 Hey guys, welcome back to my YouTube channel. This is Daniel Rosal here. Excuse my voice. I am dealing with a bit of a cold at the moment, but I'm going absolutely crazy lying in bed drinking cups of tea I've just had my warning coffee, so I'll hopefully get my voice will get a little better as this video progresses I wanted to make a video about how I feel really really good Very very reliable home internet. I think I'm gonna call this something like how to get really reliable home internet now I have made a whole bunch of videos on this topic a playlist and They have been my most popular videos on YouTube to date They generate a decent amount of comments and emails and people are interested in this My interest in this whole subject started because even though I live in Israel, which is current which is commonly thought of as you know a high-tech Superpower and it is but internet connectivity is not always Equitably distributed. So there are kind of like black spots and it really just depends Whether the companies have brought a good infrastructure in your exact part of the city or country and in my case Whatever neighborhood and street I'm living on in Jerusalem the best we have there is no fiber yet Even though there's three different companies laying fiber optic internet connectivity. None of them have hooked up My building yet or a street. I'm on all the waiting lists and waiting and waiting So what I did instead was last summer our internet got really really bad It's VDSL based connectivity and I got a bit creative and that led to this series of videos So I'm going to cover two topics in this video and I'm going to be diagramming stuff here Using draw.io. In fact, I'm going to go ahead now and turn on my cursor so that you can see what I'm doing So I'm going to cover two different ways. You can get amazing home internet and the first one I'm going to call this is High availability home internet now the thing about this the reason I'm using this terminology specifically Is because there's a difference between a lot of comments. I've got from people on YouTube are well Oh, cool. So we can like add two different Internet connectivity is like put the speed together right and I'm like Depends not really that's a different thing. There's something called connection bonding I'm going to show a few ways you can achieve Connection bonding now the difference between this and my previous videos is this is just conceptual I'm not going to talk about specific hardware products that you can use. I'm just going to show you how you can do it so basically the key if you have sucky home internet and It's amazing. How many people suffer this problem? Let's say you have You have your internet service provider your ISP But for one of a better word, they're kind of crap and you've got a second ISP available You're like, ah, they weren't so good. So I'm just going to go over to ISP to and that this is exactly what happened to me So you you know you get the whole new internet in and you're like, oh wait, they're kind of crap, too It's surprising how many people encounter this issue. I've seen YouTube videos about this in India the US me here in Israel So this is not actually a far-fetched a scenario So let's say you work from home and your business depends upon you're the quality of your internet So you're going to want that internet to be super reliable Now the secret to doing this is to get multiple internet connectivity and it doesn't really matter What kind of activities you use the idea is that you are multiple and basically just comes down to simple mathematics right if you have internet one that's online 80% of the time but offline 20% of the time and ISP 2 is online 80% 20% off then if you combine those two You're going to reduce a minimized likelihood. Now you can take you can take this exponentially further. You could Sign up for three internet connections, and I'm sure that places like emergency You know emergency dispatch centers probably actually do sign up for like three four ISPs even in mobile broadcasting when you see TV crews and shooting they use something called connection bonding the commonly bonds up for a five connection So it's at this this kind of stuff isn't actually so theoretical something people really do Let's take let's keep it simple for the purpose for example, and let's just say we're going to be using two ISPs now. I'm just going to say ISP one. Okay, so let's say it's going to be VDSL or coax connectivity So if you're in the US or fiber for that matter, so people will say well once I've got fiber I'm set right and that's not necessarily the case. I'm waiting on fiber as I mentioned I thoroughly intend still using the setup even post fiber because speed and reliability are not the same, right? You're going to have a really fast internet connection, but if it goes down a bit, it's not so good So your first stage here is To sign up for two internet connections. Now, let me let me just roll back a little bit What we're doing here is splitting out a network into its components, right? So what when people think of a? a Router what people commonly call a router, right? You say or The box the thing sitting in your cabinet that connects the internet. It's actually a few components in one. It's a modem It's a router and it's a wireless Access point. Okay, so what you may think of is just a It's more complicated than it looks right And what we're doing in this network design is basically splitting that out into different components So let's get back to this So the first thing we're doing is we're going to be using our ISP and ISP to now what I did personally is I Set up cellular internet. I bought a 4g data sim. I bought a mode I bought a 4g router, but again, it doesn't matter now. This isn't about the details here This is about the concept So I'm gonna say it can be anything it could be an ISP so you could use two fiber connections or it could be cellular or It could be satellite for that matter now if you asked me, which would I choose? What would my dream internet set up be it might be something like? ISP one Fiber and I'm gonna tell you why in a second ISP two would be let's say VDSL and then ISP ISP Three would be satellite now the reason I do it like this is because if you're thinking about what's going to screw up your internet Right, it's it's frequently stuff like a digger outside your front door dug through the cabling right so If that goes down, I'd want to diversify the infrastructure as far as possible So you could actually do VDS or you could do fiber plus cellular plus satellite Now if you start looking into the detail of all this stuff, it's pretty fascinating How does cellular internet work like when you connect on your cell phone? So it comes from towers as people know, but then the towers do actually have to think about it They loop back into the network at some point And the word is evading me for that backhaul backhaul So they backhaul to them to the fiber network at some point, but further up the line further upstream So that would be that and satellite