Fix a 5G home internet that drops

We'll check signal strength, gateway placement, band selection, and power—so the 5G connection stops dropping or we tell you when to call your provider.

Steps

Goal: Check power, signal strength, and placement so the 5G connection stops dropping.

  • Confirm the 5G gateway has stable power and ventilation. Overheating causes drops.
  • Log into the gateway admin and check RSRP and SINR. Weak signal (RSRP below -110 dBm, SINR below 5 dB) causes drops.
  • Move the gateway near a window, higher up, and away from obstructions. Retest signal.
  • Power-cycle the gateway and router.
  • Good: The connection stays up. Bad: The connection still drops—try band selection or call your provider.

Check signal strength

Goal: Confirm RSRP and SINR in the gateway admin.

  • Log into the gateway admin (often 192.168.1.1 or 192.168.12.1—check the sticker on the gateway).
  • Look for RSRP (signal strength) and SINR (signal quality). RSRP below -110 dBm or SINR below 5 dB often causes drops.
  • Good: RSRP above -110 dBm, SINR above 5 dB. Bad: Weak—improve placement or call provider.

Placement

Goal: Improve signal by moving the gateway.

  • Place the gateway near a window facing the tower direction. Higher placement (shelf, wall mount) often helps.
  • Avoid metal, thick walls, and appliances that block or reflect signal.
  • Good: RSRP and SINR improve after moving. Bad: Signal stays weak—call your provider; tower coverage may be limited.

Power-cycle and band

Goal: Restart the gateway and try band selection.

  • Unplug the gateway for 60 seconds, then the router if separate. Plug the gateway in first, wait for it to acquire signal, then plug in the router.
  • If the gateway has band selection in the admin, try locking to the stronger band (e.g. n71 for range, n41 for speed).
  • Good: Connection stabilizes. Bad: Still drops—call your provider with RSRP, SINR, and steps tried.

When to get help

Call your 5G provider if:

  • The connection still drops after checking power, signal, placement, and band selection.
  • RSRP stays below -110 dBm or SINR stays below 5 dB after improving placement.
  • They can check tower coverage and line quality. Have RSRP, SINR, placement, and steps tried ready.

Verification

  • The 5G connection stays up for extended periods.
  • RSRP is above -110 dBm and SINR is above 5 dB in the gateway admin.
  • No repeated disconnects or reconnects.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Check power and heat Stable outlet, gateway has ventilation.
  2. Check signal strength Log into gateway admin; note RSRP and SINR.
  3. Improve placement Move gateway near window, higher up, away from obstructions.
  4. Power-cycle and band Restart gateway and router; try different band if available.
  5. Call provider Provider can check tower coverage; have RSRP, SINR, and steps tried ready.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • Gateway model
  • RSRP and SINR from gateway admin
  • Gateway placement (window, floor, obstacles)
  • When drops occur (pattern)
  • Steps already tried

Does the gateway have stable power and ventilation?

Unstable power or overheating causes drops.

Check the gateway is on a stable outlet and has ventilation. Good: power stable, gateway cool. Bad: unstable power or overheating—fix first.

Yes No

You can change your answer later.

Fix power and ventilation

Use a stable outlet. Move the gateway to a cool, ventilated spot. Check if drops stop.

Done

Is RSRP above -110 dBm and SINR above 5 dB?

Log into the gateway admin. Check RSRP and SINR. Weak signal causes drops.

Log into the gateway admin (IP on sticker). Check RSRP and SINR. Good: RSRP above -110 dBm, SINR above 5 dB. Bad: weak signal—improve placement.

Yes No

You can change your answer later.

Improve placement

Move the 5G gateway near a window, higher up, away from metal and thick walls. Retest signal. If still weak, call your provider.

Done

Power-cycle gateway and router

Unplug gateway 60 seconds, then router. Plug gateway in first, wait for signal, then router. Good: connection stable. Bad: still drops—try band selection or call provider.

Yes No

You can change your answer later.

Connection stable

The 5G connection stays up. Monitor for further drops.

Done

Try band selection or call provider

If the gateway has band selection, try locking to the stronger band. If still drops, call your provider with RSRP, SINR, and steps tried.

Done
