[TIP] Wifi connected but no internet connection! - Samsung Galaxy Nexus

At some points in your life, one of your Android devices connect to a wifi router, but can't connect to the internet. However, your computer, laptop or iPad will connect to that same wifi and use the internet just fine. I've looked everywhere on the internet for solutions, some of them are:
+ Turn off and on both modem and wifi router
+ Factory reset wifi router
+ Battery pull your phone, wait 30s and put it back
+ Reflash stock or custom ROM
+ Change DHCP IP setting to Static
+ Disable security (WEP, WPA) on wifi router
+ Check DNS server, gateway IP address for correctness
Fortunately, I stumbled upon this old thread last night -> http://forum.xda-developers.com/showthread.php?t=1371794
It helped fix the internet connection temporarily, turning off and on wifi on phone caused the issue to repeat.
In summary, he found out the correct MAC address for gateway was mismatched with the one on his phone. Even though the gateway IP address is correct (example: default gateway IP 192.168.1.1)
Upon further investigations, I found out my Wifi ROUTER has the same IP address with my MODEM (192.168.1.1) This IP conflict causes the phone to recognized the WIFI ROUTER's MAC address as the gateway's MAC address. This problem mostly occurs on Android phone, not computer (I'm no tech savvy so I have no idea why)
Simple fix: Go to wifi router setting page, change the IP address on wifi router to different number (other than default 192.168.1.1), and the problem should be fixed.
Please help spread the words to fellow Android lovers, I'm sure a lot of us have struggled with this problem :laugh:

I'm one guy who is desperately looking for a solution to this.
Unfortunately the solution you gave didn't work.

Hi
i have a problem with wifi. it remains connected but loses internet access randomly. i found this solution:
"In the wifi networks, select the network you want and select ‘Forget network’
Turn off the wifi
kill all the apps with your task manager
Turn on the wifi again
Connect to the network
Check the internet connectivity
If still the problem exist, switch off the phone and redo the above steps"
it solves the problem, but it happens again after some minutes. actually, i also installed an app named "wifi fixer" which does the above process automatically. when the program is active, it turns the wifi off and on every 2-3 minutes. and the phone has internet access when the program tuns the wifi on.
any idea?

2 years after the last reply I am having the same problem. My wife and kids all have internet access on their phones, tablets, desktop and laptops all from the same modem router yet I am unable to use the internet on my Galaxy S2 mobile phone even though my phone says connected to Wi-Fi Network Netgear 06.
The Mac address solution provided isn't applicable to my situation as my Mac address on my mobile is different to my modem router Mac address.
Any other solution?

WiFi Problems With 2 Networks

Hi
I have a wifi AP at home, and one at work, Both use WPA-PSK with mac addy auth. SSID Visible cause sh1te WM2003SE OS cant cope with hidden SSID.
Get a whole load of oddities from the XDA IIs. Both SSID's and keys are listed in the wifi setup on the device. What I would expect is that if I switch the device on when I am within range of the AP @ work, it connects to it no fuss, likewise, when I drive home, switch XDA on it connects, no fuss, unfortunately this is not usually the case. The following are in order of likelyness to occur!
Problem 1
Sometimes I switch it on, and it sits there searching for eons, never finds AP. If I disable and then re-enable wifi on the XDA then it connects.
Problem 2
Sometimes, the XDA will tell me that its connected to my home network when I am at work - it isn't!
Problem 3
Sometimes I switch it on, it connects to the AP, but no net connectivity - looking. Using PPC Ipconfig, I see that device never managed to get an IP addy. Stop, start wifi problem resolves
Problem 3
Occasionally, the PPC forgets the shared secret, and I have to re-input it, start/stop wifi before it will connect to the AP
Problem 4
Sometimes, it just BLUNTLY REFUSES to connect to the AP if I do the above. In this case I try all the above with a soft reset as well. If that fails then I need remove all the wifi AP's, soft reset, wait (ages) for it to see a new AP, enter the PSK then it will connect.
It also struggles to connect to other APs (wifi hotspots). Things work a whole lot better when there is just one AP involved (i,e not work and home).
Prob 4 occurs once/week, prob 1 occurs every day, others somewhere between. All problems are of course COMPLETELY UNACCEPTABLE for a product that has been released to the consumer.

