I have installed Ubuntu 14.04 LTS 64-Bit and have a Edimax EW-7811Un wifi adapter. I have tired to get it to work but have no luck.
when I run lsusb command I get:
Bus 001 Device 005: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]
iwconfig shows that nothing is being read or connected:
eth0 no wireless extensions. lo no wireless extensions.
I have tired numerous forums and tutorials but cant get it to work, dont know what I am doing wrong.
Can someone give a clear step by step method to get this to work?
uname -r: (Kernel Version)
3.16.0-34-generic

harnamc about 9 yearsShould I be worried about all the failed attempts and random drivers I have tried to download and install? Is there a way to clean/flush them?

Andy J over 8 yearsUnder Ubuntu 14.04 LTS the adaptor seems to be supported but the connection is intermittent. For anyone facing this problem while applying this patch, I recommend just disconnecting and re-connecting to the Wifi hotspot.

ustulation about 8 yearshow do we undo this - i did this and found that it did not support 5GHz. My internal realtek8723be works just fine too (i manually built and installed rtlwifi_new). So i want to go back to that. Presently after this, when i take out the edimax usb, i dont even get the enable-wifi listed. So how to undo this ?

sudo dkms remove 8192cu/1.10
,sudo rm /etc/modprobe.d/blacklist-native-rtl8192.conf
should do it.
