About GCI

GCI is Alaska's largest and most capable ISP — fiber and DOCSIS cable in Anchorage, Fairbanks, and Juneau; fixed wireless and satellite in remote communities. Fiber plans reach 2 Gbps; rural Alaska options are limited to 25–100 Mbps.

Technologies GCI uses

  • Fiber (FTTH)
  • Cable
  • Fixed Wireless

GCI plans are asymmetric, meaning upload speed is significantly lower than download — factor this into plans if you work from home, stream, or back up to the cloud.

How to get an honest GCI test result

  • Test on a wired Ethernet connection — Wi-Fi alone can hide 10–30% of your real line speed
  • Run one test mid-morning and one between 7–10 PM local time — the gap exposes peak-hour congestion on the GCI segment
  • Watch ping and jitter, not just download — they determine whether calls, games, and cloud apps feel responsive
  • Run 3–5 tests back-to-back and use the minimum — that is the speed your real-time apps experience, not the marketing peak
  • If your wired test is consistently 20%+ below the plan, it is worth a support call to GCI — provisioning drift is real and they will usually refresh your modem remotely

Frequently Asked Questions

What speeds does GCI deliver in United States?

GCI typically delivers 25–2000 Mbps in United States across its Fiber (FTTH), Cable, Fixed Wireless plans. Run a wired Ethernet speed test to see what your specific line is producing right now.

Why is my GCI speed test slower than my plan?

The three most common causes are Wi-Fi (can hide 10–30% of real line speed), peak-hour congestion between 7–10 PM on shared segments, and outdated router or modem hardware. Run one test on Ethernet mid-morning and a second at 9 PM to see the gap.

Is GCI good for gaming and video calls?

GCI plans have asymmetric upload, which can affect video calls and cloud uploads — check your upload number and ping, not just download. For competitive gaming, aim for ping under 30 ms and jitter under 5 ms on a wired connection.

How do I run an accurate GCI speed test?

Connect your device to the router via Ethernet cable, pause downloads and cloud sync, close streaming apps, and run 3–5 consecutive tests. Record the minimum result — that is the number that matches real-time usage, not the peak.
