Ubuntu Networking :: RT2500 Does Not Connect

Mar 19, 2011

I installed Ubuntu 10.10 on my old laptop the other day, but it seems that Wifi card is having some troubles with co-operating The wired connection works like a charm but I'd prefer wireless on the laptop....I know the laptop is an oldy (PH Easynote R1904)


here's the LSPCI output:

Ubuntu Networking :: Ralink Rt2500 USB Adapter And WPA?

Jan 22, 2010

I have a rt2500 wireless USB adapter ( WLI-U2-KG54-AI ). I tried to use it on 2 computers loaded with Ubuntu 9.10. It worked well in WEP mode, but I am now trying to connect to a WPA router and the connection fails (the network manager icon keeps rolling forever). WPA works well on those machines when using another wireless adapter (not rt2500 based). This adapter also works well with WPA under windows. Is this device supposed to work with Ubuntu in WPA mode

Fedora Networking :: F9 And RT2500 - Card Works But No IP Address

Mar 30, 2009

I have an auxillary laptop that I use with Fedora 9 on it. Up until now, I have been using wireless just fine with a an old Marvell card. A friend needed a wireless card, so I gave it to her because I had a spare Belkin card (PCMIA) with a RT2500 chipset. This chipset has been supported in Fedora for a long time, and it does it fact work but it will not obtain an IP address and disconnects from the Network Manager upon every attempt to connect.. I get an error that says "set bit rate" failed and I cannot get assigned an IP address from my router.

I do not use encryption. Nothing I have tried with sysconfig-network has had any affect.

iwlist scan finds the router just fine with a good signal, but will not connect.

Fedora Networking :: RT2500 Wireless Access Point Not Showing Up

Jun 23, 2010

I'm new to Linux and I have a problem with the Wireless connection.I've already searched for this problem but found so many threads it was impossible to sort it out.I've just installed Fedora 13 (Live CD - Install to Hard Drive) and apparently it's kinda... "empty". But my problem is with the wireless connection. There is a free network provided by my city for all the citizens. It is Open (authentication) for all. The problem is I can't "see" the network in Feodra. In Windows 7 I can "see" it just fine with 3 bars signal strength. It is great for surfing and emails. It is not intended for heavy downloading.

Why can't I "See" this network? There is another weird thing. The neighbor above me has a Wireless access point closed of course but I get 44% signal strength in Fedora and Full bars in Windows. Does it have to do anything? Maybe the low signal of the free network is the problem and Fedora makes it disappear completely?

Ubuntu Networking :: Slow Wireless RaLink RT2500 - Compared To My Windows Laptop

Feb 27, 2010

My wireless on my Ubuntu desktop is really slow compared to my windows laptop. Its not a flash problem or a browser specific problem.

I have searched the forums but can't find much.

I did disable ipv6 (it now shows up as being 'ignored' in network Manager which is correct, right?) but that hasn't helped.

It doesn't make a difference whether I use DHCP for everything or just for address only with the Google DNS addresses.

After entering 'lspci' my card shows up as


Because of a problem with system freezes I have updated to the 2.6.33-020633rc7 kernal but this hasn't had any impact one way or another on wireless speeds.

My router is a Belkin WRT300n.

Ubuntu Networking :: Unable To Connect To The Internet But Can Connect To The Router

Apr 6, 2011

I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.

Ubuntu Networking :: Internet - Cannot Connect - But Can Connect Through XP On VMware

I had put my computer on standby and when i restarted it, it powered off within a few seconds. I turned it back on and after that i've lost connectivity to internet on Ubuntu 10.04.

However I have VMware (XP) installed and internet/network works on that. I'm a newbie with Linux.

Here are some outputs:

I have tried to edit the connection using System>Preferences>Network Connections. I entered manual settings for IPV4, but whatever i enter there, it doesnt get reflected when i type ifconfig in the terminal window. I tried setting it to Automatic DHCP as well. Doesnt work.

