Hello everybody. :;):

I've just ran DSL on a Tecra780 (64 MB RAM).

The internet connection is not working

. I use a DSL router to which two OSX computers are connected through WLAN.

I have a PCMCIA Fast Ethernet card installed.

eth0: RealTek RTL8139 at 0x488d0000, 00:10:60:76:xx:xx, IRQ 0
eth0: Identified 8139 chip type 'RTL-8139C'

> ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:10:60:76:xx:xx
BROADCAST MULTICAST MTU:1500 Metric:1
...
RX bytes:0 (0.0 B) TX Bytes:0 (0.0 B)
Base address:0xd000

It should work through DHCP but it doesn't: the network is unreachable. I checked the cable (I connected one of the OSX computer through Ethernet: it worked).

Any one has an idea ? Thanks in advance.

maybe your access point is to far away cause everything seems to be installed correctly download wavemon from the repository and see if that shows a signal str. if not that maybe the connection is encryted

I am still fairly new to linux, however I have had similar issues with a Satellite 2100CDT. Mine is set up to dual boot into that "other" os and DSL. In my case the bios settings had to be set to 16 bit cardbus. In your case (with 32 PCMCIA ?) it should be on auto or 32 bit.

As DSL starts, you should see the card aquire an IP address from the router.

Sounds like you're having a similar problem to what I have had. More or less, it seems that everything works. iwconfig gives everything it should. The data looks good, and the LED indicators show link. But no data moves. It's almost as if wlan0 is firewalled in both directions, or route is screwed up. You're not alone. I've found this problem on lots of forums. Nobody has, thus far, found a fix. Any real gurus wanna give this one a shot?

When booting up the network should detect DHCP automatically and get an IP number. How many leases does your DHCP server allow?

What happens when you right click->setup->net setup->netcardconfig and select yes for DHCP?
Does it say there are no valid network cards or does it think for a while and try to connect?

What happens if you remove one of the macs from the newtork and manually add the IP address of that mac to your dsl box (using the above netcardconfig and NO for dhcp)?

When you do sudo ifconfig eth0 you should get an IP address listed like this:

eth0 Link encap:Ethernet HWaddr 00:50:04:E8:84:67
