I just picked up a dlink usb wireless g adapter. Installed and working great.

I had a cisco 802.11b adapter before, but was having several issues with connectivity and speed.

I tested it out by watching a moving streaming from another pc. Was certainly much better than the old nic.

My question is the laptop I have it installed on is only usb1.1. What kind of impact does that have on networking performance?

Hi starjax,

The difference in USB1.1 and USB2.0 is speed. USB1.1 at full speed runs at 12Mbps. This is fine for most of the Internet connections in use today but is very slow in a true network environment. You won't see 54Mbps from your laptop using USB1.1 it's just not there.

USB2.0 on the other hand runs at 480Mbps. This is more than fast enough for most applications that it is used for today and should be good for the foreseeable future until other standards that start to match the IDE and PCI bus speeds that are used for the internal operations of a computer.
