dropped package question.. my DIR655.. (tried 2.07 and 2.11 both same) keeps have entries like that:
[ 974.680000] '[DROPPED-PACKET]:'IN= OUT=br0 SRC=192.168.1.1 DST=192.168.1.51 PROTO=ICMP TYPE=3 CODE=3

my router in 192.168.1.1
so, that mean the router keeps sending icmp package to one of my internal machine?  and it drops that package?  what does that mean?

the other question is more annoying.. the routers keeps dropping internet connection every 30 mins or so.. however, it will recover itself after a minute or so..

I tried disabling QoS.. but still same.. and ... I hope to keep using QoS and that is the purpose of me getting this router in the beginning

I had 6mb service before but it never like this.. since changing to 25 mb service, I have issue the drop connection issue.. does not router not capable of handling the 25 mb service?

please advise.

Link>Welcome!

  • What region are you located?
  • Are you wired or wireless connected to the router?
  • Was a Factory Reset performed before and after any firmware updates then set up from scratch?
  • Was the router working before any firmware updates?

Internet Service Provider and Modem Configurations
  • What ISP Service do you have? Cable or DSL?
  • What ISP Modem Mfr. and model # do you have?
  • Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values


Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router.
  • Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS or Gamefuel. For the DGL-5500, review this for Streamboost information and settings: Furry's DGL-5500 Review
  • Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
  • Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
  • Turn on DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench
  • Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
  • Ensure devices are set to auto obtain an IP address.
  • If IPv6 is an option on the router, select Local Connection Only or Disable IPv6 options under Setup/IPv6.
  • Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Enable or Disable SPI to test.
  • Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Enable IPv6 Multi-cast Streaming for routers that have a Media Server option. Disable IPv6 Multi-cast Streaming if IPv6 or Media Server is not being used.
  • Turn off WISH, and WPS under Advanced.
  • WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed
  • Set current Time Zone, Date and Time. Use an NTP Server feature. Tools/Time.
  • Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.

Well you know if you have read my posts before that others fill in the questions and give feed back so we can get a better idea of what you have so we can give you better feed back and suggestions. Kind of hard to help you trouble shoot the problem with out a bit more info. These questions are pertinent and relevant to the situation.
