Is there any way to make a rotating wifi antenna and it stops when it hits a strong signal?
Question by Krayzi99 | last reply
Hello All, Im puzzled by a simple wifi aerial, i have an old pci wifi card which is slow but works perfectly fine, the only downfall is the range so i un-soldered the original antenna and soldered on some copper wire (approx 2mm thick copper) and on the end of this attached a connector and that attached to a new antenna, but that didnt work, The signal was weaker, i know one option is to go and buy a new better wifi card but i wanted to dabble with creating a stronger wifi aerial, (in my head this would work but in practical it didn't). Why And what did i do wrong?

Whenever I turn my dell vostro 1500 on, sometimes the wifi works and sometimes not. At the startup, the wifi light turns on. Even if it isn't connected to anything. I have checked the wifi capability switch on the side and the 'diagnose and repair' is useless. I am using windows vista. Thanks for any solutions.

Hi everyone, i looked at the instructable of the wokfi antenna and the site of where it all started on that topic ( http://www.usbwifi.orcon.net.nz/ ).i found a free wifi access in my area, i got 1 pc (ethernet card+ usb wifi dongle), one laptop (wifi), a nintendo wii (wifi) and an old pc (233mhz, ethernet card) also a spare ethernet pci card and a pcmcia wifi not in the laptop, laying around .here's what i would like to do to have internet for free:- get the signal from the free wifi access point to the 233 mhz pc- use that pc as a firewall- then send the signal thru the ethernet cable and with another wifi (the pcmcia in the pc with a pcmcia to pci adapter or another usb wifi dongle, witch ever is cheaper) because my laptop can't reach the free wifi access point, it's to far..i'm looking for help on this please, i'll do an instructable with it because i think it could also be usefull to other. that whole idea of free wifi to anyone could be used here. because, let's say in a block, dorm, appartment a far away wifi connection could be shared localy. i've been digging for an intense 2 days now but my knowledge about networks and english (my first language is french) aren't that good so if anybody got an idea where to start looking it would be very appreciated.

I'm looking for a board (for the moment a development board would be the best solution as I am prototyping) with NFC and WiFi integrated. I saw that Arduino should launch one with NFC, Wifi and Bluetooth, the board is called Primo. I can't find anything else and Arduino can't announced a date for the launch. For now I'm working with a NFC reader and the Arduino WiFi Board both mounted on a separate Arduino Uno because the two boards are incompatible. Any idea ? Thanks Alizée

Would it be possible to make a WiFi repeater with the equipment on this Instructable: https://www.instructables.com/id/LINUX-LEECH/ withe the addition of Arduino and a small LCD? It would be really awesome and may even lead onto cheap mesh networking! :D Thanks for any help! :)

There are lots of rc cars out there, with wifi linking capabilities, but I was wondering whether you could be in one house connected to wifi, and controlling a chassis/rc car in another house without using Arduino. (I'm really bad at electronics). The reason being, I want to build a Mobile Virtual Presence Device with a fairly large stable chassis that can be controlled from somewhere else. If you can name a way to do this, I would appreciate it. Thanks! -Finzaz

Is it possible to connect an Arduino Ethernet Shield R3 (official) to a wifi router then connect to a different router though the first router? I want to do this so I can make a robot that when it finds a known network it connects to it then dumps the data from the sd to an online server. Can anyone help me with this? I have an Arduino Uno R3 (official) and an Arduino Mega 2568 (clone).

Hi everyone, I'm not a native english speaker so sorry for my language's level. I'm new on the forum. Watching amazing DIY projects on Instructable make me want to do same things. I have a old 5.1 audio kit : http://www.amazon.com/Logitech-Z-5450-Digital-Speaker-970181-0403/dp/B000AM6QHO One of a rear wireless satelite is broken. I tried to fix it but without result. So my new idea is to use this stuff to make something like Sonos Audio products. 5 independant wifi speakers connected to a wifi network to stream music, and most important to sync sound of a movie streamed on TV. In an other project, i want to create my personnal NAS / Media Center with Plex. In fact i want to create a system, to stream video and sound wirelessly from a Data Server. Is it possible ?

Does anyone know a system or how to construct an RFID / WIFI based locator system? I would think that an old dual antenna wireless G router could be used in combination with an RFID tag. So when the tag is moved to a new location within range of the router the location will be saved or displayed on the computer screen. I thought that having a system like this would be great for keys, animals, phones, babies, pills, etc. Here is one example application: Where are my keys? - open the web browser and retrieve the approximate location where the keys were last moved. They are in between the sofa cushions.

