Finding a rogue WiFi router on local network

This is likely a very odd and possibly complicated question, but I figure I'd throw it out there anyways.
At my office, we have a couple wireless routers throughout the building. However, one in particular has started to act up. It used to work perfectly, but in the last month or so, it has stopped working. Connecting to it via the password that was set no longer works. Laptops can SEE the network in a list of wireless connections, but we can't log into anymore.
Now, normally a easy solution would be to find the physical router and reset it manually. But here's the problem.
We don't know where it actually is. It was installed before myself or the current IT specialist were hired. We were able to use a Macbook and iStumbler to detect its general location by walking around the building and guaging signal strength. But we still can't find it. It's likely up in the ceiling somewhere. Don't ask me why.
So, I'm wondering if there's a way, be it through an app, Terminal, etc, to detect the router over the network. If we're able to get the IP of the device, maybe we can log into it and possibly fix the problem.
If not, perhaps people know of a good device we could purchase to further locate the physical device it self? I've seen a handful of WiFi detectors, but they usually only show 1-5 bars - nothing more.
Any insight?

I assume you mean that you have several wireless access points, not wireless routers.
Have your IT Dept disconnect the ethernet cable that connects the Access Point to the main switch or router, and then "tone" the wire to trace it.
Use one of these:

Another option is to flash the firwmare over the LAN, BUT that will probably default the Access Point to an address already in use and that may create a bigger problem.

Hi, I am looking for a printing solution for iPads in the office space, my question is how can I print from iPads and if the iPads are connected to a wifi router on a network would I be able to print from a networked printer?

Hi
We are looking at placing iPads in our offices but need to understand the printing options available? I have a number of questions?
1/ Would I be able to print to a networked printer?
2/ what would be the best WIFI Printer available for extensive printing?
3/ Are there any other printing options available?
Thank you in advance!

The roll over logs all have the same name exact the extension is .lo_ , So.. I'm not sure what you are looking for.

AirPort Extreme 802.11n as a wireless router and local network switch?

Good afternoon,
I'm curious if its possible to have the APE in wireless network mode and connect systems via hard line as well?
I have an AirPort Extreme 802.11n set to "Create a Wireless Network" mode that is attached directly to a cable modem for internet connectevity. My issue is that while all wireless devices (several iPods, two iPhones and three laptop computers) connect to the APE without issue (and have internet access), when I try to plug in a Windows 7 desktop computer via one of the ethernet jacks, Windows is unable to connect and shows the network as "unidentified," spitting back a private IP address as opposed to a local LAN (this behavior repeats for an Ubuntu Linux box as well).
Not sure if the APE is misconfigured, this is a Windows 7 issue or if its improper use on my part (though this also precludes me from connecting a gigabit switch to the APE).
Thank you,
Nathan

Properly configured, the AirPort should provide both wired and wireless network client with Internet access.
At this point, I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

Apple TV internet no Airplay from IPAD despite WIFI router

Hi,
My Apple TV2 is connected to my Ethernet wired network, there is a Netgear Modem Router on this network that allows DHCP and WIFI access WPA2 secured.
The Apple TV can connect to the Mac to share the itune Library over wired ethernet.
My Ipad connect to the same Netgear throught Wifi and I can access every Mac on the ethernet network with all apps.
BUT No way to connect iPad Wifi to the wired ethernet connected Apple TV, I mean iPAD wifi to the netgear router to ethernet wire to the Apple TV, exactly what I do for mac's and pc's that are ethernet connected to the netgear Router.
My iPad can connect to MAC with the same network for screen sharing with decicated Apps.
If I unplug the apple TV from Ethernet wire and I configure WIFI, my Ipad connect instantly to the apple TV for Airplay or remote.
Wifi is far too slow for Video display, you have to wait a lot before it start and it jitters, so I need the fester connection of my 1GB ethernet network from Apple TV to MAC, this is working well but then I cannot use ipad airplay...
every Item is using DHCP from the netgear.
I hope this is clear enought.
Did anyone succeded in implementing such a network configuration???
Does Apple TV neeeeddss direct WIFI for using Aiplay from iPad (it's the same for iPhone by the way) ??? WHY (performance, bonjour, marketing lock ??)
Is there a way (by Jailbreak?) to enable ethernet wiring and Wifi on the Apple TV???
Tahnk you for your help
Regards
Luis

