How to Block Roblox on Your Router (Every Major Brand, 2026)

Blocking Roblox on one computer takes ten minutes, and then your child plays it on the iPad. Router-level blocking is the answer to that: one rule, applied once, that covers every phone, tablet, console and laptop on your Wi-Fi — including devices you cannot install software on.

It is also the method most commonly oversold. A router blocks traffic that crosses your router, which means it stops working the instant a device leaves the house or switches to cellular data. This guide covers the exact menu path for each major router brand, the DNS approach that works when your router's own controls are too weak, how to schedule it rather than block it outright, and an honest account of where router blocking fails.

For device-level methods, see the main guide on how to block Roblox on PC, laptop and Mac.

What to Block: The Two Entries That Matter

Before opening any router menu, know what you are entering. Roblox spans several hostnames, but at router level almost all of them collapse into two wildcard rules:

*.roblox.com
*.rbxcdn.com

If your router only accepts plain domains without a wildcard, enter roblox.com and rbxcdn.com — most router firmware treats a bare domain as covering its subdomains. If it offers keyword blocking rather than domain blocking, the single keyword roblox works, with the side effect of blocking any URL containing that word.

The full breakdown of every hostname and what each one does is in our Roblox domains to block reference.

Which Router Approach Should You Use?

Approach Covers Setup time Survives a VPN Survives leaving home
Built-in URL/keyword filter All Wi-Fi devices 5–10 min No No
Custom DNS on the router All Wi-Fi devices 10 min No No
Per-device profile + schedule One named device 10–15 min No No
Device-level software That device only 10 min Depends Yes

The table makes the trade explicit. Router methods are broad but shallow; device methods are narrow but travel. For a family desktop or a console, router blocking is genuinely sufficient. For a laptop or phone that leaves the house, it is a second layer and never the only one.

Netgear (Nighthawk, Orbi)

Netgear's own filtering lives under a feature called Access Control or, on newer firmware, Netgear Armor.

  1. Browse to routerlogin.net or 192.168.1.1 and sign in (the default password is password unless you changed it — change it)
  2. Open Advanced > Security > Block Sites
  3. Set Keyword Blocking to Always
  4. In Add Keyword, enter roblox.com, click Add Keyword, then repeat for rbxcdn.com
  5. Click Apply

To apply it to one child's device rather than the whole house, use Block Sites > Allow trusted IP address to visit blocked sites and enter the IP of your own computer, so the rule covers everyone except you.

On Orbi mesh systems the same page is under Advanced > Security > Block Sites on the router unit; satellites inherit it automatically.

TP-Link splits this between two different interfaces depending on hardware.

Archer routers (web interface):

  1. Go to tplinkwifi.net or 192.168.0.1 and sign in
  2. Open Advanced > Parental Controls
  3. Create a profile, name it after your child, and add their devices under Devices
  4. Under Content Filter, switch to Blocklist and add roblox.com and rbxcdn.com
  5. Optionally set Time Limits and Bed Time on the same profile

Deco mesh (app only): open the Deco app, tap More > Parental Controls, create or select a profile, then Filter Level > Custom > Blocked Websites and add the two domains. Deco's HomeShield tier gates some filtering behind a subscription; the manual blocklist is available on the free tier.

Asus (RT series, ZenWiFi)

Asus routers include AiProtection, powered by Trend Micro, alongside a plain URL filter. The plain filter is the one you want — it is free and does not require enabling cloud scanning.

  1. Sign in at router.asus.com or 192.168.1.1
  2. Open AiProtection > Parental Controls > Web & Apps Filters
  3. Accept the terms if prompted, select the client device, and choose a category — or
  4. For exact domains, use Firewall > URL Filter instead: set Enable URL Filter to Yes, set filter table type to Blacklist, and add roblox.com and rbxcdn.com

Asus's URL Filter historically only inspects unencrypted requests, which limits it against HTTPS sites. If it does not hold, use the DNS method below instead — on Asus that is WAN > Internet Connection > DNS Server.

Eero

Eero has no per-domain blocklist on the free tier. Blocking a specific site requires Eero Plus (marketed as Eero Secure), which adds a Block/Allow list.

With Eero Secure: open the eero app, tap Discover > eero Secure > Block & Allow Sites > Block Site, and add roblox.com. Without it, your options are to create a profile for the child, pause the internet on a schedule, or set custom DNS at Settings > Network Settings > DNS > Custom and point it at a filtering resolver (see below).