Hello Veledron,
I've a similar problem: at our company WLAN is set up to reqire WPA and authentication with user certificates. Since it is not possible to import user certificates in Windows Mobile 2003 SE "out of the box" I found out how to do that - it is described here
http://www.jacco2.dds.nl/networking/crtimprt.html
a little bit difficould procedure, but it worked - I can see my personal company certificate in the private-certificate store of my MDAIII.
The problem is, that I can't get a connection. WLAN-Manager says "connected", but I can't receive an IP-address - and in the logs of our Cisco-APs I can't see anything from my PDA. What also is a little bit strange for me: the MDAIII does not remember the setting "authentication with certificates", it always switches to "authentication using PEAP"...
any idea?
thanks
Gerald
Hi Veledron & gekap
I too have similiar problem with my netgear router at home. It seems that everytime it connect to the network it will just keep scanning eventhough it prompt that it already connected. It been 2 days and still i cannot manage to connect
Hopefully there is a solution to this problem.

There is.... Turn off AP, or move device to location where it is out of range, remove all WiFi profiles from device, hard reset, turn on router. wait (ages) for device to realize that there is a wifi ap nearby, enter PSK, all is well.
There seems to be no pattern to the WiFi failures, I have to do the above maybe twice a week to get it to connect. When the device gets itsself into a poor state this is the only way.
You cant delete an active profile, and the profile list only appears when wifi is turned on (stupid!) hence the need to turn off the AP.
Nigel
Hi Guys,
I manage to solve my wifi problem,
i just add the XDA IIs mac address to my netgear router plus assigned a reserve ip address based on it mac address and was able to connect successfully with no problem. Hope this solution helps.

Hi,
thanks for the tips, but all of them are not a solution for me. I do not have any problems connecting to WLANs using WEP or to unencrypted WLANs, but i guess that there are problems with WPA in the PDA2K. I think the guys of you who have succussful connected to a WLAN using WPA have done that using WPA-PSK, not WPA with TKIP as encryption-method and PEAP or certificates as authentication method over 802.1x.
In our company TKIP is mandatory, and it is necessary to use certificates for authentication - this can be done with either EAP-TLS (so called "smartcard or certificate" in the setup-menu of the PDA-2k) or using PEAP. I've troubleshooted this a lot, and I can't see any authentication packet coming to our Cisco-APs from the PDA2K using this methods (I've turned on advanced logging on the APs to see any little bit...).
I fear the worst, that the WLAN-driver of the PDA2K does not support TKIP! Of course WPA is supportet from Windows 2003 Mobile SE, but in my opinion that is not enough - the card driver down the OS must also support the whole WPA-Standard, and it seems to me that the PDA2K driver does only support WPA-PSK. I found an article which can be an explanation of the problem:
http://www.socketforum.com/topic.asp?TOPIC_ID=2924
So I've 2 questions to you:
.) which driver version is installed on your PDA2Ks? (you can find that in the registry under HKLM\SOFTWARE\Drivers\Wavedev - I've: Common: 0.04.01, Device: 1.06.01 GER, DriverVersion: 0.08.00, Patch: 1.00)
.) has anyone of you ever connected to a WLAN using WPA (not WPA-PSK!)?
thanks
Gerald

XDA IIs Wifi and lockups

Does anyone have a problem with their wifi locking up their xda iis? I have bought a linksys router and am getting frequent lockups when using wifi. I am using the shipped O2 rom, thanks
I have no problem at all with Netgear router. Try changing the connection speed setting in the router to the "b" mode only. Hopefully this can solve your problem.
No problems here either I'm afraid. I'm using a Draytek Vigor 2600VG at home and at work there are two of us with XDA IIs using a Linksys BEFDSR41W wireless router and no problems there either.
Sorry! :-(
Try a hard reset (gulp!) and see if you still have problems (Without anything else installed that might be inteferring) otherwise might be a faulty unit perhaps.
--Neil
I second what xanth said, I had the problem where wifi would not turn on, so I hard reset and installed each software back individually the problem was Calligrapher 7.3 did not like being in Storage or Storage Card only in Main memory (go figure)

I use the XDA IIs on a variety of wireless networks and experience problems with an alarming regularity. The most annoying is the fact that the top bar seems to loose functionality, when using wireless!!
I will actually add that I do seem to have problem with the "range" of WiFi.
I need to do more testing, but it doesn't seem to be more than 20m or so before have communication issues/timing out :-( Will have to find out what our walls are made of!!!
I have problems connecting sometimes. I regularly use three routers, Draytek, Buffalo and Belkin. The only time that it locks up is when using skype. The skype problem is a known issue with no cure.

