Check the connection near your existing router and try a better router position before buying anything. If a language lesson still buffers in a room behind thick walls, a mesh system with a node you can place nearer that room is more relevant than a single router chosen for its advertised speed. Wi-Fi 7 and multi-gig ports are worth considering only where your devices, broadband service or wired network plans can use them.
If Wi-Fi works near the router but struggles in a room beyond thick brick walls or floors, focus on whether an additional Wi-Fi point can be positioned nearer the room. Ofcom notes that brick internal walls can make whole-home coverage harder.
If lessons coincide with streaming, downloads or gaming elsewhere at home, compare the connection near the router with the one in the lesson room. Ofcom advises that slow Wi-Fi can reflect the router, device, distance, walls or interference rather than a fault with the broadband line.
If you can run Ethernet to a useful node position, consider wired backhaul or a mountable access point. TP-Link lists combined wired and wireless backhaul for Deco BE65, while Deco BE65-PoE supports wall or ceiling mounting and Power over Ethernet; those options still depend on where cabling and power can be arranged.
For a language lesson affected by thick internal walls, establish whether the problem occurs throughout the connection or mainly in the lesson room. That distinction determines whether to investigate the broadband service, adjust the existing setup or plan positions for mesh nodes.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage through walls | Compare Wi-Fi in the lesson room with Wi-Fi near the router; identify a possible intermediate mesh-node position. | If my lesson only struggles beyond the thick walls, I need a Wi-Fi point closer to the room without placing it where its own connection is weak. Around 50% of consumers put coverage first. |
| Broadband and competing use | Test at lesson time near the router and in the lesson room; note whether heavy household activity coincides with disruption. | When lessons falter even near the router, I want to know whether the broadband connection or other activity is involved before replacing Wi-Fi equipment. For around 30% of consumers, that diagnosis is the primary concern. |
| Installation and expansion | Confirm how your service connects to the router, whether Ethernet reaches a useful node position and what support the provider offers for your proposed setup. | If a better Wi-Fi position requires cabling or a different router setup, I need equipment I can install and use with my connection. Installation flexibility comes first for around 20% of consumers. |
A wireless speed figure does not tell you how the connection will behave across your walls, and a Wi-Fi upgrade cannot increase the speed of the underlying broadband service. Ofcom also identifies distance, interference and the device itself as factors in Wi-Fi performance.
Test beside the router and in the lesson room, then assess placement and possible backhaul routes before choosing a higher Wi-Fi specification.
Ofcom notes that brick internal walls can obstruct Wi-Fi. A mesh kit offers additional positions for Wi-Fi points, but its nodes must still be able to communicate across the home.
Work out where an intermediate node could sit. If you can run Ethernet between suitable positions, compare systems with wired backhaul rather than relying solely on a wireless link through several barriers.
A third-party router may take more work to configure, and the broadband provider may not be able to help with problems involving equipment it did not supply.
Before ordering, confirm how your broadband connection reaches the router or fibre optical network terminal, check the proposed system’s compatibility and ask what support your provider offers.
Keep the provider router available if you may need it to isolate a connection fault.
For eero Pro 7, eero distinguishes its optional eero Plus subscription features from the router’s core operation.
Check which security and parental-control functions are available without a subscription, and decide whether the optional features matter for your household.
The Deco BE65 and Deco BE65-PoE are relevant when node placement and a possible Ethernet route shape the choice.
The Orbi 970 is a higher-capacity Wi-Fi 7 mesh option to assess when several devices share a connection or the network has broader expansion requirements.
The eero Pro 7 is relevant to households considering an expandable Wi-Fi 7 mesh setup.
These three-unit mesh systems are relevant if the lesson room remains weak after you check the existing connection and can position another unit nearer the room. Compare the space available for each unit and any Ethernet plans; a Wi-Fi specification cannot guarantee reception through your particular walls.

The three-unit format gives you positions to plan around a weak lesson room. Check that an intermediate unit can connect effectively to the main unit and that the system suits your broadband setup.

Consider this three-pack when you can position a unit between the router and lesson room, particularly if you are also planning an Ethernet route between units.
TP-Link specifies four 2.5 Gbps ports per Deco BE65 unit and combined wired and wireless backhaul. Check your proposed node positions and broadband compatibility; neither the ports nor the Wi-Fi designation establishes performance through your walls.

This three-unit system offers several positions for a Wi-Fi point when the lesson room is distant from the main router. Its listed variant is dual-band with 2.5 Gbps Ethernet.
Check where the units could sit and whether the system suits your broadband setup. Do not assume its Ethernet ports establish a wired-backhaul option without confirming the configuration you intend to use.
Not automatically. Ofcom explains that Wi-Fi signals weaken as they pass through objects and that brick internal walls can make coverage harder. If a better position for the existing router does not help, consider whether a mesh node can sit nearer the lesson room rather than relying on a higher advertised speed.
Try a central, raised position for the main router where practical, away from major obstructions and potential interference. Then test the lesson room and any proposed intermediate node position: a node nearer the room also needs a usable connection back to the network.
You may be able to, but confirm your connection method, the new system’s compatibility and your provider’s support arrangements before buying. A third-party setup may be harder to troubleshoot with the provider than its supplied router.
Not necessarily: address weak coverage and check the broadband connection first. Wi-Fi 7 features or multi-gig ports are more relevant when compatible devices, a suitable broadband service or a wider network plan can use them; they do not guarantee a stable connection through a specific set of walls.
Check that the product is intended for the Great Britain market and that the seller can provide clear product and support information. GOV.UK describes the Radio Equipment Regulations 2017 for Great Britain as addressing radio-equipment safety, electromagnetic compatibility and protection of the radio spectrum.
