Recently, we reported on AT&T's push to make it easier for iPhone & iPod touch users to connect to their Wi-Fi Hot Spots. One of our readers, Jamie Phelps, pointed out on his blog that AT&T's Wi-Fi service is not actually a "secure connection," as is advertised in various places on their website; we had overlooked this, and mistakenly reinforced the company's shaky claim in our post.

This brings to light an important point about wireless networks and security, however. It's really easy (and sadly all too common) to hop on to an available wireless signal in your office, at the hotel, or your favorite coffee spot and not even think twice about logging in to your e-mail or checking your bank balance.

What many users don't realize is even though the server you are connecting to (i.e. your bank's website) may employ several layers of security, the connection between your computer and the wireless access point is very likely to be unsecured. Anyone who is within range of your computer can trivially monitor the traffic being sent between your computer and the access point, allowing them to see what websites you may be visiting or capture details about other services that you may be connected to. This isn't because of some gaping vulnerability or software bug, it's just an inherent part of how wireless networks work.

So, what can you do to protect yourself? Read on for a list of simple steps you can take to ensure that your wireless connection is safe and secure.

Last night Apple released a firmware update for Time Capsule, AirPort Extreme, and AirPort Express Base Station with 802.11n. Here are the fixes:

• Fixes some problems with extending and maintaining connectivity with extended networks
• Fixes an issue with clients that enable 802.11 "Power Save"
• Fixes connectivity issues with some third-party devices
• Fixes an issue when the base station is configured for PPPoE
• Fixes some Back To My Mac issues with connectivity and support for third-party routers

All of those sound like issues that could affect quite a few people -- especially those with (gasp!) "third-party" devices. I've certainly had issues with Back To My Mac using a Netgear router, so we'll see if this helps. In any event, firmware updates are recommended especially if you've had any of the above symptoms.

Now you see it, now you don't -- and now it's back. The very brief tenure of AirPort Extreme Update 2008-003 (it was available on Tuesday for a while, but then withdrawn) has given way to the shining reign of update 004. The update is a 2.2 MB patch recommended for all Intel machines on 10.5.5, resolving "some issues with Airport connections when roaming in large WiFi networks."

Some of the commenters who installed the earlier build didn't experience any obvious ill effects; others reported installation hangs, lockups on reboot or problems connecting to wireless LANs, so your mileage may vary -- with any luck the new build has a steadier grip on stability.

You can download the new update via Software Update or (shortly) from the Apple support downloads page.

Thanks to everyone who sent this in

Back in the day, the white dome Airport Base Station supported Power over Ethernet, which allowed the station to be mounted far away from an outlet (e.g. on a ceiling) powered by just the ethernet data cable, great for preexisting buildings where running power for base stations might be expensive or impossible.

The most recent Airport Extreme Base Stations have lacked this convenient feature, but MacWireless is now offering a PoE kit that works with the 802.11n AEBS. The $59.98 kit contains both an injector that plugs into the outlet and a splitter for the other end that goes to the AEBS, allowing both data and power to be sent over a single Cat5 cable up to 330 ft long. A shorter 200 ft range kit is $39.98.

As we noted when the latest Airport Extreme Base Station firmware shipped, Time Machine now seems to recognize USB hard drives connected to the AEBS as valid backup locations. Was this feature added deliberately? Well, Glenn Fleishman over at TidBITS took the trouble to ask Apple about this and he reports that they told him that this is an unsupported feature (and not much else). This is unsurprising given that Apple never made mention of the feature connected with the firmware update (though it was originally promised before Leopard shipped). Fleishman himself even speculates that it was turned on by accident.

So what's the upshot? Apple is offering no support for using your AEBS this way, and so if you have a problem you're pretty much out of luck as far as they're concerned. Further, considering that there have been reports that the Airport Disk can be unreliable, it's probably not a good idea to depend on an Airport Disk and Time Machine for your only backup.

Today Apple released an AirPort Extreme Update for those Mac users running Mac OS X Tiger (version 10.4). Here's the information that Software Update gives us:

This update is recommended for all Intel-based Macintosh computers running Tiger OS and improves the reliability of AirPort connections.

You can get this update by either opening Software Update (Apple menu > Software Update) or by downloading the installer package from the Apple Support downloads site.

Update 9 pm ET: Our comrade David Chartier from Ars Technica points out that the 7.1.3 firmware itself may not be necessary for the new functionality to work; he says he tested a 7.1 AEBS with a machine running Time Capsule & Airport 1.0, and Time Machine was able to see the remote disk. Other readers have reminded us that the disk must be formatted as HFS+ with journaling, and you may have to mount it in the Finder before Time Machine sees it. The freeware TimeMachineScheduler is disabled by this update, comments note.

Update 6:45 am Thursday: More comments point out that if you take a locally-connected Time Machine drive and attach it to an AEBS, you will be starting over with new backups (because the remote backups are stored on sparseimages, not as folders). Something to keep in mind if you already have a long backup history -- you might want to use a different drive.

Sometimes the fixes are subtle and quiet. Once TUAW reader Peder downloaded today's Airport updates and ran the utility, he noticed a new version of the Airport Extreme firmware queued up and ready (v7.3.1). When he installed and rebooted his AEBS -- which happened to have a USB hard drive hanging off of it... well, let him tell you:

After downloading the latest Airport-update I checked for updates for my AirPort Extreme. After upgrading to version 7.3.1, Time Machine recognised the attached USB-drive.

If this is a reproducible result -- this means you, everyone, go ahead and start testing this firmware! -- that means that the now-you-see-it, now-you-don't Time Machine to AirDisk feature of Leopard has finally arrived. Sure, the Time Capsule is a one-piece solution and quite economical, but for all the AEBS owners out there who have been waiting patiently, this would be a very nice bit of March madness indeed. [Response to "just-a-guy" below: Remember, this is the Airport EXTREME only; the Express doesn't support AirDisk at all.]

