I have a ZyXEL P-2602HW-D1A Wireless router. I have tried all combinations of security, even NO SECURITY WHATSOEVER, and still the device won't transfer data.
Not working;
Firmware: 1.5, Build: CR817
Wifi Router: ZyXEL P-2602HW-D1A
Security: Tried All; WPA2, WPA, WEP & None.
Problem: Connect under all conditions but no data is sent
Please help.
Have you tried another WiFi access point to check the devices WiFi module actually functions?
No, I haven't tried that yet, but don't really see the point... I've connected effortlessly to the same WiFi network with my HTC Touch Diamond.

For some reason my N800 wouldn't connect to MY ZyXEL P-2602HW-D1A unless I set the device (N800) to disable any kind of wifi powersaving features it had.
On another note, how did you get your hands on the device so early? I'm guessing you are using a Cybercity internet connection? (I'm in copenhagen myself)
edit: I actually came to that solution when i noticed I could connect to OTHER accespoints, but not the Zyxel ones.
Same problem here in France with a Freebox as router
I've noticed under the router's WLAN client list that the device does not have a "Host Name". Would that present a problem?
It is assigned an IP address by the router without any problems, though.
Also the device seems to lose connection and reconnect constantly (every 5-10 seconds).
I done some digging around in the router settings and found an "AnyIP" feature. Would that possibly help?
There are a number of issues floating around. Support for WPA2 seems iffy and some people can just change to WPA or WEP and all work fine.
There are however a number of people (such as me) who can get a connection perfectly, it shows connection OK, they get an IP from the DHCP server etc, they can even browse a page for a few seconds... but after that no data is sent and everything times out. This is happening on any security from none through to WPA2.
I have seen no solution to this anywhere and believe me I have looked. Some people have given up and got a new router, but this is not a solution.
Can someone confirm that this has been recognised as a fault with the magic and is being investigated, rather then assuming it's a user or router error. There are far too many instances of this across many brands of router for it not to be an issue with the HTC Magic.

What I mean is have you tested the device on ANY other AP except the ZyXEL?
No, but since I'm by far the only one having this issue (try searching the web; see my last post), I didn't feel it was necessary. Just want some input from xda-dev that might solve the problem, if any.

I've had exactly the same problem earlier with the N800 on the zyxel. Exactly how you describe it.
Did you find out if you could turn off any powersaving features on the HTC?
same problem here
in france with a freebox
I don't exaclty know what router is in the box
but I have excalty the same
I set on never the wifi sleep(powersaving) mode.
i found it in setting wifi menu button then advanced and "never"
but the problem is still here

I have the exact same problem on mine. I just hope it is not a hardware issue...
Could be DHCP lease time problem. Did anyone of you tried to set up Magic with Static IP?
Yes, I tried that also - didn't help one bit.

I also have this problem. Im in Denmark with a Zyxel P660HW-p1.
Another user of Cybercity in Denmark with the same problem.
ZyXEL P-660HW-D1
The android is the only device that doesn't work. I have tried with Iphone and laptops.
I've tried to change the settings on the router to no avail.
Enable 802.11g+ mode [on/off]
RTS/CTS Threshold [2432/4096]
RTS/CTS Threshold [2432/4096]
Max. Frame Burst [600/1800]
The device shows up in the device list with no hostname, the HTC Magic gets the right ip address (using the program WhatIsMyIp to view it)
I had the same problem before, when I set my TP-LINK draft N router with WEP security my HD can see it, connect to it (but speed was slow tho), and my HTC Magic just keep saying its not in range. However, when I set it to open security it works, so I recognise its probably the security setting... so I changed that to WPA2 and then it works.
In my case, I see different device have different tolerance to some settings (in my case, draft N + WEP is OK with laptop, HTC HD, but not Magic), so its still worthwhile to try a few different settings, and try a public wireless access point also to double confirm?
Power save?
I have Zyxel (P-2602R-D1A) router.
I had exactly the same problem with my HTC Vox (winmo)... but that was solved by boosting the WiFi in the phone.
WiFi -> Best performance
So Im guessing magic is in some WiFi "power save" mode...
I dont know how this works, but I thought maybe you could change some WiFi settings behind the hood - that is if the hardware is capable of it.
Zyxel (P-2602R-D1A) router
I am having the same issue with this router as the other posters. The phone connects perfectly and reports an excellent signal, but barely sends or receives any data. I have used a terminal emulator to ping the router and it reports an 82% packet loss. This must be a big problem for many Danish users as it is the standard wifi router provided by two of the major ISP's.
same issue here with my vodafone uk magic.
wifi connects and i can browse for a few seconds then get a connection error and can't browse until i re-start wifi on the magic...
i've actually given up using wifi at home now due to this.
router is a talktalk supplied Huawei Echolife HG520b using 128 bit WEP
i can connect fine via wifi at the office so i don't think it's an issue with the handset, just with certain routers or router configs...
this issue has been reported on the vodafone uk forums but as yet no solution.

