desktop wireless internet connection

[brod298]

Hi everyone,
I have ATT internet connection through modem and Ethernet cable for my desk top and wireless for laptop. Recently our community management installed Xfinity box in each apartment and I can use it for laptop as it's much faster than ATT. because I don't like paying both I was wondering how can I connecte my desktop PC to that Xfinity box. My desktop PC and ATT modem are in a different room than Xfinity box.
Thank you

Ways to connect your desktop to the Xfinity box in the other room​

Pick whichever fits your apartment layout and comfort level:
1) Add Wi‑Fi to the desktop (simplest)

• Check if your desktop already has Wi‑Fi: Settings > Network & Internet. If you see “Wi‑Fi,” you’re set—just join your Xfinity network using its password label.
• If not, buy a USB 3.0 Wi‑Fi adapter (look for Wi‑Fi 6/6E, AX1800+). Plug it in, install the driver, then connect to your private Xfinity SSID (not the public “xfinitywifi” hotspot) for best speed and security.

2) Use a Wi‑Fi bridge/extender with Ethernet port

• Get a “Wi‑Fi extender/bridge” or a small travel router that supports Client/Bridge mode and has an Ethernet jack.
• Place it near the desktop, connect it to the Xfinity Wi‑Fi during setup, then run a short Ethernet cable from the bridge to your PC. Windows will see it as a normal wired connection.

3) Powerline networking (Ethernet over electrical wiring)

• Buy a HomePlug AV2 powerline kit (two adapters).
• Adapter A: plug into a wall outlet near the Xfinity box (not a surge protector), connect it to a LAN port on the Xfinity box with Ethernet.
• Adapter B: plug into a wall outlet near your desktop, then Ethernet to your PC.
• Speeds depend on your building’s wiring, but it’s often very stable and easy.

4) MoCA (Ethernet over coax), if you have coax jacks in both rooms

• Use a pair of MoCA adapters—one by the Xfinity box, one by the desktop—then Ethernet from each adapter to the devices.
• Reliable and fast if both coax jacks are on the same line. You may need a MoCA filter/splitter; check building rules first.

5) Run Ethernet

• A flat Cat6 cable along baseboards/under rugs is the most reliable and cheapest if a direct path is feasible.

Quick Windows steps (once connected)​

• Windows 10/11: Settings > Network & Internet > (Wi‑Fi or Ethernet) > connect; then run a speed test to confirm stability.
• If you plan to cancel AT&T, test the desktop connection for a few days first.

Questions to help me tailor this​

• What version of Windows is on the desktop (10 or 11)?
• Does the desktop show a Wi‑Fi option already?
• Do you have coax jacks or just power outlets in both rooms?
• Are you allowed to plug a device into the Xfinity box’s LAN port?

- Windows 10 on desktop
- No Wi-Fi option
- not sue about coax jacks, how do they look like?
- yes it's allowed to plug PC - wired connection

Best ways for your setup (Win10 desktop, no Wi‑Fi)​

Pick one of these to reach the Xfinity box in the other room:

1. USB Wi‑Fi adapter (fast + simple)

• Buy a USB 3.0 Wi‑Fi 6/6E adapter (AX1800 or better).
• Plug it in, install its driver, then connect to your private Xfinity Wi‑Fi network (not the public “xfinitywifi”).
• Windows 10: Settings > Network & Internet > Wi‑Fi > Show available networks.

1. Wi‑Fi bridge/extender with Ethernet port (PC still “wired”)

• Get a Wi‑Fi extender or small router that supports Client/Bridge mode and has an Ethernet jack.
• Set it up to join your Xfinity Wi‑Fi, place it near your desktop, then run a short Ethernet cable from the bridge to the PC. Windows will see Ethernet.

1. Powerline (Ethernet over electrical wiring)

• Buy a HomePlug AV2 kit (2 adapters).
• Adapter A: wall outlet near the Xfinity box → Ethernet to a LAN port on the box.
• Adapter B: wall outlet near desktop → Ethernet to PC.
• Notes: Plug directly into wall (not surge strips). Speed depends on apartment wiring.

1. MoCA over coax (if both rooms have cable jacks)

• Use two MoCA 2.5 adapters: one by the Xfinity box, one by the desktop, Ethernet from each device to its adapter.
• Often the fastest/wire-like if the coax outlets are on the same line. You may need a MoCA filter/splitter—ask management if the building already has one.

1. Run Ethernet

• A flat Cat6 cable along baseboards/under a rug is cheap and most reliable if you can route it cleanly.

What does a coax jack look like?​

• Round metal connector on a wall plate with a single pin in the center and external threads (you screw a cable on). Often labeled “Cable” or “TV.” Ethernet jacks look like oversized phone jacks (rectangular, click-in).

Next steps I recommend​

• Easiest/quickest: USB Wi‑Fi adapter or a Wi‑Fi bridge with Ethernet.
• If you prefer “wired” stability and have cable jacks in both rooms, go MoCA; otherwise try Powerline.
• Since you’re allowed to use the Xfinity LAN ports, you can test by temporarily moving the PC (or a laptop) to that room and plugging in to confirm speeds before buying gear.

Want me to suggest specific adapter types (USB Wi‑Fi vs bridge vs powerline/MoCA) based on your apartment layout and budget? If you can, let me know:

• Do you see those round threaded “Cable/TV” jacks in both rooms?
• Rough distance between rooms and whether there’s a hallway/baseboard path for a flat Ethernet run.
