Here's my problem -- I have a wireless connection "working". That is, I can ping my other computers. One of the driver authors says that means the driver is working.
My computer has both a network card and a wireless card. The network card is eth0.
Eth0 works perfectly.
The wireless is eth1. As mentioned, it will ping the other computers. But, I can't reach the internet and I can't use linneighborhood to see my windows computer, as I can with eth0.
The driver author suggests that I have a problem with my network settings. I have rechecked them several times.
I >had< the wireless working before the system crashed requiring a clean install.
What steps could I use to determine what is >not< working? I've tested the ability to "ping" other computers, got that running. I've run lsmod, ifconfig and iwconfig. These seem to report the right stuff, though I'm not truly sure what I am looking for.
Mandrake network wizard reports both eth0 and eth1 as working, though eth1 will not connect to the internet.
Well, they are both "loaded", but the connection is made on whichever is active. I tried switching the gateway. It doesn't seem to make much difference. Making the default gateway eth1 doesn't activate the wireless card and it also doesn't >deactivate< the ethernet card.
Yes, my gateway and DNS is a router/wireless and I can ping it. Ping is about all I can do. I'm completely baffled, since I thought in theory that if you could ping, then you were sending and receiving data, so that if your network software was set up correctly, things would work.
I have used the system monitor to watch the packet traffic -- lots of traffic on "ping", no traffic if I run any actual attempt to access the network.
My guess after a good deal of reading, and considering it worked in a prior install before crashing, is that there is a problem in the kernel/modules. I guess I will try re-compiling the kernel, for lack of any other ideas at the moment.
I would suspect it is a routing problem. You can ping the
gateway machine because it's 'local' to you and the routing
knows where it is, but got anything else it has no idea
and so just ignores them.
Check the output of the command:
route -n
I think you need a line that specified the IP as 'default'
and that specifies the gateway IP. Read the route man
page and or the networking howto on how to set it up
if there isn't that line.
