Fedora Networking :: Flaky Internet Connectivity - Network Inactive In NM Panel
May 28, 2011
I 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?

I'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
inet6 addr: fe80::d030:36ff:feaf:6195/64 Scope: Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:30 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
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.

Since a couple days ago, the top and bottom gnome panels take a long time (~25 secs) to appear. At the same time, Firefox now starts up in offline mode, and has to be put in online mode to work. Based on some threads, I tried setting [URL]..
Code:
[ifupdown]
managed=false
to
Code:
[ifupdown]
managed=true
But the problem persists. I also thought it might be related to a gconf setting so I created a new test user but the test user also has a long time to wait for the panels.

I'm running openSUSE 11.4 x86_64. When I am using GIMP, it will regularly stop allowing me to use my mouse or Wacom Intuos 3, forcing me to use my keyboard, but only within dialogs such as for scaling a layer, saving a file, etc. It's so flaky that the mouse/tablet will work sometimes and not sometimes, back and forth, within one "session" of using GIMP. It's driving me nuts. Sometimes I struggle with the keyboard (a struggle because it's indirect and sometimes counter-intuitive), other times I'll close the dialog and re-open it to see if that time the mouse (or tablet) will work. From what I've seen, I'll either be able to use both or not able to use both, rather than only having the mouse but not the tablet or vice versa.

I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.

I'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.

On one of my F10 boxes yesterday, I installed several NM packages with yum update after being advised of their availability. Today, (the first reboot since installation) I no longer have network access on that box.

I'm on opensuse 11.4 (11.3 won't work with my monitor).
My computer gets internet through wireless and I want to share that internet through its ethernet port. So far I've tried using Knetworkmanager to create a network bridge between my wireless and wired connections. I created a new wired connection and shared it using the ip address settings. I was able to get both connections active, but the device hooked up via ethernet had no internet connectivity.
I also tried this command:
echo 1 > /proc/sys/net/ipv4/ip_forward
but another test resulted in the same fashion (no internet on wired). I believe anything I add to /proc should have an immediate effect, correct?

I'm using 11.2 with KDE.
I can connect to the Internet on my WLAN just fine (using Opera) and can dload torrent files (using the same).
However, I have had trouble accessing some community repositories in the past, cannot synchronise with an NTP server (annoying since my battery is low and time and date are reset most reboots) and cannot use the lyrics function or Wikipedia function in Amarok. Nor can I connect to the net using Firefox (though conqueror works just fine...) I cannot download torrents on KTorrent either.
It seems that there is some sort of 'permission'/connectivity issue.

I 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?

I 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.

Wife'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.

I 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.

I 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.

I 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?

I'm having strange difficulties in setting a static ip for my CentOS 5.4 installation. If I use DHCP everything is fine, but with a static ip I have no network connectivity. I have done this many times with RedHat/Fedora/Ubuntu etc. with no problems and now I have no idea what I'm missing or doing wrong. I have tried to set ip as 192.168.1.20 (anything below .100 will do). GW is 192.168.1.1 and NM is 255.255.255.0. This is all I have had to use with other distros, but now when I set these I cannot even access my routers admin page or ping it (192.168.1.1). (I just did this with Vista on my other machine and all worked fine).

Basically, I wanted to use the Bootp (PXE) protocol to boot a machine (my laptop) from my network instead of using USB/DVD boot medias to reinstall if need be. My router being a piece of crap, I couldn't setup the DHCP server to allow PXE packets. Confirmed from the manufacturer that it is not possible. Well for a $140 router, you would expect the opposite. Anyways, here I am with a small machine setup with Slack, no desktop environment (only CLI) and connected to my router (which I deactivated the DHCP) so the machine can act as a DHCP server. It works very well. However, I would like to install a few other utilities into that machine and for them to work, I need to put the machine between my cable modem and my router. Basically, here's the topology from outside):
Internet (ISP) --> Modem --> DHCP machine --> Router (no DHCP - acting as a switch) --> computers & printers
The problem is that I cannot connect to the modem from the computers on the network. Also I cannot access the internet (go on the WAN side) from the computers. From the computers (namely my laptop), I can ping the router, but cannot ping the interface where DHCP broadcast. Also I cannot ping the modem. From the router (using the web config page), I can ping the DHCP broadcast. From the DHCP machine, I can ping the modem. In the DHCP server, I setup the eth0 (the interface where the modem connect to) as a DHCP assigned IP so it can obtain the IP from the modem. The eth1 (the interface where DHCP broadcast) is static. All my machines obtains a IP from the DHCP machine without a hiccup.

Installed Fedora 12 recently.
For some reason, my network connectivity drops out randomly. This has happened between 5 minutes to 1 hour of booting and logging into the machine.
When the internet does work, its great, and super fast !
When it drops out, Internet stops working, cannot ping to external site and I cannot ping my router 10.1.1.1
I have onboard realtek network ports on my motherboard.

I have been using FC10, it works well with wlan for sometime and goes inactive after some time and hence network goes unavailable. Even after few attempts to reconnect doesn't help. Rebooting helps in bringing it back temporarily.

I just installed Fedora 10. I entered my static network info in Network Configuration. When rebooting, the eth0 says Inactive. I've read many articles about this problem on earlier versions and tried many of the suggestion, but have not found a definite way of solving this. Is there a better way or a workaround to get this machine on the network?
