Macard WiFi Extenders: What to Check Before You Buy

Macard's N300 setup guide describes a plug-in extender for expanding an existing WiFi network and specifies operation on the 2.4 GHz band. Check the label and supplied documentation to confirm that your unit is this model.

The N300 guide says that model operates on 2.4 GHz, so do not assume it supports 5 GHz. Other Macard-labelled models may differ; confirm the precise model's own documentation.

The N300 guide says not to connect an Ethernet cable from the router to the extender and describes connecting a computer to the extender instead. Follow the instructions for your exact model before planning a wired setup.

The N300 guide recommends a position between the router and the weak-signal area, where the extender can still receive a good signal. If the link to the router is poor, moving the extender closer may help its connection, though coverage at the far end can change.
