Cox vs Quantum Fiber vs Starlink in Las Vegas

8 min read Updated 2026 Las Vegas, NV

The Short Answer

If you want the simplest setup with the widest availability, start with Cox. If Quantum Fiber is available at your address, it's worth serious consideration for the fiber speeds and price predictability. Starlink is the best backup or primary option where wired service is poor or unavailable.

Cox Communications

Cox is the dominant cable internet provider in Las Vegas. Their infrastructure covers most of the valley — Las Vegas, Henderson, Summerlin, North Las Vegas, Spring Valley, and beyond.

Pros

  • Widest coverage across Clark County — most likely available at your address
  • Reliable performance for most households
  • Multiple plan tiers (100 Mbps to 2 Gbps)
  • Local customer service and technician availability

Cons

  • Cable technology means shared bandwidth during peak hours
  • Price increases after promotional periods end
  • Upload speeds significantly slower than download on most plans
  • Data caps on lower-tier plans

Quantum Fiber

Quantum Fiber (formerly CenturyLink) offers fiber internet where available. Fiber coverage in Las Vegas is expanding but not yet valley-wide — check quantum.com for your specific address before assuming availability.

Pros

  • Symmetric speeds (upload = download) — great for remote work and video calls
  • More predictable pricing — no data caps on most plans
  • Fiber is more reliable than cable technology long-term

Cons

  • Not available everywhere — check your address first
  • Fewer plan tiers than Cox

Starlink

SpaceX Starlink provides satellite internet to all of Clark County — useful where wired options are limited or unavailable.

Pros

  • Available anywhere in Clark County — no address check needed
  • No long-term contract required
  • Improving speeds and reliability as more satellites launch

Cons

  • Higher latency (20-60ms) than wired — noticeable in gaming and video calls
  • Equipment cost ($499 for the dish)
  • Performance can degrade in severe weather
  • Typically more expensive per month than comparable wired plans

Recommendation by Use Case

  • Remote workers / video calls: Quantum Fiber if available, then Cox Gigablast
  • Gamers: Cox or Quantum Fiber — Starlink latency is too high for competitive gaming
  • Streaming households: Any provider at 100+ Mbps works fine
  • Areas with poor Cox service: Quantum Fiber or Starlink
  • New construction / rural edges of valley: Starlink until wired options expand
