For the past few months, I have been experiencing major packet loss on all hops after the second. After getting a new modem from my ISP, the issue has decreased in severity, but the problem arises at least once a day. This leads to large ping spikes when in games, as well as voice and video dropped from programs like Zoom and Discord. I have also upgraded my home recently with gigabit, yet when downloading large files, like a game, there is large amounts of ping spikes and packets dropped on all hops.

So far things I have done:
New modem from ISP
Contacted ISP multiple times, every time just ends in a restart of the modem.
upgraded internet to gigabit
Bought a third party modem
Replaced ethernet cable from modem to router

Any help would be appreciated.
