@Johnnydec1 Many models of Reolink cams can operate on both bands. I would suggest to turn off smart connect and name SSIDs differently. Then reset the Reolink cam and re-add to the new router SSID.

@Toperr Downgrading FW procedure is the same as updating but with an older FW version - in this case v1.0.7.

@PEEPO This could be due to a 5GHz wireless channels that are not supported on the TP-Link USB wireless adapter. You can change the hotspot wireless band by: Switch to 2.4 GHz on iPhone Step 1: Open...

@echeng That would be a good troubleshooting approach. If the MoCa adapters are not the culprit, you can reboot the AP2 and if the issue persists to swap AP1 and AP4 to eliminate models mixing.

@mtinker33 Refer this thread for your issue.

@maheshgv Since you can't downgrade from V1.1.1 you may try this test FW and check if the issue has been resolved.
