Combining 2 Wireless Connections For Reliability ?

[Joey_7]

Well lads,
I want to ask if it is possible to combine 2 different wireless connections for reliability, let me explain my situation.
To livestream I have to use the 4G on my phone as a hotspot but the problem with 4G is that the download speed sometimes dips with signal changes while the upload remains pretty high, my broadband connection has 20 down but shit upload speed (0.6), so I was wondering if it would be possible to combine the connections so say if the download speed dips on my 4G I can use the broadband as backup
Please help and thanks !

Maybe depends what your goal is. The hardest issue is when you switch back and forth your IP address changes so you get session drops. You also can not do stuff like upload data on one and download on the other again because the IP is different.

What you can do is run some application on one connection and other applications on the other. This tends to be fairly tedious to set up. For example on many games you have a login server and a game server. You have to be sure that the IP address your traffic comes from is the same or it won't work. You can get your account locked in some cases because it will be detected as hacking.

In any case the magic command you want is ROUTE.

Start with ROUTE PRINT.

You should see 2 entries with 0.0.0.0

The one it uses as primary is has a lower metric. If you just want to switch all the traffic back and forth you can just delete one and change the metric lower.

Now to use both you need to delete the one that you do not want to use as your default for all traffic. You then do

ROUTE ADD w.x.y.z MASK 255.255.255.255 ?.?.?.?

Where w.x.y.z represents the ip of the server you want to use the backup connection and ?.?.?.? is the ip of the secondary router.

............So I get this far and then realize you are asking about 2 wireless connections. If you have 2 wireless nics then you can attempt the above. You can not have 2 wireless connections on a single nic and to make it switch is generally a manual process of disconnecting one and connecting the other. I would one nic on wired and the other on wireless. It will prefer the wired one by default..ie it will have a lower metric
