    Complex ethernet and wifi problems


    Hello, For no reason all of sudden, my ethernet connection isn't showing even not in network connections, neither in devices. Also my wifi keeps disconnecting.

    I tried reinstalling drivers, settings reset, restarts

    What I know that the problem is in pc sw/hw issue, bc i plugged the same cable in another pc and it worked fine, wifi is running on multiple devices just fine.

    Can anyone help me?

    WIFI Works, Ethernet won't

    OK but why?

    NOT YELLING, JUST EMPHASIZING

    Please note, I installed the new Lynksis, it worked just fine for 3-4 days on both my MACBOOK PRO when in ethernet connect and the Dell, then the ethernet just quit working for both my MacBook Pro and Dell desktop. It did work, then just quit for no apparent reason. WIFi for iPhone, iPad, Andriod Phone, and when I set to wifi for my MacBook pro all work fine.

    Detailed history: I first noticed that on my Desktop dell that is CAT5 ethernet connected to the WIFI ROuter, that it stopped, no internet access. I began to trouble shoot, and turned off my WIFI on my MAcbook and it wouldnt work either, plugged into same router but different cat5 cable. At that time, all WIFI devices still worked. I figured that it must be the ethernet side of the WIFI router, so I replaced the router with brand new one. the Lynksys N900 listed in original thread. Ethernet and everything worked just fine for 3-4 days. But then ethernet quit, but wifi still works.

    Whatever the problem, it affects both my MacBook Pro and Dell with WIN 7. I'm guessing it is NOT a computer problem, if it is it is affecting both my Mac and Dell, separate cat 5 cables to same wifi router

    To remixedcat, I don't know for sure how to check IP settings, see above post, no damage apparent to anything.

    IP configuration not valid - interference from ethernet adapter?


    Solution 1: No Internet Access In Windows 8.1or Windows 10

    Step 1:

    Go to Device Manager → Network adapters.
    Step 2:

    Expand it (Network adapters).


    Step 3:

    Select your network adapter


    Step 4:

    Right click on your wireless network adapter or Ethernet adapter and then tap “Update Driver Software”.
    (in this case your network adopter is Ethernet adopter so tap your Ethernet adapter)
    Step 5:

    Now on a new window you will need to click on “Browse my computer for driver software”.

    Step 6:

    Then select “Let me pick from a list of device drivers on my computer”.

    Step 7:

    Now choose the “Manufacturer’s drivers” from the list of two and then click next.

    Step 8:

    After the completion of the process just restart your PC and check if the problem is solved or not. If not, goto solution 2.

    Solution 2: No Internet Access In Windows 8.1,windows10

    Step 1:

    Open command prompt.
    Step 2:

    Just go on hitting the enter after typing the each command.
    netsh int tcp set heuristics disabled
    netsh int tcp set global autotuninglevel=disable
    netsh int tcp set global rss=enabled
    Step 3:

    Now to check if the settings are disabled type:
    netsh int tcp show global
    then hit enter.
    Step 4:

    Now the thing left is just rebooting your system and just check if the problem is solved or not and just give feedback.*chuckle*Thumbs

    Complex ethernet and wifi problems

    WIFI Works, Ethernet won't

    Fart

    Brandon,

    I don't know what I mean. YES ON WIF i can connect to the internet, but you cannot connect to anthing plugged into the same WIFI ROUTER with CAT5 Cable ethernet. My MacBook Pro has WIFI and ehternet, ethernet wont work, but wifi will. My Dell does not have wifi, and I cannot connect to the network or internet at all. As I mentioned, I changed the WIFI Router about a week ago, problem solved, for 3-4 days, now ethernet to the new router does not work again.
