I'm here now because Linus told me to watch it again in December, 2022
Eyy same here
It's the almighty algorithm, I doubt LTT had anything to do with it.. ALL HAIL THE MIGHTY ALGORITHM.
Same
Incredible how much the channel and Linus has changed
Yup... Same here lol
Damn, love getting redirected to baby linus videos
and I missed how CLEAN those videos (editing) are.........
2:00 Wait, you're telling me that 2022 Linus should listen to 8 year old Linus and not use 100% wireless devices so not every device is competing for air time? 😆 Wireless speakers, I mean, come on! 😆
I mean... I really hope you've seen the latest video 😅😅
There is a new wireless speaker video haha, a second one. Some how I ended up on this old video too.
How to optimize your Wifi:
- Wire it up.
cool dude
Holy colour saturation batman.. You guys got that turned up so high Linus has Hepatitis.
I always imagined it as a person about to boil in the vaccuum of space. lol. I agree, shit must be right on the line.
It's a solid product. I had a dbx until someone borrowed it from me, I forgot who and never got it back.
Their price range was a lot more acceptable early on but now they are just too expensive for home use so I won't be buying another one.
I think there's room in the market for a new product like this.
After all, their hardware are fairly standard and their secret sauce are mostly driven by their software which others also are making these days. So all we need are for someone to produce a new USB device.
I've used this before and it's pretty awesome. It's definitely worth the price if you need to determine weak points in your WiFi coverage in a place such as a business.
December 2022 crew represent! lol
Thanks for linking to a Baby Linus video in your latest one, guys.
That microwave comment was actually really neat, i have Sennheiser RS 160 wireless headphones and i usually listen to music around the house, but when i try to cook my minute made rice, they stop transmitting music, and now i know why.
Godamit Linus media group upload midnight every time
It's 11 am here!
no they are uploading just right time at around 12-13
around 8:30PM for me. Great to watch before going to bed :D
6:00PM, shortly after when I get back from school.
Normally about 7am for me, good for waking me up.
TheAwesonymous
same u r aussie XD
I need to optimize over 5,000 access points, in over 200 buildings, on over 450 acres, while dealing with close to 30,000 clients, and fighting configurations with over 9,000 rogue access points. Our solution was with Aruba Networks although we do use the MetaGeek Products for some trouble shooting. Being able to recognize the interference device is the hardest thing to do in the spectrum analysis of Channalyzer. Also a very difficult thing is tracking down devices which have intermittent broadcasting sessions.
Thanks for uploading at 3:06 in the morning
He just finished his build guide. I think this is just here to wade us over until it's been edited and uploaded.
It's after 5 AM here. Luckily we have the option to watch these videos at our convenience.
Chris Alter It's about 11:30 AM in the UK so I'm fine :)
11am here in the UK!
Gershon Dharmanandan Really? 11:33 AM in the south of England :)
One of the better videos I've seen from you. Informative and nicely composed for easy understanding :)
dude imagine a few years in the future where this is combined with google glass or oculus so you can literally see the wifi signals flying too and from your router.
That's an actually pretty cool idea. Sort of like the movie Lucy when she saw digital information streaming through the air.
Wow. So much info thanks for talking about all of this Linus. Really crazy to see what all can mess up your wifi signal!
I work for the cable company. So I set up a lot of home wireless networks. Customers get upset when their " 300 foot range router" is only transmitting like 50 feet properly. So I have to sit down and explain interference to the customer. This will be a neat tool for me so I can decrease as much interference as possible.
newest video linked me back here. device is no longer for sale. any alternatives?
You can just do this with a cheap software defined radio...
My thought, exactly!
Elaborate
Was gonna post this. Happy I'm not the only one. gnuradio is free, a usb adaptar isn't expensive and for home networking a cheap antenna will be more than enough. No need to spent 1000 bucks for this.
itastain check out rtl-sdr.com you can buy a £15 wireless TV dongle and use it as a spectrum analyser
What's a good one that will do 2.4/5.8ghz? That RTL2832U isn't going to cut it in this frequency range.
