Wizfi630 connection refused

We have problem with wizfi630, when it is powered on for few days it sometimes stop working to send serial-ethernet by server. Our client software write connection refused. Web interface is working. When i make reset, it works.
We wanted to set automatic reset, but it does not work. it is set but not reseting.
We have firmware 1.1.28, is it repaired in newer firmware?
