I saw a post on the RT Yahoo Group - https://groups.yahoo.com/neo/groups/.../topics/103700
- that showed how to use your computer as an access point or router using commercial software.
I like the idea & posted the following:
Thanks for the idea. Windows 7 & 8 includes Wireless Hosted Network virtual WiFi run from the command prompt. Here's a tutorial: Create a Virtual Wireless Router With Windows
I used this free GUI interface instead: BrainByteZ » WLAN Hosted Network Manager
My iPod could access the internet via my laptop using the laptops standard wireless connection to an access point and also via the laptop through an old Blackberry Curve tethered via USB. I had to turn on sharing on those primary connections to the internet and had to stop the program before exiting otherwise it would continue running in the background.
I have a DD-WRT flashed router used as a repeater in the van and also a 3G router but I think there could be occasions when this "virtual access point" will come in handy. For example, some coffee shops or campgrounds require that you click "OK" or "Accept" on a their web page to get internet access and I can't do that with the repeater but would be able to do that with my laptop and then let other devices like my iPod access the internet via the laptop. Sometimes the laptop sees those connections whereas the iPod, with its less powerful network interface, doesn't see those signals.
