looking for WiFi

Hello

How will I know if a wifi connection is available?
my application only works with internet and I want to throw a message early on, because otherwise it would look only broken.

I was very surprised that I couldn't find anything on this forum, because the problem seems pretty basic

Thank you

I did it with a url request, and it seems to work

Here is the code:

public class WiFiChecker extends EventDispatcher
    {
        public static var _WIFIAVAILABLEEVENT:String = "WIFIAVAILABLE";
        private var _wifiAvailable:Boolean = false;
        private var _timer:Timer = new Timer(1000, 1);

        public function WiFiChecker()
        {
            var request:URLRequest  = new URLRequest("http://www.google.com");
            var loader:URLLoader = new URLLoader(request);
            loader.addEventListener(Event.COMPLETE, doneLoading);
            loader.load(request);
            _timer.addEventListener(TimerEvent.TIMER_COMPLETE, timerRanOut);
        }

        private function timerRanOut(e:Event):void{
            trace("WiFi Ping-TimeOut");
            this.dispatchEvent(new Event(_WIFIAVAILABLEEVENT));
        }

        public function wifiIsAvailable():Boolean{
            return _wifiAvailable;
        }

        private function doneLoading(e:Event):void{
            _wifiAvailable = true;
            this.dispatchEvent(new Event(_WIFIAVAILABLEEVENT));
        }
    }

  • Looking for wifi on the device icons.

    Hello, I am trying to access the icons used for the wifi on the device. I am referring to those who get green lines depending on the power of the PA (with or without a sign of blocking). Any idea where we can get?

  • Looking for WiFi blackBerry smartphones.

    Hello. I searched the Board of Directors and have not found an answer to my question, so please forgive me if this has been asked before.

    I have a 8330, Verizon is my carrier and I have a data plan unlimited. The wireless in my home coverage is practically nonexistent; e-mails come but all web browsing is very slow. I have a WiFi at home and would like to tap into it, but have not been able to understand how to set up on the BB. Another thread talked about going into options, advanced and changing the selection in the browser to "hotspot browser" but I did not have this choice available. On my phone, it reads "internet browser" and there is no other choice to select.

    A wi - fi connection is available on my 8330? If so, how do I configure it?

    TIA,

    Chris

    Sorry, the 8330 doesn't have WiFi capabilities.

    It's something that would have discovered a tiny bit of research on the front...

    The 8530 in fact, if you can get it... 9650 is also.

  • Laptop permanently looking for WiFi printer

    I have an Officejet 6600 and it is connected wireless to many laptops and main computer. Since I installed the software, I noticed that the 'thought' slider comes EVERY minute. Sometimes, work in the background slows down some applications.

    When I uninstalled my laptop HP printing software sometimes not at all. A few days later, I reinstalled the software and the cursor to work again. So, I know it has something to do with the printer. I am assuming that she is trying to establish a connection.

    It is rather an annoyance than a problem, I guess. But it really gets me upset. Is it possible to stop the connection and use it only when necessary?

    Thank you.

  • Looking for products with specific needs: USB dongle to create WiFi + send traffic through SOCKS proxy

    Hello

    I need a product for a specific use, and it is not easy to obtain the necessary information with the data I found on the web. So I was wondering if anyone knows a Linksys product that fits the need.

    I am looking for a USB dongle to connect to a Windows PC. This USB dongle should * create * a WiFi network and an iPhone would connect to the WiFi LAN. The PC would then play the role of a gateway, that she would share his Internet Ethernet RJ45 connection with the devices connected to created WiFi. In addition, all the WiFi LAN traffic should be sent to a given SOCKS (v5) Proxy (which is actually on localhost).

    You know a product + utility that meets these requirements?

    Thank you in advance!
    Kind regards

    This is not actually a function of the adapter wireless and more attached to the PC operating system.

    If you are running a Windows PC is easy. Given that existed in Windows XP Internet connection sharing. It simply comes down to enable Internet sharing on the LAN adapter and assigning the host adapter wireless network connection. Then, you will need to add a wireless Ad - Hoc for your devices in the customer network to connect too. I guess that the wireless adapter must support wireless Ad - Hoc networks, but I think they all do.

    Linux\Mac have similar support sharing Internet.

    There is also software available that you can install to create a hotspot Wi - Fi with your PC.

  • AXE looking for networks

    Hello, I searched around, but did not find a lot of recent topics and none of the answers accurate:

    My internet speed seemed slower lately and when I click the wifi icon in the menu bar, the status change constantly "Wifi On" to "Looking for Networks.  It just keeps going back.  Is there a reason it does this?  It slows down things?  I recently left my Mac over my AX, but the signal is still listed as three bars, and it's always on my correct network.  I have never select the network or something like that.  I never noticed this problem before, but I don't know if doing things contributed to it or just a coincidence.

    Thank you!

    When I click the wifi icon in the menu bar, the status change constantly "Wifi On" to "Looking for Networks.

    The AXE is not ' Looking for Networks "... your Mac is" Looking for Networks.

    This message is normal and expected and should appear and be updated on every 3 seconds or more. It's happened since that you lit on your Mac first.

    The Internet might be slower... but 'search network' would not have something to do with it.

    What Internet connection speed is your package from your provider?

    How fast can you measure if your connect your Mac directly to the modem using an Ethernet cable connection?

    How fast do your measure if you are looking for your Mac about 6-7 feet (2 meters) from the airport and connect wireless?

