Recently acquired a new Lenovo X240 and Windows 7. Latest Intel drivers after numerous problems including intermittent drop outs, slow speeds and often timeout when connecting to a wireless access point. Latest drivers appear to have significantly helped the slow speeds which is an improvements.
Unless I disable the UAPSD setting on the adapter the slow association and association time outs still persist but at least this work around stops me wanting to ditch this machine and the AC7260.
Trouble is turning off all the power saving features canes the battery and significantly reduces the time I can run on the batteries which is still quite frustrating and should not be something I have to do.
Looking at the forums issues have been on going for months. Is there a single place where the current issues with these cards are documented with all known workarounds but more importantly the current issues list and approach to fixing. Appreciate most manufacturers are often unwilling to admit to faults but this appears to have been going on for a while and a merging of issues, fixes and workarounds with some open dialogue at scale to capture issues might help resolve this problem faster
