For some odd reason my internet speeds are fluctuating between 5 kb to 20 mb/s

This used to occur frequently on my laptop (only for a couple of minutes though), but it's very rare on my desktop

I've tried: restarting router, restarting network adapter, trying different bandwidths (802.11g/n is the default), and making it intolerant to fat channels.

I've even tried placing it next to the router (where my desktop is)

both my desktop and laptop use wireless cards

Desktop uses a USB wireless adapter, and the laptop uses the n2230 centrino adapter.

When the network connection to the router is 100+ mbps (from task manager), the laptop starts to heat up (to around 60 F, according to speedfan). My network usage always remain under 5%, and anything that requires network strength (downloading WoT for example) causes the connection speed to the router to go DOWN. It's been as low as 0.05 kb/s...

Although it's not very common now (after a driver update), it's still happening (and each time this occurs it lasts around 10-20 minutes at a time)

I'm so confused (._.') (Sorry if i typed a bit too much).

Hi flametz :)

 

Please post the operating system, computer model and router next time. What software is being used to monitor the bandwith speed and activity when the problem occurs?

Download MiniToolBox and open/run the program.
When open, checkmark or select all options then click Go.
A notepad will open then copy-paste the report on your next reply.

Desktop is custom made, has no problems for 2 months now.

The laptop is a Vostro 3460 with all the options slapped on.

Laptop uses Windows 7 Ultimate 64-bit, has 8 GB RAM.

Used task manager to view connection to router, and rainmeter to view connection to internet.

the log is MONSTROUS, are you sure you want me to c/p the whole thing?

Does it mean it happens on both computers? Yes, please post the logs on the troubled computer.


Used task manager to view connection to router, and rainmeter to view connection to internet.

I have never used task manager (networking tab) nor Rainmeter to view my current bandwith speed or network traffic as usually the general ISP test speed is using speedtest site. There may be some conflict readings between the 3rd party software and the speedtest site but it is worth using the cross reference readings by using both of them. Rain Meter net measures http://docs.rainmeter.net/manual/measures/net and free network traffic tool http://www.majorgeeks.com/files/details/netbalancer_free.html See the comparison if one would serve you better along with the speedtest site.

Ah, no... sorry if i made this unclear...

It only happens on my laptop (for now), here's the log from before:

(Oh man i wish there was a [spoiler-] [-/spoiler] option...)

Edit: WOW there really was one...

speedtest only measures internet speeds on any given moment. I use something that monitors my connection constantly

netbalancer is currently showing all the data my programs used...

not too useful, but it helps with other purposes anyhow

Someone very knowledgeable with these software monitoring tools may come along but as of now there seems to be nothing wrong with your current logs.


Used task manager to view connection to router, and rainmeter to view connection to internet.

How do you monitor the connection by task manager? Most likely you are referring to the Network Utilization or simply the processes and priorities windows system use on your current bandwith like BITS or other applications installed that requires daily updates. The network utilization link would give you the overall picture and see also the capabilities of netbalancer.

Task manager, network tab, and on the bottom it shows link speed to the router.

and netowrk usage (which always remain under 5%)

My desktop can get that speed just fine
My laptop... Doesn't
Anywhere from .5 kb/s to 20 MB/s

I assume you are using a passkey on the wireless network (i.e. using WEP, WPA or WPA2).

If so, out of curiosity, have you tried temporarily turning off the encryption and see if things get better for the laptop? I kind of doubt it will help, but it is worth checking.

Alright, nvm. Found the problem.

Heat.

Been monitoring temps with SpeedFan, and it seems like anything above 70C and the network adapter starts to "stutter"

... and for some odd reason my gpu hits 75 C when watching youtube ._.

Currently using an old cooling pad to keep the tempuratures down.

Actually, when the tempuratures get under 0 C, the network card gets the same problem too (don't ask, left this computer in the freezer out of curiosity).
