TL-WN727N as WAN interface

[stephenw10]

That's a 150Mbps device so 802.11n 1x1. The absolute maximum I would expect to se through it would be ~100Mbps but that would be in ideal conditions.

What link speed is it actually connecting at? What is it connecting to?

[bavcon22]

@stephenw10 I'm sorry for late response. I made connection from USB to wifi dongle to my phone Xiaomi hotspot and then with my new TP-Link device M7350 and I had the same results with Speedtest. When I connect my phone to M7350 I had much better speeds. To see exact connection speed I have to retested it.

Sincerely yours

[stephenw10]

You should run ifconfig -vvv against the wifi interface when it's connected to see the link speed is. Or check Status > Interfaces but the output there may or may not show it depending on the driver.
Results from your phone to an AP are almost always going to be far better. It's probably using at least 802.11ac 2x2.

@stephenw10 Here it is reply from your command for my WWAN interface on pfSense+ 22.05:

I saw that interface is connected with 11g, but the WiFi module (TL-WN727N) and the device M7350 has 11n network capability and the distance is less then 1m one device from another.

@bavcon22 I know this is a long shot, but, cloud it be inserted in a USB 1.1 port by any chance? Or have a USB controller run in 1.1 speed? Again, I know it is a long shot.

[bavcon22]

Speed test results:

[bavcon22]

@nightlyshark The WiFi module is connected to Lenovo ThinkCentre M9xp (x is an number) to USB 3.0 port. Is the USB 3.0 a problem the wifi device is USB 2.0?

[NightlyShark]

@bavcon22 It is a problem if the port drops to 1.1. I don't know if this can be caused by a rusted connector, driver (both controller and chipset) or something...

[NightlyShark]

@bavcon22 said in TL-WN727N as WAN interface:

Lenovo ThinkCentre M9xp

Do you need any OEM chipset (more like, on-CPU-controller) drivers for the AMD Lenovo-specific (most likely), CPU?

[stephenw10]

Hmm, I don't have one I can test in station mode. In hostap mode though the Status > Interfaces page does show the link 'Rate'. Do you see that?

[NightlyShark]

@stephenw10 Maybe you can whip-up a VM in a PC, pass-trough a USB controller and test it from there?

[bavcon22]

@nightlyshark The PC has USB 2.0 connectors I will try it. Next weekend I have intent to update my pfsense+ 12.05 to 13.01 and then I will give the feedback in this forum.

[NightlyShark]

@stephenw10 Sorry, replied to the wrong answer.

[bavcon22]

@bavcon22 Speedtest results with USB 2.0 PC port:

No better results.
Thank you for all, I will see if any better results with newer version of pfSense+ afrer I will update the software.

[NightlyShark]

@bavcon22 There is always the case that the adapter has some damaged component that causes it to drop to a USB 1.1 mode, or just be like that from factory (highly unlikely).

[bavcon22]

@nightlyshark I will try to connect this dongle tp-link tl-wn727n to Raspberry Pi to "see" if the device actually work with 11n connection with different OS's and than report back what I will find.

[bavcon22]

@bavcon22 I tested the dongle on PC x86 x64 with Linux mint OS.
Testing specs:

OS: Linux mint 21.1 cinnamon
PC: Acer Aspire 5 A515-45-R5X9
USB: dongle conected to USB3 on PC, USB2 on dongle
Connection: via Android phone or home wifi
Conected: LAN
Speedtest results ~30Mbit simetric on bought wifi devices.

I think the dongle is capable of 11n transmission.

[stephenw10]

Were you able to see what the reported connection 'rate' was in pfSense?

[NightlyShark]

@bavcon22 Judging from my bad experiences with TP-Link Wi-Fi adapters, maybe try another adapter? 30 Mbits is still pretty low. I owned such an adapter, and I had to manually resolder the antenna connections (many years ago, though). My point is, they are unreliable and unpredictable.
