Ubuntu Networking :: Slow Wifi - But Fast Connection On Network Cable

Jan 22, 2011

I have a strange problem that I cannot diagnose -- slow wifi. About two or three weeks ago, I noticed that my wifi began to slow down dramatically. The problem is the same on my ubuntu laptop and my ipad. But when I connect directly to the router with a network cable, my connection is fine. So it is definitely a problem with the wifi signal itself.

What I have done so far:
(1) I checked all of the MAC addresses connected to my wifi. I identified my tivo box, laptop, and ipad. Nothing else.

(2) I used [I]wifi analyzer[I] on my android phone and selected an unused wifi channel (channel 8).

(3) I changed the username/password on my wifi signal. I also changed the password for my router's admin privileges.

(4) I restarted my router and computer.
None of this helped.

I am using a Netgear WGR614 wireless router.

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.

General :: Networking - Impossible To Run A Network Cable

Dec 16, 2010

I have a Verizon wireless/wired router that I access the internet through. I have a desktop computer running Slackware 13.1 i386, but it is in a place where it would be impossible to run a network cable to. Would you buy a USB wireless card? Would it work with Linux? Is there another way I can get my computer networked that I am not thinking of?

Networking :: Sharing Network Using Crossover Cable?

Feb 14, 2011

At the outset I would like to tell everyone that I am still relatively a newbie in linux. I use a usb mobile broadband data card to connect to the internet, and I recently purchased another desktop for my wife. Both of us do not share any files, but I do not have a router and was wondering if I could share my connection with her using a crossover cable.I did a lot of Googling around and tried various different things, I even followed another thread in the same forum but the most that I have got is my network manager saying that connection has been established. I am however not able to see her computer under my windows network and don't know how to proceed.I don't know where I am going wrong, and considering that my knowledge of networking is at below basement level, I would really appreciate any help in this regard.

Networking :: Network Cable Just Stopped Working

Dec 14, 2008

I have a laptop, and the wireless and cable worked fine for a while, but one day, for some odd reason, the wireless and network cable just stopped working. I'd connect to the web, and I would get output using "ifconfig" and the GUI wireless signal. When I hook up the wire, it detects it. However, no matter what I can't load any web pages. The wire does work in another house, and my windows partition utilizes these devices well. Any ideas?Additionally, I am able to log into my wireless router and change configurations, but that's about it :/.

Ubuntu Networking :: Sharing 10.10 Network With Win7 Over Cat5 Cable?

Mar 6, 2011

Im a long time Ubuntu user (since 5.04), but networks were never my speciality, I have a desktop running 10.10, connected to the internet trough a US robotics modem (connection eth1), and i want to share its network with my laptop running win7, over a cat5 cable (connection eth0), but the problem is I dont seem to understand what i am doing wrong, what the missing steps required, or in which end is the problem (either ubuntu or windows side).

From what I could grasp was needed googling about the subject, i already set the eth0 connection to share with other computers (in network manager edit connections auto eth0 ipv4 configuration set to share with other computers). Also using the cli set eth0 for static ip using :

Code:
sudo ifconfig eth0 192.168.0.1 Now the question is what i am missing? or is everything needed already done and i just have to properly configure the win7 side (which i already checked several times)?

Here is my ifconfig output:

Code:
eth0 Link encap:Ethernet Endereo de HW 00:01:29:a6:55:fe
inet end.: 10.42.43.1 Bcast:10.42.43.255 Masc:255.255.255.0
endereo inet6: fe80::201:29ff:fea6:55fe/64 Escopo:Link

Networking :: Using Ethernet To Power WiFi Network And Setting Up WiFi?

Aug 23, 2009

I have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.

Networking :: Ethernet Cable And Wireless Network Won't Work In Ubuntu 9.10 / Sort It?

Feb 20, 2010

I'm a new user of Ubuntu, so i'm not that familiar with this OS. My wireless network is detected but when I'm entering my 128 bits WEP key, it doesn't connect at all. I have no clue where to start troubleshooting.

Here's some of my specs if that's of any help:
Computer is a Sony Vaio laptop model VGN-SZ370P
My wireless card is from Intel Corporation 82801G (ICH7 Family) USB UHCI Controller

The ethernet cable connection used to work before, but I fooled around with some commands and now seems to be disabled...

Ubuntu Networking :: Network Manager Replaces Default Route When Eth Cable Plugged

May 5, 2010

I have been encountering this problem, not only on 10.4, but on older versions too: I use a wifi router to connect my laptop to the Internet, but sometimes I need to connect directly to another computer to move some files over GLAN. But Ubuntu's Network manager doesn't allow me to configure the eth0 interface without specifying a gateway (no gateway = grey submit button), but when a gateway is specified, it always rewrites the default gw specified already by the active wifi connection and returns back after unplugging the eth cable.

Of course this can be solved by a few route commands, but this is unacceptable since it is needed to establish the cable connection without any further assistance from within and as well without replacing the default gw and thus breaking the Internet connection. Is there, please, any possibility how to prevent Network Manager from replacing these routes?

Networking :: When On The Network, Can See The Shares Just Fine, But If Use A Crossover Cable, Cannot See Or Access The Folders?

Mar 3, 2011

I have a home network and I use Samba to share files. Now when I am on the network, I can see the shares just fine, but if I use a crossover cable, I cannot see or access the folders or files.My goal is to use a crossover cable from one computer with clonezilla to my server in order to use Samba to make an image of my workstation and save the image on my server.But everytime I try to connect with clonezilla I get a persmissions error and the share will not mount. I tried going to the shell and mounting as root, but that did not work either.

