Wireless: Intermittent connectivity Troubleshooting Steps.
Resolution
If you experience bad unit performance like intermittent connectivity, please consider this following best practise steps:
- Please upgrade firmware of the SonicPoints to the latest one. To do it kindly go to the Diag.html page of your firewall (http://<ip-address of firewall>/diag.html – example - http://192.168.168.168/diag.html), scroll down to the wireless section and click on “Update All SonicPoint’s Firmware”.
- Stuck in provisioning mode? Unplug, reboot and plug back in.
- If you have WLAN bridge to your internal LAN, please unbridge it and set fixed IP’s for WLAN users.
- Perform RF Analysis to understand if there are any interferences. If yes, please set channels accordingly for best wireless environment.
- High noise environment might cause stop of passing beacon packets. Decrease noise sensitivity level. To do so please go to the Diag.html page of your firewall (http://<ip-address of firewall>/diag.html – example - http://192.168.168.168/diag.html), scroll down to the wireless section and set Noise Sensitivity Level to Extremely Low.
- Go to SonicPoints and press configure button on the right hand side, next to the desired SonicPoint. On Radio settings disable Short Guard Interval and Aggregation. On Advanced tab: set Preamble Length to Short. The Beacon Interval value depends on the number of VAPs. For each VAP you add you need to increase Beacon Interval by 100. Reduced fragmentation and RTS threshold to 2304.
- It is not advisable to use the same SSID for the different 802.11 radios, as clients with tri-band cards may experience disconnect issues – name them separately.
