Able to access my IPCAM under LAN Cable but failed via WIFI

ohlalayeah
My config first:
1. Router is Buffalo WHR-HP-G300N
2. IP Cam is Wansview NCM620W (supports LAN and WIFI)

My router has been configured DDNS and opened port 8004 for my IPCAM.
I am able to access my IPCAM where it is connected via LAN cable using my own domain name of DDNS, I also can access IPCAM via GPRS with my mobile phone app (IP Cam Viewer). However I cannot access my IPCAM using DDNS when it is connected to my router via WIFI with my mobile phone app and PC.

So what is the difference between LAN cable and Wifi connection of my router with my IP Cam?? Thanks!

    Hi

    When you connect via Lan cable you may get ip address (ie 192.168.0.10) and the wireless connection may be picking up a different IP address. therefore you dont see it. if you set the Camera for DHCP

    As for the GPRS the routers firewall fwding rule may fwd the communication to that IP the cam has when connected via ethernet, but not the wireless IP.
    Did you set a static ip on that camera for both interfaces? or you can grab the MAc addresses and do a reservation in your router to always assign the same IP.

    Thats my first guess as to why it would not work.

    The question, of course, is if you can ping the camera over wifi or not, which would tell you if it had the wrong IP address.

    The access and forwarding rule for sending port 8004 may only apply to the wired interface....you may need to delete that rule and create it for the device when it's connected wirelessly.

    While the wireless part of the device should act like a mac-layer bridge, sometimes there can be a security feature or bug that creates issues.

    To be clear, there is only one router involved, not a router hooked up to a DSL router??

    Thanks for your reply. Yes, I only have 1 router with a DSL modem. The connection is IPCam ~ Router ~ DSL modem ~ Internet

    I can only set one IP address for my IP Cam, so I guess the IP address is assigned to the ethernet interface of the IP cam and thus even I have done port forwarding, the router only forwards external connections to the ethernet interface instead of the wireless interface of my IP cam.

    My router is 192.168.11.1 and IP cam is configured with IP: 192.168.11.24:8004.

    Hi,

    I also have ipcam's each interface should get its own ip address by default, unless theres a setting that is overriding that (the wireless device has specific MAC address and the Ethernet interface has one., I would double check the manual as confirm how to check the wireless and wired interfaces.

    Hi Mark,

    Which model of IP Cam are you using? Please let me know once you get how to check & modify the IP address of its wireless interface. Thanks!
