Long-Time reader, first time caller, Tim.
Take away the anti-Apple editorial comments, please...
The Apple Airport Extreme 5th is a fair performing 3*3 stream dual-band router at a premium price. The real question is... is it worth the slight premium over the others?
Truth be told, Apple has traded off features for stability and performance.
Yes, it doesn't have all the bells and whistles that Netgear, D-Link, Buffalo, and Cisco-Linksys offer, not having an internal web-server could be considered a plus... what I like about the Airport series (AP Extreme, AP Express, Time Capsule) is their stability and performance - they're no easier or more difficult to setup than any other router, but the stability is the key point in my purchase decision... it's nice not having to reboot the router every week "just because" - my old Linksys WRT-610N was just as fast for two stream clients, but the stability issues there...
Some recommended corrections on the review:
1) Guest Network is provided for both bands, the review mentions 2.4 GHz only
2) Port Forwarding - static as well as dynamic through NAT-PMP (similar to uPNP)
3) 5GHz can be named separate, with the following caveat, the Guest Network will have the same name in both bands (e.g. Airport, Airport 5GHz, but the Airport Guest has to use the same for both bands)
4) IPv6 - fully supported, but agree with the review, it's a bit arcane, but if you set up a tunnel, it works, not just for Macs, but for all platforms.
Comments:
Lack of WEP is not a bad thing - time to say goodbye to WEP, it's not much better than running an open network, and the performance hit to 802.11n is yet another reason... if you're stilll running STA's that absolutely need WEP, then the Airport series is likely not the best AP for you...
The lack of Wide Channels in 2.4Ghz, I believe, is a plus - less interference for other wireless devices that share the same frequency band - bluetooth is a good example, but also having wide channels in 2.4Ghz is challenging enough in a mid-to-high noise environment. One thing about wide channels is yes, one could get possible better bit rates at the physical layer (MCS), but you're sacrificing error correction and coding gain. If you're in a low-noise environment, it's not a big deal, but in a residential neighborhood, or better yet, in an apartment complex, where the neighbor's AP's are also running, likely either in the primary or secondary channels, you will lose performance at the network layer (TCP/IP and UDP). MCS is not everything, you really have to look at packets...
The routing performance - not related to the WiFi chipsets 5th Gen, but to the firmware, and earlier AP Extreme N users also benefit from this.
WPS - is supported - you have to read the manual... in a nutshell...
1) select the basestation in Airport Utility
2) Click on Manual Setup
3) Go to the Base Station Menu on the menubar
4) Select "Add Wireless Client..."
WPS is a mess... Apple is no better than anybody else - sad to see this state of affairs... lucky for most that WPS is more marketing than real world...
Getting back to the 2.4Ghz Wide Channels - note that all current Apple STA's set the 40MHz-Intolerant bit in 2.4Ghz - it would be an interesting test for all AP vendors to see if they honor this flag...
Now some asks...
1) Disk Performance - not just for the AP Extreme, but for any SOHO router/ap, this is going to be a big deal for some...
2) WDS (or proprietary network extensions) - if supported, would be interesting to see the setup and performance on the extended network.
