[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] Xoom WiFi inoperative

My WiFi was working fine on my Xoom, and now it gets stuck while "obtaining IP address." It says for a split second "remembered" as if it was connected and starts the ongoing circular process of "obtaining IP address" all over again. I saw that galaxy tab users had this same problem and found a resolution by connecting "static" instead of "DHCP." I didn't try that as I honestly don't know how. What I do know is that there are a few devices like my OG droid, my laptop, my mothers' laptop, my xbox 360 that are connected to the same WiFi network. This randomly happened, when I decided to disconnect from WiFi to run a speed test on 3G and I was unable to connect to WiFi ever since. I tried unplugging/plugging the routers, turning the Xoom off and on, and even went so far as to doing a factory reset on the Xoom and I still can't connect. 3G works fine, but I have a 1GB cap and I would rather only use that while I'm on the go, and obviously WiFi is definitely faster. If I can't resolve this, I still have enough time to return this thing. Call me a newb, but I need a little help!

I know you said you did a factory reset, but google stores wifi passwords in the cloud now. Try making the xoom forget the network you're trying to connect to.
My only other thought is that you need to go into your router's configuration and remove the xoom as a remembered device.

How do I get the xoom to forget the network? How do I remove the xoom as a remembered device? Sorry but I really don't know how to do that..
EDIT: I went into settings>privacy>backup and restore> and unchecked "back up application data, Wi-Fi passwords, and other settings to googles servers and was still unable to connect.

I think if you long press on the wifi network it will give you the option to forget it.
As for the router, do you remember setting it up? The settings pages where you set the wifi name and password and such.. it should have a section where it tells you which devices are connected.

I have pressed "forget network" on the xoom several times when trying to connect. As for the router, do I remember setting it up? No, as a matter of fact I didn't set it up. Could I configure this thing from my laptop?

Of course, anything that's connected to the router should let you configure it. It's too complex to explain here, but you need to enter the router through it's IP address and find the configuration.
Find the manual for the router you have and go from there.

I'll try to look into that, any idea as to wtf happened? This is beyond an inconvenience..

I'm having much the same problem. After entering the passphrase it says 'obtaining ip address from....' and thats all. It never connects??? I have tried 'forget' several times and no luck.
I have been able to connect to unsecured wifi with no problems.

Use the free app "wifi static". Config to assign you a static IP on that network only and dhcp on others. Its something within android as I have the same issue in my phone with a few networks but not most.

OK, tried it. NO GO! After entering the passphrase it STILL says 'obtaining ip address from....' I may be doing something wrong with the app since it comes with absolutely NO directions. If this is going to be an issue average folks will take it back!

Have any of you with this issue verified that the DHCP scope on the wireless network is not full or that DHCP is even allowed? The fact it works one place but not another tells me the issue may be with the network and not the device.

I also had this issue, I ended up fixing it by upgrading my router BIOS. the version that was on there was dated 2004 (yikes), and though the most current update was only 2006, it seems to have fixed the problem.
That or the reboot after the update as previous poster said and the update didn't really have anything to do with it, but either way it got fixed.

[Q] Problems connecting to wifi network: looping "obtaining IP address"

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

Can't connect to wifi - "avoided poor internet connection"

I've been having problems trying to connect my friend's Nexus 7 (32Gb) to my home wifi. I tried 4 (yes 4) wireless routers, and it refused to connect to any of them. It would prompt for my (WPA2) login credentials, then spend a few minutes trying to connect, then give up and try another access point. It would mark the AP just tried as "avoided poor internet connection".
The routers I tried were:
- Belkin Play Max N600 HD
- Buffalo WHR-G54S
- Draytek Vigor 2920n
- O2 Broadband wireless box 5
The signal strength from all of them was shown as excellent. I tried the O2 wireless box with WEP encryption instead of WPA2 and that didn't help.
I was able to connect both a Samsung Q330 laptop and a Galaxy S3 to all of these routers, so they all appear to be working fine.
As I'm shortly planning to buy a Nexus 7 I'm keen to understand what sort of problem might stop it connecting to my routers!
Any ideas?

Hi,
I have the same issue and i foud that it is due to the inferior frequency of my router wich is 2.4ghz.
so i you did found a solution please share it,thanks in advance.

All routers use 2.4 GHz unless they are branded/advertised as being 5 GHz. The Nexus doesn't even support 5 GHz. The warning is more about the actual internet connection anyway. As for removing this warning, you can easily disable it under advanced WiFi settings.

I subsequently acquired my own Nexus 7 and had no problem connecting it all of the routers that my friend's Nexus 7 wouldn't connect to. I'm guessing that I was running a newer ROM. I still have no idea why my friend's unit wouldn't connect

Your friend should return his faulty N7 for a replacement.

If you can access the router, do a reset or reboot, sometimes a refresh would get the "hand shaking" working again, switch to an alternate wireless channel as it could be interference from other nearby routers.

after some research i found this .
and for the "avoid poor internet connection" in the advanced menu ,in 4.1.1 the is no such option in the menu .

Your custom rom is not the same as the OP. There is no option you suggest on a stock rom.