The netgear router did not work properly with apple TV, I disconnected its WIFI and use it only as a modem for internet cable to ethernet local network, so no wifi.
I bought a time capsule that I included in my ethernet local network and used its wifi as a bridge for wifi devices (ipad iphones) to local network with internet acces through the modem router.
Then I connected my apple tv2 to my ethernet local network.
With this configuration my ipad or iphone can through time capsule wifi access ethernet local network and use apple TV2 to display ipad/iphone screen/video on my TV. superb indeed...
regards

Scanning local Network

I tring to scan local Network!!!
How can we find all ips or hosts of local Network????
Thanks!:)
Best, Aram.

I have the same problem.
I use a mysql database together with my own written java program (huge).
Now I create a new client in my program, and i want to give him acces to the mysql database.
This isn't really hard, BUT:
When you create a user in mysql (with GRANT) you can use a host name. Because if you don't that user can acces the database from every pc within the local network. I don't want that to happen.
So when a new user will be created I would like to have a JComboBox with all the active Pc's that are on my local network.
Can it be made????
otherwise is there a windows command (in command line) that let you see all the pc's that are available in a local network???
Greetz,

Can I use wifi for internet, while ethernet only for local network?

Hello everyone. We have two internet connections at our office. One is wifi only -- but fastest uploads. The other is connected to our ethernet network (and very slow). Really, it's not much a network -- just iMacs connected to a switcher. When transferring files between iMacs, obviously we want to remain connected to ethernet. But when uploading and downloading files, the wifi option is quickest (long story why -- our offices next door, can't run a physical line yet, yadda yadda).
So we find ourselves constantly switching between the two in network preferences. Not only is this a pain, but it doesn't allow us to upload or download directly to a drive on the network.
Is there a way to tell the preferences to use wifi for internet, and ethernet for the local network (without internet)?
(We have updated mountain lion on i7 imacs, and most recent airport extreme)
Thanks!

Your downstairs router can be installed anywhere in your home, but telephone companies or ISPs are only obligated to install their equipment just barely inside its service entrance. Usually, that location is the worst possible one for a home network, since it's in a basement or some remote corner, far from all the devices that use it.
Your idea to install an Ethernet cable to extend its reach to a more suitable location is an excellent one and will be worth the effort or expense. If you don't want to do it yourself a qualified electrician can perform the work quickly and elegantly, and you may find the cost surprisingly affordable. Ask your friends and neighbors to recommend a reputable electrician and get a written estimate.

I installed a new wifi router and airport will not connect automatically to it. It sees the network but will not connect unless I tell it to.

I installed a new wifi router and airport will not connect automatically to it. It sees the network but will not connect unless I tell it to. I can't find anywhere in the utility or network preferences that will allow me to choose this router as the default. How do I fix this? BTW I'm using Lion.

Are there any previous networks that you have used that have the same password as Molly? YES
Using System Preferences > Network > AirPort Advanced again, you need to remove any listings of previous networks that used the same password as Molly. Click the name of the network and click the - (minus) button at the bottom of the list of connections.
Also delete any other networks (except Molly at the top of the list) that might have used the same name...Molly in the past.
Delete any other networks that you no longer need so that your Mac will search for networks more quickly
Click OK, then click Apply
Open KeyChain Access and look for a listing of any old networks that you no longer need. Click to highlight the name of the network, then click the Delete Key on your computer.
Then look for any old networks that might have used the name Molly in the past and do the same for them.
Then look for any old networks that might have used the same password as the password for your "new" Molly network and delete them in the same way
Click the KeyChain Access menu just next to the Apple icon in the upper left corner of the computer screen
and then click KeyChain First Aid
Enter the main administrator password for the Mac you are using and highlight the Repair button. Then click Start. You will see a message that repairs have been completed
Quit Keychain Access
Power down the entire network...all devices...order is not important
Power up the modem first, then your main router, the other devices one at a time
Log on to Molly and see if the Mac remembers it after a few tries. If not, I'm afraid that you will need to change the name of the wireless network and password on your router due to corruption issues on the Mac. You have done everything possible without re-installing the complete operating system.

