Yes, my R510 AP is still on the 200.7.10.2.339 firmware version. I can try opening a ticket on the myLennar website, and see what type of response I get from them. In the ticket wording, should I be pushing them to contact Ruckus about resolving this firmware-related speed/connection issue? I assume Ruckus would consider Lennar as a large, important customer, and wouldn't want Lennar to turn to one of their competitors for their smart home APs if Ruckus appears to be unable/unwilling to solve a self-inflicted firmware issue with the APs they have been selling to Lennar. While Lennar has been fairly responsive to customer feedback/complaints, I'm sure they'd rather not have ANY complaints --- and would likely have limited patience on a resolution.
One other question -- I noticed the recent release of 200.7.10.202.92 firmware for the R510 AP --- does this newer firmware release still have the same speed/connectivity issue as the earlier 200.7.10.2.339 firmware release that my AP is using? In other words --- do I gain anything by upgrading now, or should I just wait indefinitely for a some future 200.8.x firmware release before I upgrade?
