Common Internet Issues and Solutions

Internet Outage


You’re staring at a blank screen, realizing you can’t access anything online.


  1. Check for Outages: Head to the Xfinity Status Center to confirm if there’s a regional outage impacting your service. It’s also worth checking the Xfinity My Account app for real-time updates.
  2. Restart Your Gear: Unplug your modem and router, count to 30 (or maybe take a deep breath), and plug them back in. Sometimes, a little reset is all it takes.
  3. Inspect Those Cables: Ensure all cables are snugly connected—loose cables can be sneaky culprits of downtime.
  4. Survey Your Splitters: If you’ve got splitters in the mix, ensure they’re up to snuff. Faulty splitters can wreak havoc on your signal strength.
  5. Reach Out for Help: If the issue persists, don’t hesitate to ring up Xfinity support. They’ve got the know-how and may dispatch a technician to save the day.

Slow Internet Speed


Web pages loading slowly, buffering videos, slow downloads.


  1. Run a Speed Test: Fire up the Xfinity Speed Test to gauge your current speeds. Compare them against what you’re paying for.
  2. Optimize Your Wi-Fi: Move that router to a prime spot—center stage, away from metal and other electronic interlopers.
  3. Update Firmware: Ensure your modem/router firmware is up to date.
  4. Limit Bandwidth Usage: Disconnect unused devices and avoid high-bandwidth activities simultaneously.
  5. Change DNS Settings: Sometimes, changing DNS settings to a public DNS server like Google DNS can improve speed.
  6. Check Data Cap: Ensure you are not exceeding your data cap, which can throttle speeds.

Don’t let slow internet or unreliable connections hold you back. Switch to Xfinity for top-tier performance across all your devices. Our team is ready to assist you with the upgrade process. Dial +1 (518) 594-1937 and transform your home experience!
