[Q] wifi MAC is missing after doing factory reset - Galaxy Tab Q&A, Help & Troubleshooting

Hi everybody,
I'm having an extreme problem with the galaxy tab wi-fi. The thing is that, I bought my tab just 7 days ago and everything was fine. The only issue I got as usual like others in this forum or internet was the wifi adhoc problem.
So, I got over everything I could and found on this forum and from many others as well. I've tried the wpa-supplicant file replacement and the methods way described in this forum in all way. Finally, what I could get close was to make the connection between the tab and laptop adhoc hotspot. But no luck on getting the internet still.
Finally I thought of factory reset and doing this the main problem appeared. After doing the factory reset, it shows that the MAC address for the wifi is unavailable and so for the bluetooth as well. I am just stunt to see this and no way I can get back to my original state. So, it's currently a tab without a wifi. Please help me or guide me to the solution of this problem to recover my wifi mac address and to make connection with the ad-hoc connections.
For your note, the android version was froyo (2.2), never updated to any other. I also have the galaxy S II which runs on Gingerbread (2.3) and that doesn't have any kind of problem with adhoc networking or so. That just gets connected through connectify straightly.
Please back up me with your solution available and thanks in advance for this.

[Q] WiFi problem: stuck on "getting IP address"

I have had my Tab for 2 weeks now.
At home I had no problem to connect to my WiFi network for 1 week: then suddenly the Tab would not connect and would remain stuck on “getting IP address…”.
I changed from WPA to WEP to WPA2 PSK with no luck
But if I go to a static IP, then I have no problem to connect.
On my office “public” WiFi network, exactly the same problem: it worked for a week and then bingo stuck on “getting IP address…”. Again going to static IP solved the connection problem.
My question is: how do you delete a network from the list? It seems to me that the Tab keeps an IP address in memory and if ever that address is taken by another device, it gets stuck!
Any advice would be appreciated.
I had this exact same issue on the same day I bought my Sprint Galaxy Tab (11/14). I did a hard reset that afternoon, and I haven't experienced the issue since. I'd already had all of my apps downloaded, and settings tweaked, so hard resetting was kind of annoying. I hope this doesn't come up again.
Yep sounds familiar, my Thomson Speedtouch 780i runs on a old firmware which gives me same issue with the Tab, had to run with no security. If you decide to run with no security turn off broadcasting..or update firmware/router..
My router is quite recent and has the latest firmware.
All my toys (iPad, Dell Streak, HD2 together with 3 PCs) connect without any problem.
The Tab had no problem either for a week.
Then for unknown reason no way to connect unless using a static IP.
And as I have not found a way to delete the network in memory (short of doing a hard reset)I am stuck.
And now same problem arises with office netxork:-(
Yeah just do a factory reset in privacy settings i think

My Tab is doing the same thing now. I can't do a hard reset....is there another solution?
Ugh, I have the same issue! Had it for 2 days and all of the sudden it's stuck on Getting IP address from... Resetting to factory defaults was depressing. I wish there was another way!
It also happened to me when I was on vacation at my relatives home. The tab would work for a day or two and then be stuck at that message. I had no issues with doing a factory reset as it was still new. But then I started using the static IP trick and that worked. Now I'm back at home and I don't have this issue at all. Been using it for a week with my wifi and all is well.
Nothing was actually working: restarting the router, forgetting the network, creating the network manually, changing the authentication method, etc.
I'm sure its was an issue with the router at my relatives home, but still why was my Nexus one and Laptop connecting with no problem???
For those who are having the problem, use a static IP for the time being, you don't have to reset.

