my money back and I have replaced it with a Fritzbox 7530.  Not one reboot or Wi-Fi drop since I got it nearly 2 months ago.

26 days uptime? WOW! Maybe any problem with AC adapter for EU? In UK you have different electricity socket.

Now crashed and only about 1 day uptime. It is very very weird.

@Zajic I am also from the UK and I had experienced the same issues that you have.  Hence I do not believe the EU power adapter that you have will be at fault.

I am in Northern Ireland and have the reboot problem

@scoomby 

On average the CRC errors are about 1 every 81 minutes, but in reality, from my observations, it can go for days with no or just a few errors, then you get a sudden burst of errors. External interference? I have seen the line re-sync before with less errors than I currently have. So I am not sure that it is always due to CRC errors. At least in my case.

@Zajic

I would be surprised if it was down to the adaptor as they are probably exactly the same electrically with a different style plug attached. Unless the QC on them is really poor?

@DGS 

It was only idea. 

And about DSL:

My VR2100 working as 'Wireless Router Mode' only with VLAN+PPPoE and still crashing. 

My network:

DSL line RJ11 -> RJ11 other device for only DSL modem (1x 17a profile)/no wifi/no dhcp/LAN-TO-WAN RJ45 -> RJ45 VR2100 as 'Wireless Router Mode' VLAN+PPPoE.

Something must be terrible wrong with VR2100. I have it as classic router with VLAN+PPPoE. :x

I again disabled 5G WIFI. But I'm afraid the result will be the same.

@Zajic 

I run my wi-fi using One Mesh with two RE300's, I don't know if that has any affect on the reliability of the router? If it was a software issue then, maybe?

@DGS 

I have 2 RE220 on OneMesh. I have about 40 connected devices - roughly half wired and half on Wi-fi.
