Ubuntu Networking :: Edimax EW-7711ln Recognized But Cannot Connect?
Jan 25, 2011
I have two PCI network cards: Wired - Successfully connects to the internet and removed from the outputs describes below. Wireless - A new and works well in WinXP - Edimax EW-7711ln: problematic - can't connect. Manufacture says it's supported in Linux. Although in it's site it doesn't have any linux driver to download. The XP driver contain 2 .cab files that cannot be accessed using unshield/cabextract so I guess "ndiswrapper" is not an option. Other Linux disrtos also didn't recognize the wireless as well. Below I added as much information as I could get.

I am (was) trying to setup my Edimax EW-7711lN PCI WiFi card. My original post is here, misplaced because my initial issue was the absence of development tools & libs.That was solved but following the tutorial on this site. I know it says Ubuntu, but the method worked for me also on Mandriva and Fedora so I was thinking it would help in openSuse as well.
However, in openSuse I have no networking devices when I look in the list (not even a loopback interface or my onboard Realtek LAN). Could someone maybe help me in doing a proper installation (maybe help me with a change to that tutorial to make it work on openSuse?).

I have just installed Fedora 10 on a Dell Inspiron 530. I was delighted to see on the very first boot into the system that my Edimax RT73 USB stick was recognised by the system as it was offering a selection of wireless networks to connect to. But oddly, my own network wasn't listed there. I created a new network and entered the network id manually. Once it was in the list, I checked the radio button and saw a message that I am connected to my network. But after a few seconds the network icon disappeared.
I rebooted the system and again went through the same process with the icon disappearing.
I have an Edimax wireless access point with DHCP enabled. The security is WPA2 Personal with AES.
Vista is also dual booting on the same machine and working fine.

I'm going round in circles with this as I'm just not very good at using the command line in Ubuntu. I've bought an Edimax EW-7811Un nano USB wifi adapter, and I'm really cheesed off at the moment because I can't get it to work on my laptop. I've got Ubuntu 10.04 on it. I really want this tiny dongle to work with my computer. Ubuntu is much fats than Windows, and I use it all the time, but my current wifi donlge is an old big monstrosity!

The issue is that after a while the lan side doesn't work any more (I don't know whether the wan side still works, but I assume it doesn't)
First we had BR6214K for which the transformator turned out to be broken (at least after a few years it gave 7 instead of 12 volt), only have it's replacement die shortly after. But the issue since the beginning was the network disconnecting every two to three days. Restarting the router solved the problem almost every time.
Now we have the same issue with a brand new BR6226n. This time the disconnection occurs almost every day. Restarting the router has so far worked every time.
Is this more likely to be a router or a computer issue (maybe a broken network card in one of the computers)?

Got an Edimax 7717un USB dongle for my Acer aspire 6930 (built-in WiFi is broken). It finds access point OK, but fails to setup with DHCP. If I put in manual IP config, I can ping OK, but I cannot browse web (or even my router's setup page). I get same behaviour on a home brew desktop.
With manual IP config, ping to my router works fine (and very fast, as does ping to 2 or 3 internet web sites. I can traceroute to internet web sites OK as well. With web browsing, if I wait a few minutes some bits of the page may arrive. With connection set to DHCP, Wicd shows WiFi connecting OK, but DHCP setup times out.

I have Maverick Meerkat running perfectly on my laptop and have loaded as dual boot onto my old XP pc as well, I'm quite a newbie and working my way through Ubuntu for Non Geeks.
Problem - apparently this PCI card - Edimax wireless N PCI 7727in card is supposed to work out of the box, it came with the Ralink drivers for Ubuntu RT2860.
the network manager finds the homehub and tries to connect but just continually tries and never actually does it, the card works fine with XP so i know it's not faulty.
if it was a driver fault would the card be working at all? would it try to find the network manager?
I bought this card as previously i was using a Dlink DWA-140 and gave up trying to make it work, this card is advertised as Linux compatible in the Ubuntu forums list and on the card.