is you know coming from outer space literally so that's probably the most resilient So that would be my dream team, but let's just keep it simple. Yeah, and as I said, we're gonna be going for fiber and cellular Now what you want to do here in terms of hardware, so you sign up for your two plans Then you're gonna need two modems, right? Remember we're separating out the components. So for fiber internet, you're going to want a fiber modem For cellular internet, you're going to want a say 4g or 5g modem modem not router Okay, because we're gonna be adding the router later So you get sign up for your two isps you sign up for two different modems And now we're gonna actually add the right router to the network and the writer is going to be a wired writer Okay Wired router now again, I'm not gonna go into product. I'm just gonna tell you how to find these things They are available from Business Internet, I'm just trying to make this box a bit bigger. Maybe I need a rectangle. I need a rectangle. Okay The writer can be It's not your I've your it's not the the router that you typically buy as a consumer because that's intended That's as I said actually three pieces in one. So you're gonna find these called wired writers Internet writers SMB writers VPN writers. Okay, and basically There we go And it just make this a little bit bigger and these are writers that just have ethernet ports But the key thing or I should have added one more the key thing multi-wan writers The key thing is that they have multiple the capability two capabilities that they're gonna have multiple one ports And that they're going to Be able to do something called load balancing. Okay, so these are the names you're gonna encounter this I would search in Like enterprise computer stores for one of these you don't have to look that far if you're in the US You can totally find loads of these on new egg or etc And the capabilities are I'm just gonna clear that away You want something that has multiple one ports and that can do something called Well, it's actually failover technically. It's actually failover Right, and I'll explain why in a second. Well, it's pretty self-explanatory already, but so I'm just gonna say I use personally the TP link ER 605 it's a very very basic load balancing writer. It's only about a hundred bucks pretty cheap as well I actually don't recommend it so much because it's been a little bit buggy at times Other companies you might consider buying from our TP link ubiquity Mickey truck Cisco etc. They all do Products it would fall into this category. Okay, so load balancing writer here in the middle. I'm just gonna say so You've got your two modems and then you're gonna connect these both into the load balancing writer. Okay, and This is gonna be this is going to be going into one one one one So that's connected to the first one port and this is gonna be into the second one port Now I actually advise you will find products by Companies such as Dre-tech that actually try to do all this in one piece of hardware They've got multiple one intakes to the router. They've got a Wi-Fi access point blah, blah, blah I've actually come to believe this is better The reason I say that is because if you buy one thing, let's say in as in my situation You you're waiting for fiber, right? So you're gonna buy yourself a load balancing writer based on your current knee or an all-in-one writer Based on your current needs and then when fiber comes along You're gonna have one ports that don't have the throughput for fiber or don't have the modem for fiber So I would advise splitting out components. It allows you to update your home network in a more modular fashion so and now Here's just the way I've configured my home network so That's kind of the hardware Another load balancing writer you configure internet failover load balancing writer Set up for failover and failover means you just tell the router Okay, I want my primary connectivity to be the fiber link and then if that goes down Please switch me over to cellular and when I come fiber comes back up, please put me back over to fiber Okay, so this is all on the software level and therefore how you do it will depend on your your load balancer Now if you are my network, I personally use an Ethernet switch because Typically on one of these things that you're gonna have like let's say a four port Router and two of those are taken up by your once so to give yourself more Locallary networks capability. I would recommend branching off to a switch and then that's it and then I have everything wired So I have like my NAS and The switch coming off the switch Probably won't surprise most people to know that I'm a desktop rather than a laptop fan So I have actually this computer. I'm using now my desktop was coming off the switch But this is inheriting my desktop my NAS is all inheriting whoops I've got one extra box here. It's all inheriting the balanced internet that has two wands coming into it And then finally you may as well right if you're going to the trouble of setting up this crazy internet setup a Really good AP right you don't need to rely upon the because we're going modular To get your Wi-Fi You can get a really good enterprise grade AP to blast crazy good Wi-Fi internet So, you know something like something like a ubiquity would be good But the beauty again in this network design is everything all the kind of final stage hardware I'm going to color these Yellow the final stage hardware the ethernet switch the stuff that's actually supplying the connectivity all inherits The two connections and that's basically it and then of course just to make this complete because I'm a stickler for for this kind of thing Wi-Fi connected devices at the tail end So they're going to be connected through the Wi-Fi, which is going to be coming from the AP Which is going to be balanced in the load balancer Etc. I Unfortunately have Shaded this and I can't unshade it. How can I unshade it? There we go. De-shaded Sweet, okay. So that's it guys This is a high availability home internet architecture. You've got your fight You've got your fiber cellular or the two coming into a load balancing rider branching off to an internet switch and a really good AP And then you've got your device your end devices connected all the way through Now this is not going to combine your bandwidth, okay? So how could you combine your bandwidth? So what you need to do is something called Connection bonding for that so instead of the load balancing rider you could use something like Speedify on Speedify on it a bunch of server, right? The thing about connection bonding actually bonding up connections is that you need stuff on the one side So it's actually a bit more complicated One VPS, let's say right and the one VPS is going to be bonding Your connections your ones This diagram is getting a little bit crazy little bit crazy Little bit crazy getting crazier Right, you're going to be bonding up your two connections and returning them back and then bringing it through the network So that's what you need you need
