Slow Internet Speeds on only one computer. [SOLVED]

[BajungaDustin]

My main computer has not been maintaining full internet speeds while my phone and tablet are?

I pay for 30/5 internet and my down lately has been super slow on my PC. hitting as low as 0.4Mbps up to 34Mbps. Over the last few weeks, it's been hovering around the 4 to 17 range.

I monitored it closely one night for 4 hours and noticed really slow speeds.

So after contacting my ISP and they came out we realized that this was my problem and not theirs. More specifically... it was my single PC getting low speeds. NOTHING ELSE.

My phone pulls 34Mbps consistently through the WiFi on the same network. My laptop pulls 34Mbps while hooked up to the modem and via WiFi. My Tablet pulls 30Mbps through WiFi. My computer pulls crap from the router or while hooked up to the modem.

I have installed the most up-to-date drivers for my NIC and the ones that came with the mobo disc and still crap.

I have uninstalled it and reinstalled the NIC and nothing is working. I just reinstalled Windows yesterday and still nothing. I bought a wireless USB adapter and STILL pulling around 10Mbps right now.

And yes, I tested this with ONLY the computer connected and no devices. I have checked all my cables and ruled out any damaged cables (even though since the WiFi is working for everything else, I know my problem is not in my router or modem.)

The problem exists on my computer alone regardless of connection type or path and is pulling crappy numbers from a network that is putting out great numbers. So, the problem has to be internal on my computer. But what could it be???

OS:-----------Windows 7 Ultimate x64
MoBo: --------ASRock FM2A75 Pro4-M
Processor:----AMD A8-5600K APU Radeon HD 7560D
Graphics 2:---AMD Radeon HD 7850
Mem:----------Corsair Vengeance 16GB (2x8)
BIOS:---------American Microtrends vp2.10 3/14/2013
NIC:----------Realtek PCIe GBE Family Controller
Router:-------Linksys WRT160Nv3
Modem:--------ARRIS CM820

First time after 3 months I was able to fix my problem of slow internet only on my laptop irrespective of other laptop or phone which were doing fine. It was about time when I decided to change my network card i.e. Intel Centrino W2200 and was looking for new internal drivers where I found you have to flash the bios to avoid the whitelist by lenovo. Anyway enough of background crap, let's talk about the solution which might help others too..

You have to disable the 802.11 n Mode.

And this is how you will be doing it-

1. Type Device Manager in search.
2. Goto Network adapters
3. Right click on the Wireless-N 2200 adapter or whatever you have installed and choose Properties
4. Click on the Advanced tab
5. Select 802.11 n Mode and set to Disabled
6. Select Ad Hoc QoS Mode and set to WMM Enabled
7. Select Wireless Mode and verify it is set to 3. 802.11b/g
8. Click on the Power Management Tab and uncheck box Allow the computer to turn off device...

It worked for me and save me from buying another internal card and its flashing process.
I hope it will work for your system too.
PEACE

Thank you so much! This is exactly what worked for me.

same thing here, brand new build,
i7 4790k
asus z97-a mobo
nvidia gtx 980
windows 8.1

Cannot find anything that can fix this, internet is fine on my old computer, has anyone got any more ideas?

look for Asus GameFirst I believe it comes with your Mobo. If not then its a similar Asus application. My hero came with gamefirst and it had the same issues

I had the same issue until I saw this post. I don't have the AMD Quick Stream program but I do have the Killer network manager program on my computer. Because I got a killer internet port on my MSI motherboard. That program you can set bandwidth control and I end up enabling it somehow, so I just unable it and I got my 100 down and 40 up again.

I just registered to post my solution after hours of searching and experimenting with different processes.

Firstly, thanks for all your comments and answers. Without them i wouldn't have found the solution, but mine was slightly different. (My comp is amd and does have nividia).

Anyway, cut to the chase this is a follow on post from "6host's" post.

After doing the following from his post:

1. Type Device Manager in search.
2. Goto Network adapters
3. Right click on the Wireless-N 2200 adapter or whatever you have installed and choose Properties
4. Click on the Advanced tab

I then selected:

5. Wireless mode
6. Value: change from wireless mode ieee 802.11b/g/n to wireless mode ieee 802.11b/g. I suspect these values may be different for each adapter. For me there were 3 different values, 2 had crap speeds and 1 was great.
7. Ok

My speed rocketed after doing this simple change.

Hope this helps.

I tried all of this but still cant get anything more than 0.18 download speed and when I go to the Network adapters I have Adhoc support 802.11n to disable and country Region (2.4Ghz) to #0(1-11) and 3 other options if someone could hep that would be great

HERE IS THE FIX TO A MAJORITY OF THE INTERNET PROBLEMS YOU MAY BE HAVING PART 1

So I recently purchased a Network Adapter (TP-Link WDN3800 <--- Model No.) This device was stated to give me speeds of up to 300 MB/S operating on both 2.4GHz or 5.0GHz bands, However when I Installed it and ran an online internet speed tester provided by Ookla (Here: http://bit.ly/18kSQZ9) I was receiving awful download speeds of around 1 MB/S, I uninstalled the the device and reinstalled it multiple times, attempted to change the Internet Settings on the computer and nothing changed. Turns out it was a hardware issue not bad configuration by software.

FIX

• 
  According to this forum some people are having issues with a program called AMD Control Centre or something like that which seems to montior and reduce network traffic, search for the program location and either uninstall it or tweak its settings.
  
  Now this method fixed my issue and should work for other users that do not have the AMD Software. If you look on the back of the router there should be an address that you type into your browser to let you access and control your network settings such as your password, frequency band etc... When you access your webpage it should ask you for your pin, this can also be found on the back of your router. Once you access your network settings change your 2.4 GHz frequency to 5 GHz and save it.
