the campus computer in my office won't connect the the Internet/NCSU network through my wireless router. Any way to fix this? Do I just need an Ethernet switch?

If so, any good deals/inexpensive ones/have any I can use?

i'm confused by what you're asking.

The ncsu computer in my office (on campus) will not connect to the Internet/ncsu network through my wireless router - it will when hardwired into the ethernet port on the wall. I use the wireless router for my and my officemates' laptops so I need to keep the router, but I also need the ncsu computer connected to the internet.

How can I get this computer to connect? I figured an ethernet switch would work, but I didn't know if there were other options.

Without knowing which router you have... I'll still suggest this because it works on most Linksys routers. Connect NCSU's connection to port 1 of your router. Then connect subsequent devices on down the line. The router then acts like a switch, and you can get an NCSU IP address, rather than one from the router.

I assume you're somewhere that doesn't have wireless access?

The right answer is to call ComTech and tell them what you want to do. Be warned that it may cost you money.

NCSU does NOT like 3rd party supplied routers, esp wireless, or AP's to be placed on their network without approval. Esp as the NAT function means that folks with no LEGIT reason to be on the ncsu connection can then leach from it.

2/15/2009 10:20:37 AM

^^^that = no wireless then
^^there is wireless but very unstable. I'm not paying the University for an Internet connection when it's supposed to be free.
^I'm fairly certain that non-legit people aren't leaching. the signal doesn't reach very far (cinder brick walls ftw/ftl), so it's contained to within a few offices (thus no areas to sit and use a computer - unless you're sitting in the hallway), not broadcasting, network key, & mac filtering.

Our laptops work fine off my router, it's just that the ncsu computer won't.

DI-624 (i think that's the right model)

and then have them remove my router, sure.

First try putting the NCSU computer in the router's DMZ.

If that doesn't work, clone the NCSU computer's MAC address to the router.

You're right. Why would you want to talk to the actual people who can tell you how to solve your problem easily when you could just hope someone on TWW will tell you the right answer?

on resnet connections they don't care as long as you're not inadvertently poisoning DHCP requests
on building networks, comtech will make your life miserable if you get caught.

the right thing to do is call comtech and get your department to buy an AP to put on nomad if you really have a need for wireless access.

(i used to work for ncsu ITD)

2/15/2009 2:34:14 PM

because ncsu wireless is so secure

2/15/2009 2:48:16 PM

shhh.

2/15/2009 2:49:13 PM

^^

at least then it's comtech's responsibility, not yours.

2/15/2009 3:40:48 PM

thanks for the responses. I'm just going to go hardwired for everything to avoid complications.

2/15/2009 6:30:46 PM

if its a campus owned computer, call comtech, they have mac address locks on everything. thats probably also why your router wont work.

Resnet is totally different. if you are basing off of being in the dorms, resnet != rest of campus including nomad, which what he is on isnt nomad either.

like comtech cares about the security of your datas

if they did, they would at least have a shared WPA2 key

it's not really a mac address "lock" per se

you just can't get a DHCP lease unless your MAC is in QIP

2/15/2009 11:08:45 PM

KISS Evan. Yes point, but Im trying to not get into a 2 hr lecture on how exactly the network works.

2/16/2009 9:56:21 AM

that wasn't a 2 hour lecture, it was a 2 line statement.

2/16/2009 10:59:42 AM

look he reads slow ok

2/16/2009 11:01:37 AM

it's a pretty pointed two-line statement, as well. it implies that the OP can spoof the MAC of a listed PC on his wireless router it should work without issues

Quote :

"IV. Implementation of private wireless networks on campus A. Those who implement private wireless networks on campus are responsible for compliance with the rules, restrictions and provisions described in this document and for support of the private wireless network, including the network traffic. B. Those who implement private wireless networks may employ wireless encryption technology if desired. They should be aware, however, that current wireless encryption technologies are weak, and it remains possible to eavesdrop and to passively decrypt wireless networking traffic. C. Departments and authorized individuals may set up private wireless networks on campus as long as their installation does not interfere with the NC State public wireless network and the private wireless network is set up in compliance with the following standards: 1. Transmitter (access point or base station) registration All wireless networking transmitters MUST be registered in DNS with a descriptive name in the format of building-nearest room#-type-channel (e.g., "withers-410-proxim-6"). In most cases, registration will be done by the local LAN administrator. 2. Channel selection Wireless transmitters' channels must be configured so as not to disrupt any NC State public wireless networking transmitters or other private wireless networking transmitters. Contact ComTech for appropriate channel selection. Administrators of neighboring private wireless networks should also be consulted. 3. Access control All private wireless transmitters MUST be configured to allow only known client hardware to use the network. This is best done by setting the list of client Media Access Control (MAC) addresses that are allowed to use the private wireless network. Implementers of private wireless transmitters will be held responsible for the actions of those who access the campus network from those devices. 4. SSID (Service Set Identification) The SSID must not be set to "ncsu." SSID selection should be coordinated with administrators of neighboring private wireless networks. 5. Configuration password All transmitter configuration interfaces must be password protected with a non-default and hard-to-guess password. (See http://www.itsecurity.com/asktecs/jun301.htm, for examples.) 6. SNMP (Simple Network Management Protocol) SNMP strings should not be the default and should have access lists assigned where possible. 7. Power settings Private wireless transmitters should use the lowest possible power output that provides the needed coverage area. 8. FCC regulations All private wireless transmitter configurations must be within FCC regulations for dissipated power, etc. (Available from http://www.access.gpo.gov/nara/cfr/waisidx_01/47cfr15_01.html. Section 15.247 covers the amount of radiated power in the 2.4Ghz band.) 9. Fire codes All private wireless transmitters must be installed so they do not violate fire codes. Contact the NC State Senior Inspector of Fire Protection (515-2568) with questions. "

aka dump the router, grab a 10 dollar switch as well as an access point and then call comtech? I think most companies these days try to charge more for an access point than a wireless router, so they make disabling DHCP and doing what the 2nd or 3rd post says near impossible.

get a WRT54G and stick DD-WRT on there

you can then disable DHCP and just set it up as an AP/bridge.

probably the best idea in this particular situation.
