Dir-600 ping-flooded, connection lost every 30 minutes
« on: December 15, 2011, 06:23:39 PM »
Hi... hope someone can help me

I bought a DIR-600 a couple of months ago. Days later started experiencing problems, connection would drop, and only way to restore connection was to reset the router.
It has its password configured, a secure wireless connection also configured, and Wan Ping is disabled.

Yesterday I called D-Link support, and they asked me to update firmware (from 2.03 to 2.05). I did, but problem still here.

Today I realized that there is a log section, and when I entered this is what I found

Code: [Select]

I guess someone is trying to hack me, and this ping-flooding is what causes my router's connection to drop.

Anyone has any idea of how to prevent this from happening?

Thanks in advance

I would call your ISP and ask them if they can help you block those IP addresses or find out what has been hitting your router and modem.

I would use Inbound Filter on the routers web page maybe to help block some of those IP addreses.

What is your firewall settings set for? Default?

I would call your ISP and ask them if they can help you block those IP addresses or find out what has been hitting your router and modem.

I would use Inbound Filter on the routers web page maybe to help block some of those IP addreses.
