Hi!

I tested my Wi-Fi reception. It is in Swedish and the words translates to "Speed, Quality, Signal". Is quality 0=good? Signal -83=good or bad. Is it dB or what?
Can any of You with great knowledge interpret this for me.

Best regards

Doc

Your RSSI level is not terrific. My iMac sitting right next to the AP reports -15 dBm. Anything less than -70 dBm would typically be considered a weak signal.

Hello, barbu!

Thanks for that. RSSI. Wonder what that stands for. But it has to do with my Wi-Fi. Signal is not my strongest knowledge. But then I have to improve my signal that is for sure. Thanks.

Hello expede,

The RSSI measure the power of the WiFi signal. A value of -83dBm is quite low, but the really important thing is to compare RSSI with the Noise level. The noise level depends upon your radio frequency environment, but in most residential settings it would not likely be less than -90 to -95dBm. So an RSSI=-83dBm and a Noise level of, say, Noise=-90dBm, is not a great signal-to-noise ratio.

You can find both your RSSI and your Noise levels by opening the Wireless Diagnostics app's Scan window and finding your router (the bold highlighted one) and reading the RSSI and Noise column values. For instance, right now my values are RSSI=-40dBm and Noise=-90dBm for a signal-to-noise ratio of SNR=50dBm. This is a very good signal to noise ratio, as these numbers are logarithms and not direct ratios.

I suspect you need to either move your router closer to your MP or you need to get another extender router to improve your WiFi RSSI.

Good luck,
Solouki

For info, hold down Option key, then click the Wifi icon on the menu bar, can also see the RSSI and Noise value.
