This may be especially usefull to Gamers.
I have just been informed by a friend at Fastcomm who has just completed an extensive IPWireless course of the following:

The Signal to Noise Ratio (SNR) (you guys call it signal strength) shown on your Modem in percentage is directly proportional to your Ping times.

Basically when the SNR is below 40% all Bitrate correction routines kick in and these alone utilize approx 80 ms of the ping time.
Once the SNR goes above 45% these routines are no longer used and at 45% one can expect a ping in the order of 40 ms.
As your SNR improves further your pings will drop.

So if one had to use an external Antenna like the one currently advertised with a 22 dBi gain which should give you approx a 3 times improvement, your 20% SNR should achieve 50% to 60% and it would be very interesting what your ping time would be.

All we now need is for someone to test this [;)]

sign me up yo... i'll get that 1.5k antenna from powerband... i wonder what dbi gain i'll get.. hmmmmm

or, i have to wait... *sigh*

does this mean my ping time will stabalize as well? cause i get ping spikes between 300-600 sometimes (1 in ever 30 pings i do) pushing up my average at about 156ms after 100 pings

This sounds promising.
Now all we need is one of those towers in Somerset West. I have a large underused back yard [:D][:D][:D]

Telkom - South Africa's Handbrake to progress.

Until anyone (myself included) can connect these antennas to a modem, here are some stats that I keep on ping times...

It has only been running for the weekend, so it is probably still a bit early to come to any conclusions?

How does the snr % ratio relate to the db amt we see in the mysignal util?
