VR2100 reboots every few hours
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I have a VR2100 that reboots every few hours connected to PlusNet in the UK on unlimited fibre to cabinet. (VDSL2)
DSL using VDSL2, SNR 6.1 up 2.8 down, Atten 1.2db up 10.8 down.
When it is up, connection is reliable.
When it reboots all lights go and start flashing after a few minutes the DSL connection is re-established.
Case temperature is relatively cool, room temp about 18C, case probably 25C.
Nothing in the logs since they are wiped on every reboot. I will setup a syslogd server to capture logs remotely, just in case.
It is a few months old.
Previous DSL modem was the OpenReach VDSL Modem which never disconnected or rebooted except during power cuts (1 per year).
I have read the other threads with the same problem on the same modem and firmware.
Is there new firmware (even beta) available that will stop it rebooting.
Would be happy to share logs, if you would help get a fix sooner.
If there isnt any fix, I can switch to a spare (old DLink), which the VR2100 was bought to replace.

Have received a new debug firmware image (datestamped yesterday 2021-01-06 ) from TP-Link support (thank you), with a fixed DSL Driver. This has now been stable for 24h with no reboots. Also, the error packets seen on the DSL layer have dropped to zero and IP clients are no longer seeing pauses in traffic. The maximum bandwidth seen is marginally greater than the predicted line speed for both up and down.
Uptime so far 22h8m, which is at least 6x longer than with the default firmware on my DSL connection.
So far this new firmware seems to have fixed the problems with the DSL part of this router.
If I don't report back, and you are reading this then assume this is fixed and look for new published firmware.
When configured as a router, I did not have any crashes using the previous debug firmware. None since my last post.
There is firmware (Archer VR2100(EU)_V1_201122 published 2020-12-24) however this crashed for me as a router and as a modem and did not fix the issue reported here.
BTW, TP-Link support is excellent. I wasn't expecting it to be so good for a consumer product.

Thank you so much for reporting back, and it's glad to know the reboot issue is resolved with the debug firmware, please keep monitoring the router performance, we will soon release an official version if the issue is confirmed resolved.
Have a nice day.

I'm also experiencing this exact issue. Also on Plusnet. It has been occurring randomly ever since the router was purchased in June 2020 and nothing I've tried has resolved it. If there is a possibility of making the beta firmware that resolves this available, I'd be very happy to test it out.
Many thanks,
Paul

The router itself has been up now for 12d no crashes on the I had a DSL line drop 5h ago, the first for 12d.
DSL Error packets were 0 last time I looked.
Jan 18 12:12:22 PPP <Info>: Connect time 17491.0 minutes.
I am still seeing some Wifi packet loss and failures for clients discovering or renewing DHCP which could be due to their DHCP client implementation, the wifi signal, interference from other wifi clients. Seems to be fixed by reserving the address and moving the client to static IP.
I think that confirms the fix to the DSL Modem part of the router, hopefully the official firmware will be out soon.

Hello all, sorry to hear that you experience an auto-reboot on the VR2100.
If the auto-reboot issue, unfortunately, persists on the latest firmware, please kindly check if the latest beta firmware we provided in the below thread:

thank you for this.
I've updated our router to the current latest general release and will leave it 48 hours to see how stable that is. ( I'm already seeing the packet errors though. ) I'll then install the beta format and see how that goes. Will update you on here once it's had a few days run time.
Thanks again, fantastic support and service from TP Link.
