I have a ALFA GE-RTL8188 USB WIFI Adapter installed on my PC on Bord. The adapter is working under Windows 7 but not under the Navigatrix installation 0.5. The adapter can locate the WIFI nets in the surrounding but it is not going to cnnect me. I do have a Lunix driver for the adapter supplied with the Alfa on a CD. How do I get this driver installed from the CD or in any other way to make the USB WIFI adapter working.

I was thinking "it should work" and then, "Ah, I remember..." I think you would actually would have the same problem with the driver on the disk.

As I remember, the module (driver) needs to be set to a different mode. I have to look it up again and come back.

To make sure we're takling about the same thing; open a terminal and enter:LiSt MODules PIPE the list to search Global Regular Expression and Print all occurances of 802 or rtl

This will list the modules the machine thinks it's suppose to use for the wireless. Cut and paste the output. It will look like:

This is another fun one...

sudo lshw -C network

It will list the drivers actually connected to the hardware.

I mention this because I'm having a tough time finding what I thought I remembered...still looking.

Hi Moe,

I have done the first part of it and the result is the same as in your example. What is the next step I have to do to get it working?

You said your output was the same. Let's see if it's loading the firmware.

dmesg |grep rtl8192cu

I have netered the command:
dmesg |grep rtl8192cu

the result is the same like in your message, only the Board Type is set 1 and not 0 like in your message

What is the full model number stamped on the bottom? What is the output of the command

LiSt USB devices. It will print out 6-8 lines of text.This tells us what seat each device has on the bus. The ID 20f4:648b tells us the Manufacturer; and after the colon: the product. So humans don't feel neglected it may also give the name of the manufacturer, the product and less frequently, a hint about what it does.

Surprise-surprize many $400 things have the same chip that is in the $40 thing, or the name brand plactic on the outside is plactic shell for a different company on the inside. Also the chip designers mess with us by creating a group that's like a family that doesn't always get along.

• rtl8192c
• rtl8192ce
• rtl8192cu
• rtl8192de
• rtl8192se

Same company, same family, same function; five different drivers....

We'll I've raved until I was tired. I'll look tomorrow.

What is the name of the file that contains the linux driver?

It gives me the following results:

BUS 001 Device009: ID DBDA:817F Realtek Semiconduktor Corp. RTL8188RU 802.11 WLAN Adapter

there are mor lines to follow for other USB devices

It's actually 0bda:817F. You can cut the time/hassle confusion by using your mouse to highlight text and Edit> Copy|Paste to move output around.


Try this...
as SuperUser DO a MODule PROBE -Remove, using Force (if necessary) and be Vocal about it with module rtl8192cu

Now with the module removed it is re-installed with a different setting.

-Vocally install module rtl8192cu setting option swenc to Yes.

Give that a whirl.

If the machine is still unhappy, repeat the first step and then to see if the there's a difference.

I have the rtl8188cus and had to blacklist drivers by changing a file as shown here:

http://ubuntuforums.org/showthread.php?t=2092934

I am not sure if you will need to blacklist but it is possible.

Both links are good resources. It just becomes a little merky because the Realtek modules are already installed in Navigatrix as opposed to other distributions that need to download and install them.

One of the links states:
The r8712u is already located /lib/modules/3.8.11-dsp/kernel/drivers/staging/rtl8712/r8712u.ko

The question is if the listed intended module that is automagically picked up doesn't work, will blacklisting it and using a module that appears to work with a Dlink DWA-131 work? I don't know.

I also don't know if by some cruel twist of fate there are varients of rtl8192cu with the same name floating around...some of which work for the Alfa GE-RTL8188 USB WIFI Adapter....or is it a relabled Alfa AWUS036NHR...and some do not.

Hello,

I have tried everything you mentioned, but no positive result. I have installed even the rtl8712 and r8712u.ko but no result. I can see the different WIFI available in the window, including my personal WIFI. On my Lenovo laptop with the build in WIFI adapter it is working without problems. On my board computer with the USB ALFA Adapter no way to get connected. Under Windows with the ALFA it works fine. I dont know what to do. With previous ALFA Adapter I had no problem to connect via Navigatrix. Unfortunatelly I do not have the adapter on hand.

cheers

the official name of the driver supplied with the ALFA adapter for Linux is:

RTL8192_8188CU_Linux_V302164.20110715

Maby it will help to find a solution

Cheers
Ferdinand

I'm not sure what you meant when you said you "have installed even the rtl8712 and r8712u.ko" as as r8712u is already installed. I don't find a naked rtl8712(no letter designation) module anywhere.

In order for a new module to be used the one currently in use must be removed.The 'new' one loadedThirdly, assign the module to attach to the device on plugin by modifying a udev rule setup and/or by changing the module.alias for the device...which needs additional investigation.

We'll keep looking.

I am conpletly lost. All I have done bears no results at all. I can see the WIFI networks, but no connection is possible.

Cheers
Ferdinand

I need to do some research. I'll be back.

Silly suggestion but will it connect if you turn off security & the requirement for MAC address in the WiFi hub?

It's a good suggestion.

At home, as a security feature, I have turned off broadcasting the SSID for the wireless network. Occassionally I have to turn it back on and turn off WPA & WPA2 Personal security to isolate the number of variables to troubleshoot why the First Mate's connection was failing coming out of hibernation, for example, or why the network printer started disappearing for no good reason. (Turns out it was a 'good' reason, I was just unaware.) Sometimes changing the channel to one less crowded will do the trick.

There are not a lot of references to ALFA GE-RTL8188. Most adapters in this Alfa USB family are AWUS036H, AWUS036NH, AWUS036NHA, AWUS036NHR. I had what I think is the same wifi adapter on a long extension until it discovered the leak in the dodger during an overnight rain. Others I have talked to are not having an issue. It might be their Alfa is just that much different than the ones flogged in Germany...I don't know at this point.

I have purchased a different from Pinguin with a different driver. Now all is well and the adapter is funktioning with boths systems Windows and Linux

Thanks to all for the assistance