I really liked this video. I just got into using Wi-Fi about a couple years ago, and this was really informative. I'm a gamer and all my PC's were wired in the past. Going to share this on my FB page.
Holy balls Batman. As most I came here from the 2022 video.... Damn it fking love it!
6:12 After looking at the other bitrates, Linus' shirt says it all.
In germany, the "AVN Fritz.Box" is a very common wireless router which has this feature implemented on even the cheaper models, that come free with your contract.
it's really nice. found it a few years ago and used it in our company... great graphs and optimizing potential
Great video Linus, really enjoyed it.
Super expensive though - and for future reference, it would be nice if you mentioned the price BEFORE rather than after the review - simply because some people can get an idea of what price range you're reviewing it at.
Anyway - great tool it seems, but very niche too.
I both want one of these and am glad I do my games/streaming/other stuff all over a hardwired connection with my PC.
I probably will get one, see what I can optimize and mess with. Tools are cool.
the top meter is called an rta (Real Time Analyzer) and the bottom is called a spectrograph
Depends on the tool. A lot of Wi-Fi-centric spectrum analyzers call the top graph the "Density View" since they predominantly use Color by Density. Bottom graph is called "Waterfall View" or "Swept Spectrograph" depending on the tool. I really like "Real-Time Analyzer" though... That is very descriptive.
General knowledge about wifi and signals improved! Nice video, now I know not to try to stream stuff while in the kitchen and the microwave running. *thumbs up*
All of my neighbors have the cheap basic routers provided to them for a monthly fee. Rather than using the optimal 2.4GHz channels (1,6,11), some of them have foolishly changed to alternate channels, believing that they're avoiding any overlapping interference, when in fact that is precisely what's causing it. As for me, I bought my own high end dual-band router and get to use the 5GHz channels practically all on my own.
This will be awesome for work to be able to roam and map the halls
The HackRF One does all this, has a much wider frequency range (10MHz-6GHz vs 2.4GHz/5GHz), can transmit, and is 1/5 the price.
I have no idea what is he talking about but it's interesting to know that so much go behind just a wifi signal nice.
two videos! yay!
Very interesting to know now simple electronic devices can affect wi-fi signal. your videos are quite informative.
Awesome as always keep up the great work!
This video was quite helpful, thanks Linus.
That is pretty awesome. I don't really have a need for this since I don't work with networks or anything, but I would love to play with that thing. :p
Such a great video, so informative!
Haha it was cool seeing the microwave oven in action!
It was a 2 in 1 TechQuickie and Unboxing :D
Buying an full EM Wave Analyzer gives even more detailed view in very high professional way with higher price
Like Agilent's FieldFox analyzers or Tektronix RSA306
This is sick.
Awesome video Linus, that tool would be so useful where i work, our wifi is constantly being crippled, we're in downtown Montreal so its not a big surprise but i'm sure it would help us knock down a few sources of interference.
I almost recognize the microwave scatters.. same in the basement of a building nearby with their elevator and backup generators kicking in over weekends..
Really nice video as always keep it up !
Good to know .TY
i have a question when ur going down the upstairs how the hell u hold the camera?
Linus and crew, if you are looking for a cheap open source solution take a look at RTSDR software defined radios are great for this application as you can get the same type of graphs.
Good to know.
I recently had to deal with dropping about 5 - 8 packets every 20 minutes. When gaming this would drop my connection nearly every time (madness). I thought the router was bad. Ended up being a NON-WiFi device nearby. I think it was in the neighbors home. I have disabled the 2.4 ghz network, using only the 5 ghz network. I have not had an issue since. The only device that won't connect to 5ghz at this point is my iPhone 4S. No big deal there.
I loved this video. So interesting. Wifi-analyzer for droids is cool and all but this is some next level shit.
Linus using MPC? At least you have taste... Oh and cool wifi analyzer
Batman in the ESSID list at 3:56 :D
Hmmm... Linus is using μTorrent!!! Software and movies piracy ftw!!!
Utorrent has more benefits than just pirating movies
***** Such as?
Χρήστος Φασούλας uploading large files that you would generally have to pay money to companies such as mediafire to upload, you can actually pause downloads etc.
