Wireless Doesn’t Work in Ubuntu 10.10

For the longest time, I couldn’t figure out how to get my wireless to on my laptop. I could enable and disable my wireless card, but I could never scan and view available wireless channels. After searching many forums, I came across an article that suggested this.

rfkill unblock all

After you run this command, disable and enable your wireless card. If your problem was similar to mine, then you should be able to see wireless channels and connect. I’m not sure exactly why this works, but it worked for me. Feel free to explain if you know why this solution works. I am curious.

I hope this helps someone out. I’m very thankful I was able to come across the solution.

Rename Files in Windows 7 using the Command Prompt

I came across a situation where a client of mine needed a whole batch of pictures renamed to display “underscores” instead of “dashes”. For example, I needed the following to be changed:

W-Lawther-4311-1263.jpg
W_Lawther_4311_1263.jpg

Going through each individual file and manually changing each dash to an underscore would be painstaking. I did some research and found a very simple solution to this problem.

ren ?-???????-????-????.jpg ?_???????_????_????.jpg

Open up the Command Prompt (Start->Run->Type: cmd)
Navigate to your directory using the ‘cd’ command and display the contents of your directory using the ‘dir’ command. Here is an example of the process I went through.
