Is the adapter detecting the network ?
See what happens if you disable wireless security in the router temporarily.
No, the adapter is not detecting any network from anywhere (even at Starbucks free wireless internet, or any free hotspot area), i live in an apartment that have Wi-Fi.
The conclusion is, even there is 10+ wireless networks surround me about 3 m far, still can't detect any.
about Disable wireless security in the router, i don't quite understand which, or exactly how to it? you mean, set the setting by default?
