[itaaa1314]

Hi guys, Im having a problem with my internet. this problem happens everytime i launch a Steam app and my internet disconnects right after i start the game(PUBG). And im receiving warnings in the event log. Other games are working fine, just steam games wont let me connect.

Router: Model: C3000 netgear

THings i tried:

change DNS to google dns,

reinstall steam and PUBG, reinstall windows 10,

 bought a new netgearrouter (C3000) and it worked fine for around a month and it started to get Warnings 2 days ago.

The power levels are out of spec. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, and latency problems.

In a self troubleshooting effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage types like GE, RadioShack, RCA, Philips, Leviton, Magnavox, and Rocketfish from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test

If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed, and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.

@EG 

ill try to plugin therouter somewhere else to see if it fix the problem tomorrow.

And ur words are a bit too professional for me, can u rephrase some of them with some more simple words for me. thanks.

Hi @EG 

The power levels are out of spec." what do u mean by this?

if i buy another brand for my modem router, will that solve the problem?

[EG]

It simply means they are not within the required ranges for proper / normal modem operation / performance.

And no. Another modem will not fix a line / signal / connection quality problem that exists. It will still be there no matter what modem is used.
