Cable Modems Half Duplex..

[Philippine Mango]

I don't know if this is the fault of the router I'm currently using or not but apparently my router is detecting my cable modem as 10mb half duplex despite the fact I could've sworn it would say 100Mb when I connect it to a computer... So is the computer wrong or is the router detecting the true connection the modem outputs?


Are all cable modems half duplex? How bad is this for performance? I'd imagine it'd be pretty bad if you're downloading and uploading at the same time, right? Do they have full duplex modems? How do you find out?

Does it matter? I can't believe that your cable connection is more than 10 megabits...

I'm more worried about collisions than anything else...

many many WAN ports on even some high end routers are only 10-Base T I wouldn't worry about collisions, they are going to happen on the providers network if at all (which it's pretty non existant now adays but does happen) you're not going to get any between the WAN and the modem as there is nothing to collide and the network protocol is designed to avoid it.)

You can't have collisions on a point to point link (between your router and the cable modem).

Cable has broken 10mbit.

Comcast premium tier people are getting 16/1, some are getting 16/2 if they have FIOS nearby (to prevent FIOS from stealing customers).

I personally have gotten up to 32mbit susatained (for hours) over my cable modem.
