![]() ![]() Verify you have connectivity to the IP address of your IP webcam: Note these commands should be the same/similar across Windows, MAC or Linux. Then open a terminal or Command Prompt window, and run these commands. Reboot your IP webcam so that it will be accessible. If you cannot access the IP webcam easily, then instead you can determine the MAC address from your PC. Note that each network interface has a different MAC address - so there will be one for the WiFi network, and one for the Ethernet network. This is normally printed on the device itself, and will be in the form AA:BB:CC:DD:EE:FF, or AA-BB-CC-DD-EE-FF. You need to know the MAC address of your IP webcam. Therefore you could allocate a static IP of 192.168.1.200. For example this device is using the range 192.168.1.1 to 192.168.1.100 to dynamically assign to devices. To identify the configured IP address range used by DHCP, you will need to refer to your modem/router. Make sure the IP address is not in the range that might be assigned to other devices. The IP address is normally configured in the IP webcam settings, though you can get fancy and get your router (DHCP server) to always assign the same IP address. This is referred to as a static IP address. Since we'll use a fixed mapping from IP address to MAC address, you will need to use a fixed IP address for your IP webcam. If you make the IP webcam directly accessible via the Internet, then the change would need to be applied to your modem/router. If you have a NAS (Network Attached Storage) device that records from the IP webcam then you need to apply the fix on the NAS itself. If you simply do so from the family PC, or laptop then you need to apply the fix there. ![]() The modem/router cannot respond to ARP requests sent to the IP webcam, the IP webcam must respond to these.įixing the problem needs to be done on all devices that will communicate with the IP webcam. However clients will still lose communication with the device once it ceases to respond to ARP requests. A static DHCP lease means the device is granted a fixed/static IP by your modem/router (based on its MAC address). TIP: A static ARP entry must not be confused with a static DHCP lease. Instead, the IP to MAC translation is successfully performed and the request packet sent to the destination. In this case you never need to ask "who has this IP?", because it is known in advance. When the IP webcam stops responding to ARP requests, you're in a situation where your client (PC/NAS etc) says "who has this IP?" and simply gets no response.Ī static ARP entry is a fixed mapping between an IP address and the device MAC address. The ARP protocol allows a network device to discover the MAC addresses of the peer device with the designated IP address, therefore allowing communication. It underpins all IP communications over both Ethernet and WiFi, since at the lowest level it relies on exchange of packets between device MAC addresses. It turns out the problem is that the webcam simply ceases to respond to ARP (Address Resolution Protocol) requests (once in this broken state).ĪRP is a mechanism to translate between IP addresses and device MAC addresses. I've tried disabling DHCP (router based static IP). The problem is not related to my browser or the wireless network. I've tried upgrading to the latest firmware (version 11.14.2.17 is supposed to fix WiFi disconnection problems), but it did not fix my problem. Power cycling the camera would fix the problem. However, I've had problems with being unable to connect to the camera after a period of time (an hour or so). I bought a FOSCAM FI8908W wireless IP webcam off eBay recently. ![]()
