Sinds een paar dagen heeft wifi kuren.

Welke OS X versie? Welke MacBook Pro? Wat zegt Etrecheck over je Mac?

Macbook Pro 15" retina  2GHz eind 2013.
OSX 10.10.5  maar het probleem was er ook al in 10.10.4
Als wifi géén verbinding met een netwerk maakt blijft het icoon lichtgrijs, maar
zodra er verbinding gemaakt wordt met een netwerk gaat de wifi uit.

Onder /System/Library/Extensions staat een hoop oude rommel (die overigens niet geladen is en dus niet direct kwaad kan doen, maar misschien draai je oude apps die niet verder kunnen zonder deze extensies). Twee keer Flash. DivX heb je niet nodig. Wat is Novatel/Movamedia? Misschien toch maar 's MalwareBytes draaien.

Je Etrecheck rapport is afgekapt.

Je SSD zit te vol.

Tip om lang zoeken te vermijden:
- Backup maken
- OS X 10.10.5 schoon installeren
- Laatste versie van noodzakelijke apps/extensies herinstalleren (van website leverancier)
- Data terughalen van backup

+1, maar al de ouwe troep komt wellicht al van een backup. Dit leest als typische Migratieassistent sores. Clean install, en handmatig migreren lijkt aangewezen- hoewel ik huiver bij die gedachte. Wat een job!

Henk

Hoeveel buurnetwerken zitten er op hetzelfde kanaal als jouw netwerk volgens iStumbler? Wijk eens uit naar een ver afliggend kanaal met je thuisnetwerk/router. Desnoods naar de 5 GHz band zonder meer. De 2,4 GHz band zit tegenwoordig gewoonweg te vol, vooral in conurbaties zoals de Benelux/ Brussel tot A'dam.
Nog een experiment: zet je Bluetooth eens af. Werkt het dan? Recent een Bluetooth apparaat bij in je keten opgenomen? BT interfereert namelijk geen eind met WiFi op de 2,4 GHz band. Courtesy of een gedeelde Broadcom WiFi/ BT chip in de Mac. Ik dacht dat 10.10.5 daar een oplossing had voor moeten brengen...

Op 5GHz en 2,4 maakt hij verbinding en na een paar seconden schakelt wifi uit.
Die novatel/media is gebruikt om met genymotion een smartfoon te simuleren.
Nu die fysiek aanwezig is kan dat verwijderd worden.

Zit waarschijnlijk in de software,
nieuwe gebruiker geeft zelfde probleem, maar als gastgebruiker
( met alleen safari als programma mogelijk)  blijft wifi het doen.

Dat is wel een indicatie: geen probleem met een gast-account waar alleen Safari is toegelaten.

Je kunt aan twee kanten beginnen:

1. Je systeem schoonmaken (met name de dingen verwijderen die in het Etrecheck rapport [failed] vermelden).

2. In het gast-account één voor één andere apps toelaten en kijken of wifi dan weer plat gaat. Die app (of extensie of plug-in) zou dan de oorzaak kunnen zijn.

PS. Tips uit m'n eerdere bijdrage lijken nog niet vervolgd. Hoeft ook niet maar een oplossing kan dan misschien lang duren. Als je meer verduidelijkt wilt hebben, laat het dan hier weten.

Zeer goeie raad, jtk.
Wat ik persoonljik foute boel vind, zijn al die Novatel componenten (Huawei/ Samsung drivers etc.), maar ook de "connectservice" app: http://apple.stackexchange.com/questions/42519/what-is-connectservice-app
De Etrecheck zit sowieso vol onnodige troep. Man, man dat gaat een job worden om allemaal netjes te verwijderen zonder clean install...

Vandaag bij m'n schoonvader geweest z'n iPad was vergrendeld en hij was de code vergeten.
Was m'n apple-id ww vergeten en nieuwe aangemaakt toen deed ook de wi-fi het weer......
En de iPad ff later ook natuurlijk.
Dat je wi-fi van je apple-account afhankelijk is.

Ik denk dat je blijheid tijdelijk is!

Ja, via iCloud worden wifi netwerken en wachtwoorden gesynchroniseerd. Maar de juiste werking van wifi hangt er niet van af. En mochten de iCloud settings in de weg zitten, bijvoorbeeld omdat het netwerk een ander wachtwoord heeft gekregen en/of een andere update heeft gekregen, dan kun je dat netwerk simpelweg vergeten en log je opnieuw in.

En wellicht ten overvloede: je Apple ID is niet iets om te vergeten! Onthoud deze goed, je persoonlijke data (bv online back-ups) en vele andere zaken (bv iTunes tegoeden) hangen er van af!

Ik heb geen iTunes tegoeden en geen iCloud backup dus daarvoor hoef ik het niet te doen.

Wat bij mij ook nog wel eens wil helpen is de router van m'n provider (UPC/Ziggo) herstarten.

Find my iPhone locaties, photo stream, sleutelhanger wachtwoorden, ...

Onthoud: je Apple ID is belangrijk!
