Constant latency spikes and packet loss

This has been going for more than 3 weeks now and its becoming more and more unusable internet, happens with wired and wifi, will disconnect out of games when it happens, twitch and youtube etc will start buffering while it happens its just unberable.

Live BQM (have it up for few weeks can send more days if needed.)

Re: Constant latency spikes and packet loss

Spoiler
 

Got new hub sent today, plugged it in but its still happening. 

New Hub live BQM 

New hub network logs show t3 timeouts and not only those when i get those droops of internet. Also are those pre and post RS errors normal for a new hub and just 5hrs uptime? im getting tired of waiting for a fix that no one seems to know.

New Hub data below

Re: Constant latency spikes and packet loss

Good Morning @VitorG18 

 

Thank you for your post. 

 

I have noticed that you also have another thread, please try and keep to one thread as posting multiple threads will delay the response to not only yourself but to others as well.

 

I am going to drop you a PM so that I can look further into this. 

 

Kind regards,

Zak_M
