USB wireless adapter - interface name keeps changing

I have used different usb wireless (G) adapters with my 12" Powerbook G4.
Each was automatically assigned an interface name (BSD) such as en2, en4.
I recently updated to a Wireless N dongle (D-Link DWA140) which works great with my new Belkin Wireless N router.
I have had a few connection problems where the dongle was named as enNull.
After rebooting and re-entering the ip address via DHCP, I noticed that the same dongle has been renamed each time e.g First as en5 then en6, 7 and 8. It's now called en10
It works fine but is it possible to reset the name/number of this wireless adaptor using something like ifconfig in the shell Or some other way. I understand that en0 is built-in ethernet and en1 is Airport. I have 2 other dongles which are still identified as en 2 and en4. But my current dongle has an inflation problem and I would like to reset it if possible to a lower number.
Is this possible or am I mad to even consider it?
any help welcome.

That is very strange that PCI cards would keep changing names between reboots. Maybe you should investigate that to figure out what's going on. Check the dmesg and journalctl after each reboot and see what the interface is named as. Maybe that will give you some clues as to what "external" program is responsible in naming the interfaces.

[SOLVED] Network interface name keeps changing

My network interface name keeps changing between wlp2s0 and wlan0. This is a real pain, since I never know what name will be generated at boot. Most of the time it's called wlp2s0, so this is what netctl is set up to handle by itself. At boots were wlan0 is generated I have to connect manually.
I've tried making the name static by adding a rule to the /etc/udev/rules.d/10-network.rules. The rule i added was:
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="48:5d:60:7e:64:e9", NAME="wlp2s0"
Wlp2s0 is generated at boot alright, but I still have to connect manually with this solution. As if the "new" wlp2s0 is not recognized as the old one (same MAC). What gives?
This is on an Asus Eee 1001PXD, with the Qualcomm Atheros AR9285.

I've now been able to replicate the issue, and run the command:
journalctl -b
I did find the output:
mai 18 02:30:02 <hostname> systemd-udevd[126]: error changing net interface name wlan0 to wlp2s0: Device or resource busy
I haven't been able to process the whole output yet (I'll continue tomorrow if necessary), but I've found some things that I hope will clearify things. I get similar outputs to the following a lot throughout:
mai 18 02:30:03 <hostname> dhcpcd[237]: wlan0: carrier lost
mai 18 02:30:03 <hostname> dhcpcd[237]: wlan0: waiting for carrier

mai 18 02:30:04 <hostname> systemd[1]: Failed to start Automatic wireless network connection using netctl profiles.

mai 18 02:30:04 <hostname> systemd[1]: Starting Network.
mai 18 02:30:04 <hostname> systemd[1]: Reached target Network.
EDIT:
I see now that this is later in time, so that's not so strange after all. I'll look some more.
EDIT2:
The error code that a name change i impossible is the first time the term 'wlan0' occurs in the log. However there's a line much earlier that talks about wlp2s0:
mai 18 02:29:59 <hostname> systemd[1]: Expecting device sys-subsystem-net-devices-wlp2s0.device...
But as I said, if this information doesn't help, I'll have a closer look at the output tomorrow. Getting late here in Norway now.

My usb wireless adapter keeps disconnecting

So, I just bought this TP-Link TL-WMN721N 150mbps wireless adapter, and it has this issue. It keeps disconnecting, all the time, i've downloaded the latest drivers and i'm pretty sure it's not a malware problem, also tried connecting to different usb ports.
Any guesses?

Hi，
You can also temporarily turn off your anti-virus software, since some anti-virus might not recognize the new component installed.
I noticed that you've had the latest driver, did you get the driver by manually viewing the device manufacture website to look for the latest version?
This issue can also be caused by incompatibility, Please make sure the usb wireless adapter is compatible with your Windows version.
Please also reinstall the usb controllers as a test
First, please disconnect all USB devices and then perform the following steps:
1) In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".
2) Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".
Then, restart your computer and your windws will reinstall all USB controllers automatically.

