Wifi Definition and 69 Threads

The personal hotspot in Android has a Connection Management feature that lists the devices that are currently connected to it. I see that some devices are identified by name, like "raspberrypi" and "ESP_AEEB39" (which is a smart plug). But some devices are just identified as "Wireless device"...

Please help me answering What is the complete list of characters of the complete list of information exchanges standards or any group of characters i can use for my wifi username and password?

My ISP is Tigo Une from Medellín, Antioquía, Colombia i reset my modem before everything i will say in this POST message i did, i have a ARRIS TG2482A model name modem and when i entered in its configuration in " Lan Setup " -> " NAT " To " Nat Mode " i changed my configuration to " Bridged "...

Hello, I have a wifi device that has been connecting with no issues to my local wifi: it first detected the local wifi and I then used the password to complete the connection.... However, one day recently, the device disconnected from the wifi. After some reading, it seems that either low wifi...

A couple of years ago, I connected a USB printer to the USB socket on my broadband router. After a lot of trial and error (of which I remember no details) I was able to print from my windows laptop. Here are the port settings that currently work from the laptop: 1) Based on the above...

As we see the WiFi signal strength is very low as observed in Tunnels, Subways & Undergrounds while we travel in a train or walk. We do not get the wireless network. Can there be any technical solutions for increasing the Wireless signal strength in these areas? Can this be considered a...

One of my relatives has an Amazon Echo Dot and a Fire TV Stick. Both are connected to the same WiFi. Recently, their internet provider changed the proxy settings such that the default proxy no longer works. They have provided a set of proxies that can be used instead. We have manually set those...

Before I start, I must say that I haven't yet bought the Wi-Fi router. We have a broadband connection (no modem, just an RJ45 cable directly into the PC). I want to buy this Wi-Fi router and use the broadband connection to power it. Our ISP provides us a static IP, as well as a username and a...

New to Wifi. I bought the following wifi network adapter to make my PC a hotspot for my new smart phone to connect to: I could finally make it work by installing the driver from kelebek333 (from the PPA repo). I created a wifi connection with a method similar to this one. (The IPv4 & IPv6...

Hi! I’m doing a little mod/add-on to my Sonos One wireless speaker (don’t ask what and why, long story 😅). My question is, how do you think this construction may affect WIFI-reception? I’ve marked the places where I think the antennas are, do you think the metal wire may interfere in some way...

My Samsung S8 has a weird problem. The wifi is not working. After bringing it to official Samsung Service Center. They tried fixing the firmware and software. But it didn't fix it. They said they couldn't fix the wifi module because it is inside the motherboard so have to replace the entire...

Hello, I have a laser cutter which can connect to a wireless router via an ethernet cable. My laptop accesses the internet through the wifi provided in the office (I don't have access to a broadband modem). Is it possible to simultaneously be connected to the internet, via wifi, and at the...

Hi PF! Today my computer randomly didn't connect to wifi. So I restarted the machine, then still unable to connect, I asked my wifi to forget the network. Now when I try connecting to it, it asks for a username and password. At the bottom there is a "connect" button I could toggle, but it is...

As discussed in this thread, I could convert my desktop PC to a WiFi hotspot, and it is working fine, with a more-or-less good range and a good speed. Connectify, the software that I am using, is advising me to install a VPN and is advertising their own VPN software (which, by the way, goes by...

I am getting one of those $10 WIFI units from china runs on 120 volt AC and I want it to run off of 12 volt DC car battery I am thinking will need to open up unit and try to figure out what the DC voltage is that is coming from the AC supply unit and then insert a fixed regulator of 12 or 5...

I'm thinking in a typical house or office, areas of constructive interference may exist which aggregate the fields of maybe 10 WiFi devices. Wouldn't this mean the safe power levels stipulated for any single device would be routinely be exceeded? And if so, do we care?

I was reading online that Connectify can be used to convert any desktop or laptop PC into a hotspot. Our PC is fitted with Windows 7 Pro, 32-bit. It doesn't have an inbuilt WiFi adapter, and connects to the Internet using Ethernet. I wanted to make a hotspot using this desktop. There are...

Hi all, I am planning a trip where I will travel to the pacific western United States. The states encompassing the trip are Idaho, Oregon, Washington and northern California. I want to upload some data along the way. I have been seeing many maps that outline hot spot coverage with companies...

I'm working on a wifi device testing box and made the first prototype of the Faraday cage. I need holes because of cooling. For this reason, the box has 3mm diameter holes on the top. The box made from steel, and have 2mm wall thickness. The wavelength around 12,5 cm for 2,4 GHz and 6 cm for...

I got something i want to do for fun and help out a...person i know but i never finished high school so that's my degree level. i was wondering if there is a way under $100 to possibly use my internet or posibly 2 peoples internet connections on the other side of the town i live in, split up the...

Hey guys. I am building a system for me and a few hundred people. We are incorporating the ESP8266 module to send data over the internet. Each house, however, has its own wifi. Does anyone have any solutions to this problem? I was thinking of setting up an access point and somehow sending data...

Hey guys, quick question on this module.The manual states " 5V-3.3 converter onboard for operation from USB" Does this mean that i can power the board straight from my computer without error from "overloading" the board.i ask this because a lot of other modules such as these don't work like...

Does anyone know how i can send information to the web through motion sensors?

Hi, Sorry if this is too simple. I was given permission by an employee to access to the Wifi service, using my PC, at a FedEx store,i.e., I will not be using their computers. I thought this would be straightforward: I would be given the key/password and then just log on to the network. But then...

