Wireless roaming in different networks

Hello,
In Wireless networks if we have two different networks with the same SSID when we pass from one network to another network, the client will change the ip network automatically or we need to disconnect and connect again to request another ip?
I would like to know this information to Flexconnect and local.
Thank you.
Best Regards
Cristiano Nunes.

Hello Cristiano,
You don't need to disconnect and connect again if you have Layer-3 Roaming enabled.
To configure Layer 3 Mobility, following requisites should be considered.
SSID and security policies should be same across MAs.
Client VLAN ID should be different for Layer 3 roaming.
Either one or both of the bridge domain ID and client VLAN ID should be different for Layer 3 Roaming.
Please find the attached topology for better understanding.
Regards,
Moin Ilyas.

How do I set up different network locations with different wifi?

I am having an issue setting up different network locations with different wifi profiles on each. I want to do this to enable fast switching of wireless networks. In my house I have two wireless networks, my own personal one and one that is created by using a wifi modem supplied by my company. If I use the company wifi network then I can get into all my work applications without having to enable VPN access separately. It is also faster. However, they also block many applications including sending email from my personal email account, dropbox, etc. So throughout the day I need to switch wireless networks back and forth.
I was looking for a faster way to switch and thought I would try network locations. Was able to set up a new network location without issue. However it seems that whatever wireless preferences, changes, or wifi network order I put into my "Work" location it carries over to my other location which is the standard "Automatic".
What I would like it to have my "Work" location only to be able to connect to my work wifi and my other network (Automatic) to just connect to my home wifi only. That way I can enable faster wifi switching and can even use my launcher program (Alfred) to provide shortcuts.
Anyway to do this?
Thanks in advance for any help or advice.

Just thought I would bump this up in the conversation. Doing a further search I came across this discussion which is similar: Connecting to a wireless network via applescript?
However, I tried to build the Automator application as discussed and cannot get it to work. Very much a novice at Applescript and Shell Script but have created customized Automator services before. All I get now is "Shell Script command encountered an error". No more detail. I copied and pasted the script as shown in the email thread. Is there any other line or command I need to place in front of it?
Thanks again for any help

I have one modem in the house but I need 2 different networks.

I have one modem in the house but I need 2 different networks that will not communicate or even see each other. The first network is the one that needs to be the most secure. The computers are used for personal information, documents, pictures, Apple TV and iTunes home sharing.(3 Apples, 3 iPads, 3 iPhones and 4 Apple TVs) The second network needs to be for the 3 computers and gaming systems used for social games on Facebook, PSP, XBox, and a gaming system used for World of Warcraft. The social interactions seem to be the ones that have picked up most of our computer network issues and I would like to be able to isolate them from any communication with our home network (2 PCs and 1 Mac). Is there a way that I can use 2 different routers along with blocking any bluetooth and/or bonjour connections? I am not worried about a networked printer for the second network, it is more to try and contain any issues that may slip though virus protection and create a mess with our home systems. It would be nice to still be able to set up a Guest Network for the herds of kids and adults to use when visiting as well. PLEASE tell me this can be done.
Thank You
Christine

Christine,
Apple may be able to do some, but not all of what you want to do.
The dual band AirPort Extreme can create a main, or "private" network and a separate "guest" network. The private network can be configured to handle both wired and wireless clients. The "guest" network works only for wireless clients.
Computers, devices, etc on the "guest" network cannot "see" or communicate with any of the devices on the main or "private" network. But, it is possible to allow clients on the "guest" network to see other devices on the "guest" network, so a wireless printer on this network would allow anyone on the "guest" network to be able to use the printer if you need that functionality.
You can "extend" the "main" network using more wireless devices if you need more wireless coverage. The "guest" network cannot be extended.
Depending on the level of service you have with your ISP, you may have bandwidth issues with two networks and multiple devices all trying to use the Internet connection. I would think that a 25-30 Mbps connection would be the bare minimum to handle what you want to do and 50 Mbps would be advised.
If you want to use two separate routers, you are really looking at a commercial type installation best handled by commercial products like Cisco, so that might be the place to look.

