A generic speed test measures throughput and latency to its own server; it cannot prove that the route to a GeForce NOW, Amazon Luna, or another provider’s data center will be responsive.
Check four measurements—bandwidth, ping (latency), packet loss, and jitter—against the service’s current requirements for your device, resolution, and frame rate. If the result is poor, change one local condition at a time (for example, Ethernet instead of Wi-Fi, 5 GHz instead of 2.4 GHz, or VPN disabled), retest, and then play long enough to look for delay, stalls, or image-quality changes.

What “good enough” means for cloud gaming
Cloud gaming sends your controller or keyboard input to a remote computer and returns a live video stream. That makes the quality of the route to the provider’s data center more important than the headline speed on your broadband plan. A connection can download quickly yet still feel sluggish if packets take a long route, arrive unevenly, or are lost and retransmitted.

It also supports Power over Ethernet (PoE, PoE+, PoE++) for powering devices like IP cameras, VoIP phones, and wireless access points, ensuring fast and reliable network performance.
- Bandwidth: the sustained data rate available to the stream. More demanding resolutions and frame rates require more.
- Ping or latency: round-trip time between your device and the provider’s data center. Lower values reduce the delay between an input and the resulting image.
- Packet loss: data that never reaches its destination. Loss can produce freezes, visible compression, or sudden quality reductions.
- Jitter: variation in packet arrival time. A low average ping can still feel inconsistent when jitter is high.
NVIDIA Support describes a good network as having no packet loss and says that low ping helps prevent a delay after you press a mouse button or gamepad. Those are vendor explanations rather than independent laboratory measurements, but they identify the characteristics your test should expose.
Start with the service, device, and stream target
Before running a test, write down the exact combination you intend to use. The same home connection may meet a service’s requirement for 1080p on a television but miss the target for a higher-resolution PC stream.
- Choose the provider. Select the service you will actually subscribe to or try. Its data center location and client requirements determine the relevant path.
- Choose the device and app. Note whether you will play through a native PC app, browser, phone, television, or handheld. Providers publish different thresholds for some of these clients.
- Choose the quality target. Record the intended resolution and frame rate, such as 1080p at 60 frames per second or 4K at 120 frames per second.
- Find the provider’s current requirements. Use the service’s official support or requirements page, because figures can change and should not be borrowed from another provider.
For example, the current GeForce NOW requirements page lists these examples for native PC platforms:
| Target | Published bandwidth example | Other published guidance |
|---|---|---|
| HD, up to 60 FPS | 15 Mbps | Less than 80 ms network latency from an NVIDIA data center; NVIDIA recommends wired Ethernet or 5 GHz Wi-Fi. |
| FHD at 60 FPS | 25 Mbps | |
| QHD or ultrawide QHD at 120 FPS | 35 Mbps | |
| 4K at 120 FPS | 45 Mbps |
NVIDIA lists other values for browsers, phones, televisions, and handhelds, so do not assume the native-PC examples apply to every client. Amazon Luna lists at least 10 Mbps sustained for 1080p. Amazon recommends wired networking or 5 GHz Wi-Fi when available and advises disabling VPNs and proxies during streaming.
Rank #2
- Cat 6 performance at a Cat5e price but with higher bandwidth
- High Performance Cat6, 30 AWG, RJ45 Ethernet Patch Cable provides universal connectivity for LAN network components such as PCs,computer servers,printers,routers,switch boxes,network media players,NAS,VoIP phones
- Jadaol cat6 standard cable support Cat8 and Cat7 network and provides performance of up to 250 MHz 10Gbps and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T/1000BASE-TX (Gigabit Ethernet) and 10GBASE-T (10-Gigabit Ethernet)
- UTP(Unshielded Twisted Pair) patch cable with RJ45 gold-plated Connectors and are made of 100% bare copper wire, ensure minimal noise and interference
- The unique flat cable shape allows for a cleaner and safer installation. You can easily and seamlessly make the cable run along walls, follow edges & corners or even make it completely invisible by sliding it under a carpet.
Those figures are service requirements, not promises. A connection just above a bandwidth threshold may still perform poorly if its latency, loss, or jitter is unstable.
Run the provider’s own network diagnostic
A provider-operated test is preferable because it measures the route that the game session will use. NVIDIA Support explicitly says it does not recommend generic internet speed tests such as Speedtest.net for this purpose: those tests do not evaluate the connection to a GeForce NOW server.
GeForce NOW procedure
- Open the GeForce NOW client and go to Settings.
- Leave Server Location set to Auto. NVIDIA says Auto selects a nearby suitable data center.
- Select TEST NETWORK and wait for the results.
- Record the reported bandwidth, ping, packet loss, and jitter. Save a screenshot or note the time so you can compare later runs.
NVIDIA warns that a VPN can prevent the client from finding the closest data center. If the diagnostic flags a VPN, an unexpected server location, 2.4 GHz Wi-Fi, or another condition, correct that condition and run the same test again.
When the provider has no built-in test
Use the service’s current official requirements and any diagnostic offered in its app or help center. A general speed test can still tell you whether your access line has roughly the expected throughput, but it is not a pass/fail verdict for the streaming route. Record the test server and time if you use one, because results to a different server are not directly comparable to the provider’s path.
Rank #3

