NV2 vs Nstream vs 802.11

Thu May 15, 2014 11:37 pm

I have talked to my vendor and read these forms and for the most part I here NV2 is a good protocol that works well for people. But I have had nothing but issues with it and I'd really like to understand why.

Now If I run a link in 802.11 I'll get pings across the link 2-5ms but once the data rate picks up people get starved for bandwidth and the ping will flux quite a bit. So I run Nstream which handles the bandwith sharing better and my pings are 15-20ms and data rates 3-5megs downrate for most of my towers.

Now when I switch to NV2 the pings will go to 150-200ms. While people do seem to stay connected better and not dis-associate as much but people can really tell the differnece when things are 150-200ms. And most of my customers are gamers.

The majority of my AP's are rb433ah running r52hn cards 10mhz channel into a 12dbi omni running 802.11G only. I am running os 6.1 on the ap's and 5.6 on the clients.

Have any suggestions or thoughts? I am running 13 towers, and I have yet to have any of them run reliable on nv2.

Regards,
Michael

You use very old version of RouterOS on both side...

Upgrade to 6.7 (ultra-stable for APs) and 5.26 (stable for clients)

In old version you use, NV2 is not fully implemented as are now and Nstreme are better on latest version...

Nv2 works great for me in point to point links, but I haven't had as good luck in point to multipoint.

Nv2 @ 900MHz stabilizes the latency, but drops my bandwidth @ 10MHz from 5-7Mbps to 2-3Mbps regardless of nv2 timing. Too much noise here for TDMA apparently.

Nstreme works fine. 802.11 works decently until one customer gets online, however, the max bandwidth is lower. 802.11 bandwidth is still higher than nv2 on this particular AP.

For my backhaul link, 802.11a @ 40MHz, nv2 bandwidth is amazing. It took another link, 24 miles, that had the occasional problem and made it near 100% stable.

on x86 i suggest to use 5.26 -> we had lan gigabit port flapping and freezing with newer firmware
for 912hpnd optimal is 6.13 latest ros, max throughput

You suggest this on YOUR machine, because you probably have not fully supported chipset on the board.

I suggest 6.7 on x86 machine.
In my three x86 device I not have any prolem about port flaping or freezing, and on all disable-running-check are set to no.

And... 6.13 works great on my x86 :)

MT support confirmed there are some issues with v5 x86, something related to simple queues and the kernel itself. I haven't tried v6 yet myself. I'm a little hesitant to upgrade the edge router. Funny thing that...
