Clients connect to wifi with certificate that expires every month - correct way to handle expired certificates?
Hi all
I'm sorry if this is the wrong forum to ask this question. Also my knowledge in this area is somewhat limited, which I why I need your help :-)
We use wireless networks primarily in my company for all our clients and use a certificate to authenticate to the network. This certificate expires after 1 month and we automatically renew them 1 week before expiry. Relatively often we have users that
are not connected to the network for a few weeks or more and then the certificate expires before being renewed. Then we have to connect them to the wired network to get the certificate updated, so they can connect to the wireless network again.
What is the correct approach to solve this issue? We feel extending the life of the certificate would be a too big security compromise. Is there some way you could automatically allow an expired certificate briefly with the sole purpose of renewing the certificate?
Or how would you normally resolve this issue?
Thanks for any help/knowledge you can provide :-)
> Setting the validity period that high, means that the certificate could be cracked before expiry.
then you should be scary of CAs which validity is 10 or more years. And they use the same cryptography as end-entity certificates (key length and signature algorithms). It is a paranoya. Just make sure if client certificates use at least 2048 bit long
keys and use SHA1 (or better) signature algorithm. In this case there is a little chance that certificate will be successfully cracked in 2 years.
If there is an evidence (or indications) of client private key compromise -- immediately revoke the certificate and publish new CRL ASAP. You cannot protect clients from key compromise by using short-living certificates, because key compromise is ususally
achieved by gaining a control over the private key (malware on client computer). Therefore, there is nothing wrong in issuing client certificates with 1 or 2 year validity.

Connecting to wifi with certificate
I recently tried to log in at an free airport hotspot that requires a certificate. I couldn't log in with my Ipad even trying to open Safari. I could log in with my windows laptop, after opening moxilla and agreeing to the terms in the certificate. Can someone tell me how to log in with an Ipad. (I have just found out that it doesn't work with a Kindle touch.)
Nevermind...I found out what the problem was.
For those who are having the same problem. You need to go into Advanced Settings and reenter the User Name under the EAP section. Make sure you check the Manual User Name checkbox also checked. -
Connect to WiFi with certificates
I got old laptop with installed certificate and working wlan and new laptop with company windows image and transfered user profile with windows easy transfer, and after this transfer laptop doesn’t
recognized Office-WLAN but all certificietes installed. But if you move profile with out windows easy transfer all is perfect and wlan working.
What can you propose to fix this problem?Hello,
I'd ask the company IT staff to help you.
otherwise, I'd ask in the Windows 7 IT Pro forums:
http://social.technet.microsoft.com/Forums/windowsserver/en-US/home?category=w7itpro
or, the

I have an Ipad mini with IOS7. A few days ago I began to have problems with wifi connectivity. I can connect to wifi with Google but cannot navigate in Safari nor any of my aps are able to acess wifi. Very strange. Not sure what to do!
Hi ..
Reset the device:
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
If that doesn't help, tap Settings > General > Reset > Reset All Settings
If that doesn't help, tap Settings > General > Reset > Reset Network Settings
You may have to re enter your Wi-Fi password.

If I'm connected in wifi with my Macbook, can I share the internet with Iphone? Thanks
If you are asking about the Internet Sharing feature on the Mac, the answer would be that this option is not available for normal wireless, but it might work for BlueTooth. Might be worth a try that way.
However, if the Mac had an Ethernet Internet connection, then you could create your own "private" wireless network to allow wireless devices to connect. -

IPad 3 with iOS 6 fails to connect to WiFi with WPA2 and AES - any solutions available?
Hello *,
after upgrading my iPad 3 to iOS 6 it constantly fails to connect to WiFi with WPA2 and AES - hidden or broadcasted SSID - at home and at work because the device does not accept the WPA2 password. This is also the case for my iPhone 4S but both devices did work with WiFi (WPA2 / AES) perfectly with previously installed iOS 5.1.1.
I tried to downgrade to iOS 5.1.1 but it seems to be no longer possible to downgrade for both iPad 3 and iPhone 4S as the certification and signage window for iOS 5.1.1 maybe has been closed by Apple.
Does anyone know about a possible solution to connect to WiFi with WPA2 and AES with iPad 3 / iPhone 4S and iOS 6 upgrade?
Thank you very much for any help and advise.
Best regards from Germany

