On Board Realtek GBit only running at 1Gbit


I'm trying to install Ubuntu on a new system, I have an Asus M3A78-EMH HDMI Mobo, with and AMD 64x2 Athlon. The Livecd wouldn't run at first without a little work, (setting my monitor params, and removing the splash from the boot line etc). When it finally did come up, I couldn't connect to the internet because the box hadn't got an IP from DHCP. I tried getting a connection with no luck. I thought I might have better luck to install the OS, so that any chnages might be fixed and would be picked up on a reboot. Well the install went OK, but still no IP. On further investigation I discovered:

the Realtek Gbit card is only working at 1Gbit speed. Because I'm such a Newbi, and I'm not at the machine right now, I can't remember the command which I ran to dicover this (ifconfig, ethtool ?? ) anyway the adapater reports that it has a Fiber connection. With this type of configuration, I believe the device will ignor any speed settings with the ethtool -s command.

As long as the Lan adapter is waiting for 1gbit data, I'll never get an IP thru DHCP on my 100mBit router.

Does any of this make sense. Is there a newbi way of forcing the Realtek into a 'Copper' (TP?) mode so thjat I can set it to 100mbit?

Thanks

Thanks, I'll try this. I quess for Ubuntu, I should follow the Debian steps? Just one thought (actually way more than 1) since I'm basically vi'ing a file to include ethtool command line to change the speed of the NIC, will these work when the NIC thinks it has a Fiber connection rather than a copper one? I had read, and experienced 1st hand when I tried to set the NIC to 100 mB Full duplex, that since the NIC is set to Fiber, the ethtool speed commands don't work.

I did a work around for this by installing a wireless NIC I had, and I got the box to get an IP from the wireless card. I had set up dual boot, and XP finds the net thru the Realtek, and Ubuntu uses the Wifi. I'll play with your suggestions, but the panic is off, and I'm now surfing and configuring aps and updates.

I guess I should start a new thread for this, but my problem now is getting DVDs to play. I'm thinking about dropping down to the i386 distro, but I'm not sure that the 64bit version is cause the codec problem. I got wmv and mpeg to work, but VOBs are a no go.

I'm not sure I know how to reverse the build to jump down to a 32bit OS. Can I simply re-partion the linux portion of the drive and install a new i386 Ubuntu install? Will this clean up the dualboot screen or will it still indicate I have a 64bit version to boot dispite the fact I blew it out for the i386 build? I told you I had more than 1 thought. LOL.

I may reformat the whole drive and start over with a new XP build and then setup 32 and 64 bit Ubuntu partitions. I sort of screwed up when I didn't think out the partitions properly to start with. I should have added a FAT32 partition to easily allow file sharing between the XP and Linux.


Sorry for the 'off thread' ramblings.

Mike

For DVDs have a look here. The rest of your post seems to be thoughts, I don't see a real question. Try some things, read some things, post if you have a problem.
Good luck. ;-)

Thanks Peacedog, With a few attempts and a little reading, I got VLC to work.

I had actualy installed on my setup.
I am using Suse, but should be the same thing
You just have to unload the default realtek driver (r1..9.ko) and install the one included in the drivers DVD from Asus. (or just download them from them support web site
