Fedora Networking :: Lost Internet Connectivity After Installing New NM Packages

May 2, 2011The internet has been working happily on my Mythbuntu machine for many months but stopped working overnight.If I try to do "sudo start networking" I get a "Job failed to start" message.There's also a solid orange light on the ethernet socket.As it's been working for months, I don't think my interfaces config needs updating.Looking at what's been updated recently on the system:
1) I've configured the machine to wake from USB. It was working for a couple of days so I don't believe this is the issue.
2) I set up wake-on-lan with ethtool. Again, this was working (although it did seem to disable wake-on-usb and required a reboot to fix)
3) Update to 11.04 - I said no to this, as 10.10 was working very nicely indeed.
I've disabled wake on lan and rebooted. No joy.
ethtool detects the ethernet controller ok and it's listed in lshw.

Jan 23, 2011I had my desktop running ubuntu 10.10 at my sisters house hooked up to a router sharing internet with her boyfriend never had a problem with it there. I moved into my own apartment this week plugged the cable modem directly into the broadcom ethernet card and couldn't get an ip or anything it wouldn't connect period so I ended up hooking it up usb which works but only at speeds of 5-7mbit when I have 15mbit connection. So I put another ethernet card in hoping it was just problem with the card and tried it that worked.
I got a connection but it was incredibly slow like getting maybe 5k a second so I open network tools in administration menu and start pinging google. While I'm waiting on a bandwidth test to complete and it takes off getting like 20mbit keeps that connection for a while then out of nowhere just drops to almost nothing. Again for a few minutes then falls off completely so I restart and it does the exact same thing starts off slow then something clicks and it works great for 5 min then nothing?
Ubuntu Networking :: Dual Ethernet Networking - Lose Internet Connectivity?
Apr 18, 2011I have a server with two ethernet ports. I configured eth0 to be static, set at 10.1.10.148. I plugged in another router into the other ethernet port in order to configure that router. I configured eth1 to use dhcp. Using /etc/network/interfaces rather than gnome network manager. When I did this, I lost internet connectivity (internet routes through eth0 of course)
- Why did I lose internet connectivity?
In order to recover internet activity, I had to disconnect the new router on eth1 of course, and do sudo ifdown eth1. That wasn't enough however. After rebooting numerous times and pulling out my hair, I finally tried configuring eth0 as dhcp, rather than static, and this fixed the problem.
- Why didn't sudo ifdown eth1 solve the problem? What information was saved between reboots that somehow remembered that I plugged in the new router? Because my thinking was if /etc/network/interfaces was identical, and the network topology was identical, after a reboot everything should be restored, but it wasn't.
Ubuntu Networking :: Get Internet Connectivity To Phone Through Wifi?
Apr 21, 2010I have an iphone, I am trying to get internet connectivity to that phone through wifi. I dont have a wifi router. But i do have a laptop with wifi card. I am connecting to internet via cable modem. In win7 I used to create an accesspoint and do the ics from ethernet card to share via wifi card. It used to work perfectly.
Now as I am sing ubuntu, i want to do the same. I have intalled firestarter, and shared the internet connection through wifi card(wlan0).After this I created an accesspoint using the gnome network applet. Now i can connect my ifone to ths accesspoint. But there is no internet connectivity in my fone.
Ubuntu Networking :: AR5001 Chipset - Wireless Networking Randomly Loses Connectivity And Can Not Regain Connectivity
Jun 25, 2011Wife's laptop has AR5001 Wireless Adapter laptop model is Toshiba Satellite A215
Problem : Wireless networking randomly loses connectivity and can not regain connectivity, the only apparent solution is a full power down , this is not even certain to work. The card works under Windows, she hates Windows. (I love her for this) I know it's not faulty hardware , because it will work for days on end under Windows without problems.
Things I've tried : madwifi drivers (any and all versions available) : These increase stability of the signal and seem to delay the inevitable however it still happens. When using these drivers the only option is to unload them modprobe -r then reboot then remove them again and re add them. It makes no sense why this works, and if I don't remove them prior to rebooting it will not work.
ATH5K drivers : These are pretty much junk, results are unpredictable at best, sometimes it will work perfectly for a few hours, sometimes it will not work at all. Nothing is repeatable, I can't seem to force whatever condition is causing this. rfkill does not show the wifi being blocked (hard or soft), unblocking it anyway does nothing, only way to make this work and it's iffy is to fully power down wait 5-10 minutes turn it back on and it MAY decide to work.
Firmware update : Updated the Toshiba BIOS to the latest version of the firmware 2.0 no joy here either. Same issue both sets of drivers.
Tried different distros and kernels : I've tried Mint 9, 10 ,11 ; Ubuntu 10.10, 10.04 , 9.10 and 11.04 (which is currently installed) , Fedora and OpenSUSE. All are giving the same problems. I have also tried a slew of different kernels no joy from any of them (I'm not at the computer with the issue now I will post exactly what kernel versions I've used when I have access to the machine).
Another useful bit of information, the hard switch to disable/enable wifi WILL disable it but turning it back on does absolutely nothing. The hotkey does nothing at all. The bios does not have an option to disable or enable the wireless card.
I will also post the typical lsmod , lspci , iwconfig all that good stuff when I get back to the computer in question. I'm probably just going to buy a PC card for it and give up on that one, but this is driving me insane and I would really like to see it resolved even if I do replace the hardware.
Ubuntu Networking :: No Internet Connectivity - Cannot Access Pages In Apache
Nov 9, 2010I can connect to anything locally, I can SSH in locally but nothing works from outside my network (can't access pages in apache, can SSH, etc.) I've checked the logs I can think of, but what should I be looking for? The last thing I did today was add a FW rule to log and drop from an IP, saved my iptables to a file in /etc. (this was at 10:45am). The last time I successfully logged in remotely 1:03pm. I connected multiple times in between. I've rebooted remotely once or twice. That's it. I've already flushed iptables.

