I've had loads of problems getting Wifi working properly on my HP laptop. the on-board chip is a pig.

I got a TP link TL-WN725N Wifi dongle as the eBay seller assured me there were Linux drivers on the disk. There aren't of course.

I've worked through Naveen's list of commands here but don't really know what they mean. All appeared ok until the last line when I got

insmod: ERROR: could not insert module 8188eu.ko: Device or resource busy

Since this the HP wireless chip works even worse than before, cutting off and on for no reason. The TP link only has 1/5 signal strength when I'm one meter from the router.

Help, my wife already switches back to windows 8 whenever she's on the laptop

I've tried everything I can find on this and other forums, I don’t want to go back to windows but I need Wifi.

I think this is about the Wifi chip on the HP laptop:

RTL8188EE Wireless Network Adapter
vendor: Realtek Semiconductor Co., Ltd.
physical id: 0
bus info: pci@0000:07:00.0
logical name: wlan0
version: 01
serial: 34:23:87:27:ca:11
width: 64 bits
clock: 33MHz

I believe this is the dongle description:

Wireless interface physical id: 2
bus info: usb@3:1
logical name: wlan2
serial: e8:de:27:a1:13:ef
capabilities: Ethernet
physical wireless configuration: broadcast=yes driver=r8188eu ip=192.168.0.12 multicast=yes wireless=IEEE 802.11bgn

 apt-get update

 apt-get install linux-headers-$(uname -r)

 apt-get update

 apt-get install build-essential

 apt-get install git

 git clone https://github.com/lwfinger/rtl8188eu

 cd rtl8188eu

 make all

 make install

 insmod 8188eu.ko

 ifconfig #(check to see if your wireless wlan cards is now listed)

should get you going.

Since it giving you device busy, try this 

 lsmod | grep 8188

if the result looks like “r8188eu 7990995 0″

 sudo modprobe -r r8188eu

then, you can (from the rtl8188eu directory) 

 sudo insmod 8188eu.ko

Edit: This device works with Raspbian (Debian based) with no install needed, so I think there may already be a driver setup, but it may be outdated or just need to be removed and installed again using the git version.
