Network name examples:
Depends on your LAN configuration, for example:
# ping vim4-05690 PING vim4-05690 (192.168.30.203) 56(84) bytes of data. 64 bytes from 192.168.30.203 (192.168.30.203): icmp_seq=1 ttl=64 time=37.3 ms # ping -c1 vim4-05690.local PING vim4-05690.local (192.168.30.203) 56(84) bytes of data. 64 bytes from 192.168.30.203 (192.168.30.203): icmp_seq=1 ttl=64 time=37.3 ms # curl http://vim4-05690.local # curl http://192.168.30.203 # curl 192.168.30.203 # ssh root@vim4-05690 # ssh root@vim4-05690.local
Ethernet works automatically; just plug in an ethernet cable from your router.
User can setup and configure a WLAN connection Network → Wi-Fi → Wi-Fi Select Connection.
In cases wherein you are unable to configure a WLAN or LAN connection locally on your device, you can share your internet connection from a mobile device (e.g. smartphone) to your single board computer using the Easy Wi-Fi mode.
You can enable the Easy Wi-Fi mode on your device in two ways:
Setup a new hotspot from your mobile device with the following configuration:
Once OOWOW is in the Easy Wi-Fi mode, it will automatically scan and connect to your Wi-Fi hotspot generated by your mobile device.
You can enable the OOWOW hotspot feature in two ways:
The OOWOW hotspot will have the following configuration:
These hostnames can be used for device access via the hotspot:
Tip: For security reasons, you need to manually accept incoming hotspot connections by short pressing the POWER button once.
Network → Hotspot → Hotspot QR code.
Connect your device directly to your computer using a USB cable. This feature will interest developers or advanced users; there is only a peer-to-peer network connection, no internet packets will be forwarded to your device.

The process of new OS Installation is the biggest headache for users of single board computers (SBC); before installing an OS, users must read tons of manuals, trawl through online forums, learn how to install/reinstall using their desktop/laptop PC, learn where to find proper images etc…If something goes wrong it is possible to “BRICK” (destroy) your device(even through we can use TST mode to recovery rhe device).
In other words, any form of device upgrade, maintenance, or OS reinstallation requires advanced skills and external hardware, and this is out of reach for the average user, or users in regions without desktop/laptop PCs. With OOWOW your SBC becomes a standalone device; perform all maintenance functions and OS installation directly from the device itself.
OOWOW understands the end user deeply; it provides an out-of the-box, universal OS delivery and device configuration solution for all SBCs in the market today and into the future.
Live life easily with OOWOW!
oowow - infinity level wow (will be a new 77th word in the English dictionary).
