Internet conection drops out

[news]

[wireless]

I have a desktop PC hardwired to a telus modem T3200M and 6-7 laptops/cellphones/printer connected to the same modem through a 2.4g and 5g WiFi.
Time after time the connection to internet is lost either on my PC or from other devices connected through WIFi.
Browser and computer settings seems to be OK and a device restart does not solve the problem. The internet connection gets reestablished when I restart the modem. I think the problem is some kind IP conflicting issues.
Telus helpline could not see any problem with the connection. He offered to send me a new modem or set up a visit with a telus technician. Now before I swap modems or leave work for the technician, I want to know if this is a hardware (modem) issue or some network/modem configuration issues. Has anyone experienced smth similar?
Any suggestion before I get the technician to come and check it?
thanks
