[Beryl Plus] Firmware 4.2.0 no Repeater speed

i have a odd issue, my A1300, after updating to 4.2.0, isn’t connecting really good to the WiFi Repeater. Speeds are really slow, like 2 Mbps. The Luci Interface says it has a connection of 650Mbits, but it can’t reach above 10. The Repeater itself is a phone with 5G, i downgraded the Firmware back to 4.1.2 and all works again. Also factory resetting and reflashing 4.2.0 didnt solve issue. So 4.2.0 is unusable for me right now.

Will you have the same problem if you go back to the old firmware version?

Going back to 4.1.2 did solve s issue
