Using a Static IP Address on a Raspberry Pi Connected to my Nighthawk Router
Hi,
I have a couple of Raspberry Pis connected to my Home Network which is provided by my Netgear Router. Ideally I want to set up a static IP Address for each of these Pis, but I cannot make them 'see' the Internet reliably unless I use Address Reservation in LAN Setup page. This works, but it means that I can only have the IP Address that the Router gave me through DHCP before I reserved it. What I really want is to specify static IP Addresses in the 'dhcpcd.conf' file on the Pis and have the Router accept these as the addresses to use.
I'm sure that I was able to do this in the past, but not any more.
Also. If I reserve the DHCP Server on the Router gave me, I'm sure I used to be able to edit this to the IP Address that I want but this also causes the system to fail. (For info. The Router assigns the address and I can connect to either Pi using SSH via the LAN, but the Pis can't see the Internet.)
Is there a way to do this?

The router was unaware of the presence of the Webserver, so didn't route Google traffic when I was trying to use the Static IP.

Configure the Raspberry Pi staticly. That means going into the Pi and assigning an IP address, mask and gateway. Make sure the IP address is outside of the DHCP scope on the router to get things to work. I have 2 Pi's setup this way. One is running Pi-Hole.
If you need help with the assigning, Google is your friend. Lots of Pi info there.
'Configure the Raspberry Pi staticly. That means going into the Pi and assigning an IP address, mask and gateway. '
I have been configuring the IP address statically, eg:
# Static IP configuration: interface eth1 static ip_address=192.168.1.98/24 static routers=192.168.1.1 static domain_name_servers=8.8.8.8 metric 200
What do you mean by 'mask and gateway' in this context?

I suspect when you did the actual configuration on the Pi you were asked mask. That does not show when doing the command you gave.
Normally when doing the actual assignment there is a mask question. Is the .98 address within your DHCP scope? If so that can cause issues.
Can you ping the Pi? If not then that would be where to start assuming the .98 is outside of the DHCP scope.
If you do a ifconfig eth1 you should see the mask. Here is output on my Pi.
ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
