 There's nothing more annoying for me and my staff than troubleshooting Wi-Fi issues. So when Juniper Networks told us they wanted to sponsor a video featuring the solution to our problems, how could we possibly re- How do I go wrong with that? So they sent us over some of their AP43 Wi-Fi 6 access points and an EX4400 switch claiming they've done it. They figured it out the future of networking and the hardware. That's impressive. But the real star of the show is Marvis, the virtual network assistant driven by Mist AI. Marvis combines machine learning and AI with a conversational interface that understands natural language queries. This should save technicians hours of time that would otherwise be spent checking dashboards and using other troubleshooting tools. Certainly seems like a good idea, but what I and probably all of you also want to know is how smart is Marvis? Smarter than me? Probably. But we can't end the video here, so we're going to have to try it anyway. So we started by casually installing two of their AP43 wireless access points and these things are basically the banginest. I'm looking at the data sheet here. It's like limited lifetime warranty, got a humidity and pressure and temperature sensor built into it. It's Wi-Fi 6, but not just that. It's 4x4 with four spatial streams, dynamic packet capture, automatic RF optimization, high accuracy indoor location. So it has Bluetooth on it so you can actually tell exactly where everything connected to it is. It's crazy. So once we were done installing a couple of these, we set up our wireless network and added a floor plan, which was surprisingly intuitive and easy to use given the ones that I have tried before. And now we're just going to go ahead and pull up the management dashboard, which you can see scales beautifully across my dual monitors. Maybe we'll just make it a little bit smaller. There we go. That's more like it. There we go. So this one has nobody connected to it because James isn't even here today. And then this one right here has three. Look at that. Wow, you can actually like see. Whoa, that is exactly where, look, that's exactly where Plouffe is standing. Uh, oh, so coming back to the floor plan, we got a bit of a problem. One of our APs is flashing purple! Click it. Wait, oh, is Jake not done breaking it yet? He's supposed to break it so that we can see how to fix it. It doesn't just like, that's the problem. That's the problem when you're trying to do a video about like, oh troubleshooting. Is that like, usually things work, you know, from Juniper. So you have to kind of come up with contrived ways to break it on your own. There it is. Now it's broken. Thanks, Jake. It's broken now. Now I'm not going to give too many details about how we're hand wavy fixing this, but I will say that this gave us a really solid clue as to where to look, and what we needed to do was dig into our DNS server. In this case, that's the same box as our router and figure out, well, why the heck that access point isn't actually getting an internet connection? And it turns out that the admin, thanks Jake, fat fingered a three where there should have been a two. So now what will probably happen in a moment here is it's going to come back online. Let's try and use Marvis for this. I can't figure out how to reset it. It should be working now. So let's see if Marvis can help me with it. Troubleshoot device, JamesDesk AP. Oh, that is so cool. Look at that coverage heatmap. I like it. Now that we fixed the problem, I mean, we still can't connect to it because like we can't tell it to reboot itself and get new DHCP information because we're not connected to it. But fortunately, look at this. It's all like, oh no Linus. I have a problem. I am blinking yellow six, seven, seven times. Then we're going to go consult the handy key in the software and find out what the devil that means. Oh, look at that. Okay. It still says no DNS response. Man, that is like so perfectly helpful to find the problem we had. I'm just going to go ahead and give it a quick unplug and replug. It's funny how no matter how much AI we add, that's still the way to fix so many problems. Did you try turning it off and turning it back on again? Let's give it a sec here. Wow, red and orange and a bunch of... It's got RGB. It has RGB on an access point. Juniper, you mad lads. That's one challenge down. But of course, what I want to know is who's wasting network resources watching YouTube videos on their phones when they should be watching YouTube videos on their desktops. I mean, I don't actually care if they watch YouTube videos. That's scripted into the video by the by the writer. But I mean, it's sort of part of our homework sometimes to watch YouTube videos. But they should do it over a wire instead of taking up air bandwidth. So I can say the site name is LMG. Can you tell me something you want to troubleshoot? Okay. Let's go with... Okay, he has a Galaxy A50. So I'll try searching for that. Hey, there we go. Cool. Let's click some client insights. Wow! All right. Yeah, I've got a good solid connection speed here and Wow! You know, I think my bigger concern is not actually your YouTube consumption here, ploof. How on earth have you managed to do 211 megabytes of Reddit in the last... What? What is this? Day? Who pro- it's text, ploof. That's my lunch break. That's your lunch break? Oh, I guess there's video on Reddit. Now it's time to do our next challenge here and we're supposed to click second challenge. So this is a desktop computer that's actually right on the other side of this window. And we go in here and nothing is immediately out of the ordinary, but Well, connected time two seconds. Oh, okay. Hold on client insights. Uh-oh So we've got 66 total client events with 15 of them bad. So this is one of those things where you're sitting at the help desk and someone's like, oh, I can't get on the wi-fi And you go well gee Let me have a look at your device here real quick Karen and Oh, okay. You got an authorization failure over and over and over again. I think you might have forgotten your password So here's your password Write it down, but actually don't write it down because that's even dumber Most of the time it's not this cut and dried though. So you'll have things like a problem device that's constantly Disconnecting or running into issues. So that's where being able to sort by good client events neutral and bad ones is Really really useful and you can grab tons of great information from the packet captures And mist actually has this great dynamic pcap feature. That's a blessing to anyone who's sick of trying to replicate issues So it'll actually actively capture data when an error occurs and then store it in the cloud Meaning that you've already got the logs and you can access them without having to go on site Now let's head over to roaming. Oh There it is roaming. Oh cool Okay, so here's a common issue. You can actually see the roaming data between your access points for that particular Client so okay ploof is usually at the Mac desk And then I don't know maybe he had a meeting with James or something and connected to his AP and then he's back on this one so you can sometimes get into situations where you've got someone who keeps swapping bands to 2.4 gigahertz or they get Terrible RSSI values from certain APs and that's all nicely visualized for you Or if you have a device that keeps swapping back and forth from one AP to another which can cause Kind of like a high latency feeling for them or it can cause issues during video calls Something like this can really help you get to the bottom of something funky that's going on Of course what we really want to know is can all of this save me or more accurately Jake time Well our APs are hooked up to an EX4400 switch which offers flow based telemetry power over ethernet PUE plus plus and fast PUE Microsegmentation and end-to-end campus fabric for a ton of scalability So what this means for our next test is that all the extra telemetry should be able to tell us exactly What's going wrong without us having to go take a look for ourselves? And what's supposed to be the problem with this one oh Haha, I got to have figured that out if I had just actually clicked on the thing. Yes, we have 22 bad DNS failures Fantastic now a common mistake when setting up a new mobile device on a network is just entering the DNS credentials incorrectly You might think you entered it correctly while you're just just following instructions famous last words, but unfortunately You were wrong. I Dream of the day when more IT tasks can be handed off to someone less experienced and there's like me and there's zero worry about The network going down because of a rookie mistake so wrong permissions client can't connect that was suddenly down So with Marvis and Juniper networks The idea is that your team can leverage missed AI to proactively notify and correct issues before you get a ticket enabling your technicians To look like heroes so thanks Juniper for hooking us up and giving us an exclusive look at all of Marvis's newest features if you guys are an IT professional looking for an easier solution Let us know in the comments and if you liked this video make sure you check out our horrible server deployment from last year It'll definitely make you cringe your whole face will fall off from cringe. It will go numb and then fall off
