LG U+ slow internet in South Korea: tests, evidence and complaints

If your LG U+ connection is slow or unreliable, start with these equipment checks. Then document a repeatable result and ask for a specific investigation.

Applies to: Paths checked in LG U+’s own manuals for the GAPK-8100 (2025) and GAPD-7500R (2024); the GAPM-7500R manual shows the same menus as the GAPD-7500R. Mesh steps are from the MAPK-1000 manual. The GAPK-8100 has a 6 GHz band and an MLO network that the 7500R models lack.Checked: 3 November 2026

When this helps

  • You use LG U+ in South Korea.

Check your U+ 와이파이 공유기

These checks apply to U+ 와이파이 공유기. Check the model before following its menus.

  1. Sign in and open 상태정보 › 인터넷 연결 정보 (Internet connection information). It refreshes every ten seconds.

  2. It shows the connection state, external IP address, gateway, DNS servers and Wi-Fi channels.

  3. 상태정보 › 네트워크 통계 (Network statistics) shows traffic and errors for each port.

  4. 상태정보 › 시스템 로그 (System log) lists events. Click 로그 저장 (Save log) to keep a copy.

Separate the service from your home Wi-Fi

For the exact settings and supported equipment, see the U+ 와이파이 공유기 guide.

Do not factory-reset the equipment as a first step. A reset can erase service settings and interrupt phone service.

  1. Compare a wired connection to the router with Wi-Fi on the same device.

  2. Repeat the same test server during the slowdown and at a quieter time.

  3. Record download, upload, latency and whether another household device was using the connection.

How to complain to LG U+

Use LG U+’s official support to report the fault. Request a formal complaint reference if it remains unresolved.

Include the plan wording, dates, test conditions, previous references and the specific outcome you want. Ask for a written response.

Check the complaints procedure in your South Korea service contract before escalating. Use the national regulator’s consumer guidance for your service.
