I have a router connected to a modem. My intention is to connect to this router from an office that's about 200 feet away and through 2 walls.
The router signal is not strong enough to get to the remote location, so I have put a range extender in between.
The thing that's extremely confusing is that when my computer (or any client) connects to the extender while sitting right next to it, it works perfectly (ping times of about 30ms).
However, when I move to the remote location, even though the wifi signal strength is either 3/4 or 4/4 bars, the packet loss is massive, and the latency varies wildly where for a stretch it will report pings of about 50ms, but then will drop to 800+ and about 10% are just timed out packets altogether.
So, my question is... if the signal strength is good, why would this distance create such horrible packet loss? And what could cause such interference? I'm in a residential neighborhood, but there is absolutely nothing, line-of-sight between the laptop and the signal repeater other than 2 walls (with whatever electrical wiring is in them).
