Fiber internet reaches most of the areas families settle in, places like Canggu, Ubud, Umalas, Sanur and Denpasar. Speeds are usually enough for video calls, uploads and streaming without much trouble. Once you get further out, into the hills or quieter coastal spots, connections rely more on mobile networks, which are still decent but less consistent. If a fast, stable connection is non-negotiable for your job, it's worth checking exactly which network reaches a property before signing a lease, not just asking if there is wifi.
Power cuts happen, especially during the rainy season from around October to March, and they take the router down with them. Most parents who work daily video calls keep a local SIM or eSIM with a solid data plan as backup, and some keep a small power bank or UPS for the router so a short outage doesn't kill a call mid-meeting. It's common practice to test the wifi speed at a villa or house during a trial stay or the first days there before committing to a longer rental, since listing descriptions aren't always accurate.
Coworking spaces are easy to find in the family hubs, and many parents use them precisely because the internet there tends to be more reliable than a home connection, with the added benefit of a change of scene. If you're working from home with young kids around, plan calls around nap times or have a partner or helper on hand, since a toddler wandering into frame is a daily reality here as much as anywhere else. Time zone gaps with your home country matter too, so many parents block their calendar around Bali hours and treat early morning or late evening as the overlap window for calls back home.
