Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: Archer AX73
What that covers: TP-Link router/Deco; EasyMesh/Deco controller, Wi-Fi generation, HomeShield and Ethernet ports vary.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Wi-Fi 6 router (single unit, dual-band): A Wi-Fi 6 (AX) router with 2.4/5 GHz (no 6 GHz — that is 6E/7). Wi-Fi 6 speeds need Wi-Fi 6 clients; older devices connect at their generation.
Single router coverage: Limited area as a single unit; add OneMesh/Deco or place centrally for large homes. A weak room is coverage, not a fault.
Managed by Tether app or web: TP-Link Tether app or web admin. No 6 GHz band (generation limit).

Exact questions

Questions that only have an answer for the TP-Link Archer AX73 router

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

Does my TP-Link Archer AX73 support 6 GHz Wi-Fi?+

No — the AX73 is a Wi-Fi 6 (AX) router with 2.4 and 5 GHz bands only. The 6 GHz band arrived with Wi-Fi 6E (the AXE models) and Wi-Fi 7. So there is no 6 GHz network to find on it, which is its generation rather than a fault. It still gives strong Wi-Fi 6 performance to compatible devices on 5 GHz.

Structured depth, not empty permutations

Every published record carries a direct answer, scope, ordered fixes, risk notes and sources.

Device and manufacturer hubs share a consistent record system, but each answer carries the relevant controls, fault boundaries, consequences and official support entry point for that platform.
