We were running an AP-2000 access point and seperate x86 MikroTik router at this one tower site, and it worked good.
We're now trying out the RB532+CM9 MikroTik Router/AP combo box at that site, and, while I'm impressed at how much snappier my connection at home feels while connected to this AP/Router combo, I am seeing spikes in ping times to not only my wireless client antenna, but for other customers. (Ping tests were done from the wired end - which actually plugs into a 5GHz backhaul.)
I'm seeing ping spikes of up to atleast 125ms ever 3 - 5 seconds, somtimes it'll go maybe 15 - 25 seconds before you see it spike like this.
I like to play Quake2, and I can watch the Quake2 "netgraph" to see when it happens. (It's not the gameserver nor my route - its the AP/Router combo, because I also see these spikes when pinging the AP/Router combo from home - or from work on the wired side.)
My game just like everything else on my connection moves along alot quicker with this setup, which I love very much, however, these ping spikes cause my game (and everything else I imagine) to stutter for approx. 50ms (I'm guessing). It's not fun for me nor my opponents to see that.
Otherwise, my connection to this tower is doing so much better... now if we can just iron out the ping spikes with it.
Ok, here are the details:
- Wireless clients to this tower are all 802.11b
- CM9 wireless card is running in ap-bridge mode set to 2.4GHz-B running on Frequency 2447 (Chan 8 I believe)
- Supported B rates - I have all of them checked
- Basic B rates - I have all of them checked
- we're not doing encryption, WDS, or Nstreme; we just have a 15 dBm omni antenna on the tower broadcasting this 802.11b signal.
- we've got the wireless client antennas configured for static private IP's, but the customer is configured for DHCP (gets a public IP)
- we're doing RADIUS authentication on the wireless and dhcp; we authenticate on the wireless by their antenna's MAC address and we do the same for the customer's PC/Router with DHCP.
- the wireless interface (wlan1) has its ARP set to reply-only, and we're putting the wireless client antenna MACs in as static ARP entries, while the DHCP server is setup to add the ARP entry.
Now, the ping spikes and/or overall connection quality seemed to improve some after I enabled all Basic B rates. (This was with all Supported B rates already enabled by default.)
Is there anything left that I can try out here to solve this?
