Ubuntu Networking :: Wireless And Cable Connection Same Time
Apr 7, 2010
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.
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.
I am running Ubuntu 10.04 and i have some problems with my intel WiFi 5100AGN. After a randoom time i dont have a connection anymore and Ubuntu does not reconnect automattecly. I get an popup with the preinstalled password for my WiFi but for some reason i cant connect to it. I have a pastebin from the dmesg after it happens.: [URL]... It is tottaly randoom time it can happen in 1h and also in 6h.
This is not exactly Ubuntu question but i don't know where else to ask. I'm trying to setup a Wireless Linux router. My ISP provides multicast IPTV. I've got the whole thing setup'ed with igmpproxy and hostpad. On wired connection IPTV works flawlessly, but on wireless connection IPTV glitches badly and router start to time out. My wireless card is DWA-552 I'm using ath9k driver. More info in my post on LinuxQuestions.org Did anyone tried to setup Wireless Router with IPTV?
I've got a Laptop with wireless broadband connection which needs to be connected to a desktop machine so that the internet connection could be shared. Both has got Ubuntu 9.1. I don't have a router or a switch. I just need direct connection with a cross over cable.
I am trying to run a cable from my wireless router over a 75ft cat6 cable to my bedroom. I don't get any connection on my end and I don't have any other ideas. I did setup a m0n0wall box just to try. I got the network led on my server to light up in my room but nothing more than that. Lastly, I tried adding a 5 port switch in my room and then connecting that to my server and nada.
I've been reading too much and understanding too little. What I have: Lucid laptop & desktop. Both have ethernet > hub > internet. What I want: connect them directly by the serial ports so the laptop can access the desktop's drives, and the desktop can be retired from the internet. I've got an old DB-25 null-modem, last used for multiplayer Doom. The laptop's dock has DB-9, so the connections is desktop > null-modem > Belkin DB-25 - DB-9 cable > laptop.
I had hoped this post would get me somewhere:[URL].. No such luck. When I ping 'grin.local', the connection is through the internet. If I disconnect the hub, i cannot ping.
Dunno if there's something more I should do to enable serial connection in Lucid, or if my null-modem is no longer good. I'm also rather curious how "grin.local" manages a connection through my ISP's system. These are DHCP. Shouldn't that have required the full numerical IP?
(It's nothing to do with the hub. Checked that by connecting a third box to the hub. My ISP only hands out two IP. I couldn't ping the third box.)
I have a desktop running Ubuntu 8.04. I installed 10.04 on my laptop. When I mount my desktop music folder on my laptop and transfer files, they now only go at 100-200 KB/s. When I had 9.10 installed, they transferred at 1-2 MB/s.
This is the command I use to mount the directory: sshfs matt@169.254.6.233:/home/matt/Music/ /home/matt/Music/desktop/ Is there any way I can speed it up to get it back to max speed?
I have a strange problem that I cannot diagnose -- slow wifi. About two or three weeks ago, I noticed that my wifi began to slow down dramatically. The problem is the same on my ubuntu laptop and my ipad. But when I connect directly to the router with a network cable, my connection is fine. So it is definitely a problem with the wifi signal itself.
What I have done so far: (1) I checked all of the MAC addresses connected to my wifi. I identified my tivo box, laptop, and ipad. Nothing else.
(2) I used [I]wifi analyzer[I] on my android phone and selected an unused wifi channel (channel 8).
(3) I changed the username/password on my wifi signal. I also changed the password for my router's admin privileges.
(4) I restarted my router and computer. None of this helped.
OS: Maverick Ethernet driver: tested with sky2 an sk98lin This has been driving me crazy for the last few months: if I unplug ethernet cable while my laptop is on reconnecting it sometimes does not bring the connection back.
And once ethernet is gone nothing that I try seems to consistently bring it back. Rebooting, disabling/enabling the driver, disabling/enabling NIC in BIOS, changing driver from sky2 to sk98lin, deleting connection from Network Manager, resetting the router - nothing helps. It seems to come back randomly a few weeks later. Once I used live Ubuntu on a USB stick and ethernet came back not only on a live distro but then when I rebooted also on my main OS. But when I tried that trick next time ethernet was missing in the live distro as well.
Also once I was able to revive ethernet but compiling sk98lin driver, blacklisting sky2 and rebooting. Of course next time doing the same routine did not help. The thing is - ethernet works fine with either sky2 or sk98lin and I can unplug the cable and plug it back in most of the time without any issues. But then every so often - bang and I'm stuck with only wireless until ethernet suddenly starts working again.
how i can use VLANs. as i have red on the web, it is possible to have a switch to allocate ports to a single VLAN. thus splitting subnets on a port allocation. since i have a pc running KVM, it is possible to create multiple subnets for DMZ and LAN. thus my question is - is it possible to have a SINGLE cable connection to a switch that carries TWO subnets? so that i can decide how to distribute then on the pc?
