Hi,How can I change the default IP. If connected to LAN and this IP is used yet from another device - I can not access the linkit.local host?

Hello, seems that it need a bit more in-depth debugging that we can do via comments.
Please contact techsupport@seeed.cc with your set up, the code you’re using, and any errors you might be getting.
Thanks.

it is"mylinkit.local"If you are still now able to ssh into it.. use network mapping tools to look for the ip address"who is on my wifi for windows"or nmap for a linux console. I have tried the static IP thing, beleive me.. in the long run, you wud not wan that, just stick with a host name.
