is there a program that can monitor either my modem or network as far as up and down time? i relocated to a new state and had charter come out and set everything up. was humming along fine until directv came out 4 days later. ever since then i've had random disconnects like a mother.

not saying they did anything, but i need some proof to show charter because of course every time i call in they say "well i see your modem is online".

does such a program exist so i can shove it in their face and get them out here to look at it?
 
pull up your modem status page and look for "t3" and "t4" timeouts. If you are getting them then your modem is dropping at least one channel.

Direct TCP access to remote RPC servers (port 135) is blocked.

This is probably for security reasons, as this protocol is generally not designed for use outside the local network.

Direct TCP connections to remote SMTP/SSL servers (port 465) succeed, but do not receive the expected content.

The client received an empty response instead of our normal banner. This suggests that a firewall, proxy, or filter initially allowed the connection and then terminated it, either because it did not understand our server's reply or decided to block the service.

DNS lookups of popular domains (?): Warning –

2 popular names have a significant anomaly. The ownership suggested by the reverse name lookup does not match our understanding of the original name. This could be caused by an error somewhere in the domain information, deliberate blocking or redirection of a site using DNS, or it could be that your ISP's DNS Server is acting as a DNS "Man-in-the-Middle".

We attempted to download HTTP content from the IP addresses that your ISP's DNS server returned to you for these names. Where the download succeeded, you can click on the IP address in the table below to download a compressed file containing an HTTP session transcript.

Note! The session content is potentially harmful to your computer when viewed in a browser, so use caution when examining it.
Name IP Address Reverse Name/SOA
www.citibank.com 192.193.103.222 citicorp.com.au
www.smithbarney.com 205.228.54.128 SOA: ns-ext1.ms.com
90 of 90 popular names were resolved successfully. Show all names.
24 popular names have a mild anomaly. The ownership suggested by the reverse name lookup does not match our understanding of the original name. The most likely cause is the site's use of a Content Delivery Network. Show all names.
3 popular names have a mild anomaly: we are unable to find a reverse name associated with the IP address provided by your ISP's DNS server. This is most likely due to a slow responding DNS server or misconfiguration on the part of the domain owner. Show all names.
DNS external proxy (?): OK +
DNS results wildcarding (?): Warning –

Your ISP's DNS server returns IP addresses even for domain names which should not resolve. Instead of an error, the DNS server returns an address of 198.105.251.24, which does not resolve. You can inspect the resulting HTML content here.

There are several possible explanations for this behavior. The most likely cause is that the ISP is attempting to profit from customer's typos by presenting advertisements in response to bad requests, but it could also be due to an error or misconfiguration in the DNS server.

The big problem with this behavior is that it can potentially break any network application which relies on DNS properly returning an error when a name does not exist.

The following lists your DNS server's behavior in more detail.

www.{random}.com is mapped to 198.105.251.24.
www.{random}.org is mapped to 198.105.251.24.
fubar.{random}.com is correctly reported as an error.
www.yahoo.cmo [sic] is mapped to 198.105.251.24.
nxdomain.{random}.netalyzr.icsi.berkeley.edu is correctly reported as an error.

you need to access the "DOCSIS LOG"

If it asks for a username / password use chtrtech / charter

also, your upstream power level is a bit high which could be causing your problems. Do you have any splitters in your setup? If so, you modem should be running off the first splitter in the system.
 
So you have Cable Internet, and DirecTV, right? You don't happen to have them both sharing the same coax system, right? If you are, that's probably your problem. What you need to do is trace your wiring and make certain that anything DirecTV is isolated from anything Charter.

No go on the username and pass.

And yeah this house has splitters 8 ways to Sunday around here. Its a rental so there's no telling what's been done in the past.

Not a clue what those guys have done with the wiring. But when I called charter they said they could see it dropping the same day it was installled. As of 8ish tonight I've dropped 43 times just today.

A charter engineer will be out tomorrow to take a look.

Sounds like the direct tv guy hijacked one of the charter outlets and either split it or used a diplexer on it.
