Use "USB Modem" (3G) For Internet And LAN (Ethernet) At The Same Time?

Oct 7, 2011

Where I work, need to be connected to the LAN (Ethernet) in order to access remote servers, however these networks do not have Internet access. To access the internet I use a "USB Modem" (3G).Question: I want to use the "USB Modem" (3G) for Internet and local area network (LAN) (Ethernet) at the same time.Problem: Windows 7 not let me do this, since when I plug the "USB Modem" (3G) the LAN (Ethernet) is disconnected.Note: They suggested me to create "a bridge" between the two networks, but this option is not available even if I release all shares in connection "USB Modem" (3G).

Using WiFi And Ethernet At Same Time?

May 2, 2012

When both the wireless NIC and the physical Ethernet NIC are both connected to a network that has an active Internet connection, which one will the host use for network data?

Will it randomly use both to get data, or will it choose the faster connection?

USB Modem Not Connecting To Internet

Nov 13, 2010

A few days ago i was trying to connect my laptop to my ps3.To do this i was changing setting etc but never got it to work anyway.The next day i turn the computer on and can't connect to the internet.I think it was something to do with dns.I uninstalled and reinstalled my usb modem and software and always get full connection bars and says its connected, but in the bottom right hand corner it says network "no internet access" with a yellow triangle over it.It was because i was changing all of the settings in network and sharing senter, but being the wally i am, never wrote down the original settings. Whatever i did i am fairly certain i did it in the change adapter settings.

Can't Use Ethernet Network Connection And USB Wireless At Same Time

Nov 2, 2011

In our office we have our PC's connected to our inter-office network server via the Ethernet ports (Local Area Connection) with a hard wire to a hub, that in turn runs to our server. We also each have a wireless internet connection on our PC's via a USB wireless adapter. When we were using XP this was not a problem to have access to the server AND the internet at the same time.

When my PC died last year I bought a Dell Inspiron 560 slim tower with Windows 7 to replace my XP machine. The first problem I ran into was that I could no longer use the wireless internet connection AND the hard wired connection to our server operating at the same time. If I stayed connected to our server, I will not have a wireless connection. If I go into the "Local Area Connection" properties and "disable" the connection, I almost instantly get my wireless connection back. The big issue when doing this is if I leave our database program (ACT!) open while the server connection is disabled, I have to shut down ACT!, then restart it before I can connect it to the server. If I try to without closing and reopening it I get all kinds of errors.

So, in the mean time, I have just put a shortcut on my desktop that allows me to enable and disable the Local Area Connection when I need internet access.

A couple days ago, my boss's PC grabbed a virus that slipped past McAfee (that program is now gone!!) and really hosed up his PC. He bought the Windows 7 upgrade software and wiped the hard drive and installed Windows 7. He is now having the same issue as I am.

For what it's worth, he is using a Belkin Wireless-G USB wireless adapter, and mine is a Netgear Wireless-N USB adapter.

Is there any way we can have the two connections operate at the same time like they did in XP? It really becomes a pain sometimes when we are on the phone with a client and we need to jump back and forth between info that is online, and info that is on our server that we access through ACT!.

How To Share Internet Using WiFi Modem

Feb 3, 2011

I have a question about sharing my Internet. Ok my internet provider sends me some analogue signals, my modems gets them, converts them to digital signals and then, sends this Connection to where it should go (I mean I can use this connection using e.g. wifi). I have a vpn connection. I wanna use it on my mobile. My mobile doesn't support vpn configuration. So somehow I should send the vpn connection from my pc and modem. How can I share the internet I am using in my pc using my WiFi modem?

No Internet Access After Resetting Modem?

Nov 25, 2011

In order to change my password a service provider had to reset my modem.I can go on the internet with my desktop, but I am having difficulties going on the internet with my laptop. It seems that my wireless router has to be reset also but he can't do it because it's not one of theirs. He did explain to me though that I have to put the I.P. address into the browser in order to get on the router's brand name and so on, which I did but I don't know what to do next. My router's I.P. address is 192.168.0.1 It is a NEXXT Nebula 150?

Laptop Will Not Install Internet Modem Or Printer

May 31, 2011

I have an Acer Aspire 5740G and for some reason it hasn't allowed me to install my new wireless internet usb stick. I have an older usb stick already installed that I use, but it won't let me install this new one which works fine on my PC.

