The range is pretty bad relative to my previous unit (WAP54g).
I replaced the antennas with higher gain ones but the reception didn't get better probably worse. Finding dual-band SMA antennas is not easy as most of the antennas out there on the commodity market are single band only.
Could even be antenna positioning issues on the N band but it is driving me nuts trying to figure out why it doesn't work well.
The N band support is so aggravatingly bad I don't connect to it, you can't stream from it (at least in my house) and decent throughput happens if I'm standing over top of the unit.
I could probably move it a bit and see about better range but given I had better luck with an older device attached with the _same_ screw mounts on the wall doesn't let me to believe much other than it's not a great device.
The G band support is fine so maybe the unit isn't the issue but radio properties of N band devices in my house.

But does it have removable antennas a la WRT-54G? Do you know of any (other?) N devices to which you can attach external antennas (i.e. unidirectional, specifically)?

Further to my comments at the last meeting, I was pleasantly surprised
when I bought a D-Link DIR-825 and discovered it can run DD-WRT.
This is a *simultaneous* dual-band (i.e. two radios, one at 2.4GHz, one at
5GHz) 802.11N router with 5 GigE ports, a USB port, two antennas, and the
usual array of activity lights on the front.
There is a beta build of DD-WRT that runs on this unit (and thus
presumably OpenWRT will also support it soon if not already).
Range & performance are OK but not great.
The price, however, is impressive: you can typically find it online (in
Canada) for under $150. If it were a $250 unit, it would be utterly
unremarkable (aside from being one of the first dual-radio models to run
DD-WRT) but considering that you can still regularly find 802.11G and
single-band 802.11N routers for over $150, that makes it impressive - for
now.
With the stock D-Link firmware, the USB port can be used for (apparently)
*any* device whatsoever, and includes software to remotely connect a
Windows PC to the port. Not sure how they've done this, but I'm told it
should work for any USB device (subject to bandwidth limitations, of course
- USB2.0 is still faster than 802.11N).
DD-WRT can expose USB storage devices and (I think) printers; so you do
lose something compared to the factory firmware. Flashing DD-WRT onto the
device requires TFTP while putting the device into disaster-recovery mode;
it was harder to find the instructions online than to actually do it.
