Wireless adaptor conciderations
When concidering a wireless usb adapter concider this:
It needs to be as sensitive as possible, at the lowest price.
offcoarse the utilities controlling the card are also important.
In sweden i had to buy one of those wireless usb devices,
so i made a comparison, price against sensitivity,
and the canyon CN-WF518 was the clear winner on paper.
The rest was about 3-400 Krona whereas this one was 250.
In europe as opposed to amerika, transmitteroutput is limitted.
Here they range around 15 dBm output (more is better) and -80 dBm reception (more negative is better)
