Router help

By alyssaogilvie ·
I am a student living on residence at University. Last week, i tripped over the cord that connects me to the internet. I can see that I bent 2 pins and so my internet will not work. I brought it in to computer services and I need a new motherboard. Looking for a cheaper option, I went out and bought a wireless router. When installing it, found there is something in the system blocking my router. I am not at all tech savy when it comes to computers so hopefully there is an easy way to get around this.
Thanks so much in advance for your help.

Using a wireless router...

by finsfree In reply to Router help

Hello I would love to help you out. First things first, when using a wireless router you must connect it using a wiress NIC. This is the correct way for using wireless. Meaning you should buy a wireless NIC and install it in your PC into a slot called a PCI. This is better than using something like D-link that uses a USB. After installing the wireless NIC(drivers included) your PC will let you know of the wireless signals available in the area. You will see this in the bottom right of the desktop. Then connect to the one that yours and BLAMMO.

Using a wireless router on school network

hey finsfree

Thanks for the quick reply. The problem I am experiencing lies in my School disallowing routers. I am wondering if there is any relatively simple way to get around this... I already have the NIC and router, but my connection is being barred by the various university restrictions....

Laptop or desktop?

by robo_dev In reply to Router help

Is this your own computer or does it belong to the school?

What make/model of PC do you have?

What kind of wireless router did you buy?

When you say 'something blocking', do you mean that you hooked everything up and it cannot communicate?

Or do you mean that something won't fit in a certain slot or port?

If this is a laptop, and you damaged the ethernet port, the best cure would be to buy a USB ethernet adapter for around $30. This would give you a replacement ethernet port that would plug right in very easily.

Using a wireless router on school network

by alyssaogilvie In reply to Laptop or desktop?

This is my own Dell Inspiron Notebook. I bought a D-Link router. My school purposefully blocks routers, I am trying to figure out a way to beat this system. I have everything and I think it would work off campus, this campus is just not allowing me to use the wireless.

I bought a PCMCIA network card to get around my damaged usb port... but it was not compatible with Vista... really annoying...

USB or RJ-45

by for_merlin In reply to Using a wireless router o ...


Are you using an RJ-45 ethernet connection or a USB connection to connect to the campus system?
The RJ-45 is larger than the typical telephone wall outlet. It has a plastic catch (tab) that anchors the connectors together. A USB connector does not have the tab or plastic catch.
I do not know who you took your laptop to, but female RJ-45 connectors are industry standard, and unless DELL had some custom manufactured, you should be able to get a replacement at any electronic hobbyist store. Most computer repair shops are reluctant to repair notebooks, simply because they do not have the necessary parts. And because they are much more difficult to dis-assemble and re-assemble.
In this case, it is necessary do dis-assemble the notebook until it is possible to remove the motherboard. Then remove and replace RJ-45 connector. Before I did this or anything else, I would attempt to repair the existing RJ-45 connector.
FIRST remove ALL of the batteries and any external power source from the notebook. A very bright lamp, a 10X magnifying glass and a hobbyist's Exacto knife set will allow you to look inside the connector and determine what pins are bent. A very sharp blade on the knife will allow you to straighten any bent pins. And, if you break one off, you have not lost anything, the PC will still work.
If you are unsuccessful or do not wish to attempt this, the second thing I would do is locate a PCMCIA (PCI) card with an ethernet port on it that is Vista compatible. I am surprised that the one you purchased is not Vista compatible.
Did you use (access) Device Manager in Vista to disable the on-board lan connection and turn off the on-board lan connection in the notebook's BIOS before you attempted to add the new PCMCIA card? If not this may be why Vista is not compatible with this card.
I am not really familiar with Vista, But, Windows in general (at least all of the non-server versions I am familiar with Windows 2.0 through XP Pro) does not like second LAN devices period.
The server versions of windows were designed to support more than one LAN device, the desktop versions (IMHO) really were not. Depending on the network card it may be necessary to modify the registry to get a second device to operate properly.
What I am saying is that I would try to comply with the school's policies before I added a router. Not because it cannot be done, but because you will learn a lot more about routers and wireless connections than you really want to know.
The MAC (Media Access Control) ID system was designed as a means of identifying EACH INDIVIDUAL device that attempted to access ANY type of network. It was meant to be unique to the individual piece of hardware used to access the network. Every network interface device manufactured or sold in the United States, and most other countries, since before the turn of the century has been required to have a unique (MAC) address.
I am pretty sure that the school is using MAC address assignment as well as ethernet port assignment to grant you access into their system. That is how most networks are configured. The school's router, server, or hub will assign a unique address to each ethernet physical port inside each individual network. You cannot change this ethernet port address assignment. It is configured in the school's physical equipment (router, server, or hub) that, you access (use). This is true wherever you are on or off campus.

That said, if you really want to install a router with school access, you should use a computer with a working ethernet connection to configure your router. And a real computer "geek" for a couple of days to help you configure the router. It is possible to configure a wireless router using the wireless interface, but this is NOT a secure process, particularly on a college campus.
What you will probably have to do is make your router look EXACTLY like your notebook. This is not a trivial task, and you may loose some (say most) of the benefits of a router (the ability to connect more than one computer to the school's network using a single network address, a restricted hardware firewall with port blocking, etc.). You can change "spoof" the MAC address of most of the D-Link routers to duplicate "clone" ONE MAC address. Your D-link router will show you the MAC address of the device you are using to connect to it on the "clone" page. Then you will need to open all of the ports in the router that are open on your notebook. Why? Because you want to make your router look EXACTLY like your notebook with just one wired MAC address. You may need to turn off dhcp services from the router because this is where a second or third computer would get a address from the router. It is probable that the school will use s a static IP address for your local port (the ethernet connector on the wall of your room). You will have to determine what this address is.
Then in the end after you have worked on this for far more time than it is worth, you will learn that the school performs traffic analysis on a routine basis. Traffic analysis is usually run in the background of most servers. The school does this to make sure they provide sufficient bandwidth to all of their users. Routine traffic analysis on the school's network will show traffic flow from and to more than one computer to your ethernet port and MAC address. And then the school's network services department will at a mimimum restrict your bandwidth, and report you. If I were the network administrator I would have to (that is their job.) If you open the Status page on your D-link router and look at STATS or LOG you will see a small part of what a good network traffic analysis program can provide.

Good luck and happy networking.
