Hi, I have two laptops and a 3com 3crpag175 cardbus. In one of the two laptops the cardbus works great. I get following output: I tried it also with the other laptop (with the same linux kernel) and it seems that the card has network problems. I can only do the following: modprobe ath_pci : the drivers 'sees' the cardbus with no problems (the led of my wireless cardbus begins to blink. iwlist ap : shows the accesspoints correctly and I can't make a decent network connection: I get the following output when 'ifup ath0': ---- sit0: unknown hardware address type 776 sit0: unknown hardware address type 776 Listening on LPF/ath0/00:0d:54:98:ad:00 Sending on LPF/ath0/00:0d:54:98:ad:00 Sending on Socket/fallback/fallback-net DHCPREQUEST on ath0 to 255.255.255.255 port 67 DHCPREQUEST on ath0 to 255.255.255.255 port 67 DHCPREQUEST on ath0 to 255.255.255.255 port 67 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 6 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 11 5 bad udp checksums in 5 packets DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 8 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 12 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 11 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 9 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 12 No DHCPOFFERS received. ----- sometimes I get this output: ---- sit0: unknown hardware address type 776 sit0: unknown hardware address type 776 Listening on LPF/ath0/00:0d:54:98:ad:00 Sending on LPF/ath0/00:0d:54:98:ad:00 Sending on Socket/fallback/fallback-net DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 6 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 11 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 11 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 14 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 18 DHCPOFFER from 192.168.0.31 DHCPREQUEST on ath0 to 255.255.255.255 port 67 DHCPREQUEST on ath0 to 255.255.255.255 port 67 4 bad udp checksums in 5 packets DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 7 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 14 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 14 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 14 DHCPDISCOVER on ath0 to 255.255.255.255 port 67 interval 12 No DHCPOFFERS received.

I also tried it with a static ip, but network still unreacheable. The laptop that works with the cardbus is a "nec zds versa note" (pentium II 400 Mhz) and the laptop that doesn't work with the cardbus is an "acer travelmate 524TX". I hope you can do something with this info. Please ask for more if needed Greetings Hendirk |
