R500 slow troughput, high latency, high packet loss

[kari_hyv_nen]

Hi! 
Today I upgraded our Ruckus R500 Wireless access points from web interface button to the latest (200.5.10.0.235) software. After that the internal network speed is very slow. We practically cannot download anything from our file server or have skype calls or anything.

While connected to internal wlan, I get these kind of ping statistics for our access points

Ping statistics for 192.168.xxx.xxx: 
Packets: Sent = 150, Received = 138, Lost = 12 (8% loss), 
Approximate round trip times in milli-seconds: 
Minimum = 2ms, Maximum = 1166ms, Average = 804ms

It does not seem to matter, to which access point I'm connected to. Signal strength is excellent (I'm less that 10ft away from the AP), the network speed is reported between 500-1000Mbps.

However, if I connect to our Guest WLAN, I get decent speeds and can ping outside network addresses with low latencies. Problem started after the upgrade. I have rebooted all the access points, but that didnt make a difference.

I'm new to Ruckus Wireless products, is there anything else I need to do after an upgrade? I have no idea where to start troubleshooting. I've opened a support ticket, but I hope that I could get some help here more quickly.

Hi Kari, I've followed this thread since it began and was wondering if the private fix is shareable, i.e. on github, or something similar? I understand if it is not. Thanks. Pyrs

Hello Peter, if you create a ticket with our Tech-Support, ask for the image associated with ER-5956 bug.  This will be included in our upcoming 200.6
release, but not for a little while yet.

ER-5956 fix is in .293. On that issue, for 802.1x WLAN, if the AAA server’s authentication response includes a “Microsoft VSA to allow encryption to be used on MPPE tunnels”,
Unleashed AP would mis-interpret it as “rate limit” policy, and will set the policy to the (wrong) value in the attribute.

Thus that’s the “slow throughput” some customer may observe. I do not know how common that attribute is set on AAA servers. If it’s popular, I guess we will learn so soon.
For now we will simply provide .293 image for those customers.

Doing some grave digging here... 
Anyways,  last year I got the private fix 200.5.10.0.293 . 
I'm planning to upgrade to 200.6.10.1.308 (GA Refresh) . Reading the release notes, 200.5.10.0.291 is the latest version that can be upgraded to 200.6.10.1.308. Do I need to downgrade first from 200.5.10.0.293 to  200.5.10.0.291 and then install 200.6.10.1.308 ?

No, check your Firmware Upgrade page (if you have Internet connectivity), and you should see an Update (200.6) is available.
