| Since I rebuild my laptop, I'm having problems with my wireless LAN card.

| It's a Lucent Orinoco Silver card, which supports (only) 64-bit
| encryption, and it talks to a D-Link DWL-900AP+ access point.
|
| Before the hard disk in my machine blew, I was running Debian 3.0 with
| the 2.4.18 kernel and all was good. Now though, I've got Gentoo
| installed with the 2.4.22 kernel from sys-kernel/gentoo-test-sources and
| the card only works properly if WEP encryption is disabled (not good).
|
| Pulling data down through the card seems fine, as in I can download
| large files from other machines on the wired LAN at decent speed, but
| when I'm sending data, the connection freezes after a few KB's (like
| four or five KB).
|
| This has effects like...... SSH works with version 1 of the SSH
| protocol, but not with version 2 because more data is exchanged. Web
| pages with long URLs fail, like search engine requests or slashdot
| posts. I can't send emails longer than a few lines.
|
| Everything works OK with the encryption turned off though :-/
|
| I need the 2.4.22 kernel in order to support my scanner though.
|
| I'm using pcmcia-cs card drivers, not the kernel ones. Version 3.2.4 is
| installed.
|
| Anybody got any ideas?

More info...

If I flood-ping a host on the wired part of the LAN, there seems to be a
threshold packet size, above which all the packets get dropped (using
the -s parameter). This threshold changes when I change the MTU for the
interface with ifconfig. At the default of 1500, the maximum packet size
is about 550 bytes.

Maybe a firmware upgrade is in order here? The encryption is handled in
the card, isn't it?
