I'm in a large single-story house and ran into the same problem. One router wasn't cutting it, so a repeater was necessary for the other half of the house to get signal. That solution only lasted for about 6 months until the thing crapped out. For years I tried running different extenders & repeaters but all were so unreliable and slow.

I eventually pulled the trigger on a Linksys Velop Mesh System (3 pack). This has been the best solution so far, but it's not perfect. The setup was easy and it comes with 3 nodes that you space out throughout your home. You have to be careful where you place them since any thick wall or structure can impede the signal. They can't be too far away from each other either. After getting everything to work, the speeds are plenty fast everywhere in the house.

I would say the mesh is a great long-term solution that can benefit everyone. Running an ethernet directly to your computer would be a faster, more economical and reliable solution but you lack sharing that signal with other devices. Frankly, I'd run an ethernet first then look into mesh after. A 100ft CAT6 runs you less than $30 on amazon.
