During a troubleshooting session a few months ago, we discovered on a SonicWall NSA-250M hotfix, that after this hotfix applied, several wireless devices couldn’t associate anymore. Mainly notebooks, but smartphones and wireless HP printer could associate.
During the above mentioned troubleshooting we decided to stay with the last firmware, as the SonicWall support could not discover what was causing this problem many wireless clients couldn’t associate anymore.
Now they released SonicOS Enhanced 188.8.131.52-17o and exactly this issue is occuring. We rollback to SonicOS Enhanced 184.108.40.206-3o (or any later does the same) and the issue is gone.
Will see what SonicWall will discover when they will face loads of tickets during the next months when people with SonicPoints attached to their SonicWall environment will update to this new released firmware.
Now when SonicOS Enhanced 220.127.116.11-220 was released we started a new firmware upgrade activity, making sure, all wireless devices have the newest wireless adapter driver installed.
When the new firmware is updating the SonicPoints, again all wireless devices can’t associate and so get no IP address. Same as on the past sessions regarding this issue.
So we rolled back to 18.104.22.168-30 again, but even after the ‘old’ firmware has also been rolled back on the AP, the clients couldn’t connect. The reason was, because the device came back with all SonicPoint configuration and profiles reset. So we had to reboot with backup settings. After this all wireless clients could connect again.
Could be, that wireless Dell clients or adapter working fine with the new firmware, but we will not support such politics.
If you don’t want to run into such a situation to be forced to replace a large number of wireless devices because of future firmware updates, you better look for more serious and reliable solution vendors.
