Fedora Networking :: Router Disconnects On Connecting 14 Machine?
Jan 5, 2011
I recently installed Fedora 14 on my machine. Ever since I cannot connect to the Internet at home.henever I plugin in the ethernet cable the ADSL router disconnects and all machines connected to the router lose connection to the Internet.
When fedora initially starts up, the network manager shows all the available wireless connections available to me. However, when I select my wireless connection, it will go through the loading process where it shows the two green dots and the circular moving blue streak, then it prompts me to put in the wpa password.
This is where the trouble starts...when i input my wpa password, it will proceed to attempt to connect to my network but it never succeeds in doing so--it will keep on asking me to input my wpa password. when i finally get sick of doing it over and over again, i just hit cancel instead of retrying to connect.
After i stop trying to connect, the network manager no longer shows all the available wireless networks--the list is completely empty, and i can find no way to get the list to show up again, with the exception of restarting my computer.
I am able to connect to the internet with a wired ethernet, but id like my wireless to work.
running Ubuntu 9.10 x64bit fresh install and updated.When I connect with my 3g um150 modem it disconnects my home network?? I cannot get them to run both at the same time and of cousre the next thing would be to share the internet connection.
I'm having issue with my wireless connection. I'm not sure if it is the WPA security causing the issue, but I randomly lose connection to the router. The network manager then scans for available wireless routers for a bit before trying to reconnect to my router and asking for my wireless password again.
I have two computers and a wi-fi router. A notebook with Ubuntu 10.04 and a desktop with Windows 7. Whenever the notebook is on, the desktop starts having horrible Internet speed, and eventually disconnects. If I turn the notebook off (or disconnect from the network) it starts working fine again. Both computers connect to the router via wi-fi. I should also note that the connection runs flawlessly on Ubuntu.
Hey all, I have got this strange problem with my Slackware server acting as router and gateway to my internal network. It randomly disconnects the WAN connection after X days ( it is between 2-7 days ). This error messages occured in /var/log/messages just before it lost its WAN connection:
Feb 20 14:36:00 tml dhcpcd: eth1: failed to renew, attempting to rebind
I dual boot Windows/Fedora 11 on my Dell Latitude D830 laptop, which has an Intel PRO/Wireless 3945ABG card and I have just bought a Linksys WRT160NL wireless router. I am currently trying to set up OpenWRT linux on the router. Because of the nature of my problem I have also posted this on their forum.I am having trouble connecting to my OpenWRT install via Fedora. Things seem okay in Windows, but when I try to connect from linux my laptop locks up completely and I have to hard reboot. I previously have never had any trouble connecting to any other router with this install of Fedora.
Running Ubuntu 11.04 on a Gateway LT3103U netbook. It's running fine except for that fact that when it goes to sleep (timeout or lid closed) or going into suspend or otherwise restarted/shutdown, my router restarts. It's a DLink DIR-655 that has been working fine until I changed this netbook to Ubuntu.After installing Ubuntu on the netbook, it found my SSID being broadcast and I added the connection by supplying the WPA2 password. I have full network access (local and internet).
It's just the router restarts and all my other machines lose connections. The router is using DHCP but supplying IPs based on MAC. Netbook is set to use DHCP.
I've had my PC connected to my router since I installed Ubuntu. My router has the address and name password for my ISP. I'd like to plug my PC directly into my ISP line, but the network manager won't find the connection, and I don't know how to tell my PC my ISP's address and the name and password to logon with. I set up my router, and I know how to make the connection in XP, but I don't know how to in Linux. I have very limited Terminal experience.
I have a computer running Ubuntu, and a MacBook Pro. I need to buy a decently cheap wireless router that I can hook up to my Ubuntu so that it will send wifi signals and I can use the wifi to go online with my MacBook Pro. I was about to get one today, but remembered how Ubuntu is picky about working with things like that. I'm only going to be using it to get signals around the house which isn't that big at all.
So what would be the cheapest and decently efficient wireless routers that I can use which Ubuntu will cooperate with?
When I start Ubuntu at work it automatically connects to the router every time. At home the router signal is quite weak but manually connecting via NetworkManager Applet 0.8 was successful for a week or so. In the past week, however, although the router appears in the list in Network Manager, it has stopped working and is unable to connect. Nothing has changed with the router or hardware in that time.
This is a new laptop which had Windows 7 pre-installed. Windows 7 connects to the home router successfully every time. I really don't want to use Windows 7 but until I can get this fixed I have no choice.
I don't know if it's relevant, but once I tried deleting the AUTO Home connection from Network Manager and was then able to connect on the next attempt, but this has not worked since.
I want to use centos as a developer server on my desktop before deploying my stuff to the internet.
