What are the client limits for RB333?

RouterOS Wireless Networking
1

I am runnig a RB333 with 1 Sr9 and 1 SR5. The sr5 has about 25 clients. Nstreme is running and I’m using 5Ghz. Performance is in the 8-10Mbps range.

The Sr9 is running 35 clients with the radio set to 5mhz channel spacing no nstrem. I have a clean noise floor and performace is in the 2-3Mbps range.

I am running ROS 3.2 on the AP and my clients are a mix of ROS 2.46 to 3.2. After a day or two of running, I am having a number of clients that are connected to the AP, but are not moving traffic. I can Mac telnet into the cpe’sbut I can’t ping from them. Once I reboot the cpe all is fine. Or if I disable the unit from the AP the re-enable all is fine. If I reboot the RB333 with the wireless interfaces enabled the AP will not recover… I have to telnet in disable the wireless interfaces the enable them one at a time… sometimes, I need to disable all the clents an enable them in groups.

Any ideas, I am starting to lose sleep over this.

Hi,

Here are some suggestions:

First off, upgrade your AP to 3.3, then upgrade all your clients to the same version. We have found best results with clients on 175Mhz procs to run on 2.9.50, with APs (266Mhz or better) on 3.3.

After the update, do a NEW TERMINAL on each client, then do a sys rout upg, a sys check-disk, then reboot. Nand Firmware updates and checking for marking bad blocks can help.

Then check to make sure you don’t have any “shouting” clients (stronger then -45 signal strength on the AP) We have seen crazy results on APs with clients with Tx too strong. Think of it like a conversation, and try to balance your subscribers from -55 to -75 on the AP for best “across the board” performance. This really improved consistancy for us.

Are you running client isolation?

Are the logs giving you anything? how about debug? We have also seen similar problems you are describing with conflicting DHCP servers on the network.

Thanks for the great suggestions I will try.

Should I upgrade the firmware on the AP’s too?

Also, what do yo mean by cliant isolation… taking weaker clients and creating a VAP?

Thanks

If you are not running anything too complex on the APs, I would say upgrade the APs to 3.3. We noticed good results. However, we have seen the bridges on a few 2.9 ->3.x upgrades go a little wierd, and had to be recreated. We also think 3.x on 175Mhz procs (112/133C) doesn’t seem to hold well. But on the 532s and 333 seem to work great! Just our experience…

Anyways, backup your configs and give it a try.

Regarding Client isolation, I mean do you have DEFAULT FORWARD turned off on the wireless interface?

We have default forward turned on. If I turn off default forward, what will that do? We add a WDS registration for each client unit. Also, you may have mis-understood my question… should I run the sys routerboard upgrade command and the sys check-disk command on the AP too???

ALSO, We run 3.x on 133c very successfully but we must not include the NTP package.

Thanks again

Also, you mayh
