@David6479 I was afraid too that that never happened before to me. I spent all night fighting and wasting my sleep to revert that. So I try sum all up now the 1.0.10 firmware for BE550v1 EU: - Before...

@Kevin_Z Hello, I do 3rd approach to upgrade my 2xBE550v1 and finally worked on my main BE550v1 ( i had to reset all to factory settings before upgrade other way device was unstable and no internet)...

@David6479 I had before 2xAX55 and 5GHz/2,4Ghz signal its stronger than on 2x BE550 on same place. But when i back to home i will try install again that beta firmware and test it.

@David6479 Ok i will try 3rd try for this firmware but seems i need first disconnect all cabales and devices from router first, before flash it. Other wise get bugged lol.

@David6479 Do you have US or EU version of BE550v1??

@Kevin_Z Thx for answer but the new beta, dont work stable on our devices ^^" on mine 2x BE550v1 EU don't work at all. So i cant even do test or compare to previous one. Only what i can say its not...
