the router you posted is fine, the modem you linked to however, is a dial up modem, not a cable modem, its just an external dial up modem, so it kinda looks like most cable modems.

[JohnWill]

Yep, clearly that dial-up modem isn't going to cut it! What you want is a DOCSIS 2.0 or better compliant modem for cable Internet service.

Here's an Amazon DOCSIS MODEM search for new and used ones. Obviously, this is an example, there are many other places to buy them.

Ok so im good on the router...

For the modem since Charter is my ISP do you think I could get a replacement modem etc?

And here is a link that I think is the right type of modem. I forgot to look at the device type for that other one...

[JohnWill]

If Charter has supplied the current modem, you can get one from them, but it's normally a rental. If you plan on keeping the service for a long time, it's more cost effective to buy a modem.

The latest link is the proper modem for your service.

I havn't been able to buy a new router/modem yet (for misc. reasons)

However I did do a speed test on the Charter website. Actually multiple tests. They are just upload and download speeds. All test were done within seconds of each other, and even faster consecutiveness when the speeds where peaking out.

*Please look over these results and analyze them!

I'm just curious if there may be any problems other than the modem.

[JohnWill]

Well, it's either the modem or the ISP, but it's hard to know. The real test is to substitute a known good modem.

[Neo V]

Yeah, I'm going to bring my current modem to my school. I'm going to test it out there with my teacher of my CET class. I'll also check if I can get a friend of mine to let me borrow his modem for a while.(same person/home that i brought my laptop too. I used his modem and earlier and it worked great.)

[JohnWill]

Note that for cable service, you'll have to contact the cable company and get them to change the MAC address of the allowed modem in their database or you won't be able to connect at all. Most DOCSIS modems on cable systems are controlled by the MAC address of the modem.

[Neo V]

Ok, sorry its been a long while since my last post. (I hope no one thought this was dead thread...)

Anyway, I went to my friends house again,(Same person from the previos posts,)

I did some tests. I brought my actual modem over their. He does not have a router.

Here are his computer tech specs(to the best of my knowledge...)

eMachines computer*
1.7GB~ ishy RAM
Windows Vista OS
128GB ish hardrive.

Ok, I also brought my lap top.

Too the results!

When I connected my modem to his cable, and connected the modem directly to his computer, there was "no connectivity problems WHATSOEVER!!".

When I connected my modem to my computer at his cable connection the same old lamo problem happens.

When I connect my computer to his modem, It works great and with perfect connectivity, just like last time I went to his house.

And of course, his modem to his computer works perfectly fine.



Furthermore, the only test that I have not done to determine the problem is to bring his modem to my house and test connectivy results on my desktop and laptop.

In my opinion the problem is between my laptop( and my desktop) and my modem. They seem to have some issues.

Hope this helps in determining the problem!

Thanx for all the help.

[JohnWill]

Sounds like time for a new modem.

[Neo V]

Ok, We met up with charter and got a technician to come over to our house to look at the problem. They were unable to accurately determine the problem. But the guy said that it was not the cable. He also suggested in switching out the modem we had with a new one. So he went to his truck, and got one and hooked it up and set the mac address etc. He also put this modem on a watchlist until the 25th of July. However im still skeptical, even though for the first 2-3 hours of being hooked up it worked great for web browsing and googel earth. Additionally, it also works better in general. But its still not so, streamy after 3 hours ish.

[Neo V]

Addition to my above post*

Yes, it seems like switching out my old modem to this new modem did not "entirely fix" the problem. However it does still work better all around then the other one, but the problem persists. Now im out of ideas.

-its not charter(at least i dont think so)
-its not the cable
-its not the modem
-its not the computer
-its not the network/internet configuration(i dont see how it could be anymore because the same configuration settings work at my friends internet
-its not the servers im connecting to
-its not my firewall
-its not the anitvirus
-and I don't have a virus because McAfee does a scan everyday.

I am completly stumped. Even the technician did not know what could be wrong. I showed him a speed test from charter that said 0kbps download and upload speeds, and he said that was impossible(which does make since, because if the speed is 0, then there is no connectivity...)

I have no idea what the problem could be.

[JohnWill]

I think that Charter is lying myself. What is the exact make/model of that modem?



Connect a machine directly to the modem with a wired connection and do the following tests.


Register at DSLReports and run their Line Quality Tests. It's best to run this test with a direct wired connection to eliminate any wireless issues from the results. It's useful many times to run this test several times, and we'd like to see each of the results. Post the results link from the top of the test display page for each test run here.

The link to post is near the top of the page and looks like:

If you wish to post this result to a forum, please copy/paste this URL
http://www.dslreports.com/linequality/nil/2357195 <- sample only, yours will obviously be different!
and your IP will be disguised.

Copy/paste that link here.

Note: You will have to enable PING (ICMP) request response either in your router (if you have one), or in your computer's firewall for direct modem connections. This is very important to get the most important part of the test to run.


DSLReports

Here's also the Line Quality Tests FAQ to help you understand the results. This will answer some questions about the line quality display.

Ok, its been a while since my last post again***

Today is the last day that Charter put this modem on watch. From what I have figured out, both modems that i used are not bad. Hopefully charter can make somthing of what they see on the information they got.

And for those line quality tests, it keeps saying that the target IP does not respond,(Since when did you have to pay for the line quality test? I only got to do 3 by the way,) I seem to have trouble trying to figure out my real "Real" IP address.

Also, The make and model of the modem... At this link it shows why kind of modems that charter uses (or so i believe). The modem that i used before charter switched them was the scientific atlanta DPC2100. The one that im using now and the one the charter technician provided after switching is the Ambit U10C018.

http://www.charter.com/customers/Sup...abContent_EUGD



This may sound pointless to say, but could it be possible that the modems that i have been using are incompatible "tech spec. wise" with the computers that we purchased? I highly doubt it but Im running out of possible troubleshooting factors, they have all been eliminated.

[Neo V]

This seems to be a problem that i just now recently been noticing, it seems that every 30mins to 2hrs there are random disconnections from the internet. Not the same as the previous problems. I am sure that i did have this problem before, and with both modems as well. I have

This is the previous problem I said at the beginning of this topic. When i try to browse a webpage, over 50% of the time i get timeout or broken link errors. Online gaming is laggy, fails to establish a connection, or cannot maintain a connection, and dissconnects me from the server(s) often. Downloading and Uploading random stop and pause multiple times, I could be downloading a file at around 500 kbps and then it will stop/pause downloading and still say the same speed but there is no down or upstream activity(except for a blinking send light on the modem, which i believe to be my computer trying to ping the server to continue the download) All of this happens while it says that I have internet connectivity.

And now this problem that i dont know how i did not notice. The connectivity will randomly lose connection to the internet. At the network and sharing center, when this happens, it looks like what happens when the modem is reset. It loses connectivity briefly(30sec-3mins) and then says identifying, then re-establishes the connection.

This is the most exotic computer/network related problem I have ever seen.
