General Network Troubleshooting Tips for macOS - Micro Center
<main> <article class="userContent"> <p>If you're experiencing issues with your internet on your Mac, there are quite a few things you can try to fix those problems.</p><p>The first thing to try is to reboot your router/modem to make sure they aren't causing the issue. A simple reboot could fix the problem within a minute. If your computer is plugged directly into your router with an Ethernet cable, make sure the wire is securely in the back of your computer and router/modem. You can also try another port on the back of your router. </p><p>If you are getting an invalid password message when trying to connect to your Wi-Fi, remember that wireless passwords are case sensitive. You can typically find default passwords and SSIDs (network names) written on a label on the router. If you try that and the password is still incorrect and you are not sure what it is, contact your <strong>Internet Service Provider</strong> for assistance with retrieving your wireless password.</p><p><br></p><p>If those quick tips don't help, there are a variety of methods to try to get the Mac back online:</p><p>1. Check your other devices that are connecting to the same network. If other devices are experiencing issues or not connecting either, contact your Internet Service Provider.</p><p>2. Reboot the Mac first by opening the Apple menu and selecting <strong>Restart…</strong> from the menu. Do not reopen windows upon logging in. Try the connection again after restarting.</p><div class="embedExternal embedImage display-large float-none"> <div class="embedExternal-content"> <a class="embedImage-link" href="https://us.v-cdn.net/6031942/uploads/editor/pz/xok3atghyu8y.jpg" rel="nofollow noreferrer noopener ugc" target="_blank"> <img class="embedImage-img" src="https://us.v-cdn.net/6031942/uploads/editor/pz/xok3atghyu8y.jpg" alt="xok3atghyu8y.jpg" height="180" width="320" loading="lazy"></img></a> </div> </div> <p></p><p><br></p><p>3.

If you're using Wi-Fi but your Mac has an ethernet port, try using an ethernet cable and plugging directly into your router instead. If the issues go away when using an ethernet cable, and none of the previous steps fixed your wireless issues, it is possible there are hardware issues with your wireless adapter.</p> </article> </main>
