Hello I am a Lennar Home customer and after a power outage my Ap’s refuse to connect to the internet from the switch. They power up fine and broadcast Wi-Fi but no internet. I tried using an old AirPort Express I have from the switch no dice. Then I used an old switch I had from a previous home and it working just fine now. As I believe we have lifetime warranty on our hardware I would like a replacement switch so I can continue to use my AP’s in our ceiling.
Based on your description 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.

I attempted to find the switch IP and could not do so, I am a little techy but this is way outside my level of expertise. I find it hard to believe this is a realistic expectation for normal consumers who bought a residential home that has this stuff in it to troubleshoot. I would prefer for you to send me a new switch and I will send this one back so you so you can fix it. I am beyond lost here.
