How do I identify the correct adapter in ipconfig?

The output of ipconfig can contain several adapters, even on a laptop with one visible network connection. Find the section for the interface you are actually using before interpreting an address or default gateway. Decide whether the test uses Wi-Fi, built-in Ethernet or a USB dock. Note whether an approved VPN is active. A virtual adapter can be relevant to the application without being the physical link to the home router.

What should I compare on UE302C and USBC-E2500 adapters?

TP-Link's UE302C and Plugable's USBC-E2500 both provide a 2.5 Gigabit Ethernet interface for a compatible computer. The useful difference is how each fits your laptop and support requirements. Neither product makes a gigabit router port operate at 2.5 Gbps. Plugable's connector flexibility can be useful when moving between older desktops and newer laptops. A dedicated Type-C adapter can be simpler if all intended computers already have an appropriate free port. Confirm the exact regional package rather than relying on a marketplace photograph.

How do I fairly compare phone and laptop Wi-Fi speeds?

A phone outperforming a laptop on the same Wi-Fi does not prove that the laptop is broken. Different radios, antennas, supported bands and software can produce different results. Start by making the test conditions comparable. Place the devices near the same position and test them one after the other, not simultaneously. Keep the laptop lid in its usual working position. A phone beside the router and a laptop behind a metal desk are not measuring the same wireless conditions.

Why might a mapped drive disappear in an administrator application?

A mapped network drive may open normally in File Explorer yet be unavailable inside an application launched as administrator. That pattern can concern Windows' user context rather than the physical network. Rebooting the router is unlikely to explain why one process sees a drive letter and another does not. Open the same mapped drive in ordinary Explorer and note the result. Then record the application's exact error and whether it is elevated. Do not change the NAS or credentials while the basic comparison is still unclear.
