Unplug it, wait a moment, plug it back in and it should be back to factory defaults. If you get into a problem like that, stick a paperclip into the bottom of the device and hold it there for about 10 seconds. It’s also easy to set it up such that you can’t configure it (like if you try to make it join a wireless network but don’t properly get a DHCP from the Ethernet plug). Much too often, I got an error when “reading configuration from AirPort Express”. Press the Button With a Paperclip to Reset the AirPort Express So if you’re testing this kind of thing, unplug the Ethernet cable from the computer. By default, Mac OS X and Firefox tries to get Internet from the Ethernet port and if it can’t get it from there it fails, instead of trying on the wireless network. The problem is that I didn’t ever disconnect the Ethernet cable from my computer. When I was testing the AirPort Express by plugging the Ethernet from my cable modem into it, then connecting wirelessly from my desktop, I wasn’t able to get Internet. On Mac OS X, Ethernet takes Priority For Internet Operations Thus, be sure to install 6.0, update the firmware, then install 5.6. Apple unfortunately stripped out a lot of features, like profile management, from 6.0. However, you still have to install the latest version (6.0 at the time of writing) to get the proper firmware, THEN install the old version (5.6) to get access to the advanced features. The first kicker is that the most recent version of the AirPort Utility does not have the same functionality as a former version, so if you know a little bit about networking, installing the new version is a bit of a waste – you can’t do things like manage different profiles, which are useful if you want to have a profile for “Playing Music At Home” and “Internet Sharing On The Road”. Let me write a post explaining how to not waste time configuring an AirPort Express. I’ve wasted a bunch of time today trying to configure the Airport Express. Even now, my 802.11n wireless network seems to not really work well – it has a weak signal and any device seems to have a random chance of not connecting to it. Lots of networking stuff, from cards to wireless routers and stuff. Thus far, I’ve had a lot of random failures, like my 4-year old PowerMac G5 that one day suddenly failed to power on, a brand new external hard drive, bad RAM in an old computer, mice (lots of mice) and assorted networking equipment. Back in Waterloo, I was rumoured to have inherited a “curse” about hardware from a fellow graduate student (hello, Ben!) – the curse was that hardware would randomly fail inexplicably in your hands and that you’d spend many hours trying all kinds of configurations to no avail. Yet, for some reason, networking equipment and I simply do NOT get along. So really, it seemed like a win all around. Since I just moved, my computer is no longer able to connect to the speakers in the living room since it’s too far away. An added bonus is that it also had a 3.5mm stereo headphone jack/mini-TOSLink jack that would enable me to plug a set of powered speakers into. Second, it allows you to share an Internet connection over wireless, which effectively means that I can connect the Ethernet to it and then share the connection to my MacBook Air. First, it’s small enough to carry around with me on a trip. This would be a great way to solve my above problems. Lately, this problem has been compounded because I have a Macbook Air, but no Ethernet adapter.īecause I’m traveling again this weekend, I decided that I would purchase an Apple AirPort Express. Internet sharing on the Mac has never seemed to work quite the way I wanted it to. This was a bit of a nuisance when sharing rooms with people, or if I’m interested in trying to check something on my iPad. I travel somewhat frequently and often encounter hotels that provide a cable and no wireless connection.