Turn router off then on Try turning your wireless router off then back on.
Change or turn off wireless security You may want to try toggling the settings on your wireless router, switching from WPA to WEP or vice versa, or, as a last resort, turning wireless security off altogether. For AirPort routers, this can be accomplished with the AirPort Admin Utility. For other routers, this can usually be accomplished by accessing the router’s configuration page — open a browser and enter the address 192.168.1.1.
Reset network settings on iPad. On your iPad, open Settings, then navigate to “General” in the left-hand pane. Scroll down and tap Reset, then select “Reset Network Settings.” This will delete any stored WiFi passwords and other information, but may result in a more stable connection.
Adjust brightness upward. Oddly, a number of users have found that they can resolve this issue by simply adjusting the iPad’s brightness level upward and off the lowest setting. To do this, tap Settings, then select “Brightness & Wallpaper” from the left-hand pane. Slide the brightness bar upward, then wait 1-2 minutes and check for an improvement in signal strength. Speculation holds that a power delivery issue associated with the screen brightness affects Wi-Fi.
Change thresholds in router settings. Access your routers configuration screen (for most routers, open a browser and enter the address 192.168.1.1), then change the fragmentation threshold and the CTS/RTS threshold as described here. Some users have found success with the settings Fragmentation= 2048, RTS = 512.
Change 802.11 spec on router. Try changing your router’s wireless spec mode from B, G and N to G only or vice versa. For AirPort routers, this can be accomplished with the AirPort Admin Utility. For other routers, this can usually be accomplished by accessing the router’s configuration page — open a browser and enter the address 192.168.1.1.
Switch routers. Although a far-from-ideal solution, some users have found success with switching to a different wireless router.
Turn off “Ask to Join Networks.” To do so, tap Settings on your iPad, then select “Wi-Fi” from the left-hand pane. Slide “Ask to Join Networks” to off. Speculation holds that leaving this option on causes the iPad to constantly seek networks, resulting in some type of interference with the network to which it is connected.
Forget network then rejoin. Tap Settings on your iPad, then select Wi-Fi from the left-hand pane. Choose the network with which you are experiencing difficulty, then select “Forget this network.” Go back to the previous screen and rejoin the network.
Turn off Bluetooth. Some users report that, perhaps due to interference issues, turning off Bluetooth can boost Wi-Fi signal strength. To do so, tap Settings then tap General in the left-hand pane. Tap Bluetooth in the right-hand pane, then slide to off. -

I used the wrong password to join my new belkin wifi. Now that I have the correct password, I can not get the to the join screen with the space to type in the password. I continue to get the unable to join message. I have put the touch to sleep and I have turned on and off the wifi and join options on the Network screen page. Does anyone know how to get pass this block of the wrong password to a new page that will allow me to type in the correct password. I see there is a option that asks if I want to reset the network settings.. is that what I should do? and what does it erase when I do that? Thanks for any input anyone has.
Yes. Reset network settings. Head to Settings -> General -> Reset and tap Reset Network Settings.

How do i connect to wifi with ipad?
I just recieved my ipad 2. i cannot connect to wifi...help?
Ok so I have been battling with the same issue for a while now and have finally managed to crack it.
I have a Huawei 3G router that has been working for my PC;s and iPhone for a few years now. I then bought an iPad3 (3G and Wifi) and could just not connect it to the wifi network.
Fortunately I have a spare Linksys router (WRT320N) which has a setting to change the Wireless band from 2.4GHz to 5Ghz with 20/40MHz pipe. After changing this no problem iPad could connect.
So now I have 2 wireless networks running with internet connectivity only on the 3G so I plugged a lan cable from the 3G router into the internet port on the Linksys, set the Linksys up with a static internet connection and now I can access the internet via this method on the iPad.
Funny thing is, my iPhone cannot connect to the Linksys my laptop can however. Anyway so now I connect the iPad via the Linksys router and the iPhone via the 3G router.
I think Apple have pretty much messed up with the wireless bands on their products.......it would appear that they don't understand ? If they did they would make it pretty clear and from my efforts to try and sort this out i see there are many people out there, like me, who are laymen and there is no where that this is explained properly.
Most of the installed base of wireless routers I would think are on the 2.5GHz band, I say this beacause there are virtually NO wifi networks out there that I can connect to.
This is a huge frustration and a pretty poor reflection on Apple. So much for MOBILITY!!!!!
