I'm relatively new to Ubuntu, and I'm having some issues with my wireless internet.

When I boot up Ubuntu, it connects to the internet fine and I'm able to use it. But, sometimes after a while it randomly stops working (can't open new links or refresh current web pages). It says that I'm still connected. When I disconnect, it doesn't disconnect immediately, and when I try to reconnect it won't no matter how many times I try. The only way I can reconnect is to restart my computer, and I do not have access to Ethernet wire connection to try to bypass the issue.

I do not have this issue when I boot my computer into Windows 8.

I have tried deleting that wifi connection and adding it again (as suggested by one of these threads), but that did not help.

My output for the:

lspci -knn | grep Net -A2

command in terminal is: 

01:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723]
Subsystem: Hewlett-Packard Company Device [103c:2231]
Kernel driver in use: rtl8723be

Any help would be greatly appreciated.

Thanks.

You need to install a better wireless driver. It can be done this way. Run in terminal these commands (one by one):

sudo apt-get install git build-essential
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install

You will need to re-install it after each kernel upgrade.

I am working on dkms module.

I finally made a ppa with this driver. It can be installed by

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

In this case you will not need to re-install after kernel updates.
