Problema Wireless/Ethernet Acer Aspire 5742G (Arrandale)

1 post in this topic

Recommended Posts

Ciao a tutti e grazie anticipatamente per l'aiuto!

Finalmente (dopo ardue vie intraprese), sono riuscito ad installare Mountain Lion 10.8.2 (partendo dalla 10.8) sul mio Acer Aspire 5742G (as5742g- 488g75mnkk) modello Arrandale (Intel HD/nVidia Ge Force GT540M con memoria da 2GB, Optimus e Cuda).

Funziona quasi tutto (trovando i vari kext e modificandoli anche a volte), ma proprio non riesco a farlo connettere su internet!!!

Mi potete aiutare per le schede di rete Wireless ed Ethernet?? Sto provando 20000 kext, avrò provato a modificarne almeno 50 kext, ma il risultato che ottengo è sempre lo stesso:


- Scheda Ethernet rilevata ma constantemente "rossa" (anche settando automaticamente i parametri IP, etc etc...);

- Scheda wireless non rilevata ed eternamente disattivata, di conseguenza non fa lo scanning neanche delle reti.


Di seguito posto i dati delle mie schede ottenuti con wininfo (sono identici, sia su windows che su Mountain Lion):


- ETHERNET (pci14e4,1692): "Vendor ID: 14e4", "Vendor: Broadcom Corporation", "Device ID: 1692", "Device: NetLink BCM57780 Gigabit Ethernet PCIe"

- WIRELESS(pci14e4,4357): "Vendor ID: 14e4", "Vendor: Broadcom Corporation", "Device ID: 4357", "Device: BCM43225 802.11b/g/n"


Grazie in anticipo a tutti :)

      This is a dedicated thread about the intel 8255X based ethernet cards which, although being old (but also very cheap and easy to find used online), they still works in the latest macOS releases today i tested mine with the 64 bit compiled AppleIntel8255X kext and works like a charm! stable and withou any issues with mine 100 mbit managed ethernet switch and also without suffering of problems like connection dieing under heavy load or sleep/wake issues, so just to report that i have create this dedicated thread about and also i leave the kext as an attachment, in this post, this may be usefoul to have cheap working ethernet for hackintosh machines running the latest macOS or just to reuse old hardware some one can have laying around.

      I have started this thread to discuss about old and very cheap ethernet cards working in the latest macOS releases, cards who just uses old ethernet controllers or are new and cheap cards with old ethernet controllers, this thread is just to discuss about such cards and also to have a list in the first post with reported working cards with drivers linked.
      To contribute you have to report which card of this kind is working for you and which driver or method you followed to get it wo work and also which issues you have, and then it will be added in the list.
      I start reporting cards which worked for me, yours will be added in the future:
      intel 8255X based cards:
                just works using the AppleIntel8255X kext (look in the attachments) and seems to be stable with no issues
      And also there are some cards i am curious to see if can work with mac, so i leave this part at the end of the post, do you know if it's possible to get realtek pci (not pci express) ethernet cards working in the latest mac os? i have a few of them and i have difficulties fining drivers for mac, having a driver for the latest mac wil help me in creating also a youtube video with the cheapest hackintosh compatible ethernet cards

      I have a fully working HP-6460b with 10.13.1. For safety sake I made a clone drive for the 10.13.3. I could not update to 13.3, because it was always rebooted !!! The EFI is here: https://www.dropbox.com/s/d34g3a8uxjrb1n2/EFI_13.1.zip?dl=0 the other problem is with this EFI,  I could not update the clover, because it caused reboot requences again ! 
        So, I made a new EFI,  https://www.dropbox.com/s/viruxewplu2qbck/EFI_13-3.zip?dl=0  which was able to update to 13.3 without rebooting problem.  BUT !   In the 13.3 updated system my WIFI (BCM913224 HMS) is not working (hardware not found...) I tried to fix it dring a week but I could not fix it and not found any solution.     I think 13.3 may need a new patch for my WIFI card...  I am going to crazy, PLEASE help me if there is any solution. I think for the EFI problem there is a sure solution, so please also help me to understand which EFI should be proper for me.    Otherwise almost everything is working: audio, sleep, eSata, USB 2 (USB3 not, but I think this model can not use USB3), WEBCAM, card reader (if firewire is not allowed in BIOS) , firewire (if card reader is not allowed in BIOS) ....     Not working/not tried : WWAN (Ericson F5521) - I don't know how to install....    My detailed specification: HP-6460b / CPU: i7 2760 QM (2.4 Ghz,4/8 core,6M cache,45W) RAM 8GB, screen: 1366x768, webcam, 256 SSD + 1TB HD (in DVD slot) WIFI: BCM913224 HMS WWAN: Ericson F5521    I think many other may problem with bcm943224hms with 10.13.3 ! I can not change the WIFI card, because of this model whitelist problem !

      I am currently using El Capitan with an Asus Maximus II Formula, but the mainboard has a weird bug that the system freezes when im using the built in ethernet ports. (not only in macos, also in linux and windows)
      ... so i was using a USB Dongle wich worked fine, but the performance (USB2) was not the best.
      Now i want to add a ethernet-card to the system.
      Is there a cheap, and simple to install (maybe native?) PCIe Ethernet Networkcard that can be recommended?
      thank you

      I have an HP Elitebook 8460P running High Sierra 10.13.1
      I'm trying to get wifi working, my internal wifi as far as i can tell is not mac compatible, its a intel centrino wireless
      I also cant change my wifi card, the elitebook i have only accepts a few different cards or it wont boot past post if it is changed.
      Also i have managed to brick the system a few times attempting different kext or pkgs. I cant seem to figure it out for high sierra. 
      I have a WiFi USB RTL8188CUS, that i had working in Yosemite 10.10 using a 10.9 pkg.
      but as far as i can tell 10.11 El Capitan was the last driver support for the card, and doesnt work in 10.13.1. the wifi utility wont open to connect to a network. 
      Is there a possible way to get this card working, or do i need to buy a new wifi usb.
      If i do need a new one what would be a good one to buy? i need it to have 10.13.1 driver support and be usb also not be to expensive, N300 is good enough but i do have an AC1750 router.
      Im fairly new to getting Mac running on Intel Based PCs. 
      any help would be greatly appreciated.

      I got it working but it sometimes randomly disconnects me from wifi and wont reconnect until a reboot.
      The kext i used was for 10.11 El Capitan. i was just using the El Capitan only kext before and not the multi edition kext.
      Attached is the utility and kext i used.
      So i still need help but i have made a little progress
