Those same critical errors are ALWAYS there and precipitate my connection loss (intermittent), but no one knows what they mean???!!!!

I have no upload AT ALL..it's even hard for me to log into this site...and any upload speed tests do not work at all!!

I will leave Comcast and go to DSL in my area if this continues. Would rather have lower consistent speeds than this.

Thanks
diak

it's been happening for the last 7 weeks...and a week ago i got a brand new comp...so i ruled out probs with my computer

i don't use a router atm so there is no issues there...and i have 2 cables....tried both   

thanks for the welcome..i like the new design CA3LE

I'm  not an expert but it looks like you for some reason can't get an IP address. The ip address is recieved through a DHCP server. When you got your new computer did you use the same network card? If not, call Comcast and they should give you a web address to "activate" your computer. This  let's them know your  nic's mac address so they know you're only using 1 ip address on their network.

I'm just guessing though so don't hold me to it.

nah i have an ip address...

just figured maybe somene knew modem event logs here...i know mine are bad....and prob you can see that too (critical being the control factor =P)

thanks anyways

Yeah, you have an IP address, but since nothing on their end is working, (meaning their DHCP is NOT handing you your IP#), the IP# you are looking at "in" your PC isn't correct, or isn't "linked up."  The event log pretty much states that 'loud & clear'.  The problem is on THEIR end, not yours (unless the modem needs a reset, which they can do easily enough), ...most likely their MDM can't "see" you for whatever reason ...it's a 'bug' of sorts.  Road Runner did that with me once, and a new Static IP resolved the issue ...in fact, they just redid my entire account "from scratch."

Or ...what kind of shape is your TCP/IP stack in?  There are 'bugs' that'll bring on these type of probs too.

At the moment I can't remember the command line parameters for reseting it (your TCP/IP) ...but I'm sure CA3BLE or MICROWAVE have it handy. 

Cheers!

As they said ^  its on the isp's end, but at least try to force your way before kicking the S#!t out of them

In the command prompt ( start > run> cmd> ) type ipconfig  you will now see your ip, and subnet blah blah etc. then type iprelease , SHUT DOWN your computer, then unplug the cable modem for 60 seconds. then plugin your modem, then the computer (deffinatly in that order)  then, go to the command prompt once more and type iprenew . that should *try*to refresh the ipaddress, or atleast try to gain network recognition.

cable doesnt have a distance factor. dsl does :s

  Yeah I agree but what it does do is cause a different kind of reset to the modem and the network takes another look at your connection and decides if it needs to do something different or leave things the same. its funny because I have had this discussion with ppl b4 and although computers are different than phone lines I have seen it hundreds of times where there is a problem on a line and just by testing and not finding anything the problem mysteriously disappears., another for instance the last time I called my ISP to ask a quesation,...he said your modem is off line so your not really on the internet..... :ha ha: REALLY well I dont think my computer knows that because I just sent myself an email and I'm cruising all over the place....lol....but this is the kind of stuff I love ....when ALL the equipment either says everything is fine or everything is broken, and in reality the opposite is true.........Thats why I love this shiz, and things that were talked about years ago as something that technology may do someday , all that has happened and a lot more than was ever expected.......... I asked a instructor one time long before computers about the * and # sign on phones, and I was told that someday in the future that these would be used for features but probably not in our lifetime, I then asked what happens when we run out of phone numbers? and I was told again not in our lifetime  all that and much more has now happened, thats why its such an exciting time in the world of computers ....for me anyway!!! Everything keeps changing so fast and so quickly its amazing, although I guess for many ppl that grew up with this stuff and just take it for granted  its no big deal   It hasn't really been that long ago where ppl only had 4 or 5 local  T.V. stations and they went dark and played Taps at around midnite....that really sucked for someone like me that stays up most of the nite.....all that was left was late nite radio......LOL....anyway sorry ....blah, blah, blah
