I am not so technical so please humor me.
I am well aware and have used tethering of my (Android) phone to my PC by USB and understand it can also be done with the phone as a wireless hotspot or bluetooth.
But I am curious is if there are specific routers available (maybe with a USB port, maybe not) where I could toggle to a router instead so that I could use the LAN ports on that router.
I have done some searching and have found that there is such a thing as routers with USB ports (but never mention of plugging in your phone) and also perhaps better a device called a BRIDGE (not sure how it connects to the router) which might be a way to send the phone's net connection to the router.
If this is possible, I think specific devices and likely custom setups would be necessary.
So to the tech geeks here, what do you think about this? Possible, not possible, if possible. how exactly?
