VanBuren Posted January 6, 2005 CID Share Posted January 6, 2005 My question is this:Your PC/Workstation has a 125.0 KByte buffer.........what is meant by that?? Hey Mike I think it refering to CurRwinRcvd: 128480 In cablenut you have that value in TcpWindowSize or DefaultReciveWindow even tho it says 125 KByte VanBuren Quote Link to comment Share on other sites More sharing options...

VanBuren Posted January 6, 2005 CID Share Posted January 6, 2005 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 VanBuren Quote Link to comment Share on other sites More sharing options...

VanBuren Posted January 6, 2005 CID Share Posted January 6, 2005 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 VanBuren Quote Link to comment Share on other sites More sharing options...