Honestly I have no idea why this is happening on my android 4.0+ devices. I will get stuck on obtaining IP address connecting to certain networks and the only thing that worked for my home network is static IP. But for instances when I don't have access to the router to know what the static IP should be, is there a way to get this working? This happened on my phone as well. I was at a local cafe which had wifi and before I upgraded my samsung galaxy s2 to ICS, I could connect to their wifi no problem, now it has the same issue, and so does my Nexus 7. I don't know what to enter for static IP, I entered some random IP, it connected but internet still didn't work. Why is this problem plaguing ICS onward, and does anyone have a workaround when static IP is not an option?
This is definitely not a universal problem (I've never heard of it before). Are you running stock roms? If not, then do you have these problems with stock roms?
C2Q
Why are you posting this to multiple threads?
There is no "proper way" to use a static IP for a router that is setup for DHCP only. For routers that use both, many times the static IP's are reserved for specific devices.
Sent from my Nexus 7
Because I didn't notice the other thread before I posted this one. Anyway then why is this obtaining IP address loop a problem on ICS? As I said, my phone on GB would manage to connect/obtain an IP address just fine before I upgraded to ICS. This happened with my home router and other areas as well. The solution that worked for me at home was to assign a random static IP within my routers IP range. But if I don't know the gateway IP this won't work. So what gives? I'm kind of confused what you mean by routers set up for DCHP only. If I use static or DCHP options on the android device to connect, they will both work (this was before ICS).
I ran into similar issues with my nexus 7 and my work open wifi. It needs you to connect to a web login page where you accept a use policy before you can surf. My nexus would connect but never redirect to that login page.
The issue was resolved by using static IP instead of DHCP and also by changing the DNS values to DNS1 8.8.8.8 and DNS2 4.4.8.8
Changing those settings lets me finally use my work wifi. My phone also has the same issue (its an ICS phone, whilst the nexus is jelly bean) but is not resolved with this change.

Sure that is not 8.8.4.4 ?
Thanks for posting this question. I have exactly the same problem with my Samsung S3 (ICS) and Nexus 7 (Jellybean). My old Samsung S2 (Gingerbread) worked fine.
I am trying to connect to a hotel open network. When I try I get the looping "Obtaining IP..." message. I have a strong network signal.
What gives? How come earlier versions of Android worked but later ones don't?
As the OP stated, the static option works insofar as I can then connect to the network but the made up static IP numbers do not actually let me download (or upload) data. As the OP wrote, you need to know some valid values for the static IP setting.
Does anyone have a solution for this (apart from downgrading to Gingerbread)?
Ive always had this issue but my home router has dhcp off. A majority of routers start with 192.168.1.1 or 192.168.1.2 so its not hard to work it out.
BT routers always start with 192.168.1.254 so there's another option dunno why my devices do it but im used to it. My Wifes Xoom 2 and wildfire S are stock and do not have the issues my rooted ones do but i have just put it down to coincidence
First off. Is your modem in service? Do other devices connect? Have your restarted your tab? Does it connect to other networks? Meaning going to another WiFi hotspot If you can answer yes to all of these questions we move on....
What modem/router are you connecting to?
What type of WiFi encryption are you using? Wep-open, WPA, wpa2-psk
On the tab does it fail to obtain the IP address? Meaning it says "remembered"?
Not going to lie more the 3/4ths of the time you have the wrong WIFI PASSWORD. CHECK IT AGAIN usually its on the modem/router or if you have no clue here is a hint: on windows vista and windows 7 under control panel>network and sharing center>manage WiFi networks if your right click on the network name such as "Ilovepancakes"and go to properties it will have a security tab that you can click on and show password.

I don't know what you mean. Do you mean that I should try these numbers to see if they work? You need a number of values to set up static IP addressing to work.
Did you dirty-flash your Nexus? A while back my Gnex wifi connections would take longer to complete the handshake. I did a factory reset/fresh install & it has been much faster.

My Nexus (and GS3) is completely stock (I have only added a launcher).
This problem seems to be caused by older routers, which don't seem to like something about newer versions of Android.
I'm not sure if it's something Google can fix, but the combination of old router and new Android seems to make logging onto wi-fi networks a problem.
Bump.
Ive been struggling with this problem for a week now since getting a transformer infinity. My s3 gets stuck when I try to connect to it. The tab cycles through connecting, obtain a valid address and saved.
I bought a new 32gb nexus yday and had this issue. I entered advanced settings, changed dhcp to static. Changed IP addy to 192.168.1.1 and it worked fine. Only had to do it once. After that it connected to every network fine without changing settings again.