I am having a problem where my Siemens SX66 will loose connection to my Microsoft MN700 wireless AP on occasion. -It simply appears as if the Wifi radio shuts itself off.
Weird.....
Wifi has never worked for me. It simply doesn't work in the way nature intended.
The main problem (as far as I can tell) seems to be that it cannot get DNS or IP configuration settings from my router (Belkin 7630) automatically.
It can connect to my wireless network without any hassle, but that's about it. If I enter DNS and IP settings manually it works fine. But this is unworkable if you want to connect to another wireless network.
If I can't sort this out by next week I'm going to sell the unit on eBay. It's been nothing but a pain since I mistakenly bought it in December.
Wifi is a nightmare on this device! I'm going back to Nokia.
I am going to do a hard reset and test to see if i still get any freezes. Anyone know of any software i can use to backup my text messages?

Hi guys,
Haven't had too many issues with WiFi over here - standard O2 Asia ROM (with the BT 3500 update).
I'm running a Netgear WG602 @ home with 64bit WEP and a Dlink AP2100 @ work with WPA-PSK. No connectivity problems at either location, both DHCP. It does however take a few minutes to connect, but this is on the odd occasion.
The only frustrating thing with the WiFi is that I have to soft-reset often to turn Wi-Fi on - any ideas? Hopefully O2 will fix this in the next ROM. Other than that, I've had the Nokia 9500, P900/800 and this is by far the best device for the power user.
Just me 2c!
Cheers

Wifi is on all the time on my device, sometimes when I switch the device on while within range of an AP it does not connect. Often switching wifi off and then onn again causes it to connect. If this does not work then I can often go into the network dialogue section, and see the network marked as 'availble' but not connected (why it sometimes does not auto connect I dont know). Tapping connect usually cures. If that does not work then I too need to soft reset.
I hope like you that they fix this cause its damned anoying. I will be interested to see what the Benq P50 is like when its released. I shall get one from expansys to test and ship it back within the 7 days.
Nigel
As for those having problems with specific access points. It is not nessesarily the fault of the blue angel. It seems to me that none of the manufacturers of wireless kit understand the term 'standard' they all seem to have their own take on it, which is why kit from different manufacturers refuses to talk to each other. I am of the opinion that they do it in purpose to lock you into using their client cards with their AP's !!
Try it with some non Belkin kit and see what happens.
Nigel
Well i tried a hard reset and didnt install any apps and tried connecting to wifi again and still got a lockup and loss of connectivity. Im going to swap the router for another make and see what happens
Swapped my linksys router for a D-Link and so far no problems after 2 days. so looks like my problem was my router.

XDA IIi and wifi
I just bought one of these and can't get it connected. I have a netgear wg602 access point. When I finally figured out how to set the IP manually (the 02 xda tech support said it can't be done - maybe they're right ;-)
I now have it saying it's connected, with right IP address. My DNS and gateway are set up for the wireless adapter in network adapters. The signal is average. The XDA says wifi is connected. The access point even says it's authenticated and associated - same as my other stations.
Only problem is, internet explorer doesn't find any web pages - says "The page you are looking for cannot be found" (works fine through GPRS)
Also, terminal services times out trying to connect to an internal IP address (to eliminate DNS as a problem)
So, anyone know how I troubleshoot network problems - it looks like a TCP/IP issue? Can't find ping or arp etc. I've also tried an IP address that I know works on the network.
thanks for any help

