インターネットは速いですか？
Is the internet fast?
Intānetto wa hayai desu ka?
Polite question. Use 'wa' (written は) to mark 'internet' as the topic. 'Hayai' means fast (or early, depending on context).
インターネットは遅いですか？
Is the internet slow?
Intānetto wa osoi desu ka?
Polite question. 'Osoi' is the antonym of 'hayai'. Useful if you suspect slow speed.
接続は安定していますか？
Is the connection stable?
Setsuzoku wa antei shite imasu ka?
Polite and slightly formal. 'Antei shite imasu' means 'is stable'. Good for business or hotel contexts.
インターネットは大丈夫ですか？
Is the internet okay? (reliable)
Intānetto wa daijōbu desu ka?
Polite question. 'Daijōbu' means 'okay' or 'no problem'. Often used to ask if the connection works.
Wi-Fiは繋がりますか？
Does the Wi-Fi connect?
Waifai wa tsunagarimasu ka?
Polite question. 'Tsunagarimasu' is the polite form of 'tsunagaru' (to connect). Use for Wi-Fi availability or connection success.

Useful pattern
To ask about internet speed, use the pattern: [Topic] wa [adjective] desu ka? For example, 'Intānetto wa hayai desu ka?' (Is the internet fast?). The topic marker 'wa' (written は) sets 'internet' as the topic. The adjective 'hayai' (fast) comes before 'desu ka' to form a polite question. To ask about reliability, replace the adjective with 'daijōbu' (okay) or use the verb 'tsunagaru' (to connect) in its polite form 'tsunagarimasu'. For stability, use 'antei shite imasu' (is stable). Note that Japanese adjectives do not change for gender or number, so 'hayai' works for any subject.
When to use it
Use the polite forms (desu ka, -masu ka) when asking staff at hotels, cafes, or in business settings. For example, at a hotel front desk: 'Intānetto wa hayai desu ka?' is appropriate. With friends or in casual settings, you can drop 'desu ka' and use rising intonation: 'Intānetto hayai?' (Internet fast?). To ask about reliability, 'Daijōbu desu ka?' is versatile and can mean 'Is it okay?' or 'Is it reliable?' depending on context. If you want to be more specific, 'Setsuzoku wa antei shite imasu ka?' asks directly about connection stability. Avoid using casual forms with strangers or superiors.
Listen to each line, then take one part and reply out loud.
すみません、インターネットは速いですか？
Excuse me, is the internet fast?Sumimasen, intānetto wa hayai desu ka?はい、速いですよ。でも、時々遅くなります。
Yes, it's fast. But sometimes it gets slow.Hai, hayai desu yo. Demo, tokidoki osoku narimasu.接続は安定していますか？
Is the connection stable?Setsuzoku wa antei shite imasu ka?はい、大体安定しています。Wi-Fiは繋がりますか？
Yes, it's mostly stable. Does the Wi-Fi connect?Hai, daitai antei shite imasu. Waifai wa tsunagarimasu ka?A little context goes a long way
In Japan, asking about internet speed is common in hotels and cafes. Politeness matters: use 'desu ka' with staff. Casual forms are fine with friends. Note that 'daijōbu' can also mean 'no thank you' in some contexts, so rely on tone. Many public Wi-Fi networks require passwords; asking 'Waifai wa tsunagarimasu ka?' is practical.
One thing to watch for
Using 'hayai' to mean 'fast' for internet speed but forgetting it also means 'early'. Saying 'Intānetto wa hayai desu ka?' is correct, but responding 'Hayai desu' might be ambiguous without context.
Try this instead: To avoid confusion, specify 'speed' with 'sokudo' (速度) or use 'nettowāku no sokudo wa hayai desu ka?' (Is the network speed fast?). However, in context, 'hayai' is understood as fast. For clarity, you can say 'Tsunagari ga hayai' (the connection is fast).
