    Unhappy ethernet not working but wireless fine

    ok. So i have win7 professional 32bit on my laptop, and use the wifi fine with that.
    got win7 ultimate 64bit on my desktop, and was using the ethernet fine, but then i didnt use the system for like a week, and then when i came back to use it, it failed to recognize the lan

    so i went to the modem settings, 192.168.1.1, enter the user pass of admin, admin and when i went to diagnostics, it shows clearly that the lan ports are not working...

    Hi

    I would suggest you to check your Ethernet Driver first. Uninstall any existing ethernet driver and then let Windows re-install it with stock drivers. Ethernet failure happens mostly due to bad drivers or conflict. Second you can use system restore option and select last restore point (if any) this will also fix the issue.

    thanx for the quick reply... @anand

    well i kinda figured that could be a problem, i did check that out... removed all the drivers and reinstalled them... but the same thing on two systems? i also have another desktop, which stopped functioning with lan as well. so i dont think the driver could be corrupted in both.
    i think it has something to do with my modem or its settings...
    its a wifi modem... Dataone.. WA3002G4

    system restore.. hmm well i kinda formatted my system, cuz it was after the exams and wanted to do a fresh install of windows anyways.. but the lan was not working even before i did the format... so i doubt that had anything to do with it...
    so.. still hoping for a solution..

    Is the subnet mask 255.255.255.0 in your LAN Settings of your Router Settings?

    Yes. It is the same, just as you said.
    255.255.255.0

    only problem is this in the diagnostics
    Test your ENET(1-4) Connection: FAIL

    it used to be PASS... but when i checked it a few days back... it kinda just stopped... :-/

    Create a LAN between your Desktop and Laptop using the RJ45 cable that you use to connect the modem with the desktop. If its fine, then the Ethernet port on your Modem is damaged, and if it does not work, try other cables. Its definitely a problem with the cables or the Ethernet port on the modem. Also cross check whether the RJ45 cable is plugged into the modem or not, i say this because you mentioned that you were away for about a week, who knows you might have had unplugged it before leaving and now foul playing with the other end!!

    hmm, well i tried to create a connection between the laptop and desktop...
    it came as unidentified connection.. i think i had to change the sharing rules and ip adressess and stuff.. im not sure how that works...
    but it did recognize that the cable was connected at both ends... and unlike when i connect the desktop to the modem, it recognized and stated no internet access... if its just the desktop to the modem, it is constantly trying to recognize the connection and never stops.

    i dont think i did the lan connection properly.. so if there is a step by step instruction on how to connect the laptop to the desktop through the LAN cable, it wud be much appreciated, so i could do it properly and then give a more elaborate and proper feedback

    also i was only able to ping the desktop from the laptop and vice versa properly only after deactivating the windows firewall on both systems.. so if i could know the respective settings for the firewall that would be great too..


    i checked if the cables were loose or nything, but they were all fine.. even got new cables to check, but no change
    was worth a shot

    ethernet ports damaged?
    then i'l have to ask bsnl for a new modem which will take forever... :-/
    i sure hope its not the ports... i'l have to buy a new modem in that case..

    so i ran some other diagnosis from the network adapter settings.
    hardware diagnosis is all passed
    EEPROM test - passed
    FIFO test - passed
    Register text - passed
    Loopback test - passed

    in d cable management
    polarity - normal
    but cable offline test -failed.

    and in connection diagnostics
    connection test - failed
    this connection is configured to use a static ip address... (i did do that tryin to create the LAN)
    no WINS server is available for this connection
    no DHCP server is available for this connection
    ping gateway 192.168.1.1 failed
    ping DNS 192.168.1.1 failed
    ping DNS 61.1.96.71 failed
    Auto negotiation is not complete on this adapter...


    so im guessing its not the cables... but sumthing to do with the router or system settings...


    also.. i did manage to bridge the connections on the laptop with the lan.. so i can share files.. but just not the internet..!! i can ping both systems now that the firewall is down... but i still cant access internet on the desktop.
    its just at Unidentified network - no internet access


    just to be sure.. im going to get the modem checked tomorrow morning..!! will go to the exchange and see whts up...
    will see if its a problem with the modem or not..!!
    hopefully it is, so i can get it rectified asap

    heres hoping for the easiest and best

    ^^That is enough to prove that your cables and the NIC of your desktop and laptop are okay. Be sure that the Ethernet port of your modem is damaged. Contact BSNL.
