Default 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 - or

Gateway - (I chose since that's my router address)

NPL - 24

Netmask - (I could not find this option)

DNS 1 - or (I had the latter by default and let it stay)

DNS 2 -

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

Thumbs up 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
