awus306nhr won't connect on dell inspiron with ubuntu 14.04

Question

I just installed ubunutu 14.04 on a new dell inspiron. I need AWUS306NHR in order to get my wifi network at home. The usb network card appears in the network manager but cannot connect whereas builtin wifi can.

I tried

git clone https://github.com/pvaret/rtl8192cu-fixes.git
sudo dkms add ./rtl8192cu-fixes
sudo dkms install 8192cu/1.10
echo "blacklist rtl8192cu" | sudo tee -a /etc/modprobe.d/blacklist.conf
sudo reboot

as suggested in another forum with no results.

here are the results of the requested command lines:

any help please?

After some research I found this:

http://en.data-alliance.net/alfa-awus036h-power-problem-fix-realtek-rtl8187l-chipset/

Could this be a solution?

And how can I verify it before buying extra material?

thanks.

Answer 1

I suggest you update the driver to the even newer rtlwif-new. From a terminal:

sudo add-apt-repository ppa:hanipouspilot/rtlwifi 
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms linux-firmware

Reboot and let us hear your report.

Please check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.

Next, I recommend that your regulatory domain be set explicitly. Check yours:

sudo iw reg get

If you get 00, that is a one-size-maybe-fits-all setting. Find yours here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Then set it temporarily:

sudo iw reg set IS

Of course, substitute your country code if not Iceland. Set it permanently:

gksudo gedit /etc/default/crda

Use nano or kate or leafpad if you don't have the text editor gedit.

Change the last line to read:

REGDOMAIN=IS

Proofread carefully, save and close the text editor.

Next, I'd set IPv6 to Ignore in Network Manager: http://docs.fedoraproject.org/en-US/Fedora/18/html/Installation_Guide/images/netconfig/network-connections-ipv6-ignore.png This example is for ethernet, but you want wireless.
