|They are a few ways you can improve your speed. I've increased mine dramatically and was in a very similar situation.|
#1. Go to your "Wireless Network Connection Status" and click "Wireless Properties" click the security tab at the top and set the 3 drop boxes to as follows: 1st box - Security Type: No Authenication, 2nd box - Encryption Type: WEP, 3rd box - make a security key, use the 10 digit number that is located on your WiFi adapter between the 2 bar codes. That will stop other computers from intercepting your bandwidth.
#2. Go back to the "Wireless Network Connection Status" and click the administrative "Properties" this time. It may just say "Properties" with a shield in front of the word. Click the "Configure" button and another box will pop up. Click on the "Advanced" tab at the top, then under "Property:" they're a box with 6 things in it. You want to click "Recieve Buffers" and raise that value as high as it will go. It goes to 512 on mine. Next, go to "Transmit Buffers" and raise that value as high as you can, once again, mine is 512.
#3. Run an Ethernet Cord from the WiFi box to the computer if your computer has a 2nd Adapter for Ethernet. To check, go to the start menu, type in "Device Manager" and click on it when it pops up. Click the + sign beside "Network Adapters" and look to see if you have 2 adapters. You should click on both and make sure that they are "Enabled". This added an extra 100Mbps to my connection speed!
#4 Click on this link, or copy and paste it in your search engine and download the TCP/IP Optimizer, It's free. Make sure you click "save as" and download it to your desktop for easy access. When the download finishes, RIGHT click the TCP/IP Optimizer Icon and go to "Run As Administrator". Set your Max connection speed to the value of the highest connection speed between your adapters. Then click "optimal" at the bottom, it should be a bubble. Hit "apply" and when it asks, reboot.
