Hidden SSID

WTF!! Anyone know hot to get the tablet to connect to a network with SSID hidden. Tried 3 routers, no deal. Running vegan 5.1, would swith back to TNT if necessary.
Thanks.

I had a similar issue. I have two routers: The westell, it connected to no worries. The Cisco/Linksys I couldn't connect to to save my life. As soon as I let the ssid broadcast, it picked it up and connected. I can even re-hide it again, and it will connect.
I've tried a few ROM's on my Incredible, and the same thing. It connects to the Westell, no worries. But I have to broadcast the SSID for the phone to connect to the Linksys. It turns out Android is somewhat well-known for this. and I believe it to be a system issue, not specific to any ROM or branch.
In reality though, NOT broadcasting the SSID doesn't add much in the way of privacy. A script-kiddie with a WinMo 5 fone can find and connect to them. I used to use my Wizzie to find and connect to WiFi networks when I traveled. Just make sure you are using a secure connection like WPA2 or something.

Tell me about it it drives me insane!!! I'm using a dlink dsl-2740b with/ without MAC filter and i can't get it to find my hidden SSID.
did the kernel mod 2.6.32.28 - from pershoot still no go. Anyone else found a fix?

I'm running an old Linksys WRT54v1.1 with DD-WRT installed...
Non-Broadcast SSID, MAC Filtering, WPA2 -- no issues...
Worked for me right away....on all ROMs (so far) -- Stock, TnTLite, & Vegan...My phone has Cyanogenmod so I'd assume it will work as well...
I'd highly recommend DD-WRT as a new firmware for your Cisco/Linksys if it is a supported model...

I know it's totally not the point of this post but, exactly.
It in fact creates more problems than it does any type of good on any level at all because it makes it more trouble for you, the user to connect to your own network. Some chipsets have issues connecting to hidden SSIDs as well, as shows with the Tablet. Phones can have the problem too. Computers less so just because of the detailed configurations of the software.
You don't even have to be a script kiddie or hacker, there are easily downloaded, well known tools that show hidden SSIDs, along with mac addresses of any and all routers and also which sniff wifi signals. So pretty much anyone that knows more than how to check emails can get into your network if they need/want to and you're not using WEP. WEP is of course only a step up and still simple to get into with just that much more effort (not much, at all).
In these days and times in terms of privacy, if you're not at the very least using WPA with AES then just go ahead and leave it open.

[Q] NS WiFi Problem - Obtaining IP Address

First of all may I say I have searched for this problem on google, as well as xda forum. I did find several threads about this problem, but none of the solutions presented appear to be my case.
So, basically the problem is: I cannot connect to my home router, a Linksys WRT300N N-router. I could not connect with a N1, HTC Desire, nor with my actual NS. My previous Galaxy S was connecting fine though. I'm talking here about stock ROM, no rooting, no custom kernel etc. Also, using static IP address works like a charm, but then WiFi cannot be used on other outside routers, since Static Ip setting is not setup PER router, but rather per WiFi connection, meaning the phone will try to use the static IP defined for any WiFi I run into.
From My experience, it seems it could be related to wireless N router as opposed to b/g. This happened since I replaced my router with the actual one. Ever since this happened, my phone would not connect to my router. Also, this problem seems to be presentfor any N-router, since I cannot connect to WiFi in other locations as well (which might have N-routers as well).
Assuming that it is a problem with N-routers, I don't understand why the Galaxy S would connect, but NS not, since they are almost the same hw.
Does anyone have a clue on this? But please skip solutions like reset router, reset phone, reset modem, use different ROM etc. I am talking stock ROM for all the examples above.
Thanks.

I use my NS with three 802.11N routers without issue (D-Link, Belkin and Netgear).
Have you checked if MAC filtering on the router is active? What security mode are you using? Who makes yr router and does it have latest fw?

Just seen you use Linksys, I have a wag160n and I find it unsusable on terms of wifi, dreadful hardware, despite the parent company being Cisco
Check Linksys forums for problems.
Try another router for whether it's that or phone at fault.

MAC filtering is disabled, I've checked it. Security is, on the router, PSK-Personal with TKIP encryption. Key renewal: 7200 sec. Not sure if this can influence anything.
I've checked on linksys page for fw upgrade, they only have pdf manuals.

Have you checked that you set up the router with b/g/n protocols? not only N..
Try to change the password encrypting method, to WPA or WPA2 or WEP, try also to change the default password.
Have you tried to disable the firewall (DMZ)?

