[Cable] I need help to tweak my settings, or check them at leastOK I just switched to optonline and have a few questions. Please dont make fun of me if they are stupid.
1. My advertised speed is 15/2 Mbps. Is this what I should be getting from my wireless cards? And my hard wired computer?
It would seem that if I get 15mbps down then a 54 mbps G card should be good enough right? Why go to N wirless? Is it just for network speeds from one computer to another?
2. I ran some speed tests at like speed.net. It shows close to my advertised speeds. But there are other sites that show me at less then half of that speed. Are they the real sites that test the computers and not the modems?
3. I downloaded and used that app from speed guide.net. I have no clue what I am doing.
4. Can someone help me? Could you tell me where to go and what to run to check my settings for me. I will post whatever info from any test you tell me.
5. I dont know if I am even on the right forum. I tried several fourms but people are not answering my post.
Win XP Arris tm 802 router Netgear wnr 2000 v.3 wirless router dell with 1500 draft N dell 3000 with ethernet connection through lan card.
Thanks

Re: [Cable] I need help to tweak my settings, or check them at l• Yes, I see that you posted in the OOL forum. It is not good to post the same thing in different forums. So you should pick one and stay with that one. • Above what advice you have already received, I 'll a few other one. • That Speedguide tweaker has an undo in it. Undo the changes before going to the next step. • This is the Tweak Test that you posted. » /tweak ··· a=normal• Try this: Download DrTcpSet Tcp Receive Window to 128480Set Selective Acks, Path MTU Discovery, Black Hole Detection to Default. Leave Max Duplicate Acks and TTL BlankUsing the drop-down menu in The Doctor set your NICs (Ethernet adapters) MTU to 1500. Save/Exit DrTcpRebootRerun the Tweak TestRun Two Speed Tests from the two DIFFERENT cities nearest to you that are listed here: Speakeasy POPsAlso, test here » ftp:// ftp1.optonline.net/test512Note your transfer rate after about 30 seconds. Then cancel the download.Post the URL for the New Tweak Test. For the TWO Speakeasy Tests, Copy and Paste the speed results from those tests and note the speed from the FTP download test. • Make sure that your router has the MTU set to 1500 or Auto. • For the wireless boxes, do the above for them. |

OK should I undo what I did at speed guide then post a new tweak test>
Also my MTU in my netgear wireless router I can set. The MTU is 1500. The arris cable modem I dont think I can change the settings. I have no log in. They gave me no address to check.
Let me know and I will start.
All I changed at speedguide was,
tcp to 513920 IE opt 10/20 tos value 80 lan buffer size 32768
Also do I do the same settings on my wirless computers as well as the one that is hard wired?
And thanks so far.
Again let me know before I start. Possibly you want speed tests from the config I have now.

• The MODEM does not have any setting for MTU.
• Yes, all boxes.
• You are ready to go. |

I dont get what you are telling me to do.
Should I do what you stated above? Roll back to original?
Or run all tests with my current settings?
I am stupid and need it laid out step by step.

Very good, Mike.
I assume that is the wired box, correct?
Do just what you did above, but set the RWIN to 160600.
Tweak and post the results. |

No this is the wirless notebook with a dell 1500 draft N card.
I assume one I get one computer down for optimal speed all the other computers would be set the same?
OK I am going to change the settings to what you specify I post results in a few minutes.

How can I decipher the tweak data so I possibly can modify myself? Can I raise the tcp more?

That looks pretty go so far. There is a mismatch in the MTUs. Look at the tweak test. Both MTUs should be 1500.
In The Doctor,does the MTU show 1500? If not select you adapter from the drop down list, and apply the settings and repost the results.
You can also check the NIC and see if there is a setting for the MTU.
After checking the above, do the same for the next box. Also, make sure the other boxes are powered off when doing the speed tests.
Leave the RWIN where it is now. A higher RWIN does not always reflect to better speeds unless the RWIN is way too low. You want the lowest RWIN that gives you the most consistent speed without errors. |

I see the MTU difference.
The nic cards were all changed to 1500 in the dr tcp.
This computer is wireless. I looked in the advance section of the card and see nothing to change mtu.
the wireless router is set to 1500.
All my computers show that when I do the tweak test.
I wonder if its the arris router. I dont know how to check or change the settings in there. The cable company did not give me info.

Bump.
I dont think I can change the MTU in the router. I found the link to look in the router but there are no changable setting.
So the MTU comes from OOL i guess pre set on the Arris modes.
So since my tweak test show a 1470 mtu should I change the MTU on all the computers with dr tcp to 1470?
And I was thinking I could call the cable company and ask, but I was reading about my sons X box not likeing 1500 MTU. They suggest a min of 1394 or something.
I wonder if this is why the cable company sets the mtu to 1470... for gaming????
OK so all in all should I change my computers to match the router MTU???????? |

The mismatch on the MTUs is not a deal breaker. The two are close enough and it should not hamper you speeds.
Do not change the MTU. Leave it at 1500.
Now, go back to tweaking your other boxes. |

I been reading a bit and it seems the 1470 is due to some header?
Is this correct? I did read the header uses 28 so the mtu should really say 1472.
I may be talking out my arse though.

The header is the MTU - MSS. The MSS for a MTU of 1500 is 1460. (Header is 40 bytes) Your MSS requested is 1460. Look at your Tweak Test above. The 1470 is the MTU and includes the header. You can find your MTU here: » Tweaking FAQ » Max MTU: How do I find mine? |
