-50 dBm | Excellent | This is the highest signal strength level that can be achieved in real-world conditions. If you manage to achieve an RSSI value of -50, you should have absolutely no trouble enjoying your internet connection to its full potential. |
-60 dBm | Very good | While not perfect, an RSSI value of -60 is still very good, and most people who don’t know what RSSI is would never guess that their signal strength could be any better. |
-70 dBm | Good | With an RSSI of -70, you should be able to enjoy most online activities without any major slowdowns and connection drops. From time to time, you may notice that a video is buffering a bit longer than usual or that a file taking a while to download, but that should be the extend of your problems. |
-80 dBm | Low | This is where things start to get bad. When your RSSI drops to -80, it’s highly likely that your download and upload speeds will suffer considerably, and your latency with them. Sending emails or browsing the web shouldn’t be a problem, but don’t expect to enjoy online games or high-definition video streaming without major issues. |
-90 dBm | Very low | Most people would find an RSSI of -90 unacceptable for anything beyond the least bandwidth-intensive tasks. At this signal strength level, you are guaranteed to encounter frequent connection drops and issues with lost data packets. |
-100 dBm | No signal | The more your RSSI nears the value of -100, the closer you get to not having any signal whatsoever. |
