It really depends are you seeing the spikes after the 3rd hop, if not then its not causing a problem during transit only on request, Which is common on some of BT Network Nodes
when you say latency what sort of Latency are you seeing a constant high ping or just an occational Spike?
are you running off wireless or Ethernet?
have you got a copy of the traceroute or Pathping which you can send on?
yeah that hop will occationally spike to 200MS by standard, its all depending on what the end location ping time is and packet loss is like,
have you tried a new router?
It isn't necessary to take a new router. I had problems with the delay at https://duckdice.io But it was not on the Internet, just my router settings were lost. I used the instructions and installed new firmware. This saved the situation. I think this problem often arises, but it is most often noticed by gamers.
