# [From QnA] WIZ105SR - Justin Grodin

## Question

Asked by jameskim on 2013-09-09 in Serial-to-Ethernet & ConfigTool.

## This post came from QnA of WIZnet website

I have 20 units, 5 of them are timing out on my control software. They are all configured exactly the same. The only noticeable difference is when using the configuration utility, the dialog box in the top right corner says “connected” on the units that time out. On the units that work, it says “not connected”.

I have read through the manual and there is no reference to this dialog box or what the “connected” vs. “not connected” status actually means. Please help!
