If you are a Wi-Fi lover & Linux user you must read this article. This article is about “How to take control of Wi-Fi connections“. Easy connection to the Internet over Wi-Fi is no longer a privilege contradicted Linux users. A new distribution on a fairly recent laptop. Connecting your Linux laptop to an available Wi-Fi network is often as easy as it is with your phone. It wasn’t forever like this. “How to take control of Wi-Fi connections”. Wi-Fi has long been a running joke among Linux laptop users. Many users would format their hard drives & ready to install Linux only to find that they couldn’t earn online.

I went through this when I first time installed Ubuntu 8.04. On my new Asus Eee PC. (Luckily, the Eee PC came with an RJ45 ethernet jack). Getting Wi-Fi working is less of an issue today. (Though it still can be difficult on occasion). But just getting something to work is only the 1st step with a little extra effort. You can optimize your Wi-Fi connections on Linux. For the high speed & improved privacy.


How to take control of Wi-Fi connections:

All of the features I’m explaining can be found in Network Manager’s connections applet. For many users of Gnome or Unity (Ubuntu). You can easily click on the Wi-Fi or network icon in the top-right of your screen. In the drop-down menu, select Edit Connections. If you don’t detect that option, or the correct window doesn’t appear. “How to take control of Wi-Fi connections“. You can open a terminal window & launch it manually by typing nm-connection-editor & hit Enter.

Once the window opens, you should see a list of wireless connections under the Wi-Fi heading. (If you have any virtual private networks (VPNs) set up. You can detect those details in the VPN heading that follows the Wi-Fi heading). To edit the options for a connection, easily click the connection name & click Edit. But the connection names default to the SSID (the name broadcast by the router) of the network. You can change the name to anything you like.

Enable automatic VPN connections on Linux:

Using a VPN is one of the easier & more effective ways to protect your privacy online. While not everybody needs to use a VPN at home. I may confirm that everybody uses a VPN when connecting to public Wi-Fi. Especially when doing things like online banking. The thing is, it’s hard to remember to connect with your VPN every time. You sit down in a coffee shop or airport. Luckily, Network Manager makes it easy to “set it & forget it”.

In the General tab of the connection window. Simply check the option labeled Automatically connect to VPN when using this connection. Doing so will empower the drop-down list below the checkbox. “How to take control of Wi-Fi connections“. The drop-down list will be populated with any VPN connections you’ve previously set up. Select the VPN you wish to use by default for the connection, and you’re all set.

Take control of Wi-Fi:

Locking on to a specific Wi-Fi radio isn’t a feature most people need all the time. But it is useful in few situations. Your PC will try to lock on to and use the strongest signal that’s being broadcast with a given SSID. It’s easier for users if a network administrator sets a single SSID for several wireless access points. Rather of forcing users to re-enter Wi-Fi credentials for each AP. They try to connect to (e.g.: Office_floor1 & Office_floor2). As a user steps from one location to another, their device should lock on to the closest access point. But what if you’re around in between?

If an SSID has more than one AP with comparable signals, the networking stack. On your PC will scan for the best one & switch from one AP to the other, ostensibly at random. To stop this, you can “lock on” to one access point by specifying its BSSID. In the Wi-Fi tab for the connection, easily select one of the BSSIDs. From the drop-down menu, click Save, and reconnect to the network. Your PC should now use that definite access point.


If you still want the ability to get up & roam away from that access point on the same SSID. You can save the connection with a new name (not a new SSID!). Then, copy over all the connection details (SSID, WPA passphrase, etc.) from the other sections of the connection. But assent the BSSID option blank & save bottom a different connection name from the first one. But once you’ve done that, you can select the “roaming” connection. If you have to awake & hold your laptop to a meeting. But use your preferred access point when you get back to your desk.

Set your firewall zone:

As with a VPN, a firewall is advisable when using your PC away from home. Also, like a VPN, you can set Network Manager. To use a firewall policy of your choice according to the network you connect to. Under the General tab for a connection. Simply select a firewall policy from the drop-down menu next to the label Firewall zone. You want to have formerly configured firewall zones. (You have firewall running as a service) in order to do this.

Keep your DNS wherever you go:

Tips to take control your Wi-Fi connections on Linux. If you’re not sure what a domain name service (DNS) is. You’re probably using the one assigned to you by default. Mostly, DNS is a service that translates domain names (like pcworld.com) into IP addresses. Some people prefer to use DNS servers of their choice (like Google’s). “How to take control of Wi-Fi connections“. Rather of the servers handed to them by an ISP. If you want to ensure that you use the DNS servers of your choice. As you act around from one wireless network to another. You just have to configure a few settings for each connection.

Get an IP address and DNS information:

In the IPv4 & IPv6 tabs, the first drop-down menu defaults to Automatic (DHCP). “How to take control of Wi-Fi connections“. For most public wireless networks, you wish DHCP to get an IP address and DNS information. However, the 2nd option in the drop-down, Automatic (DHCP) addresses only. Only bring an IP address from the network, and requires you to set up your own DNS information. After selecting the 2nd option, the option in the tab Additional DNS servers will change to DNS servers. Commonly type or paste the DNS servers of your choice into the box & then click Save.

For reference, Google’s IPv4 DNS servers are & Google’s IPv6 server IPs are 2001:4860:4860:0:0:0:0:8888 & 2001:4860:4860:0:0:0:0:8844. Comment please if you like this article “How to take control of Wi-Fi connections“.
