I have that same exact model and revision number of the router you have. Have you updated to the
latest firmware? Until reading this thread I just realized that I had not yet done so and noticed a quicker response from my internet connection. Be sure to follow the instructions in regards to resetting the router to factory default after performing the firmware upgrade or it will not take effect.
Also change the wireless channel used by your router to diffuse interference from other sources. I have also found connections with any router to be more reliable if you assign Static IP addresses to each of the computers on your network.
If you do not know how to access your routers web app it should be accessible by going to 192.168.1.1 through any web browser unless you changed the routers address. The default username is Admin and the default password is password.
After Router Reset
1. Connect via Ethernet cable
2. Launch any Web browser which will automatically direct you to the routers setup wizard. It will do most settings automatically at this time. I would suggest at this time to give your network a unique name, and set up Wireless security (WPA-PSK prefereably).
Note: Changing your routers default web access password does not work in this wizard though so do not bother at this point.
3. After the Wizard is finished connect your Wireless computers to the Network name you created and supply the encryption key you chose when your computer asks for it.
Changing your wireless channel
Static IP
You can give each computer an IP address that they will have every time they connect to your network. I have found this improves connection stability especially with local file sharing an network attached devices like printers.
1. Log in to your routers Web access
2. Click on "LAN IP Setup" in the left column
3. Under "Address Reservation" click "Add"
4. You will now see a list of all devices currently connected to your LAN
5. Click the radial button of one of the devices the "MAC Address", "IP Address", and "Device Name" should fill out automatically. You may change the IP Address if you want at this time
6. Click "Add"
7. repeat steps 3 to 6 for each device (the list of devices to add will shrink so one device does not get two IP addresses)
8. Click "Apply" when you are returned to "LAN IP Setup" and wait for your router to reset.

Hopefully this helps with your connection speed and stability.
