I have a 10 MBit Ethernet LAN. Connected to it is a Belkin wireless AP.
The Belkin AP and all the other hosts on the LAN connect to a 10 MB
(only) hub. My daughter brought her Pismo (with OS X 10.4) home for the weekend, and her network speeds were terrible.
Investigating, I discovered that if I use a wired Ethernet connection to
the Pismo, everything was fine. Then I noticed that the Airport card had negotiated an 11 MBit link with the Belkin. I suspect that the extra 1 MBit/second is causing all the problems.
A while back, I had some network problems that turned out to be due to Autonegotiating NICs setting up a 100 MBit/second link that the cables couldn't handle. This looks like the same thing, but without the wires.
So the question is, how do I force the wireless connection to be
something less than 10 MBits/second?
thanks, Isaac
Speed mismatches are normal in networking.
My experience is that OS X has broken TCP handling. My suspicion so far
is that it's related to out-of-order packets being handled incorrectly. There's definitely something that keeps it from working well on some
routes that other computers don't have a problem with. Even minor
packet loss causes extreme throughput loss too.
