- WiFi is the amazing creation that lets us stay connected to the internet without any physical connections. But sometimes it can be so finicky. What makes it do this? Let's take a look.

cant even load this video..
You should make a video on how you do research!
intarwebs
Killian Alawi i call it google
It says technology in a nutshell, yet the logo is a nutshell in technology instead.
You pretty much covered the basics without saying that cheap router could me moded with another firmware like dd-wrt and having its transmit power turned up which has its own issues.
Something to mention for speed is legacy devices, your typically limited to the slowest device on the network.
Mark Williams i covered dd-wrt in the tutorial about making a repeater that i linked to in this video, so i thought it'd be unnecessary to repeat it all again. and that's true about legacy devices. I probably should have mentioned it. but hey, that's what the comments show is for! thanks!
Tinkernut oh sweet you replied :-)
I use to mod routers for a hobby and use to build x86 dd-wrt routers (out of old computers) and put in 2x 2.4GHz wireless cards. One was just a high powered 1x1 card dedicated to B/G devices (some would have cards for all 3 B/G/N) and the other would be a decent 3x3 MIMO for N stuff. I built these for companies with weird needs.
I had to be careful to do site surveys and make sure the cross talk or overlapping channels didn't cause issues.
And since A stuff is kinda rare with the exception of the original Xbox 360 wireless adapter I just put in a decent 3x3 5Ghz one for N.
If I still did this I may do tri band for AC stuff but then again dd-wrt, openwrt, tomato, etc have kinda been dead community wise for the last few years and I kinda lost interest unfortunately.
Have a good one, love the videos :-)
This really helped me config my router to the perfect channel and frequency. Thank you so much
Pretty much spot on , I love that WiFi analyzer android app, it's one of the best I've seen and my choice, I understand the antenna orientation, but the real world issue is antenna polarization, although perfectly vertical is probably going to give optimal reception to every device at the same elevation anyways although on a hill it's a different story, another thing I have found is in *some* metal buildings you get dead zones here and there when you place the router in a corner or near the center of a building I suspect this is due to multi-path. Perhaps a video on antenna theory, multi-path interference, and signal propagation theory are beyond the scope of even a couple short videos that will keep the attention of the average viewer.
I've been using 3 access points to cover the whole spectrum, each with the same SSID/WPA2 Keyword and I can just roam from spot to spot and keep the devices per access point low and the distance to the device lower. Both have increased speeds in my house where streaming multiple streams over wifi is typical. I use Ethernet to bring the network to the access point, so I also gain Ethernet ports at each place as well.
The biggest reason for doing this was to cut down on the signal noise from other AP's in my neighborhood. I have trouble breaking -30dB @ 1m because of the incredible 2.4Ghz noise. That and my house is a rectangle so one access point doesn't get the edges upstairs without repeating anyways. Repeaters add traffic and ultimately slow things down. I'd rather have multiple hard-wired access points.
Checkout Ubiquiti Uni-fi 3 pack for an example of an out of the box solution to what I did.
joelb79 before people ask, one AP on CH1, one AP on CH6, and the other on CH11.
You can set up Wi-Fi roaming using two or more access points if your house have good structural cabling. This will allow your device to automatically pick the AP with the best reception. All you need is configure all your access points using the same SSID, encryption method and key, but different non-overlapping channels.
im using sucky wifi to watch a video about sucky wifi. inception
wundrweapon jajahhaha hahahhaa same
refrigerators and microwaves can interfere with wifi signal too. and someone using/stealing your wifi can reduce the speed also.
Thank you for this! I didn't know about wifi channels and found that my wifi is on the same channel as others nearby. Going to see if changing it improves things!
Also to note, a wifi scanning utility exists on newer Mac OSX versions - it's just a little hidden.
My WiFi manages to penetrate a floor, and 2 walls, with almost 8 devices connected to it. And is somehow manages to give me 2-3 bars of WiFi.
Lol
I always wondered why there are times where my phone is trying to load something, and the little wifi icon at the top of the screen (on an Android) will show that it is either sending/receiving data or doing both, but then suddenly it will stop, and whatever I'm trying to do will come to a halt as well, almost as if my phone forgot what it was trying to do and therefore decided it didn't need to continue transmitting data even though it's still connected to wifi.
If you have a router w/ removable rp-sma antennas, higher dbi gain antennas also help immensly!
Thanks again man, you rock!
Here is my 2 cents on the "crowded neighborhood" problem. Most wifi signals use multiple channels for bandwidth. Basically 802.11g would use multiple channels of 802.11b to get that 54 mbs bandwidth. This means that a wifi signal on channel 1 will get interference from any wifi signals on 2-5. So if you neighbor is on channel 1, you need to go use 6 or 11. At 3:08 you will see what I am talking about. Those signals are big humps and a signal will spread amongst channels.
