Cables really aren't hard to run Hit. You can buy a gang n port with wall plate that dresses out nicely. In most cases you can run the patch cable in the crawl/basement or attic. Finding the sill plates to drill the passage hole is not as hard as people think. A few cable clips to hold the patch in place and it's done. One central wifi is usually inadequate for a two story house.That's a good point Bronze. Cables are not hard to run. I ran cables to my TV and Apple TV box. I didn't want to have to worry about buffering on wifi. I wonder if I could add a five port ethernet switch and then run a bridge from that. She's not home from college much but my youngest complained before about wifi signal strength on the second floor of our house.
I see no reason why you cannot add a five port switch and run a bridge from that. My router has four ports so I don't need a switch. However, I am adding a second access point plus I use the other two for other stuff and I will be maxed out on ports. Any more and I'll need a switch.
I actually use one repeater for one purpose. My kitchen TV. The TV is in such a place where wifi signals go to die. Don't know why. So I have a repeater behind the TV (for my roku) and the signal is off the charts for that one TV. I'm adding another access point in the LR so I'll see if that works for the kitchen TV.
