wifi usb issues

I am using a new wifi connection with a dlink dwl-g122 usb adapter. I only get 2 bars of reception and the connection keeps dropping all the time and only way to establish a new connection is to take it out and put it back in. I did get a cd with drivers but they are for windows. How do i get the drivers for linux?

Please plug the usb stick, connect to internet and post back the results of the following commands:

sudo lshw -c network

bump

Before compiling any new driver or checking if there is any conflict can you please check 1-2 things?
First of all I see that your link quality is a little low. Have you tried changing channel to your router? Maybe the channel you are on is very busy.
With the following command you can check which channels are available for your adopter:

Code:

iwlist wlan0 channel

With the following command you can check how many others are using the same channel as you:

Code:

sudo iwlist wlan0 scan | grep Frequency | sort | uniq -c | sort -n

Please post here the results if you like. Maybe if you just change channel in your router, you will get better and more stable performance.

An just for you info:

Signal strength is a simple measure of the amplitude of the signal that is received. The closer you are to the access point, the higher this will be.
Link quality measures the number of packet errors that occur. The lower the number of packet errors, the higher this will be.
If you are very close to an access point you will get high signal strength, but you might get low link quality due to a microwave oven or cordless phone in the area causing interference.
Conversely, you might be very far from the AP and get low signal strength, but high link quality due to the absence of any RF interference, multipath, etc.

Also, next time your connection drops, open terminal and post back here the results of

Code:

dmesg

The results of the last command are going to be very large, so please put them within code tags. You may have to set your terminal to infinite scrolling (tools > scrolling > infinite).

Hi zorin0s, I'm afraid bumping does not work on this forum! All Moderators are volunteers and madvinegar is the wireless expert for this forum - so please bear this in mind when posting in future.

Any "bump" recurrences will be deleted!

it seems to drop out as soon as i go to watch a youtube video or play games online. When i use wifi on my samsung galaxy s2, the wifi works with no issue. Just seems to be the usb wifi on mypc. Also it would not let me paste the full results of those commands here because it was too long so i put it in pastebin.

I want to test two theories.

1) Plug the USB stick on another usb port. How many do you have? Try each one of them and see if you have any wifi drops.

2) If the above will not work, lets try to disable the power management of wlan0 so as to give full power to the wifi. (Are you on battery or on power?)
Run this command in terminal

Code:

sudo iwconfig wlan0 power off

Test to see if wifi has problems or not. If it does not have any drops, we can make this permanent.

tried different usb ports and that command. still dropping out as soon as i play video games and try to watch videos.

Ok, since we ruled everything else out, lets see if you have any conflict with other drivers. I have a feeling that you may be conflicting with the "rt2800usb" driver.
Can you please post here the result of

Code:

Try also this. In terminal give the following two commands:

Code:

sudo rmmod -f rt73usb
sudo modprobe rt73usb nohwcrypt=1

If it works, we can make it permanent.


However, I am starting to think that the driver is OK ( I do not see any conflict in lsmod) but I think that the problem is your USB slot.
I looked again in your dmesg and I found this specific error repeating 100 times.

[  465.594980] usb 3-8: USB disconnect, device number 2

After this error, the usb disconnects.
I searched in google and I found that this is an error related to USB ports and is corrected in later versions of the kernel.
You said you tried with other usb ports in the laptop. Are you using Zorin 6?
Could you also try with a newer release of Zorin? either zorin 7 or zorin 8. No need to install it. Just prepare a live usb or CD, boot to the live desktop, plug the wireless usb dongle and see if you get drops.
If not, then we can try to backport a newer kernel into Zorin6.

can we try to backport a newer kernel into Zorin6? i cant download because it keeps dropping out

Have you tried the following:

Try also this. In terminal give the following two commands:

sudo rmmod -f rt73usb
sudo modprobe rt73usb nohwcrypt=1



If it works, we can make it permanent.

All that did was disconnect me and it was trying to reconnect and never did. had to take it out and put it back in to re connect

Ok, try it like this:
In terminal:

Code:

sudo gedit /etc/modprobe.d/rt73usb.conf

A blank document will open. Add inside it the following line:

Code:

options rt73usb nohwcrypt=1

Save, exit and reboot.

After the reboot see if you get any drops. If you get drops, reboot again and after the reboot give also this command in terminal:

Code:

sudo iwconfig wlan0 power off


Test again if you have internet drops. If not, we can make permanent the second command as well.

ZorinOs did you check my above post? Was there any improvement?

However I believe that by disabling the N band frequency, as well as the power saving of your card, you will get good results.
Please let me know.

P.S.
In case there is any problem with the last command I gave you, you can just delete the file we created

Code:

sudo rm /etc/modprobe.d/rt73usb.conf

and reboot.

Still dropping when i go to watch videos online and gaming. After i typed that command it kept disconnecting and wouldn't log back in. only way i could re connect to the net was to restart my pc over and over again

Very sorry to hear that. I am out of ideas. I googled again your problem and the best page I found is one that proposes exactly what I propose.
http://lucas.fitt.net.au/2012/07/07/fix ... ntu-12-04/

Your next best shot is to update to a newer version of Zorin with a newer kernel and see if this problem has been fixed.

Hi,

have you tried booting the PC without the USB stick and then inserting it; once fully booted?.

Regards Wolfman

The last resort would be to use the windows wireless drivers software (ndiswrapper). I have written a detailed guide here:
viewtopic.php?f=6&t=5008&p=23910&hilit=ndiswrapper#p23910

P.S.
In case there is any problem with the last command I gave you, you can just delete the file we created

Code: Select all
sudo rm /etc/modprobe.d/rt73usb.conf


and reboot.


How do i delete this? i can't even connect to my connection now

You don't need connection. Just get in desktop, open terminal and issue the following command:

sudo rm /etc/modprobe.d/rt73usb.conf

Then reboot.
