Ubuntu Networking :: Difference Between PCMCIA And USB Adapters?
Jan 9, 2010
I am planning to buy a wireless device that supports both monitor mode and packet injection options for my project work..I came across this site while browsing
http://airodump.net/wifi-hardware-monitor-applications/
Is there any advantage of using USB Wifi Adapters over PCMCIA cards??your suggestion/experience in choosing a device in that link or recommend any other device?

I am in the market for a decent USB Wireless Adapter for Ubuntu 10.10 I just wondered what USB adapters everyone is using? Just hoping to get an idea of the better ones that people use.

I have a Netgear WG111T USB and a Edimax EW-7711UAn USB.
I have the latest version of ubuntu.
I have installed ndiswrapper, and loaded the windows drivers in for the netgear, and it will show up in iwconfig but wont connect to anything, I got rid of network manager and installed wicd as I heard that may solve the problem, to no avail.
The Edimax one, I got because I read it worked straight out of the box, but looking into it apparently i need to compile the firmware from ralinks website, but I get errors with that.
Im not too fussed what one I use as long as I get a wireless connection, currently i have it connected to my laptop through a cable and bridging the connections.
If I type in iwconfig with the edimax:

iwconfig with the netgear:

I'm in a spot where my wireless access is about 200 ft from my computer so I bought a tl-wn721 adapter. I have already gotten the drivers for it but somehow I am still stuck with my wireless adapter built in to my sony vaio sz220 (yeah I know it's old...that's why I run ubuntu). So how do I change wireless adapters? The system does say that the realtek drivers associated with the 721 adapter are in use and enabled but in Win 7 I have much higher signal than what is currently displayed. Usually it's somewhere in the high 80 or 90s. Now it's hard to even get 70 and that's how I know that I'm on my built in adapter. I ran lspci -nn and this was my output. I might just not be searching for the right thing. BTW I'm running 10.04 LTS.
00:00.0 Host bridge [0600]: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub [8086:27a0] (rev 03)
00:01.0 PCI bridge [0604]: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express PCI Express Root Port [8086:27a1] (rev 03)
[Code]...
Like some others I have found people are having problems with network manager from time to time. It seems that wicd is the solution. Will this work with ubuntu 10.04?

I know theres a thread for this for fc9 but thats probably kind of outdated now. So I am trying to set up a wireless connection for a pc in my bedroom and just want something that will work out of the box.

Running Fedora 13 and have it working great acting as my firewall/router/samba server etc. The problem is the connection is shared by a fair number of us and the ISP is getting annoyed with the amount of torrent traffic. One of us has access to a wireless network and we'd like to figure out how to route some of the traffic through that without having to disconnect from the current network. I put a wireless card in the fedora box and can connect to the wireless but then it messes up the current network and pretty much nothing works.
At the least if I could run a torrent client (e.g. ktorrent or whatever) on the Linux box and have it download through the wireless card on tcp port XXXXX I would be happy. The torrent client and those tcp/udp ports can be dedicated to that wireless card, the rest of the network doesn't need to get involved if that makes things simpler. Not looking for a step by step tutorial, just an explanation of what needs to be done and a shove in the right direction. My experience is limited to single WAN connections up to this point.

I have been searching the forums for quite a while, to add extra Loopback adapter in Centos 5.1, but no success! Could you please suggest me the steps? in Windows, it is quite easy to add as many adapters as you want. wondering, if this is even possible in Linux? I have to run GNS3/Dynamips for router emulation and bind those Loopback adapters to virtual routers!

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 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 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?

I intend to attach WLAN PCMCIA card to my embedded system to connect to a wireless network. However, my embedded system uses a strangs OS that not supports the card driver. I think that I can investigate on how Ubuntu control the card to find out the way to control it in my system. The WLAN PCMCIA card that I can buy is:TP-Link TL-WN510G,Linksys WPC54GSCan any one tell me, how can I have the source code of WLAN PCMCIA driver and how can I find out the way Ubuntu control this card?

I'm trying to install two devices...one at a time. o far I've had zero luck with either.
1. ViewSonic VS10259 PCMCIA Wireless 802.11G PC Card Adapter.
2. Broadcom BCM94306MP REV 4 Internal Wireless Adapter.
I can't get either of these installed on an old Dell Inspiron 8500. I'm really an absolute beginner with this...I've installed the newest Ubuntu on this machine and am trying to get it to connect to the internet, but am clueless. Sorry if this should be posted in absolute beginner. Don't want to double-post.

