New WLAN in 7.2 WLC WPA gtk-randomize State?

What does the option WPA gtk-randomize State do when configuring Layer 2 Security under a new WLAN in a WLC (Code level 7.2)?
Thanks

I know this is an inside only attack but a lot of attacks already happen from the inside. Attacks are not always to gain access to a network to use it but to steal information from other trusted users.
In our environment, a University, we feel that this inside attack is very real especially when running ethical hacking courses which probably cover such attacks. Some students will try these attacks out on the most convenient network they have available, ours. So although the user must already have access to our WLAN it doesn't mean that an attack will not happen.
We have a lot of "trusted" users, about 20,000, but to be honest I don't trust any of them.

Iphones and WLC - WPA

Hello All,
Having a nightmare with iphones connecting to 2504 WLC. I have WPA setup with PSK and laptops non apple connect ok. My iphone is saying unable to join. I roll back to No Security and iphone connects ok.
Seams to connect ok on native Vlan with WPA enabled but on tagged Vlans unable to join with Security. Strange.
Running 6.1.2 on iphone
WLC
Software Version
7.4.100.0
Field Recovery Image Version
Any ideas? I've turned off Aironet on the interface with tagged vlan but no change.
Kindest Regards
David

Thanks for responding Scott
Tried WEP and no joy either.    Just resetup WPA and not connecting see below settings
Thanks

APs disappearing after enabling a new WLAN

Hello,
We have a 4402 WLC running software version 4.2.207.0. There are 5 WLANs enabled and we have 13 AIR-AP1010 accesspoints connected to the WLC.
The WLC was recently upgraded from version 4.0.206.0 to provide compatibility with the newer WLCs. The upgrade went without any issues and the system was stable after the upgrade.
We are about to create a new wlan and problems start when we enable it: the system becomes unstable, accesspoints are disappearing randomly. We tested this with two different wlans to eliminate setting issues. The sympthoms were the same in both cases. If the new wlan is disabled everything returns to normal operation and the system becomes stable. All accesspoints are working fine.
I would like to ask your help if you experienced such issue or know a resolution for this.
Thank you!
Regards,
Peter Gombas

Being new to iBook publishing I need to know if stats are available to determine how many times my iBook has been downloaded. Can anyone help please? I need to persuade someone that this really is worthwhile. Mr Ignorant.

The only people who can possibly assist you with this is Apple Customer Relations, call your local Apple contact number and ask for Customer Relations then explain your situation clearly and politely (be firm but don't rant).
You might want to investiage what the local laws are regarding defective goods and 'fit for use' definitions on warranties etc. Consumer Protection can be a useful tool to use or bargain with if needed ...

I bought a new computer and tried to authorize it. It states that I already have 5 computers that are authorized. I no longer have any of those 5 computers. How do I deauthorize all of them, as it is not shown as an option, as my new computer since it is not authorized.
Thanks

You can de-authorize individual computers, but only by using those computers. The only other option is to "de-authorize all" from your iTunes account.
1. Open iTunes on a computer
2. From the Store menu, select "View my Account..."
3. Sign in with your Apple ID and password.
4. Under "Computer Authorizations" select "De-authorize All".
5. Authorize each computer you still have, as you may require.
You may only do this once per year.
After you "de-authorize all" your authorized computers, re-authorize each one as required.
If you have de-authorized all computers and need to do it again, but your year has not elapsed, then contact: Apple - Support - iTunes - Contact Us.
For more information on authorization and de-authorization: iTunes Store- Authorize or deauthorize your Mac or PC.

Create a new rule for printing form to use in time statement form

Hello,
we need to print an information on time statement form in dependence of a special substitution. Is there any possibility to create a new rule for printing form to use in time statement form? I can't find any information about this.
Thanks for your help.

New WLAN(s)

Last year we had a glut of resources. I purchased a 5508 WLC with a (50) AP license, (12) 1042 APs, and (12) 3500 APs. We already have 6 APs in the field run by a 2106.
What I would like to do is supply wireless access to all of the laptops and iphones that are corporate, and also provide guest access. At the same time, I would like to make the lives of the outside workers who maintain a VPN connection all day in the home office a bit easier with Office Extend.
So - I'm at a place where I don't know where to begin. That is an excellent place to start I think
I would like to deploy in stages - replace the current infrastructure, provide guest access, and have the remote users connected in stages. It's all about how to get started at this point.
Thanks,
Ed

Hey Ed,
I would recommend you check out some of the Smart Business Architecture (SBA) documentation at http://www.cisco.com/go/sba/. It is straightforward documentation with lots of screenshots and easy to follow instructions to get you up and running with a wide range of Cisco products.
Based on what you have asked for (LAN WiFi, Guest Access, and Office Extend) I would check out the following documents:
Enterprise LAN Deployment Guide (Wireless LAN section)
Teleworking Deployment Guide (Cisco OfficeExtend section)
Want some authentication then check out this guide:
LAN and WLAN 802.1X Deployment Guide
And since you bought some pretty sweet 3500s I would recomend that you check out this guide:
Wireless CleanAir Deployment Guide
There are some other guide with more Advanced Guest Wireless as well. If you are a smaller organization then checkout the Midsize docs for doing coresident LAN and Guest on the same controller.
Also we doing a major overhaul on our documents to be release in August so be aware that the format will change a little bit but the archtectire (as always with SBA) will stay the same.
Please let me know if you have any questions or comments about SBA!

