I haven’t done Linux since before it had Wireless support, and have never had to tinker with network settings, so I am at a loss.
My searching may be weak, but when I tried, I found nothing relevant except to determine some of the things usually asked for in threads of this nature.
The symptom is very slow connection when using wireless, but it does fine when I hardwire it. Using Windows 7 on the same system it flows nicely.
The results from “ping -c20 -s 1400 192.168.1.1” shows what I think is the symptom at the heart of the issue…
20 packets transmitted, 17 received, 15% packet loss, time 19032ms
rtt min/avg/max/mdev = 50.986/587.876/1684.511/470.164 ms, pipe 2
On Windows 7, or with the wired connection, I get sun 1ms responses, as I would expect.
The output of iwconfig:
lo no wireless extensions.
eth0 no wireless extensions.
wmaster0 no wireless extensions.

I have just completed a clean install, and have done nothing (beyond rebooting) except to extract Eclipse and the Android SDK in my home directory, and upgrade Firefox to 3.6.3. I checked for and installed updates using YAST.
Any help would be appreciated greatly.
Without knowledge of the manufacturer of your wireless device and the
kernel version you are running, we can do little. I have no idea what an
Acer Aspire One is, and I will not do your research.
I have used the madwifi drivers on my Acer Aspire One with very good results, though not in Suse. I think you might want to check it out as an option though. Usually installing these drivers is not too difficult, and I believe there is even an one click install available for them: Atheros madwifi - openSUSE
Without more info, it is hard to say if this will fix your slow throughput, but just as a guess, I think it may help.
Cheers,

The only security I have on my Linksys WRT54G2 V1.5 802.11 B/G router is MAC address checking, and since this is coming from Linux (slowly) it seems to confirm that the MAC address on the router is ok.
I only want to go to madwifi if I can’t fix this up with native suse configuration because I hear the drivers are old… but thanks for the suggestion/reminder. 
Maybe this symptom will ring a bell for someone… or stir some curiosity.
I get very slow ping times, but as soon as my screen blanks the time goes to around an average of 0.6 ms, and then returns back to a high latency when I move the mouse and the screen comes back on.
