mattmag Posted October 29, 2005 CID Share Posted October 29, 2005 Is it possible that a Motorola SB 5120 has a preset for MTU? I haven't been able to find a way to check this, as I am trying to determine what has dropped my MTU down to 1440. I'm on Mediacom cable, if that makes any difference. My registry has the proper DWORD value for 1500 MTU, yet all tests show it to be 1440. This happens on *any* machine on my network, so I suspect it is somewhere external to the machines. I also have Netgear router, which does have an MTU setting, and it is at 1500. Any info appreciated. -Matt Quote Link to comment Share on other sites More sharing options...

mattmag Posted November 8, 2005 Author CID Share Posted November 8, 2005 So I'll answer my own post again. Seems like it IS the Netgear Router causing the trouble. Took it out of the loop, and the MTU reports as 1500, so it isn't the cable modem. Not sure why the setting on the router says 1500 but is goes to 1440 yet... that's the next thing to figure out!