Hi
For ping, ipconfig and stuff, head to http://www.cam.com/windowsce.html
I have had multiple issues trying to get wifi working reliably. It still fails now, but there are a few tricks to get it working again. Most of my wifi issues have been due to regular use of three AP's [email protected] and [email protected] along with GPRS and VPN.
To start with I suggest setting all the ****e in connections (internet and home network to 'My ISP' then goto your wifi setup, network adapters, and tell it that the wireless card connects to the internet. Now, tap ok, and goto tools, network cards, tap the active connection (it must already be connected) and ensure that its set to internet.
Next soft reset the thing, and wait for it to connect to yr wifi. Now, use the ipconfig tool and ping tool from the above site to check that all is OK. Check that its got the default gateway right and a sensible LAN IP.
I have found on occasion that I can be connected via wifi, but that the device is still trying to talk using an old IP allocated by gprs which means nothing to my lan! IPconfig will show if all is OK.
Whoever wrote the whole of the networking system (and its terrible gui's) on windows mobile wants shooting. I usually have 2 VPN profiles setup under my work network. If I leave it set to that, and use wifi from my lan to connect to the internet all is fine. However if I try and access a local server, the damned thing starts trying to connect a vpn (it aint inteligent enough to work out that the IP I asked it to connect to is local).
I have been trying to find a setting for all this networking rubbish that allows me to do *everything* without reconfiguring each time - to no avail.
Another thing to note is that you cant send/receive MMS messages while wifi is connected (more stupidity), it tries to connect to the MMS server using the wifi connection, and the telco blocks it cause it wants to charge you for sending MMS over GPRS. Only solution is to disconnect wifi, send MMS then reconnect wifi!!!

No problems with WiFi for me
Hmm I'm using an O2 Asia Rom as well.. and my wifi manager seems to automatically create "settings" for each AP it detects and I seem to have no problems connecting at all... been using WiFi around my house since the first day i got it..
i am using a Linksys Wireless 802.11b router..
btw I am new here.. finally able to register!
How's everybody doing?
Cannot turn off IEEE 802.1x
Has anyone had problems unchecking the 'IEEE 802.1x netwrok access control' checkbox???
I uncheck it, but then when I go back to the screen (click on the connection | then select 802.1x tab at the bottom) it has checked itself again!
The XDA IIs does not save the setting - it just keeps re checking itself 02 help have been no use - they sent me an instruction manual and it even says in one of the step 'uncheck IEEE check box'
Im am using a netgear wirelesss router and have also tried on a d-link
Sugestions - is anyone else having this problem??

[NEO] Strange wifi problem. Connects but no internet.

Hello. I have xperia neo for 1 week. It is great phone and great upgrade from my X8 but i see a strange wifi problem. My firmware is latest version - 4.0.A.2.368.
At my home phone connects fine to my wireless network and everything is stable. I do not see any disconnects, reboots or other problems. My router is linksys wrt320N and i connect at wireless N speed - 72Mbps.
When i try to connect to the wireless N network at my office the phone connects fine but i do not have internet access. I have IP assigned by the router, network is shown as connected but i do not have connectivity. I tried with 3 different browsers and with the market and nothing connects. At the same time i can connect with my laptop to the same network and i have internet. My colleagues with other phones also connect and have internet.
I tried setting static IP address on the phone but this did not help. I read that if i set static IP in router's settings assigned to the mac address of the phone this will help. Unfortunately i can not test this because i do not have access to router's settings. Also at my home i did not make such settings and everything is working fine.
Previously i have seen this problem with my X8 and the same work wifi network but it was not always present. It was present with some custom firmwares and not with others.
If you have any ideas or have seen this problem please help.
Having the same device from Globul I never had such problems for the 2 weeks I'm using it. I had some disconnects but i put the blame on my router.
if you can try changing the wifi channels
I think I've found the issue (by facing by myself)
The version neo is shippe (2.3.2) has a serious bug on AES encription.
Actually only the upgrade to 2.3.3 (no clue about upcoming 2.3.4) can fix the WPA/AES issue.
So the actual solutions are:
or change your wifi securty to WEP, updathe the phone via OTA
or use the Windows Software and update to 2.3.3.
Please note that if you use the Control Power widget it has been removed in 2.3.3
This was my problem when I had just bought my Arc.My phone couldn't surf the internet with my personal wifi network although I tried to use many browsers and also Android market. Then I reset and reinstalled my router, everything works well ^^
Ask your office IT staff to do a simple power cycle on the router and try connecting again. That may solve the problem.

