Below are reliable, business‑friendly hotels in Singapore known for good Wi‑Fi and solid business facilities (locations, why they’re good for work, and sources showing their connectivity / business services). If you want I can check real‑time rates/availability for specific dates.

Top picks (by area)

• Mandarin Orchard (Orchard Road) — excellent for business travellers: free in‑room “handy” smartphone with unlimited 4G data for guests and consistently high measured in‑hotel speeds in independent tests (one review/speed roundup recorded ~273 Mbps down / 294 Mbps up). Strong MICE capacity and direct access to shopping/Orchard attractions. (businesstraveller.com)

• Conrad Centennial / Conrad Singapore Marina Bay (Marina Bay / Suntec) — a long‑standing business hotel with a full business centre, meeting rooms and an executive lounge; reviewers/independent tests report fast premium/executive Wi‑Fi (one measured ~40 Mbps). Good location for the CBD, Suntec and convention business. (fivestaralliance.com)

• The Fullerton Hotel Singapore (Marina Bay/CBD) — classic CBD hotel with a 24‑hour business / financial centre and meeting/boardroom facilities; independent reviews and tests show solid in‑room speeds in the 20–25 Mbps range which is reliable for video conferencing and bulk uploads. (businesstraveller.com)

• Pan Pacific Singapore (Marina Bay / Marina Centre) — marketed as business‑friendly with meeting spaces and guaranteed meeting connectivity; independent tests show adequate speeds for remote work (~19 Mbps in one roundup). Good for clients with meetings in Marina Bay / Suntec. (panpacific.com)

• Shangri‑La Singapore (Tanglin / near Orchard) — large business facilities, dedicated business centre and offers that advertise “fast Wi‑Fi everywhere”; independent testing places it among hotels with reliable mid‑range speeds. Good for quieter, executive stays outside the CBD hubbub. (shangri-la.com)

• M Social / boutique business hotels (Orchard / Robertson Quay) — some boutique hotels (e.g., M Social) have surprisingly fast measured Wi‑Fi (one test showed ~46 Mbps) and can be good low‑latency options if you prefer smaller properties. If you value raw speed, check recent speed tests or ask the hotel about their “premium”/executive network. (milelion.com)

Notes on the speed data and sources

• The speed figures above come from recent independent hotel Wi‑Fi tests and published hotel descriptions/reviews (speed can vary by floor, time of day and whether you’re on a standard vs. premium/executive network). The independent roundup I used reports per‑hotel Speedtest results collected during reviewer stays; hotel pages and business reviews confirm business centres and premium network options.

Short checklist when booking for business Wi‑Fi

• Ask whether the hotel offers a “premium” or executive Wi‑Fi (some hotels reserve the fastest network for executive‑lounge guests or charge a small fee).
• Request a wired LAN port in the room or a room near the business floor if you need the lowest latency and highest reliability.
• If you’ll run large uploads or host video calls, ask the hotel for an SLA/expected bandwidth for meeting rooms or business centre lines.
• Bring a phone hotspot (local eSIM or rented 4G/5G device) as a backup for critical meetings.
• Test the connection on arrival (speedtest.net) and ask staff to switch you to the premium/business network if needed.

If you’d like, I can:

• Narrow this list to a specific neighbourhood (Orchard, Marina Bay, Sentosa, Changi) or budget; or
• Check current executive‑room / premium‑Wi‑Fi availability and rates for dates you plan to travel.
