Ok Nick,
That RSSI looks fine..the closer to 0 the better your Received Signal Strength should be.
It's perhaps not the best thing to look at in isolation though. Can you do the following please ?
About this Mac > More info > System Report > Network > Wi-Fi and report back with your Signal/Noise figures under your current network information in the same order that they appear.
Hi
Pendlewitch - thanks for the posts; I knew a little about RSSI (Received Signal Strength Indicator) but just started to look at my own laptop; from my understanding,
dBm is a decibel power ratio referenced to 1 mWatt, i.e. 0 dBm = 1.0 mW, so that the negative numbers indicated signal strengths below that level (and of course these are logarithmic, so a 3 dB change is a doubling or halving of the signal power). Thus, for signal strength the better values approach 0, while for noise, values heading toward -100 are desirable for a better S/N difference.
SO, I'm getting about -62 RSSI in my den (one room away from my router); next to the router, -42, i.e. 100x the signal power which is quite an increase; my Signal/Noise numbers are -68 dBm/-88 dBm, thus a 20 difference - probably OK but not great - would of course be much better near the router.
Now for those going through this same analysis, the quoted listing below (from
HERE) might be of use. I'm in the middle in my den, so distance from my router (which is an AirPort Extreme on 802.11n) and likely RF interference accounts for the difference. But hope this helps others better understand these acronyms - Dave
> 40dB SNR = Excellent signal (5 bars); always associated; lightening fast.
25dB to 40dB SNR = Very good signal (3 - 4 bars); always associated; very fast.
15dB to 25dB SNR = Low signal (2 bars); always associated; usually fast.
10dB - 15dB SNR = Very low signal (1 bar); mostly associated; mostly slow.
5dB to 10dB SNR = No signal; not associated; no go.
