Packet Loss with CM1200
So I've been getting really bad packet loss, after using ping plotter from my PC to trace the issue, I believe I've narrowed it down to the CM1200 modem. This is what my setup looks like.. modem...
I didn't get a snip of the connections page or logs. I logged into my modem last night and didn't see anything like that. I'm at work and could attempt again in a few hours when I"m home.
and correct, that's how I have my setup modem > router > switch
Here's a screen shot of my PC plugged directly into the modem. For some reason it's appearing as that 10.xxx.x.x IP address but when I ran an IP config when plugged in it came back as a different IP.
Also wanted to point out that the response time with the modem according to ping plotter seems higher than it should be, even when plugged in directly!
Thanks!
try this ping test. I've never used the you you're showing

very hard to compare like that. if you're on windows, theres a screen snip function that lets me look at it much easier.
