Troubleshoot connection issues between Mac Studio and 2.5Gig Ethernet.
I recently acquired an M1 Max Mac Studio and purchased a 100ft Ethernet cable to connect it via Ethernet. The issue is that while it functions perfectly on my router’s 1Gb port, it fails on the 2.5Gb port, displaying only “self assigned IP.” I’ve searched for solutions without success. I’m confident the cable is suitable, but I’m unsure if the problem lies with the Mac or the router.
Which router is being used? Confirm if the 2.5G port serves as the WAN connection, as this could lead to problems.
That would be my thought too. Plus if it only has one 2.5Gbit port, unless the broadband is faster than Gigabit then there is no point in using it anyway.
There are specific scenarios where it remains relevant, such as when the Mac Studio is set to host files for other devices (each requiring 1Gbps), or if data is being collected from various LAN sources, or when port bundling is implemented. However, these chances are relatively low in this situation. The user needs to provide the router model since they suspect the 2.5Gbps port is the WAN port, which might explain the lack of IP access.
It's accurate you note this. If it's a WAN port, it could be an independent NIC built into the SoC. Bridging to the LAN via software at 2.5Gb while handling NAT seems challenging for a router SoC. I believe devices with two 2.5Gb ports are more likely to use actual switch chips. I hope they finally recognize this and add proper 2.5Gb switches to modern routers. Given the current pricing, it looks like skipping this feature isn't a good choice for these routers. From what I understand, 2.5Gb switches were priced similarly to Gigabit ones when routers first included them, though they were roughly one-third of the cost back then.
