OK, Since Root is out I just rooted my LG Marquee and installed the Wifi Tether app (available in the market) and it works like a charm. LG-Marquee info
Click the "Downloads" link and always choosing the newest version, unless it doesn’t work. So follow the link below for the newest version!
I am using 4G and WiFi Tether 3.1pre4 on my LG Marquee to update this thread! WOOT WOOT!
Once it’s installed, open the tethering app and hit menu. Choose settings then change device profile to LG Marquee. It will auto by default after that. Then start tethering. It will have an error but it works. LG Android Phones
