  1. Wifi Devices connecting to the wrong subnet


    I just installed a Dlink DIR-890L and it is setup to assign devices to the range 192.168.1.1 to .254

    However, it seems that when most of my devices connect they are ending up with an IP address that is 192.168.0.something.

    This is causing the device to be able to connect to the router but not to the Internet. It has happened with my laptop, 2 cell phones and wireless thermostat. I have no idea why. Right now I am going into each device and changing the default IP and then manually changing its gateway to 192.168.1.1 (it's also coming up wrong)

    I have no idea why this is happening.

    I see this in the router settings but there is no where to change the default gateway but I'm not sure if I need to and so far I have been changing it to 192.168.1.1 on all the devices that I have to manually configure/

    Any suggestions?

  2. Hosted Network Problem

    I have a hcl laptop with a 801.1n wifi driver, hosted network supported

    I had a good time using it but since last week when so ever I use hosted network service it gets started with internet access but when I connect my devices they get connected but without internet, all my three phones, other laptop, Tv all the devices are
    not able to get internet access.

    MORE INFO :

    I have a win10 pc

    I have set ip address of virtual wifi driver 192.168.137.1

    subnet mask 255.255.255.0

    default gateway "blank"

    dns 220.226.100.40

    My device (phone)

    ip 192.168.137.46

    subnet 255.255.255.0

    default gateway 192.168.137.1

    dns 220.226.100.40

    My device (phone 2)

    ip 192.168.137.29

    subnet 255.255.255.0

    default gateway 192.168.137.1

    dns 220.226.100.40

    My device (phone 3)

    ip 192.168.137.100

    subnet 255.255.255.0

    default gateway 192.168.137.1

    dns 220.226.100.40

    none of my devices get net access but on pc (windows), I can see hosted network access type: internet

    My internet "blue screens" when my desktop does.

    My network is setup as follows:

    1. ISP router running DCHP/DNS, wired to IPTV box & my router. Subnet 192.168.0

    2. My router running WiFi. Ethernet connections to desktop PC & server. External address acquired via ISP router's DHCP, Internal subnet 192.168.1

    3. Server running DHCP,DNS, etc for the 192.168.1 subnet.

    4. Desktop PC connected by ethernet

    5. Laptops, tablets, phones connected via WiFi

    Here's the weirdness: If my desktop PC blue/green screens it takes the whole network with it and I can't figure out why.

    The local network works fine, but any outgoing connection trying to reach the internet never makes it. WiFi connected devices show as connected with no internet. Ethernet connected devices show all is normal but cannot load any sites. Once I reset the desktop,
    all returns to normal as if nothing happened.

    The behaviour suggests the internet connection is in some way dependent on the desktop, but that's all on the server. Eveything is fine when the desktop is off, so clearly no dependence. Yet the problem persists. The problem extends beyond the local subnet
    as it takes down my IPTV connection also, but neither subnet is directly affected as I can still reach every device on both subnets.

    The issue started with Windows 10, from the moment I upgraded from Windows 7. I have clean installed many times since (2-3 times/year usually) to no avail. I have looked at the dump file and it seems to happen for a wide range of crashes (apps, drivers,
    windows kernel, memory). Not all, but no particular pattern has emerged allowing me to narrow it down. The condition is unique to my desktop, no other devices, wired or otherwise, cause this to happen.

    Any help/advice is appreciated.

    Hi superwindow.

    I would change the start of range to 10 or even 25. I leave a few in case I have to set a printer to a static address.

    Once change you must save. As soon as you save, if it took, according to your manual, you will become disconnected.

    I would reboot PC and reconnect.

    Edit: Obviously there are lots of panels before this. Have you confirmed their entries?

  5. I think after some reading I have found the cluprit, I just don't know how to fix it. In the bottom picture of my first post I see my IP address is 192.168.0.1 this is in the DHCP table of my ISP's modem/router, but I think what I want here is my external IP.

    So my guess is I need to change a setting in the ISP modem but I am not sure what I want to change? Do I turn DHCP off, or go to bridge mode?

    Here is the settings in the ISP modem/router

    Your last picture says that you're looking on the LAN side of the modem/router.
    Your external IP will be on the WAN side. Just change the tab on top. It will show IP that your ISP gave you.

    Your other questions aren't too clear at his point because you did not describe the wiring. Which port on the new router (LAN or WAN) is connected to which port of the modem?

    If things are getting the wrong ipi ts being picked up from another dhcp server ie the modem thats whats giving your problem. What logs into the isp the modem or router in most cases the modem just connects but the router logs in

    Got it figured out, I called my ISP and they remotely changed their modem/router to bridge mode, so far so good.

    Do you have the ISP's router connected to the WAN side of your Dlink, If the pictures I seen on Google are correct the WAN side of the D'Link looks yellow, This is important even now as your ISP's router is in bridge mode.

    All your other devices connect to the LAN side of the Dlink which are all black.

  10. OK thought I had it figured out, but I reset TWO computers that are hard wired to the router and both got assigned an IP address that is 192.168.0.XXX

    I have no idea how this can be happening. Only think I can think of is that I changed dlink from being in the 192.168.0.XXX range to the 192.168.1.XXX range and maybe there is a glitch in their firmware.

    The router isn't actually in bridge mode, but IP PASSTHROUGH mode, and it is passed to the MAC Address of my dlink router, not sure what else I can do??

    The IP Address of router is now showing as my external IP address so the passthrough is working correctly.

    As mentioned above in an earlier post do not set your DHCP from 1.1 to 1.254 if you don't have many devices set it from 1.100 to 1.199

    Also as mentioned above have you pressed the save button after you made changes to the Dlink

    Also did you check if your lan cables are connected properly as was mentioned above.

    It's also a good idea to reboot your Dlink router after making major changes.

    You can reset your lan card by following this tutorial written by Brink.
    Reset Network Adapters in Windows 10 Windows 10 Network Sharing Tutorials

    I would also see if checking Always broadcast located in your DHCP server settings.

    If all that does not work Reset your Dlink back to factory defaults, Then try changing it back to 192.168.1.1 if you want.

    Looks like you had two devices running DHCP. First come first serve is how it works. So your "modem" was still acting as a router and DHCP server. Bridge mode stops that.

    Regarding the scope. You have it set from 1.1 to 1.254, you can change it but honestly it makes no difference. The protocol has mechanisms to avoid duplicate addressing and not worth the hassle tweaking.

    Regards,
    Josh

    I did all the above steps, checked cable, adjusted DHCP table, etc.. and still some devices are getting 192.168.0.XXX even after the ISP router/modem is in IP passthrough.

    Maybe time to factory reset and just go wtih 192.168.0.XXX

  14. Shadowjk suggest in his first line, set ISP router to bridge mode. Have you tried this?

  15. I can't in the settings, and when I called my ISP they said they only do that for the super expensive Internet package; however, they walked me through setting up IP PASSTHROUGH which disables the DHCP on the modems end.
