Using YAST where no apt-get available

Like many people I am having wifi issues. I believe I have tracked down the issue (see end of post) but for the sake of completeness let me post some info about my wifi connection when using a wifi dongle - my realtek wireless does not work:

The resolution seems to be here:

How can I do this using Yast? Is there a solution for OpenSuse?

Many thanks in advance.

And which Chip is there not working?

Post:

lsusb
/sbin/lspci -nnk | grep -iA2 net

This is the prob - RTL8192CU:

Wireless Realtek chipsets that are running on the default RTL8192CU driver, often lose connection and run below their proper speed. That’s because of a bug in the rtl8192cu driver.

When you make a bold statement like that, you need to describe your reference.
Nowadays, almost all device drivers are now distributed through the Linux kernel obsolescing all those articles that describe User mode installation, compilation and most firmware installations.

As @Saurland describes,
You need to post information about your device and how it’s seen by the system to evaluate.

The reference is contained in my first post. I just need to know to implement the steps suggested in that reference.

Hi
Probably best to ping user lwfinger (via pm) check the stickies
(written by him), post the info and hopefully he (the kernel module
author) can provide some insight to the issue :wink:

modinfo rtl8192cu

gives the address to contact him

If you want to try what is described in that article,

You can install the prerequisites on openSUSE with the following command

zypper in kernel-devel dkms git

Skimming the article quickly, all the non apt-get commands should also work on openSUSE.
Some of the commands are irrelevant because are related to whatever might already be installed if you’re running a Desktop.

As @malcolmlewis describes, there is already a described procedure for compiling many wifi firmware by @lwfinger, you should find references to his articles in the stickies to this Forum.

I’d also caution you that your referenced article is not dated but by its references suggest the advice might be applicable beginning about 3 yrs ago, possibly to current and does not describe what kernels his advice applies to. It’s very likely that if his suggestions are of real value that they should have been integrated into the mainline kernel which would obsolete his advice.

You should also look at the documentation for the proposed patches at
https://github.com/pvaret/rtl8192cu-fixes
You’ll notice that the patches can’t be applied to any current kernels and the last patches created were over 2 years ago. In fact, he specifically says you can’t patch a kernel later than 3.11 so indeed this is very old technology.

Your referenced guide is also a private, personal site so YMMV. You might want to first check whether other sites reference his work or repeat his advice before doing this yourself.

Many thanks TSU and for reading my post thoroughly. The article came up in Google - had no idea it was private… have contacted the author as suggested and will try what you outline. Shame that such a great installation is spoilt by the wifi issue and judging by the comments this is a big problem. I have spent hours on this already. Bluetooth does not work either… anyway plan to stick with it.

Contrary to all expectations and thanks to TSU2 for running through my notes my wifi is now working!!!

Like many people I fiddled with about 6 different things at once so I can’t be absolutely sure but I think it was implementing the article suggestions which I highlighted and were commented on by TSU2 that really did the trick. This is heaven… :slight_smile:

Hi
Good you got it all working :slight_smile: But what about the next person? It
does help the module developer if feedback is provided so any issue can
be fixed for other folks :wink:
