Network Diagnostics
Restoring Your Broadband Connection
Experiencing buffering during video streaming or losing connection during remote work? Before scheduling an on-site technician visit or waiting on hold, run through these standardized self-diagnostic tests.
Outage Check Tip
If all lights on your modem go dark or flash simultaneously, check your mobile smartphone over cellular data to verify whether a localized neighborhood outage has occurred.
1. The Standard 60-Second Power Cycle
More than 70% of residential network connection problems are solved by flushing temporary memory buffers in your modem gateway:
- Disconnect Power: Unplug the AC electrical cord from the back of your modem/router gateway. Do not just press the power button; fully disconnect electrical power.
- Inspect Coaxial Cabling: Ensure the cylindrical coaxial cable connector is screwed finger-tight to both the wall outlet and the modem input jack. A loose connector introduces signal noise.
- Wait a Full 60 Seconds: Allow internal capacitors and routing caches to completely clear.
- Reconnect & Monitor Status Lights: Plug the power adapter back in. Wait 3 to 5 minutes as the unit boots. Look for solid green or white lights on Power, DS/US (Downstream/Upstream), and Online.
Deciphering Hardware Lights
What Your Modem Indicator Lights Mean
The front LED lights on your gateway communicate its communication status with the telecommunications headend.
Online Light Solid
Your modem has locked onto broadband frequencies and established an authorized internet IP session. If devices still cannot browse, the issue is internal Wi-Fi routing.
DS/US Blinking
The gateway is searching for downstream or upstream carrier channels. This indicates degraded coaxial signal, an external street cable fault, or an active regional outage.
No Internet / Error
The device cannot reach the authentication server. Verify whether your account has an administrative hold or billing interruption before requesting hardware replacement.
WLAN Active
The wireless local area network is broadcasting 2.4GHz and 5GHz radio frequencies. Devices can connect locally even if WAN internet connectivity is down.
Performance Optimization
Fixing Slow Wi-Fi Speeds in Your Home
If your internet works but provides speeds significantly lower than your subscribed speed tier, examine these common environmental bottlenecks:
Connect smart TVs, gaming consoles, and work laptops to the 5 GHz Wi-Fi band for maximum throughput. Reserve the 2.4 GHz band for smart home appliances requiring long-range reach through walls.
Place your gateway in a central, elevated position off the floor. Avoid placing equipment inside enclosed cabinets, behind large televisions, or near metal appliances and microwave ovens.
