I'm not a Mac guy, but I can service them to a point - premise set!
A client has a WiFi network through a local ISPs router (OPTUS) using a Netgear cable modem/ router.
They are a Mac houshold, with a Mac Desktop & a number of iPads (1 or 2) & Macbook Pros (3, that I configured).
Of these devices, all connect wirelessly... all except one of the Macbook Pros.
The Macbook Pro in question is a Core i5 running OSX 10.7.5 and seems, in all cases, to be a pretty good machine.
But here's the conundrum...
When I attempt to connect it to the local router, I get a time-out error. However, when I was there and connected it to the WiFi Hotspot on my Samsung Galaxy S4 (Android), it connected without a hitch.
Is it possible that the modem/ router has a limit to the number of devices (or specifically, Macs - why would this make a difference?!) which are able to connect to it simultaneously? This was the only thought I had because the router appears to be working fine, as does the Macbook Pro... and yet, nothing!
One other Macbook Pro which I was next to at the time I checked the OSX version of the Macbook Pro in questions was 10.4.x, so a bit older but still able to connect and browse.
Would love to hear your thoughts on this!