I believe iMac is freezing because of interference between my Wifi/router combo unit and my Network Card. What should I do?

My mid-2010 iMac (Snow Leopard) has been freezing with a spinning wheel within 10 minutes of startup for about a week. I can only force it to shut down by holding the power button - nothing else functions at that point.
I've been to the Genius Bar 3 times, with no findings. They did an overnight diagnostic, and found nothing wrong. They reinstalled Mac OS X, and before I even restored, it was still misbehaving. I can't recreate it at the Apple Store, but it does it without fail at home. At length, I believe I've narrowed it down to the Wifi/router combo unit and the iMac network card. When I turn off the router (entirely or just "turn off" the wifi), it oeprates normally. If I turn off the ethernet (BOTH en 0 and en 1 - if either of them is on, I have problems), it operates normally. If I have them both on, it will freeze. What on earth?
It doesn't matter whether the iMac is actually CONNECTED by wifi or ethernet. Merely having them both TURNED ON is enough to cause the freezing. Has anyone heard of this? I can't seem to find anything on it. My only recourse seems to be asking my DSL provider for a new router and seeing if that helps.
Any other suggestions? Thanks!

I can't recreate it at the Apple Store, but it does it without fail at home.
That's because when troubleshooting no devices should be connected except for the keyboard.
You seem to have narrowed it down to your router. Suggest that you call the router manufacturer to find out what the problem is. If the router came from your ISP, call their tech support dept.

TS1398 I can't find my wifi name or signal or any other wifi spots and I'm right next to my wifi router box and my iPod isn't detecting my wifi router box I'm my house

I can't find my wifi name or signal or any other wifi spots and I'm right nepxt to my wifi router box and my iPod isn't detecting my wifi router box I'm my house

If not:
iOS: Wi-Fi or Bluetooth settings grayed out or dim
One user reported that placing the iPod in the freezer fixed the problem.
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.
Apple Retail Store - Genius Bar
Then
Does the iPod connect to/see other networks? (you were not clear)
Does the iPod see the network?
Any error messages?
Do other devices now connect?
Did the iPod connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

VPN Server with two router local network

I just got a Mac Mini Server 2011 to set up as a home server. One of the main features I want to use is a VPN so I can access my files on my local network when I'm away from home. I live in Japan and I have a Japanese optical connection to the internet that runs through two boxes before I can use it in any form: some sort of modem, and a "gateway" which I literally just found out is also acting as a router and serving DHCP addresses. In addition, I have a 2TB Time Capsule that, until just recently, I had been using in the "Share a Public IP" mode because I didn't realize the gateway was also issuing DHCP addresses. I cannot simply plug my TC into the modem in place of the gateway - both are required to access the internet.
Until today I had both routers using DHCP on the local networks they each created. Under that environment, I had finally configured Lion Server to file share (easy), manage network accounts (moderate), and serve Profile Manager (difficult). But despite my best efforts at mapping the ports on the Time Capsule, I just couldn't get the ports open using tools like canyouseeme.org, so the VPN was a no-go. That's when I realized the gateway could be a router too, so with some creative google searches, and extensive use of google translate, I was able to figure out how to open ports on the gateway. It does it pretty differently from the Time Capsule and other routers I've seen. It asks you define the host on the LAN (what i assume to be the target IP), the protocol (TCP vs. UDP), and then a range of ports for it to open. I plugged in the IP of the Time Capsule, opened all the UDP ports (since it was an option to just open all, and I figured 1) the TC would still protect my network and 2) it would just be a test), but I still couldn't see the ports as being open.
So then I got desperate, and I switched the TC back to Bridge Mode, reconfigured the Server and my MBP (my client Mac) to the new IP addresses being served by the Japanese gateway, and tried again. I think I reconfigured the DNS settings in Server Admin properly to account for the change in IP, and then updated the services in Server.app, but now I can't even get to my server homepage (the apple placeholder page) using either its IP or its .private domain, and to make matters worse, I STILL can't seem to get the ports open (yes, I changed the port mapping to send it directly to the server IP as the target after the change).
To add insult to injury, the wired ethernet connection I had been running from my TC to the MM Server is now reporting a cable unplugged (it's not), even when I plug it directly into the gateway, though I am able to connect wirelessly.
Does anyone have any idea what's going on? Why can't I get these ports open? (By the way, I called my ISP and they said they aren't blocking any of the ones I'd want to use for VPN.)
What is the *better* set up - using the TC as a second LAN, serving its own DHCP addresses, or using it in Bridge mode?
Why did these changes sever my wired connection?
I was getting even more problems (like loss of internet connectivity on all devices) using the TC in bridge mode, so I decided to go back to the dual network setup.

