TP-Link Archer C7 AC1750
Hardware: Archer C7 v.5.0
I updated the firmware on (14/12/2021)
Old: version: 1.1.2 Build 20210125 rel.37999(4555)
New: version: 1.1.3 Build 20210519 rel.50598(4555)
Since the update the router has been dropping the internet, all devices remain connected to wireless / LAN and can see each other.
General internal communication works fine, i.e. file sharing between machines.
However none of the devices can access the internet. At first I thought it was the ISP router and rebooting the ISP router did not resolve
the issue. Once I rebooted Archer C7, Internet was back to normal so I thought.
Internet connection remained unstable, connection was dropped again after 24hrs.
However this time I knew it was the TP Link router, restarted router and connection was back again.
Due to the issue, I downgraded the firmware back to the old version 1.1.2 Build 20210125 rel.37999(4555) and since then Internet
connection has been stable, no more drop outs.
Conclusion, there is an issue with the new firmware released on 2021-08-13 (Archer C7(EU)_V5_210519 / 1.1.3 Build 20210519)
I have reported the issue to support, and have been advised they are looking at the problem.
In the meantime I would advise all, do not update your Archer C7 v5 to the new firmware published on 13/08/2021.