Hi While I am working with Norton to fix my other computer, I have to pull out my old laptop to use at the mean time. It fails to connect to my wifi. It was working before two years ago, now it's not working. I open the troubleshoot and it detected that "Windows can't communicate with the...

Would you ever use their free WiFi on your cell phone? Wondering how safe it is and whether any precautions should be taken if I were to use it. Anyone ever been hacked/compromised in some way using free WiFi at a place like that?

hello people . i don't know if this is the right place to ask , but I'm studding for my cisco ccna and now I'm learning more about radio waves and wifi networks and i fall in love with the subject , what i don't understand is what's the difference between a radio and a antenna , because i asked...

i ve got an Arduino Uno R3 and the OV7670 camera module SD Module and a Wifi shield . ive done tweeting with arduino using twitter library http://playground.arduino.cc/Code/TwitterLibrary i was wondering Is there any library to post images in a tweet? or some other hack?

I have way too much time to spare, so I came up with this fun little project. What i want to do is use my phone or laptop to incrementally collect data on WiFi strength at my location at that time, using GPS (longitude and latitude), and once I have enough data, (I'm fine if it takes like...

I use waze and/or googlemaps to navigate. When I plan a route I 1st turn GPS on on my phone. Phone then always asks me to also turn on WIFI, but I always ignore this and leave it off because I thought its pointless if you're not actually connected to wifi. But does WIFI being on (without being...

I'm currently working on a project involving Wifi transmission. The device needs to send a 1-3 digit number to a computer/phone that is 5-15 feet away. Approximately how much energy will this take to send one number? Thank you! Austin

Does anyone know how to locate the wifi transmitter on a modem circuit board, is it the "Radio Transceiver"? Once located, is it possible to remove it or disable it. Wifi is enabled on my modem, and disabling it via software doesn't work.

Hi there, Wifi uses either 2.5 GHZ band or 5 Ghz band and these bands lie in Microwave in EM spectrum. As i read in books, Microwaves are propagated using line of sight (LOS) technique, so sending and receiving antennas should need to be aligned accordingly. But WiFi signals are broadcasted...

In our school we made a submarine. The inner hull is a few cm thick metal, so it should be a good farady cage, but it does not act like one when blocking wifi from inside the hull. Wifi antenna is not touching the hull. The hull acts like a faraday cage when blocking a phone signal from the...

Dear Group, I just set up a Microsoft Virtual Wifi Miniport Adapter using administration command prompt, its function as wifi hot spot, so the other devices could use this hot spot for the internet. ( ) But whenever I shutdown the computer and turn it on, I can not find it, I have to...

How to check wifi's connection download or upload speed? is there some ip address or something else?

I've seen the vice-versa of it by using a hotspot but when use on mobile it asks for mobile data. Why can't it only share the wifi?

berkeman, I read a post of yours stating that "the house next door a wifi cell tower was more dangerous than the one with the antenna on top" Would you please elaborate? Is this because of the umbrella effect? I am considering buying a home which is next door to a house that installed a wifi...

Hi fellas! I am planning to start a ISP in our region, which uses cellular tower for bandwidth signal receiving & transmitting. We have established the leased line back bone to our network and figured out microwave & GSM antenna concepts to receive signals from suppliers and to send signals to...

So I made this Faraday Cage to block wifi in all directions but 1, to block it from my neighbor. Each side has 6 Layers of aluminum foil on it with no gaps, It looks sloppy because when I tried it and it didn't work I quickly added more trying to make it work. If I put my router inside this...

Let me start by saying that the point of this question is to figure out if I can do this with items on hand instead of buying a UPS. I have a cable modem and wireless router which require 12V 750mA and 12V 1000mA respectively. In the event of a power outage, I'd like to be able to manually...

I am curious to know how the RF front end of a Wifi receiver works. From my understanding, most RF receivers have to use networks of various oscillators, mixers, and filters to select a given frequency and remain insensitive to undesired signals at different frequencies, and I suspect that WiFi...

Hello everybody :) This is my first post! I have a mystery about radio communication that I was wondering about for a long time: If I have understood correctly, most computers have a single WiFi antenna in the shape of a rod, which is placed in a particular orientation. My question is this...

Is there a program i can use or do i have to create one? If so,is it even possible?

Hi everybody, I was wondering how much induced EMF would be produced in a 20cm diameter coil with 100 loops produce. Has anyone conducted such an experiment? I am interested in quantitative values of the experiment. Thanks, KB

From what I understand, laptops have a wireless adapter that sends radio signals at a specific frequency to connect to a wifi router. My guess is that the wireless adapter is some sort of radio wave emitter/reciever, and could in theory be used for any other purpose besides connecting to a...

I'm 6 blocks away from campus & probably 4 blocks out of range. I'm a student at the university so I do have the security code. I'm only 1st year EE, so I'm looking for advice. I can follow a schematic, but lack theory of operation that many of you have. Options?

My laptop doesn't like public wifi for some reason but iphone has no problem connecting. Is there anyway to have my iphone become a hotspot with another wifi instead of 3g or 4g?

Hi, just a simple question. We've always been told that microwave ovens are dangerous and to not stand near them when they're on, obviously because they have the ability to heat up water molecules. I just read that the microwave frequencies they emit are 2.45 GHz. Wifi signals consist of 2.4...

Hey all! I am gearing up for next year to do a senior project, I want to knock it out in my spare time for the next 10 months. Ideas are: 1) Laser guided missile- 2 phase motor, one to go up then again to go to 'lazed' target. 2) Wifi barrier- setup focused jammers to create a 'wall'...
