What I find interesting is that with all the traveling I do...and using WIFI in numerous locations in various states...
The most current driver actually works the best, and nearly without a single problem anywhere.
I suspect this comes down to the WIFI router with which folks are connecting. Each router can have its own "uniqueness" when it comes to handshaking with various devices. My T100 has worked in literally dozens of hotels, airports, restaurants, other homes, businesses, as well as this base location - all with the .187 driver. What I have seen is that in at least some of those locations, the security setup varies - typically WPA2 with a passcode at times, but usually the other locales have WEP with open access.
I suspect there might be some "quick judgement" about the .187 driver version being the source of issues. I'd me more suspect of the security setups on routers, as well as things like reserved or DHCP IP's, and even firewalls that can be "uncooperative" with some WIFI connections.
Based on my extensive use in extensive locations...the evidence I've seen is that the .187 T100 WIFI adapter driver is operating just fine.
