I am currently running into the problem of wireless connections on our SonicWall SonicPointNi WAPs dropping client connections. I have researched the problem with changing as many settings as I possibly can and yet the device continues to drop clients.
To give you some background we have 4 SonicWall SonicPointNi wireless access points all connected to a SonicWall NSA 220 firewall that is also the wireless controller. We are broadcasting two SSIDs, one for our office's primary users and a guest SSID. I completed a wireless spectrum analysis and placed the WAPs on channels in the 2.4 GHz range on channels 1, 6, 11, and 6 respectively where the two devices on channel 6 are in complete opposite ends of the office building to prevent overlap of the two devices.
Now, what I saw during the times of the heaviest load (btw 35-50 clients connected)was that users would be constantly dropped from the network and have to repair their wireless connection in order to reconnect.
I first saw the recommendation to change the AP to broadcasting in G mode only with setting a beacon interval to 400ms and I have set the power settings on all of the devices to minimum to minimize any wireless overlap but yet clients are still dropping.
So here is my question to the group, are there any recommendations to further troubleshoot this problem?