Hi, I have a remote for my fireplace. It uses a RF of 303.87 mhz. I was trying to think of a way to build something that could recieve a message over wifi that would then trigger the 'buttons' on the remote. I found some RF receiver/transmitters but everything is for 315 or 430 mhz. Will those work for 303.87? Or was this remote designed to not be easily cloned?

Recently after replacing the router in the house, my main ubuntu machine wifi has become extremely slow and unreliable. The culprit appears to be the speed at which the connection get set at 15mb/s or 1mb/s. The Belkin N300 USB WiFi card is capable of 150mb/s, but for some reason it only operates at really nice blazing speeds for a few seconds to minutes after connecting, showing speeds up to 10Gbit/sec transient when first connecting, and the average internet speeds of ~5-10mb/s, but then instantly dropping down into the k bit/s range in the system monitor. * A wired connection is not an option * I have tried "sudo iwconfig wlan1 rate 150" and "sudo iwconfig wlan1 bit 150" Seems to do nothing. * I have also tried "sudo iw wlan1 set bitrates legacy-2.4 9" This seems to change the connection bitrate, but has no permanent effects, and absolutely no noticeable effects on the actual transfer speeds. * I have tried installing device drivers using windows drivers on the disc, and using "windows wireless drivers" application in linux, though it seemed to have no effect. (I don't think ubuntu is even using those drivers!) At this point I am at a complete loss as to what the problem is. I know that this wireless chip works fine in windows. Any ideas, I am not an expert at this stuff.

Hello, I'm wondering if it'd be possible to control one of those wifi controlled helicopters such as the Wi Fli (http://www.youtube.com/watch?v=SRLE1EedwN8) with a wifi router, rather than a wifi enabled device such as the iPad.

I'll be in a rental apt. in Barcelona and want to extend my WiFi range. Also total newbie to WiFi. Purchased a Lenovo S10 with built-in WiFi. Read Wambat7's "kitchen strainer" suggestion at:https://www.instructables.com/id/usb-wifi-antenna/Given that my S10 is WiFi enabled can I still try Wombat7's suggestion and buy an external USB wireless Network Adapter to try for extended antenna range? Will my netbook automatically 'deal' with both built-in and exernal WifFi adapters and use the one with best antenna reach?If the above is a no go because my S10 has internal WiFI is there any way to extend antenna reach for the S10's built-in wireless adapter?

I am working on adding a helical antenna to a cheap USB WiFi adapter. My question is where do I connect the antenna to existing circuit. I've attached a closeup picture with three likely points. My three main questions are: 1) Where to connect the external antenna 2) Do I disconnect the rest of the onboard antenna (my gut says yes) or just add in the new 3) What impedance will the external antenna need to match? I assume the components between points C&B; and B&A; are for some kind of impedance matching.

I want to hack a wifi router somehow so that I can reprogram it to act as a radar. Emitting a signal for a microsecond and listening for returns and measuring their intensity. I dont know if the hardware in a router is fast enough for this or if it is possible to find an API or something to reprogram the router.

Can anyone recommend a good instructable to boost the reception range for my computer's wifi device? I know there are tons of them on here already, I just need to know which ones might have the longest range. Another thing is what design would be best. The kind involving a parabolic dish/mesh to direct signals to a usb dongle. One that is more of an omni direction antenna. One that makes use of one of the old sattelite tv dishes sitting in the garage. Requesting advice, comrades.

There are currently 2 different systems in production, LIFX (kickstarter) http://www.gamers-pad.co.uk/2012/10/lifx-led-lighbulb-lighbulb-re-invented/ And Philips Hue - released next year (in the UK) http://www.gamers-pad.co.uk/2012/11/philips-hue-wi-fi-lightbulb/ Both systems promise amazing leaps forward in control and ambience, but both are expensive. I think they are going to be a way forward eventually and will re-invent the lightbulb. But not being technically proficient at electronics, has anyone made an instructable or is anyone in the process of making one? I can generally follow instructions well enough, but for the most part this is beyond me to make and design myself.

Hello, I have an AP in my house which broadcasts our wireless Internet signal throughout our house. Unfortunately there is a spot in my house where the signal is not received. I have a spare dlink dir-300 router which I installed custom firmware on (dd wrt). Can someone please help me use it as a wireless repeater. I want it to boost the signal of my other router. Dd wrt has a repeater function, but my router is an atheros chipset so it is not native on my device. P.s: I don't really want some cheap wifi booster made of tinfoil :p . Thanks in advance, Sam
