Default SGS2 cannot connect to wifi networks with hidden SSID

Hello all,

Just wondering whether anyone else has noticed or experienced this.

I have a samsung galaxy S2 and if I try and connect to a wifi network which has a hidden SSID, putting in all the details manually on the phone of the wifi network, the phone will not connect to the wifi network.

If I make my home network broadcast SSID, it will connect to the wifi network. It says connected and it remembers details etc.

If I then turn wifi off on my GS2 .... turn my wifi network back to not broadcasting SSID ... and then turn wifi back on on my GS2 ... the phone doesnt find the network again.

Surely the phone should:
- Connect to wifi networks with hidden SSID's in the first place if all the details are typed in correctly via manual setup
- Remember the details of any wifi network it conncted to and reconnect even if the wifi network is not broadcasting SSID

Wifi network is running b/g/n with WPA/WPA2 PSK set.

Afaik this is a limitation of Android itself. None of my three handsets have ever connected to networks with hidden SSIDs.

I work away during the week and WiFi is available at my remote residents.
The SSID is not broadcast and still I have no problems whatsoever connecting.

So maybe you are just unlucky but I can tell you for certain that it is possible to connect to a router wirelessly which doesn't broadcast its SSID.

What type of router are you using ... also whats your wireless setup:
- Router brand/type --> eg Cisco xxxxDPQ3925 DOCSIS 3.0
- Network mode --> b/g/n ... mixed etc
- Wireless security mode --> WEP, WPA / WPA2 Personal etc
- Encryption --> AES / TKIP + AES

just wondering whether a particular setup works and others dont.

My setup is:
Cisco DPQ3925 DOCSIS 3.0
b/g/n mixed
WPA / WPA Personal
TKIP + AES

Hi,

Just as support, before i started messing with different roms and firmwares, i could still connect to hidden SSD's. in order to do this however, i would have to expose it the first time round, and once the phone had successfully connected turn of the broadcast feature in my router.
From theat point, anytime it was in range, it would connect to the hidden SSID

Had same issue for a short period. Wifi Manager works fine, another good app for that is WiFi Advanced Config Editor. They both allow you to connect / configure settings for hidden WiFi networks.

Default same but different

Hi.

Im having similar problem with my sgs2.

But as ive just found out the solution does not lay in AES encryption (at least for me). Its just absolutely ridiculous how it works and something is bugged but i cant tell what.

My network set up atm:

modem : Netgear DG834GT in Modem Mode.
router: Netgear WRN2000
wired workstations: 2 PC+ server + Xbox360
Wireless Devices: IPad, Wii console, iPhone 3Gs, Galaxy Nexus and my sgs2

ive got static IP pool network cause of server providing services to WAN. I just find it easier.
The reason why i use GT834GT in modem mode is ive had identical problem with it as im having now with WRN2000 thinking that was routers fault and bought other one.

My Problem is that sgs2 detects protected network, asks for password and tries to obtain IP from router. after few seconds goes to disabled, remembered and such. it only happens on my home network.
my handset has set static IP number in advanced option in Wireless settings.
Ive tried every combination of options possible: set network to unprotected, set dinamicaly assigned IP on phone while DHCP off (why do i need it?), on router and every time same story but what works for me is this:
Start DHCP server on router.

Then it doesn't matter if ive got static or dynamic IP on phone. It connects every time!
just cause of that router can now produce conflict cause ive aleady ended up having two devices with identical IP. What drives me mad is why the heck sgs2 connects only by using DHCP when my girlfriends Nexus works flawlessly no matter what.

If thats sgs2 software bug im getting icecream sandwitch when it becomes available.

Default I had same problem

Hi all,

I had similar problem, but resolved it by deleting all other saved wifi networks, after that my phone connects to hidden ssid without problems.

hope that this will help you.

Default Samsung S2 hidden SSID

You can successfully connect to a wifi network with hidden SSID/SSID broadcast disabled.

  1. Select/tap & hold old record of wifi network
  2. Select Forget
  3. Create the same network with all access details manually.
  4. Mobile should now connect to hidden network successfully.

I was having problems with hidden SSID and also found this solution to work.

I even set up a second BTHomeHub2 slaved to my main Router (also BTHH2) because I thought my low signal was the problem but I still had the same issue; even when holding my phone within 4 feet of the slave, it just wouldn't find it.

Fiddled and fiddled until I found the above solution to work. Once it works the first time you should be able to connect as soon as you turn your phone's Wi-Fi on.
