Terrible ping times between wireless / wired subnets

  • 772

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.

  2. Try disabling "Enable Aggregation" if you are using the 802.11n radio on the SonicPoint. That caused me lots of grief when iPads/iPhones were using the network. After unchecking the box, the effect was immediate.