- PoE Supported: All lengths of ethernet cord can support the PoE power supply function except 65ft. You don't need additional power supply when installing a PoE camera, which is very convenient and safe
- Wide Compatibility: With the RJ45 Connector, network cable can be perfectly compatible with computers, laptops, modems, routers, PS5, X-Box and other networking devices. It can also be fully backward compatible with Cat7, Cat6e, Cat6, Cat5e, Cat5
Interpret all four measurements
Bandwidth: compare sustained capacity with the target
Compare the measured sustained rate with the provider’s requirement for your exact stream. Use the figure as a floor, not as a score: headroom helps when other devices share the connection or when the line fluctuates. If your result falls below the stated requirement repeatedly, lower the stream target or investigate the local network before buying a faster plan.
Ping: the input-to-screen delay component
Ping is round-trip delay between your device and the provider’s data center. GeForce NOW requires less than 80 milliseconds from an NVIDIA data center. That number is provider-specific; do not present it as a universal cloud-gaming limit. A route with a lower value generally leaves less time between an input and the server’s response, while a high value can make fast games feel delayed even when bandwidth is ample.
Packet loss: missing data causes visible interruptions
Packet loss means portions of the stream or your input do not arrive. NVIDIA Support says a good network has no packet loss and a bad network has a high percentage. Any recurring loss deserves attention. It can originate in Wi-Fi interference, a local cable or router, an overloaded access link, ISP routing, or the provider’s side; the diagnostic alone may not identify which.
Recommended Free Tools
Jitter: consistency matters as much as the average
Jitter is variation in arrival time. Two tests can show the same average ping while one has much larger swings. High jitter often appears as uneven motion, brief stalls, or quality changes. Compare jitter between connection setups rather than relying only on the lowest single ping value.

Retest in a controlled sequence
Change one condition at a time so you can identify what helped. Run the provider diagnostic after every change, then verify the result in the game.
- Establish a baseline. Test where you normally play, with your normal router settings. Record all four metrics, the server selection, and the time.
- Try Ethernet. Connect the device directly to the router with an Ethernet cable if both have compatible ports. A Cat 6 cable is an optional troubleshooting aid, not a cure for a distant data center, poor ISP routing, or a provider outage.
- Compare 5 GHz Wi-Fi. If you must use wireless, join the 5 GHz network on a dual-band router when it is available. Keep the device within a reasonable range because 5 GHz generally has shorter reach than 2.4 GHz.
- Disable VPNs and proxies temporarily. Retest with them off. Both NVIDIA and Amazon identify VPN or proxy use as a potential obstacle to the preferred streaming path.
- Reduce competing traffic. Pause large downloads, uploads, backups, and video streams on the same connection during the comparison. Restore them afterward to see whether ordinary household use changes the result.
- Repeat at different times. A single run is a snapshot. Test during the hours when you normally play to reveal recurring congestion.
- Play a real session. Launch a game and use it long enough to encounter movement, camera turns, menus, and combat or other rapid inputs. Observe responsiveness, stalls, resolution changes, and audio interruptions.
GeForce NOW can be tested with a free membership before purchasing a membership, according to NVIDIA Support. That makes an actual session a practical final check rather than relying on a speed-test number.
Ethernet versus Wi-Fi: what to compare
| Comparison point | Ethernet | Wi-Fi |
|---|---|---|
| Path to the router | Dedicated cable connection; usually less affected by household radio interference. | Shares wireless airtime and can be affected by distance, walls, neighboring networks, and band congestion. |
| Test result to watch | Compare ping, loss, jitter, and sustained bandwidth with the Wi-Fi baseline. | Check whether changing from 2.4 GHz to 5 GHz changes those same metrics. |
| Hardware requirement | The device and router need compatible Ethernet ports; a cable is required. | A dual-band router and a client that supports the chosen band are needed for 5 GHz. |
| What it cannot fix | Remote-server distance, ISP routing, provider congestion, or an outage. | Those same upstream limitations remain, even with a new router. |
Choose the setup that produces the more stable provider-specific results and a better real-game session. A faster broadband tier or a new router is not automatically the answer when latency to the provider is the limiting factor.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Troubleshoot by symptom
High bandwidth, but controls feel delayed
- Check the provider diagnostic’s ping rather than the result from a generic speed test.
- Confirm that the selected data center is appropriate and that a VPN or proxy is not forcing a longer route.
- Compare Ethernet and 5 GHz Wi-Fi. If both show similar high latency, the limitation may be distance, ISP routing, or the provider rather than your local wireless link.
Brief freezes or sudden image drops
- Look for packet loss and jitter in the provider test.
- Test with competing uploads and downloads paused.
- Move from 2.4 GHz to 5 GHz or Ethernet and repeat the test.
- If loss remains on every local setup, document the times and results before contacting the ISP or service support.
Bandwidth repeatedly below the service target
- Verify that the target resolution and frame rate match the requirement you are using.
- Run the test when other household devices are idle to distinguish shared usage from an access-line limitation.
- Lower the stream target if the service allows it, then test again.
Good diagnostic, poor game session
- Play long enough to expose intermittent problems; a short test can miss time-of-day congestion.
- Check whether the in-game stream changes quality when another person starts a download or video call.
- Repeat the provider test immediately after the symptom and compare the recorded metrics.
- Remember that the diagnostic is evidence about the network path, not a guarantee of identical performance in every title or at every hour.

