Unable To Get IP Address From DHCP Server?

Sep 4, 2010

I have an enterprise WPA2 PEAP MSCHAPv2 wireless network. It allows access via 802.1x authentication using Radius (MS IAS Server) with certificates. I can join the network, enter credentials (that I can see work) and get the certificate. The problem is that I don't get an IP address. I get a 169. APIPA address. I tried to use a static IP address and that doesn't work either. I have connected various laptops, iPhones even a Dell Streak to this wireless network without issue. My iPad won't get an IP at all. There are plenty of addresses in the pool.The setup is a 3COM WX3008 wireless LAN controller and 9552 access points.Any ideas? I went through the articles on wireless settings and none of them help at all. I guess my next step is to wipe the iPad.Like I said... EVERYTHING else works, every other device we try is surfing just not the iPad.

Wifi Connecting But Not Gettind DHCP Address With Security Turned On

Apr 5, 2010

Wifi works fine if there is no security turned on.it gets a DHCP address and I can happily surf the web.Turn on Security, the iPad talks to the Router and the Router show that it's MAC address is connected, but I can't get a DHCP address and if I do a Static it still doesn't connect.Now I am using an older Router a Linksys BEFW11S4 which only supports B but it works fine with my iBook G4 with Airport Extreme card.I have tried the Reset (Holding the Home and Power buttons for ten seconds until the Apple Icon shows up) and I still get a 169.254.x.x APIPA address.

Unable To Enter Email Address- The Address Breaks In Two Words

Nov 14, 2010

I may have posted this question incorrectly in another section of this forum. If so, please forgive me.

My problem is my email is setup correctly and working. However, Amazon.com requires one to enter the email address. After I enter after the @, my ipad breaks my ISP windstream into two words, wind and stream. Amazon will not accept my address. Can anyone tell me why the ipad uses wind stream in lieu of windstream?

IPad 2 :: Receives But Will Not Send Mail - Recipients Address Rejected By Server

Jun 4, 2014

I know that all the settings are correct as this email address works flawlessly on my Windows desktop and, as I say, the pad does receive mail. The message that I get is that the recipients address is rejected by the server. I have spent a long time on the phone to 1and1 with which company all our domains are registered and they cannot resolve the issue so short of ditching this iPad for something else.

Wi-Fi DHCP Bug Temp Fix

Apr 27, 2010

i have tried this and it does work,go into you wireless router's settings, check your manual for instructions on how to do this.look for the setting that is called "ip address reserve" or something similar. add the MAC address for your ipad to the list and assign a ip address, for example mine is "192.168.1.11". what this will do is assign the ipad the same address every time it connects, this will prevent the DHCP bug from happening. I have yet to experience this issue after doing this.

Wi-Fi DHCP Failure - OS IOS Version 3.2.2

Oct 28, 2010

My iPad's WiFi connection has just stopped working since a couple of days ago. It can connect to WiFi access point. However, it fails to correctly obtain its IP address and other related information such as mask, DNS, and others. So, it shows full bars on the top of screen, but cannot connect to Internet at all. I had used the Internet connection and hasn't changed any network related option at all. It just stopped working. I've even tried to connect to several different wireless access points, but its symptom is same. So, I do not think that it's a specific wireless router problem.I've reset its network setting; furthermore, I've done with "Restore". Even in the original factory setting, it shows me the same symptom. Is it a hardware problem?

iPad WiFi 16GB Other OS iOS version 3.2.2

Switch From DHCP To Static IP?

Dec 2, 2011

Our church school has a small wireless network. I try to support it. For some reason, lately it has stopped giving IP addresses to some machines. Wireless, anyhow. Wired still seems to work OK. Most of the teachers have Windows machines and I install a program called NetSetMan which lets them easily switch from DHCP to a static address I have allocated to them. More a workaround than a solution, but it gets them onto the internet. But now some of them are showing up with iPads. I can go to the settings to give them a static IP, but that means it won't work when they go home (most likely). They kind of glaze over when I try to show them the changes to make. Is there an app which would do for them what NetSetMan does for the Windows machines?

Create A Static IP When Network Uses DHCP

Sep 12, 2010

iPad/Touch connectivity was great until Charter upgraded our router to an SMCd3gn yesterday. We like what the router does for all our other Macs but the mobiles are not happy. I've read about the glories of giving them a static IP but I can't figure out how to do it when our network is DHCP. Do I use the IP address currently assigned on the DHCP screen? The other thing is that we have to use OpenDNS numbers on all the computers or the router is extremely slow, unlike the old one so it's definitely the router. Does this complicate things? If I can make the iPad static could someone tell me what goes where? Surprisingly, this is not yet on the web.

Periodic Loss Of Connection - DHCP Client

Apr 28, 2010

Symptom: signal not weak, but iPad periodically becomes "not connected"

Workaround: go to settings, find the network, and connect to it.

Note: password is not being forgotten in this case.I think my iPad is having problems when it's DHCP lease expires. It does not appear to be renewing its lease gracefully. Instead it winds up disconnected. The DHCP lease expiration is a theory, but it seems to fit. I noticed that disconnections happen about once per day, which corresponds to the 24 hour client lease time as set on my router. Checking the router's lease table, I also saw that several devices were renewing at about the same time, which perhaps also contributes to the problem. Potentially, there could be a brief conflict when this happens When there is an IP conflict, most other devices will just request a new lease. But I figured I could prevent this by manually renewing the iPads lease so that it would have a new renew cycle.

Unable To Use Map App - Cannot Connect To Server

Aug 31, 2010

Is it just me? The iPad Maps app won't let me scroll, search or zoom. I get an error that says I cannot connect to the server, or I get a "server error". I can go to Google Maps via Safari and it works just fine. Is this a 3G only application? All other connectivity works. It's also weird that so many areas have no detail on the iPad's Safari look at Google Maps, when the same locations have full terrain and close-up views on my computer.

Unable To Get Rid Of 'Can't Verify Server ID'

Apr 24, 2011

I get the message "Cannot Verify Server Identity. Wi-Fi can't verify the identity of '1.1.1.1'. Would you like to continue anyway?" It then gives me the choices "Cancel," "Details," and "Continue." But when I press any one of these nothing happens. I can't get rid of the screen. The slider doesn't work and using the iPad power off button doesn't resolve the issue.

The problem first arose after I went through the X-ray machine at an airport. At the time, I did not have the Airplane wireless off function activated, if that makes a difference. I am now at my destination (I am overseas) but the problem persists so it is not location-specific.
