Slow Internet Speed

1. Physical Connection Not Meeting Standards

• Insufficient cable specifications: aging cables, broken cores causing signal attenuation and negotiated speed reduction.
• Ethernet port hardware faults: oxidation, bent pins, or poor contact on Mini PC Ethernet port, router, or optical modem LAN ports causing unstable connections.

• Replace with qualified cables. If using a wired connection, confirm the cable specification. For gigabit (1000Mbps) networks, use Cat 5e (Category 5e) or Cat 6 (Category 6) or higher cables.

• Check Ethernet port status: inspect if pins are deformed, unplug and reconnect the network cable, or plug it into another network port, and observe if the port indicator light functions normally.

  The color of the Ethernet port light usually indicates the connection status and network activity: green indicates a high-speed connection (100 Mbps/1000 Mbps) or data activity; amber yellow indicates a lower speed (10/100 Mbps) or potential issues; red indicates an error; and no light indicates no connection.

   

2. Incorrect Port Configuration

• Optical modem/router port specification mismatch: mistakenly plugging the cable into a 100 Mbps LAN port instead of a gigabit LAN port; some optical modems only have one gigabit port, the rest are 100 Mbps ports.

• Confirm port specifications: plug the cable into the LAN port marked "1000M" on the optical modem/router.

   

3. Wired Network Card Driver Issues

• Outdated network card drivers causing underperformance and frequent packet loss.

• Visit the GEEKOM official support website Geekom, find the corresponding product model, download the original manufacturer's compatible network card driver, reinstall it, and restart the device after installation.

1. WiFi Frequency Band and Signal Quality Issues

• The PC's WiFi frequency band is incompatible with the currently connected router's band.
• Severe signal attenuation: Mini PC is too far from the router or there are load-bearing walls/metal obstructions causing very low signal strength.

• After connecting the PC to WiFi, open WiFi settings to check the actual bandwidth of the current connection.

• If the actual bandwidth is much lower than the theoretical bandwidth, it indicates that the PC's WiFi default frequency band is incompatible with the router's band. You can open Device Manager, right-click the PC's WiFi network card, select Properties, go to Advanced, change the current WiFi frequency band to the fastest band supported by the router (usually indicated on the router), and check if the network bandwidth changes and if the connection returns to normal.

• Optimize placement: place the Mini PC closer to the router, avoid load-bearing walls, metal cabinets, fish tanks, and other strong obstructions; adjust the router antenna direction, ensuring antennas are vertical to the ground.

   

2. Driver and Power Management Settings Issues

• Outdated or incompatible wireless network card drivers causing low WiFi negotiation speeds and frequent disconnections.

• Visit the GEEKOM official support website Geekom, find the corresponding product model, download the original manufacturer's compatible network card driver, reinstall it, and restart the device after installation.

   

3. Antenna Faults

• Poor antenna contact: Mini PC antenna is loose or detached, causing a significant drop in signal reception capability.

• Check antenna status: open the device and check if the built-in WiFi antenna's IPEX connector is firmly plugged in, whether the external antenna is damaged or placed correctly;

     1) WiFi Antenna Detached:

Antenna Connection Status	Corresponding WiFi Signal

     WiFi antennas typically use a snap-fit design. The snap mechanism can detach due to vibrations during disassembly/transport or loosening after repeated connecting/disconnecting. In most cases, it can be reattached without tools, but the operation must be extremely gentle.

• The end of the antenna cable is a small round connector (U.FL/IPEX connector) that connects to the corresponding gold protruding socket (contact pin) on the WiFi card.
• Align vertically: Align the connector exactly above the socket (do not tilt! Tilting may cause damage).
• Press gently: Use the tip of tweezers or a finger to evenly press until a slight click sound is heard (indicating the snap is locked).
• Verify: Gently (horizontally) pull the cable. It should not easily come off (but do not pull hard!).
• If both antennas are detached, they should usually be reconnected to the correspondingly color-coded sockets — gray (AUX) / black (main line).

  2) WiFi Antenna Damage

A damaged antenna can only be resolved by purchasing a replacement. This antenna can be directly purchased on e-commerce platforms. Please note that WiFi antenna lengths vary among different GEEKOM models. For specific dimensions, please contact customer service.

3) Physical Damage to WiFi Antenna

      Root cause analysis: Due to mechanical compression from adjacent parts during assembly, the WiFi antenna becomes deformed (flattened).

      You can use tape to fix the antenna to prevent it from moving inside the case or shifting.

1. Insufficient Cooling Causing Hardware Throttling

• When the Mini PC runs under high load for a long time, the CPU, chipset, and network card temperature become too high, triggering thermal throttling, directly leading to significant network performance degradation, speed fluctuations, and lag.
• Dust accumulation on cooling fans and dried thermal paste further reduce cooling efficiency.

• Improve cooling: clean dust from the Mini PC's fan and vents, replace the CPU thermal paste; place the Mini PC in a well-ventilated area, avoid blocking vents; add a cooling base to assist cooling.

   

• Adjust BIOS cooling strategy: enter BIOS, set cooling strategy to "Performance Mode" to raise fan speed thresholds and prevent premature throttling.

  Step 1: When powering on or restarting, repeatedly press the Del/Delete key to enter the BIOS menu.

  Step 2: After entering the BIOS menu, navigate to the Advanced tab, find the PowerMode option, and change it to Performance Mode. Then press F4 to save settings. The system will restart automatically to apply the configuration. If this option is not under the Advanced tab, check the Main tab. If still not found, adjust FanMode instead.

2. Outdated BIOS version

• Outdated BIOS version with hardware compatibility bugs causing abnormal network card performance.

• Update BIOS version: visit the GEEKOM official support website Geekom, download the latest BIOS for your model, and follow official instructions to update.