Finally took the plunge and upgraded my ubuntu studio to karmic from jaunty. I seem to be experiencing a problem many have, being that my wifi card (edimax) which worked on my previous distro is now not working at all. I've done a lot of research and found the problem seems to mainly be with broadcom cards, and have tried a number of things relating to those that have worked for others, with no luck.
My problem seems to be not that the drivers wont activate or anything like that, my problem is that under hardware drivers nothing appears at all. I have no drivers present, where most people are talking of 3. i have not found anyone else with this problem. My problem is compounded in addition by not being about to use a wire connection at all.

I have just upgraded to 11.04 from an earlier version and most things are working better, if a little slower. Had to remove pulse audio to get any sound. Wifi with Edimax 54G Pcmcia card used to work fully, but now only works on mains, not on battery.Suspected power management but iwconfig shows it is off.Dmesg revealed that the driver had crashed in rt61pci.
Code:

[ 452.171559] IP: [<e0a441df>] rt61pci_config+0x1f/0x180 [rt61pci]

In system log i get:

It seams like a physical hardware problem but i cant find any physical fault on the card itself.

After purchasing few wifi-usb-dongles for my jaunty and lost many hours, i had no success in bringing them to operate as master or ad-hoc.The devices were Belkin, Level1, and a TP-Link 620 Though the Belkin could work as ad-hoc, but very often disconnects due to buffers issue (though I couldn't build the zd1211b driver for jaunty and it seems that no one can really help with that).
Now I would like to consult with you ahead regarding new potential devices, whether you know it operates as master mode or ad-hoc mode under jaunty (9.04)?
My concerns are regarding:
1. Edimax EW-7318UG
2. Edimax EW-7318USg
3. Edimax EW-7711UMN
4. Edimax EW-7711UTN
5. Edimax EW-7311USN
6. Edimax EW-7717 nMax
7. Edimax EW-7718 nMax

Just installed Ubuntu Studio 10.04 and everything seems to be working nicely except I have no networking.
The card does not appear in the Network Settings GUI. The only 3 tabs I have are General, DNS, and Hosts.
A screen grab is attached.
I'm a long time Windows user trying out some of the best Linux creative apps I can find. So, Ubuntu Studio was a no brainer. I checked the manufacturer's site for linux drivers and they are available, but I don't know how current. (Edimax site, not RaLink's site.) I opened the file and it looks like it needs to be compiled and installed to work. Something I know almost nothing about. The card is listed as supported in this forum for Ubuntu 9x but I can't find information about it for 10.04
PS. I have no networking on the system but I can transfer files via USB flash drives if needed.
Some System info:
Code:
1 ) Machine Brand and Model (PC/Laptop): Dell Precision 650
2 ) Wireless Brand, Model and Wireless Chipset: 03:0c.0 Network controller: RaLink RT2561/RT61 802.11g PCI
3 ) check interface: robert@ubuntu:~$ ifconfig

I've currently got the beta of fedora 12 installed, hope to upgrade that once the final release comes out. I'm having so many problems getting wireless to work. I've got a edimax ew-7711utn wireless adaptor. It doesn't work. Really what I want is to take it back and get a wireless card that will work.

I have just purchased an Edimax EW-7128g with Ralink RT61 chip and physically installed it in a system running CentOS 5.2. Trying to follow the installation instructions, I get the following:
[root@webtest Module]# make all
make -C /lib/modules/2.6.18-92.el5/build SUBDIRS=/root/drivers/2007_1210_RT61_Linux_STA_v1.1.2.0/Module modules
make: *** /lib/modules/2.6.18-92.el5/build: No such file or directory. Stop.
make: *** [all] Error 2
The problem is that although /lib/modules/2.6.18-92.el5/build exists, it appears to be a link:
[root@webtest Module]# ls -l /lib/modules/2.6.18-92.el5/build

