Handling modem and router issues across long distances
Handling modem and router issues across long distances
Hello there! I'm exploring ways to relocate my router and mini server away from the main internet connection point. My ISP router currently functions as a modem, converting COAX to RJ45, while I need it placed in a different part of the house. Ideally, I'd like my landlord to add a new COAX port in the closet. If that's not feasible, I'm considering bringing the ISP router (as a modem) with the rest of my equipment.
I'm curious about using a powerline adapter between the modem and the router's WAN port. If this is viable, would it have multiple ports? Perhaps connecting one switch port on the router to a powerline adapter could work, allowing another adapter to connect to my computer. I've been thinking about this for quite some time—have modern adapters can handle GigE or 2.5GigE reliably? Also, could we link more than two devices together at once?
Any suggestions on alternative solutions would be greatly appreciated, especially since I understand someone might recommend running a direct RJ45 cable between the living room and the closet. Please let me know your thoughts!
Yes, power lines could be an option, though details matter more. It depends on whether triplets function and if multiple pairs fit on a panel. No, I wouldn’t bother with them. If you don’t have carpet, pulling up the floor, running wire, and putting it back is straightforward. You can hide the wires inside perimeter spikes so the carpet stays in place underneath. Flat or slim cables work too—though they’re not perfect. If you lack carpet, think about Wi-Fi 6E or 7 gear. These devices handle high speeds easily; routers are getting cheaper and you might find a card for your server. This isn’t the best setup, but it’s a viable alternative.
Based on what I've learned, it's unlikely. I came across information suggesting newer wiring standards like arc fault breakers might cause interference. Older setups also present problems. Electrical cabling isn't really meant for data transmission—it's surprising how functional it still is in my view. Moca could be an alternative, but it requires coax at both ends and decent wiring in the apartment. There are some limitations for technicians too. First, a Moca filter must be installed on the main cable entering the building to stop the signal from reaching the ISP's network. Second, wiring should be at least RG6 according to my understanding. Using adapters is costly. Adding more Moca devices can slow down the network performance.
@Johno Duderino When you switch the ISP gateway to “modem-only mode,” the following device must connect—likely a router. Positioning PL outside the LAN could cause issues. It’s been quite some time since I used PL, though previous setups assigned LAN IPs to each outlet. I might be mistaken, so please share your thoughts. Also, in shared living situations there’s a chance others with PL could access your network if they’re also using it. Remember, PL operates via electrical wiring. Some of your apartment’s circuits may connect to the same lines as those shared by neighbors. Regarding reliability, PL isn’t as stable as Ethernet, fiber, or coaxial connections. As for performance, many factors affect it and it can be unpredictable. I’d avoid making it the primary data path; peripheral tasks that handle interruptions are fine.
Avoid believing what’s advertised or shown online. Powerline adapters aren’t reliable. Check if your property has any additional coax connections you could use.
I think Johnt made 2 good points : - The carpet isn't a bad idea, it's probably cheaper and waaaay more reliable than powerline things . Also note that if you have a house with multiple power circuit & breaker, and that you end up with you powerline devices on two different circuit, it might just not work, as I noticed that in the past (I have to admit not recently). - Wifi 5 (AC) or 6E would be also a more reliable way to go, if their isn't so much " noise " (other APs, wifi networks, etc) around. Finally, someone else might have mentioned that (if not mistaken), but depending on the speed you get for your internet connection, maybe 2.5G isn't that useful. If you have your NAS in the closet and the other " clients " devices elsewhere, that might be different, but remember where is your bottleneck, your internet connection might be it.