Best Practice for FlexConnect Wireless roaming in MediaNet environment?

Hello!
Current Cisco best practice recommendations for enterprise MediaNet design, specify that VLANs be local to a switch / switch stack (i.e., to limit the scope of spanning-tree).
In the wireless world, this causes problems if you want users while roaming to keep real-time applications up and running. Every time they connect to a new AP on a different VLAN, then they will need to get a new IP address, which interrupts real-time apps.
So...best practice for LAN users causes real problems for wireless users.
I thought I'd post here in case there's a best practice for implementing wireless roaming in a routed environment that we might have missed so far!
We have a failover pair of FlexConnect 7510s, btw, configured for local switching for Internal users, and central switching with an anchor controller on the DMZ for Guest users.
Thanks,
Deb

Thanks for your replies, Stephen and JSnyder.
The situation here is that the original design engineer is no longer here, and the original design was not MediaNet-friendly, in that it had a very few /20 subnets bridged over entire large sites.
These several large sites (with a few hundred wireless users per site), are connected to an HQ location (where the 7510s in failover mode are installed) via 1G ethernet hand-offs (MPLS at the WAN provider). The 7510s are new, and are replacing older contollers at the HQ location.
The internal employee wireless users use resources both local to their site, as well as centralized resources. There are at least as many Guest wireless users per site as there are internal employee users, and the service to them consists of Internet traffic only. (When moved to the 7510s, their traffic will continue to be centrally switched and carried to an anchor controller in the DMZ.)
(1) So, going local mode seems impractical due to the sheer number of users whose traffic bound for their local site would be traversing the WAN twice. Too much bandwidth would be used. So, that implies the need to use Flex / HREAP mode instead.
(2) However, re-designing each site's IP environment for MediaNet would suggest to go routed to the closet. However, this breaks seamless roaming for users....
So, this conundrum is why I thought I'd post here, and see if there was some other cool / nifty solution I wasn't yet aware of.
The only other (possibly friendly to both needs) solution I'd thought of was to GRE tunnel a subnet from each closet to the collapsed Core / Disti switch at each site. Unfortunately, GRE tunnels are not supported in the rev of IOS on the present equipment, and so it isn't possible to try this idea.
Another "blue sky" idea I had (not for this customer, but possibly elsewhere in the future), is to use LAN switches such as 3850s that have WLC functionality built-in. I haven't yet worked with the WLC s/w available on those, but I was thinking it looks like they could be put into a mobility group, and L3 user roaming between them might then work. Do you happen to know if this might be a workable solution to the overall big-picture problem?
Thanks again for taking the time and trouble to reply!

Can I setup "Roaming" and "Extended Network" on the same device?

I have 2 buildings that need wifi coverage. In the main building, I have 2 Apple Airport Extremes. I have one as the main router. The 2nd has a network cable from the 1st unit and is setup as "Roaming". I would like to add "Extended Network" (wireless) function to the 2nd unit. Then I would place a 3 Airport Extreme at the 2nd building. I have signal at the 2nd building, but I would like it to be stronger.
Can I setup an Airport Extreme with Roaming and Extended Network functions and if so, how would I do it.
Thank you.

Yes, that should be no problem.
Windows 7 uses 5.6 airport utility.. what model extreme are you setting up??
But it is relatively simple.. you do not need to generally do anything now for the AE setup for roaming..
On the one you will extend, simply plug it into a computer.. run the airport utility.. go to the wireless tab and put in the extend wireless with the name and security of the wireless you are extending.

