    Very few consumer items are 802.11a anymore, It has 802.11n so whats the big deal?

    Yup, I was disappointed when I found out, just a marketing gimmick really, specially since my iPad has the 5ghz chip.

    Is this real life?

    802.11n is 2.4 and 5GHz, the iPhone 4 only supports 2.4

    Yes, its even written this way on the spec sheet. It really sucks. I still connect my phone to my G router because I don't want to set my N to 2.4 Ghz.

    I almost cried when I found out. Microsoft did the same thing with the new Xbox. It has n built-in but it only supports 2.4, while the external adapter supports 5. I hate it.

    Ummm the 802.11n standard supports 5.8, the hardware AP or router, does not HAVE to support it. savvy? Besides read up my friend the 5.8 does not have have the performance increase the 2.4 does.

    Well now I don't even know why I got one if only my MBP can utilize it.

    FFFFFFFFFUUUUU-

    My launch 360 red-ringed two weeks after I got it, before RROD even had a name. Then it failed again two weeks before Halo 3 came out, so I sent it in and bought an Xbox 360 Elite to play (nerdy I know).

    Then about five days ago I was streaming Netflix on my Elite when it failed on me too. So I was thinking of getting the new 'S' console....:(

    ......wut? Yes the device doesn't have to support it, but why it doesn't is my question. And the 5Ghz band is a great increase because I live in a multi level building and there are literally about 12 SSIDs I pick up...along with other devices. It's crammed as **** around here...and what is 5.8?

    5.8Ghz is the frequency you are so fond of. If 5.8 becomes as popular as 2.4 you will have 12 or more visible ssid's in that range too. And eveytime someone picks up thier coredless phone (most are 5.8 these days) your bandwidth will go to hell.... so good luck with that freq.

    Actually, most newer cordless phones are DECT 6.0. These operate on a dedicated 1.9ghz frequency that is not shared with other devices.

    True, but how many households have switched. not many. I am sure you will find more 5.8 phones than 1.9.... maybe in 5 years that will be different.

    your nuts.. I work for a Large Wireless integration Company. We have done several large scale Citywide wireless systems for the public safety sector.

    We use a MESH system that allows you to connect multiple AP's wirelessly together to make the network. ALL of the devices connect to each other on the 5GHz freq for their backhaul Specifically because of the performance gains.

    2.4 is too congested and unless the government gets some more spectrum freed up, 5.8 is the future.

    5.8 has less range than 2.4. Simple physics. 5.8 may be the future, but it requires much more power than 2.4. Performance gains are very slight because the ISP is the bottleneck, not the frequency. Until the connection you get from your ISP gets faster, 5.8 vs 2.4 offers little to no performance gain.

    Umm ok, so do I, and why are you not using 4.9 if it is for public saftey? That is the freq you should be using and any reputable "MESH" manufacturer supports 4.9, like Firetide for instance. Besdies I was refering to 5.8's use in the consumer market not municiple, backhaul, ptp ptmp or mptmp marketplace. Be careful who you call nuts... lol

    I dont want to get too far off topic, But Motorola's MotoMESH uses 5.8GHz as the wireless link between AP's. Not 4.9. and there are several Cities using them that we have designed and installed.

    That does not make it a good idea... I would not put "public safety" over a public freq. This is asking for trouble.

    In my house, the G network at 2.4 is for lower-speed requirements, such as laptops and phones. I have a second N network at 5 GHz for HD purposes only, mainly between HD-DVRs.

    Most of the benefics of 'n' you get it from using the 5GHz, at the 2.4GHis pretty much better to use G

    Thats not true. Better read up before you post again. There are 40 Mhz channels in both freqs.

    First at all, It is true, second. I didn't say "more channels" i said more benefices, you better read up before correcting other people

    Its probably too much of a pain to add 5ghz because of the external wifi antenna. Maybe they didn't think the extra effort was worth it.

    Adding 5Ghz would mean adding another antenna. The way things are designed right now, there's no room.

    Dual band Airport Extreme, all my comps are on the 5 GHz wireless channel and average about 25 Mb/s download speeds, we also have two iPhones on the 2.4 GHz wireless channel that average 15 Mb/s download speeds.

    When I run the comps on the 2.4 Ghz channel down speeds drop to around 15 Mb/s and all comps have been tested on both channels and all experienced the speed drop. So 5 GHz does make a difference.

    Dual band accomodates old and new devices and is the best option IMO.
