OK Freepers, here's a fun one. Installed Mint 8 Helena on a brand new out of the box Presario AMD Athlon II X2 240 Dual core w/ 3 gigs of ram.
During installation it couldn't establish a wired connection. The only error dialogue I got was 'could not resolve archive.ubuntu.com
The modem etc all work fine on my Presario with Helena. After installation it would try to acquire a connection with no luck.
Please be patient with me as I am not linux or tech savvy at all. Many Thanks!!
ping
One, did it recognize the network card (presumably an onboard one) and install/configure the proper drivers?
Two, does the network card have a properly assigned IP address, subnet mask, gateway, and DNS server?
Three, is there a problem with the gateway on your LAN?
ping
(sorry, it had to be asked)
How did you configure your network. Static IP or DHCP assigned? Are you using network manager?
could not resolve archive.ubuntu.com
This indicates that you are having DNS problems. The network interface may be up, but I'm not sure.
Login to a terminal window, as the administrative/root user.
Enter this command: ifconfig
You should get something like:
eth0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx
inet addr:192.168.1.100 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: xxxx::xxxx:xxxx:xxxx:xxxx/64 Scope:Link

RX bytes:174643934 (166.5 MiB) TX bytes:539642311 (514.6 MiB)
Interrupt:5
Plus another one for "lo". But, if you have the eth0 entry, then you have a valid network connection, and it's just a matter of resolving your hostnames.If that looks good, enter this command: cat /etc/resolv.conf
It should have something like:
nameserver 8.8.8.8 nameserver 8.8.4.4If there's nothing, that's your problem. If you have other IP addresses, you need to be sure they are valid (and that's beyond my ability to do remotely).
BTW, those nameserver addresses are valid: use them if you aren't sure your's are working. They are the Google DNS addresses.
It shows the etho connection but not sure of anything at this point, I am new to linux and still trying to find my way around,surfed the mint forums but didn't find any answers. I only have one monitor and cable for the two so I may be back and forth.
I will try those commands and be back asap. Thanks!!
May give it a shot, Thanks.
The word “RUNNING” is very important in the ‘ifconfig’ output:
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
Getting an eth0 entry indicates that the software is seeing the interface. However, if “RUNNING” is not shown, then it is not configured correctly.
If the interface is “RUNNING”, then try: ‘ping 74.125.19.105’
This is a valid internet IP address (to google.com). If this works, then your gateway is set up correctly. And the problem is truly DNS.
Maybe it’s the dial-up modem it’s flagging. I don’t think the Ubuntus support them.
I will try that next, takes me a few to go from one machine to the other. Thank You.
Sorry, meant cable modem.
rx bytes-122.1 kb
tx bytes 1.8 kb
When I tried to ping google- network is unreachable.
subnet mask looked right if that helps...
Did the numeric ping or the text ping fail?
Found some info will try something else.
Thanks to all.
numeric ping.
