# Known Bugs List
The list below contains the most important problems in the firmware and their solutions.
It is an issue (opens new window) using WiFi and Windows to access the
.localhostname.Solution: Use a local ethernet connection to the electrolyser or IP address as a hostname.
DCN may assign an IP address to devices (computers, mobiles) connected to Wi-Fi AP associated with DCN enabled Enapter devices.
Solution:
- Delete the DCN from the Enapter Mobile App and create it one more time.
- If it is possible try to separate the DCN from your main network environment by connecting the DCN to another WiFi AP. It is no need to separate one DCN from another.