I ended up switching to Channel 1 on the router at home, and haven't had any problems since. Chose Channel 1 after running WiFi Analyzer.
having this same problem. I've messed with WEP vis WPA and tried static IP. Using a verizon fios router. any help?
Bah, it happened again! Now I really dont want to reset
Same issue here ...
I can get WIFI at Starbucks but not at home ( Open-WRT on linksys )
I wonder if it depends on SIM card being inserted?
Mine is a Verizon FioS router as well, at work. Can get on fine at home or anywhere else. My iPad had a problem here forgetting the network but I could at least reconnect. This is doing exactly like you guys.
I wouldn't even care that much except when I'm inside the office I can only pull in Edge data. Ugh.
I had to change wireless settings on my Linksys - most changes were to disable some fanny things like "afterburner" - and setup wap2 for security to have a stable wifi.
I've had the same problem with my TMobile Galaxy Tab. All I do is to turn off Wifi in the Settings app, then turn it on again. I am usually able to snarf an IP address straight away after that.
It also helps to just turn the device on and then off again. it boots so fast that it isn't too annoying.
I had similar problem at home. My DHCP server had wrong time set. After setting the time on DHCP server correctly everything is back to normal.
i hav a tab on tmobile love it not sure if i had the same issuse as u guys tho the issuse i had was it would work without any problems im talkin about wifi then the next day the wifi doesnt want to lock onto the wifi it would search then drop to start serchin again , now wat i learned is sum apps require wifi to work because high data at the same time it changes sumthing in ur wifi settings after using the app the first time which would require u to master reset the device to resolve the issue the program that was doin it for me was frostwire
same here
my version of the same problem appeared when i changed the static IP of my home router (AVM Fritz!Box 7170). before that i always got a dynamic IP through DHCP on my galaxy tab.
After changing the router IP i only could connect with a static IP.
if i use a different WIFI network instead, DHCP is working as expected.
in my opinion the problem is with the firmware storing the network settings and with no possibility of deleting it completely. a hard reset cannot be the solution...
does anybody of you know if this problem occurs on other froyo-based devices also? is there a way of deleting network settings in a working way?
Had the same problem, EU TAB white Stock 2.2 rooted spot connecting to my main Wifi but connects to 3 or 4 other dhcp APs.
Have a htc Desire whit stock 2.2 + rooted and never had that problem.
In the end i hardreset Tab and no problems 1week and counting.
EDIT
FUuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
Happen again... im not going to hardreset again, im looking for a more permanent solution
Had the same problem. I have the Verizon FIOS router. The solution is actually easy. Just drain the battery of the Tab. Charge it to full and turn the Tab on. I think the Tab really "forgets" the old network after this kind of restart. No need to reset your Tab to the factory settings.

[Q] Internet connection problem

Hello everybody!
This is my first log in here, because I got a new Nexus One this weekend and I heard that your forum is one of the best about it.
So, I have a problem with the internet connection. My Nexus One is connected (the internet connection is exellent and I use it now with my laptop) but it just doesn't works. When I try to use the browser application or an another app, which needs internet connection, the application says that I have a problem with the internet and I can't use it. Any ideas ? Thanks!
Does it do this on all routers or just your home router if it's just on your home router?
It does this on all routers. Everything is okay now. It works fine. But that happens periodically and I don't know what's wrong with my phone. Now I'm trying to flash my phone from 2.2 to 2.3 and we'll see what will happens with it.
Ok well if you need any help with flashing the update (like if you're on a carrier tweaked ROM) then just ask.

Lets try this:
Check whether your laptop can get an IP from your wifi.
I. YES
- Turn on wifi on your note.
- Go to Applications -> Settings -> Wifi settings.
- Look down at Wifi network.
- Touch into the name of your wifi then choose "Forget network".
- Turn off wifi on your note.
- Turn it on again.
- Enter the key and see what's happen.
II. NO
- Check your router configuration.
If you hav have enabled mac protection on router, reset it.

Hi,
Laptops x3 and other peoples phones can get onto WiFi ok, both at work and at home, my Note Will connect ok to the BTFON / BTOpenzone (off of the same routers) with no problems again both at work and at home. We have changed nothing with the routers (BTHome hub 2 and BTBusiness hub at work).
Can you advise what to check with the router as all seems to be in order for all other WiFi devices, it's just my Note that is having a fit and wont connect?
Many Thanks