When I plug in the usb stick it makes that beep beep noise to indicate it detects the device but when I go into my computer the device pops up and then suddenly disappears.

I have my new HP eprint printer installed on my PC however when I plug the usb cable into my laptop after installing the CD it won't connect. This is during the setup when it says "connect usb cable" or whatever - but NOTHING HAPPENS!

Can't Remove Internet Modem USB Stick In Windows 7?

Aug 3, 2011

I am using Internet Modem USB Stick with my computer. My computer is Windows 7 Professional. I have a problem with removing the Internet Modem USB Stick from the computer. When I insert the Internet Modem USB Stick into my computer and then I wish to remove it, I really can't do so. I, however, can remove the Internet Modem USB Stick from the computer easily in Windows XP.I think it will reduce my Internet Modem USB Stick Lifetime and there probably should effect my computer lifetime if I try to remove the USB Stick without allowing to reject.

my newly built pc only connects to the internet when directly connected to the modem. when connected to the Linksys WRT54G, the internet does not work and there are no status lights on the ethernet port on my computer. however all other computers and devices, wired and wireless, all work with the router. my new computer is the only one that doesnt work with the router.

4. DNS and DHCP are enabled

Unable To Connect To Modem/internet Via Lan But Wireless Works Fine

Dec 4, 2012

My desktop (windows 7 ultimate 64bit) has been able to connect fine to the internet until I got home from work this morning. My laptop is connecting to the same modem fine through wireless (along with my wii). The modem I am using is Motorola SB 901. When I rightclick my connection on my desktop and hit troubleshoot problems, I get 'local area connection 2 doesn't have a valid ip configuration'. Same thing happens when I switch the ethernet cord to local area connection 1. When I go to control panel, network and internet, network and sharing, the connection map at the top stops between my pc and the network (which is now labeled as 'unidentified network'). Here is a list of what I have done so far to try and resolve the issue:

1. Replaced the ethernet cord with one I know is working

2. Full scanned my pc for viruses

3. Disabled all firewalls and virus protection programs

4. Restored my pc to a previous save state

5. Reset winsock with cmd via these prompts: netsh winsock reset catalog and netsh int ip reset reset.log hit

6. This attempt is unfinished as I am getting stuck. I am attempting to setup a static ip to attempt to resolve the issue, but when I open cmd and type ipconfig/all, the default gateway under my local area connection is completely blank.Here is what comes up with ipconfig/all:

C:UsersPaul>ipconfig/all
Windows IP Configuration
Host Name . . . . . . . . . . . . : Paul-PC
Primary Dns Suffix . . . . . . . :

Sharing Wifi Internet Via Ethernet

Dec 20, 2009

I've got two computers in my room: a Toshiba laptop and a desktop computer (both running Windows 7) I built a few months ago. The laptop gets great wifi reception, 4/5 bars, while the desktop struggles to get one bar. I want to connect the laptop to the PC via Ethernet and use the laptop's Internet connection. I'm having troubles doing this.

Here's what I've done thus far:Disabled the desktops wifi. Enabled "Allow other network users to connect through this computer's Internet connection" on the laptop's Ethernet card. Plugged in the cable.

This is where I hit the brick wall. On both computers, it comes up as "unidentified network". I try creating a homegroup on the desktop, but I encounter an error "Windows could not set the network settings" and "You can try to change this setting later in the Network and Sharing Center." I look in the Network and Sharing Center, and it says "Homegroup: Joined" as if no error occurred at all. So I try to join the homegroup on the laptop. It says "Larry from LARRY-PC has created a homegroup" so it recognizes it, but then it says "Windows could not setup a homegroup on this computer" when I try to put in the password.

I start the HomeGroup Troubleshooter, and it troubleshoots network problems. After that, it says "Local Area Connection" doesn't have a valid IP configuration: Fixed" So then I try joining it again, and get the same issue. I go through the HomeGroup Troubleshooter again, and I click "the problem is not fixed" and get a list of problems I don't have.

What can I do?