I'm using a Kohjinsha SR6 and trialling the ubuntu 9.10 netbook remix from a USB stick before taking the plunge. I have an Emobile D01NX adapter for internet, but I simply can't get it to work even though e-mobile is in the Japan mobile broadband options in network connections (maybe for some of their USB adapters?).
running lspcmcia -v gives:
Socket 0 Bridge: [yenta_cardbus] (bus ID: 0000:02:06.0)
Configuration: state: on ready: unknown
Voltage: 3.3V Vcc: 3.3V Vpp: 3.3V
[Code].....
one thing that's crossed my mind is that I haven't got persistence on my usb drive, would that be likely to affect anything? As I understand it that just means everything I do needs to be re-done when I reboot right?
I looked up this issue on the Japanese Ubuntu forums (here) and what I gather is that there is some sort of technical issue with the translation chip (Elan VMB5000?) but that the Sharp Zaurus (link), which runs on a linux variant, has a driver out for my specific device (here). This may be the answer I'm looking for, but unfortunately my linux ability is largely limited to using the GUI and a few basic text commands so installing or modifying the files is way beyond me.

I finally got around to trying Ubuntu 10.04 on a "decommissioned" Dell Inspiron 8100 1.2Ghz P3 512MB RAM 40GB HD... and Ubuntu is absolutely AMAZING compared to Windows! I'm a Mac guy and honestly Ubuntu gives 90% of the Mac OS GUI and 0% of the "brain damage" of WinBLOWS...
The only thing missing in this laptop is WiFi which I want to do via one of the PCMCIA slots since the mini-PCI is a combo 10/100 network + v.90 modem card... and I need to keep the Ethernet port and fax modem capabilities.
What are the best "Plug n Play" PCMCIA WiFi cards for our "G" and "N" WPA2 ONLY Airport Express WiFi network? I'm new to Linux so I'd really like to avoid editing and replacing system files and drivers if possible to get a PCMCIA card working. I'd also like a card that works in WinXP Pro SP3 since this laptop is dual boot capable.

Any opinions on which of the PCMCIA wireless cards work the best out of the box? I currently have a USB wireless adapter but want to get rid of it and use my PCI slot on the laptop. I am currently running lucid. I would rather not have to mess around with NDISWRAPPER again, something that has a native linux driver would be great.

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]

Older laptop I just upgraded to FC13. I would like to use a Dlink DWL-650 pcmcia card. The system sees it.
#iwlist wlan0 scanning
Cell 01, mac, chan, freq and everything else for my base router
Cell 02, same thing for my extender unit
ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr 00:0D:88:AA:AA:AC
inet6 addr: fe80::20d:88ff:feaa:aaac/64 Scope:Link
[Code]...
ifcfg-wlan0 is set for DHCP. Notice above no IP. If ifcfg is given an IP/mask still no IP. So it seems to be up and running, just not accessible.

So here's the thing: I have a mobile broadband pcmcia card that worked just well on jaunty, but as I installed karmic it doesn't work, coz it mounts the card's storage but doesn't recognize the hardware. The help says I need the package 'udev-extras', but there's no such package for karmic and the one for jaunty doesn't work with karmic.

I have a friend with an old, still-working laptop that wants to switch to linux. (Dell Inspiron 7000 PII) I loaded Lubuntu because it's an old machine and has only 512MB of memory. The laptop has no built-in ethernet or wireless. As the title says, he has an EC2T card with it. I've tried to get lubuntu to recognize the card but it's a no-go. I tried the EC2T card on a Windows laptop at my workplace and Windows recognized the card immediately; I was able to surf the web with it.
It looks like at one time it worked with [URL]... and that individual didn't get an answer. Other troubleshooting I've done:I've ran the 'Hardware Drivers' utility and it found no drivers. I tried lspci and the EC2T card isn't listed. I tried a wireless pcmcia card from my workplace and it worked so the laptop's card slot is functioning; lspci does list the wireless card.

I had Ubuntu 8.04 and the D-Link Wireless WNA-1330 PCMCIA card worked just fine. I upgraded to 10.04 and it fails. I can see the network of wireless routers in my neighborhood, but when I try to connect on WEP 40/128bit with my hex key of my router, it tries to connect but can't get a DHCP address. I cannot ping the router in that state, of course. I have two other 10.04 laptops (with built-in wireless) and they connect just fine, as does a Windows Vista laptop. I also tried the pci=noapi item in /boot/grub/menu.lst, but that failed to show any results either. The card lights up like it should, and acts just like it did with 8.04 on the lights, but it doesn't connect. I end up seeing the "Enter your WEP password" dialog again and again unless I hit Cancel.
