1. Audio Output – There is no sound from the internal speaker although the headphone jack works; the electrical connection is fine.
2. Wifi – No wifi Access Points are shown in the wifi dialogue, therefore wifi does not operate. Initially 5Ghz networks were absent, then it would not connect to any wifi signals, now no signals are shown.
3. Build Quality – Upon opening the device to diagnose the speaker problem I found that there is a stray fine copper wire from under the main board to the screen hinge (with hindsight this could be a shard from the heatsink, I didn't remove the main board from the case to look).
Regarding the Wifi problem, if there is no wifi Access Points, it maybe lack of corresponding frequency band. We suggest you to find out the GPD WIN wifi patch as shown below:

Regarding the problem of internal speaker, please try to see if there is any sound after restarting the device.
