An upstairs-downstairs layout across a floor ceiling can severely choke a single standalone router, especially on the high-frequency 6 GHz band used by Wi-Fi 6E(which has great speed but struggles to punch through thick floors and multiple walls).Instead of a single heavy-duty router downstairs, a multi-pack Wi-Fi 6E mesh system is usually the best approach: one unit connects to your modem downstairs, and the second node sits upstairs in your office to blast full speeds right to your desk.
Top Wi-Fi 6E options suited for multi-story coverage include:
If you prefer a traditional, powerful standalone router with massive external antennas, this is an exceptional pick. It offers great raw range and multi-gig ports, though if your floor blocks the signal too much, you may still see a drop upstairs. You can check current pricing on the Best Buy TP-Link Archer AXE7800 Page.
A tri-band mesh system that handles multi-story homes brilliantly. It uses a dedicated wireless backhaul (or can be wired if you have Ethernet in the walls) to ensure the upstairs node doesn't lose bandwidth communicating with the downstairs unit. Look over the details on the eero Pro 6E Store.
A sleek, easy-to-set-up tri-band Wi-Fi 6E mesh system designed to blanket multi-level homes seamlessly without sticking out in an office or living room.[1][2]
To help narrow down the best choice, tell me:
- What is your approximate square footage?
- Do you have Ethernet cables wired through the walls from downstairs to upstairs, or does it need to be 100% wireless?
- What is your internet service provider speed?

For your setup — office upstairs, router downstairs — I’d prioritize a Wi-Fi 6E mesh system over simply buying a more powerful single router. A mesh system lets you keep one unit downstairs and put a second unit closer to your upstairs office, improving coverage and reliability where you actually need it.
One important detail: Wi-Fi 6E adds a 6 GHz band for compatible devices, but that band has shorter range and struggles more with walls and floors than 5 GHz or 2.4 GHz. The placement of the upstairs mesh unit matters as much as the router's advertised speed.
My top Wi-Fi 6E picks
(Best overall for your layout)
TP-Link Deco XE75 Pro
$230–$400
Varies by pack size and retailer
A tri-band mesh system with a dedicated 6 GHz band and a 2.5 Gbps port. Two units are a good starting point for a downstairs router location and an upstairs office.
ASUS RT-AXE7800
$240
Listed price at Micro Center
A powerful single-router option with tri-band Wi-Fi 6E and AiMesh support. Consider it if your home is relatively small or open and you want to try one router before investing in a mesh system.
NETGEAR Nighthawk RAXE300
$295
Listed price at Walmart
A premium single-router alternative for fast local wireless connections and compatible 6E devices. It is less compelling than mesh if the upstairs floor is the main obstacle.
How I'd set it up
1. Downstairs — main unit
Connect the primary Deco to your modem and place it in an open, elevated spot rather than inside a cabinet.
2. Upstairs — second unit
Put the second unit on the landing or in a nearby room where it still receives a strong signal from downstairs, rather than at the far end of a dead zone.
If you can run an Ethernet cable upstairs, connecting the second unit by Ethernet is even better: it avoids relying on a wireless link between floors.
Let me narrow it down to the best buy
1. Approximate size of your home?
Under 1,500 sq ft
1,500–2,500 sq ft
2,500–3,500 sq ft
Over 3,500 sq ft
2. Budget for the router or mesh kit?
Under $200
$200–$350
$350–$500
$500+
3. Can you connect the upstairs unit to downstairs with Ethernet?
No, wireless only
Yes, Ethernet is possible
Not sure
4. What separates the floors?
Wood framing and drywall
Concrete, brick, or masonry
Not sure

These details will help determine whether a single router is enough or whether a two-unit mesh kit is worth the extra cost.

