Changed those 2 settings. Below is new analyzer report + tracert report.

Does anything else need to be changed?

Just updated my cable modem today to a Motorola SB6120 and I re-ran the analyzer test and it said that the "check bit" is incorrect. Can someone please check it out and tell me what changes in TCPOptimizer I need to make. Thanks.

Thanks for your input akbarri. I've received 3 different settings from 3 different members here and I'm unsure which one is recommended for my ISP and speed.

Below is my analyzer with your values. Please tell me if it's correct. Thx

Trogers....leaving the TCP Receive Window BLANK seems to cause slower loading pages. Did you have a chance to check out the latest TCP analyzer I posted w/ your settings (post #9)?

Post a new TCP Analyzer report after rebooting the comp to see if MTU goes up to 1500.

Didn't my last TCP Analyzer results show the MTU already @ 1500? Unless I'm seeing and reading something different here.

Also I didn't see the value for "LAN Request Buffer Size" in your settings above.......I ...

I was reading elsewhere that the MTU value for cable internet should be 1500.

Any truth to this?

Hi.

I'm switching from AT&T DSL service (3 Mbps) to Charter High Speed Internet service (10 Mbps) tomorrow and I was wondering which program [TCPOptimizer or Cable Nut] works better with Charter HSI?

Thanks.

Hi trogers. Thanks for your prompt reply. They only change I had to make from my current TCPoptimizer settings and yours listed above is the TCP Receive Window . It seems that page loading is a little "choppier" than before. Test results below.

Is this normal down and up speeds for this type of DSL connection?

Also I need to update/tweak my TCPOptimizer settings (previous ...

MakaveLLi

Thanks for clearing that up. Although I've noticed that Cablenut has way more settings to "tweak" than TCPOptimizer.

How does that program work compared to TCPOptimizer?

MakaveLLi

Thaks for your reply optikal. Unfortunately my pc is a dinosaur and it doesn't have a slot for network cards (only video cards). So I'm pretty much stuck with the built-in NIC.

So 'auto-negotiation' and '100m/full' deliver the SAME results?

MakaveLLi

Is it better to use CABLENUT to configure your registry settings or TCPOPTIMIZER?

My settings/values were adjusted using TCPOptimizer. Are there any advantages using Cablenut?

Just wondering. Thanks.

MakaveLLi

My guess is that MTU is limited by your modem & router !

Netgear support told me that the 40 byte difference is probably header data.

Also when I run the analyzer tests, I get the following message under MTU:

"MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for ...

I just upgraded my DSL from 1.5 Mb/s to 3.0 Mb/s (to be completed in a couple of days).

Page rendering seems a little better than before, but maybe it's the "placebo effect" on my end, LOL.

MakaveLLi

You're using RWIN of 96096.... Just as it says... the RWIN (Max TCP Receive Window) is optimal when multiple of MSS. However, TCP headers support a single 16 bit (up to 65535) value (refered to as Unscaled RWIN by the Analyzer), and the way TCP uses larger RWIN is by multiplying the unscaled RWIN ...
