    Can't Connect to Internet via Ethernet Now on Laptop - Used to Work


    Hi,

    Don't know what changed, but now when I try to connect to internet on my tiny GPD WIN laptop running Win 10, I get the yellow triangle on the network icon in taskbar and message 'identifying....No internet access'.

    I've checked network connection and cable on another laptop and connection works OK.

    Checked Device Manager and everything looks OK.

    [UPDATE] Just did the Windows Network Troubleshooter.....
    Both WiFi and Ethernet have message:

    Doesn't have a valid IP configuration Not Fixed
    Any suggestions how to get ethernet working again?

    Thank you!

    Did you check your IP settings?

    Go to Network and sharing center (right click on network ico in taskbar and select ...) and quick check on "Ethernet" (if connected).
    Then click on details - look if network IP is correct.
    If anything is out of order, click on "Properties" and verify that IPv4 (or IPv6) shows Obtain IP address automatically. If that doesn't work, select one manually.

    Thank you for your help and input!

    Checked things as you suggested.

    In 'Details', info shown looks OK as far as I can tell....'DHCP Enabled Yes' and shows IPv4 DNS Servers and IPv4 WINS Servers addresses, 'NetBIOS over Tcpip Enabled Yes', although IPv4 Default Gateway has no address shown.

    In 'Properties', IPv4 shows 'Obtain IP address automatically' as well as for IPv6.

    I didn't mention that I've been trying to connect at my work office and ethernet network there.

    I will take my little laptop home and see if I can connect to my home ethernet network. If it works at home, then I will try selecting IP address manually as you suggest.

    I thought you were connecting to NAS on your local network. If you are connecting from WAN (outside network), check the manuals for system. Every system have a bit different approach.
    Please disregard this..

    I assume it is a local network of some kind. I have two separate LAN ports in my office. Use one for my work laptop and other for my own laptop occasionally. Was working OK before. All of a sudden it stopped working on this laptop. As mentioned, I tried another laptop (running Linux...) and it connected OK, no problem.

    Can you check lan settings on the other laptop?

    and resetting IP could help (type ipconfig /release and then ipconfig /renew at command prompt)

    Edit: and please disregard my previous post... I've mixed two topics - late here, have to take some sleep.

    Sometimes disabling and re-enabling network adapter can help. Also restart computer (if it wasn't for a long time)

    Any success ArchiMark ?
    That empty default gateway isn't good. You could insert your default gateway manually. Usually is the same number as yours, just with 1 as the last one (check on other laptop).While at it, set your IP address manually (just put in the same numbers as you have now).

    Thanks again for your help!

    Left work for the day. But took my little GPD WIN home with me to try on my home network.

    It connects OK to ethernet network here with no problem. Did not need to do anything.

    So, that is good sign that laptop/network hardware is OK.

    Now, need to figure out on Monday what is wrong at the office network. Will try your latest suggestions there on Monday.

    Thank you.

    OK, somethings to mention....
    There is a big difference if you are part of larger network at your office, or you have your own business and your network.

    If you are connected to large network, don't do any repairs on your own. Ask for network administrator and let him assist you. (to be on a safe side...)
    If your office network is like small business network and employees are also admins :) then:
    - check if problem is already fixed (could be provider problem)
    - reset router (power off, wait half a minute and power back on) and check if problem is fixed
    - manually set IP address (best in my opinion is to copy one of the working computer settings - you checked it yesterday - and manually set address to a hundred off - i.e. instead of 192.168.1.105 set it to 192.168.1.205) fill every settings including gateway and DNS

    I guess your cable is OK, since you have problem with wireless too. Just in case, check if cable is inserted into router or switch.

    If non of the above would help, you'll have to access you router settings...

    Thank you for your latest input. Very much appreciate it!

    Yes, connected to a very large network and it is very secure for variety of reasons. By large I mean many different locations across multiple states in US.

    I do have a group of IT people that work in office space not far from where I am located. Was hoping to avoid discussing things with them if possible, as they probably are not too happy with my using the network at times with my own laptop.

    Just strange that this problem started now after it was OK for a long time. Maybe IT changed some security settings?
