we're at a buddy's house and unable to log into his wifi network. both mbp-rs are 2012 or later.

one of the machines consistently gives a message, "The Wi-Fi network '***' could not be joined. Try moving closer to the wireless router. Alternatively, run Wireless Diagnostics to troubleshoot." This is a school machine for which only network administrators have the credentials, so running wireless diagnostics is not an option.

the other machine consistently gives a connection timeout message. network diagnostics does not produce helpful results on this machine, although it does create a file of diagnostic reports that i don't know how to read nor for what i should be looking.

both laptops have been placed within a foot or so of the wireless router with no different results. both machines were working fine previous to attempting to connect to this network.

an iphone 6 was able to join the same network with no problems.

i'll appreciate any assistance.

worst case scenario: we still get to see the who tomorrow night!

note: on the machine giving the "network could not be joined" message, the wifi icon in the menu bar with the concentric arcs shows the arcs as active (inside to outside). on the other machine that icon is totally inactive.

Reboot.

Saint Cloud, Minnesota, where the weather is wonderful even when it isn't.

As Speedy said, or try turning AirPort off for a minute or so and then turn back on. But a reboot is more likely to help.

Be seeing you.

Have you clicked "Advanced" (System Preferences>Network>Highlight the Airport network you want, then click Advanced)? The OS will then try to adjust the settings. Usually works for me. I'd also check the DNS settings.
