How many devices can a router handle?

There is no single answer, because no standards body sets one. The “up to N devices” figure on a router box is the maker’s own number. Each company picks its own test conditions, and some do not say what they are.

Here is what the published figures show:

• eero says one eero “can support up to 128 devices,” but for streaming or other data-heavy use, you will “probably see best results using up to 30 devices with each eero.”
• Google says Nest Wifi Pro “can handle up to 100 connected devices per router,” assuming each device uses no more than 1 Mbps.
• Xfinity lists a connected-client limit per band: 75 per band on the XB7 gateway and 100 per band on the XB8 and XB10.
• ASUS says one Lyra mesh network supports “up to 60 clients.”

The eero gap, 128 versus 30, is the key point. A router can keep far more devices connected than it can keep busy. Phones in pockets and idle smart plugs barely use anything. Several video calls and downloads at once do.

For a sense of scale, Deloitte’s 2023 Connected Consumer Study found the average US household had 21 connected devices, down from 25 in 2021. That is well under every limit above. Holiday guests and new smart gadgets can push a home much higher, though. If some of those new gadgets belong to kids, see how to set up parental controls on Wi-Fi.

What do router makers say about device limits?

These are each maker’s stated figures as of October 2026. Treat them as marketing numbers, not tested guarantees, and note what each one is based on.

Sources: eero support and product pages, Google Nest Help, NETGEAR, TP-Link, ASUS and Xfinity, listed below.

Our math on the Xfinity figures: an XB7 can hold 75 × 2 = 150 clients in total, and an XB8 or XB10 100 × 3 = 300. That only works if devices spread across bands. Older devices that only use 2.4 GHz all land on one band.

TP-Link is the most candid. Its footnote says actual throughput, coverage and connected devices “are not guaranteed” and vary with your home and your devices.

Why can’t a router handle unlimited devices?

Three separate limits apply, and you can hit any one of them first.

1. Airtime. Every Wi-Fi device on a band shares the same radio channel and takes turns. More active devices means more waiting. This is the limit eero’s “30 devices” advice is about.
2. Client tables. The router’s radios and software track a fixed number of connected clients. Xfinity’s per-band caps are an example of this hard limit.
3. IP addresses. Each device needs an address from the router’s DHCP server, the feature that hands out addresses automatically. The pool is finite, as explained below.

Your internet plan is a fourth, shared limit. Every device online splits the same download and upload speed.

How many IP addresses does a home router have?

Home networks use private address ranges reserved by IETF RFC 1918 in 1996: 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16. Most home routers carve out a small piece, such as 192.168.1.0/24.

Our math for a /24 network: it holds 2⁸ = 256 addresses. Subtract one for the network address (.0) and one for broadcast (.255), and 254 are usable. The router itself takes one, which leaves 253 for devices.

Many routers hand out fewer than that by default. TP-Link’s TL-MR6400 user guide says its DHCP pool runs “from 192.168.1.100 to 192.168.1.199 by default.” Our math: 199 − 100 + 1 = 100 addresses.

Leases last 1,440 minutes (24 hours) by default on that model. A guest’s phone can hold an address for up to a day after they leave. Our take: if new devices suddenly cannot connect while others work fine, a full DHCP pool is a likely cause. Widening the pool in the router’s LAN or DHCP settings usually fixes it.

Do too many devices slow down Wi-Fi?

Yes, if enough of them are busy at the same time. Our guide to why your Wi-Fi is slow puts it simply: there is no single number, because it depends on your plan and what each device is doing.

What matters is simultaneous demand. Here is a holiday-weekend bandwidth budget, using published per-activity figures.

Our estimate: 10 + 15 + 6 + 20 = 51 Mbps download. Upload for the two calls is 2 × 3.8 = 7.6 Mbps. That fits easily on most plans, but it is all happening at once on the same channel.

The FCC’s Household Broadband Guide calls its tiers “rough guidelines.” It defines high use as basic tasks plus “more than one high-demand application running at the same time.” To size your plan, see how much internet speed do I need.

Our take: if the plan has headroom but everything still stutters, the bottleneck is usually Wi-Fi airtime or coverage, not the device count. Router placement matters a lot here; see where to place your Wi-Fi router.

Wi-Fi 5 vs. Wi-Fi 6 vs. 6E vs. 7: which handles more devices?

Newer generations are built for busy networks. Our take: the gains only apply to devices that support the same generation, though. An old laptop on a new router still talks the old way.

Wi-Fi 6E’s real benefit for a crowded home is room. Newer phones and laptops can move to 6 GHz, away from the 2.4 and 5 GHz bands where everything else sits. Whether Wi-Fi 7 is worth the price is covered in is Wi-Fi 7 worth it.

How many devices can a mesh system handle?

Usually more than one router, because each node is a separate access point with its own radios. Makers state this differently:

• Google rates each Nest Wifi Pro router and each Google Wifi point at up to 100 devices.
• eero states its figures per eero: up to 128 devices for one eero, or about 30 “with each eero” for heavy use.
• NETGEAR and TP-Link quote a single 200-device figure, on the Orbi 970 two-pack page and the Deco BE63 page, without saying whether it is per node or per system.
• ASUS quotes 60 clients for a whole Lyra network.

So read the fine print. A per-node figure grows as you add nodes. A per-system figure may not. Mesh also spreads devices out, so each node shares airtime with fewer of them.

Mesh does not add IP addresses. The main router still runs one DHCP pool for the whole home. For the trade-offs against a cheaper add-on, see mesh Wi-Fi vs. extender.

How do you see how many devices are connected to your router?

Every major brand has a device list in its app or admin page.

• NETGEAR Nighthawk: go to routerlogin.net, log in, and select Attached Devices on the Basic Home screen. It lists wired and wireless devices with their IP and MAC addresses.
• NETGEAR Orbi: go to orbilogin.com, log in, and select Attached Devices. Click Refresh to update it.
• ASUS: go to asusrouter.com or the router’s address, open Network Map, and click the Clients icon. The ASUS Router app also lists devices.
• eero: open the Devices tab in the eero app. eero says it “shows all active and recently active devices on your network.”
• Xfinity, other ISP gateways and other brands: check the provider’s or maker’s app, or the admin page, usually under a name like Connected Devices or Client List.

Our take: count what you find against your router’s stated figure and DHCP pool. If you see devices you do not recognize, change your Wi-Fi password and follow our home Wi-Fi security checklist.

How to handle more devices this holiday season

• Clear out the list. Remove old phones, retired gadgets and anything you do not recognize.
• Plug in what you can. Every desktop, console or hub on Ethernet frees airtime for everything else. See Cat5e vs. Cat6 for cable choices.
• Give guests their own network. A guest network keeps visitors’ devices off your main network. Our take: it is worth turning on before the house fills up.
• Widen the DHCP pool if new devices fail to connect while others work.
• Use the right band. Put newer devices on 5 or 6 GHz where you can, and leave 2.4 GHz for far rooms and simple smart gadgets.
• Consider non-Wi-Fi smart home gear. Some smart home devices use Zigbee, Z-Wave or Thread instead of Wi-Fi. See Matter vs. Zigbee vs. Z-Wave.
• Upgrade if the router is old. A Wi-Fi 5 router that no longer gets updates is a poor fit for a busy home. See how long a router lasts.