For your setup, I’d prioritize a Wi-Fi 6E router with strong multi-floor coverage, or a Wi-Fi 6E mesh system rather than simply buying the router with the highest advertised speed. Since your office is on a different floor from your modem, the biggest challenge is getting a strong signal through floors and walls while maintaining enough bandwidth for fast downloads, video calls, and large file transfers.
One important detail: Wi-Fi 6E's 6 GHz band is fast but has shorter range and less ability to penetrate obstacles than 5 GHz or 2.4 GHz. You'll want a system that can fall back to those bands or use a mesh node near your office.
My top Wi-Fi 6E recommendations
1. TP-Link Deco XE75 Pro
(Best overall for most homes)
Tri-band mesh · 2- or 3-pack
A strong fit for a multi-floor home. Multiple units work together to extend coverage, and the Pro model includes a 2.5 Gbps port for faster wired connections. TP-Link advertises coverage up to 5,500 sq. ft. for two units or 7,200 sq. ft. for three.
Best for: Getting reliable Wi-Fi in your upstairs office without replacing the system again when you add more devices.

2. ASUS ZenWiFi Pro ET12
Premium mesh · Multi-gigabit networking
A high-performance option with two 2.5 Gbps ports per unit and flexible wired or wireless mesh connections. Independent testing found particularly strong long-distance performance, although the number and placement of nodes still matter.
Best for: A demanding office setup, large file transfers, and a home with lots of connected devices.

3. ASUS RT-AXE7800
Single router · Expandable with AiMesh
Worth considering if you'd rather start with one router and add a compatible ASUS mesh node later. It supports Wi-Fi 6E and ASUS AiMesh, but a single router may struggle with a distant office separated by dense floors or walls.
Best for: A moderate-size home where you want to avoid buying a full mesh kit upfront.

How I'd set up your home
1. Main mesh unit
Connect it to your modem on the modem's floor, ideally in an open, elevated location.
2. Second mesh unit
Place it on the floor between the main unit and your office, where it still receives a strong signal.
3. Your office
Connect over Wi-Fi, or use Ethernet from the nearby mesh unit if your computer needs a more stable connection.
If you can run Ethernet between floors, a wired connection to an upstairs access point is even better: it avoids losing wireless bandwidth between mesh units.
Let’s narrow it down to the right system
The best choice depends on the size and construction of your home. Roughly how large is it, and how many floors are you trying to cover?
1. Approximate home size
Under 1,500 sq. ft.
1,500–2,000 sq. ft.
2,000–3,000 sq. ft.
Over 3,000 sq. ft.
2. Number of floors
2 floors
3 floors
4 or more floors
3. Budget for the complete setup
Under $200
$200–$400
$400–$700
$700+
4. Can you run Ethernet between floors?
No, wireless only
Yes, Ethernet is available
Possibly, if worthwhile
5. Internet plan speed (if known)
Under 300 Mbps
300–500 Mbps
500 Mbps–1 Gbps
Over 1 Gbps

Covering multiple levels where your office is separated from the modem by a floor or thick ceilings means a single traditional router—even a powerful one—will likely struggle with the 6 GHz and 5 GHz signal attenuation. For multi-floor layouts, a tri-band mesh Wi-Fi 6E system with dedicated or flexible backhaul is the gold standard to ensure your office gets maximum throughput without major drops.
Here are the top Wi-Fi 6E recommendations tailored for multi-floor range and performance:

Best for Power Users & Performance
- Details: These tri-band Wi-Fi 6E mesh nodes provide incredible range, robust AiMesh customization, and multi-gig ports. They excel at maintaining high backhaul speeds between floors, making them ideal if you are transferring massive files or video conferencing heavily from your remote office.[1][2]
To help narrow down the ideal setup, let me know:
- What is the approximate square footage of your home?
- Does your internet plan exceed 1 Gigabit per second?
- Is there any possibility of running an Ethernet cable between floors to wire the nodes together?
Also asked as
- My router is on the lower level and my office is on the upper level. What is a reliable Wi-Fi 6E router for improving speed and coverage across these floors?