Hi, Re mac protection, the routers auto set up and I am unaware how to check re mac protection. I cant understand why has my Note decided to stop connecting out of the blue?
I have similar issues.
I have setup a WIFI hotspot and all my non-Android devices can login without any issues (Notebooks x2, iphone3, iphone4, ipad), however my Note and my Blade (all running 2.3.6) and an Acer A500 Tablet (running Android 3.1) cannot connect.
The android devices see the hotspot and will attempt to get an IP, but most of the time will not succeed.
Any suggestions?
I'm having the same problem with the "stuck at obtaning IP address" problem.
Just got my Note 2 weeks ago and am still not able to connect to the internet using wifi.
I can't connect to my home wifi nor starbucks nor any other public wifi. When i use static address, i was able to connect to my home wifi BUT could not use the internet. I really do not know what to do...PLEASE HELP!!!
I too have experienced this. Running stock 2.3.6 + root. happened with lots of different routers. Usually solved with power cycling router & note wifi. Very annoying.
I think (personally), it has nothing to do with the Note at all, BUT on most samsung smartphones...
I read somewhere that Sammy's phones have a weak side in detecting and connecting to any wifi device...
I personally tested this also with my Note, side by side with my friend's Nokia, a Blackberry and a Galaxy Nexus as well.. both Samsung phones stucked at "Obtaining IP address..." for some time, while the two phones (Nokia and the blackberry) connected thru wifi with ease... no problems at all..
I have same problem periodically at my sister's house, especially when a lot of other mobile devices using the router. If you google the issue there are many with same problem.
Simplest way to solve it for me has been to unplug & then plug the router back in. Rather annoying.
I had same prob with my galaxy tab... Forgetting a network won't help..
Nor there is fault of router...
Google this problem you will find results with solutions for xda only... (did the same but don't remember the link)
Al t bst!!

[Solved] Wifi - no internet from my router

Hi
I just received a new note from rma, everything looked to be working fine, except wifi internet.
With my previous note i had no problems, connected to my router and had internet through it.
With this new note it connects to the router without any hiccups, i can even use the phone to move my computer's mouse over wifi, but i don't have internet access on the phone.
I installed Gerret's miui rom as soon as i took the phone out of the box so i'm not even sure if it also had the problem with the original rom but i did turn it on with the original rom and i think it did not have.
Anyway, i tried to give a static ip to the phone on the router settings (a TP Link TL-WR1043ND), i tried changing the wifi channel, tried it with wpa and open. It always connects to the router, but i never have internet...
I have another android phone and i put a mobile card in it and turned on the hotspot on that phone, connected the note to that phone through wifi and i do get internet on the note that way ... so it looks it is a problem with my router and this newer note version. :/
Any ideas to fix it?
Thanks
Ok, got it working after updating the router's firmware. xD

[Q] Cable modem/router: Wifi signal ok but no connection

Hi guys,
My phone: Samsung Galaxy S3, GT-I9305, Android 4.1.2
I changed the ISP (Germany: To Unitymedia) and are now supposed to use a cable modem which as well serves as wifi router. My hardware is TC7200 (Technicolor).
After setting up everything, the wifi connection to Win 7 laptop and Apple iPhone/iPad is working fine (also LAN connection to laptop of course).
The S3 showed a funny behavior: It is possible to establish a wifi connection and it gets IP address assigned. Default gateway, DNS server looks all fine. However, this is only the wifi signal but not an internet connection. It is not possible to reach any website.
The strange thing: If the google site is cached (from a different connection and then switching back to this problematic one) I can run a google search and get results displayed. However, it is not possible to open any websites displayed as results here.
I tried several things based on suggestions in the net, like restarting the s§, using static IP address, changing wifi ports, disabling wifi encryption completely, restart the router, factory reset the modem/router. Finally I performed a factory data reset for the S3 but this as well, like all other things, did not help. The phone was never rooted until before yesterdays factory reset, because I wanted to use Titanium Backup which requires root rights.
Of course, in all other wifi networks so far, this S3 works absolutely fine!
I am not sure if this matters at all, but with the new ISP I got an IPv6 IP address while before I had IPv4.
To be honest, it might simply be a hardware problem which has to be fixed by Firmware upgrade by ISP. This problem is sort of known to them and when I called in they promised a firmware update in November. But anyway, it would be interesting to understand more about it and usually there is a solution for everything Nevertheless, I couldn't find a solution in any forum yet.
Any suggestions / ideas welcome.
Thanks!
EDIT:
Post already moved.
Reads like wrong settings more than hardware .
WiFi is kernel you can flash a kernel .
But i would reboot router and phone then set up wifi with no security first .
