My wife and I lost our internet connection. It took a couple to three days to get hold of our ISP and have it fixed. Since I prefer to use my desktop computer for the internet, I took a crash course in how to use my cell phone to connect another device to the internet via the phone. I used a USB cable as it was easier, but you can also connect wirelessly.
Of course, this uses data from your cell phone, but if you have one of the "unlimited" plans and don't do any real serious internet work (gaming, streaming movies, etc.) it shouldn't be any problem. It also may be necessary to have "Hot Spot" capability on your cell phone plan.
For those of you not familiar with this, just do an internet search for
tethering or
hot spot. It's pretty easy to do in a pinch should the need arise.
