README

“Hey man, What’s the name of the network here?” “Ammm, its ‘name that you will never be able to guess’”. “Oh, Weird. OK. What’s the password?” “Its, g6%kh&23.. Wait, let me enter it. It’s very complicated.” Just then another friend asks… “Hey what’s the password for the WIFI network here?” There is an easy solution for all this mess! Enter -> Wifi Joiner. An Android app that can add networks to phones by just scanning a QR code. Just hang in a QR code generated by WifiJoiner anywhere at your home. Whenever anybody scans that QR code on their phone, the network you configured in the QR code will automatically be added to their device. It’s that simple. Generating QR codes is very easy. 1) Open WifiJoiner. Press menu button and select create. 2) Just select an already configured network on your device in the app WifiJoiner 3) Enter the password 4) Tap “Generate QR code” 5) Done. You can now share this QR code via the convenient share button or even email it to yourself to take a print out of it and hang it on a wall at your home. Joining a network at friend’s house. 1) Scan the QR code they have in WifiJoiner 2) Tap Connect. 3) Done. No network selection. No password. The app is available on the market at https://market.android.com/details?id=com.proj.wifijoiner I developed this app over the weekend. So it might be a bit buggy. But I will be fixing all the issues very soon. I dont have all the Android devices(300 of them!!) and also dont have all the versions installed. So the performance and usability might be a bit different across devices. Please bear with me for that. You can log any issue or feature request you might have at WifiJoiner - Issues page - https://github.com/jvashishtha/wifijoiner/issues. Pour in any reviews and feature requests that you might have! Happy “WifiJoining”!

Connect to 2 WiFi Networks at Once in Windows 10

Suppose you have access to two separate WiFi connections and want your PC to connect to both of them for better internet bandwidth and performance. Doing so may seem difficult or impossible, but you can make it happen on your Windows 10 computer.

In the following sections, we shall look at the methods that will let you connect to two WiFi network connections on Windows 10 computer. These methods are pretty simple to execute; follow the steps carefully, and you will be all set to go.

How to Merge Two Wireless N Connections in Windows 10

Method 1: Through Load-balancing Router

One of the methods that do not require Windows 10 settings to be tweaked on your PC is through a load-balancing router. A load-balancing router will enable you to use two different internet connections to merge and provide a better internet bandwidth right through your Wi-Fi router. All you need are separate internet connections. You can use the LAN cable of the two internet connections in a single router to transmit Wi-Fi network with enhanced bandwidth and speed.

You can either use two separate connections from a single Internet Service Provider or individual network connections from different Internet Service Providers for this purpose. The LAN wires bearing the internet connection from your ISP(s) should be inserted into the load-balancing wireless router’s input sockets. After attaching the router’s network connections, you will have to carry out a couple of configuration settings.

How to Configure Wi-Fi Router to Bridge two Wireless Networks

To merge (bridge) internet connections on the router, you will need to access the router’s configuration settings page. Although the process is pretty simple, it varies according to the Wi-Fi Routers’ manufacturers.

WiFi Routers have firmware installed in them that lets you configure the device according to our requirements. These settings can be accessed on your PC through a web browser. To make two wireless network connections work together through a router, you will want to load the router’s network configuration page on your computer.

The steps required for this can be easily found on the router’s user manual. If you cannot find the router’s user manual, you can access the same from the manufacturer’s website.

Alternatively, you can also contact your internet service provider and ask them to help you out. Try to get in touch with a technician.

The process for the same can also be found easily on the internet. All you need to do is carry out a Google search regarding the same with the router’s manufacturer name and the model number. For example, perform a google search as Manufacturer name Model Name load balancing.

Once the settings have been applied, you can go ahead and restart your router. After the restart, you will be able to access the wireless network connection with boosted bandwidth and speed.

Note: To merge two wireless network internet on one router, you will need to have a router with load-balancing capabilities. A load-balancing router can merge not just two but more wireless network connections on a single router. You have to make sure how many network connections does a router supports for load-balancing.

Method 2: Through Speedify (third-party software)

Do you have access to two different WiFi networks and would like to use both of them on a single PC. With software like Speedify, you can merge both of them pretty quickly. However, using this feature comes with an additional requirement of connecting new hardware to your computer.

