I recently acquired several 328's to upgrade my monitor system. One objective was to make sure they were all connecting to my wireless access point. During this process, I have noticed some flakiness with a couple of speakers not enabling the USB Wi-Fi dongle to connect to the wireless access point. I attempted many troubleshooting steps (swapping dongles, etc) which yielded random results.

Bottom line: There can exist a fundamental issue with the connectivity of the dongle/cabinet that will not allow the Wi-Fi dongle to function. This is not just limited to speakers either as this solution was first applied to my CS18 which was having the same issue of a specific Wi-Fi dongle not functioning.

Solution: Obtain a USB extension cable and plug that into the speaker and then plug the Wi-Fi dongle into that. Boot the speaker and the wif-fi dongle should start to blink again. Verify that everything is working, shut down the speaker, remove the extension cable and plug the Wi-Fi dongle directly into the speaker. Boot the speaker and the dongle should function again.

My experience is that I have a couple suspect cabinets. One cabinet, that originally had no problems until I swapped dongles, has failed to initiate the Wi-Fi dongle a couple times now. Repeating the solution stated above would once again, resolve the issue. Will need more time to determine if this becomes a long term issue.

Anyway, I hope this information is helpful to someone at some point. I haven't seen anyone post with these types of issues, but now I have experienced it on two different PreSonus products. Perhaps a rare engineering/assembly design flaw.
