WL1271/73 packet loss issue.

Hi,

I am using WL1271/73 with AM3505. We want both ethernet and wifi running simultaneously.

What I observed is the ethernet works fine (0% packet loss, testing with iperf) with ~25Mbps full duplex.

When the ethernet test is running and I start the Wifi (iwconfig tiwlan0 up) I see 100% packet loss on ethernet.

If I disable the wifi (iwconfig tiwlan0 down) I again see 0% packet loss on ethernet. So I feel the wifi is causing the ethernet packet loss.

Has anyone encountered such problem? If yes, what can be the problem here?

Regards,

Krunal

    try running "route" command for 0.0.0.0 (gateway).

    My guess is that doing the iwconfig tiwlan0 up change the routing tables and now packets are going to the wifi instead of the ethernet port.

    I'm using both ports (ethernet & wifi)

    Hi,

    Thanks for the inputs.

    I figured out the problem was with the Pinmuxing with the ethernet enable pin of the switch.
