So,

we installed the repeater a while ago and it always had this issue.

It just restarts every so often, gone for like a minute and then back. Really annoying when you try to game or watch youtube and then the connection is just gone. 

I didn't find any setting in the Tether app (unless I missed it) so I am just gonna guess this is unintended. 

How can I fix this problem? If it is a software problem, how can I update that? 

Thanks!
