Frequently Asked Questions

What Is Network Security?

Best network support companies in Chicago

CTI Technology provides network support for Chicago-area businesses with 20 to 250 employees, covering firewalls, switches, wireless, remote access, and connections between multiple offices. CTI has supported Chicagoland businesses since 2004, from its Elgin headquarters with staff in Chicago and Elgin. Network support is part of CTI’s managed IT plans, which run $200 to $400 per user per month and include 24/7 threat monitoring and incident response. Average help desk response and resolution times are both under one hour, and same-day onsite support is possible when a problem needs hands on equipment.

Office Wi-Fi keeps dropping, who can fix it?

Dropping Wi-Fi usually comes from too few access points for the space, interference, outdated equipment, or a network that has grown without a plan. CTI Technology starts with a wireless survey of your office to find dead spots and capacity limits, then fixes the layout, replaces aging equipment where needed, and monitors the network going forward.

What should a business plan for when setting up a new office network?

Plan the network before the move: internet service and a backup connection, cabling, firewall, switches, wireless coverage for the whole space, separate networks for guests and devices, phones, printers, and secure remote access. Order internet service early, since installation can take weeks. CTI Technology plans and installs office networks for Chicago-area businesses and coordinates with carriers and other vendors so the office works on day one.
