FAQ
TL;DR: For 65 Mb/s fiber, use a wired RJ45 Ethernet; runs up to 100 m, and "Yes, they will fit, terminated with RJ 45 plugs." Expect steadier gaming and faster downloads than damaged Wi‑Fi. [Elektroda, krzysiozak, post #17361499]
Why it matters: For PC gamers on 65 Mb/s fiber, Ethernet fixes slow downloads and lag from broken USB Wi‑Fi adapters.
Quick Facts
- Standard copper Ethernet works reliably up to 100 m; a ~20 m run is well within spec. [Elektroda, krzysiozak, post #17361499]
- Cat5e supports 1 Gbps up to 100 m; plenty for 65 Mb/s fiber. Cat6 adds headroom. [Fluke Networks, 2023]
- Use a free RJ45 LAN port on the router and the PC’s Ethernet socket. [Elektroda, krzysiozak, post #17361462]
- Through concrete, an RJ45 plug may not fit; crimp after pulling or drill a larger hole. [Elektroda, krzysiozak, post #17361538]
- A broken Wi‑Fi antenna severely cuts throughput; wired stabilizes speed and latency for gaming. [Elektroda, krzysiozak, post #17361519]
Which Ethernet cable should I buy for 65 Mb/s fiber?
Buy a pre-made Cat5e or Cat6 Ethernet patch cable with RJ45 plugs on both ends. Both fit typical routers and PCs. For 65 Mb/s, Cat5e is sufficient and cost-effective. “Yes, they will fit, terminated with RJ 45 plugs.” [Elektroda, krzysiozak, post #17361499]
Where exactly do I plug the cable in on my router and PC?
Plug one end into a free LAN port on the router. Plug the other end into the PC’s RJ45 Ethernet socket. The highlighted router LAN port in the thread shows the correct place to use. [Elektroda, krzysiozak, post #17361462]
Will a wired connection actually improve my gaming ping and downloads?
Yes. Ethernet removes Wi‑Fi antenna and interference issues, giving steadier latency and throughput. As one expert put it, “It should be OK on the cable.” Expect smoother play and consistent download speeds. [Elektroda, krzysiozak, post #17361519]
How long can my Ethernet cable be without issues?
Use up to 100 meters of copper Ethernet without needing repeaters. Your estimated 20 meters is well within limits. This length will not bottleneck a 65 Mb/s service. [Elektroda, krzysiozak, post #17361499]
Do I need to crimp RJ45 connectors myself, or can I buy ready-made?
Buy a ready-made patch cable when you don’t need to pass through tight holes. Crimp a connector only if the plug cannot fit through a drilled opening. [Elektroda, krzysiozak, post #17361538]
Are my speeds normal? 900 KB takes ~10 seconds on 65 Mb/s.
No. 65 Mb/s is about 8 MB/s theoretical throughput. A 900 KB file should finish in under a second on a good link. Your result indicates severe wireless limits; a cable should fix it. [Cloudflare, 2023]
How do I connect my PC to the router with a cable? (3 steps)
- Get a Cat5e/Cat6 RJ45 patch cable long enough for the route.
- Plug one end into any free LAN port on the router.
- Plug the other into the PC’s RJ45 port, then test your speed.

Any safety tips if the cable runs across the floor?
Secure the cable to baseboards or use floor cable covers. Avoid walkways to prevent tripping and cable damage. Plan a tidy route to protect the cable and people. [Elektroda, krzysiozak, post #17361519]
What if my computer has no Ethernet/LAN port?
Use a USB Ethernet adapter or install a PCIe network card. Some PCs rely on USB for networking if no LAN socket exists. Wired still beats a damaged Wi‑Fi adapter. [Elektroda, krzysiozak, post #17361462]
Which cable category is enough—Cat5e or Cat6?
Cat5e supports 1 Gbps up to 100 m, easily covering a 65 Mb/s connection. Cat6 is fine too, offering extra headroom for future upgrades. [Fluke Networks, 2023]
Do I need a crossover cable, or will a normal patch cable work?
Use a standard straight-through patch cable. Routers and modern NICs support auto‑MDI/MDIX, so crossover wiring isn’t required. [Cisco, 2021]
Should I buy a new USB Wi‑Fi adapter instead of running a cable?
You can. A user recommended a USB Wi‑Fi “flash drive” style adapter. However, for gaming stability and consistent speed, Ethernet remains the better choice. [Elektroda, Gumiś_7, #17361536]
but to the point. I don't know anything about it, but in order to have internet, I need to connect an "adapter" that receives the internet via usb. However, I broke off his antenna and I have the impression that it works poorly in games, etc. when I download something that is about 900kb, it takes 10 seconds. Too much for me, downloading the game is all day. I have a 65 Mb / s optical fiber. I have an idea to connect the computer to the router with a cable (apparently more stable). What do you think about it? Here is a video of my router: https://www.youtube.com/watch?v=Sp3cb-b3VKA. I would be grateful for a link and where to connect it, best regards!
but when I plugged it into the computer, it entered the same with the router, so it should be no problems when I have a longer one?
