Jun 20, 2014 11:48 PM in response to veggietecby johnniecache,Yes, even when you have no disconnects, performance is also really bad. Look at my comparison of windows and mavericks on page 29 of this thread. I get a maximum of 15-20 MB/s download speed over 5GHz. Also the transfer "collapses" every 30 seconds, see this screenshot:
Now look at my Windows results:

Jun 21, 2014 9:14 AM in response to johnniecacheby veggietec,I tested it now on both systems (Win8.1 Bootcamp). 11,5MB/s (~90Mbit although my wi-fi can handle 300..) on both systems, so the final test will be on monday at work. If the speed in another wi-fi network is still that slow it is definitly a hardware problem...

1. Its the same test setup, same hardware, but 3x the transfer rate on windows?
2. Large file transfer collapses on mavericks several time, see picture

If its 802.11n, i think your transfer speed is ok. What about the stability? You said it slowed down on Mac OS, did you experience the same problems on Windows?

Jun 21, 2014 9:55 AM in response to johnniecacheby veggietec,yeah it's 802.11n but I lack of around 7MB/s. On your screen you have 44MB/s - do you use an 'ac'-network?
After I deactivated the 2.4GHz wi-fi setup on my router the 11,5MB/s on Mac OS were constant like on the bootcamp Win setup. (Unfortunately my printer can't connect to a 5GHz, so I need the 2.4 wi-fi...)But on 802.11n the speed should be at around 18MB/s not 11,5 - maybe due to other wi-fi networks around my appartment I have this 7MB/s lack?
I'll check if a wi-fi channel change can help. -
Jun 21, 2014 10:29 AM in response to veggietecby veggietec,Okay... apparently after turning off the 2.4GHz wi-if on my router and changing the channel after reading this page, I have constantly 2-4ms to my router on pinging (down from 30-80ms before) and the transfer rate to my NAS after 8GB is at around 10.5-11.5MB/s...

Jun 21, 2014 1:40 PM in response to veggietecby johnniecache,hm.. just curious. If your router is only 802.11n, does it have Gigabit Ethernet? How did you connect your NAS to the router? If its a 100Mbit Ethernet Port on the router, that perfectly explains your bottleneck of 11.5 MB/s.
Btw, i also have a printer that needs 2.4 GHz, but modern routers can provide 2.4 GHz and 5Ghz simultaneously.
-
Jun 21, 2014 2:14 PM in response to johnniecacheby veggietec,Yes the router has 4 Gigabit slots and the NAS can also provide Gigabit. (via Ethernet I have a transfer speed of 70MB/s between NAS & PC)
About the 2.4 & 5 GHz..The router can simultanesouly run both frequencies, but with 2.4GHz activated there is some packet loss

Jun 21, 2014 11:37 PM in response to johnniecacheby 4rk,Testing network speed with file transfers is kind of spotty.
Without installing anything (though you need two machines on a network) you can use netcat to test some transfers as described in:
Change the bs=1000M to bs=1048576000 on a mac, or lop off a couple zeros to get your answer faster, also your answer will be harder to read showing bytes/s.
EG on one machine I did (in two terminals):
nc -v -l -n 20000 >/dev/null
and:
dd if=/dev/zero bs=12485760 count=10 | nc -v -v -n 127.0.0.1 20000
to get (without using a real network, just the loop in the kernel) ~249MB/s
as: 10104857600 bytes transferred in 38.628004 secs (261594091 bytes/sec)
That's ~2090Mbps
If you like something a little more robust look at http://iperf.fr/ again, you'll need two machines, not just a machine and NAS.

Jun 30, 2014 1:15 PM in response to ShaneD90by João Nunes,10.9.4 out!! Let's try to see if it fixed
-
Jun 30, 2014 3:16 PM in response to João Nunesby PoloMac,EUREKA
They have fixed what they said was not broken
8 months of dropout misery ends (:->

Jun 30, 2014 4:01 PM in response to PoloMacby 4rk,Can you be more specific? What was fixed how did you confirm that and what are the new wifi version numbers?
-
Jun 30, 2014 4:35 PM in response to 4rkby PoloMac,Update to 10.9.4 and see if your issues are resolved
Mine are
