Cabling / Cards :: Using 3 NICs In A Proxy Server?
Jun 7, 2011
I am using a proxy server with 2 NICs for sharing internet connection to my 100 desktop users in my office. NIC 1 is connected to my dsl modem and NIC 2 is connected to a main switch and further to more. But now i want to setup a wifi network for laptop users. I have enabled ICS on NIC 1 and NIC 2 has acquired it ip automatically (192.168.0.1) so the gateway for my desktop users is (192.168.0.1). But i want to use a new gateway. For this i have installed NIC 3 but it is not acquiring the ip automatically. My Proxy server configuration is: MS Server 2003 ENT edition.

I can connect directly to the router wirelessly without any problems. When I use my powerline adapter I get the 'unable to contact DHCP Server' error. I've tried unencrypting the router with no success. I've also released/ renewed my IP. [code]

I'm planning to create a network of wifi access points all in different locations. Those locations all have different wifi routers and networks. I'm looking for a easy solution that let easily setup those networks to ask authentication credentials (in a browser page, once a user is inside the wifi and wants access the internet) by an external server possibly without overloading too much that server.

So i have a server with an internet nic and lan nic. The internet nic gets its IP from the router 192.168.1.7 the lan nic uses DHCP for the network and has 172.16.1.1. I just turned on the ftp service and it works fine in the lan side but cant reach it from the ISP side. I use a dynamic dns host which is monitoring my internet ip and is correct.

My Internet is down. I appear to be getting power from the modem as all the lights are lit up. I have a wireless router. On my desktop I clicked on the Network icon and it said "3WIRE***" is in range but requires a Network Key (also called a WEP Key or WPA Key)? Could this be the problem? I've never had to enter a password to access my internet before. Do you know how I can find (or reset) my password? It's a D-Link router.

The situation is I have a windows 2008 server with two nics, connected to two routers. The routers are connected together as well. This diagram might explain further:[url]....
Each router effectively defines a completely different network. The server nic connected to the internet facing router is configured with minimal properties (no ip6, no file sharing, no netBIOS over tcp etc), the nic connected to the internal router has mostly default properties. Both nics have static ip addresses. Both networks define a subnet of 255.255.255.0. The nics are not bridged in the server and it is not acting as a router or anything network related.
The problem is I cannot access the server when both nics are enabled. If I disable the nic for the internet facing router, then everything is fine. If I establish a connection to the server such as through remote desktop, then re-enable the nic it still works but I can't ping or make new connections.

I have network: 20 PC's conected to a switch (ordinary switch), from switch to a router (for DHCP and internet conection), Router is connected to a cable modem.
Lately an issue arised. One PC started having problem witch connection (PC is windows 7, up to date). PC instead of 192 addres is getting 169 (i need to highlight it is a problem with only one PC). That means the PC is connected to the Router but it is not getting proper IP addres. After changig the addres to static the connection ws fine for few days and then in networc connection icon (botom right) it came up with 'unidentified network' message. I changed the patchleeds, even changed the connection with known working line (from outlet to patchpanel) and the connection was coming and going. Then I changed network card with the same resoult. I noticed strange thing: While the IP is 169 or when 'unid net' when I unplug the cable from outlet then plug back and do so couple times in one moment the connection is back and stable but only for some period of time. Cables had been re terminated with new jacks and at the patch panel. Drivers for network card are up to date.
Why is the connection coming and going?

I'm currently volunteering at a children's group near me. They've just moved offices and are wanting a computer network in place. I have quite a bit of experience with hardware and software troubleshooting, but anything past the server is beyond me.They have a telecommunications box, as many places do, and the box has a set of patch boxes that are, according to the telecommunications people, plugged in and good to go. Each office has tunnelling on the wall with network sockets, again the norm.

I have found a great application that allows your PC to become a hotspot. It can also protect the wi-fi. Now remember whatever its your backend on the PC is what kind of network and speed you get such as, if my desktop connected through ethernet and I install the virtual router on the desktop than my laptop can connect to it depending on my Wi-Fi adapter on it. It could be B/G/N. B and G gives 54MBPS and N gives me 65MBPS.

A few weeks ago, i noticed that my desktop was unable to access the internet, even though it shows that it is connected. i eventually decided taht it must have been a hardware issue, so i bought a new motherboard. after installing the motherboard, an a fresh installation on Windows, i saw after the drivers were installed that the same thing was happening. I pinged sites, and i got no losses on data. i also did a tracer, and it showed me that it is in fact connecting.
I noticed that when I connect the pc to the network(it is always via cable) it recognizes the network as "network", whereas if i use the same connection for my laptop, it brings up the network as "NETGEAR", which is, in fact, my network's name.

I keep getting a 50% loss on one workstation. I tried switching out the network card and that seems to have resolved the issue... Do network cards exhibit strange behavior when they fail or am I overlooking a deeper issue?

Having real problems setting up a USB NAS driver adapter. I bought this adapter here: USB NAS Adapter for HDD Caddy UPNP Printer Server SAMBA | eBay
I have plugged it into my router via the ethernet cable provided, then I login to my router via [url]... and check for the attached devices - I can't see the USB adapter showing up. My router is: F@ST2504n. Is there something I need to do first to make it show up?

I can open files, play videos, run programs, etc. Windows installed without a problem.However, I can't connect to the Internet. At all. I can't even register my version of Windows because I can't contact Microsoft for verification, because the connection won't get through. No Internet devices can be detected.That was with a long cable wired directly to our router, which is next to our modem.So, today, I bought a D-Link Xtreme N Desktop PCI adapter to connect. Still no connection... I don't think the PC even detects the adapter, because the drivers coming with the adapter can't detect it, and the light on the adapter doesn't turn on.That shouldn't happen. Both the cable and adapter go directly into the motherboard. My operating system is Windows 7 Ultimate 64-Bit, and my motherboard is an Asus P8Z68-V PRO.My ISP is Cogeco. All other computers and wireless devices in the house work perfectly fine.

I might fancy having my desktop stay in a sleep state, waking whenever I need to access it for a file or something, so I tried to use WOL. The nic and bios support it, however when I enable it...
The machine only stays off off for 5-10 seconds at a time. I think this is because instead of waking from only a magic packet, it is waking from ANY packet.

Driver software is from 2009 and it says there are no updates found,. RALINK TECH. CORP is the manufacturer and microsoft is the driver supplier, although neither website has anything for my piece of equipment (i have installed updates from both of them and my driver software is the same as before). How do I find updates for these drivers? When I search online all I get is driver update programs that cost money to use.

We're planning to install 24 strand singlemode fiber optic cable in three ocations. What is the best way to run the cables between the 3 locations. Location 1 is in the south, 2 is in the middle and 3 is in the north pretty much in a straight line.Should we run one fiber optic cable from location 1 to location 2 and another fiber optic cable from location 1 to location 3 or is there a better way? Maybe we can run from 1 to 2, 2 to 3 so that location 2 acts like a hub.Is there a way to just run one fiber optic cable from location 1 to 3 and along the way somehow splice that cable to go to location 2
