Not Able To Connect To Internet Via 3G Router From Linux

I have several computers connected to a D-Link DIR605L router, two with ethernet cables and two through wifi. The Windows XP computer can see itself and nobody else. The Ubuntu (trusty) desktop and Ubuntu (lucid) netbook computers see nobody (unable to retrieve file list from server) and the Windows Vista computer only sees itself. Clearly, I have failed to configure something or a set of somethings.
Do I have to have one of the computers always on, acting as some kind of file server or can the router do this job? This is a new router. My old one (whose power supply went phut) connected everybody without arguing about it and we could share files around, even with a mix of OSs.
Since this is a local network only, I have no firewalls enabled, as far as I know ...
All of the network set-up posts I've found rabbit on about how to get your internet connection working through your router, which is not an option for me. I have dial-up working on the XP computer and a mobile wireless USB dongle for internet access on the trusty desktop.
I've installed samba and a few other packages, but so far, none of them have solved my problem. Can someone please tell me where to start and which tutorials to read? If I have to set up a computer as a file server, I guess it will have to be the XP thing, as it's the only one that is always running, but I'd like to avoid that, if possible, as I speak XP worse than I speak Ubuntu.
BTW, D-Link are no help at all, two hours on the 'phone and they were still trying to get me to connect to an ADSL service I don't have ...

Hello everybody,

I am seeking help regarding sharing internet connection. I would be greatful.

I have;
A Laptop : Samsung RV509, i3, 300GB HDD, 3GB Ram, Dual boot Windows7 & LM 17 cinnamon 32bit. WiFi & Bluetooth available. A Desktop PC : Celeron CPU 2.4GHZ, 40 GB HDD, 1GB RAM, LiveUSB-LM 17 cinnamon 32bit, No WiFi hardware available, No Bluetooth hardware available. A mobile phone : Nokia Asha 500, WiFi & Bluetooth available. An old USB data cable: with which the mobile phone can be connected to the computers. I have successfully connected and transfered data back & forth, and also shared/connected Mobile-Broadband-internet to both Laptop and Desktop.

What I have been doing now is; I have an internet connection to my Laptop with an external modem and Ethernet. Its working fine. I have an unlimited plan and so I want to share this internet connection on the mobile phone too; instead of incuring extra cost by connecting to the internet directly through the phone. I am successful at that. I can share this internet connection on my phone through WiFi.

Now, what I want to do is; without buying any extra hardware, to share this same internet connection on my Desktop PC, too.

What I tried is; I searched the web, but didn't find any solution. Now I am here. Please kindly help me.

Thank you & Regards

I am new to linux and My distribution is Kubunto. My wireless Icon shows that my connection to my router has been deactivated and will not allow me to connect to internet or give me an option to connect with a password. I cannot find the application in kubunto that walks me through the connection process. Is there such a program and what is its name. Thanks from a newbie

I want to connect a windows workstation to a rh linux network by a 35 meter network cable but it reads 10 Mbps speed and I can't virualize a physical redhat machine in the network
Is the problem with the windows, the cable length or I need to do some configuration in redhat.

Hello,

I am looking for a live linux distro that is able to recognize more hardware by "default" without installation. For example, when I borrow a laptop/netbook, I want to be able to boot the live linux distro and be able to have wireless access to internet (at least most of the time).

I know how to get the wireless working if I have internet access to begin with, but sometimes I do not have a wired connection or am not allowed to install stuff.

I would like to try many live distros on different laptops, but it would be hard to convince other people to give me their laptops to do that; so I would really appreciate your help.

Thanks

I am making the commitment to a linux server and am excited about all of the possibilities. One thing I was hoping for is network monitoring. My internet is not very good (DSL) and if an attached device decides to download an update it makes Netflix sputter and collapse. The problem is I have to check each device manually to see if the network drain is on my end or if it’s the ISP crapping out. This can be time consuming and frustrating.

Is there a program that can easily tell me how much information is being uploaded and downloaded onto the WWW? I fear this is going to need a router upgrade and my router won’t run DD-WRT or Tomato.

Thank you in advance

Have had ongoing problems with wifi since I built my PC. It was like it is now when I first built it, I tried bits I found online to try and fix it and evntually it just started working out of the blue, when I hadn't changed anything. A few weeks ago it just reverted to how it was before

Very rarely it works normally, except it will only see my network (always about 60-70% strength) and not the other 3 in range
Sometimes it will say it is connected but not be able to download anything, and wont even load up the router homepage
Sometimes it connect and run for a few minutes before dropping and not being able to reconnect
Most often it will see my network and all others in range but wont connect
Sometimes it wont see my network at all, but will see others in range
Sometime network manager wont even show wireless up as an option just "nwtwork cable unplugged"

My 2 HDDs are on Mint 17.1, one is 64bit one 32bit. Motherboard is Gigabyte GA-970A-DS3P. I have 3 wifi adapters, one belkin, one realtek, and one "Think Penguin" one I bought especially from USA thinking it would be an easy fix. All have same problem, but all work on my other older PC properly with about 50-60% signal strength (same OS 32 bit)

I have no idea where to start

is there a way via terminal to reset the username and password for my router?
i have recently started working with the terminal and in order to use ssh im going to need to download some software and enter the username and password for the router which i havent a clue what it is. im not sure i ever set the username and password on it????

if i could re make the username and password for my router i would then be able to get this ssh working.

or is this not possible?

The Internet connection icon in the notification area of my desktop panel shows the status of my computer's connection to my LAN and hence to the www – at least, it did from the date of first connection, in late 2013, until about December of 2014. It was infallible. Then, shortly before Christmas last year, router trouble on the LAN meant that no Internet service was available for the best part of a week whilst repairs/replacements were effected. Restoration of the LAN brought all four of my computers back on line (1 Linux Mint and 3 Windows XP) Ostensibly nothing had, nor needed to be, changed, as far as net connection addresses were concerned. The XP computers simply picked up where they had left off some days earlier but the Linux machine returned with a disabled LAN connection icon that has remained in that state ever since. Nothing else is affected, I continue to log on and off as normal and enjoy the same network services as before but nothing will now persuade the connection icon to change its disconnected state. If I right click the icon, and then click 'Connection Information', I get, “No valid active connections found,” which is at complete variance with the facts. I have used the 'Edit Connections' option but can find nothing apparently amiss. Wired Connection 1 appears to have retained its previous settings so the loss of function is a bit of a mystery. Anyone got any ideas?
