Wi-Fi that drops, a network that slows to a crawl every afternoon, printers that disappear, phones that cut out — most network problems have a specific, findable cause. Harold Ragan Communications troubleshoots existing business networks across Northwest Arkansas, whoever installed them, and fixes the cause instead of rebooting the router and hoping.
We can. Eleven years as an IT director and a decade running a managed-services shop means most of these problems are familiar.
Coverage gaps, channel interference, too many or too few access points, or devices sticking to a distant AP.
Switching loops, a failing switch, duplex mismatches, saturated uplinks or one device flooding the network.
IP address conflicts, DHCP pools running out, or printers and cameras on addresses that keep changing.
Jitter and packet loss from congestion, bad cabling or missing traffic priority for voice.
Damaged runs, bad terminations and cables that only pass 100 Mbps — found by testing each drop.
A router or controller nobody can log into, or a network a previous vendor set up and never documented.
We start by listening: when does it happen, who is affected, what changed. Then we look at the network from the bottom up — physical cabling and connections, switches and how they are linked, IP addressing and DHCP, the gateway and firewall, and finally the Wi-Fi: where the access points are, what channels they are using and what interference is in the air.
Often the fix is simple once found — a bad patch cable, a looped switch, a DHCP scope that is too small. Sometimes it points to a bigger issue such as cabling that needs to be replaced or a Wi-Fi layout that was never designed for the building. Either way, you get a plain-English explanation of what was wrong and what we did, and a recommendation if more work makes sense.
Warehouses are hard on Wi-Fi: high ceilings, metal racking, and inventory that changes the RF environment as shelves fill and empty. The fix is usually properly placed, hard-wired access points with directional or high-ceiling-rated antennas where needed, and channels planned for the space — not a stronger router. See commercial Wi-Fi design.
Call or send the form — what is happening, when, and what equipment you have.
We test cabling, switching, addressing, the gateway and Wi-Fi to find the cause.
Simple fixes happen on the spot. Larger work gets a fixed quote before we do it.
You get a clear summary of what we found, what we changed and any recommendations.
Offices, restaurants, retail, clinics, churches and warehouses throughout the NWA metro.
Yes. Most troubleshooting calls are for networks someone else built. We work with common business equipment including UniFi, and we document what we find.
Some configuration issues can be handled remotely once we have access, but most network problems are best diagnosed on-site, where we can test cabling and Wi-Fi in the actual building.
Common causes are more devices connecting than the access points were designed for, channel interference, or one device consuming bandwidth. Diagnosis tells us which.
Yes, if you want it. After we stabilize a network we can stay on as your network contact for future changes and problems.
