 Hi there, welcome back to my YouTube channel. This is Daniel Rosel here. So I mentioned yesterday that I finally got my Home internet my backup internet system running as intended With my two connections my ISP connection coming off the router and a backup cellular Connection coming off a 4g router both those two connections going into a load balancing router. That's the TP link TL-R470T plus those are both feeding into the load balancer load balancer is keeping an eye on connection one and connection two you can see them up here in My connections dashboard and I have set up a simple backup rule that says well if we lose connection one Which is one one let's bring up connection two which is cellular and it flips it back now What I wanted to do in today's video was to do a quick test to see how well that Fillover is working now. I did this before with the TP link cellular router, and I did that using a Using is my internet up comm which will just ping your connection every two seconds But I said I do this one a little bit differently just by pinging a Google DNS server Because we'll be able to see more easily when the connection drops and how many Connections were dropped. So the way I'm going to do this is very simple I'm going to roll back here in my chair, and I'm going to pull out the ethernet cable That's feeding the load balancer with the ISP connectivity, and then we're going to see how long it takes what I'm going to do is Bring over to this screen here, and I'm just going to ping away at One of Google's DNS servers and I'm going to set the interval to one second so we should be now pinging at a one second interval and We're also getting a sequence. So because there's one second every Every sequence here is going to be at a one second interval what I'm going to do now is as promised Make the make the big move across the office to the load balancer back there I'm you're going to pull at the cable and We're going to see how long that takes to fill over to our second connection Okay, so I pulled out the ethernet cable there And we can see that the ping test is frozen at 32 So it pinged it pinged that server successfully 32 times and at 44. No, we're still not back destination host unreachable I'm going to just 54 so it took between 54 is when it came back and 32 is when we lost it. So that was My brain is freezing 22 seconds to fail on to a viable cellular connection next question is going to be how long would it take to come back and That's probably about something something similar. So that's my test with the failover time from ISP to cellular using the TP link TLR 470 T load balancer happened automatically didn't need to do anything, but it does take a little bit of time For that link detection because what's happening in the background is that the load balancer is also pinging away at those Google's Google DNS server is actually the same one and It's taking just a little bit of time for it to send that ping Register it's offline and then swap over the connectivity Hope this video was useful and if you'd like to get more videos for me Then feel free to subscribe to this YouTube channel.
