Hi All,
Thanks for reading this.
I have an adsl router (Huawei). I have connected to the router through wifi but I still cant ping it. In kWifi manager, it shows me as connected, and also in the router, I can see my mac address as connected. But still cant ping.

I am using Slackware 12.0

But I cant ping my router. Please give me some suggestions.

Thanks for reading this post.

just a thought
ping is blocked at the router by the firewall?

If you have your wired LAN connection and wireless connection to the same router, you will have problems. I don't know if this is the ONLY problem, but you need to disable the wired connection if you want the wireless to work correctly.

It appears you have both connected to the same router, or at least the same subnet and that generally is a problem.

Hi Pentode, Repo,
Thanks a lot for your super quick replies. Unfortunately, I was out of town for an emergency and I could not do anything further. I returned, and checked the router again, no firewall problems.

I changed the IP for the wifi. It would connect only in peer to peer mode, but no ping to an external IP would work.

With the same ip subnet, I checked and the default gateway used the lan port. Hence, I was not able to ping the router using wifi. I did a eth0 down, then add the default route back.

And it worked!

Thanks a lot both of you for your suggestions. Unless you did that, I perhaps would not have been able to solve the problem.

Thanks a lot again.

With warm regards,
Vivek.
