Ubuntu Networking :: 9.10 - Wireless Network Manager Cannot Find My Router
Feb 8, 2010
To start off I have a Rosewill rnx-n2x wireless adapter and a Dlink 4500 router. The problem is, the wireless network manager detects every wireless router in the neighborhood, except mine. I see this persons, and this persons, but no "My router Not yours". I even tried doing the hidden network setup and still nothing.
I have read that the rnx n2x isnt supported by linux, although I've seen solutions to make it work (which didn't work, mkdir command kept getting denied during make) link to what I'm talking about: [URL]. What I don't get though, is that if the rnx n2x isnt supported by linux, wouldn't I not be getting my neighbors connections to begin with?

All settings are correct as far as i can tell. The wep key works on all my windows boxes. When i have connect automatically enabled it never tries to connect. if I go to edit it it pops kde wallet up i put in credentials. wallet goes away then nothing happens. if i double click connection to my router also nothing happens. I have the wep key in there and i even made it visible to make sure.

I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

I installed lxde on Ubuntu 11.04 but I cannot find any network manager to connect wireless LAN. There are some sort of network manager and they show available signals to connect but cannot find any way to command computer to "connect" it.

I'm trying to get online on my laptop, I just installed Ubuntu 10.04 (Side by side with Windows 7.) I'm looking over the networking help files, as well as the troubleshooting and nothing seems to be working. [URL]. From this troubleshooting guide it tells me to open the terminal and type the command "sudo lshw -C network" and when I do, it asks me for my password but when I try to type it, nothing comes up. So I run it without typing sudo. It says "*-network DISABLED" which in the troubleshooting guide means that my router is off, but I'm clearly online on this computer as of right now.

Right so yesterday my internet worked fine. Today - no connection at all. The light for my cable on the router doesn't even show up. I originally had indicator-network installed, so when the internet first stopped working, I tried a few other options such as tethering to my phone via usb and bluetooth (which I have successfully used in the past). However, these didn't work, and I figured that as connman is still in beta, maybe that was why. So I reinstalled network-manager and network-manager-gnome via a usb stick, uninstalled indicator-network, and rebooted the computer. Still no internet.
When I click on the applet, it says "No network devices are available". This is odd, as I definitely have a network device... it is part of the motherboard. So I thought I'd do the SMARTlan test or whatever it's called. It's part of my BIOS, so I ran that and it returned results that I (kinda) expected: when the cable wasn't plugged in, it returned one set of results. When it was only plugged into my computer (and not the router), it returned another set of results. And when it was plugged into both my computer and the router, it returned a third set of results. So that leads me to believe the cable itself is fine.
And when I move the cable to a different port on the router, nothing changes. The corresponding light still doesn't come on. Network-manager, telling there are no network devices. The BIOS can see the ethernet port and the cable. And the router is functioning perfectly for my parents' computer and my ps3. And I have checked the cable to my computer for physical damage - it follows the same path as the one to my ps3, and on top of that, nothing physical can possibly have happened to it in the last day. This happened once before, except I don't think the network devices were lost.

just switched from Windows Vista to Ubuntu 10.10 on my Toshiba laptop and I'm loving it, except for some wireless connection problems. About 70% of the time, my computer is unable to find any wireless signals whatsoever, despite being right next to the router. When it does find the signal it connects fine and runs great, but most of the time it doesn't show any signals at all. I can't find any pattern to when it does or doesn't find the signal. My result for the "sudo lshw -C network"

I am a Windows refugee who discovered Ubuntu as a way to save my files from my virus-ravaged computer. Had no installation discs for Windows, so when I had to wipe my hard drive and start over, I decided to give Ubuntu a try. I've had mixed success, but that's another post...
Right now, the problem is that I installed 10.10 two weeks ago and was able to connect to the Internet with no problems - until yesterday. Suddenly, our wireless network (the only one in the vicinity) does not come up as available in Network Manager. In fact, the entire wireless option disappeared. I know there are many posts and threads on here about this, but weeding through them trying to find an answer is more frustrating than actually dealing with the problem. I know the router works because I can post on this forum from the Macbook. I really like Ubuntu and would like to keep using it, but not being able to connect to the Internet now on top of the other issues I've had is making me doubt I want to continue down this Linux road.
P.S. When I attempted an analysis through System Testing, it said something about there being no proprietary drivers?

I have an existing network that connects to the 'net via a Linux-based firewall. That system has two ethernet interfaces: one to the DSL modem and the other to the internal switch. Future plans were for adding a second "internal" interface with the idea of moving servers into that (think DMZ). But while I was planning for that, the missus has decided she wants to pick up a Windows laptop and would like to be able to use it wirelessly at home. I have access to a (free!) Netgear WGR614L and was hoping it would work. Unfortunately, I'm unsure how to add the wireless capability to our network.
Questions:
Is it best -- or even possible -- to use one the wireless router for this?
Is it possible to merely hang the Netgear router off the internal switch and set it up for the wireless users? Or...
Would I need to add another ethernet interface to the firewall and hang the router off that? The address of this new interface would act as the default route for the wireless users. Then I'd need to (I assume) add more rules to the iptables configuration to deal with the new network. (I sort of like this option -- it it's actually feasible -- as I can easily shut down any wireless access by logging into the firewall and stopping the interface connecting the wireless router.)
I've taken a look at the setup guide on the CD that came with the router and it assumes that you have a modem connecting your PC to the internet. The instructions have you placing the wireless router between the modem and that PC. For our network, that would have the wireless access coming into the "dirty" side of the firewall. (Not what I would like.)

