RTAC66U + EAN66 slowwwww ... help?

[disenter]

Can anyone give me advice on settings between these two devices?

I've tried everything I can think of and its just very slow in one direction.

I have my EAN66 running in ethernet adapter mode, plugged into my ps3's lan port, and it's running showtime for my media box. When I FTP into it, if I'm sending a file to it im lucky to get 3.5Mb/s.. moreso around 2-3Mb/s.
But if I pull a file from it, back to my machine, it gets around 12Mb/s. Fair enough it is working from a USB drive that is hanging off the ps3, and that does slow it down slightly, but not that much! - Have tested to internal drive as well and it suffers the same issue, but is a little faster...

Why is it so much slower to upload compared to download? It is the ONLY device on 5Ghz band, there are no 5Ghz networks around me, no interference at all..

It's quite annoying because I send to my 'media box' more than i need to download from it...

I am running Merlins latest version as of this post that is 3.0.0.4.374.39

5Ghz band has its own unique SSID with the following settings:

Hide SSID - No
Wireless mode - Auto (optimized for xbox is NOT checked)
Channel Bandwidth - 20/40/80 Mhz
Control Channel - Auto
Extension Channel - Auto
Auth Method - WPA2-Personal
WPA Encryption - AES
Key Rotation Interval - 3600

Enable radio - YES (obviously)
Scheduler - No
AP Isolated - No
Roaming Assistant - Disable
Enable IGMP Snooping - Disable
Multicast Rate - Auto
Preamble type - Auto
AMPDU RTS - Enable
RTS Threshold - 2347
DTIM Interval - 3
Beacon Inteval - 100
Enable TX Bursting - Enable
Enable WMM APSD - Enable
Optimize AMPDU aggregation - Disable
Optimize ack suppression - Disable
Explicit Beamforming - Enable
Regulation mode - OFF
Tx Power adjustment - 120mW (was running this at 200mW - seems to make little difference, except to range).

The EAN66 has very little configuration. Just set as ethernet mode, and it picks the rest up from the router... matches the channel used etc.

I have tried manually setting bandwidth, channels, changed power adjustment, made sure nothing else is around to interfere with the devices etc and nothing seems to make a difference!!!

Slow sending from RTAC66U to EAN66... but fast going from EAN66 to RTAC66U !!!

Any idea's please???? Ripping whats left of my hair out

edit: i see there is now a 3.0.0.4.374.40 firmware... so I'll read the notes and put that on an see if it helps - but still keen to hear about anyone elses idea's or experiences with same or similar setups

*Bump*

Any idea's?

Does no one find it strange that it would be so slow in one direction but not the other? or is this considered normal and im missing something??

Lots of people have problems with the ea66 and slow lan file transfers. Have you updated the EA66's firmware lately? An update was released in January. Have you updated your PC's network card drivers lately? Try manually setting your Control Channel to a lower channel like 40 and see if that helps.

Maybe post in this thread and see if these guys have found a resolution:

Thanks. I am running the latest firmware on the EA-N66 - 1.0.1.8k.
I hadn't tried to update my NIC drivers since my boards a bit older now, but I did anyway for the purpose of testing. Made no difference with the latest drivers as supplied by Asus.
I have tried all channels, and all ranges.. makes no difference.

I tried removing remote differential compression as suggested in that thread you posted, but this again, made no difference.

I will run some tests with my kids pc that connects to the same router via a lesser TP-Link usb Wifi adapter, and see if it suffers the same issue to try to see if it is the router, or the adapter.
But if its the adapter, it can go back to Asus. Pretty rediculous for the price of it that it should have this kind of crap going on...
I've lodged a ticket with them anyhow.. just have to wait and see.

Thanks for your ideas!

Do you have Windows Live Family Safety installed?

Nope, don't have that one.

I did some further testing...

Firstly, I measured the speed from my kids pc using his usual TP-Link 2.4ghz USB wifi adapter, just with windows file share. It achieved about 15-16mb/s both ways.

So I plugged the EA-N66 into that pc's LAN port and tried it. Download speed was about 16-17mb/s, and upload about 14-15mb/s.

Plug the EA-N66 back into the PS3, and back to 12mb/s download speed, and about 3mb/s upload while FTP'ing to it.

Now starting to think that somehow its the ps3, but unsure how. Have made sure its ethernet port is configured for full duplex as both 100 or 1000 link and makes no real difference, and even if it was that, its fine in one direction, so wtf yanno?

I even just tried putting a switch between the EA-N66 and the ps3 in case it is a interface thing, it should solve it... but no difference. All of 2mb/s sending to it right now.

Try this, goto your PS3's Network Settings and disable the Media Server Connection and do a test and see what speeds you get.

I did try that, had previously found mention of that being a factor, and it made sense that it might. But sadly, no effect.

I did watch the wifi logs on the router for a bit whilst trying to send some data back and forth and noticed that the connection shows that whilst there is activity the Tx rate will stay at 450Mbps, but the Rx keeps switching between 450 and 6, every 2-3 seconds... Perhaps it is just a faulty unit?

What is strange tho, is that if I plug it into the kids pc's Ethernet port, and just use windows file shares to move some files around, it doesn't suffer the same issue. Or not to the same extent. It's maybe 1mbps difference between upload and download.

This makes me wonder if it's more about the interface. PS3 to it's NIC and NIC to ean-66.

Not really sure where to go from here :/

My guess would be a faulty EA-N66. The first one I had would do the same thing. I had to power cycle it every few days to keep from it from 'stuttering'. I sent it back to Asus, and got another one under warranty. It is working well now with no issues.

Thanks. I have discussed it via support tickets with asus and they said rma it too

Cheers!

My PS3's lan connection is really slow when I set the link speed manually, but when I set it to "auto" it negotiates a gigabit connection that handles anything I can throw at it. Try changing that setting and testing again.
