![]() If all goes well you will see the following screen: Screenshot of Netgear WNR1000v2. The default Netgear WNR1000 IP Address is: 192.168.1.1Īfter entering the IP address of your router you can simply press enter. Find the address bar in your router and type in your router's IP address. It should look something like this: Browser address barĪbove is an example of what a web browser address bar looks like. Open up your web browser and find the address bar. It usually does not matter which browser you choose to use. This can be either Chrome, Firefox, Internet Explorer, or Edge. Your router has a web interface, so you will login to it using your web browser. Now we are going to login to your Netgear WNR1000 router. If you do not set up a permanent IP address in your device, then when you device reboots it may get a new IP address. This step is important because you want a permanent IP address in your device. Or, manually create a static ip address with our Static IP Guides.Another way to get a permanent IP address is to set up a DHCP reservation.Recommended - Our free Static IP Setter will set up a static IP address for you.This ensures that your ports will remain open even after your device reboots. While( UDPSocketInfo.It is important to setup a static ip address in the device that you are forwarding a port to. So modify the dchp code to pad out packets if they are not = or greater than 300 octets.Īdd this to the end of dhcpsend function where you see the //End of Options And as it is from the site so it can be taken as accurate. I found this on the internet it says that the mimmum packet for a dhcp / bootp packet SHOULD not be less than 300 octets. I haven't come across the problem of needing to pad the DHCP request packet though. Adjustments to the applicationĪnd its allocation of buffer memory bandwidth mayīe necessary if BUFER errors are frequent or Set BUFER are generally transient in nature, and do not The third condition (insufficient RX memory bandwidth)Ĭan be identified by checking if the BUFER bit Once processed, the application should clear the Space” for more information on processing packets.

The other thread I linked to above seems to have the exact same problem with an Airlink, but the solution was to find another router and nothing was posted about an actual technical solution to the problem. One is obviously longer than the other, but I don't see any particular reason why the MAC layer of the stack will just completely ignore one over the other. cap) for both the Netgear router in question and a Linksys router. HOWEVER, I know this function works with outher routers (even other Netgear routers). Which means that the timeout value in DHCPTask() always gets tripped and the PIC and router get stuck in an infinite loop of Discovery. By completely ignore, I mean that the call to MACGetHeader() in StackTask() after the DHCP part (technically the whole line is while(MACGetHeader(&remoteNode.MACAddr, &cFrameType)) ), doesn't register the DHCP offer message. This is an extension of the issue discussed in thread:īasically the issue is that with a particular Netgear router, the DHCP offer from the router is completely ignored by the PIC (I'm using a PIC18F67J60).
