[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.

[TIP] Wifi connected but no internet connection!

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?

Turn off wifi optimization on some android phones help.

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?

[Q] WiFi problems...

Anyone having trouble with WiFi? With my home router it just keeps cycling between "Authenticating" and "Obtaining IP Address". It will connect with my Nexus 4 if I use my N4 to create a WiFi hotspot. My old N7 connects to this router just fine. It has full bars and is using WPA/WPA2 PSK security. I tried WPS and it didn't work either. Anyone else having issues or have any ideas? I want to root this, but I need to make sure the wireless is working correctly first.
Edit: It appears to work correctly if I switch to 2.4 GHZ mode, but will not connect correctly under Auto or 5GHZ mode. Curious if anyone else is having this problem.

[Q] Wi Fi Connectivity

Hi all,
Lost info for my original account, so I made a new one.
Straight out of the box my HTC One has not been able to connect to my router. It gives me the message that it's avoiding a poor internet connection although under the connections it says the signal strength is excellent. My laptop connects just fine. My Razr HD connects just fine, but interestingly my wife's galaxy S3 will not connect either. It gives her the same message.
I've tried changing the bandwidth from auto to 2.4 to 5. I've tried forgetting the network. I've tried static internet connection with IP address 192.168.0.15 and also 10.0.0.11 I enabled the DLNA, there is no useable option to clear cache or clear data and last of all I did a factory reset.
None of these worked. DLNA and the static internet connection have allowed me to connect, but it's not really connected. I'm not sure what's happening. It says connected with excellent signal strength, but nothing connects. No internet, no netflix, no nothing.
I think it might be something to do with the router itself, but I don't think I'll be able to get any information from netgear's people. It's not broken (other devices connect just fine) but these newer smartphones seem to have a problem with it.
Neatgear N300. Also, I tried WPS connection as well. No Dice.
Thanks
Update-I've found a -similar- issue in this forum regarding specific bandwidth connectivity issues for dual band routers. One of the suggestions was to update the firmware. I haven't been able to do this successfully. Still trying.
Update 2-Tried to connect to Safeway WiFi today. No luck. It goes to the sign in page and it's just blank. At home it says the page is unavailable. At safeway it's just blank...
*bump* No help at all?

[Q] FireTV XBMC Error 2: Share Not Available (Only when on wireless,not Cat5)

I was wondering if someone out there could possibly help me out. I rooted my FireTV and loaded XBMC on it, has been working flawlessly. It had been connected via ethernet cable to my network, and I have been able to play everything on my server without issues. I decided I wanted to move this FireTV to the bedroom TV, and had to switch to wireless since I don't have an ethernet jack in that room. I connected to Wifi without a problem, and am able to stream off XBMC plugins without any issues.
For some reason, as soon as I switch to using wireless, I am unable to connect to my network share off my PC in the basement. Everytime I try to browse to the SMB share to connect I get an 'Error 2 Share Not Available' and 'Could not connect to Network Share' error. I am able to ping the ATV when on wireless from my laptop without any issues, and as soon as I plug an ethernet cable back in, it works flawlessly.
I apologize if I'm not posting this on the right forum, but does anyone have any thoughts on something else I could try to get it to work? Any help would be greatly appreciated!
Thanks,
-J

Most likely you are connecting to the guest network on your wireless !!! .
some routers allow you to create 2 wireless sids one to access all resources local and remote and a secondary guest sid that allows access to the internet but not to your local resources.

Try using the IP address to the server. Possible the local DNS server isn't catching up with the wifi

Thanks for the help! After it didn't work for multiple days, I happened to try it yesterday, and it just randomly started working. Not sure what happened, even the ip address wasn't working before.

I used to have issues with shares, especially SAMBA. I began adding shares manually like in this video and it fixed my issues http://www.youtube.com/watch?v=dTBspxh7CgI

error 2
​if you are receiving this error its because of your router either its bridged enable or you have to routers connected such as a moden with built in wifi from say comcast an your personal router-J[/QUOTE]​
