Question

Can I make the router use an older WLAN protocol (WEP) with Lion?

A Collegue to which I am to help got a new Router, which wwas pre-configured by the provider.  

The Lions (Montain-Lions) on MacBook Air can connect to Internet easily across of my iOS 9 mobil (personnal hot-spot).

My iOS 9 devices connected immediately. Though older OSX (Lion? ML?, I do not know for sure at the moment) does not.

They see the net in airport and can fill in the PW and the ’antennas’ in the menu is showing good connection, though Mail and Safari (the only available applications) are reporting: no connection to Internet.  

Maybe the the kind of connection is newer than the older systems can do per se.

That will not change anything, except make your network less secure. The encryption method does not affect the rest of the internet connections, and you indicate that you are connecting to the WiFi.

You might want to check if you have a valid DNS address

System Preferences -> Network -> Advanced -> DNS

You can test your own DNS addresses by clicking on the [+] and adding something like

OpenDNS.org

208.67.222.222

208.67.220.220

Google DNS

8.8.8.8

8.8.4.4

You could try running "Network Diagnostics"

Finder -> Go -> Go to Folder -> /System/Library/CoreServices

This should open a folder

Double Click on -> Network Diagnostics

follow the instructions.

Thank you, Bob Harris.

Networkdiagnostics reports OK; I restarted the modem (in line before router), then toke a call to the provider, after the call, doing nothing, all was ok; I think to restart the modem did the work. On the other hand never I had the case networkdiagnostics helped anything. specialists may read protocols, I believe on it.