I have a client that has a basic network that uses comcast cable. He bought a NETGEAR N300 wireless router which has a 192,.168.3.X network and he attempted to add it to his 10.10.10.X network and all is fine. He laptops and such can get to the internet fine. The issue is he cannot get to any of his devices on his 10.X network. I have looked at his comcast router which is controlling his 10.X network to see if I can add addition routing to his 192.X network. but didnt see anything. I also am not to familiar with the N300 wireless router. I was going to have the wireless DHCP turned off and some get it to pull the DHCP stuff from the comcast side but dont see any area to do this.

I've been having a network problem that I've been able to temporarily solve by rebooting the router, but even that can be shaky at times, and it can sometimes disturb others' internet activites, so I'd really like to tackle this while I can. I had an old thread about this, but it's ancient history by now, and plus which, I've got a bit more Linux experience and patience than I did before.
The basic problem is that NetworkManager will associate and connect to my home wireless network, but a) it won't let me ping the router or anywhere else ("Destination Host Unreachable"), and b) the connection lasts for maybe a couple minutes at most. If I reset the router, however, 9 times out of 10 it will associate and connect successfully and I can get online, but I have to run a constant ping to the router with a 10-second interval, otherwise it drops the connection, unless I'm doing a lot of other heavy network activity.
ping 192.168.1.1 (the router):
Code:
I've tried wpa_supplicant, but this is what I get (it's apparently unsuccessful...? ESSID/MAC addresses censored where necessary):
Code:
The last prompt line is included because I cancelled it myself; it didn't abort on its own. If left unmonitored, it basically keeps doing this over and over, with no visible network activity at all.
With NetworkManager, I can keep selecting the network's ESSID over and over, and it seems to reconnect, but I still can't ping out anywhere. I'm using a Netgear WN111v1 wireless adapter with ndiswrapper and the Windows drivers. I have no idea what the chipset is, and I doubt that Linux drivers exist for it, even if I knew what it was. The router is using WPA2 security (hence my trying wpa_supplicant)
lsusb:
Code:
ifconfig wlan0 (while connected; IP/MAC addresses censored where needed):
Code:
ifconfig wlan0 (while not connected; IP/MAC addresses censored where needed):
Code:
Code:
I only include this for format checking purposes. The commented out "psk" is the actual text passphrase, while the uncommented one is (presumably) a hex representation of the same key. Is this correct? I've never done this with wpa_supplicant before, I've only used NetworkManager (which is a pain in the @$$ because it requires X to run, and so it disconnects any time I log out/back in ).
Is there any hope of getting my wireless connection permanently working, so that I don't have to reset the router every time I need to reboot or log out/back in?

My computer takes a while to connect to my Linksys N router.
It used to connect in a snap of your finger automatically.
Now it does not.
Yes I have tried manual configuration, and double checking the password, ssid, protocols, and security type.
WPA2 personal is the security type.
There are maybe 4 different ways I know how to connect. The most annoying thing is when this box pops up saying to type in a password for the network connection.. and keeps popping up even when everything is right.
All I need is a reliable, easy, and automatic program to connect me to the internet, maybe even before I log into my system.
Linux Ubuntu 8.04 LTS Desktop Edition is my system. Brilliant system.

My son lost his USB Wireless stick for his Computer. I had thought I heard that if you had a second wireless router, you could use it somehow to detect the wireless router you have already set up in your home (like using a wireless card)? Is this what Ad-Hoc is? Either way, can this be done and if so how? I use a WRT54Gx2 Lynksys router and have a TRENDNET TEW-432BRP wireless router and also a spare D-link DI-514. I use ubuntu 10.04, and also wanted to know if I connected one of the router to his on the LAn port could he connect msaybe through an Ad-Hoc on my local computer here? He uses XP on his. I'm a newbie to linux and networking in general.

I moved my server and network equipment, and now the wireless works but I cannot get my server online. I host a website, so this is kind of urgent.
I have a wireless router and can access the internet fine on my laptop. My server is wired & connected to the router. It sets up the networking properly.. ifconfig has an ip address, the default gateway is present. But I cannot ping google, or even the router. It says destination host unreachable.
So I go back to the laptop to check the router settings.. sometimes it likes to assign the server the wrong internal ip. But, I can't access the router settings either! The page (192.168.1.1) times out. Same with trying to ping the router. How can the laptop be online if it can't reach the router?
Oddly, ifconfig on my laptop reports an ip address starting with 99.233. It's always given me an internal address starting with 192.168. What's going on here? Is the router not allocating an internal ip? I use wicd to connect, if it's relevant.
We have a windows laptop that can only get a "local connection". Now it does sound like the router is forwarding directly to my laptop, instead of allocating internal ips.

