Kryptview box probs

Hi i have kryptviesw box in living room downstairs, PC with modem and wireless router upstairs bedroom, cable for internet runs through house to living room, what do i do to link it all together, ( please make answer easy to understand) do i need another cable (Rs232) (really stuck) Thanks

It as before cable TV lead from wall to box.
Also
A ethernet cable from router to box (same type of cable thats connects modem to router) https://dooby2oons.forumotion.com/kryptview-f18/cable-for-kryptview-t2191.htm#11777
Or
"Home Plugs" they use the electric circuit cables in the house.
Router - Home Plug (upstairs) Home Plug (downstairs) - box
Two "Home Plugs" are needed,they plug into the wall socker in the house.

Thanks very much, i understand now will buy 2 home plugs, just wondering how the information gets to the box with only two little plugs do i plug anthing into them or do they just work on there own through the house electrics. (sorry but i am dame)

The router to home plug is connected via a ethernet cable

Looks like your using the wrong Net ID as some have changed recently.
If you have a VM box you pay for - press,
Settings - Technical Stuff - Network ID (top One) that your Net ID
Or
Your area provider is Telewest try these IDs
NetId - 41008 (a030) - Liverpool TDN TRIALS
NetId - 41011 (a033) - Birmingham 750
NetId - 41012 (a034) - Preston SA TRIALS
NetId - 41015 (a037) - Birmingham TDN
NetId - 41016 (a038) - Liverpool TDN
NetId - 41018 (a03a) - Preston TDN

Area provider telewest, havent got a clue where to find screen to enter Net ID - where do you and how do you enter it been through sytem time and time again cant find anywhere. (not even sure what i'm looking for)

This is a verry good link.

As stated use a VM box (if you have one) for the correct Net ID for your area.
