It really is hard for me to visualize how this USB2 dongle is capable of pumping 600 Mbps while the USB2 spec limits to 400 Mbps.


#3

That’s not the speed through the USB 2.
600 Mbps represents the maximum theoretical bandwidth being the total of the 2 available bands or frequencies. (2.4G 150M / 5.8G 430M)
Theoretical Lab , not real world.
USB 2.0 standard can theoretically transfer data at 480 megabits per second.

This thing is pretty good. I purchased it for my Rock64 and tried it on my K1 Pro CE.
Much better than stock wifi in the K1 Pro.
Using this wifi dongle I get the maximum speed-test 55 Mbps Download available from my ISP.
AC Router is 30 Metres away on another floor.
I paid $13.00 AUD so not a bad thing.


#4

It’s not. Only capable of USB2 max throughput. The max theoretical bandwidth could only (possibly) be achieved using USB3. The sellers get away with murder with their deceptive descriptions :lying_face:


#5

Are you saying 2.4G 150 Mbps and 5.8G 430 Mbps theoretical speeds are USB 3 only in the Manufacturers specs i supplied ?


#6

I can’t go above 310 Mbps with usb 3.0 ethernet adapter connected on usb 2.0 port. But, isn’t that enough even for 4k?


#7

I’ll let others who use 4k tell you it’s enough. I don’t have 4k anything. The only thing you may have to tweak https://kodi.wiki/view/HOW-TO%3AModify_the_video_cache


#8

OK.

Is this Rock64 based on an RK3368 CPU?

That looks good to me, especially your device is 30 Meters away on another floor.


#9

Rockchip******RK3328


#10

Can you confirm from the dmesg output log that it uses the chipset Realtek8811AU?

BTW, the one you showed on the picture is a white color. I found on eBay with a black color and it was US $7.59. Is it a good price?


#11

My specs are correct as first post. dmesg yes Realtek8811AU
I paid $12.50 AUD from retail store Australia.


#12

You can use iperf and test against a PC with a gigabit ethernet connection to your router.
That would produce much more reliable results than speed testing with your ISP.

The 300mbps that you can get from a USB 3.0 gigabit ethernet adapter is plenty fast for 4K/HDR. You really need about 150mbps, so 100mbps ethernet isn’t enough in many cases.


#13

I got a ‘gigabit’ ethernet usb to replace the default 100mbps buildin eth0 of my s905 boxes.

It registers as ASIX AX88178 USB 2.0 Ethernet and it works fine


#14

Well, the specs of 4K Bluray is 128 Mbit/s at it highest. I’ve never encountered problems with my S905X box with full 50-60 GB rips, yet I’ve added buffering settings in Advancedsettings to make sure that if there are some bitrate spikes that won’t be a problem with my 93-94 Mbit/s connection.

Regarding an USB 3 Gigabit adapter, I purchased a 8153 Realtek Semiconductor Corp. RTL8153 adapter which I’ve measured several times to 330-340 Mbit/s with iperf3 and I play the 300 Mbit/s Jellyfish clip without stuttering. However, I’m facing some issues with CE and PKC on high bitrate file in the beginning of a clip, and I’m not quite sure if it’s kernel, software or hardware related as it works perfectly 7 of 10 times…

Results from running iperf3 - I get a few lower Mbit/s when I’m actually sending a file from my hard drive and not just thrash data as seen below. One interesting thing is that when I do a traceroute to my server, the Gbit adapter uses nearly 2x the time of the standard eth0 interface.

I am saying that the theoretical MAXIMUM combined speed (600Mbs) is not even possible on USB2 and therefore misrepresented by any manufacturer that says it is or includes it in the spec of a USB2 device (which is unable to deliver that speed and so lowers the theoretical maximum speed to 480Mbps) :thinking:


#16

Do you remember how much throughput you can get with this Asix AX88178 USB2LAN adapter? A while back and IIRC, I tested an Asix AX8872 USB2LAN (100 Mbps) adapter on my Seagate Dockstar and was able to get about 87 Mbps throughput when connected to an RJ-45 port on my 100 Mbps router.


#17

I get about 300mbps,which is more than sufficient.


#18

I have a generic Realtek8811AU USB 2.0 wifi adapter. What do I need to do to get it to work? Nothing happens when I plug it into my MeCool box.


#19

Does that mean the adapter light doesn’t blink or what ? The light should blink meaning the adapter is recognised.


#20

As I stated in the topic in the evaluation forum, the light blinks but I have no idea if it’s actually doing anything. The connection speed is exactly the same. Do I have to do something to turn off the MeCool’s default wifi?

Nevermind. I changed my router to ac only and now my connection is slower. There’s something going on in here between the traffic from my neighbors and the age of the building. I’m going to have to try a Mesh setup.
