I have one computer connected with wire to a wireless router and a notebook with a wireless pc-card. The router and card is 54 mbit/s. Even if i place the notebook next to the router I can only transfer files at a speed of 3 mbit/s. Windows says that connection speed is 54 and signal strenght is very high. What is wrong?

Well, while your notebook may be in close proximity to the router and the signal strength is high, there my be interference from your other electronic components or other wirless networks in your neighborhood.

Moving your router or laptop may help. Switching the channel used by your network may help. Checking to make sure your network card is set to full duplex mode will always help.

Try your manufacturer's website for tips on setting up your home network.

Happy networking,

I think you should use the software, and go from there.

One more thing you could do is make sure there isn't anythign blocking the signal.

When i try to start the software that came with the pc-card it doesn't start. Nothing happens. The router and pc-card is by D-link. The only wireless thing I can think of is our phones. The base stands less that 1 meter from the router. Can that be it?
I'm using encryption on the network.

Look at the speed that tyour router is set up sometimes is Auto and it gets low bandwith i fix my wrt54g to be always at 54mbps (it has 2 4 6 11 54 mbps options) maybe you can try that

Umm if the phone is in the 2.4 GHz range it can interfere. Windows should fall back though. So unless you have the drivers your computer can'r communicate well with the card. Either that or the card needs RMA.

THEORY: The maximum theoretical file transfer rate for a 54 Mbps system is actually 27 Mbps (Considering 10 bits per byte in transferring files).

What kind of wireless card and router/access-point are you using?

Maybe you should try a repeater... that might amplifies the signal to get you a better signal into your wireless device... They also have devices that are specially made for amplifying yoru signal... check that out, maybe that could help...

i have Orinoco USB Card, wireless!

very good

could it be that someone is stealing your connection. This happen in my country
