@TP-Link Too late, I've sent it back to Amazon and got a full refund.

I won't be buying your products again.

@Dogzdinner  I'm past my Amazon return window and am waiting for an update from support.

I now have my VR2100 working as a router only, as that's more (although not totally) reliable.

Product specs are great, but reality is the opposite, unfortunately.

Not only poor quality but their promises sum to Zero.

They even offered to send me a WiFi repeater or EoP device as compensation for the time (many, many hours) I've spent helping them to debug their appalling quality firmware. That hasn't materialised either.

I certainly wouldn't recommended TP-Link either. For home use and especially in commercial application.

@Dogzdinner  P.s. my one star Amazon review reflects my findings and observations, and hope yours does the same.

@AllanB I bought mine last November! Got on to chat with Amazon, pointed them in the direction of these forums and got a refund on my card immediately!

As long as it is under 12 months old they are obliged to either repair or refund. Once they realised it is a known problem, they chose to refund!

For information, just received another Beta and it has the same problem as before. Somewhat random reboot after a few hours with no dsl connection afterwards.

I'm having the same problem as most folk in this thread - Firmware Version:1.5.0 0.9.1 v009e.0 Build 210722 Rel.37847n Hardware Version:Archer VR2100 v1 00000000, and reboots every 1-3 days. On my old router I had line rates of ~38Mbps, its down to 19-21 due to the frequent reboots. I'm in the UK on talktalk, the reboots have happened pretty much since I purchased the router in early 2020 but I couldn't return it as it's critical for homeworking. TPLink, please help!

@Kevin_Z 

I have been having the same issues as many of the posters, I've decided to upgrade to the the Beta firmware: 1.5.0 0.9.1 v009e.0 Build 210722 Rel.37847n

I still experience the DSL drop-outs which means no internet connectivity for at least 5/10 minutes whilst the VR2100 initiates again.
Quite often this occurs when a YouTube video is being watched or a Teams audio/video call is taking place.

I will follow this up with an email to create a ticket however just so other readers/posters can see if their issue matches mine I've provided answers to the required questions below:
 

1. Reboot frequency and timing before and after installing the above firmware: Before the firmware upgrade it was very sporadic, hard to specifically pinpoint but normally at least once a day when working from home (Mon-Fri) and would occur during Teams meetings/YouTube videos. Now that the firmware has been upgraded I'd say this has reduced to once every 2 days.

2. When did you purchase the modem, when did the auto-reboot issue start to happen? - Router purchased 30th June 2020 via Amazon

3. Where are you based, and who is your ISP? - England - TalkTalk now but previously used Sky and same issue.

4. Did VR2100 work on the wireless router mode or DSL modem router mode? connection type is on PPPoE or Dynamic IP? 
---if it is on DSL modem router mode, is it ADSL or VDSL? - Router is in DSL Modem Router Mode set to use Auto Sync-Up modulation type and the specific type is VDSL2.

@Kevin_Z  I had upgraded to the latest beta firmware on vr600 and auto reboot got fixed but there is another problem with parental control when put on whitelist
