Sadly no, the best thing you can do to improve your Wi-Fi experience here is making sure you have a good router, not the one GCI gave you.

Figure out how much you are willing to spend and then buy the router at your price point:

$300: ASUS AX6000 WiFi 6 Gaming Router (RT-AX88U) - Dual Band Gigabit Wireless Router, 8 GB Ports, Gaming & Streaming, AiMesh Compatible, Included Lifetime Internet Security, Adaptive QoS, MU-MIMO https://www.amazon.com/dp/B07HM6KJN8/ref=cm_sw_r_cp_api_glt_i_Z1H573VBJEAWK3MX0C8Z

$110: TP-Link WiFi 6 AX3000 Smart WiFi Router (Archer AX50) – 802.11ax Router, Gigabit Router, Dual Band, OFDMA, MU-MIMO, Parental Controls, Built-in HomeCare,Works with Alexa https://www.amazon.com/dp/B07YMFZ28Q/ref=cm_sw_r_cp_api_glt_i_NJV99DD4MXBJ9QHQY6G1

$80: TP-Link WiFi 6 Router AX1800 Smart WiFi Router (Archer AX20) – 802.11ax Router, Dual Band Gigabit Router, Parental Controls, Long Range Coverage https://www.amazon.com/dp/B085288G3M/ref=cm_sw_r_cp_api_glt_i_7EXWQMKGZ5B445FPRV1R

$50: Limited-time deal: TP-Link AC1750 Smart WiFi Router (Archer A7) -Dual Band Gigabit Wireless Internet Router for Home, Works with Alexa, VPN Server, Parental Control, QoS https://www.amazon.com/dp/B079JD7F7G/ref=cm_sw_r_cp_api_glt_i_dl_CV539G50007HYWBTAPYA

I would recommend the TP-Link WiFi 6 Router AX1800. I currently use it and it has very fast speeds, great range, and several features include QoS and WPA3.

EDIT: However, if your main concern is range, I would recommend a mesh wifi system like the eero mesh WiFi system.
