Anyone has difficulty in configuring the USB modem Huwaei 1260. I'm using photon plus broadband connection. Here's how I configured it.
Here the vendor id is 12d1 and the product id is 140b.
Now you have to do a modprobe.
Run wvdialconf as below.
Scanning your serial ports for a modem.
Found a modem on /dev/ttyUSB0.
The modem configuration will be written in /etc/wvdial.conf as below.
Make changes as below to the /etc/wvdial.conf
Run wvdial
Wow You are on to the net.
If your browser gives problems loading the pages add the nameservers in /etc/resolv.conf as below.
Then run the browser, there should not be any problems.

3G USB modem, in and using wireless router out (via ethernet) to lappy, Wii ect.We don't have a phone line just mobile phone and mobile internet because it is mobile.I have a wireless router only but need wireless to improve my standing within the house because I am seen as a net hog!
I did come across a Virgin wireless modem but it is soooo painfully slow (tested it against the USB dongle modem 3-4kb same test 1 min later 280-300kb's USB.) The wife could make herself a cuppa just waiting for the facebook login page to load!Would it need to pass on the connection bcause the USB is fully setup? then wireless is setup or would it be required to have a 3rd security setting ect in between?It would be good to use a low spec computer because I have a few. Headless too, maybe?

I have an Ubuntu server that I need to access remotely while I am at school. The server's internet connection comes first through a DI-604 broadband router and then through a Netgear Wireless router:
ethernet wall jack --> Broadband Router --> Wireless Router --> Server's ethernet port
I can manage to get the SSH to work with the current IP address (dynamic) by connecting the server directly to the broadband router, but I cannot set up DNS (ddclient on the server, Namecheap for domain registrar and nameserver) with it. I can set up DNS on the router with no issue, as it has the DNS client built in, but I cannot get the SHH to connect through both the modem and the router as mentioned above. Best case scenario, this can be fixed without having to get anything new, but if that is the case, recommendations of a new setup
Other reference info - ISP at server is Verizon Fios, broadband router set to PPPoE.

I just bought a TRENDNET TDM C4000 (=modem/ wiredrouter) and got it working. If I connect my computer with through the ethernet port directly, the internet will work. However, when I try connecting the ends of the ethernet cable on the modem and my wireless router, it's not transmitting. I know I set up the wireless router correctly because it worked with my previous modem. I just need to know how to configure my modem so that it works with my wireless router (D-Link DI-524).
I have a long wired ethernet wire to satisfy my academic needs for the internet at the moment but my mother is not able to surf the internet and it would be more convenient for myself to put the wire back to my desktop and have my laptop browsing wirelessly.

I use Opensuse 11.2 & Edge/Gprs Modem to connect Internet.I configured /etc/wvdial.conf & /etc/resolv.conf. Now I can connect Internet using this command "wvdial MYNET" in terminal.Now I want to share my internet using Lan card & Netgear Router. If i connect my PC with Router using wire & change option ON BOOT find this device in ifup then it'll show in ifconfig command.
My Router IP : 192.168.0.1 & It gives my PC an IP automatically : 192.168.0.2
I can ping my router.. even I can browse Router Admin page in browser. No problem there.But now If i want to connect my net using wvdial command... net connected... but no data passing!!! If i disable Lan card in ifup then Edge/Gprs net connection again OK!

I'm running Lucid xubuntu. i have a netgear WG111v3 usb wireless card. The router and the modem recognize each other,. but the connection drops constantly.Other times it takes many tries to connect. There are 3 windows and one Xbox users in my house, all on the same router. When I spoke with 2 different people at Radio Shack, I was told that the software on the router is Windows based, so the Windows modems get top priority over Linux, hence the dropped signals. I was advised I could do One of three things:
1. Buy another router, one that specifically recognizes every operating system. That way, we all get equal bandwith.
2. Buy an antennae that boosts the signal.
3. Buy a booster for the signal that one cable end plugs into the router,then the device into a power outlet; the other in any power outlet, and then hardwire that to my ethernet card in my computer, so the signal stays constant. This is the output from the terminal:
[Code]....
Based on this information, what would be my best option. I can't run line all the way across the house to my computer; that would take 50-75 feet after winding it's way through the house. I don't use the ethernet card although it's still in the machine. Could it interfere with the signal?

I have 2 machines both using U 11.04, one of them being Studio. I have tried to connect them together (via a modem/router of course) to browse files but I can't connect. I get error messages. I've installed samba and everything.

For my broadband Internet I have several computers connected by cable to a Netgear DG834Gv5 router which has its own firewall.I have the wireless turned off by choice.My desktop and laptop are Linux only. (Ubuntu lucid lynx) I use the same username and password (very strong password) on both.What I want to know is can I set things up so I can browse and copy files between the computers using say nautilus on either computer?if not nautilus then I would happy to be able to do the same via a terminal window.I am not necessarily wanting to be told how but either what to Google for or where to find it.

