Working from home does not need much bandwidth. It needs consistency, and those are different engineering problems. A video call uses roughly 2 to 4 Mbps in each direction. What it cannot tolerate is packets arriving late, and a speed test cannot see that at all — which is why your connection can "test fine" and still embarrass you twice a week.

To not be competing with you
Per simultaneous activity. Note how little bandwidth matters and how much consistency does.
Scroll the table sideways to see every column.
Two things stand out. Upload is the scarce resource, and one cloud backup can wreck everything else while barely denting a download speed test. And nothing on that list needs a fast internet plan — the constraint is almost always the last thirty feet and the household.
The order to fix things in
Wire the desk. Free of caveats and it removes almost every cause at once: no interference, no retransmission from weak signal, no roaming, no band-steering decisions. Ethernet if you can run it; MoCA over an existing coax outlet if you cannot; powerline as a fallback. If calls are part of how you earn, this is not an indulgence, it is the single highest-value change available.
Stop the household competing with you. Set consoles and PCs to patch overnight, pause cloud backups during working hours, and turn on QoS to prioritize real-time traffic over bulk transfer. Free.
Move the desk device to 5 or 6 GHz and keep it there. Less crowded, and far less prone to the burst interference that kills calls. Free.
Fix the office's signal. If wiring is impossible, put a radio in or near the office — a mesh node with a clean backhaul, or a wired access point if you can reach the room even if you cannot reach the desk.
Then, if still needed, upgrade the router. Last, because it is the most expensive and least often the actual cause.
Try this first
Diagnose with the call's own statistics, not a speed test
Teams and Zoom both expose live jitter and packet loss during a call. Packet loss above about 1 per cent, or jitter above roughly 30 milliseconds, is where calls visibly degrade. Run a continuous ping alongside a call and watch for spikes rather than the average — steady 20 ms with occasional 800 ms spikes is the signature of a marginal wireless link. The full diagnostic is here.
Building the setup properly
The desk
Wired, if there is any way to achieve it. A dock or a USB Ethernet adapter costs very little if the laptop has no port. If the room has a coax outlet, two MoCA adapters give you gigabit-class Ethernet over shielded cable with no drilling.
The office room
If the desk cannot be wired but the room can be reached, a ceiling access point in or beside the office is the best wireless answer that exists. Failing that, a mesh node with a dedicated backhaul band — the office node's uplink quality is what determines your call quality, so this is the one place not to economize on backhaul.
The household
QoS matters more in a working household than anywhere else on this site, because the contention is predictable: it happens at 4pm when school ends and at 8pm when everyone is home. A router with real per-device prioritization lets you make the work laptop reliably win. Systems that put QoS behind a subscription are worth avoiding for exactly this reason.
The fallback
If your job genuinely depends on it, have a phone hotspot tested and ready. Not as infrastructure — as the thing you switch to during an outage, having already confirmed it works rather than discovering it at the worst moment.
What not to buy
A faster internet plan. A call needs a few megabits. Unless your upload is genuinely under about 10 Mbps, the plan is not your problem — how to check.
A wireless extender for the office. It roughly halves throughput and adds latency, which is the opposite of what calls need.
A mesh system, if only the office is bad. One wired access point is cheaper and better.
A flagship router to fix a far room. Range has not improved across recent generations; you need a radio closer to the room.

What it gets right
+A ceiling-mounted access point solves coverage better than any number of extenders, because the signal goes down through one floor instead of sideways through five walls
+2.5 GbE uplink means the wire is never the limit
+No subscription, and the controller software is free

Common questions
What internet speed do I need to work from home?+−
Far less than most people assume — a group video call uses roughly 2 to 4 Mbps each way, and remote desktop about 5 to 10 Mbps. The constraint is almost never total bandwidth but upload capacity being shared with something else, plus jitter on a weak wireless link.
Is Ethernet worth it for working from home?+−
Yes — it is the single highest-value change available. A wired connection has no interference, no retransmission from weak signal, no roaming and no band-steering decisions, which removes almost every cause of dropped calls at once.
Why do my calls drop when my speed test is fine?+−
Because a speed test measures how much data you can move over ten seconds, while a call needs data to arrive evenly. On a marginal link, failed packets get retransmitted quickly enough to keep the average high but too late for a real-time stream, so frames get dropped.
Does QoS actually help with home working?+−
Yes, for the household-contention case specifically. It cannot create bandwidth, but it can stop a game download or a cloud backup from starving a call — which is the most common cause of the "you are freezing" complaint.