I have another server which is only a console and it works though I am unsure why. The share though is a mounted usb drive while on the one that does not work, it is on the internal hard drive.I was wondering if anyone had any ideas or anything I could try to narrow down the problem. Oh, I can access the share using ssh, but not samba. One other thing, the shares are set to allow read/write access to everyone so I don't see why I can not access it.

Ubuntu Networking :: Way To Ban A Wifi Network In Network Manager

OpenSUSE Hardware :: USB Wifi Adapter Works When Connected Directly But It Doesn't With Cable

Jun 4, 2010

I am using this usb wifi adapter, it uses zd1211rw and it works fine if I connect it directly to the usb port, but if I add a cable (around 5mts) between the usb port and the usb plug, the device doesn't appear (I used iwconfig to check). The green light on the wifi adapter turns on but it doesn't blink like it does when connecting it directly without the cable. What could be happening?

I use the same cable + usb wifi adapter in windows, and it works fine, I can scan and connect without problems. When I use the cable, lsusb doesn't show the device neither, it does when connecting the adapter directly.

Ubuntu Networking :: How To Choose A WiFi Network

How do I choose a wireless network to connect to? The Ubuntu 8.10 help tells me to open NetworkManager, but the only thing I can find is 'Network Configuration' in System>Preferences. If I try to run NetworkManager in usr/sbin as a root, nothing happens whatsoever. nm-tool lists several available Access Points for my WiFi antenna.

Ubuntu Networking :: Can See My Wifi Network - But Can't Connect

Feb 18, 2011

So recently we switched Internet Providers. While we had Bellsouth, my laptop would connect to our wireless internet flawlessly everytime. However, we just switched to Charter because it was both cheaper and faster. But now, my laptop will not connect to our wireless. If I hook it up to an Ethernet cord, it connects just fine. I believe they gave us a new modem/router or whatever it is that sends out the wifi signal.

I have tried to connect with this laptop on Ubuntu, Linux Mint, and Backtrack 4. On Ubuntu and Linux Mint, after I enter the correct WEP key, it sits there and tried to connect for a minute or two, but then the window pops up asking for the WEP key again, even though it's still filled out.

When I tried connecting on Backtrack, it told me that it could not obtain an IP address.

Ubuntu Networking :: WiFi Network Won't Load

Mar 3, 2011

when it boots it doesn't ask me for my password (not the one to WiFi network, but the one to 'default key base') and because of that I can't connect to my WiFi network. The network itself is working fine. So i restart my computer (sometimes I have to restart it 15-20 times) and finally Ubuntu asks me for my password I type it in and everything works fine. what should I do with this?

Ubuntu Networking :: Can't Connect To Wifi Using Any Network Manager

Dec 26, 2010

i was fed up after i can't connect to wifi using ubuntu. the problem happened after my router is being replaced to a new one because the old one got struck by lightning. good thing i dual-boot my laptop so i can access the internet using Windows 7 now.

i use the default network manager to connect to wifi before, but it all seem to be failed after the replacement of router. i also used Wicd but it failed to connect either. it says in the notification "disconnected: bad password" but the password was right. my wifi used WEP password with open authentication.

i even remove the WEP password and try to connect, but it failed. all i can do is to boot in windows 7 and surf internet there. what could cause this problem? is it the router, the telephone line? i can set the router settings if i want, but i don't know what causes the problem.

Ubuntu Networking :: WiFi Network Connection Started Failing

Sep 1, 2010

My ubuntu system has been running really well until this morning - software update prompt appeared on the screen, so I ran with it and let it do its thing. A while after this, my WiFi network connection started failing. I've tried rebooting and then it can take up to five minutes or more for the password (keychain) prompt to appear. Once I have typed in the password the network connection starts to work. Then cuts out. Works. Then fails again.

Ubuntu Networking :: Campus Wifi Network Not Showing Up In Maverick?

Oct 12, 2010

I upgraded to Maverick over the weekend from Lucid, and at school yesterday, I could no longer connect to the campus wifi network in my office. I have no problem connecting to the wifi network at home, and my phone still sees and connects to the campus wifi network, so I think the problem is with my laptop (Gateway T-6345u), which doesn't even detect the campus network. As of last week, it connected automatically, and now it can't even see the network.

Ubuntu Networking :: Maverick PC Will Intermittently Kill Wifi Network

Nov 15, 2010

This week I did a fresh install of Ubuntu 10.10 on a newly assembled PC. The hardware I am using is below.

My wife has a Macbook with built-in Wifi connected to our Linksys router. Previously, the connection would drop 0-2 times a day. She would turn off Wifi on her Macbook, turn it back on, and it would reconnect immediately.

Since getting my Ubuntu PC, these disconnections have become more frequent, every 30-90 minutes. They effect both computers simultaneously. And now, I MUST turn off Wifi on my Ubuntu box to regain the connection. Switching it off and on with the Mac doesn't help. Unplugging the router doesn't help. I have to run upstairs and uncheck "Enable Wireless" on the Ubuntu Network Manager outlet.

The connection doesn't seem to drop if the Ubuntu PC is sitting idle. But it can happen with web surfing, Samba file transfers, or torrent downloading.

I noticed that Encore has a linux driver for my card called RT2860. It looks very difficult to install. Ubuntu automatically uses RT2800. So I don't know if this could be a driver issue. Also, shouldn't my bit rate be more than 1Mb/s? Both the router and the card are 802.11n. Are the dmesg errors something to be concerned about?

Machine Brand and Model (PC/Laptop): Self-built Desktop. AMD Phenom, Gigabyte motherboard. Router Brand and Model: Linksys Wireless-N Broadband RouterWRT160Nv2. (I already updated the firmware to the most recent version)
