Lately, I’ve been experiencing slow internet during video calls and streaming. I need help understanding how strong my Wi-Fi signal is to determine if it’s the issue. Any tips or tools to measure Wi-Fi strength would be greatly appreciated.
So, if you’re dealing with slow internet during video calls and streaming, it might be a Wi-Fi strength issue. Luckily, there are a few methods and tools to help measure your signal strength.
First off, you can start with a simple method. On many devices like laptops and smartphones, there are built-in utilities that display your Wi-Fi signal strength. For example, on Windows, you can press Win + R, type cmd, and press Enter to open Command Prompt, then type netsh wlan show interfaces. Look for the “Signal” section to see the signal strength in percentage.
If you’re on a Mac, hold the Option key and click the Wi-Fi icon in the menu bar to see detailed information. You’re looking for something called “RSSI” (Received Signal Strength Indicator); the closer this number is to 0, the stronger your signal (typically anything above -67 dBm is considered good).
For smartphones, you can use Wi-Fi analyzer apps available on the App Store or Google Play Store. Just search for “Wi-Fi analyzer” and pick one with good reviews.
There are also more advanced tools designed specifically for this purpose. A popular one that I recommend is NetSpot
(https://www.netspotapp.com). It’s particularly useful as it offers both a simple way to see your current signal strength and more advanced functionality like creating visual heat maps of your Wi-Fi coverage area. This helps you determine dead zones where the Wi-Fi is weak and find optimal spots for your router to improve coverage.
When you use NetSpot, you can conduct a detailed site survey. Here’s what you might do:
- Download and install NetSpot: Head over to https://www.netspotapp.com and get it installed on your computer.
- Run a survey: You can select “Discover”, which will show you all available Wi-Fi networks, or “Survey”, which allows creating detailed Wi-Fi heatmaps.
- Analyze the data: The survey will give you a clear view of your Wi-Fi strength across different areas of your home. You’ll get to see signal strength, signal-to-noise ratio, interference levels, and more. This info is crucial for diagnosing and fixing your internet woes.
If after all these checks your Wi-Fi is indeed weak in certain areas, consider a few tweaks:
- Router Placement: Place your router in a more central location in your home, away from walls and obstructions. Elevated positions like on a shelf can help.
- Channel Interference: Routers broadcast on different channels. Tools like NetSpot can show you which channels are less congested around you, and you can switch to these within your router’s settings.
- Firmware Updates: Ensure your router’s firmware is up-to-date. Manufacturers often release updates that improve performance and stability.
- Wi-Fi Extenders: If you find dead zones you can’t avoid, consider using a Wi-Fi extender to boost the signal to those areas.
- Upgrade Your Equipment: Sometimes, older routers can’t keep up with the demands of new devices and higher-speed internet. Investing in a modern router might be a good move.
Hope this helps and good luck troubleshooting!

If you’re experiencing slow internet during video calls and streaming, it might indeed be due to weak Wi-Fi signal strength. @codecrafter gave you a solid rundown on the basics and some commonly recommended tools and tricks. While those methods are great starting points, let’s dive into a few other nuances and angles you can explore:
-
Wi-Fi Analyzer Apps Usage:
- For smartphones, apps like Fing and WiFi Analyzer (for Android) provide real-time data on signal strength, channel usage, and nearby network interference. They might be more user-friendly than what was previously mentioned.
- Consider Signal Strength in dBm as -30 dBm to -67 dBm are in the excellent to reasonable range. Anything worse than -70 dBm and you might start noticing performance issues, especially for heavy traffic like video calls.
-
Cross-Checking Devices:
- Sometimes the issue might be device-specific. If you’ve got multiple devices (laptop, tablet, smartphone), check the Wi-Fi strength individually. An older device’s Wi-Fi receiver could be weaker compared to newer models.
- Additionally, don’t forget to check your devices’ Wi-Fi settings. Sometimes switching from 2.4GHz to 5GHz can offer significant performance boosts, especially for high-bandwidth tasks like streaming, although at the cost of range.
-
Router Configuration Beyond Placement:
- @codecrafter mentioned tweaking your router placement and channels. But dive deeper into your router settings. Many modern routers offer QoS (Quality of Service) settings where you can prioritize traffic for video streaming or calls.
- Try enabling “Beamforming” if your router supports it, which directs the Wi-Fi signal to your devices, improving performance where needed.
- Change security settings from WEP (if really old setup) to WPA2 or WPA3, as outdated security protocols can limit performance.
-
Router Load:
- Sometimes the issue might simply be too many devices connected. Log into your router and check the connected device list. Smart home devices and others can sometimes hog bandwidth. Disconnect any that aren’t essential.
-
NetSpot Pros and Cons:
- Pros: Easy interface, detailed heatmaps, and comprehensive surveys, making it ideal for tech amateurs and professionals alike.
- Cons: Some advanced features, such as conducting detailed multi-floor analyses, require a Pro version.
- Alternatives to consider: Wi-Fi SweetSpots, inSSIDer, or Acrylic Wi-Fi Home. Each has its strengths, like simplicity or advanced metrics, but none offer the detailed visual heatmaps of NetSpot.
