Can I Use A Wired Ethernet Connection Instead Of Wi-Fi?
Yes, you can use a wired Ethernet connection instead of Wi-Fi if you’re experiencing connectivity issues. A wired Ethernet connection is generally more stable and reliable than Wi-Fi, and it can provide faster speeds and lower latency. To use a wired Ethernet connection, you’ll need to connect your laptop to your router or modem using an Ethernet cable.
