The best option would be to actually run an ethernet wire from where the router is to where the computer is. The hard way of doing this is to run the ethernet cable through walls or under floors or in ceiling. For many, this is not practical or possible. You could pay someone to do this for you, assuming there is no issue with drilling holes, etc in walls, ceilings, and/or floors (might not be allow if a rental). The easier way would be to run the ethernet cable exposed, but then you would have this ugly cable running somewhere visible. This is more practical to do, but may not be desirable for many people. Overall, running an ethernet cable will give you the most reliable connection. How viable this might be can also be "adjusted" by maybe also adjusting the local of the router potentially, but only you really know the layout of your home and where the places the router can realistically be put.
From there, the options are pure wireless for your computer, using a wireless bridge like you are currently doing, or using a set of Powerline adapters.
For Powerline adapters, they can work well or not. Best you can do it try. The key is that the two Powerline adapters need to be operating off circuits that go to the same master breaker/fuse box. They don't need to be on the same circuit.
As for either a pure wireless option or your wireless bridge option, there might be ways to improve what you currently have. To explore that, you would at least need to be more specific as to what you current setup is. What is the make/model of your current router? What the make/model of the "repeater" that you are using? Have you tried a pure WiFi connection on the desktop?
You mentioned that moving the router closer to your computer (i.e. in your room), but that your family uses the Internet. How does your family connect to the Internet? Is it by WiFi? If they only use WiFi, then moving the router would seem like the best option. If that results in weaker connections by WiFi, then that might be able to be addressed. Obviously, if other family members connect by ethernet, then you are effectively just moving the problem. As to you hating leaving things turned on in your room while you are away, if moving the router into your room is the best option, then you might just have to get over that and/or be willing to leave the room unlocked if you are worried about the router overheating or catching fire or some such...or live with a less optimal solution assuming there is no other way to run an ethernet cable to the computer from the router's current location.
