fobs,
My D-Link gear is good for only 22mbps - I did this on a budget!! It only cost me OZ$220.00 (but a lot of my spare time.)
I reliably get that speed over a reasonable distance, but I haven't tried a range vs speed check yet - maybe tomorrow.
As a test of system performance, I put a DVD in each computer in turn and then played it from the other over the link. That worked ok - each played as if it was being run on a local drive.
Then I played them simultaneously (each from the other computer!) That worked too, but both were a bit choppy with vid jerkiness and sound dropouts.
Some numbers you might be able to offer an opinion on ...
Movie A by itself (Eagles in concert, colour, stereo sound) - upload 10600kbps, download 105kbps, total bandwidth 10700kbps or 10.7mbps
Movie B by itself, played in the other direction on the link - (old B+W relic, mono and mono) - upload 6000kbps, download 65kbps, total bandwidth 6065 kbps, or about 6.1mbps
If one were to play the movies simultaneously, each from the other computer over the link, it would be reasonable to expect a bandwidth requirement equal to the sum of the totals, wouldn't it? ie about 16.8mbps, well within the 22mbps capacity of the equipment.
When I played them that way the up and down channels were the same, as you'd expect, but only about 6mbps each, for a total bandwidth of 12mbps - significantly less than I had expected and well under the link's maximum. Both movies were choppy.
Any ideas why that might be? ie, why the unexpectedly reduced data throughput (which, one assumes, would cause the choppiness)?
(I'm not going to lose too much sleep over this - it's a weird configuration that one wouldn't normally use, but now I'm curious! )
Cheers
AA
