Hi Larry,
The iwconfig I sent you is wrong, because I switched routers. The
router I had was a wireless N router, with which I had 12 percent
packet loss. The iwconfig you are seeing is with a wireless G
connection and now I only have 1 percent packet loss: the same as you
have. It appears that the relative packet loss is greater with an N
connection.
I have no idea why the loss should be greater with the N router than with the G
router.
How is the 2.4 GHz part of the N router configured? What make/model is it, and
what firmware is it running? Do you have the latest version?
My N router is a Netgear WNDR3300 normally running up to 270 Mbps at 5 GHz and
54 Mbps at 2.4 GHz; however, I changed it to run up to 270 Mbps in the 2.4 GHz
band. Again, I get 1% ping loss. My iwconfig output is
wlan12 IEEE 802.11bgn ESSID:"lwfdjf-n" Nickname:"rtl_wifi"

That link gets an upload speed measured with tcpperf of more than 80 Mbps.
I do not know why your N link is so lossy. The possible reasons are outdated
firmware in the router that was established in the pre-N days, or you have
noise/interference that affects the HT setup more than a simple G configuration.
