回複：回複：求助: Dlink 601路由器無線上網

the card is: Realtek RTL8188SU Wireless LAN 802.11n USB 2.0 Network Adapter

the channel is set to 20/40 if i remember it right, and it says it is the best possible setting per the manual.

it works ok now, have 3-4M speed, but still lower than the beginning of 10M when i set it up.

If happens again, i will change the router instead.

thanks
