I have a Sony Vaio VGN-A197VP Notebook and a Zyxel Prestige 662HW-61 Wireless Access Point & ADSL Router.
I have no problems with ZyAIR G-220 IEEE 802.11b+g USB Adapter.
But when I use the internal wireless card (Intel Wireless Pro 200BG), the connection quality and speed is bad.
I have installed operating system (Windows XP SP2 with latest patches) and the latest driver for wireless nic (Intel Pro/2200 BG Driver Version: 9.0.1.9) and I have disable power saving mode for intel pro wireless adapter 2200BG. But the result is the same.
Could you please suggest me anything to solve this issue?
