u're just a dumbass who can't read. he gave u the site to guide u abt tweaking your connection. dun blame pp if u dun hav the intellect to click on the word "TWEAK" to find out more. stupid idiot. fucking SOB.

this is what that website says u dumbass,

Tweaking your PC:

First check the DSLReports Tweak Test.

The Windows default TCP/IP settings can slow down the speed of a broadband connection. It may be necessary to tweak your settings to get optimal speeds.

Download DrTCP.

As a starting place, set your TCP receive window to 64240. Choose your network card in the adapter settings dropdown box and set the MaxMTU for your network card to 1500.

Apply, exit and reboot.

Re-run the speed tests on the "Speeds" page. There is a good chance you will see a HUGE jump in speed from the default windows settings.

Those settings are the best for the majority of people on OOL, but not for everyone. To try to tweak further, either read the Tweak forum FAQ and/or post for help in the Tweaks or Optimum Online forums. You probably will only see minor jumps in speed from here on out. Some people suggest you make keep your RWIN a multiple of 1460. I'm not sure if that actually helps or not, but it can't hurt.

If you decide to use an RWIN>65535 and use Win95/Win98/98SE, you need to install the Microsoft vtcp.386 update found here: vtcp.386 update for Win98/98SE vtcp.386 update for Win95

In addition, for an RWIN>65535 to be recognized, you need to turn on Windows Scaling using DrTCP or another utility.

You also might want to check for updated drivers for your NIC. In some cases, this has resulted in a speed change.

Note: Changes only are effective after a system reboot.

MAC owners might want to read here for more.

Testing for Packet Loss:

Find out your default gateway by going to start-->run-->winipcfg and selecting your network card in the dropdown box.

Open up a dos box.

Let's say your default gateway is 24.188.240.1

Type: ping 24.188.240.1 -t

Let the test run for a minute or two then hit ctrl-C to end.

If there is more than 2% packet loss, you probably have a serious problem that needs to be investigated.

If you do have packet loss, try to re-run the test a few times to see if it was just some sort of anomaly or if it's definitive.

Testing Modem Signal Levels:

3Com Sharkfin Older Firmware: http://149.112.50.65 Newer Firmware: http://192.168.100.1

Motorola SB3100 and SB4100: http://192.168.100.1

Terayon Terajet 110: Doesn't have this feature 3Com CMX: Doesn't have this feature Other modems: ???

They should be:

Receive: -15dBmV to +15dBmV Transmit: +34dBmV to +51dBmV Carrier/Noise Ratio: >30dB

The closer to the center of the spec, the better. As you get closer to the edge of the spec, you might start to see some connectivity problems.

Note: Signal strength does not really affect speed. So as long as you aren't getting disconnects/pauses/packet loss, you probably are ok, even if you are nearer the edge of the spec.

For poor levels:

Take a look at how your connection is set up.

Are you using multiple splitters?

If so, try to get the modem on the first 2:1 splitter.

If you have a 3:1 splitter, make sure you put the modem on one of the 2 splits that have a lower db loss (the db loss for each leg of the splitter will be printed on the splitter itself).

In general, it's best to split the cable only once before it hits the cable modem.

Also, possibly try replacing the splitter, maybe replace some of the cabling, tighten all your connectors, etc and then re-check your levels.

If all that doesn't get you into a good range, it might be time for a service call.

regarding modem tweaking.....cable modems are provisioned to the networks that thier on whether its controlled by a cmts or ubr. u can tweak the modem but it probably won't work depending who u have for an isp. most isp's will band u for abuse if caught flashing the bios of a cable modem to improve performance whether u rent it or own it. ubr's and cmts's constanty send snmp queries to the modem and can easily spot and flag a tweaked modem. so be careful of what u do!
