Business Internet Provider in Roswell, GA: Managed Connectivity from COMNEXIA

COMNEXIA has been headquartered in Roswell, Georgia since 1991, and for 35 years we have sourced, configured, and managed business internet connections for Fulton County companies ranging from professional services firms to franchised auto dealerships along GA-400 and the Alpharetta corridor. We are not a carrier reseller that hands you a router and a trouble-ticket number. We act as your network architect and single point of accountability, selecting the right circuit type, configuring QoS policies, and monitoring uptime around the clock through our RMM platform, NinjaOne.

Why "Business Internet Provider" Means More Than Picking a Circuit

A raw internet circuit from a carrier delivers bandwidth. What it does not deliver is failover logic, traffic prioritization, security filtering, or any guarantee that your VoIP calls, cloud-hosted DMS, or credit-application portals will perform consistently under load. COMNEXIA closes that gap. We procure primary and secondary circuits, configure SD-WAN failover so that a carrier outage triggers an automatic sub-second switchover, and apply per-application QoS rules that give Microsoft Teams Phone and SIP trunking traffic precedence over general browsing. That matters specifically for dealerships running Dealertrack's F&I platform or Reynolds and Reynolds ERA, where a dropped connection mid-deal creates compliance documentation gaps and customer experience failures.

What COMNEXIA Delivers as Your Internet Provider in Metro Atlanta

• Circuit procurement and negotiation: We identify primary fiber options available at your Roswell or North Fulton address, compare SLAs across carriers, and handle the order and provisioning process on your behalf.
• SD-WAN with automatic failover: We deploy SD-WAN appliances that bond primary fiber with a secondary circuit (LTE/5G or a second fiber provider), set health-check intervals at the interface level, and route failover traffic without manual intervention.
• QoS configuration on LAN and WAN: We classify RTP streams for Microsoft Teams Phone and hosted PBX trunks, assign DSCP markings (EF for voice, AF41 for video), and enforce bandwidth policies per VLAN so that a software update or backup job cannot saturate a circuit during business hours.
• Firewall and DNS security layer: Every managed internet connection is placed behind a next-generation firewall with geo-blocking, IDS/IPS, and DNS-layer filtering. This directly supports the FTC Safeguards Rule requirement for dealerships to implement technical safeguards protecting nonpublic personal information transmitted over dealership networks.
• 24/7 uptime monitoring via NinjaOne: Our NinjaOne RMM agents monitor interface status, latency, and packet loss on managed routers and switches. Alerts fire to our help desk ticketing system within minutes of a degradation event, not after your staff calls in to report slow performance.
• Monthly reporting: Each month you receive a report showing circuit uptime percentage, failover events triggered, bandwidth utilization peaks, and any security events flagged at the network perimeter.

Dealership-Specific Connectivity Requirements

Auto dealerships in the Roswell and greater Atlanta market operate CDK Global Drive, Reynolds and Reynolds ERA, and Dealertrack on connections that must stay live during sales, F&I closings, and DMV transactions. CDK Global's hosted DMS model requires stable, low-latency internet with consistent DNS resolution. A circuit outage does not pause these workflows; it stops them and can create incomplete deal jacket records. COMNEXIA builds redundant internet designs specifically for dealerships, including separate VLANs for DMS traffic, guest Wi-Fi, and IP security cameras, with QoS policies that protect DMS and VoIP traffic even when the service lane is streaming diagnostic data from scan tools. Our configurations also address the FTC Safeguards Rule's requirement for access controls and encrypted transmission of customer financial data, a regulatory obligation that applies to every licensed dealership in Georgia.

How Onboarding Works

COMNEXIA follows a documented onboarding process. We start with a site survey that records existing circuit types, router hardware, switch topology, and current firewall rules. We produce a written network diagram and a gap analysis before touching any configuration. Circuit procurement runs in parallel so there is no delay waiting on carrier provisioning. SD-WAN and firewall configuration is staged and tested before cutover. Endpoint agents (NinjaOne) are deployed to routers and managed switches where supported, and your team receives a documented runbook covering failover behavior and escalation contacts. The entire process is tracked in our help desk ticketing system so nothing falls through.