Apr 23, 2009I've just installed Fedora 10 to basically work as a NAS for another machine - but also serve a couple of web pages. After having alot of issues with network manager (with it changing the subnet so nothing would work), I'm now almost there:
I have two network cards connected in the server:
1) eth0 connects to a switch that ultimately connects it to the net (on a 10.0.0.* network)
2) eth1 connects directly into another server for backups (192.168.0.* network).
Now when I setup eth0, I get network access can ping/ update/ surf the net - absolutely no problems, but when I connect eth1 in - the net dies and nothing works, I can ping devices on both the 10.0.* and 192.168.* networks, just nothing past the gateway. I presume this is either a route or DNS issue, but am unsure about where its falling foul - both the resolv.conf file looks fine as do the ifcfg-ethx scripts.
Ubuntu Networking :: Assigned IPV4 Settings Manually - No Internet Connectivity
Jun 20, 2011I am new to UBUNTU. I installed the latest one alongside windows 7. I am having problem with the internet connectivity. I configured the static ip settings right I guess. Edited the Auto eth1 and assigned ipv4 settings manually and entered everything correctly.
Address 192.168.xx.xx
Netmask 255.255.255.0
Gateway 192.168.xx.xxx
DNS Server xxx.xxx.xx.x, xxx.xxx.xx.x
Do I have to put MAC Address as well? Which is addressed as 'Network address' in Windows where I put this MAC. I have on board Realtek RTL8101E Family PCI-E Fast Ethernet NIC (NDIS 6.20) Network adapter. Do I have to install the driver?
Fedora Networking :: No Internet Connectivity - Status Inactive PAN0
Mar 3, 2009I'm new to Fedora 10 and still a newbie with Linux in general. I installed F10 on an old PC I had....and the install went well..however, I'm having Internet Connectivity issues.
Here is what I did so far:
Did an ifconfig command and I have the following:
pan0 Link encap: Ethernet HWaddr D2:30:36:AF:61:95

RX bytes: 0 (0.0 b) Tx bytes: 8676 (8.4 KiB)
When I go to the Network Configuration Panel I see the following:
Status: Device: Nickname: Type:
Inactive pan0 pan0 Ethernet
Tried to activate and it states Activating network device pan0, please wait... determining IP information for pan0.... A few minutes pass by then. It indicates it failed. Cannot activate network device pan0! I have disabled the Controlled by NetworkManger and enabled the Activate device when computer starts.
Fedora Networking :: Flaky Internet Connectivity - Network Inactive In NM Panel
May 28, 2011I just installed F15 on a laptop that previous had F12 working well. During install, it finds my wireless card and seems to set it up fine. The full install ran with the wireless active without any problem that I could see. Now, when I start up, I see Network Manager tells me that the wlan is active, but it doesn't show my specific network. If I click on the NM tray icon and open up the panel, my network is shown but it is not "active".
I can double click on it and it will become active - shows the little globe next to the antenna. This works fine for about 2 web pages worth and then FireFox 4 stops being able to find web pages. If I go back to the panel, double click on my wireless network (which looks like it is active already), and reactivate it, I can get the page I was looking for in FireFox, but within a couple of minutes it will stop.
Likewise with yum, while I'm installing software, I'll occasionally get errors like this:
[URL]: [Errno 14] curl#6 - "Couldn't resolve host"
If I reactivate my wireless network in the NM panel, it continues fine. Other computers/phones connected to this network seem to work fine. Is NM known to be problematic in F15?
Ubuntu :: Virtualbox PUEL Lost USB Connectivity After Upgrade To Karmic?

