AC adapter Wi-Fi

[G_Pap]

Hello to everyone,
I have an adapter which runs ac protocol. I disabled the built-in Wi-Fi but I can't see any improvement in my Wi-Fi network. I am in iMac 2011-27".
I'm not interested for the Internet, only for Wi-Fi. Maybe I have to set or change something.
My router is 300+1300 Mbps.
Any ideas please ?
Thanks.

Well it will work at what your iMac is capable of N speeds.

Thank you, this adapter (DWA-192 from DLink) is designed for 10.7 OS. It works also in my 10.10 OS.
It is ac. Why should I get N speeds ? I disabled the built-in Wi-Fi which is N. At N-2.4GHz (my simple network) there is no improvement also.

The "N" and "AC" (and so forth) protocols don't make the Internet magically faster -- the max speeds those machines refer to is intra-network transfer speeds (like sending a file from one machine to another on the same Wi-Fi network. Your Internet speed is limited to whatever your provider sold you -- you can check that against speedtest.net to see if you're getting what you are paying for (bearing in mind that the Wi-Fi speed will always be a bit slower than the Ethernet-connected speed).

 

[G_Pap]

Thanks, I'm interested only for Wi-Fi/LAN (Home Network) not for Internet. This is why I bought the adapter.
But I can't see any change. My iMac is N and this adapter is AC. I don't understand why isn't working well.

Is this adapter using USB 2 or USB 3 (bear in mind that this is not the same question as "do you have it plugged into a USB 2 or USB 3 port?")?

 

[G_Pap]

I'm using a converter from USB 2.0 to USB 3.0 via Thunderbolt, so it is using USB 3.0.
It's designed for USB 3.0 (for maximum results) and it is compatible with USB 2.0 .

 

[chas_m]

I don't understand what this means "I'm using a converter from USB 2.0 to USB 3.0 via Thunderbolt." What is it you are trying to say is USB 2? Plugging a USB 2 device into a USB 3 (or thunderbolt) port doesn't make it USB 3 speed -- it will still perform at USB 2.0 speeds regardless.

 

[G_Pap]

I use this device to convert my USB 2.0 port to USB 3.0. It is connected to Thunderbolt port.

 

[chscag]

That's a Thunderbolt to Ethernet + USB 3 adapter. All it does besides giving you an Ethernet port is allow you to use a USB 3 connection. (But it should allow Thunderbolt speeds.)

That's a Thunderbolt to Ethernet + USB 3 adapter. All it does besides giving you an Ethernet port is allow you to use a USB 3 connection. (But it should allow Thunderbolt speeds.)

^^^ That would be correct.

That is a USB 3 port on the adapter. The only converting the adapter does is pemit you to use a USB or ethernet device via your TB port.

It does not convert any USB 2 port to USB 3. It will not convert your existing USB 2 ports to USB 3.
USB 3 ports (including the one on the adapter) are, however, backwards compatible with USB 2 devices.
That is, you can plug a USB 2 device into the USB 3 port on the adapter, but the USB 2 device will still only run at USB 2 speed.
It will not convert a USB 2 device so that it runs at USB 3 speed.

edit:
This is also the 2nd or 3rd thread you've started with essentially the same question.
You have yet to tell us exactly what you are doing. There is not enough info.
You need to tell us what you are doing and how you are testing to possibly receive any answers to what is really your underlying question.
Specifically, what two computers are you using to test the transfer of data between devices on your network and what are the test results, along with the model # of any/all 3rd party network adapters you are using, and the setup of the wifi network itself and how every single device in the chain is connected.

If you are testing between your computer and your IPTV device - creating a better / faster network may not help you in the least, because the data transfer rate is going to be determined by the data transfer capability of your IPTV device. Having a faster wifi network is not going to somehow magically increase the output speed of the IPTV device. If you get the same data transfer rate with an n wifi network as you do with gigabit ethernet, an ac wifi network is not going to help you.

Hi there, I'm sorry-my apologies. It is not convert USB 2.0 port or USB 2.0 device to USB 3.0 of course. It converts TB to USB 3.0. By the way, I connected USB 3.0 adapter on this converter for maximum results and it seems to work good.
I'm using an iMac 2011-27" and IPTV device (Broadway from Hauppauge). You can see below my network test results. My adapters (which are connected with cable to devices (IPTV and iMac)) are running at 5GHz (at IPTV Netgear's WNCE3001 and at iMac DLink's AC1900) and they are all connected wirelessly to router.
With Ethernet cable from my router to iMac I still get the same results.

Yes the results will always be pretty much the same as explained.

 

[G_Pap]

I still cannot understand why I should get N speeds. If I get two of these devices, one in my IPTV and one in my iMac I will see improvement ?
My router is D6300 from Netgear (300+1300 Mbps).

 

[bobtomay]

What application are you using to test? What are you doing to test it? What type of data and size are moving between which two devices to do the test?

Measuring read and write speeds would be the measurement of the speed of a storage device (hard drive, SD card, etc) - that is not the measurement of the throughput speed of a network.

Measuring something that only takes 1.5 seconds - That is no test at all - and it is entirely likely that you may not see much difference at all between Firewire , USB, Thunderbolt, SATA, wifi, ethernet or anything else.

Try moving a 4 GB to 30 GB file or that much data between two devices to compare throughput speeds over several minutes.

If you are merely viewing a video from the IPTV device (that is watching a video on your computer while the IPTV device plays/streams it), and using gigabit ethernet from the IPTV all the way to your Mac, the speed is what it is. You are not going to get the IPTV device to "stream" faster. It is going to be limited by the speed at which it can read from the hard drive - and most DVR devices (at least here in the U.S.) all use 5400 RPM drives.

If you can actually open a Finder window and browse the folders on the IPTV device (assuming the IPTV device has a hard drive) and copy those files to your computer, that is what you need to be testing - the speed at which you can move large amounts of data. When I set up my media center, I tested transfers moving 100 GB at a time.

 

[G_Pap]

I'm using this test from Blackmagicdesign with 1GB file, it takes a long time (I stop it before it finishing): The results are the same for the built-in Wi-Fi or the AC adapter.
I'm not using Ethernet from IPTV to iMac but from router to IPTV. The result is the same with cable even wireless. I made a transfer from IPTV hard drive to my iMac and I get 6 MB/s with AC1900 adapter and 9 MB/s with built-in Wi-Fi iMac'a adapter.
As you understand I'm not familiar with Networking, hope my info help you to help me find a solution.

They answered to me from my IPTV and they said me that "there is H264 encoder inside on my IPTV hardware and this is why I get this quality and I don't need more."
But I need more and I don't know how to increase the quality.. The Ethernet port of IPTV is 100 Mbps. Whatever I tried (cable from router etc) I get always 6.5 Mbps.
Confused..

 

[G_Pap]

Is there a way to convert my 100 Mbps Ethernet port to Gigabit Ethernet ?

 

[bobtomay]

You need more for what?

You still have never stated what is the problem you are trying to solve besides wanting faster delivery.
What is the underlying issue you are trying to solve?

If the available throughput (100 Mbps) is already 15 times faster than what the IPTV device is apparently capable of outputting (6.5 Mbps), of what help is it going to be changing to a throughput with 150 times the available bandwidth the device is capable of delivering?

And the answer is likely no, you can't change it unless you know enough about electronics to go into the unit and remove the existing NIC which is probable soldered to the motherboard or integrated into the board, install another NIC and know how to get into the operating system of the IPTV device to install drivers for the new NIC.