Hello Eric,
As I mentioned above.
For external Internet access, I would create a Generation
1 VM
and use 2 Legacy Network Adapters for
the Interfaces . Connect it to the External and Internal network, and then install VM Linux IPFire (How
to install) and
configure IPFire with RED and GREEN interface.
You don't need router or any firewall.
I have the same set-up that you are trying to do in your lab and it's working great.
All my VMs / computers on the LAN have their gateway the Linux VM.
Hope this help.

Can't find computers or drives on local network

I cannot find any networked computers or harddrives on my local network. I can connect to the internet through my timecapsule, but I cannot access it or any of the other computers (all macs) in the house, either wirelessly or wired. They do not show up under "Network" in finder nor can I ping them.
The other computers successfully find and mount each other, the timecapsule, and my computer.
I recently put in new ram; could this be the culprit?
How do I fix this??
Thank you very much!

upgraded to snow-leopard

My iphone 5 does not remember the password of my home network. Well this is ot the case with my ipad. The wifi gets disconnected every 2 minutes. Its not any problem with my wifi router as my ipad and other devices work fine. So how do i fix this problem?

Well my iphone 5 does not remember my home network. This is not a problem with the wifi router as the ipad works absolutely fine. The wifi loses it connection in just 2 minutes. So could you please fix this problem.

Not unless the modem is causing a problem.
What you want to do is get it to work reliably over Ethernet first, then tackle wifi. Power off the modem. On your macbook, delete the Ethernet configuration and the Wifi configuration. Power up the modem, then connect the mac via Ethernet. Create the new Ethernet configuration and see if you can connect.

When I try to sync my iPod iCal with my MBP iCal via WiFi I get a message saying "Safari Downloading Safe Browsing Data" but I am connected to a local network and thus the syncing does not complete"

When I try to sync my iPod iCal with my MBP (OS 10.7) iCal via iTunes and WiFi I get a message saying "Safari Downloading Safe Browsing Data" but I am connected to a local network and thus the syncing does not complete because the downloading never completes because I am not connected to the internet.
Why does syncing iCal need Safari Safe Browsing Data? How can I turn this off?

See:
iTunes 10.5 and later: Troubleshooting iTunes Wi-Fi Syncing
"Safari Downloading Safe Browsing Data" is just some data that is synce with the computer. To turn off on the Mac go to System Preferencs>iCloud and turn off Safari

MBP can't find one specific wifi network.

The hotel where I live offers free wifi (The Cloud) and for months I've been using with full signal.
Suddenly my MBP (mid 2010) was unable to find this network.
My iPad and my iPhone (and friend's devices) are still connecting at any time with perfect full signal.
I've tried holding alt+cmd+P+R at boot to reset PRAM and NVRAM but it still can't find that specif wifi network.

Update: after another NVRAM and PRAM reset (alt+cmd+P+R) the wifi network shows up but I'm still unable to connect to it. When selected I've got a message of "connection timeout occurred" and the network disappears again.
*All software is up to date.
