RBSXT-5nDr2 dead after fw update

Hello,

I installed the latest firmware (6.38.1). After that the wireless link was disconnected.
I made a reset and after that I have no more access. I tried the static IP and the default IP 192.168.88.1.

What can I try to get it working?

I had a similar problem only yesterday with a RBSXT-5HacD2n when I did a RouterOS upgrade. What finally worked was using “netinstall”.
Remember that for netinstall, you need to disable Windows Firewall and run netinstall as Administrator or it’s likely your device won’t show up in the list.
Best to Google for detailed instructions but here are some to get you going:
