My JioFiber Wi-Fi Was Extremely Slow on Windows 10 — Here's How I Fixed It
My Android phone was getting around 27 Mbps from the same JioFiber Wi-Fi, while my Windows 10 desktop was sometimes getting only a few Mbps. What looked like an internet problem turned out to be much more interesting: the problem was between the Windows PC and the Wi-Fi connection.
After troubleshooting, testing and changing the problematic Wi-Fi configuration, my Windows desktop eventually reached around 33 Mbps on Fast.com, which was comparable to — and in one test better than — the speed I was seeing on my Android device.
Why I Started Investigating
I was using a JioFiber connection and noticed something strange. The internet worked normally on my Android phone, but the same Wi-Fi connection was painfully slow on my Windows 10 desktop.
At first, I suspected the usual things:
- Maybe JioFiber was having a problem.
- Maybe the router was too far away.
- Maybe too many devices were connected.
- Maybe Windows was consuming bandwidth in the background.
- Maybe the browser or Fast.com was giving an incorrect result.
- Maybe the Wi-Fi adapter in the desktop was the problem.
But there was one very important clue:
That clue changed the entire direction of my troubleshooting.
Step 1 — Comparing the Same Internet Connection
I first tested the connection using Fast.com. I deliberately compared the Android phone and Windows desktop using the same Wi-Fi network.
| Device | Connection | Observed Speed |
|---|---|---|
| Android phone | Same JioFiber Wi-Fi | ~27 Mbps |
| Windows 10 desktop | Same JioFiber Wi-Fi | ~0.6–6 Mbps initially |
This was a huge difference.
The desktop was getting only a fraction of the speed available to the phone. At one point the result was only around 600 Kbps, while the Android phone was getting around 27 Mbps.
Step 2 — Looking at the Windows Wi-Fi Properties
I opened the Windows Wi-Fi properties to see what was actually happening underneath the normal Wi-Fi icon.
The adapter information showed:
- Protocol: Wi-Fi 4 (802.11n)
- Network band: 2.4 GHz
- Network channel: Channel 1
- Adapter: 802.11n USB Wireless LAN Card
- Manufacturer: Ralink Technology, Corp.
- Driver version: 5.1.25.0
- Signal: approximately 86% in one test
Something immediately caught my attention.
The router/network itself was capable of newer Wi-Fi technology, while my desktop was using an older 802.11n USB Wi-Fi adapter.
That did not automatically explain everything, because 802.11n can still provide considerably more speed than I was receiving. So I continued testing.
Step 3 — Checking the Wi-Fi Link Speed
Windows showed a very interesting value:
Later, after the connection changed, it showed:
And eventually:
This taught me an important lesson:
A Wi-Fi link rate is the negotiated connection rate between the PC and the router. Actual internet throughput is affected by Wi-Fi overhead, interference, retransmissions, protocol limitations, router behaviour, and the ISP/server path.
Step 4 — I Checked the Adapter's Advanced Settings
Next, I opened:
The adapter exposed several manufacturer-specific settings. Among them were:
- AP Mode Force BW20
- Country Region (2.4GHz)
- Multimedia/Gaming Environment
- Radio On/Off
- Roaming Sensitivity
- Selective Suspend
- Selective suspend idle timeout
This was another important discovery.
Windows was not simply saying "Wi-Fi is slow." The USB Wi-Fi adapter had its own driver-level parameters that could influence how it communicated with the router.
Step 5 — Checking What Wi-Fi Network Windows Was Actually Seeing
I then moved to Command Prompt and used a much more useful diagnostic command:
Windows reported that there were two visible Wi-Fi networks. The JioFiber network showed:
- SSID: AirFiber-jio_s
- Signal: 98%
- Radio type: 802.11ax
- Channel: 1
This was particularly interesting.
The router was advertising an 802.11ax network, while the desktop's adapter was an 802.11n device.
