Hi I have a belkin F5D8233-4v3 router but the speed isn't what it should be. I have a 100/10 Mbit connection but when I have my computer connected through the router with a cable all the speed tests I try stay at approximately 50 Mbits and if I am connected by wifi it's only less than 40 Mbits. When I connect the computer straight to the modem then the speed is 100 Mbits. What can be wrong?

The network card in your desktop computer either is 10 Mbit/second or 100 Mbit/second or 1000 Mbit/second. That's the speed that Windows will show.

The actual speed of downloads to your computer depends on how much money you pay your ISP (Internet Service Provider) every month, e.g,. 1 Mbit/second for $30, 7.5 Mbit/second for $45, 15 Mbit/second for $55.

Use a site like: http://SpeedTest.shaw.ca to measure your actual download/upload speeds.

Blu Ray players, draw alot of interference into the wireless router. Try moving your router into a different place, or somewhere away from your Blu Ray player.

i think your usb slot supports only version 1.1 Install a new external usb 2.0 card or higher.

USB versions and speed rates are as follows:

USB 1.0/1.1 - 1.5 Mbit/s (Low-Speed) and 12 Mbit/s (Full-Speed)
USB 2.0 - 480 Mbit/s (now called Hi-Speed)
USB 3.0 - 4.8 Gbit/s (SuperSpeed)

I am not sure you can fix it there or different USB types.

1. USB 1.0 Specified data rates of 1.5 Mbit/s (Low-Speed) and 12 Mbit/s (Full-Speed).
2. USB 2.0 Added higher maximum speed of 480 Mbit/s (now called Hi-Speed).

Only certian motherboards have the USB 2.0..

That would seem to be the issue..

this is from the d-link support page:
"Question :Why can't I get the advertised speed and performance when in Ad-Hoc mode? 
  
Answer : 

This FAQ applies to 802.11b, 802.11g, and Super G™products.

D-Link wireless products follow the IEEE 802.11 standards. The802.11b and 802.11g standards specify that Ad-Hoc mode only needsto support up to 11Mbps. For best results, use an access point orwireless router and set your adapters to Infrastructure (station)mode."

u need to increase the frequency in wi fi router settings.

Hi,

When using a laptop that has a N-wireless card the computer will to connect to a G-wireless router the laptop will be able to connect but because the router is a G-wireless the speeds will not be as fast. speeds around 10 to 20 Mbps is about normal. I don't know why your computer is saying that you are getting speeds around 108 Mbps. Residential computers don't reach speeds that fast but some business computers running off of an T-3 internet will have speeds up to that high so that they can keep up with large amount of data being transferred over there networks. As for the USB, i have seen an USB adapter that was g-wireless at at Wal-mart for about $20-30.

Hi! If you are using PC desktop computers and have a multiple USB connection, try connecting the usb at the back of the CPU cause front and rear connection has a different power speed. then restart. but if you are using a laptop install the belkin usb receiver driver first. Season Greetings to you!

First, you will need to restore the settings on your router, then get your laptop onto the network.
