Wireless Access

Hi,

I bought an IAP-205 for our office and for WIFI (read: web browsing) access in general it works fine and the connection is stable. However, we have this gaming tradition on fridays where the office joins in for some fun. Since we got the IAP we've got quite big packet loss and the connection is quite unstable, unplayable at times. The issue is there when we do normal LAN gaming (not over the Internet) which leads me to believe it's something to do with the access point. It doesn't seem to matter if we're on 5 or 2.4 GHz, and connection protocol (n or ac) don't make a difference either. In the administration interface it says that all signals are strong and that there are no issues with the WIFI.

How can i debug this? Is there any idea or pointer as to what might be wrong?

Thanks a lot!

I suppose so, "Broadcast filtering" is set to "ARP"

What version of Aruba Instant?

How many clients on that access point?

Hi,

There are 5 clients right now. 2 of them are kind of active, but basically mail and browsing

Version: 6.4.2.6-4.1.1.11_52666

Thanks

Can you do a constant ping to your default gateway?

How many SSIDs are there?

Do you mean SSIDs in general in the air where i am, or that the IAP has?

My SSID is "MP", and it's the only one the IAP provides

Are you having performance issues on that client right now?  Typically it is easy to show performance issues with dropped pings.

I'm having performance issues right now, but i don't seem to get dropped pings

Performance with what application?

I'm just CLI pinging my ISP gateway and one of these gaming servers we connect to. I get stable ping and no dropped packets, BUT, if i connect to the server it's unstable hell more or less

Gateway:

289 packets transmitted, 289 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 3.431/10.838/399.446/23.050 ms

Gaming server:

288 packets transmitted, 288 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 17.158/22.514/30.322/2.239 ms

Have you tried to do anything else like surf the internet or a speed test?  Try other applications...  Typically if the client can reach the default gateway and ping that, it verifies the quality of the wireless network.  Do you have any bandwidth throttling configured on that user on the IAP?

The problem has persisted just that i haven't prioritized it. I tried another access point now to the same network so one client was on the IAP and the other on another one. The IAP client had the same type of issues as previously described, but the other one had no issues. When the other client also was on the IAP, it had the same issues.

I can't find a lot of information about this but it would be really nice if somebody could shed some light on what could be wrong. It's like waves of packet loss and high ping that appears about every second minute, so it's not a steady packet loss.

There are quite a few reasons why this could be happening.  Someone like like should look over your tech support and your network diagram and narrow it down.  It would be too hard to guess with the limited information provided on the forum.
