Hello ssekim, I tried your steps but i have this error ATI2 WizFi210 1.1.0.5(W) [OK] AT+NSTAT=?

Pinging however works fine. Any solutions?

I think that there are some mistyping or something like that in your test. Generally, “[ERROR: INVALID INPUT]” means wrong-format-parameter as below. [quote]at+nctcp=4.4.4.4,77 [ERROR] at+nctcp=4.4.4.4, [ERROR: INVALID INPUT] [/quote]

I keep getting spam report issue, and do not let me reply. I was wondering if this is common on the firmware. Since only this command has ‘INVALID INPUT’ I tried with different software terminals and parameters, all other commands work fine. Any other solution for this issue?

What is your F/W version? How about try it again with latest F/W version? You can download that in the below link. [url]http://wizwiki.net/wiki/doku.php?id=products:wizfi250:wizfi250firmware:start[/url]