This worked for me also (Infuse 4G on JB), but it seems like this is only a problem on WiFi AP's that have marginal signal strength, even though they appear to have full bars. I personally have never have seen this issue on a network that was performing properly.
Same here!
Same thing is happening to me! Im using he htc desire c running ics.. my phone detects the wifi network, shows that it has excellent strength, but it gets stuck at "Obtaining IP Address"! My friend and I both bought the same model a couple of weeks earlier and till now neither of us have been able to connect to a wifi network! Please Help!!!
its a DHCP bug
This is probably not a problem with your network configuration unless it works everywhere else; im having the same problem as well as other people i know and its definitely a bug with DHCP, so the only way to work around this is by using a static ip as far as i know

What he's saying is that most routers will begin assigning addresses starting with 192.168.1.1 or 192.168.2.1 for itself (you can access the router configuration page by typing in this address into a web browser), and then increment upwards afterwards. If you knew that the router started its DHCP addressing with 192.168.1.1, for example, you could try 192.168.1.2, and so on and soforth.
If you did a "dirty" upgrade, I'd recommend doing a factory wipe (after an appropriate backup-- there are some good apps out there that can handle this). In-place OS upgrades have a bad habit of being finicky. Android is also generally less tolerant of network "misconfigurations" than, say, Windows, OS X, or iOS. Many networks that use captive portals (your standard coffeeshop Wi-Fi) deliberately use an altered network setup to support their access policies, such as a captive portal.
However, with the exception of corporate/enterprise networks (which may require fine-tuning because of increased security), you really shouldn't be messing around with this if you don't have at least a rudimentary understanding of how networking works. That's not meant to be insulting, but when people plug in random values and find it doesn't work, it tends to lead to more frustration than utility.
(fyi: The reason you can "connect" by tossing in a random set of octets your your IP and DNS is because you've properly authenticated against your router, but you'll never be able to receive data unless your router's DHCP lease lines up with your self-assigned IP, because the router never handed that address out to you. It's the digital equivalent of building a mailbox in front of your house without registering with the post office, and wondering why you never get mail).
There appears to be a problem with new versions of Android and old routers. Many people have reported the "obtaining IP address" loop problem.
Let me explain. I use the leisure facilities in a local hotel. It has a public (open) wifi network. I believe it uses an old router. My Galaxy S2 (Gingerbread) and AsusTransformer (ICS) both connected to this network without problems. I recently replaced the S2 with an S3 (ICS) and my Transformer with a Nexus 7 (Jellybean). Neither of my new devices connect to this network. I have had the same problem in a local cafe.
I have researched this problem. It is not uncommon. It appears to be caused by an odd mix of hardware (router and wifi chipset) and software (later versions of Android). If you are unlucky (like me and some others) you will be unable to connect to some networks.
The solution is to use static IP addressing (since your device is unable to obtain a dynamic IP address). This will allow your device to connect to the network -- but you need to know the correct settings (for static IP addressing) before you can actually use the network.
This problem has been reported by many people. Does anyone know if there is a fix or a workaround?
The only one I can think of it to get hold of a device that does connect to this network and copy the (static IP) settings. But this would only solve it for one location meaning that I will run into it again the next time I try to connect to a network with old hardware.
Sometimes when I get that problem it's due to IP address conflicts on the Windows 7 computers.
I go to the computer and:
http://helpdeskgeek.com/networking/release-and-renew-an-ip-address/
Otherwise I just pull the router out and refresh it, should work for another few weeks or so.

I don't have access to the PC. It is owned by the hotel. I need a solution that I can apply client (Nexus) side.
Solution
I found a solution. I asked the guy to reset the router and both my Nexus and S3 immediately connected. Someone advised me to do this. I have no idea why it worked. Not really a solution since i cant go round cafes asking people to reset their routers for me.
Is there a way to find out IP, DNS, gateway etc values on Nexus when they are dynamically assigned?
I sometimes have this Problem when starting my accesspoint after enabeling wifi on my N7.
I have to reboot my N7 in that case to get an IP.
Happened to me quite a few times when I went out with it to a restaurant or something. It just loops and loops.
My Nexus (and S3) now connect to the hotel network every time now. So it looks like you only need to ask the owned to reset his router once.