More confusing is that there are no "alsa" looking processes in ps -A. But apparently, the basics are there

There's only one thing in init.d that seems relevent to alsa:

Ubuntu Networking :: Lost Internet Connection - Now Can't Get It Back
Jan 23, 2010I am running ubuntu 9.1 on a Dell Dimension 2400. After installing ubuntu on the pc, it was automatically recognizing my router and connecting to the internet fine via ethernet. Then, my roommate unplugged the router and it won't recognize it. I can't access my router settings, and ubuntu is recognizing it as "inactive" but every other computer in the apartment runs fine. My PC uses a broadcom ethernet controller, and my router is a Linksys wireless N.

Ubuntu Networking :: Lost Internet Connection When Upgraded 8.04 To 10.04?
Jul 25, 2011I was running 8.04 and my internet (Comcast) comes via a Motorola SB5100 cable modem then into a Netgear router then into my Dell. When I upgraded to 10.04 yesterday, I lost the wired connection. The wireless connection still works fine, but I have not been able to get a wired connection. Also, most online solutions reference the Network Manager, which is nowhere to be found.
Anyone have any solutions? I would be willing to revert to 8.04 if needed, as that worked fine, and obviously I quite regret the upgrade!
Ubuntu Networking :: Internet Access Allowed When VPN Connection Lost?
Mar 16, 2010As I view it, Ubuntu has a great security risk in that it still allows internet access when the VPN connection has been lost, for whatever reason. As it is now, when the VPN connection fails you get bumped back to using your regular IP, and whatever you are doing becomes transparent to anyone watching. This is simply unacceptable for an allegedly secure platform. Does anyone know of a way to fix this with a script/program, or is there a distribution/OS that allows this? Windows re-dials the vpn automatically, but still allows internet access in the mean time.

Ubuntu Networking :: Internet Connection Lost After 10 Minutes Surfing
Apr 23, 2011I do have a problem with my internet connection at home, I've a Huawei router and ubuntu 10. When I connect to the internet whether wireless or wired I become able to surf the internet for less than 10 min then it cuts off! and to be able to surf it again I need to restart the whole system!
I used this command to restart the networking but in vain
Code:
sudo /etc/init.d/networking restart
On windows I do not face this problem with the same internet connection. I do not face it either when I'm using my campus wireless connections using ubuntu/windows!, so the problem is related to my home connection+ my OS.

View 3 Replies View RelatedNetworking :: Detecting And Logging Lost Internet Connection?
Dec 8, 2010We have an Asterisk machine that we suspect periodically loses internet connectivity, causing all calls to drop. First, would this sort of thing be logged anywhere out of the box? I haven't noticed anything in /var/log, but that doesn't mean it's not there. If this is not typically logged, how I might go about logging it? I'm currently running a bash script from cron every 5 or 10 minutes which pings Google and writes success or failure messages to a log file. This works fine for extended outages, but if the internet connection drops and comes back between cron runs, it won't be caught.
View 4 Replies View RelatedNetworking :: Automatic Internet Configuration Lost After Update?
Sep 10, 2010After running a large update and rebooting a few weeks ago, I found that my internet connection had stopped working. My internal network still worked fine though, so it I know it's not the card itself or its configuration. After a bit of trial and error I discovered that simply running dhclient brings the connection up again, so it appears that something is interfering with the initial dhcp update to my ISP (or something like that; I'm no expert in this area. ) My usual policy in cases like this is to wait through two or three updates in the hopes that it's just a temporary problem, but it's been a while now and subsequent updates haven't fixed it.
I've tried looking around, but I can't come up with search criteria specific enough to narrow it down to my specific situation. I'm not even sure where to begin looking to diagnose the problem, nor do I know which package update(s) could've affected it. I'm not sure what might be useful, but here's the relevant entry in /etc/network/interfaces. I have it configured with a static internal address, with my router as the gateway.
Code:
# The primary network interface

But only Fedora can't connect anymore, the Windows PC has connection as well as my Mac OS X (I dualboot Linux on my MacBook). The Ethernet connection works as well, when I unplug the cable, Fedora gives me a message, but I just don't get into the internet!
Does anyone have an ides what I have to do? I don't know anything about network connections and I'm new to Linux...
I already restarted the Computer, but that didn't work, and Google didn't really held either.
Ubuntu Installation :: 10.04 New Install No Internet Connectivity / Need That
Oct 5, 2010I just installed Ubuntu 10.04 as a dual boot with Win/XP, using the text based installer. Installation seems to have completed OK and Ubuntu boots as expected - but Firefox cannot find any web-page.
How do I start look for the problem cause?
I should say that I previously had installed Kubuntu 10.04 (64 -bit). It was installed for a few months up to May 2010, but then it suddenly lost all internet connectivity after I hibernated the system. Win/XP continued to work with no error. Despite some months of help and advice from the Kubuntu forum, I was unsable to solve the problem. Indeed one piece of advice resulted in the overwriting of my Win/XP installation. I have now re-installed Win/Xp and decided to install 32-Bit Ubuntu - but I am back into the 'no internet connection' problem again. Win/XP works fine.
