EnGenius EPI-3601S detection problem?

Im using the old compaq deskpro pc’s running Mikrotik OS 3.13 on them as a cpe, and they dont seem to pick up the EnGenius EPI-3601S wireless card. I dont have a problem with d-link or netgear cards but i need the extra power for the longer links

did you try v3.23?

Those cards are probably too new for those Old compaqs.
They dont work with anything PCI v2 from what we found are seemed very picky.

Cheers
