Known issue with several cable systems including comcast, where I work.
The modem is docsis 1.0, you need 1.1/2.0 IIRC.

PS Charter is slowly selling off their footprints, so maybe you'll get a new provider soon. :)

with comcast, and I assume charter, you can purchase your own modem and get what ...

Your DSLReports line quality test shows packet loss on your end. 7% for east coast, 100% for west. This is going to effect your speed, no matter what you or the ISP changes software wise. You need to determine the cause of this. The hops along the way do not matter, what ultimately matters is the ...

My computer is clean of spyware, I run spybot and another program for that. I have AVG as well. My provider is Nehp.net. I have DSL.

All servers are about the same, I tried many of them. I get about 10-20 ping difference in most. Not enough to switch from my main server.

Took my dad's truck for a spin and it sure seems to have some loss of acceleration and it's only around 130,000 km. I'm wondering if there's a problem somewhere like bad intake sensors or something.

Basically what I notice is unless you really baby it with slow acceleration the engine kind of ...

I play World of Warcraft.
My ping was 80-200ms in game. Last five days or so, it's went up to 500ms+

I contacted my ISP provider, they said it looked good on their end.

I personally have had no bad experiences when changing TCP settings, but there were some cases from other members who had, usually due to using the wrong MTU value or that their ISP does not accept the tweak value for Default ToS value.

But in many cases, members found they have had no improvement ...

Hi, I am new here, i just recently have been having slow cable speeds.. I am an on-line gamer, that depends on fast internet speeds.

They used some kind of signal analyzer at the DMARC and then again on the wire going into my DSL Model and they saw many more errors at the DSL modem. At the DMARC the signal looked very good. One thing they found was that I had just a Y and a filter (rather than a splitter) at the DSL modem ...

Thanks

While 9.8 is technically out of spec for an install its fine for the modem, and all he needs is a 3db attenuator on the back of it to put you at 6.8 and 49 so I'm not sure what he was trying to say...

Hi all, I'm a total newbie to broadband hardware. So thanks in advance!

Try the following with TCP Optimizer:

I have some questions for you trodgers.

Have you ever had bad TCP/IP settings cause latency? I ask because my experience with tweaking TCP settings has been you might get a little more throughput but thats about it, and that it never actually fixes/causes ...

Your PCs are failing to obtain an IP address from your DHCP service...which is your routers internal interface. The issue is either your router, and/or your computers.

I suspect this is correct, but try bypassing the router to test it anyway. Also check your cables they should SNAP into all ...

Helter, I'm sorry if I mislead you, but there is packet loss whether we route through the router or straight to the Time Warner Cable modem.

Jasonb31, I'll run that test tonight and post my results.

OK, so you lose packets going straight to the modem.

My ISP said they have narrowed down all the errors to 1 link and they are gonna upgrade it today. My question is: What do they mean by link?

It's not normal cable speak. It might be a splice in the higher up cable lines feeder, hard line, etc... or maybe an extending amplifier or bridger, hard to ...

So you have time warner cable, which comes in tow modem that has been swapped it then comes into a router which you have connected by Ethernet cables to the modem and to the two PC's. Without the router, there is no packet loss, with it there is.

This leaves

the ethernet cables not used with the ...

Hey - just a quick question.

My verizon service has set me up behind one of their NAT routers...

Depends on what your Verison speed is [FiOS or DSL?], but most likely not. The worst router will have 10 MB ports ...

Actually it can, he really means firmware and not modem config file, there is a comcast version of the dcm 202's regular firmware, basically it seems to just cripple the modem, from what I've read once you swtich to the comcast firmware theres no reverting back to another as it disables the telnet ...
