Note the router is a VR2100, not 2800 as the 2100 is not listed in the Model box!

Firmware Version:1.1.0 0.9.1 v009e.0 Build 200116 Rel.60756n 
Hardware Version:Archer VR2100 v1 00000000

I have been using the VR2100 since 29th September  (2 weeks) and it restarts every day.

I didn't notice at first, but I have 1 device that doesn't reconnect to the network when the network goes down.

It seems to be early-ish, before 9am but I have had it restart once in the afternoon.

My iPhone will swap to 4G for approx 1 minute.

Reboot schedule is disabled.

I am in the UK.

I am on Plus.net Fibre extra.

I have reset the router (by holding the reset button at the back for 10+ seconds) and re-entered all the settings.

Interestingly, I reset it at just after 7am on Sunday morning and just after 7am on Monday morning it restarted.

I had been using an HG635 modem wireless router from Talk Talk which stays connected until I restart it.

There are no logs before the issue because it seems to clear them when restarting.

The time is logged incorrectly, but after connecting this is corrected.

Is there any thing I can do?

I have 2 more weeks, then I will need to return it to Amazon.

Thank you
