Charter Cable Internet Signal Strength - Too Low?

Post by Apoptosis »

My Charter Internet Cable Connection has been hit or miss this past week with half the time I'm unable to connect to the internet. I've removed everything except for a Linksys Broadband Router and the Webstar Cable Modem and am still having problems. Gave Charter a call and they want to send a Tech out to look at the line signal strength from my house in a week... Who wants to wait a damn week...

I know some of our members work, or have worked in the ISP industry, so can anyone make sense of my downstream and upstream stats from the cable modem:

The signal to noise ratio is VERY good!

The higher the Db the better
As a rough guide (based on downstream value)...
<6dB is bad and will experience no sync or intermittent sync problems
7dB-10dB is fair but does not leave much room for variances in conditions
11dB-20dB is good with little or no sync problems
20dB-28dB is excellent
>29dB is outstanding

Is the webstar modem loosing sync or is the connection getting very slow?
Goto the config page on the Linksys router (Normally it's 192.168.1.1)
http://screenshots.modemhelp.net/screen ... uter.shtml
Then click on "Status" and see if there's an internet IP address.
IF not, then there's an authentication issue (username/password issue) --> This normally cannot be resolved by a tech via a site visit. This will have to be fixed in via a port config, user profile config or it can be a RADIUS issue. (all this is inside the ISP network)

IF you're getting slow speeds, then it looks like you're either suffering from congestion or throttling.

Have you tried to re-enter your username and password on the router?

Check out pingplotter when I try to get to the internet as I'm getting serious packet loss. I'm on Cable internet, so I don't have a user/pass. I did when I had ADSL and a PPPoE connection. Also I can't get to the status tab as I'm not authorized.

Looks like the packet loss is on the ISP's network.
Can you do "ipconfig /all" and do a continuous ping to your router & local host?

start / run - type CMD then ping -t 192.168.1.1 & ping -t 127.0.0.1

If you get packet loss (timed out) or times over ~3ms then the problem is your end.
It's possible a software firewall etc. is corrupting data, specifically the the ip headers effecting the TTL (Time to live) --> This is unlikely but I can't think of anything else on your end that could cause this.

Just to be sure, you're not using wireless are you? I know you have lan ports in the house, but if you are using wifi then try via ethernet.

I'm certain the problem is with the Charter LAN though!

Yea, I was gonna say, your stuff looks just fine. Good thing you found out quick that it's just Charter's lame ass network. You can tell right when you hit Charter, your ping spikes hard. I don't really have too many problems w/ TWC, but I always had problems when I had Charter.
