Internet speed sporadic

Greetings,

I just installed a 64bit version of Zorin and I love it! However, my internet speed is very sporadic, sometimes it throttles down to dial-up speed. When I use boot into win7, my internet connection is fine, as are my other devices on my network.

Anyone know what Linux magic I may have to perform to get the connection working like normal? I'm a linux noob. BTW, my network adapter is a Realtek PCIe GBE Family controller on a MSI P67A-G43 Motherboard .

Hi,

make sure that the network connection is available to "all users" and "connects automatically", you can do this by clicking on the network icon in the taskbar, then select, edit connections.

You can also check to see if there is a sepcific MTU for yor network adapter online, type something like:

"best MTU for Realtek PCIe GBE Family controller" in Google!!. It is set to Auto by default!!.

I believe that this should help you a lot. As I suspected, you are probably using the wrong driver. Follow the instructions and let me know if it helped.

P.S. Make sure to download the correct driver (the LINUX driver for kernel 2.6.x).

Wow! I was looking for an article to fix that. After doing this, my internet connection is solid. Thanks Madvinegar!

As you can see I do have a Realtek but it is not the same one listed in the article.... any ideas?

Madvinegar,

I am having the same issues, I have a RealTek as well but mine is not the one listed in the article. I have a RTL8101E/RTL8102E. Any ideas on what I need to do? I am a 1 day noob on Linux.

Sweet, I will give it a try.

Before doing anything else, could you please post the outcome of:

Code:

rfkill list

rfkill list response

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

Ok thanks.

Actually your wireless card is Atheros AR5001.
I have read somewhere that this card works better with madwifi (rather than network manager). So this is what I would have tried:

To get the latest madwifi drivers go here: http://madwifi-project.org/ but make sure you download the correct ones that are for kernel 2.6.25 or newer. (Zorin 5 uses kernel 2.6.38-13). In the link I gave you, 6th line or so, says "In case you use kernel 2.6.25 or newer, you need to get this snapshot of the madwifi-0.9.4 branch instead ".

So, download the madwifi-0.9.4-current.tar.gz file, i.e. in your "downloads file" and extract it by right clicking and selecting "extract here".

Place the extracted file at your "home" folder.

Then open a terminal and write the following:

Code:

cd /home/<your name>/madwifi-0.9.4-r4178-20120131
sudo make clean
sudo make
sudo make install

After that do a

Code:

sudo modprobe ath_pci

and see if you will get better connection.

If it works, in order to make changes permanent you need to go to the /etc/modules file. You can do that by writing in terminal

Code:

sudo gedit /etc/modules

and add the line

Code:

ath_pci

Save and exit. This will ensure that the driver is loaded at each start-up. Hope this helps!

wow that is alot...I will give it a try.. and thanks for doing so much work... I can't tell you how appreciative I am.

Dude it is working perfectly!!!!!! You are awesome!!!!

I am so happy when all works out just grrrrrrreeeaaatttt !!!

Glad I helped my friend!!


@swarf: I know that it is becoming a habit but please give me my blue jewels!

I spoke too soon...it is now erratic again....

Hi,

did you check the 2nd post in this thread and try any of the suggestions??.

See also:

Regards Wolfman

Open a terminal and write:

Code:

sudo gedit /etc/modprobe.d/blacklist-ath_pci.conf

If you see in the end a line like this

Code:

blacklist ath_pci

uncomment it by inserting the "#" sign in front of it.

So, it should look like this

Code:

# blacklist ath_pci

Save the file, exit and reboot.

Mad, I did have to put the # mark in front of it, but it doesnt seem to have made any difference. If I disconnect and reconnect to my wifi, it seems to work for a few a minutes and this goes off and on again.

Wolfman, I did that as well and they are both set correctly.

After you connect and it disconnects again, please open a terminal, run and following commands and post the results:

Code:

dmesg | grep wlan0

and

Code:

sudo lshw -C network

and also one more time

Code:

rfkill list

Also try something else.

Open a terminal and write

Code:

sudo modprobe ath5k

and see if your connection will become better.

If it does, we will use this driver, and so we must do the following to blacklist the previous one (i.e. the ath_pci).

Open terminal and write

Code:

sudo gedit /etc/modprobe.d/blacklist-ath_pci.conf

and remove the "#" sign in front of the "blacklist ath_pci" line.
Save and exit.


Also open again terminal and write

Code:

sudo gedit /etc/modules

Delete the ath_pci line that we have writen and replace it with ath5k

Save, exit, reboot and let me know.

Sorry been on vacation... Will try this tonight and let you know the results.

Ok Mad, I have done those things and I will wait a few days t see how this works before rejoicing too much this time! lol Thanks in advance!

McDuce wrote:Ok Mad, I have done those things and I will wait a few days t see how this works before rejoicing too much this time! lol Thanks in advance!

At least, is it working ok for now?
Please keep us informed of developments!

Still in and out. Sometimes rebooting helps sometimes it doesn't.

Anything else guys? I am thinking of trying another OS? Any suggestions?
