Wireless network not operating at 802.11n 130 Mbps speed (only running at 802.11g 54 Mbps): I won’t go into too much detail- but the resolution was to change the security from WPA to WPA2 (seems crazy to me that the web interface doesn’t make this incompatibility clear).
ESXi / NFS problems: My virtual machines kept dieing and there were a lot of NFS events in vSphere "Lost connection to server x mount point y mounted as z". This must be related to the network maintenance over the last few weeks but I’m not quite sure why.
