Almost got D-Link GO-USB-N150 to work

[tom_elkrider]

Device in question:
Dlinkgo (D-Link) Wireless N 150 Easy USB Adapter
Model: GO-USB-N150
Hardware version: B1
Firmware version: 2.00

lsusb sees it as:

Code: Select all

Bus 001 Device 008: ID 2001:3311 D-Link Corp. 

Out-of-the-box this adapter gave me absolutely nothing. After some googling
I found instructions on an Ubuntu forum about how to tweak the RTL8188EU driver
(https://github.com/lwfinger/rtl8188eu) to detect this device.
The code as follows:

Code: Select all

sudo apt-get install build-essential git linux-headers-generic
git clone https://github.com/lwfinger/rtl8188eu.git
gedit  rtl8188eu/os_dep/usb_intf.c
- - - Change this line: {USB_DEVICE(0x2001, 0x330F)}, /* DLink DWA-125 REV D1 */
- - - to this: {USB_DEVICE(0x2001, 0x3311)}, /* DLink GO-USB-N150 REV B1 */
cd rtl8188eu
make
sudo make install
sudo mkdir -p /lib/firmware/rtlwifi
sudo cp rtl8188eufw.bin /lib/firmware/rtlwifi/

It worked. The blue LED-light came on and I could now choose wireless networks
from my networks list. However, after opening a wireless connection the signal
only stays alive for a few seconds before dropping to practically zero.

I can turn the driver on and off again by modprobe and it again comes to life for a few
seconds before dying.

iwconfig returns:

Modinfo gives me a whole load of parameters to mess around with but I'm flying blind here.
I have no idea what they mean:

Any ideas and help would be greatly appreciated!

Try:

Code: Select all

sudo nano /etc/modprobe.d/8188eu.conf

and insert the following:

Code: Select all

# Disable power management
options 8188eu rtw_power_mgnt=0 rtw_enusbss=0

then:

Code: Select all

sudo modprobe -r 8188eu
sudo modprobe 8188eu

or restart the machine.

This effectively disables the power management feature of the wireless device preventing the connection drop outs.
For me it worked in Ubuntu 12.04.

And thank you very much! This is by far the most complete subject on installing GO-USB-N150 on linux.

I have the same device i.e. and had the same issue (device driver was not available/working).
Dlinkgo (D-Link) Wireless N 150 Easy USB Adapter
Model: GO-USB-N150
Hardware version: B1
Firmware version: 2.00

I am running Ubuntu 12.04 LTS
Linux 3.8.0-37-generic #53~precise1-Ubuntu SMP Wed Feb 19 21:37:54 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

By running only the bellow commands i got it working (no problems with signal)

Code: Select all

sudo apt-get install build-essential git linux-headers-generic
git clone https://github.com/lwfinger/rtl8188eu.git
gedit  rtl8188eu/os_dep/usb_intf.c
- - - Change this line: {USB_DEVICE(0x2001, 0x330F)}, /* DLink DWA-125 REV D1 */
- - - to this: {USB_DEVICE(0x2001, 0x3311)}, /* DLink GO-USB-N150 REV B1 */
cd rtl8188eu
make
sudo make install

Just wanted to reconfirm that the device should work on similar configurations.
