@TeleSkope21 Could you try just the power management patch of the patch and report back?

its not the power management..... the powermanagement is off for USB and Network....

but what a power management patch? O.o

Dear all,

I would like to add myself to this conversation.

I have a USB WiFi stick that uses the Realtek RTL8192CU 802.11n WLAN Adapter.

This stick works completely fine out of the box with Ubuntu 16.10 and 17.04.

On Solus, however, I cannot connect to any network.

Sometimes, I get to see a list of connections but I cannot connect to either of those connections.

It always tells me the connection cannot be activated.

Can I provide you with any further information to fix this problem?

Yours,

Robert

Hi All,

Today I tried Solus OS 3 GNome live CD on my desktop which uses the TP-LINK TL-823N wifi adapter that is based on Realtek RTL8192CU chipset. WiFi connected fine and it seems stable, however the signal strength is not definitely the same as the patched driver on my Salix OS.

May I know the reason why DKMS is not included or cannot be included with Solus? Is there a way to apply the patch in Solus without having DKMS installed?

The patch is available at https://github.com/pvaret/rtl8192cu-fixes.

Thanks,
Balaji.

As far as I can tell we have done everything on our side to make the RTL8192CU cards work. We will NOT be enabling DKMS or applying out of tree patches for signal strength as these patches and drivers usually violate broadcast strength ratings sets by organizations like the FCC. If these cards are replacements for internal wireless cards, I can almost guarantee that your antenna is mismatched with the chipset.

@DataDrake,

Thanks for your response.

From the user perspective, I can't use Solus until a device that I have doesn't work.

I am very impressed with Solus, but I still use Salix as my daily driver. Everything that I need works on it including the WiFi card with rtl8192cu chipset.
