Using beta version is not recommend in our company policy
In that case, you have to forgot using mikrotik i think. In many cases, the new version is wrong than the previous ones.
The changes are not well documented, so maybe you can think, the changes in the changelog does not counts in your side - but some changes not documented in log - so you don't know if the problem is in your side or mikrotik ROS, or hardware.
If you want to be sure,
do NOT use the newest version, just those what
qualifed and worked for weeks for other forum members. Yes, I also sold a new intel mobo based router - what worked only with 6.0b2. The customer is understand:
- he have to take the risk
- or buy an expensive PCIe multiport NIC
- or buy an old and much slower (and EOL'd) motherboard.