You could use ethernet over Powerline or Power-line communication (PLC) and re transmit the signal at the weak area of the building. I use that in my garage.
+Tinkernut @1:13 or so..... one thing.... floors arent generally thinner than walls in houses.....interior walls have wires and pipes in them generally. floors mainly have floor joists. when they do run wires through the floor, they do it in a fairly straight line. when they run them in a wall, they end up covering more space as they have to supply power to lights, switches, heaters, outlets, ect....so, this is likely why wifi goes through floors better than walls...because there is more metal to interfere with the signal in a wall than there is in a floor.
i could be wrong about metal being the cause....but i've framed and finished many residential houses and since floor joists are generally 2x8's, 2x10's and 2x12's.....while interior wall studs are 2x4's....i am fairly certain that most interior walls are not thicker than the floor. . just fyi.
i love the vids and have learned a ton from them!
flooring its typically wooden signal passes through wood ok drywall is more akin to stone signal does not like rocks.
Verry nice new logo!
Do wireless mic receiver signals work this way aswell?
You should mention microwaves because they can interfere with your WiFi too. If you've got two different frequencies, you're good. If you got one, hope it doesn't match your microwave or else don't use your microwave.
Hi, I work for wireless Internet support, if you live in a place where there are too many wifi signal (yes that does interfere with the speed) why? Because of the channel setting (wave setting) on all the routers or modem/routers are on the default channel 1 , by logging into ur router you can change the channel to a different one like 6 or 11 and that will increase ur speed because all the other routers are using channel 1 and urs is using 6..
Can you have multiple wifi modems acting like the same wifi so you can have extended wifi without changing your ping but stay on the same wifiish?
nice tut
I've heard mirrors mess signals up. In fact I was able to connect finnacy devices, like my old PSP by waving them in a circle eight when near a mirror. Or, of course, leaving the room with the biggest mirror.
i guess whispering to my router every night doesn't work then...
you know who invented the radio
NIKOLA TESLA
ALL HAIL TESLA
***** that fucker invented everything
***** Tesla coil as WiFi antenna = all problems solved! xD
true that
***** Tesla was amazing in the field of electronics! Too bad we don't use his idea for generating and transmitting electricity wirelessly. We wouldn't have to pay an electric company every month!
even if we had to pay for it it would still be awsome
you forgot to mention electronic interference from mundane electronics. like cordless phones and microwaves ect.
I heard that taping batteries to the Ethernet cables on your router speeds up the internet. Is this true?
Place your WiFi router beside your chimney. As the chimney reaches all floors and is open space it allows a stronger WiFi signal to reach further.
GOOD JOB
#LAN_MASTERRACE
i manualy changed the wifi chanels to a less crowded one i got about 30% incres on range and about 40% increas in speed
anyone use that tc8305c Comcast wireless modem and have a ps3 any tips cause normally games like bo2 and gta v disconnect those two games are really starting to annoy me though the modem is in the room next door. Plus I also have a ADT modem next to it
I just upgraded my router yesterday. From the looks of things, even a weak 5 GHz signal is as good as a good 2.4 GHz signal. I get the same throughput with 5 GHz at -70 Dbm as I do with 2.4 GHz at -40 Dbm
I really like ur new technic.....can u do bluetooth technology next?
First choose the least crowded Signal type (2.4/5 GHz) then choose the least crowded channel (You can find that out through WIFI analyzer) available.
I like the new style.
why dont u get a 10Gw wifi antenna
Hey for your next video how about show them how to use a simple raspberry pi as a wifi modem.
Lol blurred out wifi SSID name in the wifi analyzer screenshot. ^^
can you make a raspberry pi b+ Wi-Fi repeater?
Cool my wifi sucks. It probably took 30 min to upload this comemt. I will define lily try that! P.s. Where do your get ur intro?
And what if im in egypt ?
Do microwave ovens can work as a WiFi repeater? :/
+Tinkernut plz do a video on How to make a transparent screen.....
this should be on the comments show and you must answer it
Great video. 5ghz is the way to go, on my 2.4ghz my Internet speed is ~30mbps on 5ghz it's 65mbps and LAN/powerline is 65mbps. Be careful tho as you need 5ghz WiFi cards in order to connect. (most phones/tablets will have 5ghz / dualband card) for static devices use powerline, this also helps remove strain on your WiFi (as mentioned in video) I find also restarting your router every few months helps, I'd assume clears bufferbloat. Happy networking!
Not seen the video, but you can also fine tune the frequency, by making sure you are not using a congested WiFi channel, using inSSIDer. www.inssider.com.
Just realised that inSSIDer is no longer free :/
I have the problem that on my phone the wifi signal sometimes goes up, goes down or even disappears completely. While on my tablet, which is laying only 20cm from the phone, the wifi keeps constant.
