There are two statitions with Atherous 5213 cards and MT 2.9.2.They work linked from 3 months.The first one have never been crashed,but the second may work maximum 1 week.I have changed everything which can be change but the computer still crash.Anybody whith the same problem or may khow how to fix it ?
Yes they are… upgrade to 2.9.12 it´s the latest and more stable version of RouterOS
Regards
Today,when the computer crashed again I went to the other computer and when loggen into MT I saw that the two routers were linked,but when i tried to ping the another antena’s IP received only request timed out.So it’s look like that the computer not crash,but there is some problem which i can’t resolve.
Hey cibernet, how many wireless users you have tested with the new 2.9.12?
Have you upgraded to 2.9.12??
About 50 per wireless card.

Hi! Thanks for the reply, now a think question, if i have a RB532 with 1 minipci wlan, i have support to 50 concurrent users??? if have 2 minipci wifi, support to 100??? or the limit is by the hardware of the rb532?
Thanks and regards!
Alessio
You can handle about 200 wireless users per BR532… it deppends on the type of users, service, etc…

200 with how many cards?
Thanks in advanced for all your answers…

Here’s a few benchmarks I have done using Routerboard 530’s and SR2 Atheros cards…
in optimal conditions one user can achieve 6-6.2mbps connected @ 11mbps with 802.11b, and about 4mbps @ 5.5mbps (UDP).
802.11b/g or 802.11g can achieve a maximum UDP throughput of 20-22mbps
Of course in mixed mode 802.11b/g there are sags in the data throughput as aposed to pure g mode.
Didn’t do any 802.11a tests, but I’d bet it doesn’t do much more than 22mbps, i think thats about the max for the routerboard 530 without NSTREME.
So you figure you have 4-6mbps to share on one AP between 50 users w/ 802.11b. It all depends on how you structure your SLA’s… This is a packet switched network so there’s no linear equation you can set to the amount of users. It’s all based on usage, and what applications your users are running on the network. QoS and bandwidth management come into play here..
Yesterday I have installed 2.9.6 and at this moment there is “uptime: 1d5h24m15s” 
.Now routers are connect @ 54mbits tx and rx with ~ 35% ccq.Before it was 54Mbits/36Mbits @ 25% ccq.
2.9.6 ??? upgrade to the latest… 2.9.12…
Regards
2.9.12 is much better than 2.9.6 higher transfer rates and support of 8169. Many bugs are resolved and there is major driver support for atheros cards.