Error The PC and the printer are connected to different networks

Hi,
I'm trying to set up my C4580 on my laptop, but I'm getting the following error after the diagnostic test:
The PC and the printer are connected to different networks(237DB2A87D and 66616B65). They must be connected to the same network. This can happen when you use the manufacturer's default network name (SSID) and another nearby network is using the same name.
My setup is a Linksys router WRT546, my laptop is conntected wireless to the router. I have two other desktop computers that are directly connected to the router. Both the desktops are able to connect wireless to the printer. My router SSID name is 'Blair Office' with WPA security.
I get a internet connect fine with the laptop, but can't get the new printer to setup.
I saw another post that talked about 'Print the C45** Network Configuration Page', but not sure how to do this
Thanks
Diane

This reply may be late for this user, but it might be helpful for any current users.
I managed to change the modem's IP address to match that of the printer. In my case the printer worked fine wirelessly until I moved to a new place and installed a new modem. Here is what I did to solve the problem:
1. At the printer, click on the wireless button, wireless settings, print network configuration page. This will print a page with the printer's IP address (in my case: 192.168.0.13)
2. I accessed my modem via the internet browser, typing 192.168.1.1 (this is one of the default addresses (192.168.0.1 is also common). Default user and password is admin (usually). There I changed the modem's IP address to 192.168.0.1 and the range to start at 192.168.0.13 (my printer's IP address).
3. I saved the settings (the modem will reboot and you will be offline, it may take some 20 seconds before the modem is visible again).
4. Reconnect to the modem and check if internet is still working. Then try to install the printer again.
This worked for me after I read several other postings.
Good luck!

[Question] Dynamic NAT on 2 different networks

Hi,
I just want to ask if its possible to have same dynamic translation within 2 different networks like:
interface gig 0/1
1.1.1.1 255.255.255.0 (LAN Connection w/ DHCP enabled)
inteface gig 0/2
2.2.2.1 255.255.255.0 (Wireless Connection w/ DHCP enabled)
Actually, the scenario was 1.1.1.1 is my LAN connection and 2.2.2.1 are my Wireless connection.
Hope this merits their favorable response. Thanks.

Hi,
Do you mean that you want both of the said LAN networks to use Dynamic NAT/PAT towards a third interface on the ASA?
If you simply want to use the same NAT/PAT address for 2 different networks on the ASA then you can use the following configurations as example
These are PAT translations to a single IP address. Using a NAT Pool would change the configurations slightly.
For ASA software 8.2 and below
global (outside) 100 3.3.3.1
nat (inside) 100 1.1.1.0 255.255.255.0
nat (wireless) 100 2.2.2.0 255.255.255.0
Where
outside,inside and wireless = Interface "nameif" on the ASA firewall
100 = Is just an ID number for the NAT configuration. You can use other one also
For ASA software 8.3 and after
object-group network PAT-SOURCE-NETWORKS
network-object 1.1.1.0 255.255.255.0
network-object 2.2.2.0 255.255.255.0
nat (inside,outside) after-auto source dynamic PAT-SOURCE NETWORKS interface
nat (wireless,outside) after-auto source dynamic PAT-SOURCE NETWORKS interface
Where
PAT-SOURCE-NETWORKS = Is an "object-group" where you can define the source networks for the NAT/PAT rule
Hope this helps Please if you found the information helpfull
Feel free to ask more if this didnt answer your question.

You don't have to be connected to the same network in order to transfer files – your devices automatically set up a direct wireless connection for AirDrop.

Can an airport extreme base station attached to another airport extreme base station as an extender transmit a different network name and have it's own security?

Can an airport extreme base station attached to another airport extreme base station set up as an extender transmit a different network name and have it's own security?

No. The AirPort cannot extend another AirPort's wireless network and simultaneously broadcast its own wireless network.
It can however, be connected to another router (including another AirPort) by Ethernet, and then, be configured to broadcast a wireless network with another Network Name and Security Type.

