Wireless :: 3 Different Mac Addresses Displaying In Network
Mar 5, 2011
In my wireless table of who is connected to the wireless network there are 3 different mac addresses displaying when there is only two computers in the house(its not an outsider, it only shows when the other PC turns on), 2 of them have the same computer name but are connected at different IP addresses(192.168.1.101,192.168.1.102). Side Note:[The 2 PCs in the house were bought at the same time and the mac addresses are similar, but the third is different] Now that i have installed ubuntu i can really see what's going on with my ports, i notice that the mac address, that is not similar to my PC and the 'other pc', is poking around at my ports whenever the 'other PC' is turned on.

I lost my internet connection icon in windows 7. When connected, the network notification and icon appears at the taskbar and displays how many bar signal the network has and it was working even earlier this afternoon here. I just used my wired connection for a short time and as i stopped using it then i discovered the wireless connection bar signal is lost, all for me to see a ' Round Star' in the bar side of my internet icon. Am connected to the internet but i can't my connection signal and i tried to restore my computer but after i do that i get a dialog say 'The system restore did not completely succesfully because an anti-virus is running on this computer and has prevented it from changing the settings, turn off anti-virus ans try again' but i have no anti-virus program on my PC.

I've been having some problems with the Monitor Clients menu on a WCS 7.0 server, for instance if I go there and display the detected clients on the last 24 hours I get a different set of clients than if I go and generate a report of unique clients for the last day on the report menu. Is this normal?, shouldn't both reports get the data from the same place and give the same result?.

So whenever i plug in my computers with an ethernet cord to my router i get an older, different ssid name displayed in local area connections instead of the one being displayed on the wireless network. For one computer it displays the old ssid name 3011, with a 2 right next to it (i think thats because i had another router with the same name), i changed the ssid twice, but when i plug it into the computer it still displays 3011 2. The other computer displays the first newer ssid but not the official one listed on the wireless network. Either way neither of my computers display the name i have as the ssid when plugged into the router with a cord. do i need to do something else so the names match? i reset the router and updated the firmware before writing this, it didnt do anything. i have windows 7 business for both machines.

We are using LMS 4.0 with license of 100 Users. We are managing 12 devices till now. But from last two days I am trying to add a device ( i.e. 2811 router) and after adding the device in DCR (Inventry> Device Administration>Add/Import/ Manage Devices) it displays message i.e. devie added succesfully. But this added device is not displayed in Inventry> Device Administration>Add/Import/ Manage Devices.
observation :
1. In managed device list router 2811 is reflecting in Device Type Groups, but not in all devices.
2. New added device is reflecting in Known device list if we generate a report for know device ( under path Reports>Invenrty>Management Status>Known Device List).

In setup for old RV042 (V1), when updating / adding Mac addresses, the table is always sorted by IP addresses. But in the new oneRV042 (V3) I have, even with latest firmware 4.2.1.02 the list is random, thereby increasing the chance of user entering DUPLICATE IP addr with diff Mac addr. That will result in conflict.If the firmware sorts the DHCP entries by ip addresses, user would be able to catch duplicate ip errors even if the system does not flag the errors. All Cisco smart engineers can you all get the dhcp entries SORT by ip addresses.

I have a desktop and bought a wireless adapter to hook up to my apartment complex's wireless network through cox. We have had no connection issues for several weeks.Randomly, both IE and Firefox stopped displaying webpages. Firefox displays the message "The connection to the server was reset while the page was loading."Our apartment complex has tech support, so I called him and we went over so many things. The issue, as he says, is that when I do an ipconfig /release, I SHOULD be showing, under my wireless adapter, the ivp4 address as 0.0.0.0. When I do the release, it shows no ivp4 address, period. It shows I have, and am connected to, the internet and the connection. My apartment complex has 5 different wireless connections I can try, and all result in the same problem. I am able to ping google, yahoo, etc, but when I try to ping my apartment complex's wireless connection (their router) it fails.
Uninstalling and reinstalling the wireless adapter and software, system restore, reinstalling windows, restarting the WAN service under services.smc, unchecking ivp6 under my wireless adapter properties. I have tried disabling McAfee and Windows Firewall. I have no idea what else I can do.I also should note that I have 2 computers of the exact same model, and both present this same exact problem when I connect the wireless adapter to it, so it leads me to believe it is something to do either with the adapter or something with the connection from the adapter to the router. (I can connect to the wireless connection but not to the router itself to login to my complex's internet agreement page.)I have Windows 7 32-bit. I was in the process of signing up for Netflix when this happened, and did not download anything.

