Suggestion for LAN IP address

Ok, got it working with just a cable between PC and home theater.
Having done that, wanting to experiment with manual IP settings, I can no longer get the PC to see the LAN router!!
My problem is solved for the moment. If I ever need more than 1 device I will just have to pull Ethernet cables through the roof-space.
Thanks for the help.

OP mentioned he could ping ADSL router (wireless connection) so most likely they work together (post #6 last paragraph). However, hmm, maybe an incorrect DNS entry coming from the DHCP of wired connection.

Can you "ping 8.8.8.8" for example?

Thanks. I did read that - but I did not do a good job of keeping the layout of things in my head. (e.g. ADSL = wireless).

Macnab, good to hear that. If you don't mind working a bit more, we should be able to get your system working while having router in between, that would allow you to add additional devices if you so wish). I am with Barman here regarding how to setup the network but don't mind helping out with current situation.

I used a different network ID when giving you the example. Remember your LAN router has 192.168.0.0/16 (255.255.0.0), I told you to use 192.168.2.0/24 (255.255.255.0). The 16 and 24 are another method of showing subnet mask.

You can try:
- change PC cable IP (last number -10- is for the sake of example) to 192.168.2.10/255.255.0.0
- you should be able to open LAN router interface now
- if possible change LAN settings of the router and change it to 192.168.2.0/24 (255.255.255.0)
- if you can't change router LAN segment/IP etc, then change the IP of Home Theatre only (PC should be ok now)
- also disable DHCP of LAN router while you are in management interface (important step)

In short the idea is to disable DHCP on LAN router and have IPs from the same network ID/same subnet for the router and your two computers

I did experiment along those lines earlier. I have since done a lot of experimenting.
It is now working, DHCP off, router at 192.168.2.1/24, PC (static) at 192.168.2.100/24, home theater (static) at 192.168.2.101/24.

If I set the PC to 192.168.2.10, then streaming fails. I now realise that there is a limit with the router - if DHCP is switched on it only allocates from ...100 to...199.

So, problem solved, can add another 2 devices and have Internet. Thanks again.

Good job :) I am intrigued to learn why 2.10 fails but it would be a pain to troubleshoot without actually browsing the router management page.

I think the router is just designed that way: DHCP only allocates ...100 to ...199. Ignore the x.x.x.0 subnet. :) Has some sort of internal filter.

I'm a moron - the start end end DHCP range is a setting. Why it defaults to that range they don't say.
