I am on a business and have been staying at various hotels. The hotel I am currently at I have stayed at several times but this is the first time I am having issues connecting to the internet. I have talked with their IT department and what we can not figure out is when my phone connects to their wifi it is assigned XXX.XXX.XXX.XX IP address but the phone says it is using 172.17.3.3. It was stuck at 172.17.3.3 last week and still will assign that address this week. Because of this the browser is unable to redirect me to the hotel wifi login screen. Yesterday the same issue has started on my Kindle Fire 172.17.3.104.
I am running anybones 5.10.605.9 and i guess my question is is there any way to force the phone to change or forget an ip address 172.17.3.3? They can see my phone on the network it is just that that IP address 172.17.3.3 is not the address that the network is assigning.

Hello
Is there anyone out there that know why my I phone can connect to my 2wire
2701HG-B and it gets an ip address but it will not connect to any web pages. I can see all my computers on my local network but that's it.
Thanks
Mark
Well found the problem. Just give it a static ip address..
WiFi works at home but when I go outside on a few wifi spots, My brother's desire s connects easily while my Xperia PLAY displays Limited connectivity problem. Any solution? The problem started since the 2.3.4 update.
My XPlay is rooted, if that would help.
Check what IP address the phone gets from the router. The IP should be an internal one like 192.168.x.x. My theory is that you get an external IP which can't access the web.
If you get a external IP you will have to check the DHCP settings in the router.
I was running totally stock on my Nexus until a few days ago. Decided to go back to CM again now that 10.1 stable is out. No problem at first but since yesterday my IP address is getting STUCK. At home i have the usual 192.168.1.xxx subnet address, but at work I have a 192.168.0.xxx range. All of sudden my phone is now stuck on my home IP address and it is not releasing properly and getting assigned it's proper address at work. The usual DHCP in both places. When I get to to my work network I see the usual messages, authenticating, obtaining IP address shows, then it says CONNECTED just like usual. Except it still has my home IP and thus, no network access when I'm at work. I had no issue prior to installing CM 10.1
Anything I should try? (beyond multiple reboots, and turning wifi on and off, which I've done of course). Any caches I should try clearing?
Update. Even though rebooting and turning wifi on/off didn't fix it, I connected to a different nearby network, then tried reconnecting to my work network. It then DID clear and update the IP to a proper one handed out by DHCP. It's strange. Perhaps it's a DHCP issue. Another guy on my network had the same thing happen with his phone. Anyway...I will keep poking around.
Have a Wifi issue to: can't connect to my Network(s)
To install le CM10.1 Stable, I do a complete factory reset, delete all Datas, ....etc. Installed 10.1 stable with gapps the latest.
Wifi worked fine until i do a reboot from Phone (I do this Reboot to do a backup)
Since this reboot, the wifi don't see anymore the neighbor network. I have 2 SSID: one in 2.4ghz and one in the 5ghz. Both with diferent SSID Names... I didn't touch anythings in my Wifi router settings!!
In 5ghz i see the network, but the connection is flapping between Authentication, retrieve IP, Authentication.....etc .
In 2.4ghz, network is out of range...
No problem with my Crespo, same CM10.1 Stable
Have anybody other the same issue ??
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.

(bump) By any chance, are you all using Aztech's router? I have the same problem with my Aztech router.
solution?

Had the same problem for several months. Changed my router and everything became prefect.

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?
So, weird thing started to happen last night. Both my Samsung devices ( my 2014 10.1 and my S4) started failing to get an IP from my wifi network. It would see the wifi network and report a strong signal, but would fail at the obtaining IP address. The IP assignment is handled by a Windows DHCP service running on a domain controller. I work in IT so I have a fairly extensive lab at home with routers, switches, servers, domain controllers, etc. The wireless access point in my home is a WNDR3700 with no WAN port config as my firewall/routing is done by a Cisco ASA 5505. All the 3700 does is provide wireless access to the network, essentially it acts solely as a wifi AP. Every other wireless device on the network is functioning fine including 3 laptops, a Blackberry and two other Android tablets ( Asus Transformers). So I know nothing is wrong with the dhcp or the AP in general. It's not a security issue as it is not failing on authentication, just on obtaining IP. So as a workaround I configured each one with a static IP and, of course, everything works fine.
One thing I noticed that seemed odd was that when I went to change the IP addr the address that was already in there, but greyed out sort of, was the wrong network for my home wifi. The phone and tablet both looked like they had a 192.168.1.0/24 address whereas my home wifi segment is 192.168.0.0/24. So maybe that had something to do with it. At the office now and both my phone and tablet have no issue connecting to our Cisco APs and getting a dhcp config from a Windows DHCP server. So pretty weird situation. I'm fine with leaving them on static config while on my home wifi network. Was just wondering if anyone else has seen this before?
Thanks
For any that might be interested. I used inSSIDer to find a less crowded channel for my 2.4 ghz band at home and both my Samsung devices are connecting and receiving ip addrs now.
