Hello, I have damaged Asus router AX88U with 5 and 7 lan not working (caused by storm), rest lan ports are working. I decided to swap BCM53134S. Sadly I had BCM53134M available and after swap lan ports 5-8 are not working. Datasheet says that they are almost same, communication should be same also. Is there problem with my soldering or chip itself or M version is not compatible with router/firmware. Looking forward to hearing from you!
