sir the latest firmware of slate GL-AR750S is very very buggy… after loading zip file of open vpn files,the whole router freezes… response…even loading the ovpn files takes more than an hour…please check that and create a very very smooth transition on vpn section…it freezes a lot

Please try the latest testing firmware build - nobody else has reported this problem.

What ovpn did you upload?
If you upload the 20MB Nordvpn config then you will have a problem because it is so big.
