We had a client with several sonicpoint N wireless access points based in their offices. Everything had been working perfectly for a while and then Mac OSX 10.10 Yosemite came along.
We had originally set the network up using an Apple MacBook Air running 10.9 with no problems at all. The network was stable and the Sonicwall was running the latest firmware. We then came in after updating our Mac computers to Yosemite, connected with the network and noticed our wireless was disconnecting itself automatically after several minutes. To confirm everything was working, we booted up a Windows computer and connected to the network. Everything worked well and the computer stayed connected with the wireless as expected. So an Apple Mac problem it seems.
So what did we do to resolve the problem? We performed the following steps.
It is also worth noting that Apple have acknowledged that iPads and Mac computers do not support 40mhz Wide Channel in the 2.4Ghz range.

So what did we do to resolve the problem? We performed the following steps.
- Log on to the Sonicwall
- Go to Sonicpoints > Sonicpoints
- Edit the Sonicpoint N provisioning profile that is causing problems
- Under the 802.11n Radio tab, turn off the check box for Enable Aggregation
- Go to the Advanced tab
- Change the beacon interval to 400
- We also attempted to change the power to half -3db
- Click OK to save changes
- Reboot both Sonicpoints to assign the provision.
- If this does not work select to synchronise Sonicpoints.
