Any comments? I'd agree that these packet loss levels seem high. I've read and personally observed that packet loss levels about 5% tend to make a really lousy connections for interactive traffic like ssh and RDP(remote desktop). Packet loss on my neighborhood WLAN is generally under 1%, usually around 0.5% (half a percent). I do see rare spikes of 100% loss that usually goes away within 5 minutes or so. Do you have any info on the signal-to-noise ratios for that wireless link? It seems that you have a marginal connection that is fading in and out. Maybe a different antenna would help? If you have access to the config parameters, you may also benefit from setting the WLAN bitrates to lower settings (e.g. instead of 11 mbps, set it at 2 mbps). -Haudy
