[General] Intermittant Connection dropout ~60 seconds.

Hello,

I have a zyxel 645 UHP modem bridged to a DLINK 605L router and using the Earthlink DSL through an AT&T line.

About 4 or 5 times a day, I will suddenly start getting 404 errors for any connection to a web page. This will last for about 1 minute, and then it will start working again.

My router log shows this when it happens (an example):

Apr 14 20:36:54
Manual Hangup Disconnect PPPoE line

Apr 14 20:37:27
System ACK Flood Attack from WAN Rule:Default deny

Apr 14 20:37:27
Per-source ACK Flood Attack Detect (ip=180.233.141.9)
Packet Dropped

Apr 14 20:37:27
PPPoE: Sending PADI

Apr 14 20:37:27
WAN Dialup Try to establish PPPoE line

And so on until the connection is re-established about 40 seconds later.

This problem started happening right after I switched the modem to bridged mode and started using the new router to do the PPPOE connection. Prevously I had a different router that I only used as a switch and had the modem doing the login and this worked fine but I needed wireless so I bought a new router.

I constantly get the "Flood attack" messages, about once every minute.

Any suggestions?

Thanks.

Remove the Router and use the Earthlink supplied Modem. If the problem goes away, it is your Router.

I ended up switching back to using the modem to do my PPPOE login, and set the router up as an AP connected to the modem. Have not had a disconnect since.

Congratulations on your success!
