Let me try to sort out where we are, and I'll also give a little background why seemingly easy things like releasing a patch aren't so easy.
IE 11 - actually seems to work fine (see
https://forums.ruckuswireless.com/ruc... ), so the reported issues seem to be OS related (see below)
Win 8.1/IE11 - That seems to be a problem due to Microsoft dropping RC4 ciphers in 8.1 coincident with us dropping an alternate cipher due to a reported attack vector. You can add RC4 back -
http://technet.microsoft.com/en-us/li... as a workaround, and we should have this corrected in the upcoming 9.6.2 and 9.7.0 releases. Chrome/Firefox also work.
Win 8.1 RT - Nothing to report yet. The workaround is using a separate WLAN with classic PSK.
Patches...Releasing a patch (which 10's of thousands of networks could potentially load, and affecting millions of users) requires us to stop work on something else so that we can fully regression-test to ensure a happy experience. So we've got to balance the impact of that (for RT) over delaying something else (like Win 8.1 support). In other words, fixing things is comparatively quick - it's the testing that's a bear.
Clients are going to continue evolving rapidly, and so we are focusing on better long-term solutions allowing for more graceful failure modes on not-yet-supported platforms.
