Need help with your MK802 Android Mini PC?

If you are facing a problem with your Rikomagic MK802 Android Mini PC, this troubleshooting guide is for you. I have written four articles on the MK802 so far covering the many functionality and versatility of the MK802 but to get the most out of this great little gadget, you do need to jump through some hoops.

I have gotten many requests for help and I have also scoured the web for answers to my own questions. I thought that it might be a good idea to compile all that I have learned into a single troubleshooting guide that MK802 users can refer to.

Answers will be given for the simpler questions and for more complex answers this guide will point you to the right resources. This is by no means a complete guide and I hope to grow it with your contribution as well.

My MK802 has problems connecting to my WiFi router

Problem: My MK802 cannot connect to their wireless router even though the signal is very strong or the MK802 is located right next to the router. MK802 displays a "WiFi is not in range" error message. When my MK802 is switched on, it prevents my other WiFi devices from connecting to my router.

While not everyone faces this problem but the occurrence seems to be quite high. One possible explanation given is that the HDMI port or cable on the MK802 is generating high RF interference which disrupts the router's WiFi signal.

One suggested way to resolve this is to unplug the HDMI cable from the TV and let the MK802 connect to WiFi before reconnecting the HDMI signal. Once the WiFi connection has been established, it is easier for it to maintain the signal.

Another suggested method is to put ferrite beads on the HDMI cable to reduce the interference.

Another possible cause which I personally discovered is that there might be interference from other 2.4 GHz RF devices like wireless keyboard, wireless mouse or even cordless phone. Try switching off the other devices to see if they are causing problems to the MK802's WiFi connectivity.

According to the specification of the new MK802 II, it has a newly redesigned ESD circuitry protects and eliminates ESD problems. This is a good indication that the manufacturer is aware of the problem and has implemented a fix in the new version. On the other hand, there are MK802 II users who complain of this issue as well so the problem may not be entirely resolved.

On the Miniand Forums (Miniand is one of the resellers of the MK802), Miniand claims that it is a hardware defect and the MK802 should be returned for warranty replacement.

Reduce RF interference by using ferrite cores

Try a ferrite core around the HDMI cable to cut down on the interference to the WiFi signal.

The WiFi connection on my MK802 is very slow

Problem: The WiFi connection on the MK802 slows to a crawl when accessing the internet.

This problem is related to the WiFi connection problem. The HDMI is possibly generating high RF interference that disrupts the router's WiFi signal. For more details, please refer to the WiFi connection problem.

Does the MK802 support wired LAN?

Problem: Can I use a wired network connection? How can I connect my MK802 using wired Ethernet LAN?

The MK802 can be connected to a wired Ethernet LAN connection by using a USB Ethernet adapter. The StarTech.com Compact Black USB 2.0 to 10/100 Mbps Ethernet Network Adapter (USB2106S) has been found to work with the MK802. Just connect it to the USB port and then plug your LAN line to the adapter.
