dn0 Posted July 15, 2005 CID Share Posted July 15, 2005 This may or may not be a modem problem. RF issues can definitely cause a modem to reset frequently. What is your 'Power Level' under the Upstream section of the diagnostics? Also, what is your Downstream Signal to Noise Ratio? Quote Link to comment Share on other sites More sharing options...

dn0 Posted July 16, 2005 CID Share Posted July 16, 2005 Well, -10 is a little low, but that won't cause a speed drop or reset off generally. Everything else looks good, 46 is good for the upstream. Sorry, I guess you'll have to wait for the tech. Quote Link to comment Share on other sites More sharing options...

dn0 Posted July 16, 2005 CID Share Posted July 16, 2005 Your upstream TX power is lower ( which means less attenuation, better ), and your receive looks much better. Across the board, it looks better. Did you re-configure any wiring, or did you just straight swap modems? Also, what plan do you have, 4000/512? Do you have a router, maybe? Your dl speeds look better, just not sure about the 1.5Mbps. Here's mine from Cox, for example - 4000/512 :::..

dn0 Posted July 16, 2005 CID Share Posted July 16, 2005 It does look like your router may be slowing you down a bit, or other traffic from another PC on the LAN. As for the receive level, the temperature has a large effect on the levels. My Rx is about 5dB higher at night; when the outside heats up during the day, it drops a few dB. That is normal, I am running between -3 and -8dB Rx, with no issues. Has your modem reset since you installed the new one? Quote Link to comment Share on other sites More sharing options...
