Cant find 2nd radio 5ghz on old firmwares

Hi!

I have tried almost all of the older firmwares for the R8000 and on all of those I cant see the second 5ghz radio WL2. 

When I try the latest firmware from late december I can find all 3 radios, but on this latest firmware OpenVPN Client wont work at all.
Anyone have a solution to this problem? Seems im the only one with missing radio, googled all over the internet and cant find a solution or a similar problem.

I have tried to reset the nvram before and after firmware updates. And when I try the older firmwares the radio shows up on wifi list when I search on my laptop but its on default settings with no password. But It dont show up on config screen in DD-wrt.
Or is there a solution to get OpenVPN to work with the latest firmware?