-
Physical Interference:
- Be wary of physical barriers that can dramatically reduce Wi-Fi signal. Objects like large metal appliances, microwaves (yes, they run on similar frequencies), or even dense walls can disrupt the flow.
- Clear line-of-sight between your router and primary usage areas is ideal.
-
ISP-Related Issues:
- Sometimes, the problem might not be your Wi-Fi at all but your Internet Service Provider (ISP). ISPs sometimes throttle speeds during heavy traffic times, or you may not be receiving the service tier you’re paying for.
- Conduct a speed test (via Ookla’s Speedtest, for instance) directly connected to your modem, bypassing the router, to see if there’s a significant difference.
-
Future-Proofing:
- As @codecrafter suggested, router upgrades can be a big help. Newer models like Wi-Fi 6 routers (e.g., Asus RT-AX86U, Google Nest Wi-Fi) offer better everything—range, speed, device handling. They’re a worthwhile long-term investment.
-
Professional Help:
- If after trying all these suggestions, you’re still facing issues, it might be worth considering professional help. Some ISPs offer diagnostic services to check your setup and suggest upgrades.
Finally, don’t forget to revisit all these settings periodically—what works today might not necessarily hold up as you add new devices or your ISP changes something on their end. Happy networking!
Guys, let’s not get ahead of ourselves with tools and apps just yet. Sure, you can measure Wi-Fi strength with fancy software, but sometimes the oldest tricks are the best ones.
First off, if video calls and streaming are slow, don’t overlook the basics. A lot of people forget to restart their router. Power cycling it can often fix connectivity problems caused by temporary glitches.
You might find it hard to believe, but I fixed my slow streaming issues just by changing the angle of my router antennas. If your router has external antennas, try positioning them vertically. It can make a world of difference.
@codecrafter and @techchizkid have pointed out some valid tips, but sometimes it’s not about signal strength at all. It’s about interference. Ever had slow Wi-Fi because someone was using the microwave? Yeah, it happens. Wi-Fi and microwaves use similar frequencies (2.4 GHz), so things like that can mess up your connection. If you’re seeing drops during dinner time or other peak times when everyone’s using their devices, then interference could be it.
Before delving deep into tools, here’s a quick trick:
Open your router’s admin page and check for QoS settings (Quality of Service). QoS prioritizes your internet traffic and can significantly enhance your video call and streaming quality. For example, set video streaming and VoIP services to high priority. This way, those will get the most bandwidth and be less impacted by other devices using your Wi-Fi. Just don’t set everything to high priority because that would defeat the purpose.
Another often overlooked factor is your router’s firmware. Manufacturers often release updates that improve performance and fix bugs. Log into your router’s admin interface and ensure it has the latest firmware version. This can also resolve many performance-related issues.
If you must measure Wi-Fi strength, i honestly prefer using built-in tools over third-party apps for a start. On Windows, go to the Command Prompt and type: netsh wlan show interfaces. It’ll show the signal strength in percentage. On a Mac, hold the Option key and click the Wi-Fi icon in the menu bar. The RSSI value you see gives you a rough idea of your signal strength; anything better than -67 dBm is generally okay.
Regarding advanced tools, @codecrafter mentioned NetSpot, and while it’s indeed robust, some find it complicated. An easier, more straightforward app is Wi-Fi SweetSpots (available for both iOS and Android). It’s user-friendly and shows real-time performance metrics. If you still opt for NetSpot because it does offer comprehensive features and visual heatmaps, you can download it at https://www.netspotapp.com.
I noticed some disagreement on which frequency band to use: 2.4GHz vs. 5GHz. Here’s the gist:
- 2.4GHz covers a larger area but is slower and more prone to interference.
- 5GHz offers faster speeds but with shorter range.
Switching between the two might solve your problem, especially in crowded areas or if your home’s Wi-Fi footprint is complex.
Also, consider your router’s placement. Centralize it in your home rather than having it tucked away in a corner. Elevating the router often helps. If it’s currently on the floor, move it higher, ideally 3-4 feet off the ground.
Lastly, I’ve seen people buy expensive routers thinking it’ll solve their issues. My advice: don’t. First, try adding Wi-Fi extenders. They’re cheaper and can eliminate dead spots effectively. If you realize your current router is simply outdated, then consider an upgrade.
Remember to also check your ISP. Sometimes, slow speeds during video calls and streaming are due to throttling or other server-side issues. Run a speed test while directly connected to your modem to know your ISP delivery. Tools like Ookla’s Speedtest can help with this.
One more thing before you splash out on new tech—look into the devices themselves. Older gadgets may have weaker Wi-Fi receivers. So if you’ve noted that your streaming woes occur on an older laptop or the first-gen tablet, a newer device may outperform.
Finally, if you’ve tried all these tweaks and nothing works, professional help might be the last resort. Some ISPs offer tech services to diagnose issues and suggest fixes, often as part of your service package.
Keep experimenting and don’t underestimate the good ol’ trial and error. Happy troubleshooting!
