Chinese SSID With function of build in firewall, IP filter, URL filter and MAC filter With.Hopefully, you’ll never have to use either the normal or internet Recovery Mode for your Mac, but if you do it’s simple to access. No big surprise cause it looks like they are using same Ethernet chipset like Belkin anyway with Product ID: 0x8153 and Vendor ID: 0x0bda (Realtek Semiconductor Corp.)Features wifi as wan or ethernet connections to the Internet. I tried also another USB-C Hub with Ethernet port by Epico but also with no success. Internet Recovery ⌘+⌥+R starts with spinning globe, but it takes for ever, drops down with errors, etc. New Internet Recovery Feature: The new internet recovery feature will cache the recovery image so Mac computers can be restored on your network quickly.I can confirm probably exactly the same issue on my new MacBookPro14,3 with Belkin USB-C Gigabit Ethernet Adapter. Now, there are over two dozen data types supported, including apps, books, iCloud content, GarageBand music, software updates, Xcode components, internet recovery, and plenty more.
![]() Using Etherneton For Internet Recovery Mac Computers Can![]() It seems like Realtek ethernet chipset is the thing which is causing the problems.I think that Apple should take care of this it self and at least provide it's own USB-C to Ethernet Adapter which works properly, when they left us just with 4 USB-C ports and nothing else on these days MacBooks. Internet Recovery boots fast and installation is stable.On the other hand it's pretty weird that Apple sells something officially on Apple Store (I'm talking about Belkin USB-C to Gigabit Ethernet Adapter) which doesn't really work for Apple's Key Services what Internet Recovery certainly is!Thunderbolt to Gigabit Ethernet Adapter by Apple have Vendor Name: Apple Inc., Vendor ID: 0x1 and Product ID: 0x8003 instead of Realtek Semiconductor used in Belkin's Adapter which probably makes difference. Here's a paste from the original post to give proper credit:"Thunderbolt 3 (USB-C) to Thunderbolt 2 + Thunderbolt to Gigabit Ethernet Adapters(Both made by Apple)With this combination of connecting Ethernet over two adapters to one of your USB-C port everything works like charm. Install mac os emulator onlineCompany Wifi and other adaptors failed to even load Recovery, leaving me with error code 2003F and 3001F. Oddly enough, the only way I could get to Recovery was to use the Belkin adaptor. I don't have the Thunderbolt 2/Ethernet Apple adaptor.For me, Wifi and three ethernet adaptors failed to re-install macOS in Recovery. I wanted to share my experience in case it helps someone.I tried Wifi and three different ethernet adaptors: Belkin F2CU040, Cisco LINKSYS, and Apple USB Ethernet on a MacBook Pro 15-inch, 2018. Chains is not really a fancy solution.What a mess. The logs show that the Mac reached Apple Servers and the packages (6GB+) were downloading. Still, macOS reinstall got stuck at minute 3 or minute 2. I saw that the other adaptors wouldn't get an IP and the Terminal DHCP commands worked for all adaptors. ![]() I clicked on it and rebooted.After all those steps, it booted and I have a working Mac again. That Mac looped for a bit, but finally it asked to restart because the system needed an update. Hoping to get back into Recovery, I plugged in the Belkin adaptor. At first, the MacBook looked like it was booting into Recovery Mode again, so I thought it didn't take. Video to image converter for macEventually the traffic slows down to a point where nothing is transmitted for several minutes. Black lines everywhere in the Wireshark console. Retries, retransmits, dupes, etc. I've been able to repeat this over and over again.The problem is as bad as everyone says: when you use third-party gigabit-class USB-C Ethernet adapters (Belkin, Dell, etc.) they all exhibit an absurdly high amount of dropped packets. I used Internet Sharing (Wi-Fi > Ethernet) and Wireshark on another Mac to monitor Internet Recovery's loading performance with several different adapter combos. I kindy responded that I purchased this adaptor from Apple.Adding to the pile. It's likely that Apple didn't bother with this because HW/SWE prioritized Wi-Fi performance over Ethernet. Space is a valuable commodity in firmware, so all code has to be hyper-optimized and compact. USB has no controller and has always offloaded the processing to the CPU, which requires more robust drivers. Something happens under high speed loads with USB-C that causes the code to freak out, crash a buffer, and stop transmitting.Thunderbolt has a dedicated controller and is unaffected by these issues. When you use Thunderbolt, it's fast as lightning (no pun intended).I'm not an expert at Ethernet protocols or low-level drivers, but If I had to take a guess, Apple's firmware code probably includes only basic USB driver support and was never fully tested with the gigabit-class USB devices, only with Apple's 100Mbit USB adapter.
