Network question about 2.4GHz and 5GHz bands.
Network question about 2.4GHz and 5GHz bands.
Hello everyone, I wanted to share what I've found. My ISP uses coaxial cables for internet, which means I can't just change my router to a dual-band model that supports both 2.4 and 5GHz. Instead, I need to create a bridge between the connections. In short, my ISP only offers one frequency at a time—either 2.4 or 5GHz. Since some devices in my house don't work with 5GHz, can a dual-band router that bridges both frequencies still deliver both signals without major slowdown? Thanks for your help!
I usually stick to 5GHz unless I’m right next to the router. I’m also puzzled about why my ISP only offers 2.4 or 5GHz bands. Do you have both routers in your setup?
The issue is that I'm paying for a 120/20Mbps connection but only getting up to 20/10 on Wi-Fi (full speed just on Ethernet). I need to boost the speed, but the main router is causing problems with the Cisco EPC3925.
It seems you're using a single ISP-supplied modem or router in one device. These are often not ideal, but since you didn't specify what it is, I'll assume it's fine. 2.4GHz and 5GHz operate on separate frequencies, which explains why your old phone struggles with the 5GHz band indoors while your PC connects to both—because it receives both signals, providing AC1200 speeds from your router. If you wanted better performance, using your own modem/router would be a smarter choice.
Right now there’s nothing, so I’m wondering if a dual-band router would speed up the connection for streaming, downloading, and regular browsing. Maybe it could also act as an extender, though it’s more of a flat device than a full home setup—could be too much or not enough.
Upgrade to a newer router and replace the ISP model. The latest devices offer two antennas—one for 2.4GHz and another for 5GHz. These operate independently, so they won’t interfere with each other. 5GHz provides higher speed but has a shorter range and struggles to pass through walls. It generally experiences less interference since it’s less common in homes. My current 5GHz router is centrally located and covers most of the house, though it may lose signal when I step outside.
The device that takes the coaxial cable is the modem. If your internet service provider offers an all-in-one modem/router, consider purchasing your own modem and router. Connect the coax to your personal modem, then link a RJ45 data cable from the modem to your router. You’ll have both 2.4 and 5GHz options, and you’ll own everything without paying any rental charges.
