I have 2 network adapter, 1 wireless and 1 wired. Both are connected to different network. Whenever I plugin the cable, wireless stop working. I need to get both working simultaneously. Do I need to do any settings to make both work?
View 1 RepliesI just installed Ubuntu 10.10. Everything works fine, except wireless. Wireless works fine for a while (I am right now using it) but then it loses all networks and I have to shutdown and then start Ubuntu again to get wireless network again.
I have MSI laptop with Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)
yesterday I let the update manager install a whole bunch of updates for my 10.04 install on my MSI Notebook ER710. My wireless was just working peachy until then (with the madwifi drivers), but after the update, no more... I checked the madwifi, tried a new make, but nothing worked.
So, after reading somewhere that 10.10 had less issues with wireless I decided to upgrade to 10.10 in the hope that that would solve my problem.
Well, partly it did, as in, according to my system I've got a wireless again and this morning even, it was able to see wireless networks! Unfortunately I couldn't connect to mine, although the key was correct. At some point I lost the ability to see wireless networks again. I tried wicd too, but no luck their either. It recognizes my card but can't see any networks.
here is all the info:

I buy a new usb network adapter (Through DX), when I try to use it in ubuntu or BackTrack4 Final it is working, and connecting networks even with WPA encryption. But after few minuts it stops working totally. It is showing that I'm connected to the AP but web sites do not respond.
Notes:
- I have another PCI Wireless adapter which works fine.
- The problematic adapter works great on windows.
- A driver CD came with it, including a linux driver which I wasn't succesfully installed.
- A BackTrack3 Disc came with it, claming by the instructions that the adapter will work with it. I didn't try it because i have backtrack 4 final.
It took me dozens of surfing the web hours, and too many restarts,
I am trying to connect my desktop to my laptop over a non-internet connected LAN, but when i enable the LAN connection on my desktop (the one with the wireless) its internet stops working.
it is a very similar problem to this except that i am using ubuntu for the machine with the two connections.
right now i have my wireless on the 192.168.1.* address space, while the LAN is to be on 192.168.5.*
note: my goal is not to share internet with my laptop, just be able to connect to it and the internet at the same time.
desktop: ubuntu 9.10 , wireless and LAN
laptop: windows xp, LAN only
I normally use a cable to connect to the Internet, but I also use the wireless network regularly. So I'd like Ubuntu to automatically use the wired connection except when there isn't any.
I also have the unlock keyring problem (because of auto login and wireless Internet), does anyone know a solution to that problem? (It's quite disturbing to get that window each time you start the pc even if you aren't going to use wireless Internet)
system:
Ubuntu 10.04, auto login, Intel Core 2 Quad Mobile Q9000, ATI HD 4670, 4 GB RAM, Broadcom NetLink BCM5784M Gigabit Ethernet PCIe, Intel Wireless WiFi Link 5100
I have a wireless connection with static ip 192.168.10.150 to connect to Internet through a modem / router ADSL ip Lan 192.168.10.1. I connect with no problems. I have a wired network in the office 172.16.17.0/24 to work with the servers. the router is 172.16.17.1, my connection eth0 with static ip 172.16.17.150 work, but Internet by Internet nothing. If i disconnect the cable i have Internet from wireless. ?? What i have to do to ,to received internet by wireless and be connected ate same time to my wired network by eth0 too.
all routers have DHCP active.
I recently installed the vt6656 wireless pci card that came with my zotac motherboard. I can associate with my ap and get an ip address successfully. When I disconnect my ethernet cable, however, my wireless interface stops responding (can't ping it). The box itself is in a place where I don't have a monitor connected to it so I cant see anything since my ssh session gets killed as soon as I disconnect the ethernet cable.
What would be the reason why the ehternet cable being unplugged, disconnects my wifi card as well? Does something get triggered? I did some testing with iptables, blocking the 8080 traffic to the wired interface, and noticed that the 8080 traffic also gets blocked to the wifi ip. I'm afraid that this never worked properly to begin with.
my wireless will simply stop working after each new webpage loads. Whats strange is that it will not disconnect me, and the wireless icon in the top right will continue to show that I am connected to the internet. I am currently tethered to my phone and the internet is working fine. Once If I switch to my regular wireless internet and disonnect and reconnect to my home router then the webpage will load fine only once then after that it will not work again until I disconncet and reconnect again.
This is not a problem for anyone else in my house who all use macs (needless to say they are all very smug about this). Also when I connect to my schools wireless internet there is not a problem. Also restarting my modem and router at home does nothing to solve the problem. Like I said before this just started up about 3 days ago and has baffled me since.

