airport + dhcp

airport + dhcp

[Jean-Jacques Levy]

Did anybody meet speed problems when connecting an airport to a dhcp
cable tv ISP?

The speed is then incredibly slow, inducing timeouts for pop servers
as soon as there are long messages to transfer.

But the speed is quite normal with a real wire connexion between my
powerbook and the cable tv modem (ie without the airport), when I use
the same airport with a fixed IP adress at my office. It seems the
problem happens only when combining airport and dhcp (under linux or
macos9/10).

I run 2.4.15-ben0 kernel on a pbg4.

Thanks for help.

I'm afraid if the problem also happens with MacOS, it's an issue
with the station firmware. You'd rather report it to apple ;)

You also can try running Linux on the base station :-)

Well, in fact, I was wrong. The problem is only for Linux. In
Macos 9, it works perfectly. How to debug this? I did tcpdump.
I got msgs crossing each other missing ack's...
