we had a power outage that lasted 5 seconds. when the home system rebooted our internet coverage was extremely slow and dropped intermittently. we also were unable to re-connect to conf calls via Zoom. I spent a long time troubleshooting with AT&T and we were able to get the system running back to high speed to the router.. but the wifi is intermitent and some apps aren't connecting. I'm guessing a setting must have changed from the outage as it's almost as if certain ports aren't working. Any help would be much appreciated as my wife and I both work from home and depend on a reliable internet connection.
Please confirm if the issue is happening while it is connected to access points or when it is connected to ISP router.
Please follow out the next steps.
Connect the computer to the ISP router with the ethernet cable. Run the speed test, and confirm if your speed is stable and search for websites, make sure you have no issues.
You can perform the same step on wireless by connecting the computer to the Wi-Fi / SSID coming from the ISP router. (Note: Not the Wi-Fi coming from the access points.)
If you have confirmed that internet issue is stable while you are connecting to the ISP router, but the issue persists while you are connecting to the access points or the switch, it looks like your Switch (ICX7150 Switch) may be booting from the secondary partition ( Note: Secondary partition contains the routing code) which is causing the bad connectivity issues. This could happen after multiple power outages, please follow up the next guide.

Note: if you have access to the Unleashed Dashboard and the Switch can be seen from there, it may look like the following image, ICX7150-C12-Router instead of ICX7150-C12-Switch, now before starting the steps of the guide, I will advise you to cable the computer directly to the Switch, since you will have a better connectivity than if you connect via wireless.
After fixing the issue of the Switch booting from the wrong partition, please perform an upgrade to the code 08095g UFI and upgrade both partitions primary and secondary with the switching code file named SPS08095gufi.bin, take into consideration that is the Switch is running a code lower than 08080 you need to upgrade twice, from the code you are to 08080f and then the recommended code 08095g UFI.
