Tried to connect to wanadoo wireless today with wireless link supplied by wanadoo. Warning message stating "Connecting high-speed USB device to non-high speed USB Hub may cause performance probs." My laptop failed to recognise any wireless networks during set-up. Would this be the cause and if so, Is it possible to the create a high speed USB hub. Laptop specs - medion, 2ghz, 2 USB, 20gb, windows xp,

Would you expect a racing car on a racetrack to go at the same speed as a small car on a country road ?..Can you slow down the speed of the fastest USB ?, this will give the slower speed connection time to act on the data before being overwelmed by more data than it can handle, or possibly can you upgrade the slow speed device to usb 2?.

Your USB hub is rated at USB 1 speed. That is as fast as it will go. You have attached a USB 2 device to it and Windows is telling you that at best it will only run at USB 1 speed - sometimes they will not run at all.

To run a USB 2 device, either plug it directly into a USB 2 port on your computer (if you have one) or into a USB 2 hub which itself is plugged into a USB 2 port.

Some devices need a significant power supply from the USB connection. It is better to plug these directly into the computer.

<<Is it possible to the create a high speed USB hub.>>

To implement USB 2.0 in your laptop, you need to get a PCMCIA card with USB 2.0 ports.

USB 1.1 running at 12Mpbs is too slow if you are trying to use 802.11g WiFi, which has a nominal speed of 54Mbps. USB 2.0 runs at 480Mbps.

Having said that, running at USB 1.1 speeds isn't a problem for internet access as broadband speeds are much slower relatively, but for file transfer across a network you want the fastest speeds possible.
