[Q] Tab won't find my wi-fi - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

I seem to be having some problems with my tab gray 16 gb wifi version.
When i started it for the first time it could not find my wifi, i went ahead with setup and when i was finished i looked into wifi settings and it had found my router.
A few days went by and all of a sudden i was connected to the router but had no internet connection, I checked my computer which was connected by wire and it had internet connection. I then tried to switch wifi on and off on the tab and since then i cannot find my router.
I've tried rebooting both router and tab and it has not resolved the problem. Anyone else experiencing these issues? Any solutions? I thank you all in advance.
btw the router is a D-link dir-655

Unplug the router and plug it back in. I have experience this issue as well. My desktop was able to connect to the Internet. But my laptop won't connect through wireless. Not even my wireless printer. I unplugged it and plugged it back in, and it works fine. Sometimes, it's other way round.

I have the same router and I don't have any problems connecting. I did have many problems with my OG Droid phone connecting though, until I switched from WEP to WPA encryption.
Can you see the router on your Tab, but it just won't connect? Or is it not visible at all?

I have tried unplugging the router leaving it unplugged for 30 sexonds or so and then plugging it back in, no luck. And no I cant even see the router, I see lots of routers but not mine, I can connect to my phone using mobile access point but just not my router

Does your router use a hidden SSID?

This might sound funny, but do you have anything else connected to the WiFi? My router sometimes does this same exact thing and it happens to do with the traffic going through it. It happens alot when I'm using my laptop and my Xbox 360 and I turn off my Xbox for some reason. The way that I've always found that fixes it, is by rebooting all my connected devices along with rebooting my router. It's as if their is a conflict with the connections that make it not work.

No hidden SSID and at the moment nothing is connected to my router wireless
edit: Solution! logged in to my router switch of wi-fi, turned it back on, enabled wpa2 security and there it was right on my tab, welcome back old friend

I had the same problem, but solved it by changing locale setting on my router from Czech Republic (where I live) to USA.

figure out how many devices are connected to your router. My router can hold only five devices at a time. Also change the channel in your router settings.

good to know problem is solved

[Q] Wi-Fi not working propely

Hallo everyone,
on Friday I bought a new Folio 100. Unfortunately it seems that the Wi-Fi doesn't work: the tablet connects itself only after I turn off and on my wireless routing.
If I disconnect the tablet (or the connection is lost) and then I try to connect it again, I have no chances The Wi-Fi connection cannot be established. Same if I turn on the Folio and try to connect it without a previous off-on of the router.
I have a WEP 64 Bit encryption. I tried to change it to WPA-TSK but the problem remain the same. I tried to connect to my Galaxy S using WPS2-PSK no way. The folio connects itself only after a restart of the router or with not protected nets.
I tried to install the Dexter mod 1.3a, with no results. Now I have the original FW 2.2.5.0053 back on (and the problem remains).
There is something I do wrong or I can still try or the tablet is definitely defective?
Please help me!
Thanks a lot in advance!!
Paolo
I had a similar problem: my WiFi network was seen as out of range by the tablet WiFi manager. And whenever I put the Folio in sleep mode, it lost the connection.
So, I changed the WiFi policy (in WiFi advanced settings: press menu button when on the WiFi configuration page, and choose advanced settings) to never turn off.
The tablet still has some difficulties to catch the network at startup (usually, I have to wait like 2 minutes), but now it keeps it.
Hope it helps...
Hello SinDeus,
thanks a lot for your advice, I've already tried this setting, but in my bedroom I've a bad signal and from time to time the connection get lost... and you can understand that it is really annoying to stand uphalf asleep to reset the modem. )
Anyway for the moment I've solved the problem exchanging my Belkin modem with a Zyxel of a friend of mine. The connection process is still quite slow, but at least it works without requiring a router restart.
Bye Paolo.
mine still not working...keeps on connecting/disconnecting......giving up soon...btw am using foliomod 1.3...even before when am using the stock rom..its so freaking hard to connect to my belkin router...only a few times tht i successfully get connected...help please!!!!
Hallo Neworder,
I had to exchange my router, the only way I was able to conect with belkin was restarting it.
I've also tried with static IP adress and changing the encoding type (WEP, WAP-TSK etc.) but the results was always the same. Even with the new modem the process isn't that smooth!
Quite annoying.
Sorry that I can't help you further.
the thing is if am connecting the folio to wifi connections in cafes/shops/eateries,no problem...fast and painless.
time to change modem router?
btw pademat which model of belkin u r using?am using a belkin 54g.
and ur new modem?zyxel which model?

