This isn't something controlled by KDE, but rather by the driver (The binary blob) that is loaded at run time to manage the wifi card.
So you need to start by telling us the name of the wifi card, the chipset manufacturer.
Usually a command like /sbin/lspci will print out a list of things, and usually there is something in there mentioning wifi or 802.11b/g.
From there someone will probably be able to help you to obtain the proper firmware from the net and install it.

I think that the driver you need is the rtl8192ce, but it might also be rtl8188c or rtl8188cu depending on country. rtl8192ce is a PCI-E driver for RTL8192CE/RTL8188CE devices. Its been supported for quite some time, and you should be able to locate it in /lib/firmware/rtlwifi and match that with what has been loaded. (It might be listed by the lsmod command). There is a guy working on this driver trying to improve performance. One issue is the power output may be improperly limited in the stock drivers. Limiting power can prevent 802.11N connections. He suggested trying a different country codes in for the wifi via sudo iw reg set BO for example.

Which is a good reason to avoid that stuff and bug the opensuse package maintainer to bring that package up to date.

Why do you think I have a problem connecting with n? It works fine and I generally get 150 Mb with it. My question was about the ability to lock the WiFi to g or b for testing purposes. I configured an access point to n only and wanted to make sure g & b couldn't connect. I had to boot into Windows to do that, where I could select b or b&g only. I was looking for the same capability in Linux. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, With this device/driver you can't disable the 802.11n mode (see modinfo rtl8192ce) . From all wireless adapters which I have only those which use the Intel wireless driver (iwl4965) have this option (11n_disable). If you use the mode restriction of hostapd on your AP (e.g. the require_mode option in OpenWRT) I can assure you that it works. Regards, I. Petrov On Fri, 19 Jun 2015, James Knott wrote:
