Every time I connect to the internet via pppoe the OS freezes. Note that fedora 14 does the exact same thing, freeze on network connect. Both are are x64 variants and the pppoe connection worked fine on live bootup.
On the other hand Windows 7 boots and uses the connection just fine.
NIC - TP-LINK TF-3200 10/100 Fast Ethernet Adapter on a PCI port.
We have an old Zonet 10/100 switch in our home network that locks up whenever there's a power glitch longer than about a microsecond. (OK. It's not that bad but if the lights flicker, I usually end up going down to the basement to see if the switch is hung.) None of the computers or peripherals are affected by the glitches, BTW. Power-cycle the switch and everything starts working again. After putting up with this for months I finally picked up a Netgear 8-port 10/100/1000 switch to replace the Zonet. Unfortunately, when the Netgear switch is in the network, everything slows to a crawl before completely freezing up. Pinging other systems barely worksname would not work.Pinging another system by its IP address worked a little but packet losses of 70%-80% were the best I saw. At first. Then it gets to where the loss is 100%.
All systems were rebooted after the Netgear switch was inserted into the network. The systems that were capable of gigabit connections autosensed the new switch and set their port speed accordingly. And that's about all that works when the Netgear switch is present. (The Zonet is back in the network now.)One thing I have not tried is forcing the port speed on the gigabit-capable systems to 100Mb and re-inserting the Netgear switch into the network to see if the problem if due to running some of the ports at 1000Mb.The systems on the network are running various versions of Linux (with different kernel versions, of course). Most are due for upgrades to get them current but I was planning on hitting the systems that had gigabit-capable ethernet interfaces thinking that a.) 100Mb speeds have been around forever and no problems have been seen when everything was running at 100Mb in the past and b.) the gigabit support for the older kernels should be better (one system only supports an MTA of 1500 max at 1000Mb).
Since I upgraded to Ubuntu 11.04 my system freezes when I plugging-in an ethernet cable.My network devices:

I can connect to the internet through wifi, but I cannot connect to anything on my network. I have a printer and a NAS, so I would really like for this to work again. I have a dell laptop with a Broadcom card.
View 9 Replies View RelatedI recently fixed an annoying problem and I thought it would be nice to share my solution here. The problem was that after a cycle of suspend/resume, Network Manager would only auto-connect to the same network as it was previously connected to. So, for example, if I suspended my laptop at home, and then I went to school and resumed it, it would try to connect to the home network, and then just give up. It would not connect to the school network unless I explicitly told it to.irst, I'll describe the fix. If you're having this problem, you can this. Copy the following:

I have used ubuntu in the past but had a lot of hardware issues with it and unfortunately moved back to windows (( BUT i have tried Ubuntu again and all seems to work great except wifi My wifi connection is sort of working because when i run SUDO IWLIST SCAN it does pull up all available networks. But in the network manager icon on the panel i left click but i see no networks and can't connect to anything. I WOULD LOVE TO keep Ubuntu and use it permanently but I must get wifi working or else this won't be possible.
View 4 Replies View RelatedI recently put Linux on a Thinkpad T40 I got. The wireless card works out of the box--I can see nearby networks. However, I can't connect to mine. network-manager would try (spin spin spin), fail, ask for the password, and then go back to the beginning and repeat indefinitely. This happened to me on a different computer, and on that one all I had to do was use wicd instead of network-manager. So I installed wicd, but it's not working either--it hangs at "Obtaining IP address".
I've found many, many threads with people who had the same problem, but none of their fixed worked for me.
I also tried to get wifi going manually, using this guide, but that didn't work.
I'm unable to connect to a particular home wireless network under Fedora 9, although I can connect to it using WinXP on the same machine. My Fedora installation is able to connect to my college's unsecured wireless network, so it's not a driver issue I think.It seems to be an authorisation issue, as I'll describe below, but there's one other thing that's bothering me. The SSID for the network I have problems with is for some reason not listed in Network Manager's drop-down list, nor is it in the output of iwlist wlan0 scan. But I'm pretty sure it's not a "hidden" network - I don't know exactly how those work, but I helped the owner of the wifi network in setting it up, and don't remember doing anything that would make it hidden. As far as I can remember, Windows found the network automatically without having to be told the SSID. What's the best way to confirm whether it's a hidden network or not?
Anyway, I try to connect by selecting connect to other wireless network in Network Manager, and entering the SSID. As far as I can tell from the error messages below, the machine does contact the network and attempt to connect, but I'm not authorising myself properly. That may be a completely wrong diagnosis, but hopefully someone can see from the below info whether it's correct or not.I'm not sure which option to use for "Wireless Security": at the time we set up the network, it gave us a Hex WEP key of 26 characters, which is 104 bits. But none of the options in Network Manager's list match that. Here are the options it has, and the error message I get with each one:None - if I select this, it fails to connect, with no error message.
WEP 128-bit passphrase - if I select this and attempt to use my 26-character WEP key, it brings up a new dialog, saying "Passwords or encryption keys are required to access the wireless network [SSID]." It has a drop-down box labelled "Wireless Security", but this time the only option is "None", and the connect button is disabled, I can only click cancel.
WEP 40/128-bit hex - as above.
WEP 40/128-bit ASCII - The connect button is disabled when I try to use the WEP key, as the string is too long. Despite the fact that it says 40/128-bit, it actually accepts 5 and 13-character strings (40 or 104-bit). Since I've got a 104-bit hex key, I tried converting it to ASCII, but it consists of mostly unprintable characters, so I'm not sure there's any way to actually enter it into the textfield. I might have done something wrong here, so I've put my code below to see if anyone can point out a mistake.
LEAP - requires a username, not applicable here I think. Windows doesn't need one, and we don't have one from when we set the network up.Dynamic WEP (802.1x) - requires username, private key and various other things, all N/A WPA & WPA2 Personal - Brings up a dialog with the same text as for "128-bit passphrase", but this time "WPA & WPA2 Personal" is the only option in the drop-down list, instead of "None". It asks for a password, so I just enter the hex key again - now it asks for the password for the Gnome Default Keyring, which I don't think I've ever set up. Don't know if I can go any further with that, but my understanding is that since we were given a WEP key when we set up the network, WPA will be N/A.WPA & WPA2 Enterprise - as Dynamic WEP. N/A.Hopefully that's enough info that someone can help diagnose the problem. Some of the behaviour of Network Manager described above doesn't make sense to me, and I'm wondering if it's buggy.
I just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.

