Our NNis into BTW operate circa 25% of capacity of an evening (and 35% of a daytime). We have plenty of capacity.
Thanks for this. My daughter boyfriend was actually downloading heavily on his Xbox. She just told me this morning.
This is the reason for getting slower full fibre to half way.
Anyway case closed.
As around 6 people have already said, and when i saw the random spiking accross multiple mulitple isps, that either its the tp-link routers and or activities on your network.
When i saw that xbox/ps5 have automatic updates i suspected that.
I asked for you to check your dns servers, which are google's, and is fine (i wouldn't use them) but you get low dns latency via google. You don't see that in ping but effectivly "icmp latency" which is different.
QoS with a managed switch or a decent router, would lessen the spikes. But its pointless for 10 to 20 spikes in a day.
You can never completely remove random high lantency incidents. It pointless trying to and pointless worrying about it.
As others have said, fttp, g.fast, vdsl, adsl are all contended services that means all you need is a few heavy users maxing their connection to pull everyone else sharing that fibre.
With gpon its very very easy to do with larger downloads. Two users on a pon downloading say 90GB will cause others to have issues if they want to download too . Thats why olts have software to reduce such situations.
if you download at 500mbits that is within parameters- the system is designed for that as well.
we don't know how you've set up your TP-Links, some features on any router can impact performance. For instance vpn services may impact thruput via the vpn tunnel - etc.
One thing i haven't mentioned is this, you opened two threads on two forums which were not urgent, hoping maybe for some different advice. You talked about others on the kitz's forum - which dissuades people from helping you.
Multiple people have told you, that your network is working as a normal home network.
