  1. Hi guys,

    I've been researching and trying to days to get this to work with no avail so I decided to post here for some help as I see this community is really active.

    We've got 4 different laptops here and none of them can connect to the wifi anymore (it suddenly stopped working for the last whole week). We can connect to the internet through ethernet cables though. We only use one at a time (if ethernet, then wireless is disabled and vice versa).

    Here is a copy of the ipconfig/all:

    You have an IP on your LAN, but none on your wifi. Check your router to make sure DHCP for wifi is turned on and you have enough available addresses.

    Disable the Ethernet if you want WiFi and disable WiFi if you want wired ethernet - - you can only One or the other but not BOTH ad the same time.

    Hey peterm777. Sounds like a router gone bad to me. I would power off all the pc's, then reset the router to factory specs. See if you can connect wirelessly to the default SSID of the router. If you can't, see if there is a firmware upgrade for your router. The firmware upgrade process only takes a few minutes and the process is not difficult if followed correctly. I had an older Linksys that the client and her ISP rep said was bad, and when I looked at it,it sure appeared dead. I had nothing to lose so I downloaded a firmware upgrade and applied it. It worked in both modes after that, so I secured it and haven't heard from her since (over a year).

    Hey guys, thanks for getting back to me.

    I could only get on the net using the ethernet cable at the time and I checked the wifi to make sure there is enough available addresses for the DHCP.

    I've tried that and still the same problem

    It seems that I may have a bad router, I'm not too sure. The router is a Netcomm NB304N, I did a firmware update and reset the router to factory specs. I then tried to connect to the default SSID and had problems with it initially but after a few attempts it worked for a bit and then stopped working.

    Another weird issue is that when I'm connected via ethernet cable only and wifi is disabled it still shows a yellow exclamation mark even though I can connect to the internet. In the diagnostic tests everything is a pass except for this:

    Test ATM OAM F5 segment ping fail

    Any thoughts?

    I would go for a new router (or maybe borrow one for an hour or so, I have seen a few fail). 4 pc's that lose connection is not a problem with the pc's, especially if it will work using Ethernet but no wireless connectivity on either machine. You could lose a wireless signal and the pc could still show you as being connected to your SSID, but a balloon with your cursor over your wireless icon should show no internet access.

    I am facing the same issue...can someone please tell me how can I disable the Ethernet because I want use my WIFI

    TheHawk TS Enthusiast Posts: 192   +7

    Hey OmkarPad. To use a Wi-Fi connection instead of using a "wired" (Ethernet) connection, just disconnect the Ethernet cable from the pc and allow the pc to view the available wireless network you want, then connect.

    Is the Wi-Fi connection you are trying to connect to your own and is it a secure connection?

    What do you mean by a secure connection, I don't understand..how do I know if the connection is secure or not? sometimes the wifi won't work on my mobile as well..is there something wrong with my wifi router? this is just a maze for me ...

    When you first got the router, or at any time since, was it setup by someone to secure it where a name was given to your network and a password was created that you had to enter to be able to access your wireless network? That is what"s called securing your network
    When you hold your cursor over your wireless icon in the system tray in the lower right corner< what is the name of the network shown?
