My boss gave me an old wireless router that we weren't using at work. I've been mooching off of someone in my neighborhood for the past two months but the reception dropped to nothing yesterday.
I finally hooked up the router and my laptop could see it but couldn't get on it.
I called my boss at home (at 7:45) and he spent about a half hour on the phone with me. He didn't know how to fix it.
I called my co-worker and he couldn't talk. He called me back about an hour later (after I spoke to me boss); he was on the way to the store to buy ice cream for his wife. He walked me through the entire setup process from memory. We weren't done setting it up when he got to the store, so he sat in his car for another 15 minutes to finish up.
I don't make much money at my job, but the people I work with make up for every penny.
