My tablet stopped connecting after an update last month. I reset network settings and it worked again. Updates sometimes change Wi-Fi preferences. Keeping a note of your network password helps. Restarting the router also helps when devices won't reconnect after updates.
My iPhone lost Wi-Fi after a recent update during my mom's birthday party, and I couldn't share photos. I searched for the apple customer service phone number but ended up resetting settings manually. It worked after I cleared network configs. Tech updates can cause random glitches, so knowing basic troubleshooting steps saves time when you need devices to work for important moments.
