[I ask this here, in the CF forum, since there is perhaps enough different about CF (e.g. wireless drivers) to make it CF specific]
I'm getting very poor transfer rates when copying files over wireless, e.g. less than 1Mbit/sec, even though the wireless connection rate is allegedly 100 times that.
I'm using an Edimax EW-7711UAn dongle (at 2.4GHz), which works perfectly, functionally at least. But I struggle to get more than 1Mbit/sec when copying files to/from the PC.
On the Humax, cmdline iwconfig reports between 40--135 Mbits/sec for the connection rate, and my wireless router confirms those figures (which fluctuate). I don't expect to get near that in practice, of course, for real file transfer, given the usual overheads, but I might expect to get near half that, perhaps?
Initially, I was using rsync over SSH (with SSH compression disabled), but thought perhaps that ssh was too much for the Humax cpu. But a wget of a file from my PC, over plain HTTP, fared no better, still around 1Mbits/sec (although perhaps slightly better than rsync/SSH).
So, should I be surprised?
The Humax isn't all that accessible, so I can't easily move it nearer the router to see if there's a massive improvement. But if the Humax, and the router, are reporting connection rates in the many tens of Mbits/sec, shouldn't I hope for better than 1Mbits/sec for real transfers?
Anything obvious I should test (other than the above, which I will try to arrange)?
thanks much indeed.