I have my device configured, and it has an IP, subnet, etc.I currently have it connected with serial port to my laptop and used PutTy to get into it,
However, despite it having an IP, I cannot use the web browser with it! This is driving me mad. I want to use the web browser and not the CLI for everything. it has a BVI1 IP as well as an Ethernet address.

Whenever I access a file through HTTP, it seems to require that I completely load the file before it will display.
1) For large images, this will result in the whole thing taking some time to load before displaying in its entirety, unlike the usual progressive rendering.
2) For file downloads, this will result in the file being downloaded only after being cached, appearing only when the whole file has finished downloading, unlike the usual process where it can be seen as a progress bar in the browser's download window (for some reason, FTP downloading seems to work normally)
3) For internet streaming video, this means the video will not display until the whole video has been buffered (i.e. will not play until fully loaded)
1) I am on a home network. Other computers (including my old one) do not exhibit similar problems
2) Using Firefox 9.01
3) Win 7 SP1
4) Realtek PCIe GBE controller

I have 2 cat3524xl's and a 3550. I recently did something to the IOS that makes the switch not display any output to the console port. Not sure what I did but even doing the reset as instructed in the Cisco docs by holding the mode button foe 2 seconds after boot. I get the flashing green light but still no output. All POST tests pass according to lights so I tried different cables and all baud rates with no change. I hoocked switches back up in lab and can see them in CDP neibors but do not know how to access them from there as they have no IP assigned to them. Remember this is two of them with exact same issue.

I am running LMS 4.1 and have an issue with Inventory: I have a stack of four 3750 switches, but only two of them are showing up in CiscoView. If I right-click - Topology - Device Report ; I see all four switches. The switches are standard 3750 switches and should be included in the Device Packages for CiscoView
Also if I go Reports - Detailed Device ; I see the same two devices show up under Module Information. However when I go to Reports - Device Attributes ; I see all four devices correctly displayed.
I have tried and deleted and added the stack in CiscoPrime, but with same result.

I'm planning to setup a network with more than 300 PCs. I know that using class C address is not enough to allocate number of IP addresses required. What I meant in the preceding sentence is that If I use this network address 192.168.1.0 (class C), it will allow only 256-2 = 254 IP addresses, What about other PCs in the network ?

I have Windows 7 Home Premium on a Dell Inspiron N5010.
I have had this problem for several weeks, and have searched all over to find a solution (tried them all, but none have fixed it). I have a good wireless internet connection, and sometimes I use ethernet. Despite having such connections, my wireless internet icon doesn't change, as it seems to keep getting stuck on the icon which shows a red x over the ethernet image.
It will show the blue loading ring with the bars as it searches for a wireless connection for a little bit, but then it goes to the same, incorrect icon, even though when I put the cursor over the icon it says "Internet Access".
So far, I've tried deleting the Icon Cache and rebooting, as it was suggested that it could be potentially corrupted, but the internet icon stays the same. I have also tried searching for a driver that could be potentially related to the issue and uninstalling it, but it didn't work. The red x went away for a moment, being replaced by a loading blue ring, but then the red x returned (same icon image).
Is there a specific driver for the icon itself? I know I had to uninstall a driver then reboot to get my battery icon back after it mysteriously disappeared. I also have tried deactivating/reactivating my wireless connection by hitting the button, but it doesn't change.

i create a network topology ( i attached picture) and i don't know what exactly IP addresses should be assigned to routers and switches + there should be five VLAN's created and just one vlan (vlan 2) must see others vlans (for management purposes) and others vlans should not see each other. So i need that: 1) What IP addresses should be on routers and switches 2) How to create a 5 vlans, that they should not see each other, but one should see all, for example where i have to put "tagged" ports where "untagged" or "not member" ports etc.

