Ubuntu Networking :: Router Access - No Internet After NM Icon Disappeared
Apr 28, 2011
Today I set my HPG50 with Ubuntu 10.10. I used network install disk, then tasksel to add Ubuntu Desktop. Everything was fine, I set up my samba shares and a few other things. I had the NM icon on the panel but did have to configure. I was on wired connection and I could surf no problem. When I went to set up the wireless, I noticed the icon was gone. I know it was there after the install. At some point the network manager icon disappeared, not sure when because I could still access the router and internet. I spent a few hours surfing google and the forums trying to find an answer. Then, after running update and upgrade I lost internet. Even though I could see the router, I connected straight to the modem, still no internet access. I unplugged the cable from that machine and plugged it into my other system and I could surf just fine.
It was clear that nm-applet was running from running nm-applet at the terminal - nm-applet - "An instance of nm-applet is already running - Warn Couldn't initialize the D-Bus manager. nm-tool - State - connected, Driver r8169, State Unmanaged, Default no. NetworkManager.State - All three entries are set to "true". It seems clear that some other app is managing my connection as I can access the router and am currently serving video to my apple tv from this system. How do I find which app is managing my connection?
I've installed ubuntu 9.10 64bit onto a usb flash drive and found that even though I can connect to my safecom adsl modem/router I can't get an internet connection, the previous versions work and it works with a Linksys router. Is this a known issue with a fix?
I have a dual-boot desktop with Windows 7 and Ubuntu.Problem: Linux does not recognize my D-Link DWA-131 Wireless N USB Adapter. So, I can't access my wireless router or the internet.D-Link has a Linux driver for the DWA-131 posted on their website URL...that includes a readme file with long, strange, convoluted instructions on how to install the driver.
I changed to a 4 port ethernet router (D-Link DSL-2542B Adsl2+)with intention to share Internet access with my brother (he's on Vista).Initially it all went well,but 3 days ago there were connection problems occured on the part of the ISP. Without realized the problem,I had reset the router.This morning I've been informed by the ISP that the connection has been re-established.So,I accessed the Internet via the 4 port router but failed to do so (server not found).Suspecting that the problem was from the 4 port router,I reverted to my old Adsl router (DSL-520B single port) and without any problem I managed to access the Internet back.I really need help to configure back the 4 port ethernet router to its initial state.
At work, we (like almost everyone) are still full-on windows. I am currently trying to get away from windows because I am not a fan. my current windows machine (different from my Ubuntu machine) is accessing the wireless network fine, and there are no obvious problems there. Also, my Ubuntu machine can access my wireless network at home, so I know there are no driver issues. I set up the connection for the Ubuntu machine, and it seems to be connecting OK. I can ping internal IPs and by all statuses, the connection to the router is functioning. However, when I attempt to load a web page or ping a domain or external IP, it fails. I tried to ping the IP, thinking if that worked, it's probably the DNS, but pinging both domains or IPs fails. I have looked around at forums and posts, but none of them seem to match my issue (that's probably not true, but I am struggling to see the commonality).
Here are the results of "netstat -r":

And here is "ifconfig":

I have I fileserver on my home network. It has a static IP and is plugged into the back of the wireless router. It is fine on the network but cannot access the internet. I noticed this when I was trying to update my package list. This is what is in /network/ interfaces:
I have 2 pcs at home. I dont have a switch so I can connect only one PC at a time to my adsl router/modem for internet access. In the past I had successfully connected the two PCs (NIC to NIC) to each other using the same ethernet cable which was supplied with my dlink adsl modem.
Recently the motherboard of on of my PC went bad so I replaced it with a new one. The problem is when I connect the two using the same Ethernet cable they won't connect. The lights on the Ethernet port won't light up. I can still connect both of them to the adsl router (NIC to Router) (one at a time).
