My cable guy set up a fancy router for me several months back and it has a 3G and a 5G connection. For some reason, the 5G connection often disappears for hours or days at a time, but always comes back on its own. I would think if it was something I was doing or a setting, I'd loose all my connections, not just the 5G... so maybe it's a hardware issue? Any tech savvy folks know where I could possibly start troubleshooting this?