I have a netgear DG834G router. It's IP address on my local network is 192.168.0.1 and connected to the adsl line. The router is set up to act as an dhcp server too. On the router I have reserved ip address for the nics per their mac addresses.
My server is on a dual boot desktop. The other boot is XP and works fine, picks up dhcp.
I don't know how to connect Centos to the router.
I have tried to play with the network manager but to no avail.
I can ping localhost, interface eth0 is there, but i can't ping to the router.
I have set the manager system/administration/network to get dhcp automatically.
I can't activate the eth0 although the hardware device says it is OK.
Ubuntu 10.10 connects to a DSL modem without any problems - I mean I just plugged it in and it worked - GREAT I bought a wireless router so I could connect my netbook and now my Ubuntu machine which is simply using a cable from the wireless router now DOES NOT connect. I tried a windows machine on the wired connection from the wireless router and it connects without a problem. OF course if I remove the wireless router from the chain, i.e. simply connect directly to the modem it works straight away.
I am using an HP dm3 1030us laptop. The wireless adapter is and Atheros 5009. I have a fresh and clean install of Ubuntu Natty in it. I am trying to connect to a Linksys WRT54G2 that is in G mode using WPA2 Personal with AES. Router info:
Router Information Firmware Version: 1.0.01 build 003, Mar. 26, 2008 Current Time: Mon, May 02 2011 20:34:37 MAC Address: 00:22:6B:4A:44:DF Router Name: WRT54G2 Host Name:
For several months I was using EDUP adapter with both my laptop that operated on Ubuntu 9.04 exclusively and a desktop that could also boot with XP. Soon after 9.10 was released I updated my laptop and was able to use the adapter to connect to the Net.Recently, I also updated the desktop but also made it exclusively a Linux machine. Unfortunately, I have been unable to get the wireless adapter to work again on the desktop.The OS recognizes the device as wlan0, and lsusb shows:Bus 003 Device 005: 0cde:0008 Z-Com Sitecom Wireless Network Adapter 100G+ WL -125The network manager recognises the availability of the wireless network and attempts to connect. After trying for a while it comes up with a dialog box "Wireless Network Authentication Required" and in response I enter the WPA password but with no success.The behaviour would indicate that I am entering the wrong password but I am not.I have checked it several times and compared with the password that works with the laptop.
I am having some bizarre problems with a 10.10 install which I am hoping someone here can give me a little input on. Some background info: I have a laptop which I had originally put 10.10 on about 4 weeks ago. I was using the Network Manager applet to change the MAC address by entering a valid MAC in the "Cloned MAC Address" field, and then connecting to a network. This suited me fantastically as the applet applies the MAC to any interface that connects - ie. the internal Intel card or the more often used external USB RTL8187L. For reasons which would take a lot of explaining (and now kicking ones self in the head) I had to install Windoze on the machine for a week to get some specific stuff done - but have now come back to 10.10.
The problem: So just as before, I installed 10.10, connected to my router (without changing MAC) installed system updates and other packages such as Macchanger etc and got the system working and customised how I like it. Problem is, now when I enter an address in the Cloned MAC address field and attempt to connect, the applet just sits there with the pulsing waves likes it's trying to connect but it cannot. Whilst this is happening, ifconfig -a shows that the MAC has indeed been changed. Until I remove the Cloned MAC address entry, I cannot hop on my router - or any other for that matter. Before, these steps were enough to ensure correct and functional cloning.
Things to know: This happens whether I am logged in as me or root. There is no MAC address filtering on 3 routers I have tested on (different brands). There is only MAC filtering on a 4th, and in that case, the cloned MAC is in the routers whitelist. This happens whether I specify IP details and if DHCP is used. All 3 routers without MAC control have been reset. All settings to do with wlan0/wlan1 in the network applet have been removed and re-entered. It happens on 2 different wifi cards (Intel and RTL8187L) but they worked before re-installation. I have also tried the usual commands in the terminal such as:
su ifconfig wlan0 down macchanger --mac (mac here) wlan0 ifconfig wlan0 up
also tried hwaddress ether 12:34:56:78:90:00 etc - The problem doesn't seem to be in changing the MAC, more the functionality of wlan0/wlan1 afterwards. I have also tried (although, it worked fine without this before) adding lines to /etc/rc.local and /etc/network/interfaces. It would be worth noting that either networking was restarted or the machine was rebooted after each alteration. No avail.
I can't think of anything significantly different that I have done to this re-installation compared to the first time, so I am not sure if perhaps in the time that it took me to reinstall 10.10, a package update has come out which has altered something and it's chucking a spanner in the works. Having said that, I even reinstalled AGAIN without applying any updates and same result. I would consider myself moderately experienced with Linux - so I am pretty sure that I am not making a complete n00b mistake... this situation is just so puzzling. I have been googling for quite some time and can find others with similar problems, but no actual solution.
