We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
That being said u/pixelrogue, this could also be a channel/wireless issue too. I would also suggest using. NetSpot to check channels. Source: over 2 years ago
I've not looked in to new apps in years, I still have access to the old free version of inSSIDer but I've also used Wifi Analyzer from farproc (Android only I believe). Cannot vouch for the quality or safety of either at this point. Source: almost 3 years ago