When the laptop boots I get a very brief message to say "wireless network available, click on icon". But it disappears in a second. I'm not clear whether my WL-140 card is in device wlan0 or wmaster0. Here's what lshw -C network says... *-network description: Wireless interface product: ISL3886 [Prism Javelin/Prism Xbow] vendor: Intersil Corporation physical id: 2 bus info: pci@0000:06:00.0 logical name: wmaster0 version: 01 serial: 00:0c:f6:14:a4:35 width: 32 bits clock: 33MHz .....
I use openSUSE 11.1 since quite a bit and I frequently use YAST (not as root of course). However, since the problems I have to deal with while trying to install WiFi internet access I meet the following problem. I call YAST, get the small authentication screen, I give the right password, which seems to be recognized as such, but I never see YAST appearing. So I can't manage neither my hardware, nor my software.
While my wifi still is working just fine (I'm here aren't I), the Network Manager has disappeared from the Notification Area on my panel upon reboot.Have all current patches, so have no clue what to do. Most likely is a bug.
Ive had a few freeze ups on this system but the last time it affected the top panel.The wireless icon has disappeared to be replaced by an extra bluetooth icon.screenshot attached.Is there any kind of clean up utility (like tune up utilities in win)Also, any kind of log so I can trace this freeze up Iḿ getting.Ive only just got this laptop so dont know if it did it before although prev owner never mentioned it.
OpenSUSE 11.3 x64 KDE I dont know what happened it is a new install thats been running for 2 weeks . Now for some reason I can not access the internet or the router. Samba is working with Dolphin I can browse shares on local network both Windblows and Linux and ping local IP's. But I can NOT ping my router (the default gateway IP) with this box or access it with firefox so no internet. A VirtualBox of XP Pro running on this box has no problems with its bridged adapter getting out and seeing the router. I disabled the firewall, added gateway IP to network settings, disabled ipv 6 from the get go, added service provider dns's to nameservers tried opendns servers also.
I just finished setting up my small server, however I realized that no one can connect to it from the outside. The reason being is that my router is assigning internal ip's and dyndns is linked to that. I need port 80 for the Apache server, but if I have the router forward that port to my particular ip, won't it screw with everyone else's internet too?
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 use slackware 13.1 i have apache, mysq, php - working i have a router netgear WPN824v2 - latest firmware port forwarding to my comp 192.168.1.105 port 22 i can access my ssh from my internel lan, but i cannot access it from the outside... i used [URL] to test the port and it says that is closed. i used PFportCheck Program on my other windows computer and it says that "port 22 is opened on another device!" - which is good because it's opened on this computer. also tried to changed the port on sshd_config to 6655 and 22 but it's still cannot connect...
just installed Ubuntu Netbook remix on my acer aspire one, and come across a problem Ive never faced before. Im able to Connect to my router (and access it through the internal ip address) but as soon as i try access anything outside of my network there is nothing!
This i found odd as first i thought it might have just been my Routers problem, but seeing as all my other computers were connected to it with no problems (wired and wireless) I quickly traced the problem back to the laptop.
After this i decided to see if after a simple update would fix the problem. so i connected it up through the Ethernet port once again it connects to the router but no internet! I have tried everything in my knowledge, but with no success!
I am trying to set up a basic router. I am running ubuntu server 10.04(just installed it today!) I have a verizon aircard(mobile broadband card) that is connected via usb. I am using wvdial to "dial-up" the connection. This works just fine and gives me a device on ppp0. There is a single lan connection on eth0 set up as a static ip address under /etc/network/interfaces. I don't even have any firewall running yet. For whatever reason, I can only get out on the internet when eth0 is set to get its ip address through dhcp. When I set it up with a static ip, I get for example:
If, however, after I have booted and the wvdial has been started, I set up eth0 as dhcp, run /etc/init.d/networking restart, set it back as static, run /etc/init.d/networking restart again, all work well. When I reboot the system with the static ip on eth0, and connect to wvdial, I get no internet again.
My internet works fine if I plug directly into the modem, but if I go through the router either using ethernet or wireless it doesn't work. I can access the router perfectly when using wireless and change settings and all that but cant access the internet. From what I've read it isn't a DNS issue because I cant get a result from pinging an ip, so I think it may be something firewall related but I'm unsure.