Somebody know a solution for this?
I used to be able to connect to WiFi from Iowa to Kansas and now I can’t even connect to WiFi from the outside of my own house
Why when i connect my phone to the wifi it explodes? (Please include this question to your Comment Show)
Now the router shown here is amazing wrt54G old classic
does changing a wifi channel help in any way?
Raunak Joneja some people swear by it, but I feel it's actual help is minimal.
MyPublicWifi acts as both Computer-Everywhere WiFi connection and repeater.
Install it, set it up, restart your computer and turn the WiFi on.
How about coming up with a inexpensive easy way to do a homemade heatmapper! Yes, I could use the free one from Ekahau, but doing it and knowing how would be better. A raspberry pi or arduino would make a nice mapping device.
In any case, thanks for keeping us educated. ... Jack
My Internet sucks so much that I am right next to my modem and can't watch it!
Nice, but you should use both 3D and 2D, 3D can be confusing at times
Changing wifi channel
hey you deserve 1000000 billion subs
My ping is literally 100,000 whenever I try to play CoD
Totally off topic, but why does TH-cam's notification system suck so hard? I get maybe notification for maybe 5% of the uploads from my subscribed channels. Yes I have notifications checked in my TH-cam settings. Is it just me??!!
Need to tell my neighbors about this
Or when the wi-fi drops out constantly regardless on signal strength due to how flaky BT hubs are. :S
I watch this as it buffers, I need answrs
Tinkernut If you use ethernet for all of you're stuff, do you need to worry about interfearence?
U can change ur wifi channel
I threw DD-WRT on my router and cranked the power. I can get my wifi signal from across the street at my apartment gym.
Or u could use an Ethernet cable
My wifi case have 6 poles and it run 1 GBS per/second but it still sucks
Do all wifi card support 5 G?
maluminse1 No. However, most new ones should support 5ghz. The issue comes in to play usually with devices such as game consloles, or anything else that is made cheaply.
abc03833 "game consloles, or anything else that is made cheaply." PCMR.
Science, what is it all about. Techmology, what is that all about
TIP: don't put your router near the kitchen or in between your devices location where microwave and fridge sits, microwaves severely interferes your wifi signal be it 2.4 or 5GHz..
{ room/device }---{ kitchen }---{ router }
Where I live I'm lucky to get copper...
Music?
; (
:'(
I tried using a WiFi repeater, but my local ip changed every 5 minutes.
I did turn my raspberry in a router
Please don't use a wireless "repeater"... You're just taking crappy wireless and bouncing it to another wireless device, at the same time you just added yet another device to cause interference. If at all possible, get a hard line (ethernet) extender or ask your ISP if they offer an access point. Also, cordless phones, wireless gaming controllers, Bluetooth devices, wireless security cameras, baby monitors, hell even some microwaves can also interfere on that 2.4g band.
Put tinfoil around the receiver device such as pc phone xbox and it will work better
What ever happened to the stickman?
my wifi is too slow to load this video... how ironic
I keep getting disconnected 🤦♂️
I’m legit paying for 500 mbps and barely get 1
I dont know how, but my network manages to load TH-cam pretty effeciently, streaming a video without stopping.
Compare it to how it is barely able to load a NORMAL WEB PAGE, which realy confuses me why it does it.
TH-cam = OK
Facebook = LAGGY
Google Search Links = 10 Min to load, maybe, might not even load at all.
Oh the irony. Video wouldn't even load on wifi lol.
my room is on the top floor and the router is in the basement so i always get suckish wifi lol the vid paused at a wierd moment
I personally place my router where something that needs a lot of net such as a xbox one i rather use LAN than wifi
best tip is to just run a long Ethernet cable to ur computer i went from 12mbps to 64mbps in a flash lol
What you have studied?? #Tinkernut plz tell ..
also,
close all your windows, and ventilation, to make sure the wifi, dosent get out and fly away :-D
I bought a cheap router $40 and I get about 130m or 430 feet approx. And that's trougth concreet walls. Still able to load yahoo ;) So you can get good routers for a low cost :P
Adrian Hoffsten Hard to believe that, considering that commercial 801.11N Routers have a maximum usable range of 300 ft, and concrete halves the range of the signal
even max wifi it does nothing :/
Bruh I’m next to my repeater and I’m not even connected to the WiFi
mY Wi-Fi is so TRASH!
Fuck Yeah
Why is this so much in the news lately
A nice tip is don't go with Verizon for WiFi.
jake00000 it's not Verizon's fault. Wifi sucks in general. Go purchase your own stand alone wireless router that is mid to high tier. You'll notice a difference.

i hate my WI-FI its so slow and i always randomly lose it i wish i have more faster wifi and have more FPS
Me2
Because I live in Poland
I know them people that live in apartments big mad.
