Hotspot + External radius, High latency.. low throughput?

by rahulmkhj » Fri Aug 31, 2012 1:49 pm

Dear folks,

I'm going through a weird problem. I'm using RB1100AHx2 with hotspot setup. And using external radius server for AAA. Everything works fine with 2-3 users authenticated. But, as more users login. The latency goes very high. for example, 8.8.8.8 goes to 600-700ms, while in general it goes till ~40ms and also from within the router latency is normal. And this issue is not just with hotspot interface, but all of the 13 interfaces available on router. When I tried testing speed from some other non-hotspot interface, I get only 2~3Mbps while total available bw on wan is 40Mbps.

What I've tried so far is, created manual queues for bandwidth shaping & everything works fine.

And another issue is with mail.yahoo.com. That won't resolve if hotspot is enabled. While no issue with hotspot disabled. I've tried enable/disable remote dns requests.

I'm using ROS version 5.20.

Thank you,

Rahul..

I'm also facing similar problem with Hotspot + external Radius manager.

- DNS latency goes high when hotspot user has high utilization .

haven't you contacted DMA Softlab support? They can be helpful more than anybody else, in regard of their application.

Its not DMA related issue. Its just a radius server (probably residing on your lan/same subnet). There must be some configuration issue or network design fault at your end. Try following.

- First thing First. Upgrade your ROS to latest release that is 5.25 or preferably 6.x Hopefully it will solve your issue related to queues,
in v6, *) fixed queues - router could become unresponsive when configuring queues;
- Do strict monitoring via using RESOURCES , also Goto PROFILES and see what section is eating the CPU
- Make sure there is no virus flooding floating on your network. As HOTSPOT uses default gateway of your mikrotik router, then you must monitor users traffic for junk traffic.
- Reset to factory default, and re configure all your settings.
- Its common that some times troubleshooting takes longer time/downtime then rebuilding new one, specifically in Mikroitk where configuration can be done just in few minutes.
