At the office we had a client that thought hiding the SSID helped security. Since our rep was on the line and a big contract I suggested this unit -> http://hakshop.myshopify.com/products/black-usb-wifi-adapter-with-5dbi-antenna-realtek-8187l-chipset
So with the tool in hand, we proceeded to connect to their hidden network and easily get past WEP in about 2 minutes.
http://www.howtogeek.com/howto/28653/debunking-myths-is-hiding-your-wireless-ssid-really-more-secure/ covers this again.
When you are ready to be secure, try it with the SSID broadcasting and WPA2 AES personal security.
Every time I boot the PC I have to re-enter my wireless connection settings as it forgets them from the previous session. I do this by going to Manage wireless networks in the Network and sharing center and clicking Add - Manually create a network profile. Then complete the rest of the form including both tick boxes (start automatically and even if not broadcasting). Then it all connects fine. But when I turn off and reboot I go back into Manage wireless networks and my network is no longer there.
Running Win 7 x64 professional.
Using a nano Edimax wireless usb dongle.
The network I connect to has WEP security and has a hidden SSID.
My previous network from another router I cant delete from Manage wireless networks. It disappears till I reboot then its there again.
I can only connect to the network by adding it manually. If I try and connect using the icon on the toolbar and selecting 'Other network' then entering the SSID and password it wont connect.
I am using windows to configure my network connection (zero something maybe...) not the Edimax software.