C4780 PC and Printer on different networks

Please help - I have just purchased a C4780 wireless printer, for a home with 3 laptops. Two of the laptops have been set up fairly easily to print wirelessly, but for the third I am getting the following message :
The PC and the printer are connected to different networks(192.168.103.0 and 192.168.1.0). They must be connected to the same network. This can happen when you use the manufacturer's default network name (SSID) and another nearby network is using the same name.
We have only one wireless router, a Linksys with SSID Linksys-6102, and that is identified on the printer's network test report, ( the only other listed is one called NETGEAR ) and also on the third laptop, as well as both of the others.
The router's IP address is 192.168.1.1
The printer's IP address is 192.168.1.104
One of the successful laptop's address is 192.168.1.102
The one I'm having a problem with has address 192.168.103.1
Can anyone help suggest a solution?

It sounds like the printer is on your network (Linksys-6102), but the third PC may be connected to a neighbor's (?) wireless network named NETGEAR. It the third PC is connected to a neighbor's network, it will not see anything on your network.
Your neighbor probably has a NETGEAR router with no security, which is a huge risk for them and a pain for you since your PC's will sometimes jump onto it instead of your own network. If you know whose it is, talk them into changing the SSID and adding WPA or WPA2 security to it.

IPv6 Network Flood with Wireless Hyper-V Virtual Network

Recently, on our core switch (also our layer 3 router) we regularly see a high cpu load. This cpu load is the cause of packet loss and bad connections. This is happening for almost two weeks now.
Network inspection shows us that there is a flood of IPv6 Neighbor Advertisements originating from what seems the same IPv6 Address but from different Hardware (MAC) addresses. In each second there are up to a 1500 packets per second advertising
the same IPv6 address. See below for more details about these packets.
Tracing the MAC addresses to their owner learns that all clients are using Windows 8 with Hyper-V and that they have an External Virtual Network bound to their Wireless/WiFi Network Adapter. Removing this virtual network stops sending
those packets. Because multiple hosts are involved it may be necessary to remove this network on all of these hosts.
As is visible in the following packet dump this is an unsolicited neighbor advertisements, resulting in an update in the neighbor table on our IPv6 router. These updates are probably the course of the high cpu load.
Frame: Number = 188594, Captured Frame Length = 86, MediaType = ETHERNET

     Length: 1, in unit of 8 octets
     Address:
00-24-D7-76-C4-68
Because the target address is the same in all packets but the MAC address changes, it seems that there is something on the hosts that is forwarding/proxying these packets (and only those packets) back to the network it came from, but only
after changing the targetlinklayeraddress in the advertisement. This process is described in
RFC4389.
One host with this problem on the network will not resolve in a flood. Only when more hosts with this issue are active the flood occurs. It seems that two or more hosts are required to magnify the packets send by the others.
Hyper-V on Windows 8 makes use of a Network Bridge in software to enable the use of wireless network adapters. Is this the cause of all those packets?
Some of the hosts also had Windows Phone 8 SDK installed. The installation of this SDK enables some networks in Hyper-V. Maybe some configuration change is made enabling the proxying of those packets back to the network they came from?
After removing the SDK the hosts are still transmitting too much packets.
The first occurrence of this flood was on the day after Microsoft’s update Tuesday. Is it possible that one of the updates may be the cause of this? There is one mayor update
KB2770917 which includes updates to DHCPv6 and NDIS library’s. Again, removing this update does not solves the problem.
Updating our switch/router to a higher level of firmware may lessen the impact, this is something I can try. But it shall not solve the problem, the switch is not the source of the packets.
Hopefully somebody recognizes this issue. All ideas are welcome.

Martijn

Hello today we have a little breakthrough. Our Accesspoints are connected to a Cisco C2960S Switch. We have enabled storm control on the switches. This blocks only the multicast packets that were flooding the wireless and the wired network.
We determined this using PRTG snmpv2 connection to the Cisco. Whenever the network flooding was occurring the packets per seconds went in the thousands. We now have put the following code on the Gbit interface: (The last line with the storm-control setting
fixed flooding the network at least partially because the multicast packets cannot leave the Accesspoint to travel to other accesspoints or to wired devices.)
Hope this helps others as well.

How to use two different network cards on RT?

