I work at a large restaurant where servers use handheld devices to send orders. The owner added several networking devices to improve coverage because the building can hold more than 300 people, but the handhelds now sometimes stop working. They may still appear connected to Wi‑Fi, while the wired computers on the same network continue working normally. The owner is not very familiar with networking, so I'm trying to figure out whether these are actually routers, access points, boosters, or mesh units and what setup would prevent the disconnects.

The network may also be carrying customer Wi‑Fi, music streaming, phones, cameras, and the ordering system. Those should be separated with proper network configuration, and the internet service and equipment need enough capacity for all of them. Given the size of the restaurant and the business impact, getting a qualified network technician to survey and configure the system is probably the safest fix instead of continuing to add consumer routers.
Since the handhelds look connected but stop working, the issue may not be Wi‑Fi coverage alone. Check whether they are receiving valid IP addresses, whether DHCP leases are expiring, and whether the ordering system itself is reachable. Also look for wireless interference or overloaded access points. Wired computers would not reveal a wireless problem, so testing a laptop or handheld in different areas of the building could help identify dead zones or roaming issues.
The first thing to clarify is whether these are truly multiple routers or just wireless access points or mesh nodes. A normal setup should have one main router handling DHCP and routing, with switches and properly configured access points extending coverage. If every device is acting as a router and handing out its own IP addresses, they can interfere with one another and cause intermittent connectivity. The extra units should usually be placed in access-point or bridge mode, or replaced with a properly managed mesh system.
For a restaurant this size, using several access points is completely reasonable; using several independent routers on one network is the problem. The access points should ideally be wired back to the main network, use coordinated channels and appropriate power levels, and broadcast the same network if seamless roaming is needed. A network installer or IT technician should configure it rather than relying on default settings.
I’m going to check the exact models and settings at work so I can tell whether they’re routers, access points, or extenders.
