WiFi data transfer problem

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.

Wifi - getting address, no connection at the end

Hi, in case this has been already solved I apologize in advance, however I searched all the post on this and could't find real solution to my problem and from what I have read I am not alone...
The think is that if I install any build of Androud to my Leo everything works perfect except the WiFi connection - after enabling WiFi and pointing it to my router it recognizes it, accepts the password (WPA-PSK protection) and then after some time of getting IP it never connects and it goes on and on.
I tried every single thing I have found all around this forum and many others, unfortunatelly nothing could make it work (forcing static IP, opening the network without protection, changing networks SSID, leaving WiFi on and restarting, etc.)
It is really pitty as I really like the way Androind moves on HD2, but as I use the Wifi a lot to unload a bit my data plan I cannot stick with it at the moment. So, is there any real solution to this problem?
Thank you in advance.

I have the same problem. But the connection is fine when I was under Winmo.

The only time I've experienced a similar issue was when I upgraded to a new kernel, without pushing the new modules. What builds and kernel are you using?
Sincerely,
Mac

Try updating your builds or just modifying the mac adresses

I already have this issue when upgrading or changing build. I resolved the problem with Airplane Mode. switch on/switch off. Let us know the result. ^^

I was having the same problem. It wouldnt connect to my home network, but it would connect to every other network. Turns out my router was too old. I recently got a new router and it works fine. Also, when I had my G1, it also wouldnt connect to my home network via wifi, but it does with the new router.

As I wrote before, I tried many different builds with no succes. At the moment I installed MCCM SE V3.4(FroyoStone Sense)[kernel hastarin r8.5]. As I have nothing to save I do everytime clean install on reformated card.

IMHO the router is not the problem even it's a bit outdated - Linksys WRT54GL - as I tried to connect to friend's network, I also created AP from my notebook - with the same result.

The Airplane mode you toggle in WinMo or Android? I tried it in WinMo - no success.

oh yes...
... I know this kind of problem.
Tried so many builds of Froyo. Most wlan-stable was indeed MCCM SE V3.4(FroyoStone Sense)[kernel hastarin r8.5] - with this build I had no wifi drops or hsdpa drops.
From today on I try the MDJ FroYo HD v.4.1[kernel:MDJ S7.3HD]. Most time it holds the connection, but sometimes when waking up from stand-by I have to disconnect and reconnect wifi.
Router: Linksys WRT54G.

Thanks for the answer, unfortunatelly I have nothing to drop as I cannot connect. On the other hand either EDGE and HSDPA works like charm - solid connection.

Into Android my friend

I also had this problem. It's easily solved by loging into your router and setting up the access list (under adv wireless settings on mine). You can add the device in with its specific mac address and by doing this I was instantly able to use wifi.

It's not an issue with mac address filtering. I know this issue because I have the same problem with the wifi router at the office. I can connect without any problem at home but It just won't work at the office.
DHCP server assigns an IP, but if you try to ping any IP outside LAN you'll get network unreachable.
I didn't have time to test a bit more, but I'll try to change the mac address of my wlan in order to test if the problem relies in there. The idea is to assign the same MAC Adress I have on WinMo. This will be very useful also to people with 2 HTC HD2 using the same ROM and Kernel.
BTW, I'm not using MAC Address filtering, this issue has nothing to do with it.

I have the same problem here ..
Please help me buddy!
thank you in advance

I tried this switching in and out of Airplane mode in Android with varying degrees of success. The problem itself seems intermittent for me - sometimes I get a decent amount of time with successful access and sometimes I don't. Similarly a reboot (of Android) may or may not work for me. I am using kernel version 2.6.32.15-gd09adbb gcc version 4.4.0 and is dated Thu Dec 30 19:14:35 CET 2010 for me. I notice I am more inclined to have an issue with Market even than with Firefox. Also it is more of a problem now than with a previous kernel version (but it had problems too if I recall correctly). I upgraded because I am having difficulties with getting the USB link to work under Android (but that problem is still there). It did seem to work well for the first few hours after the upgrade, but since then...
I did notice that under MS WM, the MAC address is quite different to that recorded by my DHCP server (a unix box the other side of my wireless router) for Android. The Android one looked like it was a stock standard number sequence, so fabricated. I wonder where that is set on the phone?
I also noticed that the phone does not have the usual (for Linux) resolv.conf file that often gets configured by the DHCP connection process. Further, entering a host IP in the /etc/hosts file does not necessarily mean that a command like ping will find it every time. Of recent I have not been checking that - I have been using the IP address of my unix box to do ping tests to. The network does (of course) shut down when the phone goes into sleep mode, but does wake up, even responding to a ping from the unix box. Running up Market, though, seems to kill the connection every time now (but a weather update won't).
A further observation: if I get the Wi-Fi network connection to reset itself (straight forward when the lease expires), it is hard to get it to reset itself until after the next lease expiry for some reason.

