No wifi, Internet or bluetooth

I'm running a 3520 Inspiron with windows 7 Home premium. I stopped it and when I re started it I have no wifi or Bluetooth. I tried hard wiring for the modem and still nothing. I went to the Device Manager and there is a yellow flag next to Dell Wireless 1703. 802.11b/g/n (2,4 GHz). When I right click on it I get this message: Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might be installed a file that is incorrect or damaged, or maybe it's a malicious software from an unknown source. (code 52) I have not added or changed anything. What is the problem and what can you do about it? Thank you very much

! If reinstalling the drivers did not work, you can also try to restart to fix options by pressing f8 at startup until... on repair option, choose allow not digitally signed drivers, then continue to boot. If still nothing works, go to Device Manager, uninstall the drivers with the yellow flag. turn off your wifi by pressing fn + f2 key. Then turn it back on by pressing the same keys again. On the upper part of the page in the Device Manager, click the action tab, and select check for material changes...

  • I can not connect the Lifedrive to Internet via bluetooth or Wi - fi

    I've had my lifedrive for about 4 years now. It was a gift, and I've never used it that much; Only, I downloaded some pictures, songs & used the calendar; as I didn't have a computer of my own.

    Now, I have a computer with Windows Vista, & I was hoping I would finally get some use out of my lifedrive. But first, the cd accompanying software was not compatible with Vista (& I can't find any way or find a compatible download), & the most important thing is that I can't connect to Internet on my lifedrive via Wi - fi or even bluetooth. This function, I have never used before, so I'm starting to think that it's something wrong from the factory.

    When I connect to the Internet in a WiFi zone, & then I try to open the browser (blazer), it resets every time, & I can read this message: "memory Mgr.c, line: 3759, Word-non-aligned handle.

    When I try to connect to the Internet using bluetooth through my laptop (cable modem) Internet connection, I get this message as soon as I click on 'connect': ' errorerial: Timeout. " Could be a bad cable or defective Modem (0 x 0305)»

    My computer & lifedrive are paired, & this pairing has worked in the past.

    I did a hard-reset of my lifedrive, as this seemed to be advised in your site, but the problem persists.

    Any ideas, please? Because I'm in the point to get rid of him.

    Thanks in advance!

  • My wifi/internet is very slow since the IPhone Update 9.3.4.

    I have an IPhone 6 and since the update (3 days ago) my wifi/Internet is very slow.

    Minutes of need for pages to load, and the App Store and the ITunes App not to load any. Photos and videos need a time very Long if they work at all.

    The wireless router is not the problem because my laptop works fine with it.

    Thank you for responding!

    Here's a tip for the user on the problems of Wi - Fi. Suggest from the top and bottom.

    Alternatively, you can try to reset the App Store first, since it won't load at all. Please follow these steps:

    Close the App Store completely from the window of the selector app by double clicking the Home button and slide up the App Store preview pane until it disappears from the display. Then sign out of the iTunes Store (in the settings).

    Then restart the unit.

    Then sign into the iTunes Store and try to download again.

    (1) restart you device.

    (2) resetting the network settings: settings > general > reset > reset network settings. Join the network again.

    (3) reboot router/Modem: unplug power for 2 minutes and reconnect. Update the Firmware on the router (support Web site of the manufacturer for a new FW check). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (recommended for 2.4 to 20 MHz bandwidth). Channels 1, 6 or 11 are recommended for 2.4 band.

    (4) change of Google DNS: settings > Wi - Fi > click the network, delete all the numbers under DNS and enter 8.8.8.8 or otherwise 8.8.4.4

    (5) disable the prioritization of device on the router if this feature is available. Also turn off all apps to VPN and retest the Wi - Fi.

    (6) determine if other wireless network devices work well (other iOS devices, Mac, PC).

    (7) try the device on another network, i.e., neighbors, the public coffee house, etc.

    (8) backup and restore the device using iTunes. Try to restore as New first and test it. If ok try to restore the backup (the backup may be corrupted).

    (9) go to the Apple store for the evaluation of the material. The Wi - Fi chip or the antenna could be faulty.

  • [Issue] How data is transferred when you use BlackBerry (NFC) Tag? WiFi Direct? Bluetooth 2.1? Bluetooth 3.0?

    Hello

    I saw a bunch of videos of demonstration of tag BlackBerry of all the cool things you can do with the NFC, but it wondered, what happens if all my other antenas wireless, WiFi and Bluetooth, are out of?

    NFC can be used to transfer data, but it is not good for large quantities. I looked a little further and I found this cool video showing the difference to use Bluetooth 2.1, Bluetooth 3.0 high speed and Wifi Direct to transfer large files, such as videos. BB10 already does support Wifi Direct? Bluetooth 3.0 high speed?

    I hope that BB10 supports ALL the performance and maximum compatibility.

    I don't know where to post this question so here's. Please move was a better place. I think that the community needs a session of general development for wider issues.

    See you soon!

