@SharkAttackRJ To build a Onemesh, RE605x should be in router mode (default settings). Follow this guide for configuring the RE605x in Onemesh with AX90.

@dis69 Nothing abnormal in the connections. Probably @Sunshine will come up with a way to troubleshoot your issue. I just noticed that there's a new FW release for US region marked as version 1.1.1...

@Hokr_1970 What make and model is your main router ? When you did the RE200 settings 1m from the router was that successful ? Did you try the WPS method for pairing these - here.

@yanck That's the most probable outcome considering current thread issue.

@BenTee Try setting the 5GHz band channel width to 80MHz and test the speed again to see if there's any difference. You can also experiment with setting a different wireless channel for 5GHz band.

@Ian1917 AX53 is a wireless router - it's not a modem router and doesn't have RJ11 port. You'll have to use your ISP modem and connect AX53 behind it.
