Best Way to Test Stability and Reliability of WiFi Connection

Hi all,

I have an important video call in a few days, and I want to test the best combination of Wi-Fi card and device location to ensure my video doesn't freeze as it randomly does most days. What's the best way to test both the reliability and stability of my connection?

A web search for "wireless stability linux" will turn of a number of articles.

This looks like an excellent starting point.

Have you tested with a wired connection to verify that the freezes are definitely related to the wireless signal?

There are lots of factors.

2.4 or 5 GHz WiFi?

How many wireless devices are on your LAN? Mesh network or multiple APs?
- Turn off any device or at least their WiFi if not necessary during your call. It depends on hardware but more devices the slower the speed.

How many other 2.4/5 GHz devices like cordless phones, baby monitor etc are in your house?
- These devices typically output more power then a WiFi signal which can effectively slow down or "jam" the signal. Turn them off of move your computer to a "safe" distance where the signal strength is good.

How many other APs are close by and on the same channel?
- This will affect your bandwidth if the signal strength is strong. Try changing channels.

How fast is your internet download/upload speed?
- Are your speeds fast enough for video conferencing? I did not mention wired devices but being the only computer on during the call will ensure you are using maximum bandwidth. Depending on which software you are running using less resolution i.e. high-quality versus high definition will require less bandwidth. And of course switching to wired versus WiFi will be faster...

Is your computer really fast enough (CPU etc ) and does it have enough RAM for video calling?

I'm sure there are more but at least it is a start.

If I really needed a connection I might try a few things.

One is try to connect wired, and use a few file transfers.

If you must use wifi then might consider a phone program to scan wifi signals.

Look at settings for ones that can provide better speed and correct distance. Plenty of web pages talk about how to configure your wifi settings to include channels and spectrum.

Set router for this protocol if able to. Q settings.

I'd remove security if in home not subject to nearby hackers.