    Hello

    Tag BlackBerry, and the APIs available for developers will automatically perform the best way to transfer the data. NFC supports something called "connect transfer" and are the largest payloads or certain types of data (photos, for example) rather than by peer-to-peer NFC, NFC mode data transfer is just used to negotiate alternative transport. In the case of the BlackBerry smart phones, this alternative will be bluetooth.

    For users of touch devices, there is a brief 'conversation' between the devices on the NFC and this translates into a bluetooth connection set up and data transfer initiated through the bluetooth connection faster. This is all without the usual matching process. After reaching the stage of bluetooth devices need closer will be of course.

    The same principle applies to both 7 BlackBerry and BlackBerry 10. In fact talk us a bit about this in our latest article on BlackBerry 10 NFC API:

  • How to share computer laptop computer wifi laptop bluetooth that can use internet with Bluetooth?

    Hello

    I want to share my laptop wifi with computer laptop bluetooth, how to share?

    I need now

    Please help me...

    Hello

    Thanks for posting your query on the Microsoft Community.

    According to the description, I understand that you want to share mobile Wi - Fi.

    I would like to know some information.

    1. What is the brand and model of your two laptops?

    2. The other laptop only has a Bluetooth but no Wi - Fi?

    I wish to inform you that unfortunately, you can not use Bluetooth to connect to the internet. You must have a wireless PCI card.

    Wi-Fi connections can reach a distance more than the alternative wireless listed above. Many newer computers, especially laptops, now contain integrated Wi - Fi capabilities makes it the first choice in most situations. A Wi - Fi connection can be used with or without a device on the network. With two computers, Wi - Fi networks under a luminaire (also calledad-hoc mode) are particularly simple to implement.

    Bluetooth technology supports wireless reasonably high speed between two computers without the need for a network device. Bluetooth is more commonly used when the network to a computer with a consumption as a handheld device phone cell. Most desktop computers and most do not have the Bluetooth capability. Bluetooth works best if both devices are in the same room in close proximity to each other. Consider the Bluetooth if you have interest in networking with handheld devices and your lack of computers of the Wi - Fi capabilities.

  • Why my new iPad and iPhone massively have wifi slowly when Bluetooth is turned on?

    I tried to watch reboot etc until I found a post saying that the Bluetooth is originally the devices have a much slower connection. I turned Bluetooth and got 65 instead of the download speed of 11 gig. However, my watch Apple pencil and pebble being disabled, is very important to me, so it's not a viable option for me. What can I do? A fix is even planned? ! Running the latest iOS with all the patches etc in place. Tried to close everything and restart both devices and the router etc, but disable Bluetooth is so far the only thing that makes the difference. My old mini iPad and iPhone 6 were very good, but I traded them in

  • Disabling a WiFi / Internet browsing

    I recently bought a unlocked Motorola Flipout. I'm with a UK on Pay As You Go network. The problem I have is that I'm a complete newbie when it comes to technology. Basically, I have a wifi network at home, but when out and about my phone was automatically the "internet" connection when I'm surfing the web etc, watch the news and social media. This means that I use a lot of money to top up my credit. I read the forum and I have now changed my policy of Eve Wifi forever, saved data, disabled basic data and ensure data roaming was off and "sync via wifi only. I would like to just that really all the tips, I want to keep up to date with emails etc when actively, I want to see if I have rather than the phone constantly updated and charge me. I did everything to make sure that the phone is not eat my money when I'm asleep for example!

    Thank you

    You've done everything the most you can. You can also get applications that monitor the use of your data.

    Also, do you have e-mail sync value manual - if you use POP email? If you're out and about and no wifi is present, then the cell data will kick in.

    The other thing is the widgets... some updated when you go in for more details - they are no longer the background.

  • Setting up a local network private through the device that extracts public wifi internet

    I travel a lot in a RV I don't have a continuous Internet connection wherever I go, usually a public wifi some Camping I am for. I have several devices that I use, but I don't want that they are open to the public wifi network. I've had people send photos from their phone to my Xbox so that I use and I want to be more secure and control my devices.

    I have a knowledge of basic networking. I was able to use my laptop to connect to a public wifi and then share the connection through Windows on the LAN ethernet port. I then connect that to my old Netgear DGND3700v2 DSL model with its DHCP function disabled. It worked for several months now, and I am able to connect to the ports of my router modem and lan with my devices. But some games on the xbox does not work because I can't redirect ports or control static and other IP addresses. I think that there should be a much easier way to do it.

    I looked in my router Repeater functions, but I don't think that's the way I need to go. I have no access to the routers of the campsites configure them as bases. I need something that will pull simply bind an existing wifi and then deliver this private to my LAN connection.

    Thanks in advance for any advice.

    It worked perfectly. I bought a Netgear AC1200 and easily plugged into the local public wifi. I then wired to the LAN cable/Fiber gray on the Netgear router port and then reset the router ran smart installation thereon and he set up hands down with a new local network on a separate ip address range. Now all my devices independently connect to my router via wifi or LAN and use internet through the Extender without that person outside to get in and I don't have my laptop of aging on all the time to do so.
