🌐 Having WiFi issues?
Here’s how to troubleshoot before you call us!
First, take a look at your ONT (the small white box where your fiber connects). If you see 3 green lights with only one blinking, you’re good — that means your fiber internet is reaching the ONT just fine. The issue is somewhere between the ONT and your WiFi router.

Here’s what to try, in order:
1️⃣ Reboot your WiFi router
Unplug it from the wall, wait about a minute, then plug it back in. Give it up to 5 minutes to fully come back online before testing your connection.
2️⃣ Check your ethernet cable
Make sure the cable running from your ONT to your router is firmly plugged in on both ends and seated in the correct ports. A loose cable is a surprisingly common culprit!
3️⃣ Update your router’s firmware
If your WiFi is still acting up — dropping out, slowing down, or behaving inconsistently — your router may just need a firmware update. Log into your router’s settings (usually through a web browser or its app) and check for any available updates under the settings or administration menu.

Still stuck after all that? Give us a call — we’re always happy to help! 📞
