Having read many posts from others having the same problem, I was inclined to think it was a problem with the TS4.
It’s hard in these circumstances to know whether the problem is with Apple or the third party vendor. I appreciate your joining just to let me/us know I hope you will enjoy our forum enough to stay! I have known of CalDigit as a high quality hardware vendor in the past, so I am disappointed that they seem to have a hardware issue and are not more proactive in acknowledging Thank you for bringing us this information. If I decide to go ahead and add the second ASD, then I will need the TS4 to be able to maintain single-cable connectivity to my MBPro (assuming this actually works when I get the monitor), so at least for now I will stick with the TS4.ĭisappointing. I have a second ASD on order, with a ship date in June. Right now I have an Apple Studio Display connected via TB and an LG 4K display connected via DisplayPort. I hated to “waste” a USB-C port but there it is.Īs far as I am aware, there are no other docks available that can (or at least claim to) support dual 5K or greater resolution monitors. As such, I don’t plan to return it at this point, as I doubt a replacement will fix the issue.įor now I have hooked up a UBS-C to ethernet adapter and my wired ethernet works fine. I suspect they are correct that another TS4 is unlikely to fix the problem, but I believe the reason is because of a hardware flaw in the TS4, not because mine specifically is defective.
However, if you are able to confirm that this feature has been disabled, or that your TS4 encounters the same issues when connected to another Thunderbolt enabled host that does not have this feature, then I would be happy to proceed with an RMA under warranty given the following information:”Īt this point, I’m not quite certain how I want to proceed.
EEE settings are a potential culprit even with a full and proper connection to your switch. I’m afraid that without verifying that the Energy Efficient Ethernet settings on your computer have been disabled, we cannot be certain that a replacement TS4 dock would not see similar issues emerge. I was finally able to get it done, but nothing has been fixed. I have also tried removing the hardware profile as directed in network preferences and recreating it with energy efficient disabled, but that provided quite difficult to do as you cannot create the interface when there is no hardware connection. I replied that I did not think that was the issue given that the hardware is clearly not making a connection. The email response directed me to the two support articles that have already been linked in this thread. I requested a warranty replacement and asked for a cross-ship as the TS4 is now central to my connectivity. In my mind, that points to the TS4 hardware. I noted this to be the case with three different ethernet cables connected to multiple ports on the switch and to multiple ports on a second switch, and that all three ethernet cables make a connection (lights lit both ends) when used to connect the two switches. I delineated the issue I have with the ethernet connection, noting that when I connect the TS4 via ethernet to my switch, I get no lights on either the switch or the TS4 to indicate there is a hardware connection. I opted to send an email to support instead. When you call their telephone support line, you get a recorded message basically telling you that no one is home, and instructing you to leave a message and they will call back. I can use a USB-C to Ethernet adapter as a workaround, but still very very frustrating.
I am suspecting CalDigit from what I have read online (there have been reports of issues with intel Macs as well, so I don’t know that it is due to Apple silicon. This is frustrating that either CalDigit or ?Apple don’t have this right. WiFi, if I just disconnect Ethernet, works fine. I tried rebooting, disconnecting and reconnecting the TB cable and the Ethernet cable, power cycling the TS4, with no luck. After reboot, I find that the Ethernet will connect for a few seconds, and then lose the connection. In any case, up to now my Ethernet connection has been working just fine. I have a second Studio Display on order although I may cancel and stick with the 4K. Part of my reason for buying the TS4 is that it is, as far as I can tell, the only dock that supports two 5K displays through a single TB cable. I was particularly happy after getting my new Studio Display, as my prior LG 34” 5K monitor would take a long time (think sometimes several minutes) to wake from sleep, while the Studio Display was waking up instantly, as was my second display, a 27” LG 4K. I was running MacOS 12.2, and experiencing no issues at all. I have a CalDigit TS4 dock connected to a 14” MBPro M1 Max.
There have been postings here and elsewhere on the difficulties with wired Ethernet connections using CalDigit TB docks.
