Sometimes you get network interference, particularly when two or more networks are on the same channel. In built-up areas (I'm London-based, for example) you find that people in flats near your own are coming online with WiFi networks of their own. Here's the situation: WiFi networks are spreading fast. You can use iStumbler to find free or unsecured WiFi networks to jump onto, but it can also help you boost your own home wireless network. This fantastic free open source tool helps you find wireless networks and devices using an AirPort or Bluetooth equipped Mac. Every Mac user should have a Dropbox account. It is also far more powerful and configurable than iDisk. This is iDisk without the high annual fee. There's even an iPhone/iPad app so you can access your most important research and other documents while you're on the move, and you can create shared folders which allow groups of people to share and collaborate on files. Once installed it enables you to sync what's on your Mac with all your other Macs. I make particular use of it to run Maintenance and Cleaning tasks manually, as this invariably speeds up my system and reclaims drive space.ĭropbox is free and incredibly easy-to-use. I've been using it in its various iterations (it gets updated swiftly subsequent to the release of any new OS X upgrade) for many years. "A multifunction utility for Mac OS X which allows you to verify the Startup Disk and the structure of its System files, to run misc tasks of system maintenance, to configure some hidden parameters of the Finder, Dock, QuickTime, Safari, iTunes, Login window, Spotlight and many Apple's applications, to delete caches, to remove a certain number of files and folders that may become cumbersome and more." There's other solutions for this ( Cocktail, for example), but I use Titanium's Onyx, an essential utility designed to keep your Mac in fantastic shape. Little Snitch runs inconspicuously in the background and can also detect network-related activity that indicates viruses, trojans and other malware. You can then choose to allow benign requests, while forbidding unwanted communication attempts. To stop the "ping" you can always hit ^C, or just exit from terminal.This utility monitors your system and lets you know when applications are attempting to make an outgoing connection. The ping program also gives you some handy information about how healthy your connection is (which was its original purpose). Of course you can ping many other major sites besides Google. Keep this running in the background to keep your connection live. This will send a continuous little "ping" message to Google, which Google politely returns, usually in mere milliseconds. So open a terminal (in spotlight you can type in 'terminal' and choose that application) and in the terminal type something like this: But another solution is to use the very simple "ping" program in a terminal.

If so, that's why iStumbler worked - it kept "pinging" the network, which kept your connection in-use. Unused connections for you when on battery power, to save juice. Think Mac would describe this as a feature rather than a bug - as I understand it, the deal is that wireless connections take battery power, and so they drop As mentioned, dropping wireless connections seems kind of an old problem - I had it on an older Mac, too, until I found the solution. I came across this message since I've also had trouble with iStumbler on 10.6, but meanwhile I have something of a solution to the original problem.