I have installed Ubuntu x86 10.04 LTS onto an old Dell machine which is connected to my broadband modem and Netgear Wireless Router (WGR614 v6). The router is encrypted with 64-bit WEP and allows my System76 Pangolin Performance laptop to connect flawlessly out of the box. However, my sister runs Windows XP Professional 32-Bit on a Dell Latitude D830. This machine's wi-fi card is an Intel PROSet Wireless which recognizes the router but can't access it.
What should I do on her laptop in order for her to access the wi-fi router?
router comtrend CT-536T but now my laptop lenovo r61i is not able to connect to it. like it has a issue with wap/wap1. Is their a possibility to get it to connect. the other router maxG (US robotics) is wep/hex based. any suggestions ? It only made a connection the first time and after the signal wasn't even noticeable .
I have a Netgear DG834 ADSL router (v3) which I have used for a couple of years. Prior to that I had a v2 of the same router, but upgraded for the one that supports ADSL 2+ (here in the UK).
Recently I have been having problems with the connection often being dropped, and when I access 192.168.0.1 for the router admin page, when it is not working I get no IP address listed for that of the ISP's server, and sometimes as well the upstream and downstream speeds are listed as 0 kbps.
Usually this was resolved by rebooting the router.
However, for the last couple of days, when using Ubuntu 9.04, the page of the router at 192.168.0.1 will not load. I have tried numerous different browsers, and none of them will give the router admin page.
When I tried booting from a live CD of Fedora 13, the router admin page came up just fine, no problems (although still not getting a proper connection to the Internet).
I was going to try to use the older router I had, but so far, as I cannot access the router admin page in Ubuntu, I have not done so (not had the time, and now I am at work posting this).
So there must be a problem in Ubuntu that is preventing it showing the router's admin page. The Network connection details show that the router has given the PC an IP address of 192.168.0.6 and the DNS servers are listed, so I know that Ubuntu is talking to the router, but it is not allowing me to access its settings in any way.
sometimes our ADSL connection gives up and we are left without internet connection for days until the problem gets fixed. I mean by this problem along the phone line. It affects all machines that connect to the internet through a Netgear WIFI Modem Router. I recently tried an alternative when this happens is to use a USB Huawei Mobile Broadband UMTS connection which works when you insert it in 1 laptop. Is there a way i could get the Netgear WIFI modem router to connect on that usb stick or PC that is online on that usb stick and give access to other machines that will want to connect to the web ?
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.
i did googled for that for a while now, but didn't found anything relevant so far, or did i missed something? i need to share a pppoe connection, using an infrastructure wifi network, how can i do that in ubuntu?
forgot to mention, ad-hoc just won't do it for me, the other devices, either dosen't support it, either get a password error. also, i would need some help for establishing the pppoe, i previously did that on another machine, but that was long ago, and it was a big head ache, it would only dial on startup, and no redial or disconnect posibilities whatsoever.
I have enabled IP Forwarding in my linux machine by using the commandsysctl -w net.ipv4.ip_forward=1. But I dont see any difference in routes when I type the route command before and after changing this value.Do you guys have any solution to verify the packet forwarding, but using this single linux machine only? Of course, I verified the net.ipv4.ip_forward=1 value. But I need to verify by transmitting orreceiving packets
I have WiFi router at home and connected two computers running ubuntu linux connected to it. One connected through WiFi, second through LAN. So what is the problem: I can't SSH from Gnome terminal to any machine. Be it local computer on the same router or be it distant computer. SSH session hangs just after successful login. I've read a lot about it and it should be related to DNS, MTU or whatever, but not in my case ! PuTTY client works without problem to local or to distant PC. SSH session from Gnome terminal works also just fine if.... I connect two comupers directly by not using router. So it seems SSH installation is ok, configuration is ok, but somehow router is not ok. I looked at packet sniffer of router itself and I see that packets successfully go from one computer to router and then to other computer and returns back. Firewall working ok. And its not about packet forwarding because I have the same problem if I try to SSH to router itself.
So the question. What theoretically might be wrong with router packet management ? Why PuTTY and Gnome terminal SSH packets differs ? What is the difference ? Where should I search for some sollution? I ran SSH in debug mode, but it was no so informative. It successfully logins and hangs on this line: Code: channel 0: open confirm rwindow 0 rmax 32768
I'm trying to connect to an XPpro machine using terminal server, I've been to the microsoft web sight and configured xp as they explain. Which consists of "allow remote desktop connections" and "re configure the fire wall", Done. I've obtained the ip address of the router and the user name and password of the xp machine and still I cannot access it!
