Laptop cannot access the Internet unless it is hooked to the modem

  1. Toshiba laptop. Internet at the bottom right says there is a connection available, but says the settings saved on this computer for the network do not match the requirements of the network. It has to be plugged in to the modem to access Internet. Speakers do not work. Ports do not work either. I had it in for repair and he thought it might be the motherboard, but he couldn't fix the other one and I got help with Broni on here and it works fine now. I am hoping someone on here can help me fix this one. It has no viruses; it's clean. Thanks!

    Ok, the modem=>pc config working says networking is at least sane.

    To get the modem=>router=>pc to work, the pc should not have ANY configuration data stored in the network adapter settings. Can you find and clear the network adapter for yourself?

    Hi...I am very basic when it comes to computers, very. I don't know how to find the network adapter. I need step by step instructions. Can I find it doing search? THX

    You need to be logged in as the Admin.
    Connect the Modem-->Router-->PC and wait 30 seconds

    right-click the internet connection in the system tray which gives you this

    CLICK on the Change Adapter

    Dbl-Click on the Local Area Connection->Properties and scroll to (TCP/IPv4) select it and then click Properties
    there are two choices beginning Obtain ... choose both of them.
    click the Advanced button at the bottom right and see three tabs
    * IP settings shows DHCP enabled & default Gateway must be empty
    * DNS should show no settings but have the choice (*) Append primary and connection specific DNS suffixes
    [x] Register this connection's address in the DNS​
    * WINS has NetBIOS setting (*) Default
    click OK taking you back to the GENERAL TAB​
    click on the tab Alternate Config and choose Automatic
    click OK and that is back to the Local Area
    click CLOSE once
    Almost done - - click DIAGNOSE

    you should have no issues at the end

    Hi...Those were excellent instructions. You made it easy to follow, but it didn't work.
    Do you have a Plan B?

    That effort ENSURED we didn't have a malconfigured adapter.

    Now then, with modem->router->pc

    get a command prompt (start->search and enter CMD and hit enter)
    you get a b/w window into which you type IPCONFIG /ALL >MYTCP.TXT
    output can be then be seen with NOTEPAD %USERPROFILE%\MYTCP.TXT

    With that data displayed, COPY it all and come back to this thread
    and PASTE the data as your reply

    I copied and pasted this in CMD; IPCONFIG /ALL >MYTCP.TXT Nothing happened and I see nothing in notepad. Please advise. Thank you.

    Then try NOTEPAD MYTCP.TXT

    The salient portion of all that is this:
    Code:
    Ethernet adapter Local Area Connection:
    Connection-specific DNS Suffix . : Home
    Description . . . . . . . . . . . : Realtek PCIe FE Family Controller
    Physical Address. . . . . . . . . : 00-26-6C-6B-A6-BA
    DHCP Enabled. . . . . . . . . . . : Yes
    Autoconfiguration Enabled . . . . : Yes
    Link-local IPv6 Address . . . . . : fe80::f9bb:4e33:4400:ea82%10(Preferred)
    IPv4 Address. . . . . . . . . . . : 192.168.1.10(Preferred)
    Subnet Mask . . . . . . . . . . . : 255.255.255.0
    Lease Obtained. . . . . . . . . . : Monday, December 15, 2014 8:59:28 PM
    Lease Expires . . . . . . . . . . : Monday, December 22, 2014 8:59:28 PM
    Default Gateway . . . . . . . . . : 192.168.1.1
    DHCP Server . . . . . . . . . . . : 192.168.1.1
    DHCPv6 IAID . . . . . . . . . . . : 234890860
    DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-16-0C-3D-E5-00-26-6C-6B-A6-BA
    DNS Servers . . . . . . . . . . . : 192.168.1.1
    NetBIOS over Tcpip. . . . . . . . : Enabled
    everything looks normal for TCP. The Default Gateway is also the DHCP and DNS server addresses, which says your router has the real configuration from the ISP Wan site settings - - also normal.

    if you perform TRACERT 8.8.8.8
    the first line will be your local router 192.168.1.1
    and line two will be your ISP's gateway address.
    1. can you at least get to line (2) from tracert?
    2. most importantly, does the last line show [8.8.8.8]
    if so, then tcp routing is doing fine.

    Now test your system to resolve a DNS name into a real IP address:

    in the command prompt window, enter NSLOOKUP 8.8.8.8
    you should see:
    Code:
    nslookup 8.8.8.8
    Server:  dns-cac-lb-01.rr.com
    Address:  209.18.47.61   <== this is my dns, your's will be differend
    
    Name:  google-public-dns-a.google.com  <== but you must get this name
    Address:  8.8.8.8 <== for this address
    
    and nslookup google-public-dns-a.google.com must return
    Code:
    Non-authoritative answer:
    Server:  dns-cac-lb-01.rr.com
    Address:  209.18.47.61
    
    Name:  google-public-dns-a.google.com
    Addresses:  2001:4860:4860::8888
      8.8.8.8

    I did the former instructions and have a new administrator. The computer is acting the same as it has. Will try to do the next instructions. This is all very foreign to me.

    I did the tracert. I got to line 8 but I cannot remember the results because they are there and gone and I don't know what to look for them to copy and paste them to you. I don't think that the last line had a series of 8's in it. If you want I will do it again and try to handwrite the results.

    It says default servers unavailable. Nothing like what you thought it would say.

    "default servers unavailable" is a malconfigured DNS Setting :sigh:

    OK. I don't know what this means, but I do not like the sigh. Is that anything like DNR (do not resuscitate)? Tell me more....

    Almost :giggle;

    It means your TCP configurations is bogus and needs to be rectified.

    login as Admin, get the command prompt and enter these:
    • netsh winsock reset catalog
    • netsh int ip reset reset.log
    • netsh winsock reset

    then reboot

    Oh, so you are very funny.

    I did as you said. The first and third were successful. The second said no user specified settings to be reset.

    I rebooted. Internet still doesn't work. What is next?

    So is my computer not ever going to be working right again?
