Edimax EW-7711USn USB Wireless Driver Problem

**erdibav** · June 22nd, 2012

Hi
I m new to Ubuntu, Linux and this Forum
I just install Ubuntu 10.04 with Wubi. Everything work nice but my USB Wireless Adaptor.
http://www.edimax.com/en/support_det...=303&button=Go

I have downloaded driver from;
http://www.ralinktech.com/en/04_supp...ort.php?sn=501
and follow the README file but when it comes "/sbin/insmod rt2870sta.ko" throws "insmod: error inserting 'rt2870sta.ko': -1 File exists" error

This is my iwconfig;
lo no wireless extensions.

eth0 no wireless extensions.

wlan0 IEEE 802.11bgn ESSID

ff/any

And lsmod

I m using my ethernet card to connect but wireless adapter would be nice and tidy cable mass. What is wrong with this, any help? Thanks

Hi, welcome to the forum! Please open a terminal ctrl+alt+t copy and paste the following commands into it one line at a time, then paste the results here:

Code:

cat /etc/lsb-release; uname -a
lspci -nnk | grep -iA2 net
lsusb
iwconfig
rfkill list all
lsmod

by clicking on new reply and click # then paste the information between the brackets.
Thank you

I think my buddy the Wild Man would like you to add another step:

Code:

sudo su
echo "blacklist rt2800usb" >> /etc/modprobe.d/blacklist.conf
exit

Reboot with the ethernet detached and give us your report.

**erdibav** · June 22nd, 2012

Thanks for your interest, after blacklist rt2800usb, disconnect usb adapter and reboot. All i get is this. And "rfkill list all" returns nothing.

Previously, you had rt2800usb AND rt2870sta loaded. They conflict. The usual fix is to blacklist rt2800usb and let rt2870sta do the work. Now, even rt2870sta is missing. Let's load it explicitly:

Code:

sudo modprobe rt2870sta

Does that help?

Code:

iwconfig

**wildmanne39** · June 22nd, 2012

Hi, chili555 is correct,

I think my buddy the Wild Man would like you to add another step:

I did suspect that as well, it has been a long time since I have seen this card with 10.04 so I just wanted to double check.
Thanks

**erdibav** · June 22nd, 2012

Now i can scan networks around me but cant connect. its trying about 1 - 2 mins and ask pass again. Double check pass and i can connect with my phone to wireless network. This iwconfig while its trying to connect

Hi, please post the output of:

Code:

nm-tool
sudo iwlist scan
lsmod | grep rt2
dmesg | egrep 'rt2|wlan|wpa|etork'

EDIT: You can not be connected to the internet through this computer with your wired connection or phone to be able to connect with your wireless so please disconnect all other connections before trying to connect with your usb adapter and before running the above commands.
Thanks

Hi, unplug your wired connection then see if it will connect, I also recommend changing the encryption in your router to just wpa2.

I believe you may be having issues because of the _ in your network name remove it in the router and network manager then reboot and see if it connects.

EDIT: After you do all of that if it does not connect post the output of:

Code:

sudo cat /var/log/syslog | grep wlan | tail -n45

Thanks
