Alfa AWUS 1900 won't work

[Tockman]

I've just installed Wireless USB Big Sur Adapter V9 on MacOS 12 Monterey b3. Installation went smooth and obviously successful (SIP is disabled). I gave permission to install third party kext, plugged adapter's USB connector in and rebooted. After that I see utility icon in menu, and system indicates USB connection (when I plug adapter's USB cable in and out) but doesn't recognize adapter itself. In System > Network > 802.11ac NIC tab I can see the status: "Cable for 802.11ac NIC isn't plugged or device doesn't respond". Looks like no proper driver (RTL8814) was installed. Is there any solution? Thank you again, Chris.

[Tockman]

NIC is recognized as USB2.0 device, not USB3.0 one. Both RtWlanU1827.kext and RtWlanU.kext are there in /Library/Extensions.

[Tockman]

Utility in Menu shows networks available but never able to connect to them.

[Tockman]

Special program for Alfa AWUS036ACH doesn't work for me - it not only shows NIC not plugged but even never finds available networks.

[chris1111]

Uninstall reboot then use latest release

[Tockman]

Just a dumb control question: if I'm on an unsupported Mac using Monterey with OCLP, should I use "OC" or "non-OC" version of utility? Is that a Hackintosh, technically?

[chris1111]

for non-OC! you suppose to have this message

[Tockman]

I guess, something might go wrong at the stage of pre-boot volume update. Will try one more time...

[Tockman]

No luck. And indicator on adapter even doesn't turn on.

[chris1111]

to turn on you need activate with pasword here

[Tockman]

Sure, I know it and I do it. It's my network, and it's password protected and WPA-enabled ;) After the password is entered utility tries to connect for some time, gets no success, and then icon in Menu changes from 'wifi' symbol back to 'device'.

[Tockman]

But the main question is - why doesn't my NIC get recognized by MacOS ("cable is disconnected")?

[chris1111]

So this is a Hardware issue probably relate to the Old mac patching try the adapter on other mac or Hackintosh and I almost certain it will work

[Tockman]

Chris, I need some help. Excuse me please for such kind of apply. Would you make a special program for my 1900 if I gave you original RtWlanU.kext and RtWlanU1827.kext from last official MacOS 10.15 driver? On your conditions, of course.

[Tockman]

Looks like it's not a hardware problem. Windows where I successfully installed my AWUS, lives in virtual machine on the same Mac. So, if USB ports are working OK in VR then they are normally working in general, right?

[chris1111]

1900 ?

[Tockman]

Yes. Alfa AWUS 1900. Just like in title.

[Tockman]

Still bad luck :(( Utility loads and shows all available networks. In System > Network - still "Cable unplugged, or device doesn't respond". Adapter doesn't turn on...
Thanks a lot for your effort and readiness to help, Chris!

[chris1111]

Its problematic with Alpha adapter here

[chris1111]

I told you I am prety sur problem is come from the old mac Patching system

[Tockman]

I see. But may be there's some way to overcome it...

[chris1111]

I never have a old mac patching system I can not help you

[chris1111]

Try this release
Wireless.USB.Big.Sur.Adapter-V-4.zip

[chris1111]

send me the old package AWUS 1900 or the driver and utility using for catalina

[chris1111]

We have also RtWlanDisk.kext on this program maybe thats the trick ?? I hope
Wireless USB Big Sur Adapter.zip

[Tockman]

Maybe. Will give it a try. Thanks!

[chris1111]

Maybe. Will give it a try. Thanks!

I think this is work for Alfa awus 1900

[chris1111]

HA ha its work with a TL WN821N

[Tockman]

And TL-WN821N is USB 2.0 802.11N adapter.

[chris1111]

And TL-WN821N is USB 2.0 802.11N adapter.

Yes its old
see drivers install without issue working great

Probably working on other I make test I have 5 more adapter

[chris1111]

Test Working
TL WN722N V2
edimax ew 7722utn v2
TL-WN823N V3
Edimax Wi-Fi N150

[Tockman]

No, no, no :( Ain't no sunshine. Neither v4, nor special one with RtWlanDisk.kext - no work.
I feel the single solution left is to install last supported macOS (in my case 10.15.7) and original driver.
Thank you one more time.

[Tockman]

Is it something different than you offered here?

[chris1111]

Is it something different than you offered here?

No this is the same

[Tockman]

I refer to it as "special one with RtWlanDisk.kext".

[chris1111]

I refer to it as "special one with RtWlanDisk.kext".

Yes

[Tockman]

I've tried everything you gave. Result is negative :(

[chris1111]

With OC ?

[Tockman]

But you told me OC's not my case?

[chris1111]

i never told you this, you told me posting in wrong thread and I sais special program exist also for OC

[Tockman]

#130 (reply in thread)
I asked you: "Just a dumb control question: if I'm on an unsupported Mac using Monterey with OCLP, should I use "OC" or "non-OC" version of utility? Is that a Hackintosh, technically?"
Your answer was: "for non-OC! you suppose to have this message..."

[chris1111]

Thats nothing to do with (not my case?)

