Is the windows computer within that range as well? If not what happens when you put it within that range.

No, all computers are on DHCP. I will try putting it in there soon.

ummmmm, 192.168.1.200 doesn't work but 192.168.1.201 works. It must be something with the router then.

It would still be nice to see the output of ifconfig

Can we also have the output of arp -an

The output looks ok.

If you just want this fixed ASAP, I'd try rebooting the router.

If you want to find the cause or reboot does not work then, can we review what we know, please correct as required.

2 linux boxes, one windows box and one router (and some other stuff from the arp).

When any of the three boxes use 192.168.1.200 it does not works
When any of the three boxes use 192.168.1.201 it works.
When any of the three boxes use 192.168.1.204 it works.

Is there any wireless involved here?
Are you moving cables or ports as well as changing IP addresses
Is there a firewall on the router?

2 Linux Boxes on 192.168.1.200 and 192.168.1.201
2 Windows 8.1 laptops on 192.168.1.3 and 192.168.1.5
Nexus 5 on 192.168.1.7

The 2 laptops and Nexus 5 use WiFi. Not moving cables. Think there is a firewall. I tried to factory reset the router but didn't work.

if you swap a windows laptop for the linux boxes does it work ? ie

if you take a windows laptop and connect to the ethernet cable used by the linux box 192.168.1.200. use ethernet not wireless and set ip address to 192.168.1.200 does it work ??

likewise other linux box ?

Hmm

After the reset 192.168.1.200 seems to have started to work again. I will try some of the suggestions here if it stops again.

Thanks for all the advise guys!

If the issue comes back I'd try swapping a known working box with the box with the issue. If the 'good' box has an issue, post on the LAN forum.

Are you using the switch in the netcomm and its wifi, or just using it as a router? Sounds similar to the hair pulling hassles I have had with them in the past with things disappearing off the lan. Seems its bridging between the ethernet ports, and also to the wifi gets flakey and will stop working. Powercycle and everything comes right for a few weeks.

Yeah I'm using the switch. I would like to get a better router.