Issues with usb wireless adapter

Hi
Please excuse my ignorance.
I have an imac (about 2 years old) with a built in airport card. I am trying to use a usb wireless adapter. It has a realtek rtl8187. we have a wifi network here that works with my pc using this adapter but i cant get it to work on the mac. You have to sling the adapter on the window sill but it picks it up fine.
I have installed the supplied software (obviously the mac one!) and it installs the software and driver. After i have restarted, and plug the thing in, it tells me to turn on my wlan card on the supplied software?? It shows up in the listing on network settings as ethernet adapter ((null)). I cannot find any setting to turn on my wireless card, i thought that was airport?
The airport picks up the network but the signal is too weak to connect, hence the adapter with a bit more guts....
I have this beautiful mac, colecting dust and am having to use a pc!
If i connect the usb adapter without installing the software, it constantly has a box popping up in network settings saying that an external device has changed settings! it doesnt stop doing it, until you delete the location...
Can anyone help? I may be being thick and dont have a wlan card or something or airport will not allow me to use this thing. I only just started getting into macs when i moved to spain, where it has sat colecting dust for 3 months.
I would appreciate any advice.
Thanks
Richard

TNHusker, welcome to the forum.
Cisco makes a router that is good for two-story homes. I have used it for several years. My router / hotspot is on the second floor and my Blu-ray player and laptop are on the first floor. Both work extremely well with the router. They also make a USB, AM10, that works very nicely with a desktop without a wireless card.
I have had a few problems with both, but have always been helped successfully by Cisco Customer Service. They are very good.

Can I use a USB wireless adapter with my iMac G4 Flat Panel (it has no Airport card).

I have just salvaged an iMac G4 15-inch Flat Panel from the skip and now have it running Mac OS X Tiger 10,4. It has a 700mhz cpu, 80Gb hard drive and 512mb of Ram. No airport card is fitted so I was wondering if a USB wireless adapter could be used instead. I have a Belkin F5D8055ea USB wireless adapter fitted and the system recognises the device, this is as far as I have got as I am a complete novice on Apple/Mac machines. Anyone any ideas please?

If the device is recognised, see if you can located your wi-fi network using Airport Utility.

MacBook Computer Name Keeps Changing

Recently my Mac computer name keeps changing. It's the normal name, but with a number at the end that keeps incrementing. How can I stop this?
I'm not sure if it's something to do with the fact I had a partition for the public OS X Yosemite, which I have now deleted.
Any ideas? Thanks.

I was having the same problem for awhile, even contacted support so they could screen share and see what I meant.
What I ended up doing was correcting the name and then unchecking all the boxes in Sharing. Open up Airport Utility and reset the router (basically I changed my password only because that's the easiest way to make it update). Go back into Sharing and recheck the sharing options that you had previously. Viola!
So far it's been a week now and my computer name has not changed. Hope this helps

Will airport work with a simple USB wireless adapter?

I'm considering setting my folks up with one or maybe two airports for wireless audio through their house. They don't have any wireless gear at the moment. Will it be ok to buy a cheap USB wireless adapter for their PC to transmit to the airports?
I'm considering this one: http://www.ebuyer.com/product/107691
My worry is that it might not send a strong enough signal. What do you reckon?
thanks!

I don't have first-hand knowledge of this particular USB wireless adapter, but it should be compatible with the AirPort base stations, as it is 802.11b/g-compliant and supports both WEP & WPA encryption.

IPOD and USB Wireless Adapter Fighting!

I've got a Motorola USB Wireless Ethernet Adapter hooked up to my Dell desktop running XP. When I put my iPod in it's cradle, it disconnects the wireless. I've tried moving the iPod onto the other USB bus, but I keep getting the same problem.
Any suggestions?