Let's say you wanted to download a file that was 40 GB. You can't pause it if you do it in chrome or firefox or whatever.
***** yeah for example a lot of games (particularly MMO's) will use torrents, because of the extremely large file sizes, heck even the Humble Bundle has offered torrents since day one from what I remember.
Χρήστος Φασούλας Much faster to download things when lots of people have seeded it (I think that's the right term, I've not used it for a while). It also means that you aren't downloading a file from the server of the person that owns the file, but from all the other people who have downloaded it. This allows, for instance, game developers to release a Torrent download of their game installer, but then not have to worry about using all their bandwidth to supply it to consumers.
Linus, do a review on the Corsair Spec 03. Its a budget case, and it has many features with amazing airflow. Also, the windowed side panel has NO side flex to it on mine. I just got my gaming PC put together and the Corsair Spec 03 makes it look bada$$!
As a CWNP certified viking, I approve this video. :-)
I can't get WiFi on the 2nd floor. The concrete ends in the air, so they used a ton of steal to support it. The good thing is, that downstairs, there is almost no signal coming from outside, because the windows are made out of 3 sheets of glass. The bad is, that the phone signal is really bad.
Wired Master Race!!
So now I can yell "don't use the microwave I'm playing spore on my laptop" to my parents.
This Tool Looks Really Fun
COOL !!!!! ... .. one of these would be So much fun for Science.. Radio waves!
Sweeeett ,thx LinusLinus
i can do the same thing with a 20$ solution.. not worth it guys..
My dad worx with things like this (different purpose though) that are more like €80000... This device would work really well for people who know what they are doing. For consumer's it's just plain overkill.
Exactly. I couldn't have said it better.
He state that it was for PROs sorry but a PRO doesn't hesitate about real solutions.
Can someone please help me? I have a MacBook Pro 13" early 2011, a Logitech G700 Wireless Gaming Mouse and a logitech G930 Wireless Gaming headset and sometimes i get 0.5mbps down instead of the 20 I have on other devices and through LAN. Is it possible that either of these 2 devices is messing up my WiFi connection?
by the way, the waves of microwaves are a factor 10 shorter than anything what would cause any interference with anything in the human body^^
I just realised how unfrequently Linus misspeaks himself. And when he does, it feels "special". :p
Could also use a SDR, may be cheaper, may not be as easy to setup
I've always wanted to use this on my house because I know in certain places of my house my g930 headset will just drop connection. I can walk 30 feet from the receiver and still have a solid connection but if I walk into one of the bedroom, 5 feet from my room, I always lose connection immediately despite there be no wifi devices around. It baffles me why this happens.
Ubiquity has very similar thing built in their products its called Airview and its in their whole Nanostation M line could you review that pls ?
for diagnosis its ok, but how to control bandwidth(internet speed) for other in wifi network. eg what would u do when Slick using all of ur bandwidth and u can't even open an email!!!!!
Is there a cheaper and or open source alternative?
For my cheap friends; the same thing plus LOTS more can be done for a $10 SDR, GNU radio and a little bit of knowledge.
this whole video was worth watching till the end just to see the microwave part.
I try to wire up everything I can. I have a few non-wifi 802.11 devices. Sometimes when I play XBox with my Astro A50's, I can hear my phone getting updates when it's near me. I usually have no problems though
I'm pretty sure you can do most of this with a regular wifi card and some special software...
Ive got a question. I'm planning on upgrading to gigabit internet, but I dont know if I should buy a new higher end router, and modem. Or just one or the other? Is a new modem necessary?
What is your modem and router?
Yes if your router only has 100mbit switch inside
very cool stuff
fancy stuff, i just have a 5dB wifi receiver antenna just solves the problem for me and it's just 20 bucks. also u don't have to break your head over it.
Great videos!!!!
what hsppens if i have a 3.5Gigaherts WiMAX modem next to my routher
Can you talk about the upcoming 802.11ad WiGig devices? Or how 802.11ac seems to be abandoning the 2.4Ghz band?
