I set up a static/manually configured network as most of u suggested for all 3 machines and then created a LAn setup in router configuration.

You configured a static address, etc, on each machine? Then you do not need the DHCP setup on your router, especially the reserved addresses, because they are all machines with static addresses configured, right?
At some time, something like a phone. tablet, etc, will connect to your router and ask the DHCP server for its stuff. Whilst it won't give out any of those reserved addresses, it would be better to change the DHCP range to, say, 192.168.1.2
00 to 192.168.1.254
The only problem that i'm having with this is after a powercut generally the files dont play locally
I'm not at all sure about your interpretation of what is happening, but would need to be there. And I'm rusty on this stuff anyway.
and I have to again go into router settings, LAN setup and click on Apply to get it to work. Why do u think that's happening ?
Somewhere among the router pages will be a SAVE option. My guess is that that is what you are not doing!
After configuration, power down everything, start everything up again (router first of course) and test. Don't leave the testing job to power cuts!
There should also be a settings BACKUP option on your router. This will save the settings to your PC. Saves you typing it all in again if everything is lost. On this topic, I suggest that you take screen prints of all the config pages you have changed, especially the WAN (internet) connection details (and write the connection password on that sheet). That way, when you replace or upgrade your router, you have all the information you need to get connected to your ISP on the new router within a very few minutes.