I have exactly the same issue on my stock Desire.....
I have recently upgraded my router from a Belkin G+ to a Belkin N+ and using the b/g/n setting the desire WILL see the connection but will NOT connect to it, NO MATTER WHAT settings you try. Changing it to b/g and it will connect without any issues.
It is my understanding that the Desire/Nexus et al doesnt have the access to the N ability enabled (it has the correct chipset but for some reason it is not active).
Maybe when broadcasting the tri-band the chipset only sees the stronger N connection, therefore tries to connect but gets conflicted (due to lack of N firmware) and instead of switching to b/g it just loops to the stronger signal. IF that makes any sense

Well, the funny part is that I don't even know how to disable the N range to my Linksys 300N.
Anyway, it is weird that the Samsung Galaxy S had no issues with this, while Nexus S (still Samsung made, brother-in-law to SGS) has this issue. For HTC, all have had this problem, including Desire, Desire HD, Wildfire.
Still no explanation or resolution to this matter.

I may have fixed this issue (well I have for me anyway, so yay).
After posting this I decided to apply some weird logic to it. So I reset the router back to b/g, to do this you need to log into the router IP settings, for Belkin it is 192.168.2.1. On linksys routers I think it is 192.168.1.1 but check to be sure.
Once you are logged in there you can change the broadcast settings from N, b/g/n or b/g etc.
Okay, so here is what I did. I reset the router to broadcast b/g only, my Desire would connect. So I decided to try resetting the router to broadcast b/g/n (because I use N on other devices) and then switched the wifi on the desire off and back on again. Low and behold it connects.......Tried it loads of times now and connects everytime!
Might be worth a try?

You guys should just check the logs on the router and see what they say. Should give you a much better idea of what the issue is. You can then Google the error line.

Mine is fixed now, been connecting to various N routers with NO probs since I did the workaround.
My guess would be a protocol conflict (wireless handshake if you prefer) when N routers are broadcasting (based on the fact that the Desire/Nexus etc dont have N protocol enabled in the chipset firmware).
To get around the conflict connect to an N router using the b/g only setting in the routers IP settings and then check you can connect okay and switch the b/g/n back on in the router. I've done this twice today (different N routers, a Linksys and a D-Link) and it works on both where it wouldnt before, so it wasnt just my router.

hum... i am having the exact same problem as described only my router is already using
802.11g&802.11b
i have no idea why it keeps trying to obtain ip address
then it scans agains because it can't connect and tries to obtain the ip again
after trying for a minute or 2, the home ssid becomes:
"disabled, secured with..."
(device = motorola atrix)

I have tried everything and still not working... do routers block Mac addresses if it doesn't connect right away?

[Q] Wifi on my Sensation works fine everywhere except im home!

While everywhere I go I can get a wifi internet connection, when I try at home I connect to wifi but I cannot get any data connection! My router is fine because all my friends use it to connect on the net with their phones.
Any ideas anybody?

A possibility
There are some cases where the router is not compatible wit Android devices and allows them to connect properly onto the wifi network, but not getting the proper IP, subnet and so on. Have you tried to manually enter these details into the phone and try out if there will be any Internet access afterwards or not.
In some other cases, maybe the DHCP pool is empty so it can not provide you with an IP, where manually entering the IP details should again help. But I think this is very rare case. About the first case though, I met some issues with the routers and the Android devices.
Hope this will solve the prob..
Have a lovely day!

Did you try rebooting your router? This happend to me sometimes too, my laptop can connect just fine but not my phone & a router reset always fixes it.

I have tried to manually enter the IP address, subnet and so on into the phone but still I cannot get an internet connection! I have also rebooted my linksys rooter but still nothing!

Log into your router and change the output channel. Sometimes if the router is putting out on a high channel say 13 for example this can cause some devices to not be able to communicate with it. So try changing it to a low number say 3. This should solve the problem.

This is more than likely because your router is set up to automatically switch to the channel that is the least congested, again if this is a high channel this can cause problems for some devices. What you are doing when you turn it off and on again is resetting the channel. I recommend you also manually select the channel by logging into you router and changing the settings.

I changed manually the router number several times but still no connection!

This issue is due to WIFI encryption. Try WEP or WPA encryption. I was facing the same issue. When i changed the encryption to WPA I am able to access the net.

Yes, it might be encryption, might be the channel selection as well as previously stated.
The thing with the channels is not only if they are on higher or lower, but they are just a little hops on the frequency side so for example if some other device is working on the same or close to yours channel, it might interfere and give you disconnections from the wifi, slower speed, no connection at all etc. etc.. So in some case the channel selection (changing the wifi channel) may do the trick. Unfortunately in your case as I can understand this is not true.
About the encryption, there is also one more thing as a security and that is not allowing the devices automatically, but with it's MAC addresses.
I would recommend just for testing purposes to try and disable all the security and check out the connection that way.
What sort of IP details did you entered on the phone? I mean - I was thinking of entering an IP different from the pool, subnet usually 255.255.255.0 (depends) and the Default Gateway to be the router's IP. Then for the DNS if you can try with the OpenDNS and one from Google.
And if you would like to share some info if there are any other devices connecting with the wifi at the premises and how they are working.
Hopefully you will resolve the issue, soon!
Have a lovely day!

having same issues ever since I flashed latest insertcoin ROM
I tried the 2.3.5 ROM and was having issues connecting to wifi, so I went to the 2.3.4 SSE, but wifi issues did not clear up. It hangs on obtaining IP.
This happens for all settings, static and dynamic, router reset did not help, modifying channels did nothing, neither did changing encryption settings. The wifi connection works for every other device in our home, including a stock Sensation.
Thanks in advance for any help. Since I'm a noob on forums I can't post to the dev section about this.

