Most likely you are missing drivers for your wireless device. You can use Dell.com to find required drivers.
One degree of latitude is 69.06 miles. With this information, and knowing that there are 5,280 feet in a mile, this becomes a simple arithmetic problem.
No problem at all. It was a piece o' cake.
It has various meanings, e.g. space or liberty to do something (as in: 'he gave me the latitude to sort out my problem'); it is also used topographically to refer to map positions along a horizontal axis, e.g 'New York is at x degrees latitude'
Make sure that your PS3 supports type of the wireless network you are using including security if you have one.
It's the problem with your wireless broadband/wideband. I have never come across this problem.
Either there's a problem with the network or the player needs an update
No problem - just use wireless security. (WEP WPA or WPA2)
From my personal experience with the Latitude series by Dell, I can tell you straight up: Don't buy it. There are an outrageous number of bugs on the Latitude, even on my Windows 7 Latitude by Dell. To start off, over time if you leave your laptop on for a certain duration of time, I found that the USB would stop functioning. I made sure it wasn't just my laptop. According to about 6 of my other friends who have a Dell Latitude, they all have the exact same problem. Secondly, there is a horrible overheating problem with it. My problem was really bad, despite it having little memory usage taken up with 4 gigs of RAM, it managed to burn so bad that the area that the heat sink is at has completely burned up, and is bent from melting. And that's only some of the bugs. Straight up, don't buy a Latitude.

There are numerous reasons for your laptop not to pick up your wireless connection. Check the following and see if they solve your problem. 0.5 Check if your wireless router is switched ON! 1. Check if your laptop has a wireless card in it (old models might not have). 2. Check whether your wireless network is hidden. If it is just set it to visible. 3. Check that you are in the range of the wireless network. 4. Check the network configuration of your laptop. 5. Check if the wireless adapter on your laptop is not disabled. 6. If any of these don't help call a technician :).

That's OK, it's not a problem. West longitude is commonly written as a negative number.It's much easier for computers to store and manipulate coordinates in that form.For the same reason, you'll occasionally see south latitude written as a negative number.
