It is possible that for some operating systems that the case is sensitive for both username and password or router name and password. It is also possible you have reached a certain limit of the router in terms of wireless connections. There are many things that can cause wireless to fail*:

Also some routers need a firmware update to be compatible with some operating systems. Better to do a direct ethernet connection to the router, and try it that way.
If you were attempting to upgrade to Mac OS X 10.11, note many printers and scanners no longer work. See my user tip:
El Capitan System (10.11) requirements for upgrade - with important note about Sierra

Mar 11, 2016 9:50 AMby Rosejo,Thanks, i have a really bad story concerning computer modifications behind me, and i dont want to go with it any more.
I'm very careful about testing and configuring. So this is a minimalistic Szenario. One mac, fresh pasword for WLAN and one single box to the Internet, no additional Clients allowed ...
My mac do not have any problems, when i boot normally.

Mar 11, 2016 9:44 PMby Rosejo,I use the OSX 10.8.5 Base Partition for the Boot, so nothing additional would be the right answer, i think.
About 10 GB free harddisk space, but this should be more than enough for that small recovery system.
But i have some strange effects here too.
You could See one in the picture i did in my tread about a possibly virus on this mac.
The others are eg. longer boot time even for the recovery boot and when i switch oft the wireless LAN Adapter after some minutes it is back on automatical.
Sounds strange is strange.
It did that after burning a CD and reinserting it unter the recovery system.
So i guess i need forensic help and a 100% clean install. Do you know anyone.
Is there a possibility for a verification of the MB, eg. firmware of the motherboard or/and wireless lan adapter? (Should be a New question)

Apple Hardware Test doesn't catch everything, so even if it doesn't find a problem, you could have one.
