Finally decided to post on a forum dedicated for these kind of things.
Anyway, since last week Thuesday my internet (cable modem) shut off. I was like huh? Thought i'd restart my pc & it would come back as i had this before in the past. After pc restart, still no internet on any of my devices, so i went to check the modem (motorola sb5101e) and it had 0 lights not even power light was on. I assumed it died. However before internet died i was playing an online game (worldofWarships) and i was experiencing sudden Latency spikes which i have never experienced before in like 10 years.
So called the ISP support next day & let a techie guy come over whom determined that modem has died but then he found out along with me that power outlet was also not giving out any electricity. Still he replaced the old modem (from 2004) with a brand new modem-only as requested (cbn cv7160e).
Finally i got the internet but with the same issue: latency spikes almost every 5secs in all games, also everything else lags too. My voice stutters on any voice server, skype stutters aswel along with every other communications app on any device. Either connection is lost or is very poor during viber/skype and anything alike.
After reading a lot of topics over the net, i still can't pinpoint what's going on.
Yesterday i learnt things like: pinging, pathping, traceroute & tracert.
In the garage there is that newly replaced modem but upstairs i have my own router (linksys e3200). So far over the years this router has been fantastic. No issues as far as i know.
However, today i disconnected it & directly connected my gaming pc to modem. The spikes still remain.
* Pinging to my default gateway (modem i guess), shows 0 packet loss or spikes (done continious pinging too)
* Pinging to my adress again 0 packet loss or spikes
* Pinging to google.com shows 0% packet loss but somewhere in 15m the request fails (out of 3000 packets only 4 failed).
* Pinging to telenet (my isp) before showed a lot of packet loss.
* Currently pinging again with cmd & pingplotter (sometimes use MTR too).
* According to Pingtest.net on multiple server there is 0 packet loss & 0 or below 5 Jitter.
* According to speedtest.net my down & up speed are max.
* Pinging to DHCP server shows very high % PL but after ever 2.5sec it keeps dropping. Wtf?. (Pingplotter)
* Pinging to one of ISP DNS server same result. These both last have PL at hop 2. (Pingplotter)
* both DNS servers show at hop 2 PL.
* Pingplotter shows PL while CMD does not? How is this possible?
Some images below
No packet loss to my gateway ip & my ip means that my modem & pc are fine right?
I want to try everything possible first before i call my isp to show/tell what i've done so far.
I'm willing to run other tests aswel but i only know this much .
Whether my router is connected or not, the above still happens so it does not matter, i just wanted to rule out my router.
What methods should i use to rule out my pc, modem, router or isp? Like in what order?
I've also done tests through Network Diagnostics and here are the results (attachment files)
Any ideas or insights are more than welcome.
