Wifi has limited connectivity

I have posted issues several times now without ever getting any answers. So here is the third attempt.
WEP security, while not reliable at all due to the use of PSK, is required for bridging multiple AP's into a the central router. The passkey is passed into the PSK encryption routine and to create a minor level of protection, the encryption populates one of 4 keys. In windows when I connect to a WEP network the login screen provides the passkey and a field for identifying which key is being used.
ISSUE: iPad login asks only for the passkey and NOT the key number. This is a bug and it seems the only way to get around this is to configure the router for key 1. Regardless this is a bug as the process should request which key to use.
I reconfigured my network removing the bridging, implemented WPA2-PSK with AES encryption to return the network to a secure state. However my iPad would not connect to the network. It looked like it was going to connect (long delay) and then reports it failed to connect. I used notes to create the passkey to ensure it was entered correctly. So far I've not gotten any answer as to why the iPad cannot connect using this security.
I reconfigured my network once again to use WPA/WPA2-PSK mixed and now I can finally connect the iPad to the network with the passkey. But when I go back it fails to join. Does the iPad handle AES encryption?
I'd really like answers to these questions as we are evaluating using the iPad as a key part of our architecture deployed at multiple customer locations internationally.

If you feel that there is a bug in the processing of WEP you can communicate this to Apple at http://www.apple.com/feedback/ipad.html. You should note, however, that WEP security is obsolete and insecure (it can be cracked in seconds with widely available software). WEP should not be part of any commercially deployed product.
The iPad does handle AES encryption. I and many others are using it without problems. Despite your precautions the password you entered was probably incorrect or you were having other network/router configuration problems.
It is difficult to comment on the reconnection problem you are apparently having without knowing more about the sort of network you have, type of equipment, configuration, testing procedures, etc.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.

Lenovo G505 Wifi Problems - Limited Connection, No Connection, and Dropped Connections

Some forum members have reported a variety of Wifi issues with their G505 laptops. Their reports range from showing "Connection is limited", to Wifi connections dropping repeatedly, to being unable to make a Wifi connection at all. I combined multiple threads in order to assist forum members with troubleshooting solutions.
If your G505 was upgraded to Windows 8.0 or 8.1 and then lost connectivity, or you recently purchased a G505 running Windows 8.0 or 8.1 and are unable to connect, try following the instructions posted by Vikramsbox to restore the connection through the Lenovo Communications Utility.
For non-Windows 8.0 or 8.1 users, start troubleshooting with the basics:
The most recent WLAN, BIOS, and Power Management drivers from Lenovo can be downloaded here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-g-series-laptops/lenovo-g505-no...
It is also good practice to verify your Wifi is activated by following the instructions from Neokenchi.
Check Power Management settings to ensure your laptop isn't turning off the Wifi as noted by Dannyk1.
Check to see that Airplane Mode is set to OFF by following the instructions provided by Shiv_K.
After trying those steps, if you still experience a Wifi issue with your G505, other troubleshooting steps have been noted in this thread. This includes a whitelist of accepted replacement WLAN cards posted by Topmahof and a 3rd party driver which resolved wifi issues for Miila and Jessemck125. Please note that while Lenovo does not support 3rd part drivers, it may be an option to consider if your laptop is out of warranty and none of the suggestions in the thread resolve the issue.

First computer was a 1980 Commodore 64 from Radio Shack/ GEnie SFRT member from 1993-1996

First is to update your Atheros/Broadcom driver for your G505 here:http://download.lenovo.com/consumer/mobiles/wlan117w8.exe
From what I understand, the situation is that you get limited connectivity while your other devices that are connected to the router gets uninterrupted internet access.
After updating your drivers, you can try to flush your DNS cache by copy and pasting this code to your notepad and saving it as FlushDNS.bat
@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0
Note that this will restart your computer so make sure to save your session first.
Here's the link that explains the benefit of flushing DNS: http://www.sevenforums.com/network-sharing/144365-network-posting-tips.html

Hyper-V vSwitch on a NIC-Team (Server 2012 R2) has limited connectivity

Hi,
I have two servers both running Server 2012 R2. One of these servers is serving as a DC and is working fine. The other is supposed to be a Hyper-V-Host, but I cannot get networking working on this system. Both systems have Hyper-V role installed. Both have
2 NICs configured as a team. The team is configured as switch-independent, Hyper-V-Port, None (all adapters active). A Hyper-V-Switch using this team as external network is configured and is shared with the host operating system. This should work fine and
does on one of the servers. On the other I get a warning sign stating limited connectivity. The server seems to sent packages but it receives none. Deleting the switch and simply using the team for network access works fine. So it has to be related to the
switch. But I do not know what's wrong with it. Any ideas?
Regards,
Oliver

Hi ogerlach_isw,
Generally please don’t install others role on Hyper-V server, if your DC using NIC teaming, please break the teaming then monitor this issue again.

