 Posted: Tue Feb 26, 2013 2:33 pm Post subject: Cannot connect to router from LiveDVD or Minimal |
 |
|
Hi, I just built a new computer and I booted it up with the amd64 LiveDVD and I cannot get a valid IP address from my router. I've even tried to set an ip on the new machine and it still can't talk to the router. Instead, when I try dhcpcd it generates a default ip address 169.254.x.x and whines about an ipv6. I tried putting noipv6rs in the /etc/dhcpcd.conf but it still doesn't work.
If it helps but mobo is a Gigabyte GA-970A-DS3 and yes, I checked if the onboard LAN was enabled in the UEFI BIOS, also I checked the cable and it works. The onboard LAN (Realtek GbE) is detected properly during boot I think. As per this thread I thought it may be a kernel issue so I tried the amd64 minimal install disk but I get the same results.
It still may be possible that there is something wrong with the kernels on these latest ISOs so my only thought so far for a work-around is to get a wireless USB NIC and try connecting to the internet using that.
Is this a good approach or am I completely out to lunch?

OK cool, I'll try that when I get home tonight. Incidentally, does the LiveDVD (or minimal) support usb wifi devices? I'm thinking of picking one up just in case. Or should I go with an internal NIC just to be safe? Thanks.

I found this discussion which may indicate that there is a problem with the mobo firmware:
http://ubuntuforums.org/showthread.php?t=2111223&page=2
In posts #16 he says this:
| Quote: | Issue 1: The system boots and installs normally with any 32 bit OS, but when a 64 bit OS is installed the network card no longer functions correctly or at all. This has been seen in only intel / realtek built-in nics so far regardless of board make and model.
Solution1: Turns out that for about a third of these the problem is that there is some sort of bug in the nic itself so that the 64 bit Linux OS identifies the built-in as eth1 instead of eth0 and the interfaces file is built by default for eth0. Altering the file to reflect eth1 instead of eth0 resolved this 90 percent of the time. |
I noticed that in /etc/init.d there was a net.eth1 through net.eth4 but there was no net.eth0. I tried to copy net.eth1 to net.eth0 but it didn't seem to work. I didn't have time to investigate further. Red herring?
His Solution2 is basically what I am thinking of doing. And Solution3 would be a problem because I don't own a copy of Windows and have no intention to install it just to update the mobo firmware... I will check if there is any new firmware on Gigabyte site. Anyone have any tips on installing firmware that needs Windows to flash?
Thanks.

Or should I just return this mobo and get another one...? Do you think the problem will be eventually fixed?

When I manually set an ip with and set the gateway as my router address and then ping that address I get the following error: "no buffer space available"
I've never seen that one before...

| Issues with the 8168 NIC are not uncommon. Realtek provides an out-of-kernel driver for it, it's even in portage - the r8168 package. Get that installed, and compile a new kernel that does not include the r8169 driver you're using now. |

I use this one from kernel.
But now i remember....
To make it work i had to emerge sys-kernel/linux-firmware |

Interesting. I have a similar NIC (rev03 instead of rev06). It will load the firmware if present, but it'll also work fine if the firmware is not there. But definitely good idea, the firmware could do the trick for the rev06 models. |

I haven't had a chance to try it yet. I will tonight when I get home.

Ok, the system rescue disk doesn't work either. Is there a way I can edit a LiveDVD kernel or build a custom one that has the appropriate driver options?

I tried this last night, it didn't work. Please see my reply here.

You can play with sysresc boot options.
What have you for messages in the logs about eth0 ?
Its is strange that no one of boot nic work !!! |

So today I went and picked-up a wireless usb stick. I thought for sure that it would work with the LiveDVD but it did not! I couldn't get it to work in the resuce disk either! Does anyone have any idea of what's going on? I've tried wireless-compat and other drivers. *Nothing* is working!! Can someone suggest a rock-solid NIC or wireless NIC that will work with these live DVDs? Or should I just ditch this Gigabyte mobo and get and ASUS one? I've spent hours trying to get something as simple as networking working properly!! (sorry, I'm a bit frustrated if you didn't already notice :-P)

What does ifconfig show ?
Think that those buffer errors might have something to do with wrong (to large) MTU values for the buffer of your network interface. |

i had a gigabyte motherboard, for 4 months before it caught fire.... ASUS has been rock solid for me 
ifconfig -a
will show all interfaces even down ones. it might be eth1, though id rather be safe than sorry, and return the motherboard. |

ifconfig -a shows the interfaces but only shows one of those 169.254 default ip addresses. How do I fix the buffer stuff?

But what does it say about the size of packages?
Should be something like tihis, thew MTU part is the size of the packages. If those are set to bigger then 1500, your buffer might not be big enough.
| Code: | # ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.0.30 netmask 255.255.255.0 broadcast 192.168.0.255
inet6 fe80::52e5:49ff:fe4f:c3c3 prefixlen 64 scopeid 0x20<link>
ether 50:e5:49:4f:c3:c3 txqueuelen 1000 (Ethernet)

I will check when I get home. In the meantime I purchased a wired *and* a wireless PCIe NIC. One is Intel and the other is an Asus that supports "Linux" (whatever that means). There is downloadable firmware (i.e. .bin) files so maybe this is something that will work since the LiveDVD documentation explains pretty well how to install firmware. I will report back...

Can you send the output of :
(if not installed, please emrege net-misc/dhcp)
If you see eth0 in the output of ifconfig, it seams that the interface works, but there is a network configuration issue.
Are you behind a router ?
If yes is it configured as dhcp server ? |

| The minimal install CD doesn't have any wireless firmware, so it's basically useless for wireless installs. Use SystemRescueCD instead. But, as always, post "lspci -nn" output (the -nn is important!), that's the only way you can determine which driver is needed. For the Gentoo install, most wireless firmwares are in the linux-firmware package, so make sure you'll have that installed. |