  • CommView for Wifi pilot

    Try using the 4.2.2.104 network card driver (AR5006X) also called net5211-Commview for Wifi - but the Device manager says that there is something wrong and gives me code 10.  I have the Atheros 5007 802 WIRELESS network adapter. 11 b/g.  At first, I thought maybe that the pilot was not compatible with my card, but I looked on the site of tamos, and my card is indeed supported by commview for wifi.  So basically, every time I install the 4.2.2.104 driver, my WIFI is turned off and I can't connect to the internet.  Tamos site said that I could use commview for wifi in dual mode, so I don't know what is happening.  I have vista, is this why? Help?

    Hello TA1LGUNN3R, welcome.

    I have confirmed that your adapter is supported:
    "Atheros Wireless Network adapt (AR5001 through AR5007).

    My recommendation would be to try this driver I put together located here:
    http://sites.Google.com/site/pwdionline/home/Atheros5007x7.7.0.329whql.zip?attredirects=0

    Should not be a Vista issue, as this card has been reported to run without problem.
    What is the service pack level are you running out of curiosity?

    Thank you!

    So far, this was the only time where I had it coming, but I have not tried from new record yet.  Actively running programs are FireFox, Pcsx2 and Fraps.  However, I ran these before without this issue arise.  I'm inclined to think that this is a time to screw that maybe something has been registered correctly or incorrectly read memory.

    Hello

    References to Vista also apply to Windows 7.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - device - Graphics Manager - note the brand and complete model
    your video card - double - tab of the driver - write version information. Now, click on update
    Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
    Uninstall - REBOOT it will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
    with their own software and drivers and all other main drivers that you have.

    Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
    Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
    BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
    each installation.

    Always check in the Device Manager - drivers tab to be sure the version you actually install
    presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
    in particular that) so to install a driver - reboot - check that it is installed and repeat as
    necessary.

    Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
    manually by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
    http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

    Installation and update of drivers to 7 (update drivers manually using the methods above is preferred
    to make sure that the latest drivers from the manufacturer of system and device manufacturers are located)

  • Driver for wifi or lan card

    Hi forum,

    trust, you do well. I'm looking for the driver for my lan or wifi network adapter.  I use a HP Pavilion 15-e055sia (full specs).

    The thing is I had initially a windows 8, I rolled back to windows 7, I thought that I would have downloaded the necessary drivers using the pcdiag of the tech center , but I forgot I'd need at least to have net connection to make it work. So, there you have it. If one of you could tell me the driver for lan or wifi card, I would be very grateful.

    Concerning

    HP-lover1234

    Hello:

    Download and install the driver for the second on the list for the ethernet card.

  • Looking for a small part for HPw2207 monitor

    Hello. I am looking for a part of the small circuit board for my HPw2207 monitor. After searching for solutions to a problem of OSD Lock, I found the Menu button for 10 seconds to stop it. However, the switch itself seemed stuck in position 'on '. So, as I am skilled enough to fix things, I decided open the monitor and see what the problem was. Well, I found it. After discovering how to remove the front and back plastic collar, down at the bottom of the screen, where the Menu buttons, there is a small circuit and housing Assembly of switch button, everything was corroded. I took it to take a closer look and what I found? It is cat WEE!  One of the cat of my wife must have sprayed the corner where are these switches, and as the wet cat is very acidic, it had completely corroded the 3 pins on the circuit board connector and 3 of the 4 micro switches froze.  So now my only remedy for this problem is to order a new set of circuit board. So... that's my question.

    Are these parts still available, and if so, how can I order the.   I have a few numbers on the card itself, which is held in place by Assembly of button with two small screws.

    On the front of the circuit board, there is a number, which may or may not be the complete assembly number or maybe the number of circuit board, but I'm not sure. It's here.

    7900771500000R

    On the back side of the circuit board (green) side there was this number.

    490481500600

    I don't even have all of the assembly. Only the circuit board.  I just bought this monitor and can not afford another.

    I may be able to use the monitor without the turntable in place, if it will work. I will go back without her to check. But if this Board is available, I'd like to get one so I have access to the Menu items.  Given that these monitors are still sold (at Staples) I guess that the parts MUST be available, but my experience in the search for HP... Well, I don't doubt that they are not. But just in case where... it's why I'm writing this thread.  Thanks for any help.

    Oh... btw... the cat is now GONE. Story. Good riddance too. Wet that it would be more of this monitor too. Ruined things half a dozen of the mine and it was the water drop.

    Thank you

    Rick

    Hi Rick,

    You could look on eBay for the part or Google the part number. HP considers monitors consumables is why internal parts are not stored.

    I do not think that an extended warranty will cover TCP (tom cat piss), even if you had a.

  • Looking for a printer

    Hello everyone,

    I'm looking for a printer that suite me for about a week now and still have not decided what to buy. I am inclined to it right now

    I print around 10-50 pages per month and I decided to get an all-in-one printer with a USB 2.0 support.

    I'm not interested in Wifi or network printer as I have a pogo plug in unit.

    I don't mean for print speeds high I print very less.

    When I looked at the HP inkjet printers, means advised pages to print is 400 pages per month, which is much more than what I will use eventually.

    My friends tell me, inkjet printer when it is insufficiently used to frequent replacement of the cartridge and that I should go for Laser alternatives. With my needs as a kid, I don't feel comfortable for a costly option.

    Is there a printer that will suit me?

    I have very little knowledge about printers and would appreciate any help

    Thanks in advance,

    Hello-

    Officejet printers would work very well in a situation like this. They will perform auto maintenance that keeps the head of printing and cartridges in good health. As long as you turn off the printer correctly (with power button / stop) they joined the cartridges in the "Service station".
