oh I absolutely do and this is the last lesson I am going to give you in rudimentary networking and then you can go off and read some links

well that's funny because in previous posts you said it was connected by wifi but I will agree that it has a wired connection. The wired/Ethernet connection is not exclusively for internet access as you maintain. As I have stated previously, Ethernet/wired and wifi/wireless are just different ways devices can connect to a router. The router creates and maintains a network and if the router happens to have access to a gateway (internet access) then it can forward the traffic. The Ethernet connection your pc has to the router is to provide the pc network access whether it be to a networked printer or access to the internet.

no it doesn't, it means the wireless adaptor on the pc (wifi) has no network connection which means it is not connected to the router and has no access to networked services including the internet. The PC is connected to the internet because it has a wired network connection which is up.

NO NO NO! Ethernet is a communication standard for WIRED cable connections and has nothing to do with wireless communication. You have two completely separate network adapters in your pc, one for wired and one for wireless. As I stated in previous posts, your wired connection takes precedence over wireless so your network connection is active on the Ethernet network adaptor connecting you to the router which is labelled as "virginmedia bla bla". If the router happens to provide access to the internet as well as other networked services (e.g. printing) then great. Your pc is not using any wireless connection and it is in no way whatsoever connected to your printer wirelessly. The list of wireless networks in your screen dump is not a list of connected networks, it is a list of networks which the wireless adaptor says are in range and can try and connect to. You are not connected to any of them until you click on one of them and then enter the necessary credentials such as network password. You have not done this which is why your network adaptor says it is not connected. The network names look similar because it is broadcasting the network name of the shub but note that the wireless network has a 2 at the end to indicate that it is the second network to have this name, the wired one being the first. You can easily avoid this confusion by logging into the shub and giving the shub one name and the wireless ssid (wireless network name) something completely different like Christmas. That way you will always be crystal clear which one you are connected to and also avoid connectivity issues in the future in case you try and connect to a neighbours router which is also called "virginmedia bla bla".

because they are the same thing and it is not connected. The wireless network adaptor is not connected to a network thus your pc is not using wifi. You have a wired Ethernet connection which is up and has nothing whatsoever to do with wireless.

no it is not, the printer is not connected to the pc at all and is not using an Ethernet cable. The printer is a networked device and maintains its connection to the network via a wireless connection/wifi to the router. As stated previously, the printer does not care what is beyond the router or what other devices are connected to the router. Any device such as your pc which needs to communicate with the printer does so by sending the information to the router and router sends it on from there. It doesn't matter which device is Ethernet or wireless as long as they can connect to the router. The router manages the individual connections and makes sure each of the devices can communicate with one another.

no you do not, as I have just said above, each device only has to worry about how it is going to communicate and maintain its own connection to the router. It is the routers job to manage the collective connections/network and make sure everything can talk to each other. A wired pc can print something on a wireless printer and a wifi connected tablet can print something on an Ethernet/wired connected printer. They are different types of connections which the router has to manage and allow all the networked devices talk to each other. That is what routers are for. If your want to print something on your pc your pc will send the request through it's Ethernet connection to the router, the router will then see where it needs to go to, see that the requested device is connected wirelessly and send the request over wifi. The printer does not know that the originating device (your pc) has a wired connection nor does it care.
To save your brain exploding I want you to think of this scenario. You work at the Foreign Office and your job is to service diplomatic requests from around the world. Everyday you come to work and your secretary has a pile of requests ready for you on your desk which she has typed up and are all in English in the same standardised report format which you are used to. What you don't know is that Chin Wan in China hand wrote his request in Chinese and it had to be translated, Gunter in Sweden emailed his request, Hans in the north pole sent his via morse code and that Beatrice sent hers through the post in Braille. You are completely oblivious and do not need to know. Each person had their own way of getting the information to the secretary, the secretary put it into a format which you could understand and respond to, you are going to process the request, give it back to your secretary and she is then going to make sure it gets back to the relevant person in the same way they sent it to her.
