I can't connect to wifi but connect with an Ethernet cable works, even when it isn't plugged in

  1. I'm a new Plusnet customer and I cannot connect to the internet using wifi I just get a page saying the broadband is down. So I tried using an ethernet cable and after manually setting this up I can use the internet. I accidentally disconnected the cable yesterday but the internet didn't fault, it's now working wirelessly. I can connect to the wifi using my mobile and iPad but I cannot connect to the internet. A new router has been sent and the problem still persists, a bt engineer has also visited but cannot find a solution.

    Can anybody please help me?

    It gets confusing as to which device is being used so as a guideline
    disable one or the other (wifi vs wired) and don't allow both to be active at the same time. Technically, which ever device gets an IP address from your router will become the gateway to your ISP - - ignoring the connectivity of the second device to access your router.

    With a laptop, we just toggle the keyboard to enable/disable wifi and the wired is easy - - just pull the cable out.

    create a desktop shortcut to \windows\system32\devmgmt.msc
    to control the devices (needs admin access)
    expand [+] network adapters and you'll see the list
    mine are
    • Dell Wireless 1502 ....
    • Realtek PCIe FE Family Controller
    Just right-click->disable and you can always right-click->enable

    The png posted shows both are enabled and the wired has the gateway.
    If the cable is disconnected, this is quite impossible.

    SO, first control which device is to be used and then make the connection.

    I have tried disconnecting both, when I disable the wireless I lose the wired connection as well. When I disable the wired I still cannot connect to the internet via wireless. I get this screen. All of my other devices also get this screen when trying to connect to the internet via wireless.

    I have followed the instructions on the screen, nothing changes m.png

    Leave the modem/router alone - - disable the wired connection by removing the cable which is connected to the pc AT the pc end.

    Look in the SYSTEM TRAY for this
    upload_2014-9-1_14-30-33.jpeg
    you connect via this icon to your wifi SSID

    and once connected with your password, you can use ping to prove connectivity; get a command prompt and enter
    ping google.com

    I have just tried that and the 'broadband not connected' screen appeared again. n.png

    I Assume you connected to your SSID on your router - - but did you?

    get a command prompt and issue
    • ipconfig /all >mytcp.txt

    copy the contents of mytcp.txt and paste into your follow-up

    I connected to my SSID yeah, when I try and run the prompt, the box loads and closes before I can copy anything

    It is INSIDE THE FILE mytcp.txt :)

    Don't close the command prompt where you ran IPCONFIG

    it's right there :)

    C:\Users\Jeff>ipconfig /all >mytcp.txt

    C:\Users\Jeff>dir mytcp.txt
    Volume in drive C is WIN7-OS
    Volume Serial Number is 7C4E-86D4
    Directory of C:\Users\Jeff

    09/01/2014 03:48 PM 4,064 myTcp.txt
    1 File(s) 4,064 bytes
    0 Dir(s) 302,259,728,384 bytes free

    C:\Users\Jeff>​

    use NOTEPAD mytcp.txt to get the data :)

    I'm trying to run the 'ipconfig /all >mytcp.txt' command prompt, but the window instantly closes itself. Is there anyway you can take remote access?

    Hmm; start->run (or search) enter CMD and hit retrun

    Your saying it dies immediately, when you enter something, or when that something completes?

    run->cmd and enter DIR just has to work buddy...

    GOOD - - Now you/I can see the issues (click to expand these quotes)
    This connection has you boxed in and inhibits the wifi which follows
    and the wifi connection is just fine.
    You must disable PPP adapter Broadband Connection 2

    I went into properties and disabled it. Disconnect from everything, reset the router and then connected to the wireless and I'm still getting the same screen.

    I've had to reconnect to the wired to get back online

    The C.PNG defines your problem - - the VPN should not be active or connected.

    Q? is your ISP service using that connection? It looks like it's a dial-up / VPN and you should not need that.

    Did you setup the WiFi router or someone else do that for you?

    Let's see what TCP thinks of all of this.

    Connect the VPN AND get the wifi connected too.

    Get the command prompt and enter ROUTE PRINT >myroutes.txt

    access it via notepad myroutes.txt, copy the content and paste it as your next reply

    The modem for Fibre Optic was set up by an engineer, but the router just set itself up automatically

    I can't make this easy to read using columns, so we will just have to struggle with it:

    In the IPv4 table
    1. Network Netmask Gateway Interface Metric
      Destination
    2. 0.0.0.0 0.0.0.0 192.168.1.254 192.168.1.64 4250
    3. 0.0.0.0 0.0.0.0 On-link 87.114.194.38 26
    4. 87.114.194.38 255.255.255.255 On-link 87.114.194.38
    5. 192.168.1.0 255.255.255.0 On-link 192.168.1.64
    #5 shows your local lan IP= 192.168.1.64 and everything on the lan is reached using thus link (192.168.1.0 255.255.255.0)

    #2 is the network default route; unless there's some other entry in this table, everything should go thru this path to your router at 192.168.1.254

    #4 is the Broadband VPN; and this line says applications must access this directly

    #3 is BAD NEWS
    0.0.0.0 0.0.0.0 On-link 87.114.194.38 26
    is another default route to the VPN -- this is a multi-home configuration.
    The last number (26) is called the cost or originally the hop count for this link.
    As 26 is lower that the line#2 4250 value, line 4 will win and all data goes to the VPN rather than you lan router.

    Getting your router to have precedence is a problem.

    Normally, we don't create a VPN link until we need it, and thus the Broadband connection would not appear and you would not see this issue IMO.

    Frankly, it drives me into a tizzy when you comment it works even when disconnected - - obviously that is literally impossible, so I conclude we are not communicating and the entire setup is not well define in this discussion.

    I'm at a loss on how to continue - - - sorry.
