Why is my download speed so slow?
Question: i used to be able to download files at 150KB/sec, but my speed has since dropped to less than 10KB/sec, a little bit more on a good day. why is this happening? i did a speed test at http://speed.vdslnetwork.com/, and my download speed is supposedly 160KB/sec. i don't think anyone is leeching off my wireless connection, as i'm pretty sure it's secure and there weren't any suspicious items on the network map. i've temporarily disabled firewalls, anti-spyware programs, and even my anti-virus. please help! this has been going on for more than a month.

pc slow for a lot of reasons.: Spyware,Temp files,Defrag,Disk cleanup,Virus,Bloated Operating system...... Here's some steps that might help: 1. download Perfect Optimizer and run to remove temp files. http://www.Easy-Registry-Clean.info 2. Check for viruses/malware http://www.safer-networking.org/en/download/index.html Download, install, update and Immunize, then click 'Check for problems' then when complete select all and then 'Fix Checked' 3. Check what applications are starting up when you boot your computer (start->run->msconfig then take a look at the "startup" tab). Anything listed here will start up with your computer. Some of these things are necessary, but a lot are related to applications like QuickTime, Java, Nero etc. These things will run in the background and use up memory and CPU time. 4. Uninstall any applications you don't use/want. 5. Defragment your hard drive. (usually start->All Programs->Accessories->System Tools->Disk Defragmenter).
Your realized download speeds are correct. Internet speeds are measured in bits per second (bps). The results you get from speedtest is the speed in bps. However, in the real world files are not measured in bits, they are measured in Bytes, KiloBytes, MegaBytes, etc. So, when downloading actual files, your download speeds will be much lower. There are 8 Bits in a Byte There are 1024 Bytes in a Kilobyte There are 1024 Kilobytes in a Megabyte There are 1024 Megabytes in a Gigabyte etc... For example if you have a 2 Mbps Internet connection, it downloads at approximately 244 KB/s.(Kilobytes per second) Server loads and overhead can drive this speed much lower as described below. The speed and load on the server you are uploading to or downloading from also has to be accounted for. There is much overhead involved. The web server may be located in China. There may be 10,000 people simultaneously trying to access the same web server. Your connection may have to be routed through 15 or 20 hops (different locations) to reach the server, etc. Online torrents and game download servers such as STEAM are notorious for being extremely slow. They have thousands of users sharing the limited speed. Each user gets a small portion of the total speed. A rough estimate of actual download or upload speed can be made by dividing your Internet connection speed in bps by 10. For example a 20 Mbps cable Internet connection downloads at approximately 2 MB/s. I wrote an article http://isp1.us/article/internet-speeds/ that explains Internet download speeds in much more detail. Your Internet connection may be much faster than 1.8 Mbps. A poor WiFi signal can slow your connection immensely. Wireless signals are affected by many factors including distance, wall density, electrical interference, directional antenna range, etc. All of these factors will affect your actual wireless range, speed and connection quality. For serious gaming or video streaming your best bet is a direct Ethernet cable connection. Ethernet is unaffected by wireless interference and will give you a rock solid, stable network connection with very low latency (ping). If it is not feasible to run Ethernet cable the next best option would be a set of powerline network adapters http://isp1.us/reviews/netgear-xavb2101-powerline-adapter/ You plug one in by your router and one in the room where you need access and connect them to the devices with standard Ethernet patch cables. The network signals are transmitted over your existing home electrical wiring which will not be affected by wireless interference. There is still overhead in the connection but it is much more stable than WiFi. Try a speed test from a laptop or PC directly connected to the router via a Ethernet cable to see how much speed you are giving up for the convenience of a wireless connection. Remember, even if you use a Gigabit network such as Google fiber https://fiber.google.com/about/ that can transfer at a maximum of 1,000,000,000 bits per second, which equates to 1000 Mbps, you are still limited by the speed of the download server which could be as slow as molasses. Good Luck...
Well if you are sure that no one is using your wireless and you have ran a few speed checks then I would say where you are downloading from may be the problem. If the server is under stress that can do it as well. Just try to download something from some other sites and see if the problem continues. I would also try disabling your wireless part of your router and go directly to you computer. I have also seen routers that cause the slow down so if you want to make sure it isn't the router you can connect the modem to your computer directly.

Defrag your hard drive, run any spyware programs to clean out any spyware (I use IOBIT software. It's free, and can check for spyware), and check for any viruses. (I use AVG anti spyware. That, too, is free.) To defrag your HD, right-click on "C:\", and select "Properties". Click the "Tools" tab along the top, and click "Defragment Now ... ". Then follow the on-screen prompts. Good luck.
Clean windows registry can speed up the computer. Over time, you install new programs, uninstalled unimportant programs, update software's, install new devices, download files from the web, etcetera, hence embarking all records in the registry system. This is normal, but it is not wise to leave it untouched. Once in a while, you have to check and remove files that are no longer in use to maintain the speed of your PC. Clean registry make pc faster. http://registry-computer-cleaner.com/
Apart from having sufficient RAM and processing speed below are the few tips to deal with slow internet: 1. Try and user Google chrome Its light weight and fast you can get it for free from the following URL http://www.google.com/chrome 2. Download any good System Cleaner such as Reginout from Intel Software Directory (http://ibx.intel.com/directory/ ) to clear Browser history and cache because when the cache gets full, your browsing will slow down. 3. Make sure system is free of Mal wares and viruses use Avast free and Malware Bytes (FREE) 4. Sometimes your DNS server is not fast enough you can experiment with some third party DNS server Such as OpenDNS http://www.opendns.com. I tested this with two ISP connections found it very useful with One of them, didn’t get much difference in case of second ISP. 5. Always try and use a download manager. There are many free options available 6. Make sure your system firewall in enable and managed to stop unwanted internet traffic You can control access of programs to internet using windows Firewall