That doesn't necessarily mean the older adapter cannot work properly, because newer Wi-Fi standards are designed to support older clients. However, it confirmed that the PC was not using the same Wi-Fi capabilities as a modern phone.
Step 6 — Checking the Local Connection With Ping
I wanted to know whether the problem was actually inside my home network. So I pinged the router itself:
The results were very revealing.
In one test I saw:
Minimum = 2ms, Maximum = 278ms, Average = 65ms
Later, after the connection improved, I ran the same test again. This time:
Minimum = 1ms, Maximum = 525ms, Average = 53ms
The second result had 0% packet loss, which was better, although the occasional high latency showed that the wireless connection could still experience interference or transient delays.
This is the local gateway/router. If packets are being lost or latency is jumping dramatically even when pinging the router, the problem can exist before the traffic ever reaches the internet.
Step 7 — The Problem Started Becoming Clear
At this point I had several pieces of evidence:
- Android was getting around 27 Mbps.
- Windows was initially getting dramatically less.
- The Windows PC was using an older Ralink 802.11n USB adapter.
- The JioFiber network was operating on 2.4 GHz.
- The router was advertising 802.11ax.
- The Windows adapter had manufacturer-specific advanced settings.
- The local gateway showed packet loss and large latency spikes during one test.
- The Wi-Fi link rate changed significantly during troubleshooting.
So the problem was no longer looking like a simple "JioFiber internet speed" problem.
It was much more likely to involve the Windows Wi-Fi client, USB adapter, driver/configuration, and 2.4 GHz wireless environment.
Step 8 — Testing Again Instead of Assuming
One thing I learned during this process is that Wi-Fi speed tests can fluctuate considerably.
I repeated the Fast.com test several times instead of treating one result as the final answer.
| Stage | Windows Fast.com Result | What I learned |
|---|---|---|
| Initial test | ~0.6 Mbps | Extremely poor throughput |
| Next test | ~5.8 Mbps | Connection was improving/fluctuating |
| Later test | ~6.6 Mbps | Still far below expected speed |
| Final observed test | ~33 Mbps | Major improvement |
This gradual change was actually very useful. It proved that the desktop was capable of substantially better performance and that the earlier low result was not simply the maximum capability of the PC.
What Was Actually Going Wrong?
In my case, there wasn't one magical Windows setting that could be blamed with absolute certainty.
The evidence pointed toward a combination of:
- An older Ralink 802.11n USB Wi-Fi adapter
- Driver-level Wi-Fi configuration
- 2.4 GHz operation
- Wireless interference / instability
- Changing transmit/link rates
- Packet loss and latency spikes observed between the PC and router
The most important discovery was that the wireless link itself was unstable enough to affect actual throughput.
In other words, having a high theoretical Wi-Fi link speed does not guarantee high real-world internet speed.
The Most Important Lesson: Don't Trust Just One Number
During troubleshooting, I saw numbers such as:
Yet Fast.com could show only a few Mbps.
At first that looks impossible.
It isn't.
The 600 Mbps figure is a Wi-Fi PHY/link rate, not the guaranteed internet throughput.
Actual throughput can be much lower because of:
- Wi-Fi protocol overhead
- Interference
- Retransmissions
- Channel congestion
- Driver behaviour
- USB adapter limitations
- Signal quality
- Router/client compatibility
- Internet server/path conditions
Why the Android Phone Was Faster
The Android phone was a useful "control device" in this investigation.
Since it could reach approximately 27 Mbps on the same JioFiber connection, it demonstrated that the internet service itself was capable of delivering much more than the Windows desktop was receiving.
Modern phones also generally have much newer Wi-Fi chipsets, better radio implementations and better support for newer Wi-Fi standards than an old USB 802.11n adapter.
Therefore, the phone was effectively showing me:
My Practical Troubleshooting Sequence
If I had to solve the same problem again, this is the exact order I would follow.