Hi, since the stock sensation is working properly, why don't you flash the relevant stock rom and see if that works, seems like all else failed

[Q] Wifi Problems

Hey guys/gals, I have a problem with setting up the wifi on the tab 7.0 plus.
It sees my SSID - I enter in the password, it says obtaining IP - but is stays there never actually giving me an IP from my router. I get signal strength, etc. but I cant access the net.
So i decided to try to set a static IP, but that did not work either (but not sure I did this entirely correctly, so ...)
Any solutions? Whats the problem? it can be that hard....

The likely problem is that DHCP isn't running on your network (or isn't working.) DHCP is something that usually will run on your router and assigns IP numbers to devices that connect to it. It's also possible that DHCP is working fine, but you have MAC Address filtering enabled on your router (which basically limits which devices can attach to your network.)
Finally, it might simply be a router incompatibility (though I haven't seen that very often.)
As to how to resolve those things... I can't answer that... I don't have the same router you do (unless you just so happen to have a linksys E4200), so can't walk you through reconfiguring it.
Good luck
Gary

Had the same problem at the beginning when I unboxed my Tab for several times. After few resettings my router an Tab it finally started to work and since that moment couple of days without any issue. So don't know where was the problem..:-(

I also had DHCP issues upon unboxing the tablet. When it first powered up and tried to connect to my D-Link router, my Wi-Fi would go offline. All of my other connected devices would also go offline. After pondering this bizarre behavior for a few moments I decided to turn off the tablets wifi. The router and other devices magically came back online and connected.
After repeating this several times just to make sure I wasn't seeing things I assigned a static IP to the tablet. Everything worked fine after that.
What I think was happening there was that the tablet was trying to grab the router's IP address and that was knocking everything offline. This is just a guess though. Maybe someone with more network saavy than me has some thoughts?

thanks i will try these tonite and reply back.
My Tab is rooted, but I dont believe that matters, correct?

Yes it shouldn't matters...

So i played around, couldnt get DCHP to work for an IP. So i went back to creating a static IP - i missed 1 digit on DNS1 the first time which is why it didnt work last night. Once the static ip was up - boom.....magic. I called samsung support, they indicated that this is a know issue with some home routers (mine is a 2wire) and that a static IP is the solution.
thanks for all the tips above, much appreciated.

[Q] Wifi doesn't work at home

Hi,
I have a problem with the wifi on my Samsung Galaxy S2 after I changed some settings on my home router. The wifi works anywhere else, just not at home.
What I changed was the router ip and wireless channel. Since then I have cleared all the wireless and browser settings in the phone and reverted back to the old settings on the router. Still doesn't work.
I've also tried having static IP. It doesn't work as well. It's only the internet. It connects to the router fine and I haven't had any problems with other gadgets and computers connecting.

Your tried turning on airplane mode for a few then reboot?
Your router doesn't have a sync button does it?
*signed

One thing you can do is delete the connection to your router on your phone, and connect again with new password from router. Do you have any other device beside your phone connecting to this router? If no, you need to test it. If yes and not connecting check the connection security, like wpa or wpa2. If all fail, reset router. This mean you will need to reconfigure your router. Check manual for more on your router.

Yes. View available wireless connections. Click your router. Then click "forget".
Then view again, click your router, and type the passphrase.

I've already reset anything wifi related on my phone. It hasn't worked.

Do you have something else that you can connect to wifi to see if the problem is your router?

Not in my home no. But like I said in the OP, the wifi on my phone works fine in other houses and hotspots. It's most definitely some kind of communication problem between my router and phone only but I'm not familiar enough with routers to know the problem and I haven't stumbled on anyone else on google having the same problem.
Two laptops, one Win7 and one OsX, are connected. Unfortunately I'm new in the area I live in and my girlfriend doesn't have a smartphone so I haven't been able to test if it's just my phone or just android or iPhones in general.
I can't think of a logical reason why it's like this

Maybe router is configured with wifi 802.11n and the galaxy only runs on b/g ?

If you're using WPA/WPA2 security, check that the
router is set to use AES encryption.
If you think you did your best. Its better to buy a new router then. )

maybe you could try unplugging your router?