I had the same problem with my PC...
usually the problem is with the router, restart the router,

SOLUTION
Figured it out...go to the WiFi settings, hit the menu key and choose "Advanced", and uncheck "Avoid poor connections".
There are lots of android phones without the above mentioned option(The place where you can uncheck your "Avoid poor connections" )
If you're in that case I've got an alternate for you
1. run command prompt and type ipconfig
2. note down your ip address
3. now what you do is change the last digits after the last point and give the command
ping 192.168.1.xx(changing the last digit or last two digits)
it'll say pinging and BLAH BLAH BLAH
It'll give details about the sent and received packets of data
And also LOST packets
NOTE: If the lost =0( 0 % lost)
4. Then note down the ip address which you've given after the command ping **192.168.1.xx**
if the lost= (100 % lost) or may be some other percentage of lost... it means there is some loss of data packets
so never note down that..... repeat the process 3. changing the last digits of your ip address
5. Now once the lost percentage is 0 %
6. go to settings->Wi-Fi-> And long press the network to which you wanna connect your device
7. Choose modify network
8. Enter the password(If there is any and do not press save)
9. Enable show Advanced options
10. Change the ip settings to static
11. Enter the ip address which you've noted down in steps 3 & 4
12. Enter the noted ip address in the ip address
13. Also Enter the gateway address in the column below which you find from your cmd prompt giving the command ipconfig
14. The network prefix length ,DNS 1 And DNS 2 Will be automatically assigned
15. Now click Save
Thats it .......You're Done
incase if the Avoided poor connection occurs again repeat the steps from 6 till the end giving the same ip address which you've noted down
ENJOY ! ! ! ! !

I've fixed it
Hello.
I fixed this bug, it isn't poor conection... it is an error about dhcp server in the android 4.x
First you need to download and install ipconfig app from aptoide
So you need to try to conect to your network, while it is showing obtaining ip adress, you should go to ipconfig app (be as fast as posssible)
Finally you should find your ip number and your gateway, if you don't, click in refresh.
Now go to settings and long click into your network, so click in advenced settings and change dhcp to static IP, here are the recommended settings:
IP- get in ipconfig
Gateway- it will automatically set, the most used is 192.168.1.1
Prefix- 22 or 24
Subnet mask- 255.255.255.0
Dns1- 8.8.4.4
Dns2- 4.4.4.4 (no need to set)
I wanna develop an app to do it automacally, but I need help... I'm pretty noob, I've got only 14 years old
Edited: Oops, I didn't saw your solution, anyway it doesn't work on all routers cause some routers are set to another ip
I'm glad to help you

Wi-Fi connection intermittent failure - requires router reboot!

I've been having this issue with both my Nexus' - my 10 and my 7.
I'll look up and find my connection bars greyed out or none showing and my connection dead. All the other devices on the network will be functioning just fine, just the Nexus will have no connection (I have two laptops - one Mac one PC - several cell phones and sometimes a printer)
Looking at the settings the network will show that it's either trying to connect over and over or just "saved".
Attempts to log back in will be unsuccessful with the device seeming like it's failing to get an IP address our something.
The ONLY way I can get reconnected is to reboot the router itself. Quite a drag...
Google doesn't seem to turn up anything, and forum searches likewise have not been successful
(One problem is there's a lot of 'noise' in results from searching trends like "Wi-Fi", "connection", etc).
Anyone have a clue? It's annoying, especially when it happens somewhere I don't have access to the router (coffee shop etc).
Mostly tho, it seems to happen at home.
I'm running a Belkin N150 router with out-of-the-box settings.
Any help would be greatly appreciated!
Note: the problems don't always show up on both Nexus' simultaneously. Sometimes one will have a connection while the other does not, and sometimes they'll both be disconnected.
Every other device's connection will be fine tho.

i think ur facing ip conflict, new routers should not have such issue but ur nexus devices seams to have such issue.
try this, manually setup ips in ur nexus device (give ips as far from ur normal ips e.g nomal ip 192.168.1.5-6-7 u try 50-51-52
and also give google dns in ur manual settings
8.8.8.8
8.8.4.4
grayed out signals means ur device cant resolve dns (usually cant connect to google)
replay with updates.
P.S: if you have connected to ur router via push button process then also try connecting to it via entering wifi password key.

Download free App from Store - "Wifi Analyzer" to scan your 2.4 Ghz band to see if interference from other nearby routers on the same channel might be causing interference. Switch to a less congested channel might solve the problem, Fios routers tend to default to Auto, usually on 1, 6 or 11 - your signals might be "fighting" with several others routers trying to "hand-shake" between the devices - do it while rebooting the router.
Take a look under Settings - Wi-Fi and then "Advanced" to see what is your N7's setting on "Keep Wi-Fi on during sleep" - if it switched into energy mode/sleep, it might stay there & wake up to resume. This is known to happen to Android devices but iOS ones too.

https://code.google.com/p/android/issues/detail?id=40065
This is a known problem. Read the above for more information.
My solution https://code.google.com/p/android/issues/detail?id=40065#c737
I have a N7 32G and an ASUS RT-N66U and had been having disconnection of my Wifi during use. Sometimes, turning on and off Wifi works but at spots in my house that's a bit further from the router, it will not connect. A few weeks back, rebooting my router helped for a few days and same problem occurred again. Then I tried static IP, and that helped for a few days. The latest test I did was to increase the "Network Key Rotation Interval" on the N66U from the default of 3600 to 7200. Crossing my fingers and hoping that this will finally solve my disconnection problem. My Wifi is set to 2.4GHz band, Wpa2-personal AES.
My firmware https://code.google.com/p/android/issues/detail?id=40065#c743
is firmware is 3.0.0.4.260 which is the latest.
Hope this will be useful for you. :thumbup:
