A couple of months ago, we dropped off the first round of laptops for Brown County Career Resource Center graduates. Today was the next hand-off.

Huge shoutout to Brown County Career Resource Center for everything they do for this community. These graduates have worked hard to get here, and we're just glad we could play a small part in what comes next. We are so excited to see what you do next!

Help us congratulate the graduates! 🎓

Quick one: if everyone in your house is home and the internet feels sluggish, try restarting your router before you call anyone.

Unplug it, wait 30 seconds, plug it back in. Fixes more than it should.

Quick Tip!

If your router is more than a few years old, it might be the reason your internet feels slow, even if your plan is fast.

Try moving it off the floor, away from the microwave, and to a central location in the house: cheap fix, real difference.
