what application/service is sending out net bios broadcasts on a network segment the requests are for machines that no longer are on the network but something is trying to obtain there ip address as they are not in dns any more i am assuming this is why they are resorting to netbios broadcasts i need to some how isolate what application or service is trying to find out.

Low and behold the SG300-28P is sending out quite a few Broadcast Packets. Most of them are the same, ARP Request for its Default Gateway Address. Others are for a few other AD Servers on our network.
Arp Entry Age Out is set to the default of 600000 with "Normal Age Out" selected. Though in a few minutes of logging Packets, there were almost 7,000 broadcasts from it for the its Gateway Address. The Gateway Address that it has is the IP of a Cisco ASA 5510. Is there some TTY on the ARP entry like DNS?

So i tried to find a solution on the web (wierless internet still worked) and stumbeld upon a similar problem were the answer was to manually fill in an adress in the "internet protocol version 4" properties in the "local area connection" properties. I then noticed that i dident have the "Obtain DNS server address" set to automatically and that the other manual boxes were empty. I then turned the auto on an i had access to internet. Is this safe? Cause i read somewere that DNS server addresess were provided by the company that provide you your internet service, and that you can be redericted to a fake website that can get a hold of your account information on it

View 1 Replies View RelatedI have an Avaya IP Phone for work. This has been tested at work and works as expected. After the IP Phone boots it's able to obtain an IP address from work. At home when I plug the IP phone into my DIR-655 router, it's unable to obtain an IP address. Other network devices are able to obtain an IP address, for example any computer or laptop. Also my wireless works with no issues expect for the IP phone. I've already done some searching and found other users with the same issue but I haven't been able to find a solution other than setting a static IP address. I'm curious why this relatively new router won't work with an IP phone. I've played with some of the router settings but it didn't make a difference. Any work around to get the DHCP to work? I'm running the latest firmware for my router: 1.35A Hardware Versions: A4.
View 9 Replies View RelatedI have installed about 2 days ago one Cisco WCS 2504 and 11 APs. Everything is doing well regarding to WEP authentication. But I have a Radius Server that is alson running with some issues on wireless:
- Unless I open network settings and click connect on that config I cannot obtain a valid IP Address;
- Roaming is not working also;
I've had the adapter for a while now, successfully running on XP SP3 with the linksys software. I could see networks, connect to them with WPA security and get an IP address. I recently tried uninstalling the software, then connecting the adapter to install only the drivers and let windows manage it. Since then, I haven't been able to acquire an IP address. It can see the SSID and connect to it, but continually tries to acquire an IP address. I've tried this with different SSIDs at work and home...same result. I've tried uninstalling the driver from device manager, but every time I restart and connect the adapter, windows recognizes the adapter. I probably made matters worse by connecting another adapter to it, in an attempt to work around the problem. That is a USB adapter, WUSB600N. Tried the same thing, but continually tries to acquire an IP address.
View 2 Replies View RelatedI would like to share one problem with WLC 5508 . we added a new virtual interface on the WLC. One new SSID is associated with this interface.
We created a ACL for this interface to restrict the access via WIFI to certian services. It´s not correct that everything works fine because the change were not applied. [code]
The changes of the ACL are applied on the fly, but for reason we don´t know, the clients don´t get a DHCP IP-Address (after changing the ACL) until the Controller is rebooted.
I have a WRVS4400N that brocasts two different SSIDs. One is a public network and the second is a private network. Right now, both SSIDs are pulling from the same DHCP server, but I would like to seperate the public from the private. How can I seperate these SSIDs by vlans? I can't seem to get the vlans to route to sperate ports.
This is my vlan settings. I have two DHCP servers right now. One is in an isolated network plugged into Port 3 of the WRVS4400N. The other is on the production network, plugged into port 1 of the WRVS4400N. For some reason, whenever I connect to SSID Public, it won't pull an IP from the DHCP on port 1, it only pulls it from the one on port 2.I know there is three SSIDs here, the Static one is going to be the same network as the EMS one.
I am trying to connect my WDTV Live to my desktop PC, and I connect to the net through a wireless connection to my router. Because its in the other room, I can't connect my WDTV Live to the router without running cable along the floor. Having said that, its not far away from my desktop PC, so I'm trying to connect them directly via cable. The problem is that my WD keeps telling me that it can't obtain an IP address and I don't know how to fix it or what values to put in.I've tried power cycling, manually setting an IP address (192.168.0.5), using different cables, all with no success[CODE]
View 1 Replies View RelatedMy set up is a 2wire router that connects to the internet, with an ethernet power plug connected to it. Over the other side of the house, I have the other ethernet power plug connected, with a Netgear router in access point mode.The main router is on 192.168.1.1, and the access point is on 192.168.1.3. The DCHP server is enabled on the main router with range 192.168.64 to 192.168.1.253. The access point has the DCHP server turned off. The routers have the same APN and security (WPA2-PSK).Also, the wireless channels don't overlap, channel 1 and 11.Now to my problem:The internet always works fine for a few days when the routers are turned on. But at some point between 1 to 3 days later, every computer can't obtain an IP address while connected to the access point. But all computers can connect to the main router (i.e. when closer to the main router than the access point), and then go near the access point and it keeps the connection. If I reboot the access point, then everything works again for a few days.

The thing is i configured it correctly, well at least i think, i can see it on my wireless network, with a good signal, but on my Android tablet (Google Nexus 7), it can't get past the "Obtaining IP address".
I called the technical support, the person there tried to assist me for about 1 hour, we tried different settings, we upgraded firmware from 1.0.01 to 1.0.04, but it didn't worked. Now he said someone will call me tomorrow during the afternoon.
My router isn't Linksys, it's a Netgear, i don't have wireless problem when i connect my tablets or any other wireless device on it, it's just that i bought this WAP610N to have the signal in my bedroom, where i don't get any signal normally.
I tried many times to connect my ps3 to the internet/playstation network so far no luck. The router I'm using is a linksys WRT54G v 2.00.8. I have no problem using my WII, PSP, or computer to go online but my ps3 cannot connect to the internet.url...The errors I might sometimes get is "failed to obtain IP adress" and most of the time I get something with unable to connect to internet server when I am able to get the IP address
I was thinking maybe I shold reset my router to default settings but I'm not sure what's the way to do that or update the router? This problem also has been happening for a week now. In the previous weeks I could easily connect to the internet with no problems and all of a sudden I cannot connect anymore and this has happened a few times already in the past where I am unable to connect to the internet with my ps3 for a few days to a week.

I'm trying to connect my Xbox 360 to Live by bridging my computer's wireless connection. I've done this before for a friend in a different city and it worked fine, and I felt very proud of myself for doing so. However when I try to connect here, the modem won't assign my Xbox an IP address. I've been into ipconfig/all and tried to manually assign the same IP address to the Xbox but to no avail. Same deal with the alternate MAC address option.
To speed things along here's the readout from my ipconfig/all:

I have a strange behavior between a WLC 5508 (version 7.0.116.0) and NEXUS7010.
WLC
The WLC is configured in DHCP Bridging Mode (it sends DHCP requests without change)
Nexus
The VLAN interface is configured as follows
interface Vlan501
ip access-group acl-int-vlan501-in-1 in
no ip redirects
ip address 10.12.56.4/21
ip ospf network broadcast
ip router ospf 100 area 10.23.0.0
hsrp 51
Clients can not obtain an IP address intermittently. If I deactivates the ACL when the problem appears(when the client can not obtain an IP@) the probleme is resolved
Note: Before the WLC was connected to Catalyst 6500 and worked properly for 2 years (with same configuration)
I saw this note about differences between DHCP relay on the NEXUS7000/NXOS an Ip helper one the 6500/IOS URL. Do you think the problem may come from the DHCP relay or ACL on the NEXUS.
2 days ago, my laptop was connected to my router and working fine. But it then randomly disconnected and haven't been able to connect back since. I am using an ethernet cable to access the internet, and have tried many ways to try and resolve the issue but nothing is working.
I have a Dell L501x (Win 7 64-bit) with the Intel Centrino 1000 BGN wifi card. I have restarted the router and modem and disconnected all devices and tried reconnecting, but to no avail. I have tried updating the drivers, system restoring and using safe mode (with network) but nothing works. The modem and router are working fine as other devices connect and access the internet, it is just my laptop that cannot.
I am sure it is not a hardware issue as the card detects all the surrounding networks. The troubleshooter only says "An administrator profile failed to obtain an IP address from the DHCP server.
I just got a new RV042. V3 Hw.For setup and testing before putting it in action, I've attached the WAN1 side to my internal network.But it fails to get an IP address, and the log shows: "Infinite lease time, exiting".My current router on the LAN is giving out DHCP addresses with 3 hour lease time, and I've checked with the PC's on the LAN that this is correct.The routers DHCP status shows that the lease time for the RV042 is 3 hours ahead.So why does the RV042 complain about long lease time ?Is there a way to avoid this error from occurring?
I have tried to change from 'Gateway' to 'Router', but this does not change anything.Also tried a factory reset, with no luck.Fw is upgraded to the latest 4.0.4.02
Well I went to command prompt and typed command ipconfig /all and saw the ip address my system was configured to. Dunno why, but I manually set that ip address in my IPv4 internet settings and got access in my hostel. Now suddenly the access is gone. What should I say, the ip address that I set my laptop to has been shut down ? It doesnt work any more? How do I get another IP address like that which gives me no restricted browsing? What does the admin do in the laptop that suddenly it gets unrestricted browsing privileges?
