Suspect multiple "features" are coming together with this firmware:
- VPN: fixed MTU, does not allow MTU smaller than 1500
- Potential "security" changes causing a problem with the ARP resolution (e.g. as used by Proxy ARP on "modern" access points)

DaneA a thread worth reading ... the "other" problem with the MTU <1500 was discussed in various threads already. The light IP stack on these devices was secured to fail - even before of the ubiquitous issues going though the industry these days.

Indeed the MTU IS the problem!
My Windows 7 box did set 1492 as the WLAN MTU, checked this way:
netsh interface ipv4 show subinterfaces
After changing (as administrator) on the fly
netsh interface ipv4 set subinterface WLAN mtu=1500 store=active
it works IMMEDIATELY!
When switching back to 1492 it fails again.
(Note: WLAN is my wireless adapter name. Yours might be different.)