Check the same Wi-Fi network on a phone or another computer. If other devices are fast, don't immediately blame the ISP.
Use Fast.com or another reputable speed test and repeat the test. Wi-Fi results can fluctuate.
Look at the Wi-Fi standard, band, channel, signal strength and link speed.
An old 802.11n USB adapter can behave very differently from a modern Wi-Fi 5 or Wi-Fi 6 adapter.
Open Device Manager and inspect the driver and Advanced settings. Don't randomly change every setting.
Use netsh wlan show networks mode=bssid to see nearby
networks, channels, signal levels and radio types.
Use ping 192.168.31.1 -n 20.
Packet loss or large latency spikes to the local gateway are important
clues that the problem may be on the wireless/local-network side.
Then repeat the speed test and ping test. This makes it possible to determine which change actually helped.
Useful Windows Commands From My Investigation
1. Show Wi-Fi interface information
This can show information such as:
- SSID
- Radio type
- Channel
- Receive rate
- Transmit rate
- Signal percentage
2. Show nearby Wi-Fi networks
This is particularly useful for investigating Wi-Fi channels and nearby wireless networks.
3. Ping the router
Replace the address with your own default gateway if your router uses a different IP address.
What I Would Upgrade If the Problem Returned
The biggest hardware limitation in my setup was the old Ralink 802.11n USB Wireless LAN Card.
If I experienced this problem again, I would seriously consider replacing the old adapter with a modern, properly supported Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax) adapter.
Even better, if the desktop supports it, a good internal PCIe Wi-Fi card with proper external antennas can provide a much more reliable wireless connection than an old generic USB adapter.
My Final Result
The Turning Point
What started as a frustrating situation where my Windows desktop was getting only around 600 Kbps to a few Mbps eventually turned into a much more useful investigation of the entire Wi-Fi connection.
By examining the adapter, driver, Wi-Fi properties, link rates, nearby networks and local ping behaviour — and by repeatedly testing instead of relying on a single speed-test result — I was eventually able to get around 33 Mbps on the Windows desktop.
The Android phone had been getting around 27 Mbps, so the final Windows result showed that the desktop was no longer suffering from the severe speed limitation seen at the beginning.
What This Taught Me
The biggest lesson from this entire experience is simple:
That path looks something like this:
A problem anywhere along that path can make the internet appear slow.
In my case, comparing the Android phone against the Windows desktop was the clue that prevented me from wasting time blaming the JioFiber connection itself.
Quick Reference for Anyone With the Same Problem

- ✅ Check Receive/Transmit link rates.
- ✅ Check signal strength.
- ✅ Use
netsh wlan show interface. - ✅ Use
netsh wlan show networks mode=bssid. - ✅ Ping the router with
ping <gateway> -n 20. - ✅ Look for packet loss and abnormal latency.
- ✅ Change one setting at a time.
- ✅ Repeat the speed test after each meaningful change.
- ✅ Consider replacing an old/generic Wi-Fi adapter if necessary.
Conclusion
What initially looked like a simple case of "JioFiber is slow on my Windows computer" turned out to be a good lesson in network troubleshooting.
The most useful part wasn't any single setting. It was the process: compare → measure → inspect → test → change → measure again.
The Android phone gave me the baseline. Windows showed me the symptoms.
The Wi-Fi adapter properties exposed the hardware and driver layer.
netsh exposed the wireless environment, and the ping test
showed what was happening between the PC and router.
Finally, the speed improved dramatically, reaching approximately 33 Mbps.
If you are experiencing the same problem on Windows 10 — especially where your phone gets good Wi-Fi speed but your desktop gets only a small fraction of it — don't immediately replace your broadband connection. Start by investigating the computer's Wi-Fi adapter and the wireless connection itself.
A fast internet plan does not automatically mean every device will get the same speed. The weakest part of the Wi-Fi client connection can become the bottleneck — and systematic testing can usually tell you where that bottleneck is.
