I have just hard-wired my Philips to my network/PC

Worked first hit - great - Video Pictures Music great

Next day could not find the network (My PC was awake) - 12 attempts I gave up - Switched off TV and restarted it and it connected straight away

Next Day the TV can see my laptop (on same network no media files) but not my main PC (which is most certainly awake) - switched TV on/off loads times no joy

Any clues how to get stable connection with Philips TV?

Tried the option to use fixed IP - is that better or worse?