WiFi stuck on Obtaining IP/Avoided Poor Connection

For some reason, my Wifi connectivity on my GNexus has gotten really bad lately. I'm trying to connect to my home router (Netgear WNDR3400), and it gets stuck on a loop at obtaining IP address then avoided poor connection and it keeps reseting back and forth. It only manages to connect maybe 20 mins in the day and it looses the connection again.
Reseting the router only fixes the problem momentarily then the next day it can't connect again. The router is working perfectly fine in my house w/ the computer and laptops. iPhone and HTC Thunderbolt are also perfectly fine.
What can I do to fix this?

Have you tried assigning a static ip address to the phone?
Also what type of network? My phone does it on a 802.1 wireless b network with identity security (individual uname and password to connect) Which is what my university uses... annoying it was, but i found out that foxfi was causeing the issue. But im assuming your home network isnt like that.
How do I assign a static IP to the phone?
My router is 802.11n. And it has network security, secured by WPA/WPA2 to be exact.
App called WiFi static will let you set a static IP within a dhcp network. You probably can do it through your router as well. I would read up on static vs dhcp if you have never set up a static IP before. Also you'll want to see what all of the clients ips are so you don't create a duplicate.

Anyone having this issue on the Verizon stock ROM 4.2.2? I cannot connect to any wifi with DHCP. The only way I can connect is if I enter at static IP. I have tried about a half dozen access points with no luck. I have even done a complete phone wipe of data and tried reconnecting without logging into my google account to sync down my wifi settings. This pretty much prevents me from connecting to any public wifi hotspots unless I can guess their IP range. I have never had anything other than the stock ROM and OTA updates. Is there something somewhere I can clear or reset to fix this? It worked at one time long ago prior to jellybean I think.

galaxy tab 3 7.0 wifi issues.

I was having some issues connecting to mobile hotspot with galaxy tab 3 7.0 wifi. It would connect just fine to my home internet. And although it would show a strong signal connection to the hotspot running off my phone it would not connect to the internet.
I found this post online and I just thought I would share here with the community in case anyone else is having issues. This worked for me.
I take no credit for this, just wanted to share it.
***************************************************************************************************************************************************************
I ve spent nearly 3 hours today and 4 hours last week trying to resolve this on my new S3. I was pretty flummoxed when the wifi signal seemed to drop off without any reason.
After much hunting, my initial hunch seems to be correct
a) Interference from other devices
b) Unable to get an IP address
c) I am just a layman when it comes to networking, but since all of my other devices at home the iPad, iPhone and my laptop seem to have no issues (my laptop occassionally has the same drop-off problem), I thought it's likely to be a phone issue rather than a router issue.
To resolve this I found another thread on the forum and I tried this, and Bingo! it worked.
Press these menu options on your phone: Settings > Wi-fi> (Choose your network by tapping on it for a few seconds) > Modify network config
Check "Show advanced options"
Choose IP Settings: "Static"
Enter these details
IP - 192.168.1.253 or 195.168.1.253
Gateway - 195.168.1.1 (I chose 192.168.1.1 since that's my router address)
NPL - 24
Netmask - 255.255.255.0 (I could not find this option)
DNS 1 - 8.8.4.4 or 8.8.8.8 (I had the latter by default and let it stay)
DNS 2 - 4.4.4.4
And save.
Presto! It just connected in a few milliseconds.
It may not be so simple for each phone, but it's certainly worthwhile to try.
Here is the link the forum thread, where I resolved it:
Good luck

I've some problem with wifi on galaxy tab 3 7.0 SM-T211 (JB 4.1.2)
When connect using hotspot laptop or tethering via other device, my wifi always scanning every 7s. make my battery run out.
I was trying use advance setting (static IP) but still same.
How to solved this problem?
instable wifi
Somehow the solution with a static ip works perfectly
I also assigned this ip in the router to the mac adress of the phone
Thanks raptorseye
