Wifi – Terrible ping times between wireless / wired subnets

networkingwifi

I have a SonicWall router configured as follows:

P0 = Wired LAN (192.168.1.1)
P1 = Internet
P3 = Sonicpoint WAP  (192.168.5.1)
P3-A = Private Wireless LAN VLAN 1 (192.168.6.1)
P3-B = Public Wireless LAB VLAN 2 (192.168.7.1)

If a computer is on P3-A their IP address would be 192.168.6.2 and their gateway would be 192.168.5.1

If I ping any internet site (google.com) I get sub 30ms responses.

If I ping an address on P0 (192.168.1.4), the ping time varies wildly between 2ms and 2000ms – more so than not it's about ~800ms.

Any suggestions as to identify why I can ping the internet with a consistent response but can't ping the local 192.168.1.x subnet without?

I had more problems even after disabling RF Monitoring, but upgrading the Sonicwall to SonicOS 5.8.0.3 (which also upgrades the Sonicpoints) seems to have alleviated the issue.
