I have 20 of the European TL-WR841N v14 routers installed at a facility. I've received reports of connection drop-off issues, mainly related to Apple Devices. I'm aware that there are adjustments that can be made (which i have done) to mitigate this issue.

I'm looking to update the firmware - they're currently on 0.9.1 4.17 v0001.0 Build 200903 Rel.58674n.

I've just seen that the US equivalent model has a new firmware updated, released 2021-04-09 (TL-WR841N(US)_V14_210203).

However, the EU model has not been updated yet - the latest being November last year. I understand that there are subtle differences between the two variations. Looking at the change log for the US model, it seems to have addressed some of the bugs we're experiencing.

Generally speaking, how long does it take for regional specific firmware versions to be updated? Our EU models rejects the US firmware, so it's likely I'll have to wait until the EU version has been released.
