[Q] I cannot get my android tablet ( Viewsonic G) to connect

I cannot get my android tablet ( Viewsonic G) to connect to my Microsoft router. When trying to connect to the Microsoft router the tablet reports "connecting", "obtaining IP address from MSHOME", "disconnecting" and it starts all over again.
This happens alot to me too when trying to connect to open connections. IE free public connections. It connects to my router instantly though.
ROM? Router settings? Can't help without proper info...
i have the gtablet with android 2.2 and bootloader 1.1 3588. the original problem was that some applications were forced to close and the stock calendar closes when i needed to add an event. i was advised to install wcm and do the repartition which i did yesterday. the calendar is now working but i got a far more serious problem, exactly what ktant1 has described. the tablet is finding the router but not able to get an ip address from the router, regardless of the brand. prior to the repartition and wcm i had no problem connecting.. any idea or fix...thanks for all efforts
i apologize if there is any other thread with the same subject ...i am just new to this and did not search the whole forum..
finally my problem is solved... i am sure it is not everyone's solution, but it worked for me...
i turned my router on and turn it on back...the first time nothing happened.. on the second try my tablet connected like a miracle.. go figure

[Q]Android 2.3.x WIFI issue

Hello everyone
okay, i've been with a really anoying problem since the 2.3.x updates on android (Samsung Galaxy Gio in my case). The problem is that everytime I try to connect to the network, I stay some seconds with good connection and suddently the router just rebots himself. Tryed already changing some router settings (by the way my router is an Zyxel P-660W-Tx v3), setting the phone to factory, deleting apps and I always get the same result. I tryed to contact the Zyxel company but with no sucess until now. I know there's gotta be another fix than just have to buy a new router so it would be great if someone could help me out. Because this thing is freaking me out already.
Cumpliments,
Deviantor.

Wi - Fi Problems, obtaining wrong IP [SOLVED]

Attention!!! I found a fix for getting wrong IP using your router!!!This should help you if internet worked at first day on phone or sometimes works and sometimes not after reconects. This thread i created is about my routers not working with SG3 and other devices. Router fails to assign right IP for my SG3. Example: 192.168.0.100-199(last digit from 100 to 199) should be IP in that range but phone aquires 192.168.1.6 or 192.168.1.8 and it can't get internet acces! I could connect but not surf the internet. To make device get always same IP and most importantly get GOOD IP wich would not be broken and you could surf internet. You just need to reserve IP in router's network settings. This fixed my problem instantly!!!
Thank me if it worked for you!!
----------------------------------------------------------------------------------------------------
Everything below is history!!
Pure stock, not rooted SG3 international version.
I have strange wifi problem. We have 2 routers. One is main(dlink) it was working fine for 5 days and sudenly my SG3 can't connect to internet. I saw that my SG3 is aquiring wrong IP 192.168.1.8 instead of IP192.168.0.(range of 99- 199) so it won't get connected to internet, but connection to router is good. Tried 2nd(linksys) not main router and it works, i can connect to internet (aquires right IP 192.168.0.138) something like that in right range from 99 to 199. First tried wifi fixers. Didn't work. Then tried factory reset didn't help too. Then hard reset from recovery with data wipe ( correct me if that isn't hard reset). That helped, but not 100%. Now i can connect. To main (dlink) router with right IP IP192.168.0.(range of 99- 199) and internet works, but tried with 2nd(linksys) and now problem has transfered to that 2nd router. I only can ask you. Why? What socery is this? Maybe custom rom i install from stock would fix this. Or i need to fix my problem without roming first? Strange.

Update: i lol right now. I went with my SG3 to googleplay via (main dlink router) downloaded angry birds seasons to see download speed. Speed was okay, played few mins. Tried to go to store again. Internet was gone. Internet works fine on my pc but on phone throught wifi not. And changed IP from 192.68.0.(last digit range 99 - 199 ) to 192.68.1.8. Now both routers have 192.68.1.8 IP as i connect to them with my SG3. Connection is strong but internet does not work, because of that freaky IP. I don't imagine how to fix this. My only thought is to flash my SG3 to custom ROM, because other devices works fine with these 2 routers.
So i flashed custom rom and it worked for a while. I guess because i did data wipe/factory reset. I thought i have solved the problem. Recently i installed FoxHound Rom wich is absolutely briliant. Then getting started app asked me to find wifi network. I sat near my router and... it again aquired wrong IP --->>> 192.168.1.8 <<<--- INSTEAD of 192.168.0.( from range 99 to 199). I i don't know what to do next! HELP ME PLEASE! :/
Our other device Galaxy Note works fine as ipad works fine too with those 2 routers.. But not SG3. Arrggh..

I dont know if your router supports it; assign your phone a static IP.

Now i have flashed other custom rom and SG3 aquires right IP. For now. Internet works fine. Will report later. Any advices appreciated.
-----------------------------------------------------------
Update: found this thread http://www.dslreports.com/forum/r22...-wireless-devices-aquire-the-wrong-IP-address.
He says:
"Everything connects to the router but getting internet working is only accomplished by manually changing the settings to those described above."
Maybe that's because my SG3 can act as modem too? Can galaxy note 4.0.4 act as modem or iphone4?
Unfortunately problem back again. Browsed internet for few min and got wrong IP as i came 3rd time to connect to wifi dlin router. Then i tried another router linksys and got instantly bad IP by connecting to it too. What to do now?!? It's definitely something wrong with my SG3. Do i need to reflash to original, reset counter and take it to warranty post?
Or maybe there is else i can do? Help!

