11011100 Posted December 27, 2004 CID Share Posted December 27, 2004 I have had problems for around 7 weeks now with Comcast. So smuch so i am with the customer advocacy group and have had 4 diff techs come by the house. Everyone says the modem is fine with good signal and they dont know what the problem is. Can anyone here help?

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 Quote Link to comment Share on other sites More sharing options...
VanBuren Posted December 27, 2004 CID Share Posted December 27, 2004 hey 11011100 and welcome to the forum I dont know what those errors mean but, have you tried with another LAN cable from your modem? Or tried with another pc? Did the tech try your modem with a laptop? VanBuren Quote Link to comment Share on other sites More sharing options...

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

MICROWAVE Posted December 28, 2004 CID Share Posted December 28, 2004 Have you tried using WntIpcfg.exe,its part of tools if its installed on your computer, I have found it very useful in the past to release and renew my IP config....here is a pic on how it looks Microwave Quote Link to comment Share on other sites More sharing options...
11011100 Posted December 28, 2004 Author CID Share Posted December 28, 2004 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 diak Quote Link to comment Share on other sites More sharing options...
MICROWAVE Posted December 28, 2004 CID Share Posted December 28, 2004 11011100 , That tool is not just for that, it will do many things,some months back I was able to clear a similar problem using this, thats the only reason I mentioned it.....but anyway let us know what happens....OK? also do you have any logs to compare from a time when things were running good? when mine was acting strange I was able to clear by renewing everything until the next time it happened, after I got a new IP addy it has never happened again.....go figure.....of course I have been told that the two are not related but, I have had engineers tell me for years that what was happening with something was not possible.....lol ,,,,,,,,,to bad the equipment didn't know that!!!!!

The Reverend Posted December 28, 2004 CID Share Posted December 28, 2004 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."

fred Posted December 28, 2004 CID Share Posted December 28, 2004 there are several things that happen with dhcp 1. authorization 2. hand shake and then you sync up. as mentioned before the isp is definetly at fault here be cause you can't sync up and in xdsl you have 3 or 4 different types of protocall 1.ppp 2.pppoe 3.ppoe ras so on and so on. what I hear here is no upload so your isp is at fault they need to re check the distance of your central office sounds to me like your on the fringe of dsl distance acceptance Quote Link to comment Share on other sites More sharing options...

jim2006 Posted December 28, 2004 CID Share Posted December 28, 2004 I don't know if cable works the same as dsl but I had about the same problem I payed for 1.5mbs/128kbsup and I was getting around 340kbs up and down.Sometime more but not much!! So I called them and they told me there was no problem on there side!! I pretty much said bull shit but not to them at first!!! So I tweaked no help got help from vaburen still nothing!!! So I kept calling them day after day till for about 3 months!!! Until on day they told me there was a problem with my line ( finally the truth). They said the line test shows I am to far away to get more than that!!! He said that the only way to fix it would be to move my line to a remote station.(Which they said tthey did before but didn't) So anyway they did and no it is faster!!!!! But my point is maybe you are routed to far away too!!!!!! I think that is what these mean: Sun Dec 26 05:44:02 2004 Critical (3) Received Response to Broadcast Maintenance Request, But no Un...

Marcin541 Posted December 28, 2004 CID Share Posted December 28, 2004 Doing the iprelease thing might help, if you have a static IP. I dont think it will work with dynamic. Quote Link to comment Share on other sites More sharing options...
MICROWAVE Posted December 28, 2004 CID Share Posted December 28, 2004 Doing the iprelease thing might help, if you have a static IP. I dont think it will work with dynamic. 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 Microwave Quote Link to comment Share on other sites More sharing options...

resopalrabotnick Posted January 8, 2005 CID Share Posted January 8, 2005 the faq clearly states that the link of the entire hosting site is 20 gig split among a host of providers, while the box this test is on itself is linked to that with a 100mbit link. :haha: rtfm! :haha: Quote Link to comment Share on other sites More sharing options...
