Signs Your Office Wi-Fi Needs Attention
- Video calls freeze or drop in certain rooms
- Wi-Fi slows down when the office is full
- You’re moving, expanding or remodeling an office
- You added a warehouse, shop floor or conference space
- Nobody is sure who set up the access points or what passwords they use
- Guests and staff share the same network
- Your cyber insurance questionnaire asks how your wireless network is secured
Common Causes of Slow or Dropping Wi-Fi
| Problem | Common cause | Typical fix |
|---|---|---|
| Dead spots in some rooms | Too few access points, or walls and metal blocking the signal | Add or move access points |
| Slow when the office is busy | Too many people on one access point, or an outdated internet connection | Spread the load across access points; review internet service |
| Calls drop when people walk around | Devices hold on to a far-away access point | Adjust access point settings so devices switch smoothly |
| Random disconnects | Old equipment or firmware that hasn’t been updated | Update or replace aging equipment |
| Security worries | Shared passwords, one network for guests and staff | Separate guest and staff networks, stronger encryption and access controls |

Frequently Asked Questions
Why does our office Wi-Fi keep dropping?
Common causes are too few access points, interference from neighboring networks or building materials, outdated equipment, and too many people on one access point. Most of these can be fixed by moving or adding access points and updating equipment.
Is Wi-Fi management included in CTI’s managed IT plan?
Yes. Managing your network, including Wi-Fi, is part of CTI’s flat-rate managed IT plan, priced at $200 to $400 per user per month. The exact price is confirmed in a written quote.
Should guests and employees use the same Wi-Fi network?
No. A separate guest network keeps visitors away from your company files, printers and systems. CTI sets up separate guest and staff networks as part of securing your Wi-Fi.
Which areas does CTI serve for Wi-Fi support?
CTI Technology serves businesses in downtown Chicago and all the Chicago suburbs from its headquarters in Elgin, Illinois.
