wish it had of been my first thought.
Ditto, I skipped that part and assumed she had a service disabled that she couldn't get started.
If buying an adapter, consider where the PC is going to be. An internal card with a fixed external antenna is good if you have a PCI slot open or a USB adapter will work great if you have an extra port. Both of these will need the computer positioned for best signal. If it's in a cabinet or if you have walls or other obstructions, especially metal ones , in between you and the signal, you may get a very weak connection. Both of these conditions applied in my case.
Since you may not want to put your computer in a window, an alternative is to get a card or USB adapter with an antenna that can be positioned for best signal. One with at least 3-4 feet of wire will give at least some "tweaking" for best signal.
I'm using a cheap $35 USB adapter on a 3 meter USB extension cable ($10) with the adapter taped up in a window. It works great and I get 90% signal to and from the router I connect to which is two mobile homes away.
Hopefully, that's a bit more helpful.
Wow, what a long-winded reply. I got my typing practice in for today.