I have just installed an Edimax EW-7612PIn PCI-E Wifi card which has an RTL8192SE chipset. This chipset is not supported under current F15 kernels so I have installed the driver and firmware from source and have that working fine. The driver can see the card and I can issue 'iwconfig' commands successfully enough to see my Wifi network.
The problem I have is that I don't understand the relationship between iwconfig and wpa_supplicatant and as I'm running a headless F15 server I cannot use the NetworkManager GUI to help me. I should also note that the Wifi network is using WPA2-Personal encryption.
This is what I have done:
Configured /etc/sysconfig/network-scripts/ifcfg-wlan0 with what I think are reasonable values (based on google searches), including the ESSID, TYPE as Wireless, etc.
Configured /etc/wpa_supplicant/wpa_supplicant.conf, including using the key value returned from wpa_passphrase.
Arranged for wpa_supplicant to run from boot, using chkconfig.
However when I run 'ifconfig wlan0 up' I get the error message 'link is not ready' and indeed looking at the output from 'iwconfig wlan0' there are no configured values. I also understand that some values are configured by iwconfig and others by wpa_supplicant, however it's not clear what.
How do I permanently set iwconfig values?
How do I configure wpa_supplicant?

Hi I have istalled a D-Link wireless adaptor - with the help of this forum.
It is up and running - the light flashes and lsusb identifies it correctly, so does iwconfig.
I can, however, not connect to the network, and I noticed the following errors on boot up.
Trigering udev events: /sbin/udevadm trigger -- type: failed /etc/rc.d/rc.M: wlan0 Error for wireless request; "Set Nickname" (8BIC) information; "Any ESSID" Set failed on device wlan0; operation not supported.
Lower down I get
Starting rt2870 drivers . . . /etc/rc.d/rc.inet1: wlan0 information "Any ESSID"
Error for wireless request "Set Nickname" (8BIC) set failed on device wlan0 : Operation not supported
I have on two occassions seen sugstions to use wicd, but how do I use that?

I just installed Ubuntu 11.04. The drive was formatted when I installed so it's 100% Ubuntu. The only major problem I have encountered is that Ubuntu will not recognize my SD cards. I really need to access these cards, all my film footage is on there. I think the internal SD card reader (If such a thing exists) would have been deleted during the installation process. I am a greenthumb to Ubuntu and have never used it before so I am rather stuck...

i had an old Dell collecting dust and i've wanted to dive into Linux so i bought a wireless card for it. It's an Edimax EW-7128G, the reason i bought it is because there were multiple positive reviews on how well it works in linux. Ok, so i don't know linux at all. I installed Ubuntu to learn. I installed the card and as far i can see it's not working. It came with a disc with linux drivers yet i don't know how to go about using them.

I have a backup HDD with a different distro for my laptop and i can boot into it via external usb or if swapped into the laptop. This HDD/install in question is debian testing and was working fine, the issue arose suddenly. I was first suspecting a failure of hardware somewhere on the motherboard, but the hdd i was using with an external usb adapter also works when installed into the machine. also, the HDD is recognized once i have booted using the external HDD and distro, but it is not recognized by the bios. so i dunno, my first guess is something became corrupt within the testing install, but i guess its also possible that there is some wrong with the HDD but thats not immediately apparent as all the data is still accessible.
Should also note that the HDD with testing on it is also recognized when connected via the external usb adapter, while booted from alternative distro/HDD.
Also. just tried this, but i can get the testing HDD/disto to boot if connected externally. it was going pretty quick, but there i did catch a line about a corrupt filesystem. any commands to run to see what might be going on?? log files to look at?

I bought this Wireless N USB dongle Edimaxx EW-7811Un today and it works fine in Windows. But when I plug it into my Ubuntu Netbook, nothing happens? I'm guessing this is a driver issue and there is a driver available on their website but I have no idea what to do with it as I have never manually installed a Linux driver before. I tried looking up some tutorials but all the methods seem completely different between specific hardware. The driver is available here : [URL]

I bought a wireless card as stated because it said Linux compatible on it.
I found out on another blog that I needed to blacklist the following:
blacklist rt2x00usb
blacklist rt2x00lib
blacklist rt2800usb
Since then the wireless on my Ubuntu finds a couple of networks, amongst them my wireless network that I am trying to connect. When I enter the Password (which I enter correctly btw) then it tries to connect, but then stops after about 30 seconds.
