Since updating to kernel-3.8.7-201.fc18.x86_64 on my KDE-4.10.1 desktop PC running Fedora 18 I have encountered broken network operation.

What I know:

  1. My wlan0 connection associates with my AP and receives an IP address
  2. "ip address show" and "ip route show" indicate that wlan0 has an IP and routes are assigned
  3. I cannot ping out from this system although it responds to incoming ping
  4. Any attempt to use remote services e.g. browsing, e-mail recovery and NTP client fail
  5. Disabling firewalld has no effect

Things I have tried:

  1. I have added an USB wireless adapter as wlan1 and that works fine
  2. I kept kernel-3.8.6-203.fc18.x86_64 and reverting to that does not fix the problem

Other observations:

  1. The KDE Network Management plasmoid does not always show other wireless networks in my vicinity just my AP and a nearby Hidden Network. This seems very inconsistent.
  2. Although I noticed this problem after updating to 3.8.7, the fact that the problem now occurs under 3.8.6 also suggests something else may be the cause.
  3. Other suspects might be NetworkManager-* and kde-plasma-networkmanagement-* as they have been updated recently also.

I am a little baffled as to where to look next. Any suggestions?

I'll answer this one myself as the problem turned out to not be fedora-related.

I was connecting to my wireless AP indirectly via a Wireless Repeater. I found that if I wired my eth0 to the repeater's ethernet port I could connect to my gateway and beyond.

Finding this, I cloned my eth0 MAC address in my wlan0 configuration settings and now all is well. This is one occasion where MAC address cloning is useful.
