I live in Gainesville, Florida, USA. We recently had hurricane Irma come through the SE USA and destroy lots of stuff. My power was out for a while but when it came back my Internet access, through a cable modem, did not work. The cable company is run by idiots and couldn’t figure it out.
The good news is I was able to tether my cell phone to my Omnia to provide Internet access to everything in my house. I was amazed at how well it worked and how easy it was to set up. I tried two ways, both of which worked nicely. One way was to use my phone as a hotspot. I went to the Wireless menu in Luci, selected radio 1, ran a scan to find my phone hotspot and clicked Join Network. The radio then is a client to that network and an access point for my wireless network.
The second option was USB tethering. When I plugged the phone in, a new network interface USB0 was magically defined. I went to Network/Interfaces configured that for DHCP and use as the default route. When I started it everything in house was back on line without any further configuration.
I decided to use USB tethering because that kept the phone charged and everything online. I want to thank OpenWRT/Project LEDE/Turris for being so easy to use and helping to keep me sane during this event.
