Ubuntu Networking :: T22 With Edimax PCMCIA Disconnects On Switch To Battery?
Jun 18, 2011
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:
[ 452.171536] BUG: unable to handle kernel NULL pointer dereference at (null)
[ 452.171559] IP: [<e0a441df>] rt61pci_config+0x1f/0x180 [rt61pci]

I've got a Toshiba Satellite with the Realtek rtl8188ce network card. I've successfully downloaded, compiled and installed the driver and it works great except when running the machine on battery power when it constantly disconnects, like every minute or two.

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.

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.

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.

In system log i get:

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

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.

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

I have a WPC100 linksys network card. I have ubuntu 11.04 installed. My laptop is a D610.
I have done a LOT of google searching and not seeing any solutions on how to successfully get it working.
I have tried the ndiswrapper and it does install the driver but then says "no hardware present".
I have also blacklisted the broadcom drivers.
I am coming to the conclusion that it will never be possible to get the WPC100 to work. (note I also have been to the support page and do not see it there. )

some time ago I installed 8.10 on my x20 thinkpad. I at the time was trying to get it going on a Netgear WG511 v2 card. I was eventually successful in getting it going with ndiswrapper and all has been happy until...
I decided to give my laptop to an elderly friend for his first computer. He is living in a location where (for a variety of reasons) he is sharing a network connection to the internet with a few people. The protocol there WPA2 TKIP (IIRC) and no matter what the bloody thing won't connect. Here at home I run a different setup so its not a big deal
So, I thought I'd try another card to get it going there. I chose a "Aironet" card (badged a Dell 4800 LT) and tried to install this on 8.10
I expected it would install out of the box, but did not "seem to".
I followed the steps on this page, but still it won't connect to my WiFi at home (which I am using to connect to with this x31 thinkpad)
I am using Network Management Applet 0.70 and this works fine with the Netgear card, even showing all the local networks it finds.
When I plug in the Dell card it blinks the activity light and the status light in seemingly meaningful ways, but nothing seems to connect and I find nothing listed in the Network Applet.
I suspect that the OS is discovering the card as when doing an iwconfig I find two entries that would be that card:
eth1 and wifi0
iwlist scan returns:
which makes me think two interfaces are taking the same hardware...
iwconfig returns idential results for eth1 and wifi0

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
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0

Just completed installing Xubuntu 9.04 to my old Dell Latitude CPi and it seems to be working quite well. However I need to assign interface eth0 to my pcmcia network card (as opposed to eth1 or eth2). I have two cards to try out. One of them comes up as eth1 and the other as eth2. There is no eth0 listed when I run ifconfig -a. There is no built-in network cards on the laptop, so I don't know why it won't assign eth0 to either of the cards.
how to assign eth0 to either of the two PCMCIA network cards.

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:

I just purchased a RALINK WIRELESS G PCMCIA WIFI CARD VISTA/LINUX (UBUNTU).
It is supposed to be UBUNTU plug and play out of the box with no driver downloads needed.
I installed it but could not find a way to search the active Wi-Fi networks available like on my Actiontec card on windows xp. The wireless router/ethernet I have is an Actiontec setup for Qwest-DSL and Actiontec is the name of the wireless network.
Strangely I tried to choose setup a "new network" and entered Actiontec as the network name and it found the network and said it was connected to it. However the internet still is not working?
