Intermittent packet loss and disconnects

Hi,

ive been experiencing intermittent packet loss and then eventually disconnecting on all devices on my network, ive been told many times to reset/reboot the hub i have and quite frankly if a piece of electronics requires that many resets to work its faulty.

i have a think broadband monitor setup from ages ago and you can clearly see large spikes 

i recently tried to get help through the webchat service to be told "they have sent strong signals to my hub so if i turn it off wait 10 mins and turn it back on it should be fixed" somehow they knew this would fix a tempermental issues, i said i didnt want to do it as ive had this same advise before.

i actually started believing that maybe the fault was my equipment so changed the switch i was using and requested a new coax cable from you to replace the old one ive had for years. and again it continues to happen

      i have a hub 4 and the network switch is not a problem as this issue was happening before the switch was installed and it happens on wifi too

  • Thanks for coming back to us AdamT3, I have looked into this on our system and can see that you have had a recent technician visit. Was the visit successful in resolving your connection issues?
