If you wanted to connect to two different networks you could use this. So say you had an internal network which you had your own computers all linked to but were not connected to the internet, you could use one port to connect to this network. Then you could connect the other port to a broadband router/modem and access the internet on your Mac Pro. It's ...

Apple Remote Desktop will involve either having a VPN or open ports and static IPs. I think you will be much better off with LogMeIn.com's free version, which will require zero intraction from your family members and open ports are not necessary. You will need to know a user's credentials on their computer. If they require more privacy they can disable ...

Your External IP Address (or, as you call it, the IP address reported by whatismyip.com) is not under your control and you can't simply set it to static. Your ISP gives you a new one when you reconnect, although there are chances that you might get the same, you should never count on it. In order to solve this problem you have two choices: Some Internet ...

If you only need throttling for Web development, I can wholeheartedly recommend Charles. It's an excellent tool for debugging HTTP applications anyway, and among its many features, it's got a Throttle option. The software isn't cheap, but it does an excellent job.

If your iOS device is on version 5.0 or higher, then yes, you can do it directly from the handset by going to Settings/General/Software Update. If you're on iOS 4.x then no, you will need a computer to do this. To upgrade in your situation, I would recommend the following steps: 1) On your new laptop, open iTunes, and in the preferences on the devices tab, ...

This is going to be a starting point answer, hopefully you can find something strange while comparing the shots and fix the problem. If you can connect to Skype that means you have connectivity, but your computer is unable to perform name resolution (that is, convert the address of a service -like a webpage- to an ip address). Skype may work because it ...

In agreement with the original poster, in this answer I put together the comments above that describe the troubleshooting steps that helped solve the issue. Realize that PeerGuardian uses a KEXT. As strangelydim commented, PeerGuardian (an open source privacy oriented firewall software) uses a kernel extension (KEXT). The KEXT is used to block connections ...

Not that I know of however you could try turning internet sharing on on your computer. This will create a wireless network that you can use on your iPod Touch. This is easy to do if you are using a Mac. Assuming that internet comes in over Ethernet, go to the Sharing tab in the System Preferences application. Click the internet sharing tick box and ...

If you are certain that your Wi-Fi connection works fine when you are somewhere else, there might be signal or compatibility problems between your router and your Macbook Pro. Contrary to popular belief, wi-fi connections are not a voodoo thing, and they just involve radio waves, just like a cellphone and any other wireless device. Reasons for a Wi-Fi ...

Try using iStumbler to detect and identify neighboring and overlapping wireless access points (WAPs). It's likely an interference issue that can be solved with vigilance. You need to find out what channels your neighbor's WAPs are using, and then switch your router to use the least crowded channel you can find. Ideally you want to use channels 1, 6, or ...

When your connections starts timing out, can you do arp -an in Terminal.app and see if you still have all MAC addresses in the ARP table? as in - your router's MAC address, or the host you're trying to ping? If you do (and you have the time before it starts working again), can you flush the arp table (sudo arp -ad) and then see if your router's MAC address ...

Any application can network directly or use the system settings. As @geekosaur states, Opera has its own setting, as does Firefox (along with the option to use the system settings). Chrome and Safar use the system settings. It's really up to the application developer how they implement their proxy controls (if they even have proxying!).

This is currently a known issue that lots of Lion users are reporting. The average seems to be 2 wifi dropouts per hour. The current work around is (as you discovered) to toggle AirPort on/off. This particular issue seems to be getting alot of attention so I'd expect a fix soon. Apple support forum topic about this issue

A simple lamp timer on your modem, router or access point device would be a low tech solution for a given fixed location. No scripting expertise required. Put tamper-proof tape on the jacks and plugs if you want to check for cheating. If you only want to affect one iMac, put a separate router on its ethernet cable, and plug that into the lamp timer.

Don't overlook "the parent app". It turns on the logging of safari using parental controls. Sets the normal time limits when the mac can be on and off. Then it communicates to the children "the rules" and what happens when the parent determines that they have been broken. Why spend money or time on a more controlling solution if you can ensure they don't ...

With regard to modifying the system AirPort icon, I do not believe that what you are asking for is possible. To show internet connectivity, I use a combination of WiFi Signal (which could be substituted for the OS X AirPort menu bar item) and Cloud: AirPort off AirPort on & not connected AirPort connected & no internet AirPort connected ...
