[Galaxy Note II Q&A, Help & Troubleshooting] Sacrin82:
Think found a problem, but not a fix

The post originally posted for problem connecting to WiFi and obtaining IP address.

My previous post provided information about efforts I tried, but no luck.

Recently I managed to find the same device with the same kernel (alittle older) and that device had no issues. My device is from T-Mobile, another one with no subscription. Probably operator doing something with kernels.

For me I found the problem, but not a fix.

After installing dhcp server I was able to see strange requests coming from my phone. Searching on the internet found a good site providing description of my problem: "Behaivior A", but can't paste normal link (Junior user). Try to follow the link:

"www . net . princeton . edu / android/android-rapidly-repeats-dhcp-transactions-many-times-33590 . html"

Here are the logs from my dhcp server before it got connected. As you see device sends DHCPDISCOVER rapidly and ignoring DHCPOFFER coming from DHCP server, exactly as per description in the link above.

I wonder who can fix it?
