Roblox does not support normal offline play. You need a working internet connection to sign in, download or validate an experience, and join its game server—but that connection does not have to be Wi‑Fi. Mobile data, a phone hotspot, Ethernet, or another authorized network may work.
Does Roblox need Wi‑Fi or the internet?
Wi‑Fi is only one way to reach the internet. Roblox needs internet access, not specifically a Wi‑Fi signal. A device can show a Wi‑Fi icon while the router has lost its ISP connection, a captive portal still needs sign-in, DNS is failing, or a firewall is blocking Roblox.
Roblox’s mobile guidance lists an internet connection of about 4–8 Mb/s and recommends Wi‑Fi when 3G/4G is unstable. That makes Wi‑Fi a preferred connection in many situations, not an exclusive requirement.
Why Roblox cannot normally be played offline
Roblox is a server-based platform rather than a collection of self-contained games. When you press Play, the client generally needs to:

- Redemption: Online only. Robux cards can only be redeemed in a browser at Roblox.com/redeem. They cannot be redeemed in the Roblox mobile app or any video game console.
- Roblox is an immersive platform for connection and communication. Every day, millions of people come to Roblox to create, play, work, learn, and connect with each other in experiences built by our global community of creators.
- Get more with every Roblox Gift Card! From now on, when you redeem a Roblox gift card, you get up to 25% more Robux. Perfect for gaming, creating, and exploring- more Robux means more possibilities!
- Deck out your avatar and unlock additional perks in your favorite experiences when you use Roblox Gift Cards to purchase Robux (Roblox's virtual currency).
- Each gift card grants a free virtual item upon redemption.
- Authenticate your account and session.
- Connect you to a Roblox-hosted experience server.
- Retrieve or validate maps, scripts, textures, sounds, and updates.
- Synchronize movement, interactions, inventory, chat, and other live game state.
- Apply permissions, safety systems, and content controls.
These are practical consequences of Roblox’s online architecture; Roblox’s connection documentation confirms that Play mode requires communication with its servers. Previously downloaded or cached files therefore do not create a supported offline mode.
Can I play Roblox with mobile data or a hotspot?
Usually, yes. Turn on cellular data, allow Roblox to use it, and retry the experience. On iPhone or iPad, check Roblox’s cellular-data permission; on Android, check its mobile-data permission and whether Data Saver is restricting it. Menu names vary by operating-system version.

Mobile data can be less reliable than home broadband because of weak signal, congestion, latency, throttling, or a limited allowance. Large experiences and updates may consume substantial data. A phone hotspot can connect a tablet, computer, or console, but it may increase latency, drain the phone battery, disconnect when cellular coverage changes, or be limited by your carrier’s tethering policy.
What to do when Wi‑Fi is connected but Roblox says “No Network”
- Open another website or online app to test whether the connection reaches the internet.
- On public, hotel, library, or school Wi‑Fi, complete the browser sign-in page.
- Close and reopen Roblox, then restart the device.
- Restart the router if other devices also fail.
- Try mobile data, a phone hotspot, Ethernet, or another trusted network.
- Temporarily test without a VPN, ad blocker, or security filter. Do not leave antivirus or firewall protection disabled; configure an allow rule instead.
- Check Roblox’s network permission, update the app and operating system, and verify the device’s date and time.
- Reinstall Roblox if its local installation may be corrupted.
- Contact your internet provider or Roblox Support if the problem continues.
Roblox has documented an iOS “No Network” message that could appear even while Wi‑Fi was connected, so the message does not always mean the Wi‑Fi radio is off. See the official iOS notice.

What Error 279 / ID 17 means
Error 279 (ID 17) means the Roblox client could not establish a connection to the game server. It is not automatically proof of a Roblox-wide outage. Common causes include an unstable connection, blocked game traffic, firewall or antivirus interference, missing permissions, a corrupted installation, or a problem with one particular experience or server.
If other experiences work, the failing experience may be broken, empty, unusually large, or temporarily unavailable. A slow connection may eventually load content; no internet connection cannot establish the required session.

What if a school, workplace, or public network blocks Roblox?
Some networks permit ordinary web browsing but block game traffic, and firewalls can prevent the client from reaching Roblox. Roblox’s support pages discuss firewall and router issues and list a current UDP range of 49152–65535; this detail is mainly for an administrator or technically capable adult because port requirements can change.
Do not bypass school, workplace, or parental restrictions. Ask the network administrator, use an authorized personal connection, or play later on a permitted network. A VPN is not a guaranteed fix and may itself be blocked.

Can Roblox Studio work without internet?
Some local building or editing may be possible when Play mode cannot connect. Roblox explicitly distinguishes Build or Edit access from Play during connection problems. That does not mean Studio has a complete offline mode: publishing, collaboration, cloud saves, account functions, online assets, and online testing may require internet access.
Is there any real way to play Roblox completely offline?
Not through a supported normal Roblox experience. Be wary of “offline Roblox” downloads, modified clients, or tools promising to bypass login or servers. They can steal accounts, install malware, or violate Roblox rules. Cached game files are not an official offline feature.
Quick answer by situation
| Situation | Likely result |
|---|---|
| Wi‑Fi off, mobile data on | May work if signal, permissions, and data allowance are adequate. |
| Wi‑Fi off, phone hotspot on | May work, with possible latency, battery, and data-limit issues. |
| Ethernet connected | May work on a compatible computer or console. |
| Wi‑Fi icon visible but no usable internet | Play mode will generally fail. |
| No internet anywhere | Normal Roblox Play mode will not work. |
| Roblox Studio open offline | Some local editing may be possible; online features may not. |
The key distinction is simple: Roblox requires a working internet connection, not specifically a Wi‑Fi network.
