So I have all of my laptops upstairs, along with almost everything using a wireless connection. My downstairs only has the apple TV. My cable connection comes into the house downstairs, near my bookshelf. So I have the cable modem plugged into the 5th gen airport extreme. I then extended the wireless signal using the AC airport extreme upstairs. For the most part it works fine, but there are times where the connection lags just a tiny bit, with dropped packets too between the routers. For example during a voip call, the other person would start talking and I only catch the tail end of their sentence. And then as long as that conversation continues, all is fine Jabber / IM conversations too. Most of the time, sentences will be posted right away, sometimes there will be lag. I open a traceroute and there are timeouts between the routers when this happens. So would buying another AC airport extreme and connect it downstairs help with this? Or do i really need to start drilling holes and wiring all this?
