Hi all,

I have put OpenWRT from trunk r10081 and OpenWRT don't make PING to external Host.

Last Boot - no problems
ifconfig  - no problems
ping 192.168.1.1 - no problems
ping 192.168.1.123 - NO PING sad with OpenWRT OK with Original Firmware

Thanks.

When make a ping from other host and show the ARP table this host appear.

root@OpenWrt:/# arp -a

But if you make a ping from Openwrt to another host don't go to another host.

:?

Yes is the same case.

I see this post yesterday and tried this patch but don't work.  another suggestion ?

Thanks

dmesg on my wag354g (ar7 with tnetd7300 soc):

Fixed PHY: Registered new driver
cpmac-mii: probed
cpmac: device eth0 (regs: 08612800, irq: 41, phy: fixed@100:1, mac: 00:11:22:33:44:55)
cpmac: device eth1 (regs: 08610000, irq: 27, phy: 0:1f, mac: 00:11:22:33:44:55)

while yours:

cpmac-mii: probed
cpmac: device eth0 (regs: 08610000, irq: 27, phy: 0:1f, mac: 00:1c:10:bc:7f:ac)

My ifconfig:

eth0....
          Interrupt:41

Yours:

eth0...
Interrupt:27

Also, in my case:

root@OpenWrt:/# cat /proc/interrupts 
           CPU0       
  2:          0            MIPS  AR7 cascade interrupt

 41:        594             AR7  eth0

If I "ifconfig eth1 up" I get another interrupt #27...

Hi cyberstorm, yes mi CPU are tnetd7200 and have ethernet only and your CPU are tnetd7300 with 2 interfaces ethernet y wireless.

See this document http://focus.ti.com/lit/ml/spat013a/spat013a.pdf

                                                               wireless solutions

You have 2 interfaces eth0 ethernet eth1 wireless. But you have installed the module for run and active your ACX device.

 27:          0             AR7  eth0

In my case interrupt 27 are ethernet but in your case is posible that this are wireless.

The discussion might have continued from here.
