  • My new iPod does not connect to my 2006 iMac G5 - how to download all my music iTunes (mainly CDs) on my iPod. ?

    MY new iPod does not connect to my 2006 G5 iMac. How can I download my iTunes (music mainly from my own CD) library on my new iPod. My iMac works well, but running an ancient operating system that does not seem to be updated capable?

    This is not possible.  I don't know what specific iPod model you have, but any new iPod does not work with a Mac running Mac OS X 10.4.11 (and support older version of iTunes).

    There are more older models iPod work (you can buy used) and many of them, in my opinion, have GREAT sound quality.  To playback audio, new does not mean better.

    Follow this procedure to ensure that wireless you laptop works as it should.

    Most laptops have a physical switch for the wireless card. Read the manual of the computer and make sure that the wireless adapter is on.

    Check the Device Manager for the wireless card valid entry.

    http://www.ezlan.NET/Win7/net_dm.jpg

    If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

    Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

    Make sure that if there is Wireless Utility a utility vendor is not running with the native Windows wireless utility.

    Make sure you firewall No. preventing / blocks wireless components to join the network.

    Above everything is OK and it connects to the wireless router. Log in from any computer which is, or can be connected to the router with a wire wireless, disable wireless security, make sure that the wireless streaming is enabled and try to connect with no. wireless security.

    When the work turns on the Wireless security.

    Note * people sometimes make mistakes in writing and retype the password for security.

    Another way is to copy in the menu of the router and then paste it when asked of the wireless card.

  • I just got a new modem (Arris SB6190) and now my Airport Extreme does not connect.  It worked fine with the previous modem (a rented one TWC).  Help!

    I just got a new modem (Arris SB6190) and now my Airport Extreme does not connect.  It worked fine with the previous modem (a rented one TWC).  Help!

    Always recommended to reset the airport back to settings by default and then set up again whenever you have a new modem or change your Internet Service provider.

    Turn off the new modem for at least 30 minutes. More is better.

    Perform a hard reset on the AirPort Extreme, then it turned off.

    Make sure that the Ethernet cable connects the modem to the "O" on the AirPort Extreme WAN port

    After the power of the modem 30 minutes down, turn on the modem and let it run for at least 5 minutes by itself.

    Then, turn on the airport and let it run a few minutes

    Set up AirPort Extreme again

    Important note... There are many reports of problems with the modem Arris SB and airports. Both are great products, but they do seem to work perfectly together for some users.

  • the airport does not connect to the internet new

    I moved and now my airport does not connect to my new internet provider.  Can anyone suggestion solutions?

    Any time you change your provider or hardware networking it is always a good idea to perform a complete recycling of your network equipment power. Please check the following Tip of an airport users for assistance. Post back your results or if you need further assistance.

  • laptop older does not connect to new router

    Hello

    I have a laptop Compaq Presario A940NR which is several years old.  Until last week, it was connected through a router.  The router has stopped working on all devices (printer, 2 other laptops).  Replaced with a Netgear N150 router. -connected to a desktop computer, wireless to the printer and 2 new laptops.  Most old laptop listed above does not connect to the network.  I tried (wired) connection directly to the ISP modem via ethernet.  He does not even recognize this connection.  I may need a driver updated, but unable to connect to the internet on the laptop.

    Help! and thank you,

    Hi, Darlene:

    Here are more recent (MARCH 2011) a version of the driver for your Atheros wireless card. I suggest you use it since you have a new router. There was a lot of connection problems with your Atheros card and new Linksys E series routers, for example.

  • My HP shows it is connected to the new router, but does not connect to the internet. How should I do?

    I have a HP G60 Notebook PC with Windows Vista Home Premium, it is about 4 years old. I recently got a new Cisco Linksys E1500 wireless router, which is connected to my home computer. My laptop shows that it is connected to the home network, but it does not connect to the internet. Other laptops in the House are able to connect to the network and to the internet. Mine seems to be the only one not working do not. Why it is not working? What should I do about it?

    I ran the network diagnostics. It is said "a problem with you network router or modem broadband could prevent an internet connection." I have disconnected these two and tried again. It did not work! I have also connected my laptop directly on the modem and it does not always connect to the internet. I tried to reset the network card. My IP settings are set to automatic.

    My internet connection was not a problem before last week (when I got a new router). What is the problem with my computer? Help, please!

    Hello:

    If you have an Atheros wireless adapter in your PC and you have not updated the driver, I recommend that you install it.

    http://h20000.www2.HP.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=321957&prodSeriesId=3688868&swItem=ob-99392-1&mode=3

    Wireless adapters Atheros with former pilots, dislikes the new Linksys routers.

    If you have an Atheros wireless card, and your wireless driver is more than 2 years, I am very confident that this will solve your connection problem.

  • I just installed a new router and now my desktop running Windows XP computer does not connect to the internet.

    Hello

    I just installed a new router and now my desktop running xp computer does not connect to the internet.

When I try to dhcp I get 169..., when I put manually the IP just get no access to the internet and can not ping to the router address. I tried to run the net work Assistant, emptied my dns, disabled all firewals, still nothing.
    Any suggestions?

    The zero configuration utility works very well. But it is a desktop computer and on cable. All other wired and wireless PC in the office is working well, then it's definitely this PC. He came out of nowhere, I install a network printer on the PC but that's all.

    Your messages are a bit terse, but if I understand correctly

    • You have a router connected to the Internet and multiple computers connected to the router, some Ethernet cable and others by wireless.
    • All but one of these computers can reach successfully from the Internet via the router.
    • A computer that can't browse the Internet is connected to the router via an Ethernet cable.
    • You disconnected the cable between the router and the desktop problem and connected it to a Windows 7 laptop and the laptop connected to the Internet via the router.
    • You haven't seen any error message (except, perhaps, a message on "Limited or no connectivity").
    • You have installed Windows XP Service Pack 3 (or at least Service Pack 2)

    Assuming that all the foregoing is an accurate summary of the situation, I suggest that you do the following:

    Open a command prompt window (start > run > cmd > OK)
    Type the following lines and press ENTER after each line

    Netsh reset winsock catalog
    netsh int ip reset c:\resetlog.txt

    Close the command prompt window and restart the computer.

  • New router, same info. Printer does not connect. Help?

    I have a printer all-in-one Officejet 4620 wireless. I have a new router (the same brand and model brand new), and none of my info has changed. My printer does not connect to the internet more. Always has the info saved just does not connect. I had to re - enter the password in all my other wireless devices, but how do I do on this printer? I'm sure it's my fix. I have searched all over the Control Panel, all the web help HP, used the scan doctor and even called HP and they said that my warranty is out I have to pay for my support. Still an issue like this... Was a bit irritating. Or if I have to reset the printer to the factory and Redo setup wizard is too cool. I tried this one on board printer under network without success. Any help on this would be great! Thank you!!
