PostPosted: Mon 23 Jun 2014, 21:30    Post subject:  How to use Trendnet TEW-649UB USB wifi in Slacko? (Solved)  

I apologize if this is covered elsewhere but I didnt seem to see this exact Trendnet model mentioned in the forums.

I am running Slacko Puppy 5.7 live CD no PAE and to help others I would like to mention that I am having success with the Netgear WNDA3100v2 (Broadcom BCM4323 chip) usb wifi adapter. I am using the ndiswrapper and can connect if my encryption is set to WEP.

But my real question is about the Trendnet TEW-649UB wifi adapter with the RTL8191SU chip.
I have had great luck using this Trendnet wifi adapter with other Linux distros but can't seem to get anything to work with it in Slacko Puppy.

All the other distros load the r8712u driver for this adapter and it works out of the box.
When I use the Network Wizard in Puppy to load this module r8712u it says it loaded but I get no response from the adapter; no LED light and no networks detected.

I am new to Linux in general so I really need help!

I noticed this adapter and chip aren't mentioned anywhere in this list so does this mean this adapter is not usable for Puppy?

Hi...

A couple of things I can suggest so far is to...

1. Try another version of Puppy, such as Precise, and see if the problem can be duplicated or solved.

2. Try another connection manager such as Frisbee and see if that helps.

Also, does the adapter show up under lsusb? To find out, please open a terminal (Urxvt Terminal Emulator under "Utility,") and type in...

Code:
lsusb


Just as FYI, the Wikidevi site shows this information about your adapter.

Thanks! Smile

Interesting commnts here...LukeM

" It dawned on me that this is 10 year old hardware, and may only work
at 11Mb/second (802.11b).
I had set my wireless router to only connect with 802.11g (54Mb/second).

I changed the router to Mixed, and it connected like a charm.
DHCP worked fine as well. "

I think the OP's statement above speaks of a different issue, although I could be wrong. Wink

Just out of curiosity, I purchased one of these adapters. Here are the test results.

1. On both Slacko 5.6 and Precise 5.7, it worked OOTB. The r8712u module was loaded along with the firmware rtlwifi/rtl8712u.bin.

2. There was one small wrinkle when using PWF. Most adapters will report a hidden ESSID as "". But this one reports it as "<hidden>". So if you take the list of ESSIDs into gtkdialog, it will choke on this unknown tag.

3. It failed miserably in Slacko 5.7 with the dmesg error "firmware request failed". Unplugging the adapter would then cause a total crash. I tried firmware files from other Puppies with the same negative result.

4. In Slacko 5.7, I blacklisted r8712u and installed ndiswrapper. This worked OK.

5. It works fine in Slacko 593.

Hey everybody, thanks for your responses to my post.
The strangest thing just happened...
Since I started this thread I decided to try to run this Trendnet TEW-649UB on a different old computer which is a Dell Optiplex GX270 running with 2.5 gigs of RAM.

After accidentally deleting my Slacko Puppy 5.7 live CD no PAE.iso; I downloaded Slacko Puppy 5.7.0-PAE.iso.

Now I start the computer and the driver loads OOTB complete with blinking LED and available signals showing in the Frisbee window!
Signal set to WPA2-PSK[AES] 150 Mbps
All I had to do was use frisbee to select my signal and log in.

I don't know what did the trick?
Was the other computer having issues with the USB port?...I tried every port on the other computer plus the other devices were working with the same USB ports.
Could the PAE version handle drivers differently?
One thing to note is I am using Easy2Boot for USB's and this time I was sure to defrag the ISO file before using as recommended by the Easy2Boot website.

rcrsn51; Running the original set-up from my original post would also result in a total crash if I attempted to unplug the adapter.

Ardvark here is the output of lsusb on the working set-up...

Code:
# lsusb

Hi Tardis...

If I had to guess, it wasn't that the PAE version handles the drivers differently, it's that it had a driver for your adapter, while the non-PAE didn't. To confirm that, you could try running the PAE version on the original computer and see if it detects and sets up your adapter. Smile

But I'm glad you found a version of Puppy that works. Smile

Regards...

Now with this new set-up I get Trendnet TEW-649UB to work OOTB on Precise 5.7.1.iso. as well.
Although the SSID's take a lot longer to populate the Frisbee menu.
But from there it's just a matter of entering the password and I'm connected.
Still at WPA2-PSK[AES] 150mbps
I did defrag these ISO's before using them in Easy2Boot which is strongly recommended...
In any case we have a definite wifi adapter we can add to the known working list for Puppy!