Hi Emily & welcome to the discussions:
My first move would be to switch from usb to firewire connection. Much more stable. If your Dell does not have firewire, I would opt for the Adaptec Firewire 4300 card that is so highly recommended in various threads here.
I have wireless usb devices working along side my firewire connection for the pod and have no problems.
Good luck,
Larry

Why does the local network and computer name keep changing?

After upgrading to Yosemit the local network name and computername on my iMAC keep changes link:
Mycomputer-1
Mycomputer-2
Mycomputer-3
Why?
I have tried to change it back in sharing and network locations.
Is this also the reason the my iPhone cannot find my iPhone often cannot find my iMac when I will sync it? Then I have to restart the iPhone and iTunes on the computer. This happens very very often.
Maybe it also linked to these errors which the log is full of - many every minute:

I think the is some bug/clash between bonjour and other network protocols. That is only a guess.

After resetting the computer name and local host name to the correct name without the number I also shotdown my iMac, my AppleTV, my iPhone, my iPad and then rebooted my Airport/Time capsule it seemed to work at least for several days. But yesterday I discovered that my Apple TV now also has changed name to Apple TV (2).
I logged into iCloud.com to see my devices and here it was really wired. My Apple TV was called Apple TV (2) and my iMac also had (2) after the name. Then I checked it on the iMac but here it was correct! Why can it have one name on the iCloud and another on the computer.
I restarted both the iMac, Apple TV and Airport Time capsule then everything was correct also on iCloud.com.
But today the iMac was called the name (2) again on the iMac. And now the local host name also had -2 after the name. It has not always been both names that has changed. That is really wired. And today Wifi was not working on the iMac after wake from sleep. I changed the name back and rebooted again also the Airport Time capsule. Now it is working again.
The log is still full of this messages:

The name is not the only problem. Often itunes will not find my iPhone and iPad. Then i need to close iTunes and restart the iPhone and iPad then it works for some time.
And the iPhone and AppleTV will not always wake the iMac from sleep. I am wondering if the is linked to the changing of name.
I have seen by googling that it can be related to a sleep proxy problem so it seems like that here is two devices on the net with the same name that is why name is changing, but to know this do not help me to solve the problem. I have also seen all the suggestion to turn almost every services off on the computer, but again I it is not a solution and I have the iMac and devises to use the functionality not to shot everything down. So I do not really understand people saying turn off itunes, turn off blueboth, and turn off this and that.
Apple must soon come with a real solution. We are really many people have these problem since we upgraded to Yosemite and iOS 8.
I have also listed some of the iTunes errors from the log below:

Having trouble setting up Ralink USB wireless adapter

Hi all,
I recently bought a usb adapter for my G3 which is running Tiger. Downloaded the most recent driver from the Ralink website and it appeared to install fine, however when I double click on the 'Wireless Utility' app to configure the adapter it won't launch.
It doesn't bob in the system tray, it just does nothing. The adapter itself is recognised and shows up in the profiler but I can't use it as I can't put in the WEP password or anything.
So far what I have done is repaired the disk permissions and tried reinstalling the driver several times.
Does anyone have any suggestions?
Are there any alternative programs I could use to configure the adapter with? When I open the network panel it shows up as 'en2', but then if I click 'assist me' the airport option is greyed out.

Not sure what else you can try. The answer may lie out there on the internet somewhere if you could just happen upon it during a search. Hope something turns up for you.
PS I vaguely remember that when I installed the software for my Macpower Newer Tech USB wireless device there were instructions that were very specific about the installation. They said it was very important to either install all the software first and then connect the USB device or vice versa. I can't remember which way it was. Maybe you could give it one more shot and uninstall everything, disconnect your USB device and start over from scratch. I'd try installing all the drivers before connecting the device.

Sequence and clip name keeps changing... Why ? Solutions ?