I am connected to my wireless network but can't connect to the internet. I have searched the ubuntu forums for solutions but none seem to work for me. I can post terminal outputs if required (I know that much).
My router is a Netgear router with Comcast, and after going on Ubuntu for a couple hours just doing normal things, the Internet disconnects. Then I have to restart my computer and start everything over again. I check the router and everything seems to be fine, I even unplug everything on the router first (like I am instructed to do so if this sort of thing happens) to make sure that's not what is causing the problem. It has to be the Ubuntu system.
I am dual booting XP and Ubuntu 10.10 64bit on a Dell Latitude E6410 and I have a Linksys WRT120N router connected to my Modem.
So the weird thing is, under XP I can use the internet while connected to my router. Under Ubuntu I can't use the internet while connected to my router. But I can use the internet in Ubuntu if I connect to my neighbor's router called "linksys". So something happens when I connect to my router that makes Ubuntu not able to access the internet. But if I'm connected to my Neighbors router or if I use XP while connected to my router I can use the internet.
I have been using Ubuntu for about a year, so I'm getting better but still a noob. I've tried to figure out what's going on by looking at other forums and posts and trying to see if anyone has solved this. So far I've had no luck. This is also the first of many problem I have encountered that I have been unable to solve using online posts, and is the first problem that I have had to resorted to creating a post to try and fix.
I'm running a Natty machine wired to a TP-Link router (TL-WR841N) with additional Ubuntu and Windows machine on WiFi. Recently I've had some problems with connectivity on the Natty machine. Connectivity is fine as far as the router, but not beyond it. This applies to all browsers, Software Center, Aptitude and anything else you can think of. Now, normally at this point I would call my ISP, but the thing is, all other machines have connectivity. I've checked the cables twice and anyway, if it were them, I wouldn't be able to ping the router. Router has ping functionality to outside and it's working, have tried ubuntu.com and google.com. Also, connectivity between the wired and wireless machines is fine, pings are flying across the network beautifully.
I have a wireless network in my house through a Zyxel P-320W router, and I've noticing that the signal strength isn't very good in the basement. Now I have this old D-Link-624+ router lying around for a long time and I've been hoping to get it to work as an access point, that way I can move freely around the house without changing which router I'm connected to.
I have two laptops with me here at school, one bigger one [home computer], and one smaller one [netbook]. I take the smaller one with me to class and when I'm out and about, however, I keep all of my things on the bigger one. I would really like to be able to set up some sort of SSH port forwarding for the bigger machine so that, when I'm out and I realize I left file X on my home machine, or I want to listen to a certain song, or whatever, I can just scp it to the netbook. The issue is, at my dorm, I'm stuck behind a firewall and can't just set up a SSH daemon and port forward through the router, I need a more clever solution. I do have a home server (not with me at school), which I commonly use for transferring files. Basically, I'm wondering if there is some way I can SSH into my server box, with reverse port forwarding so that, when I am out and about, I can just log into my server and copy files from my home computer for use on my netbook. I've tried a couple of solutions which come up from google "reverse ssh" but haven't been able to get them to work. A step by step guide to doing this would be great. Again, the setup is:
Home server [ssh-able] Home Computer [behind firewall, can't ssh into at the moment] Netbook 
Want to be able to SSH from Netbook to Home computer, probably using Home server.
After a recent upgrade I have lost the top right icon in the top panel - so I cannot Set Status, Lock Screen, Guest Session, Switch User ..... Restart, Shutdown. I have right clicked on the top panel and installed the Shutdown icon so I can shutdown but I have lost all the other functions including the 60secs countdown. Is there any way I can get the standard top right icon in the top panel?
my username superimposes the turn off button on the menu bar. Now on the top-right corner of the screen, I have my username displayed twice, consecutively. I am unable to turn off or logout as the icon itself is missing.
