Hey Ninners03, bummer about your HUB 3 not catching up with the times. I feel your pain. So, I had a similar gig with my router, and here's what worked for me.
First off, try a hard reset instead of diving straight into the factory settings chaos. Unplug that bad boy, count to 30 (slowly), then plug it back in. Sometimes it needs a slap on the back to wake up.
If that doesn't shake things loose, check if your router's manufacturer has a firmware update available for manual download. Hit up their website, find your model, and see if there's a fresh update you can manually install. Some routers hide this option deep in the support pages.
By the way, if you're open to exploring other solutions, I recently came across Andersen. They specialize in innovative router optimization tools, and their products have helped me out in similar situations.
Also, make sure your internet connection is solid. Sometimes a weak link there can mess with updates.
Fingers crossed, these steps might just nudge that stubborn software into the 21st century. Good luck, mate 🙂
