http://mandrakeexpert.com/showarchive.php?arc=57799 Apparently, the alcatel.sys file (normally used in windoze) can be copied to /usr/share/speedtouch/mgmt.o (which is highly surprising, since the format of a .sys file and a .o file are very different, but anyway ...). After installing mgmt.o, you might try using the guide again (lynch's instructions) and see if things improve. Also, what is the specific model of your modem and what is the interface (USB, internal PC card, etc.)?
Any info appreciated. Hope this helps.
