No Internet after last Pacman Upgrade

I did a Pacman -Syu about ten days ago and haven't used our Linux machine since that time.  Upon restarting it yesterday, we have no connection to the internet.  This is with a hard wired ethernet connection not wireless.  We have dual boot setup with Win7 and we get internet there with no problems.  I'd really appreciate some help diagnosing the problem.
Thanks

Re: No Internet after last Pacman Upgrade

You need to provide some more info in order to get people to assist you.
For example: what's the result of ifconfig, what type of configuration you have to the web (ie: is it a direct connection or via router), firewalls, etc.

Without any other information it will be difficult for someone to help you troubleshoot.

Re: No Internet after last Pacman Upgrade

Hi Sorry,
When I run ifconfig I get
eth0   Link encap:Ethernet HWaddr " "
          UP Broadcast Multicast MTU....
          Rx Packets:0 ...0 ...0 ...0
          Tx Packets:0 ...0 ...0 ...0
          Collisions: 0 , ....0
          Interrupt:54 Base add...:0x4000

lo       Link encap: Local Loopback
....

Checking my /var/logs/errors.log
I see;
localhost dhcpd[1364]: timed out

I try /etc/rc.d/network restart.
It stops the daemon fine but is unable to restart it and shows fail on "Starting Network"

I have an Apple Extreme Base station router.

I see on bootup now that Network daemon just won't start.

Thanks again

Re: No Internet after last Pacman Upgrade

Doing a lspci -v I find that I have the realtek r8169 module.
with dmesg | grep r8169 I get:
r8169 Gigabit Ethernet drive 2.3LK-NAPI loaded
r8169 ...
r8169 ...
r8169 ...
r8169 ...
r8169....
r8169 0000:03:00.0: eth0 link down
r8169 0000:03:00.0: eth0 link down

I then try sudo ifconfig eth0 link up
"link: Host name lookup failure"

Re: No Internet after last Pacman Upgrade

According to ifconfig your card is not recognized ... you do not get even a hardware address.
Try this:
1. ifconfig eth0 up
2. ifconfig (to see if you get a card added to the system)
3. if you do then run dhcpcd eth0
4. then again ifconfig (see if you get an address)

Re: No Internet after last Pacman Upgrade

I type ifconfig eth0 up
then
ifconfig I get:

eth0   Link encap:Ethernet HWaddr 1C:6F.......
          UP Broadcast Multicast MTU:1500 METRIC:1
          Rx Packets:0 ...0 ...0 ...0
          Tx Packets:0 ...0 ...0 ...0
          Collisions: 0 , ....0
          Interrupt:46 Base address:0x6000

lo       Link encap: Local Loopback
....

Btw. my motherboard has a Realtek 8111E Ethernet controller.  lspci -v shows that a module for realtek 8169 is loaded should that be the case?

Re: No Internet after last Pacman Upgrade

I think maybe the kernel that was upgraded doesn't load the ethernet drivers correctly or something.
Is it possible to download a new version of the kernel from the packages database here with the headers and just do a pacman -U local upgrade?

Re: No Internet after last Pacman Upgrade

UPDATE: Actually, my problem turned out to be at ISP end.

Sorry to butt in but I've similar problems, only in my case ethernet does have hardware address and things look normal (no errors in logs), just can't get IP. This problem appeared between last night and this afternoon, without me using the net connection in between.

Hardware (vdsl2 modem and basic dsl router) seem normal, all lights on (yes, checked cables). Reboot/restart of hardware/network/networkmanager, no effect.

Dmesg on eth0 (ethernet):

bridge-eth0: up
bridge-eth0: attached
eth0: no IPv6 routers present.

Sorry I can't paste outputs as I'm writing this on cell phone. Nothing whatsoever changed since last night. I ran updates last week, including latest kernel + headers but had no network problems until now.
