Have to power reset too often

If you are going to give it more time you should closely investigate how the unit works. It is not clear how much information you have. If you have a “glitch” what symptoms does that include? Do clients not have WIFI or is/are the cellular signal(s) down? Some people misinterpret what is actually taking place. I am assuming you are referring to the mobile application. I found the mobile app to be a bit flakey. I am sitting here typing this, I launch the mobile app on my iPhone and NADA it can’t figure it out. I find that to be a common issue with the mobile application. Some seem to like it but I am not sure how much value it adds. You can get the cellular metrics info from it if it works and post your signal characteristics. If you have 4-5 bars on the gateway and good proximity to a cellular tower then the “glitching” might be related to the tower. The actual cellular metrics help understand how strong and clean the cellular signals are. Using cellmapper.net to locate the tower(s) with the PCI informations from the gateway will possibly help locate the gateway a little better. If there is excessive noise impacting the cellular signals that will lead to poor performance. The more information you share the better the responses will be from the community. 

It is necessary, of course, to get the gateway in the best location but also avoid the obstacles that impair the signals. The cellular solution demands more effort, and focus with respect to the environment than a cable solution. It becomes a balancing act to distribute WIFI and get the best cell signals. If you have questions or more information feel free to post.