Hi everyone... I'm currently working on a project where I have to deal with the issue mentioned in the thread's topic: I have a PC with RT LabVIEW that has to be able to establish network connections using two different network cards. One will be used to connect via TCP/IP with a host computer that will show the data transmitted through shared variables; the other will communicate with another PC through Modbus protocol. The key is that each communication is done through a separate network card.
So far I haven't been able to figure out how to configure both things to happen. Does anyone know how to do this? Any tips will help.
For the RT communication I'm using a standard RT project, with the RT PC being given one of the IPs, and for the Modbus part, I created an I/O server with a master and a slave. Separately everything works fine, but when I get them together it simply won't work.
Thanks for your help!
Solved!
Go to Solution.

Sorry it took me so long to answer, I've been busy lately....I've found a solution to the problem I mentioned, and just in case anyone has similar problems in the future, I'll shortly describe what happened.
As Caseyw suggested, it was necessary to enable both network cards through the Measurement and Automation Explorer. The cause of the connections malfunction was actually that I wasn't using the "right" protocol for the Modbus communication, which ran on the secondary adapter. The solution was to use the URL protocol with the correct path on the field, addressing the right IP address. To avoid making this post a mixture of topics, I won't elaborate futher, but I got the gist of it, so if anyone is having similar problems whether it is working with several network cards or with Modbus communication protocols, feel free to contact me, I'll be glad to help.
Thanks

When i put my own contacts into my iphone 3gs and deleted existing ones, the same happened on my mums iphone 4? my iphone was hers previously, but has been unlocked by o2, we have different networks and were 12 miles apart when i did it!

My mum upgraded last week from iphone 3gs to iphone 4, I got the iphone 3gs unlocked as of this morning and proceeded to remove her contacts and put my own in.
Several hours later she came home from work to find her contacts on the iphone 4 had been replaced with the same list i had put on mine!
We have different networks, different itunes accounts etc, I can't understand why or how this has happened or most importantly how to fix it as she has lost all her numbers and is understandably very very cross....

contacts are not visible in back up, but if she restores from that back up - contacts will come back to phone. Then all her apps and music have to be synced back again. She will also have all other personal info return to the phone, but all that info will be as old, as back up itself.

How do I access a USB server on a "different network segment"?

I have tried posting this question in the Server community but with no response, however I believe the solution will be achived through Terminal and I believe there will be those versed in the use of Terminal here, so here goes.
I have a USB Server with four ports attached to my ethernet LAN. If I enter the IP address into Safari it shows me the Server details and the details of any item attached to any of the ports. However I cannot access anything on the server. If I put the IP address into Connect to Server I get an error message. Apparently the Server is on a "different network segment". How can I overcome this?

MyBook USB=junk.
If you search the forums you will find many users with problems with this particular brand.
Does this drive have an external AC power supply brick? If not, Apple recommends the use of a powered USB hub.

How can I read published data from a datasocket server running in a different network?

Hi all,
I have been trying to solve this problem but without any success. I want to develop data acquisition Vi to run on a computer on a remote location. I want to use the datasocket technology to acquire and publish this data so that in my office (in a different network), I can read the published data and perform analysis with it. I can successfully use this approach for the two computers in the same network but not when they are in different networks. My real problem is how to specify the URL for the acquisition computer in one network while the analysis Vi runs on a different network.
I have attached two Vis to illustrate my point (I simply want to be able to read the random numbers generated in the acquisition computer in a different network). The first Vi (RemoteDatasocketWrite.vi) will run on the remote computer with an IP address (192.168.0.110). My office computer on which RemoteDatasocketRead.vi runs has an IP address (192.168.0.11) and I can log in remotely into the remote computer using Remote Desktop Protocol with name (emelvin.001.eairlink.com) from my office computer.
Is it possible to do what I am trying to do or is there a simpler way to solve this problem?
I will really appreciate any help towards a solution to this problem.
Thanks

Are you getting an error? The way you have it set up, you can have an error and it will never be displayed. Put and error control on your front panel and see what it gives you. Also, shared variables in a project can be useful. Look at some examples for that.
