My wireless is making an association with my AP, but TCP/IP traffic doesn't seem to want to transmit over it; I can't even ping my AP. TCP/IP works fine on the ethernet adapter. Wireshark (without the ethernet connected) only shows traffic going out the wireless card, not in, and another station on my home network is not seeing the DHCP broadcasts. My access point can see the MAC address of the wireless card in my laptop. I've tried to config the networking with DHCP and static IPs, neither worked. So, the wireless card appears to be working, and TCP/IP appears to be working, but not together. Does anyone have any idea what could cause this? I've previously had it working, however, I forgot to grab my kernel config before I wiped the drive, only the /etc folder and my home folder, so there's a good chance that I've done something differently in the kernel config. Use portage to rebuild all the relevant network ebuilds. I've had similar trouble with NetworkManager and my wireless after rebuilding lots of the system, and once I rebuilt NetworkManager then everything was back to normal. So, dhcpcd certainly should be rebuilt, and whatever other things might be related to the wireless in portage. ~daid Well, I've used emerge -C and then emerge again on dhcpcd and iwl3945-ucode. I'm not sure if I did that with wireless-tools, but I'll try that now. Actually, I'll unmerge all three and re-emerge them again. Are there any others that I'm missing? I can't think of any other packages that would apply; at least, not that I specified. John Moe Well, nevermind.  It seems to have sorted itself out.  I'm not sure if it was the re-emerging of the three network packages mentioned before, but they didn't seem to do anything afterwards.  So then I noticed that FireWire networking module hadn't been built, and that was in there the last build, so I switched CONFIG_IEEE1394_ETH1394 to <m>, recompiled the kernel, copied it over and rebooted, and suddenly the wireless started working.  Could it have needed a reboot after re-emerging the network packages?  I can't see how adding FireWire networking support would change anything... Anyway, thanks for the quick suggestions.  It seems to be working now. John Moe
