METAL 2 SHPN WIFI KEEPS DISCONNECTING FROM COMPUTERS USING CONNECTING TO ITS WIFI.

GOOD DAY
I bought 951ui and metal 2 shpn for my two offices. I configured them as dchp client because i have dhcp server running on my cisco router already. Since then we have been enjoying good wireless browsing but today i discovered that every system connected to metal 2 wifi were disconnected and if connected again it still keeps disconnected. I have checked the router settings and there is nothing changed from my initial settings. So kindly help me on possible solution to this problem.

thanks and regards,
Noaha.
