Hi all, Reviving this thread as we’re still seeing this issue but I find it surprising that it seems to only be Cisco customers who seem to have encountered it. The common complaint we get is “it works fine at home” so the finger is being pointed at our infrastructure.
Has anyone found a fix other than downgrading drivers? I still haven’t been able to get hands-on time with a broken client to collect packet captures; it seems the 2012 MacBook Air works fine (but Lenovo systems do not).