why dont you use the [1 to 99] host byte range? I know range doesnt really matter but if your phone wants to connect to the lower part, why not change that? Plus, did you try giving your phone a static IP address? thats the first thing I would do
I tried doing static IP on my phone and I think I did it wrong. Now I have flashed again I didn't connect to my main dlink router firstly after I flashed new rom, instead I connected to 2nd Linksys. Downloaded 300mb game and few more apps from googleplay, installed, restarted, reconnected and it still works. Will report later how it's going.
Sent from my GT-I9300 using xda premium
All those few days i was connected to 2nd linksys router. So it worked flawlessly until today when i tried to connect to main router dlink. First time i connected today it worked fine. Second time i got that EPIC FAIL IP 192.168.1.6 now. What the F***?! I resetted that router like 5 times to zero and reentered ips. All other devices works fine with it. Why not my SG3?!?! And my computer threw strange internet connection error but it wasn't affected by it. Internet works on my computer as it should. Error was about double ip. It said that other computer in the same network had the same ip. But it works fine after that error. I'm carring my SG3 to warranty post. I don't know any other options.
Edit: After 5 min tried to connect. It works now again just by reconnecting. Previously it didn't work that way. If it stuck, it was always stuck with that ip even if i did "'forget network" then "wifi off" then phone restart and wait some time. It could only work for some time if i did hard reset. Will see what happens next.
After another 5 min i tried reconecting to 2nd linksys router and now it has wrong ip 192.168.1.6 (not 8 at the end). But i get good in on main dlink router now! So main working and 2nd - not. Wtf... So this problem isn't caused by main router dlink. I now really believe that my SG3 has something wrong. I i will lose my connection again (can connect, but no internet), i will take phone to service.

if you somehow get your phone to connect to the internet again. Just go to the router's configuration window and increase the lease time to max (say 1000hours). That way, your device will get the same IP for at least 1000hours

What's point of doing this if i go to other place and same thing happens. I will increase time there too or smth? I need to fix roots of the problem. Other devices works fine, but not SG3. Do not know.. Will installs few new roms and take it to service. Internet works now with main Dlink router but no linksys (other connected after main). I first thought it can be main router only. I thought when main locks with bad ip so other router gets bad ip too, but i was wrong. So no point in fixing routers, because if i go to anywhere else and there my SG3 lock with bad ip what then i should do? That's the point
This time i tried onother samsung galaxy s3 wich is not mine. Gues what. It bugged the same way. LOL. But somehow unbugged to correct ip after 5min when i did reconnect on that phone. Same thing happenned to mine with new rom. I jst installed new rom on mine and instantly as tried connecting got wrong ip again. But after 5mins~ turned off wifi and back on and it started to work again. Same s*it with both SGS3. I gues that's samsung fail with wifi. Wich cause with some routers to work wrong. And again all other devices have no problems with these router wich have SGS3s. I think i will have to live with it or buy other router.

So router with my sg3 worked for some time for few day and locked again. BUT FINALLY I FOUND HOW TO FIX THIS PERMANENTALY!!! YES!!!
To make device get always same IP and most importantly get GOOD IP wich would not be broken and you could surf internet. You just need to reverse IP in router's network settings. This fixed my problem instantly!!!
Reverse IP, what does that mean?

Hello,
I am having wifi problems with SG3. Can you please explain what you mean by reversing IP in router's network settings?
Example: 192.168.????
Thanks, I hope someone sees this I know this is an old thread.

My router hates my phone? Or my phone hates my router?

Ok, so here's the deal.. I have a DLink DIR-300 router... Ever since I moved to ICS (stock and rooted) on my Galaxy S2, I always have some difficulty to connect my phone to the router...
I get "authentication error" or simply try to connect but then stops trying.
There are only 2 ways to fix this:
1-) Forget the network and turn WiFi off during some minutes.... Then turn it on again and reenter password
2-) Reboot my router
This only happens with this router (which of course drives you to think that's the source of the problem) but the weird thing is that my two brothers also have a Galaxy S2 and have no problems (using different roms)
Any idea of what might be happening or how to solve this once and for all? Additional data of my phone:
http://img201.imageshack.us/img201/3259/screenshot2012120720094.png
Make a nandroid backup of your current setup & try one of the roms your brothers are using & see if it fixes the problem. Could be an issue with the WiFi drivers in the particular stock rom you're using not playing nice with the router.
If it's OK for you using one of those roms but you really want to stay on stock, keep trying stock roms until you find one that doesn't have the problem.
They're the things I'd try if I were facing that problem. A router firmware upgrade might help as well, but given only one phone out of three is having problems, I'd try the above first.
Could it be that one of your brothers blocked you on the router?
There may be a limited set on how many wireless connections your router may be set with and yours has just went over the limit.
You could try using a manual IP, Gateway & DNS rather than DHCP settings that the router would give you.

I am sorry to let you know that you purchased a FAKE phone.
Interesting thing about MAC address to know:
00:08:22 - (the first 6 characters) is the Producers ID , it is unique to the producing company
xx:xx:xx - (the last 6 characters) is the Unique ID (or it should be).
If you type in Google "MAC address 00:08:22" you will find out that your device was made by InproCom , whereas at original Samsung it will Say "Samsung".
I found out this on the hard way, because my girlfriend bought a FAKE samsung Galaxy S3 Mini from Amazon.
I have the same problem, mine is a tablet, and every time i connect it to my wifi connection, the Mac Address is changing like if is dinamic IP. How can be possible this??? Is there a solution to have a static Mac Address???
Thank you!!!