Resetting the modem solves the problem if you don't make any change to the router settings. I don't understand why the hell google is not solving the problem yet...
many users are found to face the same problem..
eve I can connect with my Nokia E72 but not with my N7...
I can get the IP from my cell phone. But come on, what's the point of doing so?? Are you gonna assign the IP for each and every WiFi you connect?? Or if the IP changes everyday??
Static ip won't help, yes you can connect to wifi, but cannot get connection to internet. This is a bug of android, and ITs in Princeton univ. had some investigation. 412 should have fixed it

I just started having a similar problem. I have a samsung galaxy tab with Sprint. I've had it for a year and this is the first time I've had this trouble.
The only difference is, I cannot connect to any wifi network at all. It keeps hanging on "obtaining IP address" and then disconnects. It doesn't matter if it's my home wifi or school or free wifi in a restaurant.
The only possible connection I can make is that I downloaded Lookout to check it out as a possible security app, I have since uninstalled it but that did not fix my problem.
Continuing to research this but any ideas on how to fix this would be fantastic.
I'm having this problem on my HTC One S. It happened yesterday without warning and it's really annoying. I went to a nearby cafe and the wifi worked perfectly, so it's something wrong here.
Static IP solution connects to me to the network but I can't actually use the internet, so I'm stumped.
i'm getting the same error with AOKP 4.2.2, and also know people with stock 4.2.2 with it.
the only way i found to fix it is to reboot the phone..... and wait for it to happen again and reboot it again
i cannot use static IP since in my university (and some other public places) it is not possible to connect it like that :S

WiFi connects to my router and stays connected at excellent signal strength without any trouble. Internet connection however, always disappears after a minute or so. Then my Dolphin Browser either keeps loading a website forever or gives me some error like "Webpage not available". Same story with stock or any other browser. I'm not sure since how long I have had this issue. It surely existed already when my phone came back from warranty service (and I had sent it there because of very short range of WiFi commonly known problem which they fixed by giving the phone new hardware). I think that upgrade to Android 4.2.2 might have caused my problem, but it was such a long time ago that I don't remember now (I don't use/need WiFi that much, mobile data internet is enough for me).
What I've tried so far:
-rebooting phone and router obviously
-factory formatting the phone
-WiFi analyzer app
-changing all the network parameters and re-setting it up
-WPS connecting
-playing with all the WiFi settings on my phone (proxy settings, ip settings, wifi optimization and other)
-finally, today I unlocked bootloader, rooted and installed custom ROM hoping it'd help (but it didn't and now I lost my warranty lol)
What I have:
HTC One X Endeavor
Android 4.2.2 HTC Sense 5.0
Android Revolution HD 33.1
3.1.10-g7f360be Kernel version
TP-LINK
N750 Wireless Dual Band Gigabit Router

I'm thinking about installing other ROM, some that works on Android 4.0 or KitKat, could it help?
Oh, and I should add that two different notebooks, Galaxy S4, S3 mini, Xperia X10 and a tablet all work fine with this network :>
I can provide any screenshots, photos, names of devices etc., just tell me what is needed.
HELP!
I have a similar problem with my device, but I just reset my router and it's fine. Maybe your problem is that your phone doesn't receive an ip address. You can check out if you have received an address via settings->wi-fi-> advanced, and check the 'ip address'. If it says ' not available, reset your router and your phone's wi-fi until you get one.

Hm…it may be a hardware problem.
Hi, i have my Samsung Note 4 phone and O.S. ver. 5.1.1 stock firmware, no root and build N910FXXU1COH4.
I've noticed problems on Google Search, Facebook and upgrading on Play Store when I'm connected to some wifi network.
Recently I configurated at my friend a station to receive Internet connection (Adsl) from his brother and I installed him a TpLink Cpe and an access point with ddwrt software installed.
Then...my Note 4 has the problems I said and pc, Samsung S3 Neo and another Samsung work regurarly for all apps, upgradings and searchings!
I don't know why I have this issue in my Note 4!
I configurated the Cpe setting as dns (not obbligatory) the ip of his brother's router connected to internet.
I tried to insert 8.8.4.4 with static ip but I don't fix the issue.
P.e.: i noticed that the issue is caused by upload that is about 0 Kb/s and others devices don't have this issue.
Do you know why?
I also upgraded my stock firmware to COJ3 but i haven't solved the issue...[emoji53]

From what I can understand there is an issue with Lollipop where if it sees IPv6 on your network it will always try to do DNS over IPv6, even if its not actually functional. As such, DNS completely breaks when using IPv6 capable routers (guaranteed if you run DD-WRT, OpenWRT, pfSense, etc) if you do not have IPv6 support enabled on your Internet connection.
I ran into this myself recently as I was trying to disable IPv6 on my network as it was not fully functional, but it completely broke connectivity on my Note 4.
The March security update seems to have made this worse, as even after restoring partial IPv6 I can now do DNS but actual connectivity still fails instead of falling back to IPv4 like its supposed to.

Thank you my friend. I read only now your message..
I don't know if we have the same problem.
Now my phone is going with the latest MM stock firmware and I have always the same problem..
Some other phones work good except someone..
I don't know if it's a issue about IPv6 but I can ensure you that I linked all phones in same way to wifi but their behaviour is absolutely different related those apps..
