Yes, the /etc/exports syntax is sensitive to breaks or spaces.  There should 
be a single space between the exported directory and the client's hostname or 
IP address and no more.

Hmm ... if your NFS configuration works over wired ethernet, but not over 
wireless, this could point to a lower network level problem.

I tend to use static IP addresses on both endpoints to simplify checks and 
configuration, but if you use hostnames check reverse name resolution is 
correct and adjust your /etc/hosts on both ends, check the DNS configuration 
on your LAN and check the client/server IP allocations are as they should be.

Temporarily disable firewalls on both ends and check connectivity and access 
to NFS ports 111,2049 on the server.

Check firewall logs/rules on the wireless router and configure accordingly if 
they are blocking. 

Finally, make sure hostnames/IP addresses are correctly reflected on NFS 
configuration at both ends.
