Wake on Wireless on Mac with WRT54GL

Yes, it does work.

First, your Mac must support Wake on Wireless. Macworld article how to check if your Mac support Wake on Wireless.

Then you need a Linksys WRT54GL router and Tomato (my favorite firmware). You can also use any other router and/or firmware. Only one thing matters: your router must support Wireless Multimedia Extensions (WME), also known as Wi-Fi Multimedia (WMM). Wikipedia article.

Now log into your router running Tomato and under Advanced - Wireless enable WMM and save your changes.

Before you can test wake on wireless get your Mac’s MAC address. Once you have the MAC address put your Mac into sleep. From an another computer log into your router with a Tomato firmware, go to Tools - WOL, put your Mac’s MAC address into the MAC Address List folder and click on Wake Up.

Your Mac should wake up now :).

A notice:

Enabling Wake on Demand on your Mac means a new issue:  after your Mac goes to sleep it wakes up every two hours because of Bonjour. Here is the explanation for that (under "A comment in mDNSResponder's open source code offers some explanation").

I found a workaround to disable the every 2 hours wake up issue (notice: I didn't try this workaround yet).

How to Transfer Files Over Wi-Fi with Dropbox [File Sharing]

Dropbox sharing over Wi-Fi
We recently went through some of the best ways to share files with a nearby computer, and many of you noted that Dropbox can still be a viable syncing method, even over Wi-Fi. Here's how to set it up.

In our rundown, we noted that Dropbox, while one of our favorite services ever, isn't ideal for sharing with your friend sitting right next to you. While you can use Dropbox to share files with anyone, you usually have to upload it and download it from Dropbox's servers first (which takes longer than sharing over Wi-Fi, Ethernet, or the other sharing options we mentioned). However, if both you and your friend have a Dropbox account, you can, in fact, use it to share files over your Wi-Fi network.

All you need to do is share a folder from Dropbox's web interface. From the My Dropbox view, hit "Share a folder" and choose the one containing the files you want to share. You'll be prompted to invite your friend to view the folder. Once your friend accepts the email request, the folder will show up in his or her Dropbox and they'll start to download the files. If you're on the same Wi-Fi network, Dropbox will transfer the folder over Wi-Fi instead of the internet, thus speeding up the process.

Note that each computer also needs internet access for this to work, so it won't work with the ad-hoc method unless both computers are wired up to the internet, or if one computer is wired up and sharing the internet over the ad-hoc connection. It's generally most useful for the first method we mentioned, when you're both on the same secure local network.

We still don't know if this is the most useful method for everyone (after all, it only works if you friend also has a Dropbox account), but if the conditions are right, it's probably the method that requires the least set-up—just create a shared folder, drop the files in, and go. Hit the link to read more about how it works. Thanks to everyone that brought this up in the comments on our initial post.