What are the pros and cons of various current model ADSL modem routers for use with DD-WRT, OpenWRT or Tomato? There are, of course, hardware compatibility lists (HCLs) for each of these (DD-WRT, OpenWRT and Tomato) but many of the models are no longer available and there are so many that researching them all would be onerous. Many pages on the Internet recommend the WRTG54L and that would be great but it is no longer an option except second user which is increasingly difficult. What are the pros and cons of the various chipsets: ADM5120, AR7, IXP4xx and BCM63xx?

I've moved a linuxbox from being my gateway (nat, etc) to behind a new gateway (a DD-wrt router). For transparency purposes, I'd like to continue using the old box services, and just have the gateway in front of it.
Here's what I did:
The newgateway is setup for class C, 192.168.0.0
This configuration works, but sometimes it doesn't and I haven't figured out why yet.
At sometimes, clients on the LAN get throughput rates with very little speed loss (using speakeasy speed test). They will run at 33M on the LAN, running through both the newgateway, and the oldbox, and get about 35M with directly connected to the cable modem.
Other times, it seems nothing can talk with anyone, and I am not sure why.
I know what I have done is a little unconventional, but it's a transitional thing, and I am not sure it is the cause of the problem, although it was the last things changed.

I have 2 pcs at home. I dont have a switch so I can connect only one PC at a time to my adsl router/modem for internet access. In the past I had successfully connected the two PCs (NIC to NIC) to each other using the same ethernet cable which was supplied with my dlink adsl modem.
Recently the motherboard of on of my PC went bad so I replaced it with a new one. The problem is when I connect the two using the same Ethernet cable they won't connect. The lights on the Ethernet port won't light up. I can still connect both of them to the adsl router (NIC to Router) (one at a time).

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 am thinking of moving the router behind a server and connecting the server directly to the internet via a modem. Are there any security issues related to doing this? or other things I should be aware of. Iptables are implemented on the server blocking access on unused ports.

I have a desktop computer (Ubuntu) connected to one of the LAN ports of the Cradlepoint MBR1000 router via an Ethernet cable. I also have a Verizon mobile broadband USB modem (USB760) plugged into the USB port of the Cradlepoint router.I also have a laptop (Ubuntu) with a wireless wi-fi adapter (802.11g). The laptop also has an Ethernet card but I'm not using it. The desktop computer does not have a wi-fi adapter, only the laptop does.
With the above setup, I have Internet access to both the desktop computer as well as the laptop computer, which I am well pleased with.Is there a way I can have file sharing between the desktop and the laptop, or at least ping between them, the way I have it set up? I can't use the ad-hoc method because for that to work each computer needs a wi-fi adapter. The router is using DHCP but can also be configured manually.

I have a CentOS server that has some problems with the network configuration. I can't find the correct settings / help on internet
The computer has 3 network connections. ETH0 is connected to a router (a FritzBox 7050 with IP address 192.168.178.1). The ETH0 card has a fixed IP-address 192.168.178.22 - gw 192.168.178.1. Firefox as well as the webserver are working fine. ETH1 is not working (and not activated) because of problems with the drivers. ETH2 should be the intranet connection. This interfacecard has IP-address 192.168.17.1 and is connected to a switch. After the switch I have 1 computer attached with IP-address 192.168.17.3 - gw 192.168.17.1 A ping from the server to this computer gives good results and a ping from the computer to the server also. trying to ping to the fritz-box or to the internet constantly fails. As far as I can search, I'm certain that the failing is caused by routing-problems on the CentOS server.
the command 'ifconfig' of the server results :
eth0 Link encap:Ethernet HWaddr 00:1E:E5:D5:F1:C4
inet addr:192.168.178.22 Bcast:192.168.178.255 Mask:255.255.255.0
inet6 addr: fe80::21e:e5ff:fed5:f1c4/64 Scope:Link

I use Ubuntu 9.04 Jaunty Jackalope.I have been trying to configure a NETGEAR DGN1000 modem router. my manual says that to access the modem for configuration, I should "Type URL... in the address field of [my] browser, and then click Enter."my browser, though, does not seem to find any such page and so I cannot continue the configuration. btw, we had no problem configuring another computer in the house running on windows vista, so that it looks like the cables are all in place, the modem and the line are ok.

I am trying to configure my ADSL modem/router. According to the manual it should go as this: For the initial connection to the Internet and configuration of your router, you need to connect a computer to the router which is set to automatically get its TCP/IP configuration from the router via DHCP.