[Q] Can't Connect to WiFi

Hi just received my GTablet and have installed ClockworkMod v08. Next, I am attempting to install the TNT Lite Rom but I am having trouble connecting to my home router.
The response I keep getting when trying to connect is to the point of "Obtaining IP address.." then it disconnects. I am sure it's not the wireless router but just to be eliminate possibilities, I've even switched off all the security with connect to the router, but the sames results. It keeps trying to re-connect. I can easily connect with my other PCs and printers.
Any ideas? Thanks in advance.
Hello there,
did you ever solve your wifi problem, I am currently running the latest TnTlite, and this just started happening to me as well. It just hangs in Obtaining Ip then it disconnects.... I have never had this problem before in fact was online on the tab last night, now it seems i cannot connect... I will see if I can connect in another location hope nothing happened to the Tab..... BTW I tried restarting as what was suggested but that did nothing for me also....
Are you broadcasting your SSID?
Can you take the tablet somewhere else and try connecting at a Star Bucks, or a library, or something. See if it connects ok there?
Also, if it doesn't connect anywhere. Try flashing a different ROM to see if it is just that one.
I've had the same problem. I do not seem to be able to connect to any wifi that is encrypted with WPA. At work, we are WPA and I cannot connect at all. At home, I have WEP and can connect. I thought it might be something with the wifi settings on the tab, and have searched and searched and cannot find anthing.
By the way, this is my third tab and none of them could connect to a WPA encrypted router. The first two I returned as defective. IF there is an answer, I would love to hear about it.
Also, this is my first android device. I have been messing with Windows phones for a long time...thanks to the great people on this site.
Sorry to hear about your wifi problems. Just to let you know my experiences, I've (in the week I've owned my tablet) run TnT, VegaN and cyanogen (latest of each) and have never had a problem connecting to my home wifi - I do not broadcast my SSID at all and use WPA2/PSK encryption. You both mention WPA - can either of you try WPA2/PSK?
But on saying all of that, if you can't even connect to your wifi point without any security involved, it sounds either:
1) Hardware - faulty tablet but you said you're on your third so that sounds unlikely. Remember, while the tablet supports wifi G/N it does so over 2.4Ghz so if you have a router that only does 5Ghz or is set to work exclusively over 5Ghz, your router will not see your tablet
2) Software related - Have you reflashed your kernel at all? Did you possibly install a kernel (not rom) that does not have wifi drivers installed or something similar?
I hope something above might help you....
I was never able to connect to the wireless router. I shut all the security off, reset the router, rebooted the tablet but still the same results, "obtaining IP address" then it fails and tries again. I could connect to my neighbors Linksys so I know the tablet wifi is ok. I also so know that the router was ok since it had been serving my other PCs & printers for a number of years. It just wouldn't connect to each other.
The problem still persists.

You didn't answer in your response above, is your router a 5Ghz router or 2.4Ghz? Could the frequency of your router be causing your problem here? Remember the tab only supports 2.4Ghz frequencies
1. if your tablet can connect to your neighbor's router, then problem lies between your router and the tablet.
2. is your router a linksys? what wireless router are you trying to use?
3. are you using mac address filtering? is dchp enabled on the router or by some sort of home server?
4. your tablet can see your router, but for some reaon they cant agree on how to talk to each other. i'm on a linksys wrt54gsv4 and havent had a problem, not with default settings or wpa2 or mac filtering or the custom firmware i eventually installed on it (ddwrt), tomato)

You are ATTEMPTING to install TnT ROM? You dont need the Internet connection, just sideload it then install. Am i Right?
Then after you install the TnT rom, sideload also the Kernel TnT base with wifi fix.

Hope this will solve your problem.
Good luck

I have an older Microsoft 2.4Ghz B/G wireless Router. I'll try to sideload the Kernel TNT base with the WiFi fix.
Thanks for the tips.
Since the original posting I have got TNT Lite installed (using my neighbors router)

Something else occurs to me out of pure ignorance. I'm not sure how Android stores profile information. But I know with both mac and windows I've had occasion where "forgetting" the network and letting the device rediscover it has solved problems.
It sounds like you've been down that road already. However, it does bear asking. It's the more obvious things we often forget to consider.
Well it looked like the tablet needed to be reset a couple of times as i was just online with it... now the tab just froze, shut off and now i cannot turn it on... off to another thread to see what to do now... god i hope this thing is not bricked....any suggestions on what is a good thread would be appreciated... off i go.......
edit: found a thread now to find the internal reset button. thanks to all at xda....

