Wireless losing internet connection

I’m new to linux Opensuse 11.1 and I installed it on my labtop everything works great, but my wireless card a Belkin F506020 802.11B keeps losing the signal, even though on the bars it says it has a strong signal.

I have tried the madwifi with no success, and I tried using the original if and iw way but I just can not figure it out. :frowning:

Is there anyone that can help me understand this? I apologize in advance if I ask sme stupid questions lol.
