Connecting Router & Computer with Cable for Faster Gaming & Download Speed: 65 Mb/s Fiber Optic

Best answers

Can I connect my computer to the router with an Ethernet cable instead of a broken USB Wi‑Fi adapter, and what cable/ports do I need?

Yes—if both the router and the PC have RJ45/LAN sockets, you can connect them with a standard Ethernet cable (RJ45 plugs on both ends), which should be more stable than the broken USB Wi‑Fi adapter [#17361462][#17361499] Any LAN cable matching those sockets will fit; if you only need to run it along the floor, buy a ready-made cable in the needed length [#17361499] If the cable must go through a wall, a factory-terminated plug may not fit through a small hole, so either drill a larger opening or crimp the plug yourself [#17361499][#17361538] The current slow downloads are consistent with the damaged antenna/Wi‑Fi setup, and the cable should work much better [#17361519]

    Hello, I have a computer (7 years old), it sticks, I play games on it, it never even had a format :D 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!

    Cable in hand, plug in and find out. You have a free slot.
    Do you have the possibility to assemble such a cable? Or buying a new one.

    Do both devices [router and computer] have free RJ 45 sockets?
    You can find what the socket and plug look like on the web. And how to connect.

    Added after 7 [minutes]:

    You have a free socket in the router, I marked it in blue with an arrow:

    We are waiting for the video with the image of the computer sockets.
    Maybe due to the lack of a LAN socket for it, it worked on USB, which is unlikely.

    The back of my computer https://youtu.be/coLq5peltlw this cable is there because I have two similar to this one, but I don't know which one. And this is the back of the router, could you tell which inputs? And buy this cable what you provided?

    Added after 32 [seconds]:

    Ok and you will mark the computer?

    I hope that it is not more than 100 m from the router to the computer, it worked without a cable. The question is whether you will drill through the wall while installing the cable. In the case of a ready-made cable of a suitable length, the plug will not pass so easily, the hole must be of the right size to fit the plug. This is where the advantage of self-assembly of the plug is. But maybe you will find a friend who will earn you a plug with a special device, do not forget about more plugs when earning a cable. But that's where it has to pass through the wall.

    Yes, they will fit, terminated with RJ 45 plugs.

    For me it is not 100 m, I do not even know if it is 20 m :D and not through walls, it will drag on the ground. I have already found a cable, but it is too short :( 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?

    Added after 1 [minutes]:

    And if I had to go through the wall, would I run into any problems?

    Added after 3 [minutes]:

    And in the case of 65 mb / s about 1 m in 10 s is it normal :( ?

    Problems can be with drilling with impact in reinforced concrete, there are no problems with bricks or hollow blocks, it depends what it is made of and how thick the wall is. Remember that no one would trip over your cable and kill it. On the Internet you will find on YouTube how the RJ 45 cable end is made.

    This is normal without an antenna.

    It should be OK on the cable.

    You can always buy something like a flash drive that allows you to wirelessly connect your computer to the router, I used it myself and recommend it

    Earning the tip only then if the cable passes through a hole in a reinforced concrete wall, it is difficult to drill such a "huge" hole so that the plug can fit.
    If it does not go through the wall, you can buy a cable with plugs ready [ready] and with a small margin in length, and no problem.

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

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)

  1. Get a Cat5e/Cat6 RJ45 patch cable long enough for the route.
  2. Plug one end into any free LAN port on the router.
  3. Plug the other into the PC’s RJ45 port, then test your speed. [Elektroda, krzysiozak, post #17361462]

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, post #17361536]