Try to hold the power button for a long time and maybe it may turn back on. Before doing your last resort (disecting the tablet).
I had a problem with my wifi going into loops when I first got the unit. It would show it connecting/disconnecting/connecting/etc as described in the first post.
I had another router (both the same makes - Linksys WRT54G but different model numbers) so I tested the other router and I connected fine. I haven't gone back to test the first router yet and I am using the 2nd one.
The router I couldn't connect to has DD-WRT micro on it, and I haven't had problems connecting other wireless devices to. The one that is working fine with the g-tablet now has Tomato on it (it is a lower version number which supported Tomato).
Too bizarre... I now have this problem.
I received my gtablet today and installed clockwork mod recovery and vegan-tab ginger RC 1. Or, essentially, I followed the instructions here and got everything working. http://forum.xda-developers.com/showthread.php?t=865245
Wifi worked fine until the evening. Wifi is on, and in the settings under the SSID of my wifi network, it says Obtaining IP address for a minute until it says Disabled, network in range. I've done some common trouble shooting, like restarting, turning wifi off and on, forgetting the network and reentering password. That didn't work. My cell phone has a mobile hotspot feature and the gtablet CAN join that. I wonder what gives... I hope someone can help.
(This could be just coincidence, but it's about when I powered up my desktop computer. The desktop connects to the internet through a DMZ router that has a wired connection to the wifi router in another room. The desktop is now off and the gtablet still has this problem.)
Ok. Resetting my router fixed it. I never thought that my router could just "dislike" one particular device. I thought for sure something had to be wrong with the device. Forgive my ignorance!
G Tablet Wifi
I do not transmit my SSID and this has never been a problem with any of our laptops or netbooks. When I first received my G Tab and tried to connect to my network, even though I had entered the SSID and Passphrase correctly, it still would not connect. As soon as I set my wireless router to transmit the SSID the G Tab connected without any problems.
This is the first time I've encountered a problem of this nature. Comments?
This is what worked for me. I posted this in a similar thread as well.
Hey, I had WiFi connection issues too. I just got a Viewsonic G-Tablet with the Android 3.0 OS and have a D-Link DI-524 wireless router. It could see router and would try to connect, but would cycle and never connect. I could try to connect to other available networks in the area. It connected fine to an unsecure network, and when I tired to connect to secure networks there was a place where I could enter a network key/password. However, I noticed this option was not available on my network when I tried to connect. I reset my router which did not help. I then chose the option to add a network on the tab. This worked!! I was able to enter the key from the add a network option. I then told the "bad" connection to be forgotten. Hope this helps someone else, as I had looked on the internet for awhile for an answer. I was about to buy a new wireless router too!! Oh, I am using WEP too.
edit: ok when I power my tablet back on the same issue was happening. This time I could enter a network and the cycling still contiuned. I even forgot and re-entered the network. The fix this time was to reboot the tab. However, my internet has been acting up lately so IDK.

Wifi not working?

I can't seem to connect to wifi. The phone keeps cycling between connecting, Obtaining IP address and Disconnected.
Anyone else having this problem? Any advice?
Are you connecting to a WPA enabled router? I've had issues on my Droid with certain routers (D-Link for one)... If I switch the router to WEP, it will connect fine.
For a phone to not support WPA is pretty lame. I picked up the TB today but I am at work. Hopefully it will connect to my home wifi network, I will update you on my results!
Had a similar problem on one of my TBolts...power cycle resolved it.
I can log onto my WPA network with no issues. Maybe bad password?
Well, I do use WEP and it will not connect. I turned off WEP just to see and it connects fine when I leave the network open.

Mine seems to be working fine, just connected to home network - I don't get a wireless icon up in the notification bar, but it goes green on my toggle.

[Q] connecting to a non broadcasting wifi signal

So it seems that there is no way to connect to a non broadcasting wifi network in any of the current froyo roms. Anyone got any ideas on how to resolve this?
I have tried hidden wifi enabler and even added it separately, but it just says out of range when its sitting right next to the wireless router. With broadcasting on it connects with no problems.

I've done it in Vegan... what encryption are you using? I know there are issues with WEP...
using wpa2 I heard rumors that tkip doesnt work with it. This correct?
I got mine to connect running stock and TNT 4.4 but it wasn't easy. I intially went into wifi setting and "add a network" typed in the SSID (not being broadcast) and password (WPA2/TKIP) and it would find the network but not connect. I did some searches and found various suggestion but none worked.
After a lot of failed attempts I got frustrated and turned off wifi on the tablet and then turned it back and suddenly it connected with no problems. It may have been a one off thing but couldn't hurt to try it.

Ill give this a try and see what happens. But I am not getting my hopes up.
Just out of curiosity.....
What's the point of connecting to non-broadcasting router?
It's like turning on WiFi in the middle of desert?
JMO.....
turn on ssid bdcst. connect then turn bdcst off.

If your wireless router doesn't broadcast it's SSID, others can not attempt to access it.
My Stock 3588 connects fine
I have a non broadcasting router in my home and stock 3588 on my gtab. Did the connection once when I bought the tab and it has been connecting just fine for couple months now!

So not even close to true
Using a non-broadcast SSID as a security measure is probably the weakest (well...next to no encryption at all) method available.

Using a Linux PC, I can see ALL available wireless APs with this command:
Code:
iwlist wlan0 scan
Hiding the SSID is not even considered to be a security option, it is that poor. Save yourself some trouble and let it broadcast the SSID.

[Q] Loosing wifi network connection after a while.

I am using SHOStock 3 3.0.2 on my i777.
I just changed my router (TP-LINK TL-WDR4300 with DD-WRT running) and strange thing began happening.
When I connect my phone to Wi-Fi everything works as usual, then after a while (maybe about an hour?) no connection to network at all.
WiFi signal is strong, has IP Address assigned, router sees the device. But, cannot ping in or out. No connection to network at all.
If I disconnect from WiFi and connect again, it works for a while, then same thing happens again.
No other WiFi device in my home is having that problem.
Any ideas what might be the cause, anything I can try?

I'd do a factory reset first to isolate whether it's your phone or your router causing the problem.