| Observed pattern | Most reasonable next step | Do not assume |
|---|---|---|
| Wi-Fi has higher loss or jitter than Ethernet | Use Ethernet where practical, or improve the 5 GHz connection and retest. | That a more expensive broadband plan will remove local radio interference. |
| Both Ethernet and Wi-Fi miss the provider’s latency target | Check server selection, VPN/proxy status, ISP routing, and provider status; retest at another time. | That a Cat 6 cable or new router can shorten the remote route. |
| Bandwidth is below the selected quality target on every setup | Reduce resolution or frame rate, limit competing traffic, or investigate the access line. | That low ping alone makes the stream suitable. |
| All metrics look acceptable but play still stutters | Capture the time, title, device, client type, and in-session symptoms, then compare with another session. | That one diagnostic run proves every game and device will behave identically. |
A 5 GHz-capable dual-band router with Ethernet ports is worth considering only when your comparison demonstrates a local Wi-Fi limitation and your existing hardware cannot provide a stable alternative. Do not buy equipment by default; measure first.
Service-specific cautions
GeForce NOW
Use the client’s Settings → Server Location → Auto → TEST NETWORK path. Apply the bandwidth examples in the earlier table only to the stated native-PC targets, and keep the less-than-80-ms NVIDIA data-center latency requirement with that service. NVIDIA’s tester may flag 2.4 GHz Wi-Fi or an active VPN because either can affect the route to the nearest suitable data center.
Amazon Luna
Amazon Luna’s listed minimum is 10 Mbps sustained for 1080p. Amazon recommends wired networking or 5 GHz Wi-Fi and says to disable VPNs and proxies while streaming. Use those figures and recommendations for Luna rather than treating them as requirements for unrelated services.
Xbox Cloud Gaming and other services
The available official material does not establish a current Xbox Cloud Gaming threshold here. Use Xbox’s own current requirements and any diagnostic it provides. Do not substitute GeForce NOW’s or Luna’s numbers for a service that publishes different guidance.
A printable cloud-gaming test checklist
- Service, device, app or browser, resolution, and frame rate recorded.
- Provider’s current requirements located.
- Provider diagnostic run with the correct server or automatic selection.
- Bandwidth, ping, packet loss, and jitter recorded.
- Baseline Wi-Fi result saved.
- Ethernet comparison completed when ports and cable are available.
- 5 GHz comparison completed on a dual-band setup.
- VPN and proxy disabled for a comparison run.
- Competing household traffic considered.
- Real game session checked for input delay, stalls, image quality, and audio continuity.
- At least one retest performed at the time you normally play.
If the provider-specific measurements meet its guidance and the real session remains responsive and stable, your connection is likely suitable for that particular setup. If not, the recorded comparisons show whether the next step is a local Wi-Fi change, a different stream target, an ISP investigation, or support for the cloud-gaming service.
