Cant game online

[Darklord_Pr3d]

This is not my personal problem but his. Me and my cousin built a PC about a year ago, nothing out of the ordinary, we played online games well for the first week. Then after that we didnt play much anymore, but for some time now he has tried playing online but as soon as he opens the game his connection goes terribly bad to the point that not even google loads properly. It ONLY seems to happen with the online game (The game its Dota2,  we only got one online game ATM, gonna try others soon), we have tried offline games (AKA games that have 0 multiplayer features, neither communication throught the internet) and the connection is fine. His connection is a 5Mb (megabits) down and 2 Mb up (Its an Arris Router, 2.4Ghz)

 

Here are the main specs of the PC:

CPU/GPU (APU) : AMD A10 7850k (No OC)

Ram : 8 GB 2113 mhz 

Motherboard: Gygabyte GA-F2A88XM-DH3

PSU: 430w EVGA 80+ bronze

Wifi adapter: Qualcomm Atheros AR9485 

 

 

Here is what i have tried:

-Disabling the firewall

-Updating the wifi adapter´s drivers

-Disabling the router's firewall function

-Checked for malware and updated the antivirus

Haven't tested ethernet connection yet.

 

Here is what i have noticed:

- Opened up Resource monitor, downloading on steam at 500KB/s and right when the game finishes loading the download speed goes gradually down to 0 bytes(I activated the downloads while on multiplayer games to test this. It slowly goes from 500KB/s to 0, takes about 15 seconds) 

Its like the game making connection to the internet consumed all the bandwith, except its not: The game uses way less than a 1 megabit in the main menu and, due to the slowly killing of the bandwith, the internet completely dies and the game itself loses connection to the servers. Then when i close the game the game window closes but the process still remains open for about 10 to 15 seconds, during this time the internet is STILL dead, once the process is completely out of the processes list the internet starts rising slowly back again until its at is peak download speed.

 

-I have thought that it might be the wireless adapter, but the internet works perfectly fine until you open up the game.

One thing i have noticed though is that on his device manager there appear about 5 o 6 different network adapters that are NOT in my device manager (using exactly the same motherboard and wifi adapter). 

 

Any help diagnosing the problem would be aprecciated.

 

EDIT: Forgot to include some other details:

No other routers are in the area (Arris router set on channel 3, TX power set at 100%)

Haven't tried disconnecting all the other devices from the network (There are around 2 devices more connected, cellphones)

What is your internet company and did they tell you that you have monthly bandwidth limits? It sounds to me like you're being throttled or have something downloading in the background like Windows updates.

Whats kind of ping results are you getting? 

[Darklord_Pr3d]

There are no monthly bandwith limits on this connection, have checked on resource manager: No other background processes using the internet (no receiving or sending packets). As i have said, the internet functions normally until gaming.

Without gaming between 13 and 50ms to google.com 

When the game has finished loading the ping fluctuates widly between 13 and around the 1000ms then some of the packets start to be lost.

This might suck but try to run a cable to the PC or move the PC close enough to the router to get an Ethernet cable plugged in and see if it changes anything.

Well, didnt test ethernet yet, but i did the following and the problem seems to have kinda fixed:

 

opened up cmd

 

ipconfig /release

ipconfig/renew

 

restarted pc and router

 

Now i can game but with a lot of lag spikes, have been checking the resource monitor, the lag spikes....are weird, usually when gaming the whole network usage is around 500 Kbs....but when it goes up to 1Mb (remember its a 5 Mb connection) the ping rises from 60 to 1000 with an average of 300, this happens even with no other active applications running.

usually happens every 3 mins (rarely happens twice or more in one minute) or so and the duration of the lag spikes most of the time is about 1 second and has a maximum duration of 5 seconds.

 

Also tested another game, Left for dead 2: Same problem, the lag spikes are way more notable on this game, its almost unplayable.
