Does original iPad support 5ghz wireless N?

nvm

Yes, it does. I've been running 5GHz only 'n' for a few years now. Both iPads support it. FWIW, first-gen AppleTV is also running 5GHz. I'm running a new-style (square) Airport Extreme (built-in hub).

I believe the iPhone 4 does, but I don't have first hand experience with that one.
Edit: I stand corrected - the iPhone is 2.4GHz 'n'.

I have several devices that are 'g' only, so I run those off an older gen Airport Extreme.

I just wanted to agree with and confirm the above. I have a 5GHz N network, and the iPad 1 works on it fine.

True. The iPad does support 5GHz 802.11n
The iPhone 4 doesn't, only 802.11n 2.4 GHz only.

You can goto Apple website to see more details

The iPhone only supports 2.4Ghz WiFi N (as stated on the iPhone tech specs page)

The iPad 1 supports both 2.4Ghz and 5Ghz WiFi N. You can see the tech specs on the Wayback machine where it makes no mention of 2.4Ghz only. I've also used my iPad without problem on a 5Ghz router

For the iPad, check the Product Information Guide for the SAR specs for a list of all the wifi 5GHz band frequencies used.

Cool, thanks!

So, given then iPhone doesn't support 5ghz will using N in 2.4ghz for the iPhone reduce interference or am I right in thinking the problem will remain that it will get interference from all the G networks around me?

Any recommendation as to a good dual mode Adsl router/modem? The extreme seems a little overkill (and over priced) for a simple home network!

About the only thing you can do [for 2.4GHz band] is try and set the base station to an unused channel, rather than leaving it automatic. For instance, if you find other network's using the upper channels, then move yours to one of the lower ones.

If you have any wireless land-line phones on 2.4GHz band, I strongly recommend buying a 5.8GHz model. The lower band models will definitely cause grief.

A dual-mode (if you mean dual-band) doesn't necessarily mean simultaneous use of both bands. The current Airport Extreme does (and, I imagine there are 3rd party ones too). Also, the Airport Extreme doesn't include an ADSL modem. If you go that route, you can disable wifi in the modem (and routing), then use the Extreme both as a router and WiFi base station. If, you need to keep the routing functionality in your modem, then you can setup the Extreme in bridged mode.