Seeing the same results as Peder? By all means let us know. He was kind enough to send us a few screenshots, see below.

Got a shiny new AirPort Extreme base station, speeding those bits around the ether? Today Apple released new firmware for the fast-but-flat access point, version 7.2.1, downloadable directly or via the AirPort Utility. You'll need version 5.1 or better of the AirPort Utility to install the patch (you can get 5.2.1 via the Base Station Update 2007-002).

In addition to the usual bug fixes and security updates, this patch is WiFi certified for 802.11n draft 2.0. This certification may help when integrating the AE with third-party devices. Then again, it may not...

After all the trouble they had with their Airport Extreme, ComputerWiz did exactly what any sane person would do with a computer they didn't understand, and took it apart. No? That's not what you would do? It's what I would do.

Anyway, the main goal was to find out if the new Airport's Gigabit speeds could have just been accomplished by upgrading the firmware of the old Airport Extreme, so CW ripped them both apart and took lots of pictures. All the watermarks make it a little hard to see, but what's clear is that the two different Airports use two different chips-- the earlier one uses the Broadcom BCM 5325, while the latest, Gigabit-speed Airport Extreme uses a BCM5395 chip.

What does this mean to you, as an Airport Extreme user? Not much. But it does mean that the Airport update is firmly hardware based-- you can't, for example, use an expander or a software update to speed up your old Airport Extreme unit. On the other hand, thanks to CW, you can get a look at the innards of both units, without having to take them apart yourself and that's always fun.

Do you have an AirPort Base Station? Do you enjoy applying updates? Well then, buster, today is your lucky day. Apple has just released an update by the name AirPort Base Station Update 2007-002 for Mac. You'll need any flavor of OS X 10.4 to get this update, as well as an AirPort Extreme or Express. This update, 'includes general fixes and compatibility updates for the following applications: AirPort Utility, AirPort Disk Utility, AirPort Base Station Agent.'

I know our very own David Chartier has encountered many issues with AirPort Disk, so here's hoping this update fixes it.

Along with all the other updates in the Apple Store on Tuesday, Airport Extreme got a nice one-- according to the specs on the page, they're now offering Gigabit ethernet speeds. Or are they? ComputerWiz went out and grabbed two of them right away, but no matter what he tried to do, he couldn't get the base station to move past 100Mb speeds.

There could be a number of things happening here-- I don't have the knowhow to judge whether they did everything they could or not, but the attempt seems reasonable to me, and if you have to mess with settings that much on an Apple product, something is wrong. They also say that Apple had to go into the back room to get the Airport Extreme, so it's conceivable that they grabbed the wrong one-- except that CW claims the box itself said Gigabit.

So something is screwy here-- is it possible that Apple shipped Gigabit Airport Extremes that weren't actually Gigabit?

Update: Looks like it was just a faulty unit, as CW updated, and apparently the second unit worked fine. Anyone else having problems with theirs?

Thanks, David!

Apple has quietly updated one more product today. Hidden at the end of the iMac press release we find out that the Airport Extreme Base Station now sports Gigabit Ethernet ports (one WAN, 3 for devices) whereas only yesterday they were 100baseT. The Airport Extreme Base Station tech specs haven't been updated on its own site as of yet, but the picture above was snagged from the Apple Store. They are still priced at $179.

Thanks, Stephen Chan.

Last week many, many of you reported problems with wifi since the OS X 10.4.10 update. Fortunately, Apple appears to have heard your cries of anguish and has released the Airport Extreme Update 2007-4. Apple doesn't say much about what the update contains but does say it "is recommended for all Intel-based MacBook, MacBook Pro, and Mac mini computers and improves the reliability of AirPort connections."

So, for those of you who had problems, did this fix it?

Thanks, Kender!

If you've got an Airport Extreme Basestation and haven't yet downloaded Firmware 7.1, this is your chance to do that and more. Today, Apple has released Firmware 7.1.1 for the Extreme Basestation with 802.11n. This includes all the fixes from 7.1, plus improved support for:

• Printers and Routers, VPN, PPPoE, WDS(ACL), WEP(TSN)
• Localized file naming, port mapping, IPv6, and NAS
• Improved stability with keychain passwords
• Improved support for third party applications saving files to a USB disk
• Improved support for AirPort USB disk stability and power saving, disk read/write performance, disk file sharing and passwords
• Addressed an issue where Base Station would not request a password when expected

Get it while it's hot (though we're guessing this won't be the only "new" release from Apple today).

In today's New York Times, friend to Mac users and finder of lost loves, David Pogue does a nice user-focused job of reviewing four 802.11n wireless routers (story, video), evaluating performance and ease of setup for the Apple, Belkin, Netgear & Linksys offerings. His conclusion: the Airport Extreme, while slightly more expensive than the other units and lacking Gigabit support on the Ethernet side, is far and away the best performer (up to 90mbit transfer speeds, almost double the best results with the other three routers, testing details in his video) and certainly the easiest to configure and control. He also points out that current Macs are firmware-updatable to 802.11n, while most other PC manufacturers will make you buy a new card to get your speedy on.

For the real entertainment, however, check out Pogue's behind-the-story blog post. His experience with the Netgear software installation for a USB 802.11n adapter -- a madness-inducing swirl of EULAs, unsigned drivers, UI design from Graphix-R-Us, and plain ol' Windows user-hostile behavior -- is both familiar and chuckle-worthy.

Update: Clarified the 2nd paragraph to note that Pogue's issues with the Netgear installation were specific to the adapter, not the router itself.