Multiple WLANs pointing to same WLC interface

I would like to have a guest Web auth based WLAN that points to an Interface that I also have configured for a separate 802.1X authentication that allows access to my private network. I should note that I already have web auth configured for Guest access that only allows Internet access via separate WALN/VLAN. This would allow me to setup access for a vendor that is on-site using the Lobby Ambassador .
Is this possible and what do I need to do? I have created the seperate WLAN with Web auth and pointed it to the same WLC interface that I use for the 802.1X and this does not seem to work.

This has been resolved. I found I had AP groups setup and had not added the WALN to the correct group.

New WLAN driver advised by Tempro

Tempro have advised of new driver (wlesslan-20091112152038.html ) but there is no comparable reference to help you choose which one to download.
Can anyone guide me to the correct driver to download please.

Then check device manager and there you will see which WLAN card is inside.
Go to Toshiba WLAN portal and there you will find latest driver.
Other way post exact notebook model name and we can check it for you.
BTW: if WLAN work properly you must not change preinstalled driver.

Cannot connect my Satellite A200-1MB to new WLAN router

Hi All,
Recently i bought the LinkSys Router (Model no: WRT120N) and configured it. But it is not connecting to my TOSHIBA laptop (model no: Satellite A200-1MB) with this new router.
It is a wireless connection. I don't think its something to do with the router because the other laptops can access the signal and they can able to connect to that router.
Can anyone please help me out in fixing this?
Thanks & Regards,
Razzaq.

hi rajak.net,
sure all users in this forum are willing to help...
make sure that:
- the same encryption method is used
- the same access key
- the same channel is used
- the ssid is visible
if you cant make a connection turn of *all* encryption and test it
sometimes a update of the ap firmware makes it running...

WLSE, WDS setup need to add new WLAN interface !

This wireless network setup got a WLSE and WDS and lots of Aironet 1210
One SSID with MAC authentocation
Single network I mean the LAN and WLAN on same network
We are in process of seperating WLAN and LAN by means of VLAN and want to retain the old setup for WLAN with a different SSID
Can some one please guide me what is the best approach? I am familiar with IOS can do lot's of stuff with router/Switch and PIX/ASA's but Wireless is not my domain
Thanks in Advance,
Siraj.

You do not need three anten to N
I also have a Sony VAIO laptop and there is a wifi card intel 5100 N (for 300Megabit / s) and plugged the two antennas.
3 if the card has the antenna and the laptop
is needed to 450Megabit / s
which is probably wifi intel 5300 and intel 6300 wifi
For this you need a router 450megabit
This card Advanced Intel Centrino-N 6200
which would use the Toshiba P105-S6024 also has 2 entrances to the antenna. The laptop has two antennas.
The problem lies in the bios toshiba laptop.
Bios adopt certain cards (so-called white list),
I must have deleted the bios white list, or to teach a new wifi card intel 6200
How do I do?
I'm almost 101% sure that the card must match
You have to modify the bios

WLAN and DHCP with WLC controller

Hi,
I've a question about how works dhcp for wifi clients.
On the WLAN edit I've seen that my option are:
1) DHCP override-> i insert the dhcp server address here
2) without DHCP override -> the WLAN will use the DHCP server configured under the management interface
Based upon these informations: why I can configure DHCP server also in other interfaces and not only in the "management" interface ?
If I configure 2 DHCP servers on a "user interface" ( without the "override" option in WLAN ) my clients will use these DHCP or the DHCP on the "management" interface ?
Many thanks in advance
Luigi

from the on-line help it seems different ;-/
=====
DHCP Server (Override)
When selected, you can enter the IP address of your DHCP server. This is a required field for some WLAN configurations. There are three valid configurations:
DHCP Server Override ON, a valid DHCP Server IP address, and DHCP Address Assignment Required: Requires all WLAN clients to obtain an IP address from the DHCP Server.
DHCP Server Override ON, a valid DHCP Server IP address, and DHCP Address Assignment Not Required: Allows all WLAN clients to obtain an IP address from the DHCP Server or use a static IP address.
DHCP Server Override OFF: Forces all WLAN clients to use the DHCP setting in the Management Interface, not the static address.
===========
It seems that i can Use external DHCP server, putting the address :
- in the box that appair when i flag the "override" option
- or in the management interface
I think documentation is not so clean
many thanks
Luigi

New WLAN install

I am looking at installing WLAN to one of our outbuildings at work. I will be putting the transmitter/receiver on building roofs but due to traffic passing the link may lose line-of-sight for short durations (5-10 seconds).
Would this adversely affect WLAN operation?

I can't agree with the two previous comments.
The vehicles passing by are made of metal. They will create reflected signals. You either need to get the antennas higher (plan on about $100 each for mounts that take a vertical pipe), or you need to go to circular polarized antennas.
Circular polarization helps overcome interference created by reflection of the original signal. I can explain why and help you find antennas.
Or, put the stuff in, try it and see if anyone complains.

[new] wlan-config

wlan-config is a perl script that I have been working on for a year or so off and on.
the goal is to make connecting to wireless networks painless, no matter what special things you have to do at each one.
I use it at home to connect to my openvpn vpn on an openbsd machine running pf with a wireless card.
I use it at work to connect to the wlan, then the cisco vpn, then set up the routes, connect to my home vpn and use that as the default gateway.
I use it at school to connect to the wlan and then my home vpn as the default gateway.
I will upload the file into incoming as wlan-config-3.0.1-1.src.tar.gz
There is a difference in the config file so I had to reupload my sourceforge project. It may not be on the mirrors yet.
This package requires perl-config-general which I posted in another post and also uploaded to incoming.
The reason kdebase is a dep is because gwlan-config uses kdialog. I am not sure if i should keep it as a req for the whole package tho, any thoughts?