Networking :: Kubuntu - Can't Connect To The Internet But Can Connect To The LAN

Nov 12, 2009

I've recently set up a local development webserver using Karmic Koala. I downloaded and installed the server version of Kubuntu and have the web server working.

The problem is that for some reason, I'm no longer able to connect to the internet. I can connect to my router, and other machines in my network can VNC into the server.

I'm using an wired connection to the router and have the server set up on an internal IP of I used to be able to connect to the internet, I downloaded and installed a load of packages etc before it stopped working.

The last thing I remember doing before it stopped working was that I installed Samba so I could share files with the other machines on the network (two Macs running Leopard and a WinXP laptop).

I got the share working - I copied a load of files to the server via the share, rebooted, and for some reason now I can't connect to the net (and other machines can't see the Samba share either.) However I can still VNC into the server.

Networking :: 3 Nics - Connect To Internet - Share To Local Net - And Connect To Local Net - Not Working

Sep 15, 2009

I have a Dell PowerEdge 1650 server with 3 NICs in it. I am trying to use one NIC (eth0) to connect to the internet, the second NIC (eth1) to share the internet connection to a LAN, and the third NIC (eth2) to connect to the LAN.

It is running Ubuntu server 8.10

The problem that I'm having is that NetworkManager (version 0.7.0) keeps setting eth2 as the default connection, and then I don't get any internet at all from the server.

My main goal is to be able to share files from the server to computers on the LAN. The secondary goal is to have a virtual machine hosting a Halo server, connected through eth2, so that it can host LAN games. But that is a secondary goal after I get the connections to work.

I've been looking around and finding other people who have done bits and pieces of this, but not the whole thing. I had been hoping to simply use the NetworkManger, but I don't mind editing config files.

Also I can't seem to find any good instructions on editing the /etc/network/interfaces file. The man file is incomplete, and everything seems to point back to the man file.

Ubuntu Networking :: Cable Modem Networking - Can't Connect To Each Other On The Home Network

Feb 14, 2010

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.

Ubuntu Networking :: Unable To Connect To A Small Number Of Random Websites: Otherwise Networking Is Fine

Dec 29, 2010

I was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net. Got the following: Quote: Firefox can't establish a connection to the server at internode.on.net. or Quote: Oops! Google Chrome could not connect to internode.on.net

As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)

ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:

Fedora Networking :: Networking - Connect To The Internet Using BSNL Broadband Connection

Mar 6, 2010

I have installed fedora 12 recently. after installation i tried to connect to the internet using BSNL broadband connection. I filled in the details such as IP, Netmask, Gateway and even DNS servers. In the services also I ensured that the network manager services is on. However even though my computer cannot connect to the internet. I then tried the ping test of the modem from the address and found that the ping test is successful. Then i tried the network administrator and there I noticed something unusual.

There are two options in the devices eth0 and eth1 thats ok but the unusual; thing is that the Activate (green button), Deactivate (red button) and even the delete buttons are in the background and I cannot select them. Isthis the problem for the network connectivity.

Networking :: Networking Script Doesn't Allow Local Machines To Connect To Each Other?

Jan 21, 2009

I wanted to be able to have separate NICs with separate IPs connecting to separate gateways on a machine so I could put an ftpd on each one. I tried binding an ftpd to each, and running separate instances of the ftpd. I tried virtual hosts.

NOTHING worked. I could either use one ftpd or the other. I could either connect via ssh on one IP or the other. the second I turned one NIC off stuff would work again. I messed with basic iproute commands, andnothng worked until I got this script to run, which allowed me to use each NIC independant of the other.

#ip route flush all
ip route del default dev eth1
ip route del default dev eth0
ip route del table 1
ip route add table 1 to default via dev eth1

But now, samba client doesn't work. cifs mounting doesn't work either. It can't connect.

BEFORE I ran that script, I could connect via ssh, or to the ftpd running on the machine using a LOCAL IP - AFTER, I have to use the external IP, or I cannot connect. I know that has something to do with it, but I do not have the advanced linux routing knowledge to redo the script or come up with a solution.

But as soon as i select MPPE the option to select PAP is grayed out! I can't have both!
