just always assumed Ruckus's QA team would catch this bug which I have know since Summer of 2019 when I installed a few APs for some clients and noticed to speed issues and reverted back to 200.6.x firmware for my clients. Then noticed a trend from people owning Lennar Homes having issues I tried to get a few of them to revert back to the firmware. I have a few of them open tickets since they have support. I don't generally need ruckus paid support since my own APs that I got was dated Nov of 2015 the R710 which I got and ran standalone firmware til they announced unleashed firmware in 2016. I never had issues with Ruckus firmware til Summer of 2019.
Anyway, I pushed others to open tickets since I did not want to pay for support for an obvious bug fo report to them a bug. Anyway, eventually, Michael here on support escalated my ticket that I opened so I did not have to pay for a support contract. Anyway, in January I had to find time to work with their support to do iperf3 tests.
I know the bug doesn't impact everyone from what I can tell it only impacts certain conditions which is why Ruckus support wasn't able to find the bug initially in a lab. I believe it requires certain RF conditions, but I can't say what conditions.
Yes, doing tests with speedflex is unreliable when you are doing it on the same AP. You have to do it on a different AP that you are logged on to.
As for their engineer team, they need to get their heads out of their #$#$# since for a while they kept sayingi it's a speed test issue even when using iperf3 and not a performance issue.... ugh... and so finally someone knocked some sense into them. I really hope they fix it.
I know Ruckus R510 can be bought cheap sometimes on eBay from Lennar Home owners who decided to abandon them. ... I bought some for some friends for around $110 each.. and R610 for around $135-$150..
R500 are not impacted from the bug from what I can tell when using iperf3. Only Wave 2 APs are impacted..
In the mean time I recommend 200.6.x firmware for now for R510, R610, R710..
R720 seems to have a bigger issue with 200.6.x and greater.
Fastest firmware was 200.4.x for me on an R710.. but I think 200.6 is a little bit slower.. but acceptable for now while waiting for a fix.