PC (XP) etherneted to IMac has limited connectivity

My PC(XP) uses the Imac for its Internet connection via an ethernet cable. The Imac is connected to a house wireless system. Suddenly the PC has a "limited or no connectivity" issue. I can see the contents of the PC by using the Imac finder, so that is at least telling me the card and cable are fine (more or less). To connect the two I used "Ethernet", location "Automatic" and then "Configure IPv4"-"Using DHCP with manual adress" under the IMac system network prefs. I had a number under the DNS server but don't remember what it was. On the PC I had automatic IP configure with the DNS inserted manually, the number which I don't have. When I go to "repair" the network connection on the PC I get an error message saying that it can't "renew my IP adress". This problem just popped up suddenly as there were no hardware or software changes on either machine. Hope someone can help :-)

The problem you are having probably lies with the encryption key.
One of the problems with WEP is that the actual standard relies on a 10 character HEX key for 40bit WEP and a 26 character HEX key for 128bit WEP.
In order to make things easier for people, vendors use certain algorithms to convert simple alphanumeric passwords (or passphrases) into HEX keys, thus enabling people to use simple memorable WEP password rather than lengthy HEX keys.
The problem is that different vendors use different algorithms to generate the HEX key and therefore a ASCII password on an AEBS will be hashed differently on a Netgear client and vice versa.
One thing is a 13 character 128 bit WEP password will be hashed by all vendors in the same way (if you use 40bit WEP then a 5 character password is required).
Though sometimes not even that works and the HEX key must be used regardless.

XP laptop now has "limited connectivity"

I have an airport extreme, a mac mini, a macbook, and a toshiba using XP all working just fine on my wireless network. However, my HP laptop also using XP cannot connect any more to my network, I get excellent signal strength but limited or no connectivity. The IP address was showing as 169.xxx instead of the 10.0 xxx it should have been, now it is blank. Any suggestions?

Dear apple, I am really dissapointed with you. Around January 2013, my iPhone 4s 16GB White has hardware issues, which was the Wi-Fi grey out. The wifi grey out means that I can't access the wifi on/off button, and also it has no connection. I have put up

Dear apple, I am really dissapointed with you. Around January 2013, my iPhone 4s 16GB White has hardware issues, which was the Wi-Fi grey out. The wifi grey out means that I can't access the wifi on/off button, and also it has no connection. I have put up with it for months, until june 7 when I decided it has been long enough, and I got a replacement. I told the genius bar what happened, and I already did the so called "steps" that apple reccommended on the site, which was reset network settings, restore iPhone. The genius bar gave me a replacement phone, so I was expecting that the problem would be over, but it isn't. It seems that it's iOS 6.1.3 which is the case of most public complaints on apple iPhone products. Not even 3 weeks after I got the phone replaced, it is doing it again, so I suspect I'm just going to get a replacement again? Unfortunately I only have until 5th of july 2013 until my 1 year warranty is up. After that, any issue I have, I have to purchase apple care. People are expecting this problem to be fixed but I don't see it being solved any time soon. This is horrible and really low, because I have been a good customer, when I talk to the people at the genius bar, I show the utmost respect I can to them for the work they put into their job, but somewhere there is a problem where something has gone wrong. Because of that, people that only have a one year warranty (which i received because I purchased my apple iPhone at an Optus outlet, once that one year warranty is up, I have to pay for a problem that isn't even my fault? That isn't how it should work, you should be fixing this problem so people can be happy customers and leave happy. Obviously you don't all know how to do your jobs, because if you did, we wouldn't have this problem. I would like a replacement phone, ONCE AGAIN. If this problem occurs again, I will simply stop buying your products, and lose faith in your company, your's sincerely, Jack Maher.

This is a user to user help forum only. You are not addressing Apple here.
My iPhone 4S, iPhone 5, and iPad 2 are running 6.1.3 with no such problem and the same with the overwhelming majority of iOS devices running 6.1.3.

I have an Ipad 2. My wife has an Ipad mini. When we connect to Itunes it installs all the apps from one Ipad on to the other. I unchecked the box to automatically update apps, but Itunes still does so. How do I prevent Itunes from intalling apps?

I have an Ipad 2. My wife has an Ipad mini. When we plug in to Itunes (at different times) it synchs the apps from one Ipad on to the other. We don't want this. I have uncheked the box for Automatically synch apps, but it still does this.
How do I get Itues to see each Ipad as a separate item, and not try to keep them "equal" as far as apps installed?

