  Maybe it is locked, Apple do not unlock phones, then call O2.

• Satellite L755-1HW: problem of Intermittent Wireless with Sky router LAN

  I recently bought a L755-1HW Satellite from a dealer is seller renovated, but a condition of work entirely, after factory reset.

  I have trouble picking up my sky router (home network). It will pick up my iPhone when used as mobile and is access point find also all other routers of sky in the region, although it will automatically connect to mine intermittently and sometimes, can't find any as a wireless network connection. The sky router can be picked up fine by my father's laptop computer and other phones in the House so I think that the problem lies in the laptop and not the router itself.

  I have recently downloaded a driver for a wireless connection with my printer Epson SX420W, who, at startup, says "cannot reconnect all wireless drivers" If the printer is off, but even when the printer is turned on, the sky router is missed.

  I searched on the web and already done the following:
  1) updated the Atheos wireless network driver to the latest version
  2) updated the BIOS OF THE system to the latest version
  (3) scanned the PC using PC Diagnostic tools and the network is coming as a pass.

  Does anyone have an idea what I can do to fix this issue?

  Thank you very much

  > I'm having trouble picking up my sky router (home network).
  Does that mean exactly?
  I mean that if the wireless network adapter is enabled correctly your laptop should detect your WLAN network. Is your WIFI detected and listed as available WLAN network?

• Problems of internet connectivity with Dell Inspiron 7520 (1703 of Dell Wireless 802.11b/g/n 2.4 ghz)

  Hello

  I bought a Dell Inspiron 7520 for a week now, and I had a strange problem with internet connectivity since then. First, wifi takes a lot of time to connect. After, I'm online, every 10 minutes my network access stops working completely. But if I click on the network icon in the toolbar, it starts working again, but it stops in the next 10 minutes, once again, and so on. If I try to fix connectivity problems, he always find and solve some in the network card or wireless, but then point again, after 10 minutes, or so, it happens again.

  My network card is a Wireless Dell 1703 802.11b/g/n 2.4 ghz and I tried to update and to re - download the firmware, but nothing seems to fix.

  What should I do to fix this?

  Hello friends. Recently I came across the same problem identified by many with a Dell Inspiron 15R laptop 7520 with the Dell Wireless 1703 (Atheros chipset). After losing an entire afternoon and looking at forums and their complaints, I think that I found the solution to the problem (at least, here is running).

  The laptop is connected to a router TP-Link TL-WR740N. The router is configured to run with a frequency of 20 or 40 MHz, making the switch automatically in the factory. The mobile card wireless driver is configured to work only with 20 MHz at the factory. But can be configured to work with two frequencies is adapted automatically. To do this, change the configuration (in Windows 7):

  Start > Control Panel > Device Manager > network adapters > Dell Wireless 1703 802.11b/g/n (2,4 GHz) > click the Advanced tab > select 802.11n bandwidth. Change the value of Auto 20 MHz / 40 MHz.

  Press OK and wait for to reconnect you.

  I hope this helps.

  I can't connect my tablet which has android v4.2 Jellybean. It shows driver not found. what I can do.

  Original title: attach problem

  Hi Andre,

  Thanks for posting your query in Microsoft Community.

  I imagine the inconvenience that you are experiencing when you plug your tablet with Windows 7 system. I will definitely help you in the right direction to solve the problem. However, I would be grateful if you could answer a few questions to refine the question in order to provide you with better assistance.

  1. You did it any significant hardware or change software on the computer before this problem?
  2. What is the exact error message you get, when you say, "Driver not found"?
  3. Connecting the Tablet via a Wi - Fi hotspot connection when you mention, "tethering problem? If this is not the case, how you try to connect the Tablet?
  4. What is the brand and model number. the Tablet?

  The question seems to be resulting in an incompatible or damaged driver that obstructs the connection. First, I suggest you to check if you are able to connect the Tablet via a USB cable.

  In addition, I would suggest trying the following methods and check if the number is reproduced.

  Method 1:

  Run the network troubleshooter to verify connection of the Tablet problems.

  Using the troubleshooter from network in Windows 7

  Also, I suggest you run the hardware and devices Troubleshooter to check for problems with the related drivers that can help connect with the tablet.

  Open the hardware and devices Troubleshooter

  If the problem persists, try the following method.

  Method 2:

  Manually install the Windows 7 compatible driver from the manufacturer's Web site.

• Problems of intermittent wifi with E1 - 510 laptop when power not plugged

  I have the Acer E1-510-4413 model with windows 8.1. 64 bit OS

  When the power cord is connected to the laptop, it works like a charm...

  But when I unplug the power cord, I find that the wifi connection will constantly lose connection to ANY wifi modem that it was connected to little matter if the wifi has been opened or WPA encrypted.

  Very frustrating to say the least when I need Traoré to the power cord on a just full battery charge so that I can have internet connectivity.

  I checked the acer web site and there is no wifi drivers updated so I am at a loss why this is happening.  It always happened ever since I boughtthe portable...

  I found the problem myself...