[Tockman]

I really don't know what way your utility would interact with Open Core Legacy Patcher. So all that's left for me is to ask and believe ;)

[chris1111]

Open Core Legacy Patcher Installe OC in EFI partition this is correct

[Tockman]

Utility = StatusBarApp, I mean.

[chris1111]

Utility = StatusBarApp, I mean.

The network utility would not work at all if the driver was not loaded.

[Tockman]

So that's a mystery!

[Tockman]

You saw my screenshot. macOS sees my NIC as disconnected or unplugged. Usually this happens when driver didn't install correctly.

[Tockman]

Or maybe that's an USB failure, as I meant before. But since my USB ports works normally in virtual machine I can conclude it's a software problem, not hardware one.

[Tockman]

Today after installing macOS 12.4 b4 your driver gave up to load - for the first time since install. By the way, does system extension by Marvell Semiconductor relate to some component of the driver? Because I got a message of its blocking.

[Tockman]

Reinstallation didn't help. It seems that OS just prevents Realtek kext from loading.
RtWlanU1827 and RtWlanU are still in Extensions folder but there's no more USB adapter among network devices.

[chris1111]

I was surprised by your comment so I rushed to test it
you are wrong my friend
Iam on MacBookPro-retina-late-2013
With out OCLP, only SIP disable for test it

I will test SIP Enable next post

[chris1111]

SIP Enable also works

[Tockman]

Thank you for your fast reaction!
So may be that's a kind of interference with OCLP (0.4.4, in my case)?

[Tockman]

Tried to reinstall once more - no luck. After installation there's no demand to confirm permission for Realtek drivers. I think, that's because they are already in a trusted list. Drivers are in Extensions folder. Icon is here in dock but red-crossed. May be, the reason is installer sees SIP as disabled, but in fact it's enabled, with just SSV turned-out?

[Tockman]

And what if I copy/replace RtWlanU1827 and RtWlanU to /EFI/OC/kexts folder? Will they load at startup then?

[chris1111]

You here Wireless USB Big Sur Adapter there is no OC or Clover here

SIP Enable also works

Note: You can Enable and Disable the SIP from OpenCore, It works the same way.

[Tockman]

You here Wireless USB Big Sur Adapter there is no OC or Clover here

Yes, I know. But this very version worked on my machine in the run of whole year. And now it won't load, and I ask you what I'd do.
Also I was strongly advised not to enable SIP permanently (#130 (reply in thread)). My macOS runs with OpenCore Legacy Patcher, so I asked if there is some reason to place kext files into EFI.

[chris1111]

kext file in EFI for OpenCore works wit this but SIP disable
But your not need to place any kexts, the program do it for you
Wireless-USB-OC-Big-Sur-Adapter

[Tockman]

Look what I found! System Report > Extensions: Loading not supported for both kexts.


Third line from bottom "Возможна загрузка: Не поддерживается" means "Possibility of load: Not supported".

[chris1111]

I am not use OCLP you have to use the program Wireless-USB-OC-Big-Sur-Adapter from the readme SIP must be disable

[Tockman]

But it is disabled! And I used to have Wireless-USB-Big-Sur-Adapter (non-OC) before yesterday, and it worked normally. Now it runs through installation, but kexts won't load. OK, if you suggest that now I have to try OC version, I'll give it a try.

[chris1111]

both way works from all tree program
Enable/Disable
follow the guide corectly

[chris1111]

You seem to mix the programs you want to use the kexts injections Opencore so dont use the one which is designed for the Library/Extensions.

[Tockman]

Yes, you were right - OC version installed kexts and got working. Thank you for your time!

[Tockman]

@chris1111, I've just realized that, due to some changes made to OCLP architecture (in particular, offline install mode only available), during OCLP upgrade (from 0.4.4 to 0.4.5) all previous installed kexts have been wiped out from EFI/OC/Kext, and I had to reinstall Wireless USB OC Big Sur to get my adapter working. I'm seeing it for the second time now. So, is reinstall the single possibility, or may be there's any solution to keep kexts where they are? Thank you.

[chris1111]

Yes you can try to make a copy of the both kexts then rename it RtWlanU
RtWlanU1827 it will apear at folder, after OCLP update rename it at RtWlanU.kext
RtWlanU1827.kext
I dont think OCLP delete the two folder 😁 But chek your config.plist if the kext is enable, if not enable the both kexts

[Tockman]

Hi chris,

since there's no dedicated discussion thread for D-LinkUtility-Package I allow myself to write it there. At last I've bought AWUS036ACM (based on Mediatek chip) and installed your driver for it. Good news is that adapter is really displayed as USB3 device (up to 5 Gb/sec).

And the bad one - it's seen by Monterey as 802.11N device, not 802.11AC one. Accordingly, the connection speed is limited to 300 Mb/sec, and that's very poor for Gigabyte network.

Are there some thoughts on how it might be fixed? Thank you!

[chris1111]

Yea I told you about the Mediatek chip its support USB 3 but this Drivers is not really full stable, some time it can disconected then no solution exist for anny issue about this chip.
