I have a Vodafone complete modem router (Wifi disabled), an Airport Extreme, and an airport express at the other end of the house. This is set to extend the network, however I haven't had it plugged in for the last week while I trouble shoot the issue. I've also tried a newer modem router supplied by vodafone but still have the same issue.
I've also tried unplugging the airport extreme and just using the wifi on both Vodafone routers, all with the same result.
I'm wondering if the problem may be with a setting on the macbook pro itself? I've tried 2.4 and the usual 5ghz network that it runs on.
I get regular ping tests of 501ms or higher from ping test on a local server.
Its getting super frustrating waiting for the internet to respond. We have a master filter which the modem is connected to. Is there a way if I can determine what the fault is?
