TP-Link Archer AX55: specs and speed limits
The Archer AX55 is TP-Link's AX3000 dual-band Wi-Fi 6 router. Sources: TP-Link's product page and the FCC filings (FCC IDs 2AXJ4AX55V4, 2AXJ4AX55, 2AXJ4AX55V2, 2BCGWAX55).
Specs
| Spec | Value | Source |
|---|---|---|
| Wi-Fi class | AX3000 | TP-Link |
| Wi-Fi standard | Wi-Fi 6 (computed: 802.11ax is the highest mode in the maker's speed line) | TP-Link |
| Bands | 2.4 GHz and 5 GHz; no 6 GHz | TP-Link; FCC grant |
| 5 GHz max rate (maker) | 2402 Mbps (802.11ax, HE160) | TP-Link |
| 2.4 GHz max rate (maker) | 574 Mbps (802.11ax) | TP-Link |
| Total spatial streams | 4 (maker does not split by band) | TP-Link |
| 2.4 GHz streams | 2 — calculated from the maker's per-band rates, not a maker statement (see Stream-count math) | TP-Link |
| 5 GHz streams | 2 — calculated from the maker's per-band rates, not a maker statement (see Stream-count math) | TP-Link |
| 5 GHz channel width (max) | 160 MHz (computed: HE160 in the maker's speed line) | TP-Link |
| 2.4 GHz channel widths | 20/40 MHz (maker's 2.4GHz reception-sensitivity list covers HE20 and HE40 only) | TP-Link spec, test data |
| Ethernet | 1× Gigabit WAN; 4× Gigabit LAN | TP-Link |
| Coverage (maker claim) | 3 bedroom houses | TP-Link |
| Antenna gain | 2.4 GHz: 1.95 dBi max (4.96 dBi beamforming directional); 5 GHz: 2.47 dBi max (5.48 dBi beamforming directional); dipole, 2 TX paths per band | FCC RF exposure report, §2.2, p6 |
Stream-count math
TP-Link does not state streams per band. We calculated them: maker's rate ÷ the standard 802.11ax rate of one stream at that width (1024-QAM, 0.8 µs guard interval) = n.
- 2.4 GHz: 574 Mbps ÷ 287 Mbps (one stream, 40 MHz) = 2
- 5 GHz: 2402 Mbps ÷ 1201 Mbps (one stream, 160 MHz; maker labels it HE160) = 2
The sum, 4, matches TP-Link's "4 Stream".
Cross-check: the FCC RF exposure report (§2.2, p6) lists 2 TX paths in each band, which agrees with 2 streams per band. That filing is for FCC ID 2AXJ4AX55V4 (Archer AX55, hardware v4); TP-Link's page we cite is the v1 page.
What this means for speed
- The WAN port is gigabit, so internet traffic through this router tops out near 949 Mb/s of TCP data (computed, RFC 6349 §4.1.1). A plan above 1 Gig is capped here.
- The 2402 Mbps 5 GHz figure is a PHY link rate at 160 MHz; a device without 160 MHz support links at a lower rate.