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)

Running 2.6.29-gentoo-r1 on a Sun Ultrasparc 10 with a Sun Happy Meal on eth0 connected directly to my cable modem. Intermittently, with a frequency between a few hours and a few days, I lose internet connectivity. Running ifconfig eth0 indicates all is well and I have a valid IP address but I cannot even ping the cable modem's management address; pings to 127.0.0.1 and eth0's IP address do get a reply but no other address I've tried does. I can 'fix' the problem by issuing
Code:
If I check the CM logs, it appears that it has rebooted itself prior to the loss of connectivity. The strange thing is that the incoming traffic doesn't seem to be affected by this, my PSAD log is full of incoming scans even during the periods when I can't connect to the net. I suspect this is an ISP problem (they own the CM);
Running Gentoo with kernel 2.6.29 on a Sparc Ultra 10. I'm having problems with my cable modem connection failing, so I've added a static route that enables me to log into the modem's diagnostics page at 192.168.100.1 when the connection drops; my /etc/conf.d/net looks like this (with the comment lines removed).
In the right upper corner of your screen,you can see if you have a network connection or not.Most of the time I do not have one according to Networkmanager (?).So I have to enable my wired connection manually.I already tried a lot to change my settings so I would have a network connection at boot,but it doesn't seem to work....Firefox is in Offline modus when I logon..
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?
I'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 My wireless card is from Intel Corporation 82801G (ICH7 Family) USB UHCI Controller
The ethernet cable connection used to work before, but I fooled around with some commands and now seems to be disabled...
When I have video running and the video stops, I see that the connection is destroyed in about 5 seconds, which is what I want. If, rather than stopping the video, I pull the plug, I have seen it take 350 and 380 seconds before the connection is destroyed. Why is there such a large difference in the time to destroy a video connection between stopping the video and pulling the plug on it when using net filter connection tracking? How can I shorten the time for the connection to get destroyed when pulling the plug?
i'm having problems connecting to the internet unless i manually enter the IP info.
automatic DHCP does not work. I'm on a dual boot machine vista/ubuntu 10.04 LTS connecting to the internet through a lynksys wireless g router and a cable modem.
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?
Toshiba A215 laptop Driver is rtl8187 I really need to make the connection constant and non-dropping. I've had opensuse 11.2 since march 7 2010, figured out most of it by lurking and reading threads didn't want to make threads but I really don't know what to do to make this connection stay on. I am posting Terminal commands from when I am both on and offline.
How I attempted to fix this issue myself: I downloaded wireshark, wicd,knetworkmanager. Tried running all of them nothing worked. I went into Yast and switched off networkmanager and went traditional still nothing. Tried adding opendns to traditional. nothing. Went back to NM would get online then after an unknown time I'd lose connection even though NM said i was still connected. Offline running terminal commands from what I read on here in other threads and stickies

Okay so I am a total newb to linux. I installed Ubuntu using Wubi and am trying to figure out how to get my wireless connection working. It occurred to me I may not have the right driver for use with Ubuntu for the wireless connection at my house. I couldn't find anything on the web to help..it appears I have a realtek RTL8102E wireless card in my laptop. I have absolutely no idea how to resolve this situation..I've looked on the web, but everythings pretty confusing. If I could get the wireless working it would be a good first step.
I have a wireless connection to the internet, as well as a wired connection to a local network. When the wired connection to my local network is enabled, the wireless connection to the internet no longer works until I disconnect the ethernet cable.
(This setup used to work just fine when I was using Windows, but now doesn't seem to work. I wasn't using IP aliasing in Windows, but I am now, which may be causing the problem.)
My original connection to the internet was a wired one, at eth0, so once I got wireless enabled (on eth1), I created an IP alias to my local network of eth0:1 which is a static IP on my local network. The only configuration I did at all was to add a file named /etc/sysconfig/network-scripts/ifcfg-eth0:1, with the following contents:
Code:
And NetworkManager just seemed to pick it up automatically - I didn't change anything else in NetworkManager or anywhere else.
(Also I use 'service NetworkManager start/stop' entirely rather than 'service network start/stop' to manage my connnections. i.e. I did 'chkconfig network off' when setting everything up initially.)
A friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.
Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:
1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.
2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).
3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.
Can Cat5e RJ45 connector crimper be used for Cat 6 connector because I heard cat 6 connector is different from cat 5e connector and also same question for cable tester can cat5e cable tester be used for cat 6 cable?
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
