Solved-Wireless issue with MSI laptop

aceofspades19 · 2008-11-16 06:26:37

Hi,

I installed Arch linux today from a cd I burnt a few months ago. I installed it and it detected my wireless card but for some reason now, even though it gets an ip from my router with dhcpcd, it can't ping the router or google. I confirmed that I got an ip by running dhcpcd with the -d option. When ever I try and ping my router, I get an error message saying Host unreachable and when I ping google, it says unknown host. I asked some people on #archlinux on freenode but they were puzzled about it too. I was hoping that some of the knowledgeable Arch users here would have an idea about what to do. I have been a slackware user for quite awhile, so I'm pretty familiar with the command-line tools, so you don't have to hold my hand, and I have used Arch a little bit before(albeit in a virtual machine).

Thanks in advance

you cant ping "google" use the ip xD

phunkedelik · 2008-11-16 06:46:10

also if you want to find google's ip do nslookup www.google.com

or if you just want to ping the addy dont forget to add the .com

update: ive been helping this guy out.... so far we determined that his card is working fine and he says dhcpcd is not giving errors. i told him to do iwlist scan to see if the card was working and its fine......

Ok, so I installed from the latest cd and the wireless works fine on the cd but when I installed it, it doesn't work ugghh

Could you give some details regarding your specific card (hardware info) + the outputs of the likes of: `ifconfig -a`, `iwconfig`, `route -n`, `cat /etc/resolv.conf` ?

I'm using the rt73 driver
here is the output of ifconfig -a

cat /etc/resolv.conf

All of the above are the same as when I run it on the cd and it works then, but not on my installed arch

The IP seems to be getting assigned to your eth0 interface rather than wlan0.

I don't see how that could work because I ran dhcpcd wlan0 and it generates a /etc/resolv.conf for wlan0

Looking at the output of `ifconfig -a` one can see that eth0 has the IP 192.168.0.2, but wlan0 does not have an IP. Try:

ifconfig eth0 down
ifconfig wlan0 up
dhcpcd wlan0

I'm having similar issues with the same wireless drivers (also an MSI laptop)

My connection will work and then stop responding and not finding the nameserver all of a sudden and I'm forced to reset it.
(take down the interface, and bring it back up and connect again)

Thank-you that worked
