My pc is also hardwired to my router. Although my pc does not require a wired connection to receive wifi, that is what I prefer. My router is also conveniently located just next to my pc so there isn't any issues with the (ethernet) wire going to the pc... it's such a short distance between those two devices. @Nuttmeg
Another thing about routers...
...it's a good idea to 'reset' them as much as possible. By this I mean disconnecting their power cord intermittently so as to allow for any unnecessary accumulated data to be cleared out of the router itself. Sometimes this useless data can be used by outside (hackers) to gain access into your router. Resetting the router will also allow for router updates to go into place and also improve router function, such as improved connection speed.
