[Q] Droid X2 stuck on Obtaining Ip Address WIFI issue [SOLVED]

---

This has been plaguing me for a few days now and I just want to share the solution I found for you guys. Have you ever had this issue? Your selected wireless network has been working great for days and suddenly one day it refuses to connect anymore. I would hit connect and the phone would be stuck in a "Obtaining IP address from WIFINETWORK" "Disconnected" "Scanning" cycle and so forth. You can wait forever and the phone will never connect to wifi.

The first time this happened to me I did a hard reset. Worked like a charm, I was able to use the network again for a few days until it began happening again. I decided a reset was not the solution so I looked for an answer. I happened upon sites like this:

Where certain solutions were posted but none seemed to work for me. I decided that it definitely wasn't my router (although some said resetting your wireless router may also work sometimes).

I finally stumbled upon the answer. The solution is to use a static ip by going into to Settings>Wireless & Networks>Wi-Fi settings>Menu Click to Advanced and then check Use static IP. You must figure out these values: IP Address, Gateway, Netmask, DNS 1, DNS 2.... Luckily, it is pretty easy.

IP ADDRESS
To find this, go back and select your wifi network. Hit "Modify" and see the IP address listed. Copy that down, this is your IP Address.

GATEWAY
This is your router's IP address. You will need a computer that is connected to the network already. For Windows, run a command prompt and type ipconfig to show you the default gateway address. For Mac, go to the network preference pane in system preferences. Click advanced and go to TCP/IP tab.

NETMASK
You will find this in the previous step. Often it is 255.255.255.0.

DNS 1
Put in the same IP you found for the gateway box.

DNS 2
Same as above.

In the end it will look something like this:

IP Address: 192.168.1.107
Gateway: 192.168.1.1
Netmask: 255.255.255.0
DNS 1: 192.168.1.1
DNS 2: 192.168.1.1

Connect again and it works. No need to factory reset. Enjoy!

Update: After a few days, something in the phone's wifi settings seem to "correct" itself and your wifi will not work with this method anymore. Simply go back and disable static IP and your phone will be back to its old self again. If the symptoms appear again, you can follow these steps again.

I wonder if this will help with eclipse 2.0.3 disconnecting issues

I was having this problem with CM7 and this fixed it. Thanks!

thanks solved my problem i m so very grateful

Careful, this "fix" could be very temporary... If you set a static IP and do not configure your router to use static IPs you will at some point run into conflicting IPs if you have other devices on the network. The router is dynamically allocating IP addresses if you use a standard DHCP setup and can give your chosen IP for your phone to any device on the network, creating a situation when you cannot connect or you can connect but it does not work. If you want to use static ips on your phone with the router, you have to configure the router to understand this by disabling DHCP and setting up static IPs for all devices or by allocating fixed IP for certain MAC addresses. SO either setup both your phone and router to use a static IP or change the DHCP lease time to something other than "infinity" .

Most routers strart DHCP allocation at .100. Check with your particular routers manual. If you assign the IP less than .100 you should be fine as long as you don't assign another device with the same IP.

I'm with DigitalMD - this is a very kludgy "fix" that will lead to trouble in the future. I am coming to believe there is a consistent interoperability issue between Android and some other systems (OS X and some routers??) that leads to issues - both my GN with 4.0.4 and my JetStream with 3.1 will routinely fail to connect both to my Mac (10.7) and the routers, primarily in a couple of particular offices - maybe it's just a high-noise area (one is an older building). The devices both connect fine to my home wifi (WRT54G) and most internet cafes.

Not a good fix

This isn't really a fix for the problem. I connect to multiple wireless networks, between work and home and friend's houses, and they all have different routers. Setting a static IP is impractical, because I have to turn it on with certain networks and off with other networks, or change the static IP from one router to another.

Why does this happen? It works fine for a while, then one day it just doesn't want to take an IP address from the router. For me, it works fine at home and at my parents, but at work, it doesn't want to connect anymore. It's been connecting fine for months, then yesterday it got stuck with obtaining IP.

Setting a static IP isn't a solution; it's a cop-out. Does anybody know why this happens? Does anybody know how to fix it?

I was experiencing this from past couple of days than I just put static IP works really great for me it was a biggest headache, now past.
