[SOLVED] New 2010 install - Wifi works, wired doesn't

[JerryP]

Maybe this should be under networking but that is not factually my interest. I just want my DSL connection.

After installing PCLOS 2010 on a new hard drive my LAN card is recognized and the network interface wizard in the control center congratulates me but what I restart X there in no connection. I removed it and installed a wifi connection instead and that worked just fine. I can reboot with my PCLOS 2009 and the DSL connection is just fine too. Seems like something with 2010 and the LAN card interface.

I think it must be pretty simple to fix but I guess I'm a little too simple.

Hi jerryp

You mentioned "I removed it and installed a wifi connection instead and that worked just fine"

Just to clarify - you say you removed and setup the wifi connection; did you also try removing and reinstalling your LAN connection?

If you haven't tried that, give that a go.

ps, on my system I noticed during the 2010 beta testing period that it took a while - 30secs or more - for my LAN connection to kick in properly after I first logged in or after I changed any settings.

"did you also try removing and reinstalling your LAN connection?"

Innumerable times and trying things turned on, turned off, you name it. Nothing seems to fix it or make it different. The system says it should be fine but it won't connect to the internet. No connection with Firefox, Synaptic or BitTorrent and my firewall is OFF (as best as I can tell).

I "cleverly" started looking at system services thinking that there might be something off that should be on and vise-versa and discovered WLAN was stopped and wouldn't start no matter what I did so I rebooted to my 2009 to see if that was different and was disappointed to find that WLAN service there wouldn't start either. So that isn't it. And BOTH 2009 and 2010 say the NIC is working and that the network is up. The only difference seems to be that 2009 connects to the Internet and 2010 doesn't.

Since it's "only" annoying at this point (I'm installing 2010 on a new hard drive and have the old hard drive a USB enclosure that boots) I will format / and /home and try it again from scratch but I'm not hopeful.

Sooooo if anyone thinks of anything for me to do - help!  There has to be something stupid I am overlooking and I am not unwilling to feeling chagrin.

Oh, and one other seemingly odd thing that doesn't seem like it could relate is that ctrl-alt-backspace just beeps and doesn't end the session. Really weird.

Have you checked cables are plugged in at BOTH ends?  (gotta ask    )

Could try restarting your modem/router (switch off for 30 - 60 secs) and turn it back on. I sometime reboot my machine as well when I do that.

Have you been into the PCC > Network & Internet > Network Centre > Click on the arrow at the side Wired Ethernet icon > Configure > and see what you have in there. (You have to scroll down a bit to see everything)

Is the Automatic IP  "radio button" selected?

Could always use OpenDNS numbers instead of having the DHCP Server set it
DNS server 1 address : 208.67.222.222
DNS server 2 address : 208.67.220.220

At least you can tick them off your "check list"

So your LAN card is working (2009 confirms no hardware fault) but  2010 has a hiccup.  "Ping" is the first command to use at the CLI to see if your connection is doing anything.  Are you using a router? Static IP address or DHCP?  What does "ifconfig"  at the CLI show? What does "route" at the CLI show?  Execute these commands as root, they will show you if your NIC has a working configuration and a default gateway (typically your router).  Check the contents of /etc/resolv.conf has teh corect DNS entires.  You should be able to configure your NIC at the CLI if the hardware is correctly detected, and then troubleshoot the problem.

 If you do find you can ping and not surf, it could be you have a firewall blocking your connection.

OK, somehow I fixed it and even made notes but being a jerk they are too cryptic for me to even read. What I can tell I did was went though the services of the 2009 system and compared them to the 2010. Naturally the 2009 had more services than 2010 since I have been using it for a couple of years and carping it up. But on 2010 I had to turn on netfs, smb, mysqld, named, resovconf and portmap.  I then set my firewall on the 2010 to match the 2009 and only allowed SSH Server, Windows file sharing (SMB), Cups server and BitTorrent. I also disbaled IPv6 to match to 2009.
Then noticing that my time was not right I replaced my CMOS battery and since I had the box open I checked all cable connections.
I appreciate all the help and if it looks like something above might have been more likely than something else to affect the fix I would like to know.
Thanks.