Google Nest Wifi

Google Nest Wifi does not support blocking individual domains at all. Its parental controls offer SafeSearch and a broad adult-content filter, plus per-device pause and schedules.

To block Roblox specifically you need the DNS route: Google Home app > Wi-Fi > Settings > Advanced networking > DNS > Custom, then enter a filtering resolver's addresses. Note that this applies to the whole network, not one child.

Xfinity, Spectrum and ISP-Supplied Gateways

ISP gateways vary widely and many have had their filtering features removed in favour of an app.

Xfinity: use the Xfinity app > WiFi > View WiFi equipment > Advanced settings > Blocked sites, and add roblox.com. Xfinity's xFi Complete tier adds per-profile scheduling.

Spectrum: the My Spectrum app offers device pausing but no domain blocklist. Use DNS filtering or put your own router behind the gateway.

If your gateway offers nothing useful, the cleanest fix is to put a router you control behind it and run the ISP box in bridge mode.

The DNS Method: Works on Any Router

When your router's built-in filtering is missing, weak, or behind a paywall, changing the router's DNS server achieves the same result and often does it better.

Every device on your network asks your router where to find roblox.com. Point the router at a filtering resolver instead of your ISP's, and that resolver simply refuses to answer for the domains you have blocked.

  1. Sign in to your router and find WAN, Internet, or Network Settings
  2. Find DNS Server and switch from Automatic to Manual
  3. Enter the two addresses your chosen filtering service provides
  4. Save and reboot the router
  5. On each device, run ipconfig /flushdns (Windows) or sudo dscacheutil -flushcache (Mac)

Free filtering resolvers such as OpenDNS and CleanBrowsing include gaming categories, and running your own Pi-hole gives you exact per-domain control. The regex syntax for Pi-hole and AdGuard Home is in the domains reference.

One caveat that matters: modern browsers increasingly use DNS-over-HTTPS, which sends lookups to Cloudflare or Google directly and skips your router's DNS entirely. Chrome and Firefox both do this. If your DNS filter appears to be ignored, that is usually why, and it has to be turned off per browser.

Schedule It Instead of Blocking It

Blocking Roblox outright turns you into the enemy. Most routers can instead allow it during a window, which is easier to defend and easier for a child to accept.

On TP-Link this is Parental Controls > Time Limits on the profile. On Netgear it is Block Sites > Per Schedule. On Asus it is the Time Scheduling tab in Parental Controls. On eero it is a profile schedule. The pattern is the same everywhere: create a device profile, attach the blocklist, then attach a schedule to the profile rather than to the rule.

If the argument is really about hours rather than the game itself, our guide on setting a bedtime on the computer covers the scheduling side properly.

Where Router Blocking Fails

Four failure modes, all of them common:

Mobile data. A phone with a cellular plan never touches your router. Neither does a laptop tethered to that phone. This is the single biggest hole and there is no router-side fix for it.

Leaving the house. School Wi-Fi, a friend's house, the library — your rules do not travel with the device.

VPNs. A VPN app encrypts everything and tunnels it past your filter. Router-level VPN blocking is possible on some firmware but is a constant arms race. See can a VPN bypass parental controls.

Encrypted DNS. As above — a browser using DoH silently ignores your router's DNS.

The pattern is that every router method is a network control, and a child's device is only sometimes on your network. That is why device-level allowlisting exists: the rule lives on the machine, so it applies on school Wi-Fi and on a hotspot exactly as it does at home. That approach is covered in parental controls kids can't bypass.

Frequently Asked Questions

Will blocking Roblox on my router block it on my child's phone?

Only while the phone is on your Wi-Fi. The moment it switches to mobile data, Roblox works again. Phones need a control installed on the device itself.

Can my child tell that I blocked it at the router?

Roblox will show a connection or network error rather than a "blocked by parent" message, so it looks like an outage. Many parents prefer to say plainly that they blocked it — a mysterious failure invites troubleshooting, and troubleshooting is how bypasses get found.

Does blocking Roblox at the router affect the Xbox or PlayStation?

Yes, and this is router blocking's real advantage — consoles accept no filtering software, so the network is the only place you can control them.

My router has no site-blocking option at all. What now?

Use the DNS method above, which works on any router that lets you set a DNS server. If it does not even allow that, add your own router behind the ISP gateway.

Should I block Roblox at the router or on the computer?

Both, if the device leaves the house. Router blocking covers consoles and tablets; device-level control covers the laptop on school Wi-Fi. Neither alone covers everything.
