>Description:
I've been testing a supposedly supported Atheros WiFi card to see if it
would work better with 6.7 than it did with 6.6, but unfortunately not.
It's an AR9287 chip on a PCI-express 1x card. I'll provide some details
below, and I'd be happy to test any patches and suggestions.
(PS. the WiFi card works great when I boot the PC into Linux)
while transferring a 440 MiB file on 802.11g
============================================
--- 192.168.1.1 ping statistics ---
641 packets transmitted, 640 packets received, 0.2% packet loss
round-trip min/avg/max/std-dev = 12.367/1577.347/6751.938/1530.703 ms
transfer speed swung between 200 and 1200 Kbit/s, averaging 700 Kbit/s
45 minutes of idle network on 802.11g
=====================================
--- 192.168.1.1 ping statistics ---
2937 packets transmitted, 2924 packets received, 0.4% packet loss
round-trip min/avg/max/std-dev = 11.577/47.667/310.944/34.576 ms
trying to transfer the same 440 MiB file but on 802.11n
=======================================================
the machine's network freezes repeatedly, and ping(8) outputs lots of:
ping: sendmsg: No buffer space available
ping: wrote 192.168.1.1 64 chars, ret=-1
--- 192.168.1.1 ping statistics ---
348 packets transmitted, 227 packets received, 34.8% packet loss
round-trip min/avg/max/std-dev = 29.615/2467.639/6041.608/1004.679 ms