  Basically, drivers wifi which come pre-installed with windows 8 work very well... but I bought the laptop at the time of version 8.1, and I did the update to 8.0 to 8.1 windows according to needs on my first night to have the brand new laptop.  Tonight, I noticed that the version of the drivers I have for my wifi were slightly older than what is displayed on the download page of the Acer driver for my model.

  So, once I have uninstalled the drivers wifi existing, rebooted, then installed the new drivers and rebooted a second time, my wifi connection was solid...

  not sure why the existing drivers do not work correctly with 8.1, but fortunately the updated drivers are on the Acer download page.

• Intermittent connections with the band of the 5 GHz on WRTAC1200.

  It seems that I'm not the only person who has had problems with the connections on the WRTAC1200 wireless, but I was wondering if anyone here on the forums has found a solution for 5 GHz with the WRTAC1200 connection problems?

  The only solution to find my speed and Wi - Fi is to reboot the router. This solution only works for about a day and then my speeds have completely disappeared until I have restart the router again.

  I played a bit with the canals and the width of the channel, but nothing seems to solve daily problems occurring.

  I've owned the router from July 2015, so I'm well past the return window. I hope, there is an update of the firmware to the corner or just got a router of lemon.

  Linksys is aware of any problems with the WRTAC1200 model? Are there updates firmware out soon? Any help or new would be greatly appreciated.

  Here's what I'm using right now:

  Model: WRTAC1200

  Firmware: 1.0.4.167471

  The ISP speed: 100 Mbps

  I give generally 15-20 feet with perhaps a wood everything in the meantime. Also depends what your HW connection is supported. Check with the Lim to see what modes and speeds based on 5 GHz.

  I tend to test speed wired only as wireless has many variables that can give poor results and difficult to troubleshoot.

• Problem of Bluetooth connectivity with Oticon hearing aids and 10 of the IOS.

• Problems of Internet connection with a Satellite Pro A120

  Hi, I do not know if someone can help me, but I thought that it was worth a try, because I'm desperate.

  Basically, I can't here online with my computer.

  I am currently away from home, back to my parent's House. I usually am on AOL dialup, they are on the same but with broadband, and until last night, I managed to use their connection high speed without any problems.

  I've updated my AVG, and did an update windows yesterday.

  Today while I was doing something, my screen AOL flashed upwards (disconnected) but I thought nothing of it, until what I tried to get online this afternoon.

  Now, while I'm connected to broadband including wireless router controls and I said that I have a strong connection, I get up then a message of not being able to get an internet connection when I actually try and connect. I don't know if it's AOL or the computer, but because I can get on AOL by using the computer, my parents, I guess to it that I don't see that I did something to stop this connection.

  When you try to sign in to MSN messenger I'm also coming with a message that says that my DNS is unable to resolve my IP address. I don't know if that makes no sense?

  I tried to rebuild my log in the location using the AOL software, but it makes all the difference.

  If anyone has any suggestions as to what could happen, or better yet how to solve, I would be REALLY grateful.

  Thank you

  Kat

  First of all, you must check if one of you firewall don t lock you internet connection.

  In addition, you need access to network connections and in the LAN and WLan connection, you should check the general tab-> settings/properties of Internet Protocol (TCP/IP).
  All (IP, DNS, Getway, etc.) must be set to automatically obtain the address

  Last but not least, it would be appropriate to delete your AOL profile and configure everything again.

  Good luck

• Windows 7 problem of bluetooth connectivity with bluetooth for Skype-ing headsets?

  I've read similar questions on the form, and unfortunately I could not find an answer to my question. Starting from 01/12/09, I upgraded to windows 7 home edition with minor compatibility issues (negligible). But, before installing windows 7 I was able to use my headset bluetooth with Skype. Now, sype does not recognize this connection between pc and my bluetooth headset. Ironically enough my pc has allowed for the configuration of my listener. my headset is appointed to be my helmet without wireless/bluetooth for use with Skype or any other program from my PC. In addition, my PC is allowing and acknowledging the connectivity between my PC and the bluetooth headset but not Skype. I tried to reconfigure Skype, but have failed to prove any changes to the default settings. your help is greatly appreciated.

  Windows Update has nothing to do with the upgrade of Windows or your problem. Contact the Skype Support or try to repost your question here: http://social.answers.microsoft.com/Forums/en-US/w7install/threads

  Hi tallenbell,

  (a) what web browser do you use?

  (b) what were the changes to the system between the time where everything has worked, and when you noticed the problem?

  Its looks like you have problems with the browser and not with internet connectivity; to refine the question, I suggest you try the following steps:

• Problem using HP Connect with my HP Photosmart C410

  I try to use my printer HP Photosmart C410 HP Connect applications. I can add the device, but none of the applications seem to work with my printer It' was not THAT old. Any suggestions?

  

  HI beachgrl,

  Welcome to the HP Support forums.  I understand you want to learn what printable sheets are available for your printer Photosmart C410 in connected HP.

  Once you are connected to your connected HP account, if you type the link below into the address bar of your browser, it takes you to a page that shows the pads that you already have on your printer. Under the section "printable recommended" there is a search function.  If you type in your printer model it will list available for the Photosmart C410a platelets. The results will be grouped by category.  I've included a screenshot.

  The address that you need to type in the address bar of your browser is https://printables.hpconnected.com
