Realtek 8812au Wireless USB cannot be configured onto a network

English Network/Internet
#1

Not sure what I’m doing wrong here, but it doesn’t seem as though I can get my Asus USB-AC56R to connect to a network on OpenSUSE 13.1. I followed all of the advise in the forum sticky notes before posting. The network stick uses USB 3.0, and the Realtek 8812au chipset. I was able to install/compile the drivers, and it looks to be running normally:

NetworkManager runs and is able to scan networks through the device. But the network changes never seem to be committed and always remains in an “unassociated” state. I’ve confirmed that wpa_supplicant is installed. I’ve also tried configuring the device onto the network through the “legacy ifup method” via “ip link set wlp6s0u1 up” and then “iwconfig wlp6s0u1 essid Kilkenny” … but I can’t seem to get the device to latch onto the network.

What else can I try, and what am I missing here? Thanks in advance!

I made some good progress on this today, and got the the adapter to connect successfully to the network and am able to access the web. Only way I can seem to do it is through a manual method.

I noticed that NetworkManager was not saving a lot of the information I would configure it with, such as network passwords. I would also get the following pop-up whenever I wanted to edit the wireless connection: http://paste.opensuse.org/14923470 (States that “No agents were available for this request”). When playing around with NetworkManager in a more “advanced” mode, it seems like it can only be configured for a/b/g/n networks, where I’m trying to latch onto an 802.11ac network… not sure if this may be part of the issue.

After combing through the wpa_supplicant logs, I was puzzled to see that the system latched onto the network, and then quickly kick off (this was recorded only once, right after I installed the device the first time)… I also saw the wpa_supplicant would constantly try to be in an connected/active mode, but would always relegate to inactive.

So I went back to this resource: https://en.opensuse.org/SDB:Tracking_down_wireless_problems, specifically to the section on manually configuring and connecting the wireless device: https://en.opensuse.org/SDB:Tracking_down_wireless_problems#How_to_set_up_a_connection_manually

Here, I was able to see that the /etc/wpa_supplicant/wpa_supplicant.conf file was almost empty, and had no configuration info. I followed the directions to start wpa_supplicant manually, and loaded up wpa_gui. Using wpa_gui, I was able to successfully configure and latch onto the network! I then saved the configuration to /etc/wpa_supplicant/wpa_supplicant.conf where it currently resides.

So I feel like I’ve made a huge step forward tonight… I can manually connect. However, I would now like to configure this to auto-connect each time I start or restart the system. Restarting the system now automatically starts NetworkManager, and I don’t get a connection. If I configure OpenSUSE to manual ifup mode, would that put me on the right track?

Any suggestions on how to further troubleshoot NetworkManager as to why it won’t connect, even though I have the correct settings now in /etc/wpa_supplicant/wpa_supplicant.conf?
