Hits both at once

The upload budget for two people

Calls are limited by upload, because that’s the narrow side of the line and it’s where your video goes. Here’s the arithmetic using the vendors’ figures and Ookla’s Q1 2026 US median upload of 21.46 Mbps (third-party, not ours).

“Together” is each figure × 2 (kbps converted to Mbps for Teams); “left” is the Ookla median minus that. Your own line may be lower than the median, especially at busy hours. Starlink’s spec for the lower Residential tiers: Residential 100 Mbps: download capped at 100 Mbps (spec 80-100 Mbps), upload 15-35 Mbps.

So two calls fit, with room. The danger is that a file upload doesn’t share politely: it takes whatever is free and fills the queue, and both calls freeze together. That’s why the rules below matter more than the plan.

Household rules that keep both calls clean

• No big uploads during work hours. Cloud backups, photo sync from phones, and video uploads wait until evening or overnight.
• Share calendars. When both of you have an important call at once, agree in advance who turns off video if the line struggles. Audio needs very little: Teams recommends 58 kbps.
• Schedule game and system updates overnight. Console and PC updates are large. Most consoles and Windows let you set update hours.
• Live streaming (Twitch, YouTube) is an upload. Keep it out of work hours, like any other big upload.
• Set an upload limit on the router. Smart queue management (SQM) keeps call packets moving even when someone breaks the rules. How.
• Watch busy evening hours. If one of you takes calls in the evening rush, network priority matters: Starlink says the lower Residential tiers are more likely to slow down in congestion than Residential Max (checked Oct 5, 2026).

Two desks, two cables

Wi-Fi problems double with two workers: two laptops competing for airtime, often in rooms far from the router. Run Ethernet to both desks. Starlink’s Router 3 has 2 ports (checked Oct 5, 2026); for more wired devices, add a small network switch. On older kits: The older Gen 2 router has no built-in Ethernet ports; an Ethernet adapter is sold separately.

If a cable can’t reach one desk, give that person the strongest Wi-Fi spot or a mesh point with a wired backhaul, and let them be the one who drops video first.

Busy households also have many devices. CGNAT plans are limited to 1,200 sessions open connections at once. Two workers rarely get near that on their own; add smart-home gear, a gamer and a few streaming boxes and it’s worth knowing about.

When it drops for both of you

One line means shared fate: an outage stops both calls at the same moment. Plan for that before it happens.

1. Decide who gets the backup first if it can only carry one call well.
2. Size the backup for two. A phone hotspot that holds one call may not hold two. Check the backup’s signal and data plan against the budget table above.
3. Automate the switch. A dual-WAN router moves both of you to the backup in seconds instead of each of you fiddling with a hotspot. The Failover Builder asks how many people work at once.
4. Log outages. The Starlink app’s Statistics page lists outages while you’re on its router. Note the times; it helps when talking to employers and support.
