Using maximum bandwidth connections via coaxial cable for high-speed internet access
Using maximum bandwidth connections via coaxial cable for high-speed internet access
Hey there, your friend is setting up his new flat and has some coax connections scattered around. There’s a coax for internet, a TV coax (female), and another one (male) whose purpose isn’t clear—possibly old radio gear. It sounds like the ISP will install a modem when he finalizes his internet plan. The main challenge is getting fast internet (around 1Gbit) to another room without Ethernet wiring, since the flat doesn’t have any.
I’ve thought of two options that skip running cables or relying on a cheap WiFi router:
1. Use the TV coax as an extender for the modem input and place it in the desired room.
2. Purchase an Ethernet over Coax adapter and receiver, then connect it to the modem in the living room.
Both ideas rely on being able to rewire the “other” coax so it connects directly to the one in the other room. I’m not sure if those setups are feasible, though.
My concerns are:
- Are the coax cables in walls typically the same quality? Will they handle high-speed data?
- The ISP might prefer a different approach, even if you don’t notice it.
- I’ve seen Ethernet over coax devices mainly for cameras; finding a gigabit model is tricky.
If you’re leaning toward the second option and need a recommendation, do you have any specific adapter suggestions?
It’s close enough, but I haven’t had much success with WiFi stability. I might be misunderstanding things a bit, but I feel the main computer shouldn’t be connected wirelessly—especially since my friend is gearing up to stream again. I considered a PowerLine adapter, though I doubt it’s trustworthy and won’t deliver high speeds. But now I see, up to 2000Mbps could work well, which is significantly better and more affordable than what EoC can offer. Yeah, I might be overthinking it. Still interested in extending the coaxial internet connection through another line.
They claim 2000Mbps but it's actually twice 1000Mbps. Marketing exaggeration. In terms of stability, it performs much better than my home cable service. I haven’t noticed any dropped or slow connections from the powerline adapter over the past three years. People often criticize it because they buy the cheapest options and then complain later. I’m unfamiliar with Ethernet over coax and have no interest in exploring that further. Perhaps you could repurpose the extra coax cable as a pull string to install a new Ethernet cable? Just make sure it’s not permanently attached to anything. Best of luck with this project.
We remember dark theme users—black text isn’t readable. What you’re after is Moca. Here’s what you need to know:
- Moca works with the same lines as your cable provider; a filter is required on the main cable entering your home.
- Speeds can reach up to around 800 Mbps+, depending on adapters.
- It operates in half-duplex mode, which limits communication to one direction at a time.
- Only 16 Moca adapters can be connected to a network. Multiple devices can link via a switch.
- I’ve moved the modem several times; ISPs don’t complain.
- For best results, keep signal quality high—no more than one splitter between the cable and the modem’s network. If you can manage that, placement should work.