A laptop or PC has just one wireless network adapter by default. This means that it can connect to just a single Wi-Fi internet connection at a time; however, by adding a Wi-Fi network adapter, you can connect to two different wireless networks on your PC. So, make sure to have an external USB Wi-Fi adapter handy.

Your PC must be connected to one of the WiFi networks by default. To connect to another WiFi network, insert the external WiFi dongle adapter into any of your PC’s USB slots. Now, wait till the external device’s adapter is installed. The installation process of the adapter is automatic, so you do not need to do anything.

After installing the adapter, you may have to turn on the second Wi-Fi option using the Settings app.

Press Win + I to open the Settings app. In the Settings app, select the Network & Internet option. Now, on the Settings window, go to the left panel and select the Wi-Fi option. Then, go to the right panel; you will see a Wi-Fi 2 option, enable it through its toggle switch.

After enabling the second Wi-Fi adapter, go to the Windows taskbar at the bottom of the screen. Here, select the Wi-Fi 2 option from the dropdown menu and connect to the second WiFi network connection on your Windows 10 computer through the external WiFi adapter. This has to be the other WiFi network you would like to merge the internet connection with.

When done, open the Speedify software on your computer. If you haven’t installed it, download it first from the Speedify Official Website.

On the Speedify interface, you will see both the WiFi networks that you are connected to. Now, by default, according to Windows 10 settings, your computer will only use the wireless internet connection that is performing better.

Once you have established that your PC is connected to both of the WiFi networks, go ahead and activate Speedify. This will activate the WiFi bridge process. Now, you will be able to access the internet on your PC with a better bandwidth.

To check if the method worked or not, you can check the Speedify interface. Here, you will get all the information that you require about both the WiFi networks, separate, as well as combined. The information available on the interface includes data usage, latency, ping, download speed, upload speed, and the duration of the active connections.

Once you are done using the bridge wifi network connection between the two networks, you can disable Speedify if you want.

Mind you, Speedify is not a free software to use. To unlock its full potential on your PC, you will need to buy the full version. With the unlocked version, you will be able to merge two WiFi networks at a time on your Windows 10 PC.

Conclusion,

Although it is not that difficult to connect two WiFi networks at once in Windows 10, the real problem arises when you have to make both WiFi networks work collectively.

Using a load-balance router is the way to go, but what if your router doesn’t support load balancing. In such a case, using third-party software, such as Speedify, comes into the picture. However, this also requires you to have an additional WiFi dongle connected to your PC. Before merging 2 WiFi network connections on Windows 10, make sure you have all the necessary hardware required for carrying out the process.

How do I connect to multiple wifi networks?

How can I connect to 2 WiFi networks at the same time with only 1 WiFi-adapter? I have two separate wireless networks, to which I need to connect the Ubuntu-PC simultaneously: The first with internet access and the other one without internet access. I tried to create a Virtual Interface and even though there doesn’t seem to be an error, it did not appear in the Network Manager. It would seem, the driver I am using, is ath9k: How can I find out whether my it can create virtual wireless interfaces? Can I replace the driver ath9k, if it doesn’t support virtual interfaces?

I think you’ll need multiple adaptors. But perhaps I’m wrong. serverfault.com/questions/192144/… might be of interest.

Yes you can, if your card support it. First of all look the documentation of iw and especially the page of virtual interfaces. Unless you are running 14.04, that is, due to a bug in udev scripts (probably fixed in 15.10, but no confirmation yet).

Note that in the following description wlan0 is my normal WiFi interface and wlan1 is the name I choosed for the virtual one (it’s quite arbitrary). You have to adapt this to your system, of course.

You can create a new virtual interface with:

sudo iw dev wlan0 interface add wlan1 type station 

if your adaptor/driver support it, it’s done — you now have two interfaces; otherwise you will have some type of error or the interface will not appear.

You can check if the new interface exists by typing

. and see if the wlan1 interface shows up. It will appear in the Network Manager too anyway:

You can remove the virtual interface with

I really never used it — I tried to connect twice to my router and havoc arose (but that probably is normal). Moreover, you will probably need to see if packet forwarding between the two interfaces is enabled by default or not, and you probably need to play a bit with the routing after that. But it’s a start.

PD — one of the thing you will probably have to change is the MAC number of the «virtual» interface, which is by default the same as the other, and will create problems almost for sure.
