Hi, 1. Who is your SIM card carrier? if you use the same SIM card on another 4G device, is the internet stable? 2. When the problem happens, please send us screenshot of Advanced->Status page, Advanced->Network->Internet page along with the whole system log file.

Hi, do you mean only wireless connection loses internet, wired devices are always having internet access?

If so, please try to change WiFi channel and channel width on Advanced->Wireless->Wireless Settings page to see if the WiFi will be more stable.

 

By the way, may I know how many wireless client devices do you have in total? and will they lose internet access at the same time or just randomly devices lose internet at a time?