Wow his old intro is awesome
No wonder I can never watch these videos in my kitchen while waiting for food
What is a alternative to inssider for Mac
Wow. Blast from the past
That's actually a bit crazy to see how much noise comes off a microwave!
"Welcome to...how to optimize your wifi!
>.>
That awkward moment when your neighbor's Wi-Fi has stronger signal than your Wi-Fi. I'm right next to my router, too.
The only thing I took away from this video is that home appliances can fuck with your wi-fi. I'm not sure I knew that was possible?
Interesting!!
existe una opcion gratis(for free) en el android market y si la combinas con un telefono con wifi AC (ej motorola motoX 2013) tienes la misma herramienta( o casi la misma) pero mas portatil, la aplicacion es WiFianalyzer, ahora si la complementas con wifi Inspector, tienes una poderosa estacion de auditoria de redes en tu cell phone...
great tool for network architects
To be honest this seems really lack luster compared to the huge price tag. 1 grand for a wireless dongle and some software? Backtrack has similar tools and its free.
fascinating
the wi-spy is way overpriced, especially since it will not help with devices out of your control, and for ones in your control, they often list their frequency, or will have an FCCID which will list which frequency it uses. My main complaint is just that it is overpriced, the hardware inside of it, is pretty much worth less than $10It is basically using 2 dirt cheap radios (1 for 2.4GHz, and another for 5GHz) (often sold by Ti for less than $2 each)
They have far lower data rates than a true wifi radio, and are designed for low bandwidth communication (less than 100kbit/s), they then have it send raw samples which their software then interprets as the graph that you see. (similar to the RTLSDR. which cost $8 and does 22MHz, to 2.2GHz, and offers a higher data rate, though the dynamic range is only 70 dB VS the 94dB of the wi-spy dbx
The 2.4GHz only model is simply a USB controller + a TI CC2500 (about $3 worth of hardware not including the PCB) they then sell it for $750 (their software has fewer features than even SDR sharp (a free program)
furthermore, TI sells the 2.4GHz wi-spy equivalent for $50+, it is the EZ430-RF2500, and some users already made some code to make it function as a spectrum analyzer. e.g., jmkikori.homepage.bluewin.ch/devel/ez430-rf2500.html
I know, right? But I guess they expect some pros to pay such a large premium for it.
Razor2048 you can build one of these things for 20$ with a raspberry Pi and a radio antenna
BOM and cost to develop are two totally different things.
listen to him at 2 times the speed and see linus turn into a chipmunk.
Wanted to also add that the wifi helper tool is the biggest waste of money that have. Iy is not automated, and all it does is walk you through changing the wifi channel of the router, and then running a web based speed test on each channel to determine the best one. the problem is that for most people, their wifi will be faster than their internet connection, thus leading to inaccurate results. It does not perform a LAN based speed test between 2 computers on the network in order to determine the best performing channel. For example, suppose a user has a 20mbit down and 5mbit upload internet connection and eavh of the 11 wifi channels can do well above 20mbit/s in both direction, then wifi helper will be unable to choose the best channel as all of them are being bottle necked by the WAN connection.
If a user knows how to change the wifi channel on their router, they can do everything that wifi helper does using the router's webUI and speedtest.net
To accurately determine the best wifi channel, you must do a LAN based speedtest on all channels where the only possible bottleneck is the wifi connection, and then over the course of probably an hour for each channel, compare the average speeds and look at the throughput graphs in order to see which channel offers the best overall performance.
Wifi helper does not do this and thus, it is 100% useless and offers nothing of value over the free inssider 2.0
why isnt this released for public?
Can you do a video about Wi-Fi extenders.
Does this increase the mbps on laptops?
And this might sound stupid but can it be used for desktop pc's as a wireless network card?
If it can how much mbps would you have. It might be really stupid because a network card is cheaper.
Van someone tell me.
No router or tool can actually GIVE YOU ..MORE mbps than what your ISP is already proving through the lines that you modem or gateway already provide. All this could possibly do is help you get back whatever mbps you are losing due to interference. That is the entire point of this video. All good vibes intended. cheers.
I live next to an airfield. talking about heavy broadcast interruptions...