The sequence and clip name on a particular project keeps changing. It usually takes the name of of an audio file. Deleting the preferences, opening the timeline in a new project, making it offline and reconnecting it again, et. all doesn't help ? What is causing this ? HELP
Mac Pro Quad core
Memory 8GB
Storage - XSAN
FCP version 7.0
OS X version 10.5.8
Quicktime 10 & 7.66 both installed
Anyone has a solution for this....
Jp

I made the sequence off line and save it as a new project. Then deleted the preferences and opened the project..... reconnected the media. Most of the clips showed the correct clip name and the sequence name also didn't change. But a few audio tracks still had the old problem....
Thanks for the reply.... haven't updated yet..

Network share name keeps changing

I have setup my eMac to have the network share name eMac but it keeps changing into +eMac (2)+ does anyone know why?

well I do, but a short while later.
or some weeks or even month later, I can do it again.
this is a problem because I need to connect to it from my server.
the server is a Dell PowerEdge 1650 (I know, old, but it was cheap and it does the trick) which is running Linux Ubuntu Server 9.10 "Karmic Koala", since it's a server I did not install a DE(desktop environment) so I need to use the bash or shell (depending on what I do, since it has both)
how I connect it like this (on the sever):
+mount -t nfs "emac.local:/dev/macintosh HD" /storage/nfs/emac/+
the problem here: I use a DHCP, with DHCP reservation.
since I use DHCP reservation the IP should not change.
but the DHCP reservation doesn't really work correctly,
because of this, if my mac is offline (A.K.A off, I never disconnect it), the IP is in the pool, and thus can be assigned to a other computer.
since the IP may change depending on if it is on at a given time.
I need a way to always successfully identify my emac.
for this I use the network name.
and now it changes too!
which means that in order to find it I need to know if it still has the same network name, or what it's IP is.
I can find the IP from a web browser since it's my router who is my DHCP.
but the server doesn't have one.
so I'd have to use a other computer, since the router doesn't allow SSH/TELNET connections.

Usb wireless adapter for solaris 10 on sparc platform

Hi,
First and foremost, I hope that this stands in the right place.
I need to configure my Sun Fire V240 to connect to my wireless network (wifi).
Just wondering do we have the list of usb wifi adapter (and driver) that can work in Solaris 10 on Sparc platform?
Or, can I have the list of Solaris supported PCI wifi adapter and driver? It would be great if instruction included.
Thanks in advance.

Hi guys, I also had this situation and since I was not able to convert the package to a datastream, I downloaded it from http: //www. sunfreeware. com/mozilla .html
They also provide some readme files that can be of help.
Once you have the datastream package you can install using pkgadd utility.

Group names keep changing ..

I am creating a report will mulitple queries ..
i notice that the report builder keeps changing the
group name ..
a) how does report assign gruop name and
how can i change in a way report doesnt alter it ..
deepa

Hi Deepa,
Reports Builder will assign a default name to a group inside the data model when you write the query, but once a name has been assigned to a group, it should not keep changing the group's name.
For your own custom name, double click on the group heading in the data model, and type your desired name in the "Name" field of the Property Inspector that comes up. It should not change thereafter.

TS3171 IO'S and bus names keep changing from session to session

My IO'S keep changing there names back to original factory names after I change names on bus and input output they do not save from session to session .i am in 9.21 ver and using lion any help would be great

To recap (correct me if I'm wrong), two things have to happen for session sharing to work: 1. the session must be passed in a cookie (the same cookie used by appls sharing the session), and 2. the appls must use the same authentication.One solution is for both/all participating applications to use an authentication scheme based on our built-in session management mechanisms that use a cookie in conjunction with our internal sessions table. The schemes may differ in most other repects, e.g., one might use LDAP and the other your own user tables to authenticate. N.B., the no-authentication (DATABASE) scheme does not use a cookie. Another solution is for you to implement your own session management infrastructure. With that, the only constraint on session sharing between applications is that a) the applications must belong to the same workspace, and b) sessions already "registered" in the internal sessions table with an authenticated username may not be used by a different authenticated user.
Optionally, if you want either of the appls to have public access you make the pages public.Yes.
