    Question Static IP Router Keeps disconnecting & reconnecting internet connection.

    One other possibility is that a device on the ISP network is trying to use the same IP address as your router. For example, if your ISP gave you five iP's - something like .101, .102, .103, .104 and .105. For the sake of example, if you choose .105 for your DLink router. Some other...

    Question What is a Proxy Server and how do they protect the computer network?

    this happens to be my area of expertise, so I'll jump in.. There are two main flavors of proxies: Personal use proxies that are intended to "hide" your identity on the Internet. These are used by individuals on the Internet who are doing something that they don't want easily traceable...

    Question Unable to connect to Local Network after moving the PC in a Enterprise building

    It is likely that the other part of the building is on a different subnet. That means the IP address assigned at the old location won't work there. You said you tried to adjust the computer use to obtain an IP automatically which didn't work. That is likely because the new location...

    Discussion Stuck at a job. Don't see a way out.

    This is a really old thread, but I can certainly empathize and think I can give you some ideas. Tech support jobs can be a slog, but it's all in how approach it. Do the best job you can, but use it to learn what is interesting to you and where you want to focus. In support, it's all...

    Question What must I do to make my LAN a 10GbE?

    Unless you need 10G, don't go there - The gear is expensive and most motherboards require new PCI cards, etc. If you do want to go beyond 1G, there is a lesser-known 2.5G Ethernet spec that is more common in consumer gear than 10G. For example, my Asus motherboard supports 2.5G, as does...

    Question Providing Wifi internet for remote areas for many users (>300).

    With that many users and the need for outdoor services, you probably can't use the average home router setup. Ubiquity has some very nice products that have a very nice set of gear that would probably work for what you need. Their gear will work with multiple WAN connections (like...

    Question How can I find DNS servers in a request?

    The simple answer - When you make a connection to a remote site, your computer only does a DNS lookup ONE time. That single DNS lookup returns the IP address of the host you are connecting to. From there, your computer sends a request across the Internet, going through a number of hops on the...

    Question How can we best protect our computer network using proxy servers?

    This just happens to be my area of expertise, so I'll chime in using an account from long, long ago. Proxies, in essence, provide you a way to filter outbound Internet traffic. Most companies use them from using types of content they don't want their users to get to - Things that violate...

    Server room auxiliary cooling

    That's some cool stuff, but it's designed to transfer heat from the servers to the environment. What the OP is worried about is ambient heat in the room that needs to be dealt with. The heat produced by a piece of gear is simply a function of how much power goes into it - More power used...

    OK, step back a bit.. Saying you want to setup a WAN is like saying you want to buy a new vehicle. It's all about requirements. Do you need a tricycle, a honda, a Ferrari or a semi truck? You have a lot to think about. You need to rate and prioritize your need for performance...

    restricting websites.

    If your Windows AD server is also the DNS server used by your clients you can put in some bogus IP's for the sites you want into DNS - i.e., www.playboy.com resolves to 127.0.0.1. The savvy people could get around it, but most would just give up. - G

    SSL VPN with no Static IP

    Does your SSL VPN product run on the same device that gets the dynamic IP from your ISP or does it run behind your router/firewall? If it's behind your router/firewall and you just port forward in it shouldn't matter what the external IP is. As long as it can connect in (dynamic DNS would...

    Remote controlling client behind proxy

    Most proxy servers are designed to protect internal clients from the Big Bad Internet (tm). They also help increase performance through caching and add a bunch of other cool things. There are several things to keep in mind about proxies. Most proxies are HTTP / HTTPS only (save those...

    Got a new 300gig sas server on raid 1. What sthe best external backup? tape?online?

    A good backup strategy should include a full server backup at least weekly and typically involves incremental or differential backups daily. (I usually like differentials, myself. Safer) To make life easy on yourself it's best to minimize tape swapping. I always like to aim for one...

    WiFi Network Adapters - PCI or USB?

    USB all the way, baby.. It lets you move the adapter around to the spot where you get the best signal, they are cheaper, more portable, etc. IMHO, PCI is not a good way to do wireless - You're sticking your wireless card INSIDE (and the antenna right out side of) a metal case filled...

    Question about improving range and reception on a wireless router.

    Several choices: 1: Get different wireless networking gear that has better range like some of the MIMO gear out nowadays. There's plenty of it on the market and it helps quite a bit. 2: Look at external antennas for your router - A directional antenna can help reception quite a bit...

    Cry for help with linux and cisco 350 cards

    Have you tried to just replace the .o files? It's certainly worth a shot - I believe they are loaded at boot and the new versions should load. If all else fails, try and use insmod to load them after boot and see if they find anything. If there's a makefile in the new driver disk, did you...

    Any Difference Between running....

    The big question here is what kind of service? If you're using a cable modem, the entire cable segment shares the same bandwdith. Two cable modems in the same house won't have ANY positive effective on bandwidth available. DSL, however, is NOT a shared technology - You get your whole...

    Metro Optical Ethernet troubles, please help - FIXED!

    Do you have root on these boxes to take a tcpdump or a snoop? That might be the most useful thing to show what's actually happening at the network layer. Try and snoop one of those tests and save it as a .cap file and pull it up in Ethereal. There's a way to build a filter to colorize TCP...

    I need to build a server rack.

    There's two different things you can use to hold servers. You can use a traditional two-post rack or a you can use a cabinet. Most servers nowadays are really not designed to be mounted in a two post rack. Those are really best used for network gear or things that work well on shelves...

    Hey cool. An interesting question here! Looking at your diagram, I assume that this is ALL Layer 2 and that there isn't any layer 3 switching or routing going on here - You've just extended the segment between the two LANs. One thing that doesn't make sense is that you've got your 7200's...

    TCP flag: RST

    It sounds like you're trying to use Active FTP, where there is a new TCP connection established to deliver the file. Try to find a way to sent your FTP client to passive mode, where the same TCP connection that controls the session is used to transfer data. It's a lot cleaner and better...

    Turn router into WAP

    The Internet IP should be something totally random and made-up. 100.100.100.100 or something. Your LAN IP should be a real address on your local network. If your Internet IP is the same as your LAN IP then the router is probably trying to send management traffic out of the Internet port...

    USB Wireless NICs

    In general, better. Wireless is all about signal strength and antenna positioning. The WORST place you can have a wireless card is behind a bug chunk of metal and interference - Your PC. Your best bet is to get a USB wireless card and a USB extention cable. You can then move the card...

    D-Link DIR-625/635. No WEP?
