You can make a PtP connection with the L3 license on both devices.Yes, it is kind of too good to be true.
I should probably add that the LHG ships with RouterOS License level 3, to the AP has to be upgraded to level 4. Not a big deal though.
I'm having the same problem!My 493G not booting any more after upgrading firmware included in ROS 6.5 (from v3.08 to v 3.10). LEDs lid but no beeps or anything!
Any ideas? Please help ASAP!