I have 10.04 installed on my HP MiniNote Netbook. If I plug it into the the ethernet directly, all is well, but if I only use the wireless, i get no DNS servers. And one of my wireless networks is on the same router as the wired connection. Also, wireless works just perfectly on my MacBook Air. So, I do not think it is the router. So why am I not getting DNS addresses? How would I set them manually? I can't figure out how to start network manager.

I want to set up a static IP on my laptop that connects via wireless to my home network. I have 11.04 installed on my laptop. When I try to use the manual IPv4 setting in the network manager the save option gets greyed out. I tried to edit the /etc/network/interfaces file but all the examples I could find on the net refer to eth0. I tried replacing this with wlan0 but this did not work. I tried installing wicd but I kept getting "Bad Password" errors even though I know the password is correct. A number of people recommended uninstalling network manager to get wicd to work but many other posts said that uninstalling network manager didn't help so I didn't want to go ahead and uninstall unnecessarily. Besides I figure if Ubuntu is distributed with network manager there must be a reason for having it. So what do I do to get a static IP address for the client on a wireless connection?
1. I went to network manager and selected "Connection Information" On the information window I saw the following:
IPv4
IP Address: 192.168.1.6 (This is the item I wanted to change and make static)
Broadcast Address: 192.168.1.255
Subnet Mask: 255.255.255.0
[code].....
2. I went to network manager and selected "Edit Connections"
3. I selected the wireless tab and then the wireless network I wanted to edit
4. I clicked on the edit button and then I clicked on the IPv4 settings tab.
5. I changed method from Automatic (DHCP) to Manual

I'm not sure if I have two seperate issues or one inter-related issue. The Network Manager applet wasn't appearing in the tray, found out it wasn't installed. Installed, still didn't appear. Tried installing WiCd, WiCd did appear but couldn't find any networks. I had installed restricted drivers previous, decided it was worth another look. Found that Broadcom STA Wireless Driver wasn't installed. Tried to install, it said it couldn't and said I should review the var/log/jockey which is....excessively long.

A couple of weeks ago my laptop's wifi started acting up, to the point that it didn't function. When I click the nwManager icon to being up a list of available networks, it is empty. If I try to create a new network, with the credentials of my modem, it appears to work, and asks for the password. After I enter the password, it seems to work for about 30 seconds (much longer than normal) but then it prompts me again for the password. This cycle continues indefinitely.
I'm running Karmic on a Dell i1525. how to find out what wireless card I have.

I am trying to configure a Travelmate 2490 to connect to my wirelessr router, a TP-Link TL-WR941ND. It does not show up in the list when I use network manager. However when I look to see if there is a driver for my wireless network in the computer it seems to find one. I am quite a beginner so some basic troubleshooting would be great.

I was using ubuntu 9.04 and everything was working flawlessly with my network. The only problem with 9.04 is that it was unsupported and I couldn't install the packages I wanted to such as Cairo dock so I decided to upgrade to 9.10 which is a lot better. However I ran into a problem that I never had on 9.04. I cant connect to MY wireless network (my Belkin wireless card can detect networks but not mine) I have a netgear router WNDR3700v2 with WPA2 encryption. I thought that the encryption was the problem so I turned it off and ubuntu could still not find the SSID through the network manager. My SSID broadcast is on.

I deleted all APs in my Wireless Section of network manager. After that, the whole network manager icon disappeared. I added the icon back on the panel, but I don't think its the right one. It doesn't do the two green cicles thing when I connect my ethernet wire in. It also doesn't show any wireless AP when I left click on the icon. It doesn't even have an X mark on the bottom left of the icon when no network is detected

I recently upgraded from Ubuntu 9.10 to 10.04 (both 64-bit) and my USB WiFi adapter which previously worked fine stopped working. The adapter is a Hama USB stick based on the Ralink rt73 chipset. I've tried using the Ralink drivers that come with 10.04 (both rt2800usb and rt73usb) but neither work. When I use rt2800usb, the adapter is recognized as interface wlan0, however I can't see any wireless networks. When I use rt73usb (and blacklist rt2800usb to avoid conflicts) I no longer have a wlan0 interface and there is no wireless adapter shown in the network manager. I've pasted in the results of lsmod, lsusb, and ifconfig -a (with MAC addresses removed) below.

So, after doing a 'yum update', I minimized the terminal and completely forgot about it - so I accidentally went ahead and suspended my laptop before it had finished. I resumed my laptop and noticed that yum hadn't finished 'cleaning up' the packages. Nevertheless, yum continued and the process finished. After an hour or so use of the internet (wirelessly), all of a sudden the wireless network disconnected, and NetworkManager crashed. I rebooted my computer only to find that NetworkManager now says that my 'firmware is missing' for my wireless card.
