My father's laptop can't connect to the network printer through WIFI. We were able to narrow the problem. Three MiniPort WAN are dysfunctionnals and are displayed with a warning by Windows.
In ordre to solve this issue I need to be able to uninstall these drivers. There are some explanations available, but they do not work with Windows 8. In order to re install theses drivers, they must disapear from the device manager.
Here is the problematic part, I can't achieve it. See , deleting the register break down the wifi. I do not have errors when I uninstall these drivers, but they do not disapear from the device manager.
Another link, explains that we must uninstall TCP/IP, before deleting the register key. But you can't uninstall TCP/IP on windows 8 because it is a core component. You can reset the driver easily still.
The only known way (at least to me) to uninstall these drivers is to delete them in Windows/inf, and in system32 (not sure for this one). The author explained that it made the drivers disapear from the device manager, but windows became soon quite unstable.
So do you have any ideas ?
Edit : I'm a software engineer, so I can handle technical explanations.
When we connect two computers to each other using a medium and no other computer is connected to them, would we call this network a PAN or a LAN? We usually connect peripheral devices in the case of PAN. What about this case?
PAN and LAN (and WAN) are subjective terms, but the distinction I would make would be:
If you have the two computers plugged directly into each other, I would agree with Tog that they are simply linked together. You can say they are networked, but in my opinion it's a little misleading.
If the two computers plug into a switch or hub, then I would say you have a LAN which happens to only have two computers on it.
Two computers plugged into each other is still a network, even if there is no router or switch, they still communicate as any device on any network would, its just a different organization.
WAN is of course wide area, so it involves linking many networks together over a wide geographical area, where each segment is separate not just by organization, but actual geographical distance (separate buildings, separate states, separate countries).
LAN typically refers to computers networked at a single geographical location, and this is usually a setup for an office or home in which different users will use computers on the network, whether the same machines or different ones.
PAN would be a network that all devices are used only by a single user, which is most commonly a bluetooth link, but is the same as a single person having 3 computers on a home network for which only he/she will ever use.
