If slow internet and intermittent Wi-Fi stressed you out during virtual school last spring, there are some things you can do now to make sure you dont have the same experience when classes start in the next few weeks. To make sure your internet is fast enough and your Wi-Fi can handle the course load, do these three things before the bell rings. If you have an old router, you may have the same one from your cable company for years and years you want to replace that. Then you plug in or place little pucks where ever you need a stronger signal. The more little pucks you need, the more itll cost you.
