[SOLVED]Network not working after update

Hi there.!

I had a perfectly running Arch install on my laptop (Dell Inspiron 14R) until I did a pacman -Syu few days ago.
Failing to see that pacman had found a kernel update, I let it do it's rolling release magic only to reboot and be dumped ungraciously to a tty.!
Poking around a bit, I found that I needed to rebuild my fglrx module against the current kernel.
Fair enough, I said and tried to get online to see how I go about rebuilding the module, only to discover that my Wi-Fi was down too.Damn.!
A bit more poking around revealed that I needed to rebuild the wl module too for the new kernel.Ahh, the joys of using proprietary drivers for all things.!
Anyway, with only one option left now, I got into the attic and wiped the dust off an old Ethernet cable.Connecting my laptop to my router with this contraption, I finally hoped to see the back of all my update woes only to find that Ethernet wasn't working either. The network service plain fails to start.dhcp always times out while "broadcasting for a lease" (methinks dhcp is what fails in network service too).I tried reserving an ip fin router settings and assigning static ip with both dhcp and rc.conf, connecting my lappy directly to cable modem but nothing works.
The ethernet controller is Atheros AR8152 v.1.1 and uses the atl1c module included in the kernel.
Any help.?

Check what dmesg has to say about atl1c and/or eth0.

Can you see eth0 in ifconfig -a?

Re: [SOLVED]Network not working after update

dmesg | grep -e atl1c

atl1c 0000:05:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
atl1c 0000:05:00.0: setting latency timer to 64
atl1c 0000:05:00.0: version 1.0.1.0-NAPI
atl1c 0000:05:00.0: irq 43 for MSI/MSI-X
atl1c 0000:05:00.0: atl1c: eth0 NIC Link is Up<100 Mbps Full Duplex>

grepping eth0 yields only the last line.
Looks fine to me.
eth0 shows up in ifconfig but expectedly, doesn't have an ip assigned as dhcp always times out
I am stunped as to what is causing the network failure.

Re: [SOLVED]Network not working after update

I am so stupid that I should probably have the word stamped on my forehead with my own blood.:

Reason for all my 'troubles': MAC filtering. Had enabled it for my wireless interface and other devices. I never felt the need to add my wired NIC to list of allowed devices..... until now
