Thanks in advance!!

 Shocked  So all the data on this test is understood by you? Maybe its me but it would seem like you would have had a question about the context of the data sooner than the fourth line b4 the end....This value is a theoretical value that limits throughput due to the size of the buffer(125) although I am under the impression you would wish to change this value to somehow make your connection faster you would be mistaken if you think this will work.It will in no way help you to try and reconfigure this or many values give with this hypothesis, furthermore alot of the text in this information is rated "TOP SECRET" by the government of the United States and since I hold a valid security clearance from the U.S. government I would be compelled to terminate you with extreme prejudice if I were to divulge anything further to you concerning this matter. I'm sure you understand.... of course thank you for your interest in this matter and in the future if I can be of any help to you feel free to ask me. I will try and answer any question I am allowed to answer with the current constraints placed upon me by the U.S. , and I know you are just as concerned with secrecy during these trying times  we now live in. Thanks for visiting and tell your friends to visit.

Hey Mike Smile

I think it refering to CurRwinRcvd: 128480

In cablenut you have that value in TcpWindowSize or DefaultReciveWindow

even tho it says 125 KByte

I dont know much about routers, but do you have a duplex setting in the WAN port?

try setting it to 100 half

and run the test again, also compare speed against testmy.net

strange... it didnt change anything, the ports on router should run at full duplex, only the port that goes to modem that should run half duplex on cable.

you have to test at non peak times to keep up the stats .s1, i will do that from now on  ;)

its probl nothing to worry about since the speed is there, but it would be intresting to know where the duplex mismatch is located hehe

hehe i her that.  Been talkin with ca3le, he seems a little more motivated now to switching testmy to a less traffic route ( very badly worded...but its 1 am...screw it )
