Yes, about 30 seconds ago :)

#mount -v -t nfs -o nfsvers=3 a6://usr/portage /mnt
mount.nfs: timeout set for Tue Oct  7 16:35:39 2014
mount.nfs: trying text-based options 'nfsvers=3,addr=192.168.1.75'
mount.nfs: prog 100003, trying vers=3, prot=6

I have nfsv4 working correctly so the urgency is gone but I'm still
curious if nfsv3 really should work over wifi as well as nfsv4.

Thanks.