Cannot Connect To Internet By Ethernet Cable Or Wirelessly

Jul 12, 2011

My girlfriends parents have bought a new compaq laptop with windows 7. Connected up to the internet by cable & wireless no problem. Yesterday couldn't do either and found it nearly impossible to get into the routers settings to check them. Kept saying limited access. I've tried various things to no avail. Then I noticed that my iphone could connect to the router, so I ruled out a router problem. I brought the laptop home and it wouldn't connect to our router, so I'm presuming it's a settings problem. But now I'm stuck!

LAN No Internet Access When Connecting To PS3 With Ethernet Cable

Jul 19, 2012

I'm a 3g dongle to connect to the net, I previously set up the ps3 to connect through same via the wired connection. That work fine for a bit, until I updated the firmware, Since then the PS can't seem to obtain an IP address and after setting a static IP it gives me a DNS error. On the flip side, my LAN is giving me a no internet access problem(ipv4) and also an unidentified network

I've changed the cable, released and renewed and reset the ipconfig and also flush DNS. I'm having the same problem with my laptop. Both were able to share the connection with the PS3 before.

Using Computer's Ethernet Internet To Send Out Wifi

Jan 23, 2013

The university I attend doesn't allow modems and routers, but me and my roommates desperately need wifi for our devices, otherwise they are being wasted sitting around. today I set up an ad hoc connection on my roommates laptop, but he brings his laptop places and when he's out, we have no wifi. I have my desktop computer, and I can leave it on all the time and I never leave with it, so I'd love to set up wifi on it, since it will be so much more convenient.I brought my router from home, and ive gotten it to send out my computer's internet connection, but it brings me to the school's registration page, which I can not use, since routers are not allowed. Is there a way to use my desktop's ethernet connection and send out that internet connection through my router (it also needs to bypass the school network, somehow fooling it that my router is my computer (im guessing))?

Set Up A Dual Ethernet Card Internet Sharing With HT Receiver?

Nov 27, 2011

When building my Hifi mancave, I was smart enough to wire it for Cat6, etc, but not smart enough to put a few lines of cat 6 into my HTPC jack. So I only have 1 cat6 line into my computer area. My new receiver (Onkyo TX-NR809) has a ethernet port in it, which enables internet radio, media sharing, playing, firmware updating, etc. Being a techy guy I got another netcard and put it in my computer and I want to share internet to the receiver via LAN2.

I've been scouring the internet trying to figure out how to do this with Windows 7x64 to whatever system (probably linux based?). I've seen how to do it with Windows 7&XP, XP&XP, Windows 7&7 linux & Windows, and they all use some sort of "brige internet connection" or something like that, which doesn't apply to my situation. Will someone just tell me what IP stuffs to use for the following:

'No Internet Access' IP Address Shows Router Not The Modem IP Address

Jul 7, 2012

My internet connection shows 'no internet access' even though my ISP shows the connection is coming into the house just fine. I usually use a router (NetGear-WNR3500U) but I right now I have the Ethernet connection plugged directly into my PC. I tried directly plugging into my laptop and the internet works just fine. So I know the problem resides in the PC.

Some troubleshooting things I have tried.

-Power cycled my modem, router and PC.

-Repinged my connection from my ISP(Comcast Xfinity)

-Used the reset option on the router and the modem

-I was walked through the internet options needed with the tech support from my ISP to make sure DHCP was enabled and every other setting was correct, and he cleared me that all settings were correct.

-Tried ipconfig commands to /renew and /release my IP When I tried ipconfig /renew I get the error 'An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server'

-Restored my PC to a restore point where the Internet was working

All of these options did not work.

What I think the problem is and I am not sure how to fix it, when I run the ipconfig /all command my Auto configuration IPv4 Address shows 169.254.112.76 which I was told is a router IP address even though I am plugged directly from the modem to my PC with an Ethernet cord. So I think that's my problem? But I am not sure.

Internet Time Failing - DNS Resolution Error

May 15, 2011

My internet time is failing with the following error:

"NtpClient was unable to set a manual peer to use as a time source because of DNS resolution error on ''.
NtpClient will try again in 3473457 minutes and double the reattempt interval thereafter. The error was: The requested name is valid, but no data of the requested type was found. (0x80072AFC)

I assume either my ISP/router is the issue or something else strange is going on. I tried changing my DNS server to the google ones as well as adding a server to my hosts file but it still returns the same error. Just curious what exactly the message means if it really is DNS related as hard-coding the IP into the internet time requester returns the same error.
