I have the same problem using Cisco Linksys Wifi USB key on Ubuntu 14.04 using wily-kernel "4.2.0-30-generic x86_64". I have reported a bug 1550915 and it was marked as a duplicate of this bug.
If someone having the same problem. I have found a work-around. I have downgraded my kernel to 3.13.0-79-generic (kernel 3.13. was the one officially released with Ubuntu 14.04), then purged ndiswrapper software and installed it again to make sure kernel module was recompiled against current kernel.
