No, a properly functioning PoE (Power over Ethernet) injector does not affect network speed
.
PoE injectors are designed to deliver power to devices over the existing Ethernet cable without interfering with data transmission.
They simply add power to the network connection without altering the speed of the data transfer.
Here's why:
-
Data and Power on Different Pairs:PoE injectors use specific pairs of wires within the Ethernet cable to transmit power, while the other pairs carry data.
-
No Signal Interference:The power is injected in a way that doesn't interfere with the data signals, ensuring data transmission remains unaffected.
-
Speed Matching:A PoE injector should be chosen that matches the speed of your network (e.g., Gigabit PoE for a Gigabit network) to avoid any bottlenecks.
-
Cable Quality Matters:While PoE itself doesn't slow down the network, poor quality or damaged cables can increase resistance and potentially affect speeds, but this is not a PoE-specific issue.
Therefore, if you're experiencing slow network speeds after adding a PoE injector, the issue likely lies elsewhere in your network setup, such as the cable quality, the device's network card, or the network configuration.

I'm not convinced, this is an ordinary POE injector that has
no effect of signal speed
. It just ads power to a single pair that is not otherwise used.

How do I know if my PoE injector is bad?
If the PC's Network Interface Card stays "identifying" instead of "Unidentifed"
this may point back to the D-Link as the issue even if it's network connection shows "Unidentified". If the 'Local Area Connection' says "Network Cable Unplugged", the PoE is bad and needs to be replaced.

Can you use a PoE injector with a router?
late reply, but yes -
plugging the SL router into your POE injector works fine
(router > poe injector > dish on extended/repowered cable line). the POE output on the dish ``searches'' for a compliant device, vs how we're just supplying all the time.
