you are likely running into the problem noted here:
For Internet access, using a USB 1.1 adapter will likely make little difference in how fast a web page loads. Your fastest consumer oriented broadband connection is running at some 3mbps, while USB 1.1 has a ceiling of 12 mbps. The upgrade to all USB 2.0 helps in LAN transfers.
First an apology - this may appear a bit messy with lots of queries in one but I will do my best.
I live in the UK and have just had broadband installed. Rather than have a load of cable through the house I opted for a Belkin Wireless G Router and a Belkin Wireless G USB Network adaptor.
It works fine, no probs. but here's the the thing. I only have USB 1.1 ports on my computer. I tried to install a Belkin 5 port USB 2.0 PCI card but I could not get the "NEC PCI to USB OPEN HOST CONTROLLER" to work, I gave up in the end.
Here at last, are the questions.
How much slower is the wireless network system compared to the ethernet cable?
In reality, how much slower am I running a USB2.0 Network adaptor through a USB1.1 port?
Any one know how to sort the "open host controller" probs? the drivers seem to work.
My computer is 4 years old but quick enough , running xp pro with no service packs (but with Norton anti virus).
Many, many thanks
P.S. My network icon says transfer rate is 11Mbits /sec
