Hi.
Does any one know how fast the Wi-Fi connection on the N800 is?
I have a D-Link DWL-2100AP 108Mbps access point.
I am guessing that the N800 has a 54Mbps type Wi-Fi because of
power consumption constraints.
Am I right?

It has 802.11g, which would theoretically give you 54 Mbps.

In the real world, you will never see anything approaching those speeds. 20ish Mbps is pretty much it for g. N might get you closer to 40Mbps. Maybe. If you don't have any bluetooth devices, cordless phones, or microwave ovens nearby or you are running a 5ghz N network (which you aren't), you might get upwards of 60 or 70.

Add more than one wireless device and it'll get even worse.

If you are wanting to transfer big files without waiting around forever, I highly suggest either using the USB cable or putting the SD cards in a card reader. I don't know what throughput the n800 is capable of, but I can't imagine it's all that great.

just a guess but the wifi is faster than the max writespeed of these sd cards?

Class 2 SD cards can write at a minimum of 16 Mbit/s (2MB/s).
Class 4 SD cards can write at a minimum of 32 Mbit/s (4MB/s).
Class 6 SD cards can write at a minimum of 48 Mbit/s (6MB/s).

Most decent cards significantly exceed that ability, and are often advertised as being able to write at 160mbit/s (20MB/s).

So, while it's possible that an SD card could be slower than a wifi connection, it's unlikely, given that you have a remotely decent SD card.

Yeah, I thought as much. I do use USB to move data to and from the N800.
Thanks for the info.

If you use a decent N accesspoint with three antennas (N uses multipath to it's advantage, instead of getting interfered with by it), you can easily get 100-120 mbit at 2.4ghz.

I have never seen my N810 transfer files faster than 700KB/s (8mbps) on the local network. This is with WRT54 access point, G mode.
