The ZyXel USB ADSL Device is an affordable USB solution ideal for home users.

This device makes use of an Alcatel chipset – the MTK-20152 Two Chip Dynamite Solution chip which is made up of the USB Controller MTC 20158 and the AFE MTC-20154. This device also has a Globespan version wherein a Globespan chipset was used instead of the Alcatel chipset. The ZyXel USB ADSL Device Globespan version is more expensive. This robuts chipset is capable of carrying out USB and ATM onboard processing meaning that no CPU cycles are used up on the computer system to preserve a connection. The drivers for this device can be utilized for creating changes to the window size of the TCP which is the maximum data amount allowed to be sent by a sender without having to require an acknowledgement. This TCP window greatly aids in enhancing the throughput although it must be configured accurately to get the best results.
I have the same problem like ogli1. My Upload is ok,but the download is only 170 kbit/s. In Win XP there is no problem with the Zyxel USB-Stick. I tryed the latest drivers for Win Vista. In the first 30s when I start Win7 the download is ok,but after a few seconds it crashs down to 170kbits/s.
