So I ran into a problem after installing a new Mikrotik back-haul. Reference the diagram below:
I have a building that I’m serving wireless to, and I was doing the back-haul with some old Redlines…this all worked fine. Well, the Redlines eventually tanked on me, so I swapped them for some 411s. When I got the 411s in, I threw 3.30 on them and installed them. I could pass traffic fine across them, no problems. I then hooked up the building AP and left. I then got a call saying that the wireless was useless…nice.
I went out to investigate and I was getting some interesting results. I connected to the AP just fine. I opened winbox and could ping from the AP to the internet just fine. With the ping still running, I tried to browse to any site other than google, and the pings stopped passing… I rebooted the AP and got the same results…everything was fine until I tried to pull a real page, at which point the ethernet between my AP and the back-haul radio stopped passing traffic.
After futzing with it for several minutes, I noticed that my AP was still on 3.10, so I upgraded the OS to 3.30 which is the same version my back-hauls are running. I started my ping again, and browsed to a site and…it worked perfectly. Nothing dropped and all my pages loaded. There appears to be a bug that when 3.10 tries to communicate with a 3.30ish MTK, the traffic just stops passing.
I hope you guys don’t run into these issues, but if you do, upgrade!