I wasn't able to connect to my WPA secured network. This was because there was no network in the list to connect to. I installed ndiswrapper, and installed a Windows driver. Blacklisted the old one and yes. This worked. Then the next morning exactly the same problem. I tried to repeat the same process. To bad. This time it didn't worked. I removed the old driver from the blacklist. and tried to update. No luck at all.I searched the forums.

I have 2 systems running ubuntu - 1 Karmic and one Lucid - that I am having problems connecting to my wireless network with. On both systems I am trying to use the same USB wireless dongle - a Linksys Wireless G 2.4Ghz 802.11g. On both systems it picks up my network (amongst others) but will not connect. I try to connect, enter the password/key and it processes for a little while an then just comes up with "You are now disconnected...".
I have a BT Homehub (gen 2 I think) which is set up to use WPA/WPA2 (from memonry). I did try downgrading it to WEP and got connected (only tested on one machine) but dont much like using a less secure system.
So I fall upon the mercy of those who are better than me to try and guide me through this. I have looked into it on the forum but couldnt really get my head around the problem.
Give me some info on where to start and how to diagnose the issue?
Just in case anyone wonders - we have a laptop running karmic (im posting this on it now) that has no issues connecting so the network is accessible. I assume the problem I have lies with the linksys adapter and the software using it.
Linux-user, but this has got me scratching my head. I followed this on how to install and configure the DWA-140 to work with Ubuntu 11.04, and "iwlist scan" outputs all of the networks. When i try to connect to my network however, the icon up in the right corner with the signal bars just keeps on going until it prompts for a password to join the network. I enter the password and it goes on for some time, and then it prompts me for the password again.
I'm using a D-Link DIR-655 with the "Only N" mode active. It works fine on other computers (Windows, sigh) but not on my Ubuntu one.
I install 11.04 in my laptop, and now i wana test the 11.04 in my office network.We have a server, that shared the database off our programs in a SAMBA drive. All the others workstations have windows instal and use that databses to work in the programs we have.What i'm traying to do is conect my 11.04 to that network, share files with the others PC, and work in the programs i need like in a win worksation tru wine/crossover. My main problem is that i don't know how to conect to the network and see the other workstations.

up until about four days ago connecting to the local LAN was as simple as booting Ubuntu, and letting nm-applet automatically connect on Auto Eth0 But the other day it just randomly stopped working, with no cause that I can think of. I can still connect to the internet (This is via a PPPOE connection, running through the same wired interface) so it can't be a hardware problem with the ethernet port/cables themselves. nm-applet just stays spinning in circles, and nothing ever happens. I tried deleting the auto Eth0 entry, and creating another LAN entry with exactly the same settings, but I still get the same problems. way to completely restore nm-applet settings? Or some other way to give me access to the local network?

I just wanted to share how I got my wireless network working after spending several hours doing it wrong. It might be helpful to others.My wireless router is set up as a "hidden network". That is, it doesn't broadcast the SSID to prevent hackers. My laptop connected fine under Windows, but not Ubuntu.Lots of posts told me to do stuff in the Network Manager. I tried, but I couldn't find the right settings. It turns out there are *TWO* different programs that control the network settings. I was using the wrong one.
To get to one of them you go to System/Preferences/Network Connections. This program is *NOT* Network Manager. Whatever I tried to set up in this program, I could not get a working connection. The other program, the *REAL* Network Manager, is a different program altogether. You get to it by clicking the network icon at the top right corner of the screen. The problem is you can barely see it if the network is not working. When the network is down, all you can see is a tiny greyed out triangle. That's the thing you have to click. After I clicked this and followed the steps under "Connect to a hidden network".
