Subject description: In Pupeee?
 

I made the mistake of buying one of these things because it sez LINUX COMPATIBLE on the box.

So far I've wasted two days trying to compile the driver etc
The device works perfectly with win7, by the way

What version of Puppy Linux are you using? I ask because later versions come with more drivers for such hardware. It's possible that another version of Puppy can use your adapter without you having to install anything.

this is puppeee (2.6.33.3celeron) on a asus eee. i think puppeee is based on lupu 5.04

i confess here that i did not buy this dongle for the puppy but for a beagleboard which is currently running an ARM kernel 3.2.3-x4

i thought it was worth looking at this dongle because a lot of tech-minded aussies buy stuff from jaycar and lots of them will try this hardware on their linux box.

putting things like "realtek 8178 linux" into a search engine trawls up nothing but woe.

Jaycar have poor documentation for their products...not even the manufacturer is mentioned....

I downloaded and opened the driver from that site and it gives an RTL8191SU as driver for linux, so where did you get Realtek 8178 from?

This looks like your device on ebayAU?

Can you post the output of typing
Code:
lsusb -v
in a console to verify the device [or get details from hardinfo]

Also run
Code:
uname -r
to identify your kernel, as 2.6.33.3celeron doesn't check with google, thanks
see this post, which has a dotpet for that driver for 5.1-5.2.8, but I don't know if it'll work in puppeee, as it may use the 4.3 kernel?
If your kernel is 2.6.33.2 the dotpet should be OK

Good, so from my link

It is for the right kernel, so should be OK

I'm puzzled at lsusb, but not crucial, as it identifies OK

Don't forget to scan for your router SSID, and enter security passphrase, save/use this profile, to get connected, using network wizard Very Happy

If it works OK, can you edit the subject line to show Solved in your 1st post, ta!

well i copied the file from the 2.6.33.2 folder to the 2.6.33.2celeron folder and run depmod -a

i'm still very confused.
the vid:pid for this dongle is

0BDA:8178

but the drivers you described seem to be for

10EC:8178

also the correct aliases don't appear here:

Code:

but that looks like a different problem.

I'm taking this thing back to jaycar! too many headaches! DON'T BUY ONE FOR LINUX is the best solution. (ie the operating system is controlling the operator Twisted Evil )

You just needed to install the dotpet AFAIK

Quote:

10EC:8178


AFAIK, 0BDA is 8188CU or CUS, and needs the 8192CU driver pet, and 10EC is 8191SU, and needs the 8172U pet

It seems they [like other manufacturers] are using different chipsets in different versions

There are many additions for wifi dongles in later kernels, but drivers are both chipset and kernel specific, which is why people get such problems

Ask the dealer for one that is known to work/demonstrable even? in linux
else use ebay, specifying linux, or realtek...there's loads now

eee is great i just put it on the counter plugin new hardware and watch /var/log/messages or syslog or dmesg

that one caught me out tho because it had "linux compatible" on the box, and i was in a hurry.

its back in jaycar where it belongs now. i told them its not as "linux compatible" as it could be.... ..
