Our modem has just gone on a blink.
G5 tower Alcatel touch Pro four ports.
Closest machine works on ports 1,2,4. Other machines in the house will not work at all on any port even if by themselves. No two machines can work at one time.
This is after a spike  Today Tuesday.
Modem and machines protected by guards
