Trying to get the Linksys wpc54g-v2 wireless card that Stan has leant me to work on my IBM Thinkpad T23.
This is not going very smoothly so far - if I buy a card I think I should go for a Dell Truemobile 1150, which is reported to work out of the box (http://www.physics.wustl.edu/~alford/thinkpad/T23_FC2.html).
There are two issues:
make rpm target so this is
pretty clean (and can be easily reverted). I first tried the latest
version (0.11) but although it compiled OK, I couldn't get
modprobe ndiswrapper to work (some undefined usb
symbols). Following advice on the web, I then tried the previous
version (0.10), which seems to work perfectly.
Orinoco gold that Alfonso has lent me. This one works perfectly. I had to install the madwifi kernel module.
Doesn't really fit on this page but never mind. Today (17 Nov 2004) the cable guys came and installed my Telecable “broadband” connection. They plugged the cablemodem into Stan's Linksys switch and it works fine. Not so fast though. In theory it should be 600Kb/s (or 600KB/s according to them!). In practice I was getting 8.1KB/s, or ~64Kb/s, for an upload to deimos and only 4.8KB/s for a download.
Here is what I get from tcptraceroute and traceroute

Bizarrely, we seem to go by a much more direct root on port 80 (http)
than on the other ports. traceroute uses some supposedly unused
port, which comes out pretty much the same as tcptraceroute on port
22 (ssh). This is repeatable.
Speed with scp is not much better at 7am - I get 11.5KB/s for download. I get virtually the same with wget via http. Running two downloads at once doesn't improve the total bandwidth much - each runs at just over half the speed: 4.9 and 10.13.
