I just got an Alfa AWUS036H high power USB wireless adapter. It works *great* on my PC laptop, picks up everything!

But I can't get it working on my iMac under 10.5.4.

I tried the Realtek RTL81878 driver (v1.4.7) on the CD that came with it. It installed, I could see under Network preferences as Ethernet Adapter 2 (ea2) and the Realtek USB WLAN Client Utility would show networks detected and occasionally it would connect, Network preferences would show en2 with a DHCP assigned IP address. Then it would immediately drop the connection. I tried my own network and some that were open, same results. The signals were 80%+ and like I said this worked great on the PC.

After finding nothing but a Vista driver on Alfa's website I downloaded the RTL81878B driver from Realtek (v1.5.1). The older driver said it was for 10.4 so I wondered if that was the issue, but the new one specifically said 10.4 and 10.5 during the install. Oh, I did remember to use the uninstall script from the first version before installing the new one.

Now the adapter shows up under Network preferences but the client won't launch - just keeps bouncing until I force quit.

Your right, the drivers for mac are for 10.4.x and do not work with 10.5.5

I had a hard time finding the right drivers too. I will gladly send them to VIA aim or email? The drivers do work on 10.5.5 (that's what I'm currently running on my MacBook) I can't recall where I actually found the drivers or I'd send you the link.
I can also confirm that this high powered adapter works GREAT! (with some extra help of a Yagi antenna!) I don't have problems with the client starting.

I'm having the same problem, but with a small twist. My old Powerbook G4 works great with the driver running 10.5.5, but my new MacBook Pro with 10.5.5 does not. Would this have something to do with the intel processor? Can someone post the link to download the driver that works with new Macs?! Any idea why I can't get both machines to work?

Thanks!

quicksilverG4 · Oct 24, 2008, 10:14 PM

Lori, that would be great! I'll send you a PM.

I tried the driver linked in the post below and it seems to work. Its v 1.5.1 vs 1.5.1A that I tried before.

Seems some folks are having trouble getting the MAC drivers for the ALFA USB device.

It's simple but sort of hidden on the distribution CD.
I don't have the details in front of me but I installed the drivers and client utility very easily.
Open the CD with Finder, search through the folders (if I had it right in front of me I'd be more specific) for a folder that has USB in its name. Then you can look in there for the "install package", install it and you should be okay.

If you bought the ALFA unit through Netgate.com they have the details.

Hi,

Just moved my laptop into a wooden cabinet and it significantly reduce the wireless transfer rate. My question is, can I add an external USB adapter or will it not work because of Apple's build in adapter? By adding an adapter with a wire, i can locate the adapter outside the cabinet. Thank you.

Big Mac · Dec 10, 2008, 08:35 PM

The adapter will work assuming there are drivers available for it. OS X doesn't have hardware conflicts.

asmithee · Dec 11, 2008, 02:38 AM

Thank you Big Mac.

In case people are searching for other USB WiFi adaptors, I've just installed a DLINK DWA-140 on a Mac Pro running 10.5.5 and it works well once you've installed the drivers. A config program appears in System Preferences.

hi there Lori and quicksiverG4,

Please help me. I have the same problem with my macbook also... Mac OS X 10.5. I have the same situation with quicksilver, I already installed the driver of realtek for 10.4/10.5 but it just keep on bouncing and bouncing... When i open the network preference, I see the ethernet en2 connected with ip address and subnet mask and says self-assigned ip address and may not be able to connect to the internet...im really hopeless..pls help... my email is <email removed>

Posting your email address is a great way to get lots of spam.

Also, the point of a forum is so people solve problems publicly, not one-on-one over email, so that we can all benefit.

chemron · Feb 9, 2009, 05:20 AM

I am sorry for my post but im really hopeless now to solve my problem... ;( Im just using windows now in my macbook.

chemron · Feb 10, 2009, 05:51 AM

any updates of this forum? please help...

chemron · Apr 7, 2009, 05:47 AM

Please reply this forum

I really need it.....

ghporter · Apr 7, 2009, 09:16 AM

chemron,

A "self assigned" IP address (usually starting with 169) means that the computer is set to obtain an address via DHCP and either the server it was looking for doesn't exist or didn't respond. Take a look at the network settings for this adapter in Windows and make sure you have things like gateway address set the same in OS X.

Once you do that, come back and tell us what happened.

I just got the AWUS036H USB Adapter and installed the driver for Mac 10.4 (my macbook is running 10.4.11). My Network Status indicates that "Aiport is connected to a network and that I'm connected to the Internet via airport". Also in Network Status I see the the "Ethernet Adaptor (en3) is currently active and has the IP address 192.xxx.xx.x

It doesn't seem like I have gotten any increased reception from the USB adapter. If I turn Airport off the Network Status states that " Ethernet Adaptor (en3) is currently active and has the IP address 192.xxx.xx.x You are connected to the Internet via Ethernet Adaptor (en3)" However, when I try to view a website nothing shows up even though the Realtek Client WLAN utility shows I am "connected" to a network and that the signal strength bar looks like it's over 50%

What can I do to get this adapter to work?

Thanks,

Peribonca

USB Wireless Adapters are too much trouble.

I'd get an Ethernet Wireless Adapter. No drivers required. They are configured via a web browser.

Bugje · Apr 30, 2009, 03:53 AM

It did not work in my macbook... I aready put the same IP address in windows, same gateway and same subnet mask but still didnt work... I used "configure manually" instead of using DHCP because if using DHCP the IP address is different, it starts woth 169..

Please help, i want to use the mac application...

chemron · May 29, 2009, 05:57 AM

In the network preference, it says im connected under the ethernet with color green but if ill open the safari or internet browser, i cant connect to it and says "you are not connected to the internet". What will i do? plss help me... I hope u can send me a private message so that I can meet you in skype or other messengers...

Please help ;(

snowwhite77 · Oct 11, 2009, 11:24 PM

I have the same problem as Peribonca! I also installed the driver for Mac 10.4 (macbook is running on 10.4.11), but I don't seem to be getting any increase of reception through the Alfa Awuso 36H.
I can see an "Ethernet Adapter (en2) in my System Preferences, is that what it's supposed to look like? Is an "Ethernet Adapter" supposed to strengthen the signal for wireless? I obviously have no idea...
Peribonca, will you please let me know whether you get the USB Adapter to work? And how?!
THANK YOU!!!
