I have a WRV200 that will start sending icmp pings to the broadcast address of my lan after a reboot. It usually will start a couple hours after the reboot starts out slow then builds up until the network slows to a craw then dies. I have the latest firmware, reset the thing numerous times (factory default), security is enabled both wired and wireless. Acts like a dos attack or smurf bug. I gave up on Linksys tech support after they recommended I go without firewall/virus protection. I think they released a bad firmware version (18.104.22.168) Anyone else notice this? Have any ideas on how I can make the crazy pinger stop! Iâ€™m about to buy a Netgear and feed this Linksys to my dumpster!
