[Q] Wifi problem

i'm having trouble connecting my dhd to wifi. it can connect but i cant surf to any pages?
can someone help me?

any error message available?
have you tried restarting the router and then try again?
if fails, could you use an terminal emulator to type in ifconfig and check the IP address assigned?
wich encryption are you using to secure the connection?

no the only message i get is when i open a page it says it cannot load it

i tried restarting the router but nothing helps

lets start at the basics and work our way up,
go to settings, wireless en network, and wi-fi settings.
check if Wi-Fi is turned on. if so, look a little bit below this in the wi-fi networks section, does your network SSID show up? any info listed if you check that?
if nothing show's up, try add Wi-FI network.
if all this is working properly. and you still can't go on the internet, we'll move on.

Is this the first time you have used your router?
Try with the security off if that works turn it back on and try again had to do this a few times with some of my old routers.

i'm not totally a noob
i activated wifi and saw my ssid, i entered my wep-key and tried to connect. it receives my ipadress (it says it) and then says its connected...

i use this router more then a year and with other phones it was never a problem.
only with this phone.
last phones were SGS and dell streak now this one and problem.
tried to change channels of my router but standard its channel 6 and change or no change always problems

Have you tried turning off security?
Sent from my Desire HD using XDA App

yes i tried it without security but still nothing

do you use DHCP? if so, a change in lease time doesn't help? if not, enable DHCP
what about other networks? do they work?
(switch bands to another supported wifi band, if you use N, try G???)

a friend said that dhcp should be disabled?

It gives out the up address to all your equipment and should be on

Does your router filter out unrecognised MAC addresses. I set my router to allow access to only recognised MAC's. Try looking for a MAC Address Filter on your router.

no mac filtering is turned off

Have you assigned manual IP's?

no manualy ip

Check what ip address your phone has should be the same as your router except the last bit eg.
Router 192.168.1.1
Phone 192.168.1.3
If not they can't talk as on different domains.
If they are ok try pinging your phone from your router (if you can) or use your computer

[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

Same school.

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...

[Q] My WiFi wont work, (2.3.7 Gingerbread)HTC HD2

I Installed gingerbread 2.3.7, I flashed the radio, the clockwork, and the magldr. I did everything in the steps. The Internet works with the sim and everything. But My wifi on the phone wont. It would say "Obtaining IP Address" Then is would say "Disabled, secured with WPA/WPA2 PSK" I don't know why. Is it my wifi setting on my router. Or do I need to install something else to get the wireless to work?
Please help. I need wifi to work on this phone.

What ROM? Have you tried other ROMs?

Hey, i was facing the same issue and managed to fix it after running a check on my wireless router.
the areas you can check are:
Mac Address control- needs to stay disabled
Mac Address filter- needs to stay disabled- This was enabled on my router so i disabled it.
>>reboot the router<<
if this doesn't help, try adding your phone's mac address to the approved list. Sometimes that fixes the issue too.

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.

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).
