How to set up a static IP with ethernet connected Mo0de?

[mikeburnsnz]

Hi there everyone.

Over the past year I have had a range of connection issues with moode over wifi. The main issue is around my router reassigning Moode a new IP address randomly which means I lose connectivity to the ui. For some weird reason I can login to Moode at the moment over 192.168.1.16 (latest randomly assigned IP address) but I cannot connect to it using my phone and the typical moode/

I have now connected my Raspberry Pi to my router using ethernet as it seems to be a more stable connection but I still get the IP address changes.

What is the best approach to setting a static/stable IP address with moode? I have read reports of people doing it with their routers and leaving Moode on DHCP. I have also read of people doing the same but with Moode and not their router. I always thought you set up a static IP with your router and then added those details to Moode?

I am a bit confused but really just want a stable, reliable connection to the UI.

Would love any advice or setup approaches that get a stable, reliable connection.

Thanks

Mike

What model Router?

What model Router?

It is a Netcomm NF18ACV. Provided by our internet provider so not a top of the range one for sure.

I set up static IP on both RPi and on the Netgear router. (3 wired, 1 wireless)

When u setup a DHCP address reservation in Router you should leave the Pi set to DHCP. When it boots and asks Router for an IP address the Router will look in its DHCP reservation table for a matching MAC address and then assign the corresponding IP address to the Pi.

If you just set a static IP address on the Pi and don't also exclude it on the Router by limiting the range of DHCP addresses the Router can assign there is a risk that the Router will assign that address to another client and then you end up with an IP address conflict on the network.

I just downloaded and skimmed through one of two Netcomm NF18ACV User Guides I found online https://support.netcommwireless.com/api/...0Guide.pdf)

The good news? This looks to be a very capable device which exposes tons of settings in the UI. The bad news? The user guide reads like an encyclopedia and takes concentrated effort to find what you want.

In the specific 96-page guide I downloaded, the setups needed for the two options that Tim described can be found on pages 66 / 67. These fall under Advanced -> LAN -> Local Area Network IPv4 in the table of contents.

On page 66 is described how to set the "DHCP start range" and 'DHCP stop range". On page 67 is described how to the "DHCP static IP lease facility" to reserve DHCP addresses for specific hosts.

Either method will work; I prefer using DHCP reservations so that all the other details like gateway and name server addresses are set in the client automatically. YMMV.

ETA - "Ethernet" is in the subject line of the OP but it discusses WiFi. These address assignment options work with either but the MAC addresses will be different for the two interfaces on the connecting hosts.

OK thanks everyone. So just a simple question. Would I limit one IP address in the range on the router or would that mean all devices connected would be vying for the same IP? Or would the limited IP range just apply to the raspberry pi?

I am connected via ethernet now as I also have a wifi booster which meant that when connected on the booster I then could not access the raspberry pi ui (one of the previous issues rectified by the ethernet connection).

Something like below as an example of how Router DHCP address pool would be configured to exclude a range of IP addresses for either DHCP reservations or client static IP addresses.

# Set aside 25 addresses from the DHCP pool
- DHCP pool start address = 192.186.1.26
- DHCP pool end address = 192.186.1.254

# Addresses in the range 192.168.1.2 - 192.168.1.25 can be used for either DHCP address reservations or for client static address assignments.

As a footnote to Tim's last post, many routers allow one to reserve an IP address within the DHCP address pool. 

In his example above, such an address might be, say, 192.168.1.40. While this will work most of the time on a home network it leaves the door open for unexpected network behavior. See, for example,

static mappings inside DHCP pools

for an explanation.

A side note and observation...Fritzbox routers hand out an address when a device is first connected and then reserves it automatically.
This makes it a breeze to use. :-)
