Internet Connection drops once every 25s~

[OnceUponATime]

Dear Computer Hope community,

I tried my question in chat but unfortunately it wasn't all too busy so hereby posting it on the forum.
For a good 7 days now my computer would disconnect itself for about 1-2 seconds each 25-30seconds from my network, thus stopping streamed music/Skype/Teamspeak/Online games.
At first I was having issues with my router, the usual; crashing and/or not letting me browse, this was caused by old age and I have since then replaced my router.. these random disconnects continued though.

Here's a quick screenshot of my internet usage, this is about 1:00 - 1:30

You can clearly see the dips in the usage.

I updated my ethernet driver as a hint from the chat, silly that I didn't think of that myself.
I'll try to list my computer specs and any other information I can think of to aid you in aiding me.

Computer:
Motherboard: Asus P8H67 V3.0
CPU: Intel core i7-2600
Memory: 16 GB DDR3
1x SSD 120GB + 1x 2TB HDD SATA
GFX Card: Asus EAH6870 DC/2DI2S/1GD5
OS: Win7 Pro 64bit

Internet:
100mbit Down - 100mbit Up
LAN -> Desktop and Ps3
Wireless -> Smartphone

Regular Services:
Skype, Steam, Teamspeak, Grooveshark,YouTube, Waterfox (64bit firefox).

Games:
Battlefield 3, Team Fortress 2, PayDay 2.
All are affected.

Newly purchased router:
TP-LINK. Model: TL-WR1043ND

Kind regards;

look in programs for Pando Media Booster and uninstall it if its there.

what protection apps do you run for virus and malware?

Do you have a direct wired Internet connection?
If not, why not? Any wireless introduces another lawyer of issues.

I do, maybe I wasn't clear enough in Internet: LAN -> Desktop.

I found this little bugger about 6 months ago, made sure to get rid of it back then.
It's not that there now so I don't think it's caused by it.

Symantec Endpoint Protection (licensed) for firewall/network security and viruses. On occasion free version of Spybot Search And Destroy and CCleaner

[lostcoast]

I would start by uninstalling endpoint and testing after reboot...you can always reinstall...then remove spybot and run 2nd test.

IMO spybot should be replaced with paid malwarebytes pro.

IMO  don't use ccleaner registry cleaner.

If it is endpoint or spybot, I would use free avast and malwarebytes pro paid. (it's what I use)

just my 2 cents

[Geek-9pm]

My two cents.
In Safe mode you should get internet with direct LAN from the modem/router.
Once you establish  problem is not your ISP, you can work on local things.

[Computer_Commando]

Cable modem or DSL modem?
Drops can be due to marginal signal quality.

It wasn't endpoint, but a valid suggestion, wasn't spybot either.
Not sure what to think of the objection to CCleaner.. but I made sure it wasn't this either.

Have not yet tried this.
I have, however contacted my ISP and inquired about the stability of the Line to my home, this all seems to be fine without any hickups.

Unfortunately I wouldn't know the answer to that, if it adds anything.. it doesn't have DHCP, hence the router.

results of safe mode would be nice to narrow it down a bit.

I tried safe mode, with network ofcourse.
Seeing as I didn't have Symantec's network usage monitor I couldn't use that.. or a video game that may or may not get internet problems, so I've used http://www.bbned.com/speedtest/ - For those unknown, it's a website that grants the user that downloads a .bin file the full internet speed of his/her ISP, in my case 100 mbit.
Results:
Safe mode: Steady 11.5 MB/s
Regular Mode: Steady 11.5MB/s BUT once every 25s it goes down to 9MB/s and back up to 11.5 MB/s again.  It looks like it doesn't get the chance to drop the 0 before picking it up already.

I hope this told you guys a bit more.

its something in windows then obviously...back to my 2nd posts advice.

Tried them both, problem still persists.

Open for other suggestions

I guess its time to dig into processes and also resource monitor for a clue.  There also may be a processor usage spike when this happens.

Installed, opened and reading tutorials, give me a minute.
Turned out to be more than a minute.

Found some interesting occurrences:

   

As you can see I've added two disks screenshots to show it wasn't an anomaly.

For some reason the edit function on my last post isn't working so I was forced to make an unwanted double post.

Last night I noticed my phone disconnecting itself from the Steam services via the app.
It connected to my WiFi again and connected as it should to Steam.
This made me wonder and this morning I booted my computer in Safe Mode and used Resource Monitor to see my network status.
I was actually surprised when I saw this:


This is during the download of the 1 GB file of the BBned site posted above.

Maybe my computer isn't source of this issue?
