Conflict with version

Hi i has a big trouble, a company what i work has many router with os 2.9.7 and we buy with os 2.9.12 and this version dont connect with our rbs, anybody can help me and tell me why dont connect this two version

maybe you setup Nstreme on one with MTs, but on the other don’t, so you can’t connect

murdock,
there should not be any problems to connect different versions of MikroTik RouterOS,
but I suggest you to upgrade to the latest 2.9.18 version,
than follow this example to connect two wireless routers,
