Well, a few months back, my internet at random would drop out, and not come back online until the router was reset.
Then my home server (old desktop) started dropping out 2 HDD’s (out of 6) at random times and they would not come back until a reset.
Solutions :
Router : Replaced. Been no dropouts etc since.
Server : Having a 350W PSU running 6 spinning discs apparently is not healthy. Replaced with 600W, no more drop outs.
The old router was a Fritzbox I got 2nd hand a few years back, good little unit until the dropouts started, and I noticed the UI was getting extremely slow. Replaced with a Grandstream unit – and wow, UI is so fast. Impressed.
The PSU, I honestly thought was a 450W, so didn’t really consider that as being the problem for the server, thought it might be the RAID card I was using….. until I actually stripped the PSU out. Oops…. 350W. Now has a DeepCool 600W and no more HDD vanishing acts.
