This topic may help people complaining about the nv2 multihop tcp issue. When we reached 250 cpe’s on our flat bridged network, we noticed significant performance degradation. Although broadcast packets were not overly high we realized that it was continuously using air time. A friend of mine recommended going fully routed so that is what we did. We also went a step further and put all cpe’s in station only mode and turned off ‘enable bridge mode’ on the AP wireless settings. Running a btest from a windows pc with 10/100 lan card to a lite 5, two hops away connected to a SAr2(10 subs) yields 70-95mbps. The cpe’s and AP are running ospf, no nat, no firewall rules, no bridges, RouterOS 6.29, only-hardware-queue on all interfaces, fast path enabled. All btests were performed using 1 tcp stream. I hope this helps, good luck.
Can you describe it ? I have point to point AP bridge other side station bridge you change the mode to WDS ? and only routing on interface ? I have several link in NV2 multihop and problem tcp single thanks
Sorry for replying so late, I did not use WDS anywhere in this setup. Just put the AP wireless setting “bridge mode disabled” and on the client side, “Station” not station-bridge. You should only do this if you are running a fully routed setup otherwise you will loose MAC transparency. Mikrotik states that “Station” mode is more efficient than “Station-Bridge”. Remember, on a standard bridged network, all packets transmitted by one client go to all clients connected to that bridge although the packet is only accepted by the client it is destined for. At least this is what I am told. With that theory in mind, a lot of air time is wasted on the AP.
Hi orangetek, thank you for posting your experience!
May I ask you to post your configuration?
I mean: exactly, apart from wireless settings (bridge disabled), how did you achieve a full routed configuration on AP?
