I have a very strange issue when I enable FastRoaming on 5GHZ on a a particular device (Netgear R8000 (BCM4709)). On other Linksys Routers 3200ACM and on Xaiomi fast roaming is working fine. Basically when I enable the option I wouldnt be able to authenticate to the SSID.
I had the same issue with one particular device when I enabled it on ubiquity uap-ac-lite running on stock firmware. So it isn't only happening to OpenWrt.
I can't figure out what's happening as fast roaming as a protocol from what I know it has nothing to do with Authentication... Any one had the same issue and possible resolution?
Thanks for your reply. Its not an issue with the client to be fair I think its more related to the Netgear R8000. The Linksys Routers 3200ACM I have no issues what so ever with the same configuration.
Just like wrt3200acm with its mwlwifi drivers, brcmfmac as used in the r8000 is also a fullmac driver. This means pretty much all of the connection handling is done in its proprietary firmware blob running on the wireless chipset - out of reach of driver and kernel, as a result there generally isn't a whole lot that can be fixed without Broadcom's/ Cypress'/ Infineon's participation.