Remove the apps from iTunes with your device connected. You can basically deselect the apps that you don't want on each device. We have three IOS devices on one AppleID and they don't all have the same apps.

The wifi has been lost or disconnected on my iPad. It's the iPad 2 and has not been updated yet. It's IOS 6.1.3 .. how do I add a network back onto it? I have typed in the name and chosen each of the securities and still hasn't connected!

Hey there Luba_kalstad,
It sounds like you are unable to join your network and cannot see it in the Wi-Fi list in Settings. I would try the troubleshooting outlined in this article named:
iOS: Troubleshooting Wi-Fi networks and connections
http://support.apple.com/kb/ts1398
Be sure you're in range of your Wi-Fi router (access point).
Tap Settings > Wi-Fi and turn Wi-Fi off and on. If your Wi-Fi setting is dimmed, follow these steps.
Confirm that your Wi-Fi router and cable or DSL modem are connected to power, turned on, and connected to the Internet. If not, refer to your network administrator or Internet service provider (ISP) for assistance.
Restart your iOS device.
Tap Settings > Wi-Fi and locate the Wi-Fi network to which you're connected.
Tap and Forget this Network.
Try to connect to your desired Wi-Fi network.
Note: You may need to enter your Wi-Fi password again if your network requires one.
Turn your Wi-Fi router off and on2. If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
Update your device to the latest version of software.
Update your Wi-Fi router to the latest firmware2. For AirPort Base Stations, install updates using the AirPort Utility.
And this section down toward the bottom if needed:
Unable to locate a Wi-Fi network
Verify that the network is available by tapping Settings > Wi-Fi and choosing from the available networks.Note: It may take a few seconds for the Wi-Fi network name to appear.
Move closer to your wireless router (access point) and attempt to locate the Wi-Fi network.
If you do not see the network you would like to join, you may be attempting to connect to a hidden network. Learn how to join a hidden network.
Supported Wi-Fi configurations vary by iOS device model. Find out which standards your device supports3.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including:
previously connected Wi-Fi networks and passwords
recently used Bluetooth accessories
VPN and APN settings
Thank you for using Apple Support Communities.
Take care,
Sterling

My wife has just had a new iPad and while Wifi works fine with it at home, at work it will not connect to the Wifi despite the correct password being entered. The 'waiting wheel' simply goes round and round next to the Wifi network attempting connection.

My wife has just had a new iPad and while the Wifi works fine at home, at work she is unable to connect after entering the correct password etc. The 'waiting wheel' simply spins next to the network attempting to connect. The iPad version is 5.1.1 and not the IOS 6 which seems to be problematic on the Wifi front. To add to the mystery my own iPad connects fine to my wife's place of work. Is it possible to take the manual settings from mine and connect that way? Or any other suggestions?

When your device is trying to connect to the work Wi-Fi network, go to Settings > Wi-Fi > then tap on the name of the Netowrk that she is having trouble with. Then tap on forget this network. Let the device attempt to connect again and make absolutely sure she is trying to connect to the work network and not a nearby network, then make absolutely sure the password is entered correctly.

When i connect my iphone to my imac, itunes opens but my itunes is not there. My wife has recently added herself to the computer
and her itunes appears but i cannot find my itunes?

Not really! Anyhow, what do you want to achieve. The only things you can access in your iPad outside of using iTunes are photos and videos. [Locate the iPad as any other external device through Windows Eplorer or Finder and dig through the folders.]
You are fortunate that iTunes opens when you connect the iPad since many other users have difficulty in achieving this. It is from there that you can manage what you want synced to the iPad.

HT4623 Since updating to iOS6 my wifi has not been able to connect properly

Since updating to iOS6 my wifi has not been able to connect properly. Has this been a problem for anyone else?

i have a iphone 4 and had a similar problem with the upgrade, I went into settings,general,cellular,and turned off icloud documents,passbook updates and reading list and it corrected my problems

HT4199 My iphone has always connected automatically without problem to the wifi network at work, i.e.BTBusinessHub, and at home, i.e.Bthomehub. Now it tries to connect at work but doesnt manage it although it still works at home. Can anyone advise why?

My iphone has always connected automatically and without problem to the wifi at work i.e. BTBusinesshub and at home BTHomehub but yesterday it would not connect at work. It is ok at home but again today at work it is not connecting. It appears to try but is not connecting, please help.

You can try doing a reset, hold down the home/power button until you see the apple logo and then release, then wait for the phone to boot back up - then check wifi - if that doesn't work then
do a network reset note: you will have to reenter wifi password again when your in range.
settings - general - reset - reset network settings. If that doesn't work then I would talk to your IT dept.
