I have been trying for about a month to get wireless working on my laptop, with little success. Everything from ipw2100 drivers for the build in Intel centrino, to ndiswrapper for Linksys USB external device and PCMCIA. Currently I have no idea what is in the computer, whats installed, what isnt, which driver support is in the kernel which modules have loaded. I sorta just gave up about a week ago. The /etc/init.d/eth1 device wouldnt start because of some problem with the wpa_supplicant.conf some error loading up, anyway, yeah it wouldnt associated with my router or pull an IP address off.
I could start posting all the errors and configuration files, but what I wanted to say was that today I noticed that I was connected wirelessly and through my ethernet connection. I thought.,.. that cant be! So pulled out the network cable, and tried to continue working on the internet, new websites, new chat conversations, I WAS ONLINE! 192.168.1.110 IP got pulled from the router somehow, which is somewhat odd since the other devices are 101,102,103,104 respectively, why the sudden DHCP jump to 10. And um... yeah. So now I've obviously done something in the last month which I didnt realise, and now I dont know what it was or how I did it! Annoying! Can I do some forensics work to find out at what point, day time, after which changes my wireless access started working?
Also, today I added an entry in /etc/conf.d/rc and when I restarted I get an error saying that the time modification for this file or an init.d script is in the future. Ive since removed the entry, but how can i fix the error that i keep getting?

Try:
[code]grep eth1 /var/log/messages[/code]
You will see info about that interface from the past. Try to see when it started working. |

you can also do an 'lsmod' to see what modules are loaded and which ones are in use.

Well... airo and ieee modules are the only things I can think of related to wifi. They dont seem to be loaded.. So what on earth is going on??
Tried the logs as well. Seems like it was always connecting, but that doesnt make much sense because I was checking ifconfig/iwconfig regularly when i played around with it and i never saw that eth1 had acquired an IP address:
Nov 5 21:06:10 thinkpad dhcpcd[30393]: eth1: probing for an IPV4LL address
Nov 5 21:06:10 thinkpad dhcpcd[30393]: eth1: checking 169.254.73.102 is available on attached networks
Nov 5 21:06:10 thinkpad dhcpcd[30393]: eth1: sendto: No buffer space available
Thats part of the log file which is still pasting (until i can figure out how to get it to print out all references to eth1 after Nov 21 at say 2030 I recoginize that 169.* from a windows problem I once had, where it fails to pull the a correct IP from the router and TCP/IP has to be reinstalled over itself. No idea what that means for linux..

To print all references to eth1 after (and including) Nov 21 at 20:30, you can do this:
| Code: | | grep -A 999999999 '^Nov[[:space:]]*21[[:space:]]*20:30.*eth1' /var/log/messages |head -n 10 |
The only problem is that there actually must be an entry for eth1 at that time in the log, otherwise it will fail. |
