Channels - one way to optimize your wireless network speed

802.11x wireless networks work by transmitting data on one of 13 channels.

If your neighbour's network is broadcasting on the same channel as yours you may experience significant performance problems.

The quickest way to make sure you're not affected by this is to use a wifi network detection/discovery tool. I used to use Netstumbler, but it doesn't work properly on Windows 7. So I found that the easiest way is through the Windows command line.

You do this on a computer connected to your wireless network.

1. Open a command line
2. Type: netsh wlan show networks mode=bssid
3. Look for your own network name and find the channel number.
4. Then make sure it is not the same as any other network in the list.

Want to download youtube playlists?

Sometimes you will want to download every video in a youtube playlist.

Here's an example playlist page for an amazing Qigong course

It's very easy to do, and here are 3 solutions you can use:

1. For Linux, or any platform that support Python: rg3 youtube-dl.

For Windows users, I recommend downloading ActivePython.

2. For Windows, FREE: Free Studio

3. For Windows, only the PAID version does playlists: TubeSucker (great name, lol)

Remember, don't download copyrighted videos, kids!

Enjoy!
