Just to make sure I'm following correctly, the latest driver has fixes for the 2230 adapter but not the 6235 as covered by this topic? :/
I have the following Intel system (from the EPP no less) which I hope ought to make it easy to source a configuration to replicate failure. I'm considering alternative wireless/bluetooth devices at this point...
NUC KIT D54250WYK
SSD 530 SERIES
6235AN NETWORK INTERFACE CARD
The wireless router is a Linksys E1200 but I've had the same connection dropout with an Apple Airport Extreme. All other devices connected to the router are fine, 3rd-party USB wifi dongles in the NUC included.
