Ok, my cousin and i built the same PCs around 3 years ago, we bought exactly the same wifi card, a Qualcomm Atheros AR9485, thing is 6 months after having built our PCs my cousin started having troubles with his wifi, basically the adapter started "dying" in the sense that the PC would boot up, have good connection for a few minutes, then slowly the connection would die until he only got err_timed_out and after that nothing would load. Well, he went and bought a USB TPLink wifi adapter and he hasnt had much problems since then. Today i came to his house and brought my PC and put it in his room... and 5 hours later i start having problems with the wifi, the adapter usage is dropping to 0% every 3 or 4 seconds, i start getting err_timed_out on google chrome, and after 6 hours i no longer have a wifi internet connection, im still conected to the router but the wifi adapter usage shows 0% and refuses to increase even if i am searching in google (i get timed out). Drivers are updated and i have never had a problem like this at my house, i should mention i stayed here for a few days some months ago and since then ive noticed a bit of intermitent wifi problems at my house in the same fashion (drop to 0% usage) but they would last only for 1 or 2 seconds every 5 minutes or so and I would never get timed out. I fear being here is slowly killing my wifi adapter. I had a hypothesis that it could be some electrical interference messing with the wifi adapter but im not sure if that is even possible neither how to test it. Note: We havent tried puttin the pc in another room, we are in the same room where his wifi adapter started failing. Phone wifi works flawlessly, modem signal is no problem, and i really dont know what it could be. No microwave nearby nor in use. No channel congestion neither other wifi APs. Any insight will be appreciated. TLDR; Built 2 PCs with same components, on one house the wifi adapter begins to fail 6 months after being built. Now i come to the house and my adapter starts failing in the same manner.

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.

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.

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.

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)
