Ruckus R650 WiFi Speed Suddenly Slows Until Reboot

josephkim — Fri, 13 Jan 2023 20:57:27 GMT

Hi,

I recently purchased a Ruckus R650 (purchased through authorized dealer) running Unleashed Firmware v. 200.12.10.105.129 with a very simple single access point configuration.

Everything initially looks good (350+ mbps speed). However, the network will randomly and non-deterministically suddenly slow to below 1mbps. The rest of the network (hardwired LAN computers) is functionally completely normally with full speeds.

The AP will stay in this bad, slow state until I manually reboot it. Then, the AP is instantly back to normal (350+ mbps) speeds until it randomly gets back into the bad state in 1-3 days.

Initially, I thought there must be a hardware issue so I purchased another R650 for testing, but the new device is exhibiting the exact same behavior.

Any ideas? I suppose I can return the devices, but I had heard great things about Ruckus (unfortunately, my experience has been pretty bad thus far...).

Hi Joseph, I suggest for you to upgrade this AP to the last firmware "200.13.6.1.319"

I actually downgraded from that firmware because I thought maybe it was causing the issue.

The issue is present on both versions.

I have an older R610, and that access point has zero issues. Both my R650s are affected (same exact location for the AP, just swapping out the access point).

As a test, I moved one of the R650 devices to Ruckus Cloud, and it seems to be operating flawlessly. Therefore, I believe the issue to lie with the Unleashed firmware. My R610, which is also running Unleashed, is working properly.

I have opened a support case with Ruckus.

I have the similar bug on my R650 unleashed.

After about 2 months of running I realized my uploads were slow from 500Mbps to 150Mbps and I had to reboot.

I found a post about it on reddit and unfortunately it says it hasn't been applied to Unleashed yet.
This was a year ago, but the problem seems to be still there.

MR 28.6 finally fixes slowdown issue with AMPDU : meraki (reddit.com)

As an example, a freshly rebooted MR56 with an iPhone 13 on a clean 80MHz channel does 700-800mbps TCP throughput but eventually drops to 300-400mbps after a few days of uptime.
Ruckus fixed this a few months back in some of their firmware images (but not Unleashed yet unfortunately). Meraki finally addressed this in 28.6.
This doesn’t affect pure WiFi 6 OFDMA mode but even WiFi 6 clients frequently operate in WiFi 5 MU-MIMO mode so they will be affected too.

After a running time of 43 days, upload is slow down again today. I tested with iperf3 and it dropped to 150mbps. The problem occurred only with tcp upload. tcp download, udp download and udp upload are fine.
After a reboot it's back to 550mbps.

Hello Jungyu_park, thanks for sharing it.

We have a new unleashed version - 200.14.6.1.179

You might want to try this version.

Thanks for letting me know that information.
There doesn't seem to be a fix for this in the release note, but I'll give it a shot.

The 200.14.6.1.179 firmware also had this issue and I eventually stopped using ARC.

The current uptime is 32 days and there are no symptoms of slowdown yet. The feature will obviously add one layer in the middle to classify the packets, and I think this is where the problem occurs while processing the packets.

Hi Support

We have R650 5 APs. We have the Current firmware version 200.14.6.1.199. We are facing suddenly slow internet browsing and video call drops on Wi-Fi. But at the same time on LAN, all browsing and video calls are smooth. We have facing this last 15 days.

Hi @Pushpendra
Could you please open a support case so that we can check the AP condition along with the client stats at the time of issue. This will help us to identify the issue.