I have a home network with a Netgear N600 as my main router. I have a wirelesss HP printer that accesses fine as does Iphones and Ipad. Then I have hard wires. Off of the main router I have 3 Netgear 5 port switches. 1 switch with a line to bedroom tv and a line to family room tv. 1 Switch at family room TV which goes to Blu Ray, Direct Tv, and Xbox360. 1 switch at bedroom for Blu Ray and Direct TV. Believe it or not, this all worked. I tried to hook up a ZmodoH264 security system (the ones with four cameras, and a separate hard drive and monitor for viewing). I used one of the 4 inputs on the main Netgear router for this, and it seemed to be recognized. But, I can't access the security system mobilly, AND all my network addresses seem to have been screwed as Directv isn't working (Whole Home) and the printer stopped being recognized. However, Blu Rays are still fine. Is there a way with ipconfig to list all of my hard wired nodes? I assume wireless dont show up in a list.

I have used all the spots on the form to filter mac addresses. Is there some way to add more? I have a lot of friends that come over from time to time. I also have plenty of my own wireless devices.I like using the mac address filter so not using it is not an option. Hopefully there is a way to add more, instead of being limited to a predetermined amount.

I'm configuring a console server for configuring remote devices. This is working well except for the fact that if a target device is in ROMMON mode, the console server refuses to displays the target device console. It does open the connection but the ROMMON prompt is not shown on the console server . This is essential for this device as we will need to use it to reset passwords remotely and thus need to be able to access ROMMON mode from the console server.
Parts used are a 2951 router and a HWIC-8A serial card. Posted my config below:
[code]
Current configuration : 4389 bytes

I've got an issue with SNMP and netflow tools. They are displaying different data for the same (sub)interfaces.I've got metroethernet link which connects root A (Cisco 7606, 12.2(18)SXF8) and root B (Cisco 2811, 12.3(11)TS). MPLS is configured on the link (behind root B there is no more MPLS). I'm attaching root configurations (I've ommited parts of config).Interfaces are:
Root A - gi2/6.2144
Root B - fa0/1
I've configured SNMP and netflow on both devices. I'm using two SNMP tools (CA Spectrum and eHealth) and two netflow tools (CA NetQoS Reporter Analyzer and Fluke Networks NetFlow Tracker) to collect the data. SNMP tools show the same info for defined (sub)interface.Netflow tools also show the same info for defined (sub)interface. I'm attaching reports from one SNMP tool and one netflow tool for the same time period.
1. Looking at SNMP tool, it can be seen quite amount of that data in both in and out direction.
2. Looking at netflow tool, it can be seen quite amount of that data in out direction, while in direction shows small amount of data.
I'm aware that Cisco has difficulties with SNMP counters on subinterfaces. I'm also aware that MPLS netflow has its own difficulties.Root B netflow configuration is quite simple as it has just 2 interfaces to configure netflow on (Fa0/0 and Fa0/1). So I would guess SNMP and netflow data should match, but they don't. When you look at SNMP tool reports for roots A and B, it can be seen that traffic volume is practically mirrored.

I can see what MAC addresses have a wireless session and I've used MAC Filtering to stop some MAC addresses from using the network at certain times, but they are still getting through to the internet. I don't know if they were to clone their MAC address as to whether this would show up with the cloned address in active sessions list. How I can stop some users from getting through at certain times? Any utility I can use on my Mac (Mac OS X 10.6. to show which computers/MAC addresses are on the network?

My boss would like to know if there is a way to find out the ip address of a person VPN ing into our network. Let's say Joe Smith is VPNed in from home and his carrier is cox communications. How would I go about finding out what his ip address (the ip issued to him by cox) is? Is that even possible? If it is possible, is there a way to create a list of ip addresses of everyone that has ever VPN ed into our network? We are using a Cisco ASA 5520 and Cisco VPN Client.

I have set up a private domain network at home. I have a domain controller, a DNS server, and a DHCP server all running on one Windows 2003 Server machine. I have about 10 other machines around the house, getting their IP addresses from this DHCP server.
I have a Netgear WNDR3700 router.
I am about to get 5 public IP addresses from my ISP, and I would like to make some of these machines publicly accessible (while still accessible from the other machines in the network).
I found this link that says on my web server (one of the public machines), that I should use a second NIC and set that up to connect to my router (and get a private IP address from my DHCP server).
