As an additional check you could try going direct to the cablemodem and see if that changes anything, but, as I said, your downstream SNR is marginal at 32.5dB. So I suspect you have a cabling or modem issue. But I'm far from a cable system expert, so I could well be wrong.

im on a diffrent internet connection right now. since mine is almost worthless. online video games are too laggy to even attempt to play. surfing the webs like dial up most of the time. and forget about watching youtube videos or streaming tv shows
EDIT

im in a different house so i cant really provide much more cuz that line test was in my msgs from last night and i could post it from this computer. Im thinking this is on comcasts side not mine. This has happened before and it lasted 3 weeks then cleared up on its on. I had all wires replaced and coax ran from the pole to my house. Router is a Belkin wireless N+ with the latest firmware. Modem Is the small ambit modem comcast provides sorry forgot name and cant check from here. No splitters at all since i only use internet now. Also does anyone think i could be getting my connection trottled by comcast? I dont think ive reached any kind of cap limit or close. I do play a bunch of Xbox live and i stream tv shows,movies, download songs.]]> http://www.dslreports.com/forum/Re-Speed-slow-internethigh-ping-23894956 Wed, 03 Mar 2010 17:13:34 EDT http://www.dslreports.com/forum/Speed-slow-internethigh-ping-23894932 http://www.dslreports.com/forum/Speed-slow-internethigh-ping-23894932 Wed, 03 Mar 2010 17:08:36 EDT