I did some further tests. I don't have a pipe (|) key on my HTC HD2 that works so the following commands are a little long winded.
localhost / # getprop > /data/tmp/props
localhost / # grep dns /data/tmp/props
[net.change]: [net.dnschange]
[dhccp.eth0.dns1]: [192.168.10.1]
[dhccp.eth0.dns2]: []
[dhccp.eth0.dns3]: []
[dhccp.eth0.dns4]: []
[net.dns1]: [192.168.10.1]
[net.dnschange]: [49]
localhost / #
Now 192.168.10.1 is my (Unix) DNS server.
When I do the following on the phone
localhost / # nslookup 192.168.10.1
(or even localhost / # nslookup cicada or even the fqdn of the server)
and I tail -f /var/tmp/named.log on the server (where I set up logging for queries and resolver categories for this test)
I see no action at all on the server and on the phone I get
localhost / # nslookup 192.168.10.1
Server: 192.168.10.1
Address 1: 192.168.10.1
Name: 192.168.10.1
Address 1: 192.168.10.1
localhost / #
localhost / # nslookup cicada
Server: 192.168.10.1
Address 1: 192.168.10.1
nslookup: can't resolve 'cicada'
localhost / #
and the same for the FQDN.
The DNS server does not even see the request for forward or reverse lookup, strangely enough. But it is seeing the requests from other machines with logs to the reverse lookup from those other machines looking like:
10-Jan-2011 22:21:57.953 queries: info: client 192.168.10.20#38971: query: 1.10.168.192.in-addr.arpa IN PTR +
So, not only does the wi-fi link drop when Market is run, the DNS is behaving strangely to terminal based testing. Further, an update of the weather does not show any traffic in the DNS server log (at least for the logging level I have set up) even though the weather does get updated. It makes me wonder what DNS it is really using.
The other avenue I want to check is DHCP time-out, which I have been keeping an eye on (it does seem to time out and not update, but there are also other issues that suggest the problem is not a time-out one). That will have to be another day at this stage, though.

what channel is the router using for wifi?

[Q] Limited connectivity wifi issue

I just bought a Rogers arc and everything is great so far, except the wifi. For whatever reason when i try to connect to my home network, although it recognizes it and connects i get a "limited connectivity" which effectively does not allow me to use wifi at all. ive tryed rebooting the phone and reseting my router (which is a D-link DI-524.) any help would be appreciated.

you could go in the router settings and register the phones mac address to a ip of your choice. it should do the trick i think...

I finally figured out what the problem was, i had to update the firmware on the router and then manually add the MAC address like dogggie said and after a reboot voila!

I don't want to make another thread since my problem is similar to this one. So in my school there is a hiden Wi-FI network and it has got a password, but we know Name and Password, so we can connect to Wi-Fi. But here is the thing: My friend who has SGS2 connect's without any problems, but everytime I try to connect to Wi-FI i get "Limited Connectivity" mesage. Is there any way to fix this? Can I somehow get Gateway and Netmask from router, so I can set static IP on my phone or sometheing like that?
Thanks for answers.

I have the same problem. Hidden Wi-Fi in school, limited connectivity. Works for some people, doesn't for most.
I have used CM7 for some time and the Wi-Fi worked with it, but I flashed the stock ROM back and now, again, it doesn't work.

Oo, another one form Slovenia Lep pozdrav. Šola je pa TŠC Kranj.
It also worked for me when I was testing Offical Beta ICS, but now I am back on stock 2.3.4 and all I can get is limited conectivity

Today it works. I have just manual set gateway, DNS servers, netmask and my own IP.

Cool. Mind sharing the values you used?

Wifi obtaining ip address....

My Wifi connected to my home router perfectly until I flashed the custom rom.
Now it wont work. the phone recognizes my network, then tries to connect but it pauses at the obtaining ip address bit and doesn't connect?
I tried to restart the router. It doesn't work.
I tried to reflash the rom or offical rom (KE7). It doesn't work.
I also tried to delete the file /data/misc/dhcp/dhcp_list, but there are no "dhcp_list" file inside 'dhcp'
Do anyone have another way to solve this problem?
Thanks

Could be a problem with the router, are other devices able to acquire IP addresses from it correctly?
Perhaps you should assign a static IP to see if that makes a difference.