I have a laptop, and the wireless and cable worked fine for a while, but one day, for some odd reason, the wireless and network cable just stopped working. I'd connect to the web, and I would get output using "ifconfig" and the GUI wireless signal. When I hook up the wire, it detects it. However, no matter what I can't load any web pages. The wire does work in another house, and my windows partition utilizes these devices well. Any ideas?Additionally, I am able to log into my wireless router and change configurations, but that's about it :/.
View 2 Replies View RelatedI'm a new user of Ubuntu, so i'm not that familiar with this OS. My wireless network is detected but when I'm entering my 128 bits WEP key, it doesn't connect at all. I have no clue where to start troubleshooting.
Here's some of my specs if that's of any help:
Computer is a Sony Vaio laptop model VGN-SZ370P

The ethernet cable connection used to work before, but I fooled around with some commands and now seems to be disabled...
I recently installed ubuntu on my mom's computer but I can't get the mouse to move trough the touch pad and I suspect the USB is not working either, because I can't get anything to work trough the USB, and the Internet is not working trough the cable, and I think wireless as well. Her computer is an old acer aspire 3000

Using ubuntu 10.10 (pinguy OS) i connected an ethernet cable from my girl's macbook pro to her lenovo ideapad s10-3t to transfer some DS9 episodes onto it. new enough to linux to have not been able to figure out how to access the files on the mac, so i disconnected the ethernet, and the wireless hasn't worked since. tried everything i know, and googling for a while (as well as searching again on this forum) to no avail.
Just before linking the 2 computers via ethernet, the wireless worked fine on the ideapad, always had; but not so after the ethernet connection that did nothing other than apparently kill the wireless. an "lshw -C network" command tells me i have a BCM4313 wireless card, and *-network UNCLAIMED. also, if i launch "install additional drivers", i see that the proprietary driver is not active.
How could merely plugging in an ethernet cable that happened to be conncected to a MBP running OSX.6 do that? and will that happen again? i thought linux was supposed to play real nice with other OS's, so why did a simple file transfer kill my wireless connectivity? i have no access to internet via ethernet cable, so i cannot just download the driver i need now. shouldn't it still be in the computer still? somewhere? is there a simple solution to this, or has the wireless driver been wiped out by plugging in the ethernet? is this a bug that should be reported?
if i would know the terms i could search for it, so bare with my words: i got an old PC, and my ethernet-cables don't fit into its plug (port?). its a little smaller than the usual one. how is it called and what am i looking for (whats the name of the plugs which need to fit, whats the measure. all i could see is male/male and some voodoo stuff like RJ333 <-wrong.

Xubuntu 9.10 on a DELL Inspiron 1150.I have a problem with intermittent dropping of my wireless connection ( see Belkin 7010 thread).Once dropped, the wireless will NOT reconnect (It just sits there saying "connecting" but never does) Same happens if I manually disconnect - I can never re-connect. On rebooting it will reconnect fine & all is well for sometimes 4 hrs.How can I kill all wireless services & restart them without having to reboot the laptop?

View 2 Replies View RelatedUbuntu 9.10. Everything works fine until yesterday when I cannot connect to network. My lan card is Realtek PCI and is present on system (i can read mac address and all settings). In connection manager I was try to set everything manually (IP, netmask, gateway and DNS) or leave automatic - without success. I am connected to router. I don't want to feed "log-hungry" people because how to resolve ubuntu lan problem can help me (not someone who will want to try). I cannot connect manually because there is no option when I click on network icon (I can just uncheck connection, but that's all). I can't even access to my router (from computer with Ubuntu, because I can access from another computer). All logs shows lan card proper. Windows XP on the same computer booted from another HDD works fine.
