Fixed IP address on wireless network?

[lupedelupe]

Hi folks,

I am a complete moron when it comes to the tech of networking. I currently run up to 8 devices on my wireless network. Most are fine, except for a printer which tends to give a LOT of problems (more about that another time).

I want to try and run fixed IP addresses on the network to see if this solves the problem.

I use a Netgear DG834GT router. I understand that I can assign a fixed IP address through the LAN IP Setup menu, but it rejects my input claiming that "IP Address is illegal!". And that is more or less where the world of tech lost me. For what it's worth (have no idea if this is relevant or not) NAT is enabled.

Any help will be hugely appreciated. Thanks.

You'll want to go into the DHCP server portion of the config, and reserve an IP for each MAC address that is connected.

Just give the printer a static IP in the scope of your DHCP,but outside the range of IP addresses that would dynamically be assigned,presto

Thanks -

That's what I thought I did wtf: have Use Router as DHCP Server checked; and used an IP address with the range indicated?

On the printer,manually configure IP

And post the settings you put in there,i think you may have erred with the subnet mask or IP

I agree, configure an IP reservation in your DHCP pool against the printer MAC address.
End-devices shouldn't be configured with static IP addresses.

+1 Also check you are within the range you have setup on the DHCP, you might have only allocated a small range like XXX.XXX.X.1 to maybe 10 ?

I have managed to set the IP address using printer software. So will see how that goes ...

Just wondering how to do the same for, as an example, my iPad? I can punch all the numbers into the iPad (under Network properties - changed to Static rather than DHCP), but it then loses the connection.

Yep: have checked that the numbers are within the range indicated by the DHCP listing.

Re the "IP Address is illegal!" message: I see that the router software/interface should list devices eligible for 'Address Reservation', but it doesn't list any of my devices?

I have set this up before on that exact router.
Your best option is to:

1) Set the router to handle all IP allocation
2) Set each device to acquire an IP automatically
3) Set the router to assign an IP to each MAC address.

Whenever you add a new device, it will be given an address from the remaining range, and then you can fix that MAC to an IP.

If you are really stuck and can't make a plan, let me know, and I'll get the router out the cupboard, and take some screenshots (was a great router, however it got hit 3 times by lightning, and each time a LAN port on the router broke, so now it only works for WiFi)