I am on KE7 stock rom with root and had this problem too. It just started yesterday and got stuck at obtaining ip adress. So I switched WIFI off and flight mode on and after some seconds wifi on and flight mode off and it connected. I also noticed that now sometimes when it is in standby it disconnects from the wifi network (but wifi is still ON) and when I wake it up it connects to my network.

Me too, same problem.
If wifi is ruled on "sleep when screen turn off", it don't wake when screen turn on.
It stay on " searching for IP adress...".
For the moment, I'm forced to leave wifi on "never" and I use Juice defender for disabling wifi on screen off.
I really think it's a common pb with SGS 2. May be it will be fixed with 2.3.4.

Same problem. I 'fix' it by turning off wifi then turning it back on and it gets an IP address immediately.

same problem here with a dlink dir-615 router. from time to time the phone can't get an ip, and it only works if i reboot the router. didn't try with another router yet ( well, i connected to a few more but not frequent so i can see if there are problems), but i ordered a new one anyways since the dlink also crushes my battery too.
try posting the brand/model of the router you have problems with, maybe there's some specific ones that are troublesome.
d-link dir-615 here / ke7 stock - rooted

I also have a dlink router. But I get the same problem with a Belkin.
With my first SGS, no problem. I really think it's a specific issue on SGS2.
I'd read in some place that 2.3.4 will fix some wifi problem known for the moment on 2.3.3...
Let's see...

I'm seeing this with both my home router (Netgear WNDR3700) and my office router. Disabling & re-enabling WiFi on the SGS2 solves it -- fortunately, it's easily accessible on the notifications panel.

Same thing with Dlink dir 815.

Same thing here with Draytek 2820 router, all other devices (PC's Phones, PDA's etc) have no problem. SGS2 however needs WiFi turning off when waking from sleep to get it to obtain an IP address again. However my HD2 also running Gingerbread 2.3.3 works faultlessly.

KF2 seems, for me and some others, fix the problem...

hi
lucky me, i thought im the only 1 having problem with wifi
my problem, same as the others
the wifi try to connect (obtaining IP) and then disconnected
it will scan again, same thing will happened
try with all type of protocols, wifi b,g,n wep, wpa, no passwd
results still same
try to connect wifi at my office, results also the same
im on KF1 using dlink 615
hopefully someone can help us
tq

Just got my Galaxy S2 today. Cannot connect to wifi network on G or mixed mode, with or without security - just tries to obtain an IP address. Ridiculous.
Any help ? Quick search on Google doesn't bring up too much. There does seem to be an app called "FXR Wifi" but I don't expect to use that on a brand new phone.
Update: Upgraded my router's firmware (WRT54GS) and it works !

I have the same problem with my SGS 2. I can't connect to an AP - NETGEAR DG834G.
I found a partial solution to use my phone with my AP until I solve the problem. In the Wi-Fi settings menu enter Advanced mod and set the IP address, Gateway, Netmask, DNS1 manualy (by touching <Use static IP>). If you don't know what IPs you have to set for IP address, Gateway, etc. just connect with you laptop or desktop and use the settings from your computer. Just make sure you type a different IP address in your mobile (not the one from your computer - for example in you computer you'll find something like this: 192.168.0.3, you'll have to type in your mobile something like this: 192.168.0.10). The rest of the settings have to be identical.
Good luck!

To solve this "obtaining ip address problem". Set the following manually in the advanced configuration and save it.
1. ip address(your choice).
2. subnet mask(255.255.255.0).
3. default gateway(192.168.1.1).
4. dns servers(8.8.8.8,8.8.4.4)
Note: The above given values are the most commonly used, you change it if you want so.
After entering these values manually(and correctly), it will connect to the networ in 1 or 2 seconds.

like mine SG s2, wifi connects works perfectly at home and friends place,
but stucks at obtaining ipaddress for wifi, at the mall and college, ( where it needs first login page for authentication) ( or to agree user terms and regulation),
any idea, how to fix this issue.
Thanks

mine also does this where it doesn't get an ip. Reboot your router or just disable and re-enable the access point feature on the router and it should work without having to reboot it

Hey guys! Did you find a fix for this problem? I have the same thing happening right now. I tried at different places, home and country house with Zyxel P660HN and Cisco E4200 respectively. Stuck at obtaining IP address...

Does anyone have a proper workaround for the obtaining IP address?

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

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.

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).
