"The internet is slow" is the complaint we hear most from new clients. Most of the time the internet connection itself is fine. The problem is the Wi-Fi between the router and the staff's laptops. Here's what usually goes wrong, and how we design networks that stay stable all day.
Why the ISP router isn't enough
The modem-router your internet provider installs is built to connect one household. In a business it's usually placed wherever the fiber enters the building, often a corner or back room, and it's asked to serve dozens of devices, CCTV, phones, and guests through concrete walls. It also tends to keep its default admin password. Treat it as a modem, and let proper business equipment handle Wi-Fi and security.
Plan coverage with access points, not boosters
Range extenders and cheap boosters often make things worse: they repeat a weak signal and cut speed in half. The reliable approach is multiple access points mounted on ceilings, each connected back to a network switch by an Ethernet cable, all managed as one network.
- Plan for capacity, not just coverage: a meeting room or call-center floor needs more access points than a hallway
- Mount access points high and central, away from metal cabinets and thick concrete columns
- Wire them back with Ethernet wherever possible; use mesh only where cabling truly isn't practical
- Use a site survey to find dead zones before installing, not after
Wire what doesn't move
Desktop computers, printers, POS terminals, VoIP phones, and servers should be plugged in with a cable. Wired connections are faster, more stable, and free up Wi-Fi capacity for laptops and phones. For a BPO or any team on calls all day, wired desks are the single biggest improvement in call quality.
Separate networks for staff, guests, and devices
One shared Wi-Fi password for everyone is both slow and unsafe. Set up at least:
- Staff network with access to files and printers, using a strong password or individual logins.
- Guest network that only reaches the internet, with bandwidth limits so guests can't slow down operations. Essential for clinics, hotels, cafés, and waiting areas.
- Device network for CCTV, smart TVs, and other devices that are rarely updated and shouldn't sit next to your accounting computer.
Settings that stop dropped calls
- Prefer the 5 GHz (and 6 GHz where supported) bands for laptops; 2.4 GHz is crowded and slow
- Set channels so neighboring access points don't interfere with each other or with nearby offices
- Enable quality of service (QoS) rules that prioritize voice and video traffic
- Keep firmware on access points and firewalls updated
Plan for the internet going down
Outages happen. A business firewall can combine two connections from different providers, such as fiber plus a second fiber line or a 5G backup, and switch between them automatically. For a retailer or BPO, an hour offline costs far more than the second connection. Pair it with a UPS on your network equipment so a brownout doesn't reset everything.
