Imagine this: You rent a nice little apartment but don't have Internet there.
One day, you discover you can get a wireless signal and even the password. You try everything you can think of with your wireless card, but cannot get on.
You just might need some updates for your wireless card.
Someone gives you the download information for these updates, and you go visit a friend who has Internet to download them.
At first you cannot get on your friend's Internet like usual. It takes you quite a while to figure out what you did to it earlier while trying to get on the other network, but finally, --- well, before you figure it out, it turns out that just wiping out and resetting fixes everything.
You get back to your place and happily mess around with installing the new updates. Unfortunately, they don't seem to work.
You pass this information on to your technical expert, who emails you a link for a new download. However, you are not at your own computer, so...
...You go back to visit your friend with the Internet again, in order to get the new download. Unfortunately, whatever you did to your wireless card while installing the new updates that did not work for it at your place apparently have made it not work anywhere.
You are definitely stuck between a big rock and a very hard place, because to try to get On at your place, you have to get On somewhere else to get important new stuff, but you can't get On somewhere else because you're trying to get On at your place. Not to mention that you never know, when you leave one place, what the On status at the other place will be.
How can life be so ironic and so funny!
