Hi: I'd like to know why all Roku boxes constantly send ICMP Requests to port 137 to the Router. Why is there a need to constantly flood my router with ICMP requests?? -

UTC 12/15/2010 21:04:27.304 Notice Network Access ICMP packet dropped due to policy 192.168.168.133, 137, X2 192.168.*.*, 137, X2 ICMP Destination Unreachable, Code: 3

192.168.168.133 = Roku box
192.168.*.* = Router/Gateway

This is not normal. This has to be a design flaw in Roku's software.

I have to unplug the roku box every time when it is not in use because it constantly floods the router.

Resets and RMA's do not fix this issue. Is there a need that this Roku Box needs to icmp my router constantly???????????

Is this connected through wireless or Ethernet?

Also, what, in your mind, constitutes "flooding"? (how many ICMP requests a second are you seeing?)

Running a windows system on your net? 137 is used for netbios name resolution.

The Roku box is using its wireless connection to my wireless router via AES Encryption using Mac filtering.

how many ICMP requests a second are you seeing?)
Alot I will look at my logs when I get home from work tonight and paste here.



Thanks.

Your other thread in the General Discussion forum has a response from a Roku employee:
