Synchronize Two Wireless Cards Having Same Mac Address
Feb 15, 2012
What I meant is that I am trying to implement a system that uses two wireless cards to enable a user to move from one access point to another without droping the call because the handover should take a maximum of 50ms (miliseconds), that is why in this approach two cards were use so while one is scanning for new access point the second one will still communicate in oreder for the call not to be drop and this action will keep going anytime where there is a need ofhandover?

We want to configure the "mac-address-table synchronize" command on our 6500 series switches to ensure that the CAM tables on our DFCs are in synch with the PFC on the supervisor modules. url...it is recommended that we disable the routed MAC purging with the mac-address-table aging-time 0 routed-mac global configuration command. What is a routed mac entry? Are there any issues with running that mac aging-time command?
We also plan to run this command "mac-address-table aging-time 14400" to keep our ARP and CAM tables on the same aging time to reduce unicast flooding on our network. Can we run this command with the "routed-mac" command above?

I have a problem with my 802.1x Solution in ACS Version : 5.2.0.26. The hours between my ACS and the AD lost synchronize, for that reason the user in my network can't authenticate in the Solution. when i see the hours was different for the AD in 5 minutes, i have to force again the common ntp server 172.25.0.34 (which is ip ntp server). I don´t know why is the reason for lost synchronize, maybe could be a bug.. or samething that i have to configurate in the ACS or AD.

Today I have configured my ACS 5.2-0.26.4 to synchronize with NTP server which is implemented in Cisco 6500, but it don´t become to work. The switch Core is configuared in HSRP, for that reason in the ACS server I defined the IP virtual of the Core like ntp server, maybe the ACS don´t work with IP virtual of the switch Core. Finally I wanto to kown if is posible to synchronize this versión of the ACS withc cisco 6500. I had integrated this ACS versión with cisco 2800.. maybe the ACS could integrate with same special models.

I switched from Time Capsule with AirPort to E2000 and have a problem with configuration.I use the same IPs as in AirPort and E2000 gives me an error:"The WAN IP address cannot be the same subnet as the Guest Network IP address" and I can't save configuration.But in my opinion they are different.I use "Static IP" option and I have IPs from my ISP: [code] So WAN IP is different subnet as LAN and I don't know what to do now. It worked with these settings in AirPort and here I can't proceed.

Driver software is from 2009 and it says there are no updates found,. RALINK TECH. CORP is the manufacturer and microsoft is the driver supplier, although neither website has anything for my piece of equipment (i have installed updates from both of them and my driver software is the same as before). How do I find updates for these drivers? When I search online all I get is driver update programs that cost money to use.

I have a Dell laptop with a Wireless-G modem built in. Is there any point in getting a USB Wireless-N modem to speed up the overall connection? I don't know if my Cox cable modem service is even fast enough for it to matter.

I have attached screen prints in various formats.The machine is a PB Easynote TM01 laptop running Win 7, using built in wireless and for some time I have been exeriencing hit and miss internet/network wireless connections.With my limited knowledge I have managed to identify that two of the network adapters are not showing in Device Mnaager when there is NO connection but are showing when there IS a connection.I think this indicates a faulty (or knackered) network adapter.I now have no connection whatsoever and haven't for about a week.I have plugged the machine into the modem now and internet is fine, but what is the point of having a laptop that can't sit on your lap when it is plugged in.

My wireless card on my gateway laptop isn't working anymore.I have already tried uninstalling and all of that. I am just going to replace it. I currently have a Intel 3945ABG network card. Is there another network card I can replace it with that is more efficient and quicker? Not sure what other information is needed to figure out what network cards are compatible.

My girlfriend's computer has quite suddenly developed the problem that the wireless card simply will not turn on.She has an Asus Notebook G60 Vx Series, which has a switch on the front as well as Fn+F2 for turning wireless on/off. Yesterday, she noticed it wasn't working even though the switch was "on", but was able to use Fn+F2 to enable it. Today, neither will work. It simply won't turn on.Ethernet works fine when connected directly to the router. Device manager detects "Intel(R) WiFi Link 5100 AGN" as working correctly and drivers as up-to-date.I feel like this must be a software/driver problem, but everything seems to be checking out. [code]

I thought i would clever and make an extension from my Virgin Superhub via Ethernet to a second pc that is currently using Wireless to improve speed.The amazing thing is the ethernet cable I made up actually seems to work but only when my wireless connection is on. If I disable my wireless to use just the ethernet I get no connection showing!If I click on properties it shows I am connected at 100mbps but I presume this is just the connection between the Hub and the pc although my Internet connection dialog also shows 100mbps.In the Services dialog I can add services which I presume would give me access.I have my ip address but do not know the name of the service I should be running (DCHP?) or the Port numbers.In addition to this there doesn't seem to be a network card appearing in device manager other than the wireless dongle.

I have a laptop connected to an home router through its built in wireless card. It has checked the "share internet conexion" option. I can browse on internet with this laptop.The same laptop have another usb wireless card configured as ad hoc with the other(s) computer. This second computer is communicating with the first one, but the router does not answer the ping call (and I cannot browse on Internet with this computer either).

I have a HP nc6120 laptop and I recently switched the hard drive. I installed Windows XP professsional and downloaded drivers from HP homepage (also did a BIOS update)
Local connection via cable is OK (broadcom netxtreme gigabit ethernet) but there isn't wireless connectivity. I downloaded all the wireless drivers, but still HP wireless assistant offers only Bluetooth connection and there isn't a wireless card on the device manager list.
Some time ago, as I formatted my previous drive and downloaded the same drivers from HP homepage, the wireless connection worked like a charm

Recently my wirless internet stopped working. I am running a HP dv 9000 laptop. The indicator light always stays amber (instead of turning blue when turned on) on external wirless switch. The wireless adaptor should be a Broadcom 802.11b. This does not show up in device manager, but my computer says the driver for it is installed. In the device manager there is one device with a yellow question mark beside it called "other device". Under this device there are three more devices called "base system device" with a yellow exclamation point next to them

Now my problem started happening after my desktop computer got unplugged. When I booted back up, I was unable to connect to my access point. Or find any of the other networks it can always see. I took my laptop and set up an ad hoc network and it came right up. The wireless access point has not been changed and it is perfectly fine. I've updated the drivers from Ralink, nothing. Uninstalled and rebooted, nothing. Checked the BIOS for any settings, nothing. Made sure the radio was turned on, nothing.

I purchased a computer with a pre-installed wireless card which was stated to be b/g/n compatible. When I go to setup a connection to the wireless network (through a Netgear WGR614 v8 router), it has no problem detecting it with a full five bars. However, when it prompts me to enter the password I do, but immediately afterwords another password box appears prompting me to reenter the password again. After repeatedly doing so, it will eventually say the password is incorrect. I know the it is correct because I've since purchased a Netgear USB adapter for temporary purposes and it connects using the password. I've even accessed the router to ensure the password I was using was correct and it is.

I have a client who has 4 computers in the house all running wireless. 2 desktops and 2 laptops. One of the laptops is running XP and after 5-10 minutes of surfing, the internet stops working while all the other computers retain a good internet connection. Repairing the connection via the taskbar icon fixes it temporarily until the issue reoccurs.

I just moved into a new apartment and I bought a usb wireless adapter so I could make use of the virgin media broadband. I've only ever used the internet on this computer via my ethernet connectionI installed the network adapter with no problem (using the CD included in the box) and it appears in my device manager and is working correctly. However, when I look look at the available networks I can only find BT Openzone (it's a pay as you go service, I'm using it now to try and fix this ), and some random BTHomeHub. I should be able to see a lot more, including my Virgin Media network, but I can't. It was the best 'Dongle'[?] in the store, so I'm guessing it's not an issue of proximity. I'm also certain that the network should be publicly visable. [CODE]

My sister has just purchased a custom built desktop computer that will not connect to the household network. We have various other computers and devices that connect to the router (Thompson Gateway TG782T) without any problems. Just to be sure I've tried reseting the router to factory settings to no avail.
I've tried connecting her computer to the network through the TP-Link Wireless Adpater (TL-WN881ND) that came with her computer AND through a Netgear Wireless USB Adapter (WG111v2). In both situations the network is detected, the network password is requested (and accepted) but the result is always that she has 'limited connectivity', cannot access the internet and cannot detect any shared network drives.
I've tried connecting with an Ethernet cable as well, which her computer does not detect at all ('network cable unplugged').When I try to troubleshoot any of these problems I get a message that says 'The Diagnostics Policy Service is not running'.The guys at the shop where my sister had it built are asking her to bring the computer in with the router becuse they are convinced that the machine is fine, and that the router is at fault. Some Specs for her computer

I have 300Mbps PCI wireless LAN network card which I installed in my PC and until today I was connected to my Sky router wirelessly. I also have a wireless Brother all in one connected to the same PCI card.
The engineer who installed my Sky fibre broadband told me in order to achieve maximum speeds I should connect via an ethernet cable to my Sky router as wireless could be a lot slower so I bought one and connected up and disabled the wirelss card. All good so far until I noticed my Brother all in one was complaining about no network ID.
My problem is that I can't seem to run my printer wirelessly as well as run my broadband wired. If I enable the wireless adapter the printer works but my broadband is wireless as well and the wired connection is disabled.

url...My wife was using her Toshiba A215-S5837 and all of a sudden, wireless goes out. No networks to be found. I've tried any number of drivers I could find. I have also tried using the driver as suggested by many places (including the previous thread), found on the CZ site. No luck. I just tried safe mode and updating to no avail. Though Windows 7 is not kind about letting you install a driver initially. I uninstalled, and plug and play took over so I was forced to do it via update.

I built a computer a while ago, from a reasonably low budget. Ever since the very first boot up, the wireless card (TP-Link, unable to find model currently, will add later) only works on the second consecutive boot up. I have no idea why, I have not found anything relating to a problem like this, the computer doesn't even appear to know that there is a wireless card in it. Instead the icon shows a cable, suggesting that the computer isn't connecting with the card.
