Explore the guide library · Extender and mesh comparisons
A 100 Mbps port and a 2.5 Gigabit port create very different wired-path limits, regardless of the wireless label.
When an extender will use Ethernet, its port specification deserves as much attention as its wireless class. The cited RE315 revision 1 page lists a 10/100 Mbps port, while the RE235BE EU revision 1 datasheet lists a 2.5 Gigabit Ethernet port.
Identify the proposed role
In access-point mode, a wired link feeds the wireless network. In extender mode, the port may connect a nearby wired device while the upstream link remains wireless. Confirm the exact model’s supported modes before assuming either arrangement.
Translate the port difference into a requirement
If the intended wired path needs more than 100 Mbps, the cited RE315 port cannot provide that link rate. A faster port removes that particular limit only when the connected router, switch and cable also support the desired rate.
Do not replace an adequate device automatically
A modest application may work satisfactorily through a slower interface. Define the failure or missing capability first. Replacing hardware solely because a number is smaller can cost money without improving the service the household notices.

| Which regional revision is sold? | Specifications and firmware can differ |
| Which mesh system is required? | A matching brand is not enough |
| Which client needs improvement? | Client capability affects the benefit |
Verify the installed path
After setup, inspect Ethernet negotiation and test an actual local transfer or internet workload. A wireless connection displaying a high rate cannot override a slower upstream Ethernet port.
This comparison does not establish measured coverage or throughput for either product. It identifies a concrete specification that can decide a wired installation. Choose according to the required mode, supported security and complete network path, then validate the result where the device will actually operate.
