Any change log about new R11e-LTE6_V026 modem firmware?
I upgraded to this firmware today, and now when I have passthrough enabled and attempt to pass traffic, the passthrough interface drops constantly. Anyone know of a way to downgrade to a previous firmware?
The only way that propably works is using USB to miniPCIe adapter like this:

To do this, you need to contact directly to Mikrotik’s support and request the tools, drivers, firmware and instructions to do the flashing process.

Downgrade can be done but you must ask: support@mikrotik.com or https://mikrotik.com/support for a firmware file
