As of Win2K/XP, there is an adjustment for the Send Window, though it has proven to be ineffective/useless.
thanks for making this more simple for me to understand. I appreciate your clear answers. I'm sort of a techie, and I get lost in my own shorts with detail. I need clarity and your site has provided that for me. Thank you and Happy New Year! Leonard
For example, if your advertised download speed is 1500kbps (1.5Mb), getting around 1250kbps would be very good.
Remember that Windows download window reads in KiloBytes per second, not kilobits. There are 8 bits per byte. So if your think you're slower than you should be, do the math before going nuts.
Note: Keep in mind that upload is non-adjustable, but may go up once your system is optimized.
1 bit (b) (0 or 1) = one binary digit
1 kilobit ( kb) = 1,000 bits
1 Megabit (Mb) = 1,000,000 bits
1 Gigabit (Gb) = 1,000,000,000 bits
To find your theoretical download speed for your line, divide your advertised speed by 8: 1500kbps / 8 = 187.5 KB/s
Or by 10 to include overhead: 1500kbps / 10 = 150 KB/s
Several of these "speed patches" add superfluous RWIN settings that do nothing other than cause slowing due to packet loss. Don't believe the hype about huge RWIN settings. RWIN simply doesn't work that way.
•Clear your Browser's Cache and Temporary Internet Files.
•If you're using any proxy server, disable it here.
•Power-cycle your modem/router, directions here.
•Your modem, router or cables are too close to a device that
emits EMI/RFI and need to be moved.
•Check that your NIC (Network Interface Card) drivers are up
to date from the manufacturer.
•Check that your cables are plugged in tight. If you have some
spare ones, try another cable or swap them around.
•For DSL connections, one or more filters may have gone bad
and need to be replaced. For cable connections, a splitter may
have gone bad.
•For DSL connections, check to be sure all phones or devices
hooked to the phone lines are filtered, including external fax
machines, Satellite Dish receiver, TiVo and ReplayTV DVRs, Analog
MODEMs (internal or external), PPV cable boxes, cordless phones,
wall mount kitchen phones, etc. You should also not exceed 6
filters in the house, and if you do, you will need a whole house
splitter and a home run installed (either do-it-yourself or
professional installation). [Thanks goes to Doctor Olds for this tip.]
•For DSL connections, your inside phone wiring on your DSL line may be bad.
Try checking your sync and speed at the NID or INI.
While the above is not an exhaustive list, it provides a good place to start.
got feedback?here to find some.
If you're unsure what speed test is closest to you, look at the map of Speakeasy.net speed tests.

got feedback?16meg or 64meg, for download speed tests. Then, upload that file to the webspace provided by your ISP or free server such as Yahoo to test your upload speed.
When it's about 40% done, take note of the KB/s and cancel the download. Multiply the KB/s you got by 8.192 to determine your speed in kbps. Example: 56.2KB/s * 8.192 = 460kbps.
To measure your download and upload speed, you may use a third-party throughput meter. Here are a couple popular free meters:
Paragraph 2 should say "Multiply the KB/s you got by 8 to determine...". It should say multiply by 8. Bits and bytes are integers. There is no such thing as a fractional bit or byte.
TestMySpeed.com, but they are not like the Speakeasy java tests. They might show different results because of the distance and/or type of content being used to test.
A symmetrical connection (where the downstream and upstream are the same speed) is ideal for business use. If one person on the network on an asymmetrical connection uploads a large file, then everyone will slow down.
A 10Mbps or a 100Mbps NIC (Network Interface Card) will not make a noticeable difference in your speeds, because this is the NIC's speed and not the speed of your Internet connection.
However, if your line is faster than 10Mbps (very rare), then you will need a 100Mbps NIC.
The answer in 2013, is possibly! If you have a 10Mb nic, definitely upgrade. 10+mb is the new norm, and 100mb is even becoming common.
here first to make sure the problem is not due to a distant line problem, such as a bad router at one or more hops. Then post your line quality test in the DSLR Tools forum if you want help diagnosing the problem. If your line is clean and you still have speed problems, then try tweaking.
Windows ME/9x: Right click "My computer" > "Properties" > "Device Manager" > Drop down the "Network Card" in the list, go to its properties, and then to advanced. Set it to "10mbit Half."
Windows XP/2k: "Start" > "Control Panel" > "System" > "Hardware" > "Device Manager" > Drop down the "Network Card" in the list, go to its properties, and then to advanced. Set it to "10mbit Half."
If this does not help, try "Auto" and experiment from there.
"This problem can occur if the NDIS intermediate driver code is preempted by the operating system when it is not safe to do so. As a result, a 'race' or 'deadlock' condition may occur, causing the operating system to hang."

The internal circuits of personal computers generate RF fields. Also, cathode ray tube (CRT) displays generate EM energy over a wide band of frequencies, monitors in other words. These emissions can interfere with the performance of sensitive devices (such as your modem) nearby. If you have a sensitive device of any kind and use it at the same time as you operate your personal computer, you will probably hear RF noise in the receiver that originates in the PC system.
Just like the other guy's I would sure like to know the range, my Docsis 3 sit's right on top of my Telephone Modem and I will be surprised if I can get ahold of anybody at Comcast that TRULY KNOW"S the answer!
If you were to download off of someone with a 256kbps upload, then they can send you files at 32KB/s, at most, if you are the only person downloading -- even if you are using a T1. If multiple people are downloading off of that person, the speed divides so everyone can get an equal share. Thus, it slows down more.
Don't forget, it's important to make sure your computer's optimized for speed. Be sure to check out DSLR/BBR Tweak Tools for tools to help you tweak your speeds. Also, be sure to check out the Tweaks forum for more useful information!

Two ways to do this.
1. Go to your NICs/dial-up adapters manufacturer and get updated drivers there.
2. Right click on My Computer, and then choose Properties/Device Manager. Click on the "+" sign next to Network Adapters. Double click on the adapter you use to connect with, then choose Driver/Update Driver/Next. Choose "Search for a better driver." Then, only enter a check for "Microsoft Windows Updates." Click Next. Follow the directions from there (easy). If new drivers are found, you will be informed. If not, there's nothing lost.
got feedback?thread. This program only works on Windows NT, 2000 and XP Home/Pro. If run on another OS, it may simply refuse to work.
