can't see local network, internet is fine

[mlacons]

My upgrade went well until I tried to access the other machines on my network. I can't ping anything inside my network. The internet is fine and I can ping both by address and name as long as it's not in the 192.168.1.x range. I can get out using my router at 192.168.1.1 but I can't ping it and my browser can't establish a connection to it. It almost sounds like a firewall problem but I've confirmed that ufw is unloaded.

Any help would be appreciated.
Thanks
Mark

Re: can't see local network, internet is fine

Hi mark,

Your output shows that both your wired (eth0) and wireless (wlan0) interfaces are active with IP addresses in the same subnet (192.168.1.0/24)

It has been my experience that *sometimes* the routing will become confused IF you have 2 interfaces on the SAME computer in the SAME subnet.

I notice that you are primarily using your wired connection. Maybe try to disable your wireless, leave your wired on, and see how that goes. You *may* need to disable wireless and reboot (without the wireless getting an IP) because sometimes even just disabling the interface is not good enough as the routing/arp tables will still remember it.

Yes, I disabled the wifi in the bios and it works. The wifi must not be supported, yet. I'll try again in a couple of weeks.
