Atheros AR982X based Mini PCI card very slow

[Sabex]

I have an atheros AR982X that has a very slow connection to my WiFi router.The router and net connection can cope with 30Mbps+ download speeds on other 802.11A/B devices and also on this particular card if I use Slackware or FreeBSD. With Haiku I only get download speeds in the kbps.Sometimes downloads just stall too.

I don't appear to be getting dropped packets:

Any ideas?

Now, why this is the case, I don't know; more likely than not it is a driver bug. What FreeBSD version did you test with? Did the problems start recently, or does R1/beta1 have them too?

I've used Slackware 14 and freebsd 12. I haven't tried the beta - I'll try it tonight.

I've tested Haiku R1/Beta vs the current Haiku nightly. It appears that performance is remarkably similar.

Maximum throughput measured with speedtest.net shows a maximum speed of approximately 14-16MBps with both releases. Pings to google.com averaged 22 and 26ms respectively which is close enough for military work, particularly when different servers could have been replying.

Performance of web pages in both Otter and Web+ are pretty horrific compared to FreeBSD 12 using Firefox but I am going to attribute the poor performance to the browsers, not to the kernel or kernel drivers in Haiku.

I will continue to perform further tests but I believe this ticket should be closed until I can narrow down what is going on. I will make a new ticket if I can find out anything further.

OK, thanks for the feedback!
