You may remember a post I wrote a while back about the Pentagon’s plan to get mobile devices working on military networks, and how we were able to ascertain that yes, they were working on testing iPhones and iPads and no, they were not planning on jettisoning support for Blackberry devices.
According to Spencer Ackerman at Wired today, iPads will finally have passed the rigorous security review set out by the US [Read More...]
Nmap is a powerful command line network discovery utility that lets you review network inventory, host response and uptime, and perform security auditing through port scans, OS and firewall detection, and more. Though it’s free (and open source) and ships along with many versions of linux, it doesn’t come standard with OS X installations, and thus must be installed separately. Nmap is generally fairly advanced, but it [Read More...]
Retrieving a list of preferred wireless networks can be helpful when troubleshooting wi-fi problems. The following trick will do just that, and it’s similar to a tip we covered recently which showed how to see a list of previously connected wi-fi networks using either System Preferences or a lengthy command line string, but as far as the command line goes the following command is much shorter and cleaner, and doesn’t require the use of sed and regex to clean up [Read More...]
Knowing which wireless networks a Mac has been connected to in the past be can be helpful for a variety of reasons, including network troubleshooting, determining where a Mac has been, if a specific wifi password is recoverable, and a myriad of other technical reasons. Searching for past networks is completely different from finding currently available networks, and you won’t recover historical data from the menu bar item or otherwise excellent OS [Read More...]
Apple exerts more control over cellular networks than any other technology company on the planet. If a carrier wants to sell the iPhone they have to pay Apple a heft subsidy. Before getting the iPhone 5 to run on their LTE network, Apple has to come around and make sure it doesn’t suck before they enable LTE on the iPhone or iPad.
The reason behind Apple testing carrier’s networks before enabling 4G [Read More...]
We already know that the iPhone 5 will support faster 4G LTE networking, but details surrounding international availability have remained scarce. While it’s assumed that the iPhone 5 will support LTE speeds on U.S. carriers like AT&T and Verizon, accessing LTE on carriers in other continents is a whole other issue.
According to a new report from The Wall Street Journal, the next iPhone will indeed support LTE on certain networks in [Read More...]
Open Wi-Fi networks are everywhere, if you’re stationed in an area with tons of them you’ll probably want to prioritize your own network to be the top wireless network to join so you don’t accidentally end up on someone elses unsecured network. Prioritizing is also a good idea if you use Personal Hotspot in public so you don’t end up on an open public access point. [Read More...]
A long hidden airport command line utility buried deep in Mac OS X can be used to scan for and find available wireless networks To do this, the first thing you’ll want to do is create a symbolic link from the airport utility to /usr/sbin for easy access. Launch the Terminal and type the following command: sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport The [Read More...]
I recently encountered a strange issue where Mac OS X Lion stopped remembering a specific wireless network, forcing me to manually select the connection and then enter the password each time I wish to connect to that wireless router. This appears to be a common enough issue with wireless connectivity in OS X Lion and it usually occurs when waking from sleep or rebooting a Mac, [Read More...]
Wi-Fi Diagnostics is an incredibly useful utility to troubleshoot and optimize any wireless network and the signal strength of computers that are connecting to it. This utility comes bundled in Mac OS X Lion and works with all wireless routers and not only the Apple branded ones, meaning you can improve the performance of just about any wifi network by using it and making some adjustments along the way. It’s easy [Read More...]
