Wi-Fi network available, but no SSID's visible? - Networking

Hi you all, I'm new here, so please be patient with me.
I have a weird problem with my (just bought) Landrover Discovery (Spreadtrum SC8810 1.0GHz Cortex A5) phone.
I con't figure out wether its a hardware or software issue, so I'm asking some advice after searching the various posts.
The phone notifies me that there are Wi-Fi networks available, but when I go into the Wi-Fi settings, it doesn't show any SSID's, so its impossible to connect to a network. See attachment.
Can anyone help me out?
Best regards,
Fedor

Hello
It could be normal, if the admin of the wifi network switched off his Wifi network's SSID broadcast. In this case You need to know the correct SSID name to set up the wifi connection. Other case You can't connect to this network.
Of course if Your phone never see any wifi network may be it is a software or hardware bug, but if it happened only one place, where this hidden SSID is reachable, You need to know the name of the SSID correctly.

Push Menu, then scan.

Thanks for the replies. Please only reply after understanding my question and looking at the attachment.

I've never heard of a problem like this before...but do you ever see any SSIDs? Like at home, Starbucks, ect.

This is either a hidden SSID for security purposes then you should ask for the proper SSID name before connecting else you wont be able to see it even if you scan.....

Like I stated earlier, please only offer sugestions AFTER understanding my question and LOOKING at the attachment. As you can see in the attachment, I have 2 phones next to each other. The Samsung shows plenty of SSID's and the Chinese phone shows none. So wether or not there are hidden networks, is not the issue.
The Chinese phone notifies me that there are available networks (which it should, as there are!), but the SSID's don't show up. Very strange. In other words: it detects the available networks, but doesn't show which ones. So I can't select one to connect to.
My guess is that it has to be a software issue and not a problem with the hardware.
Could there be a code that I can type in, so I can deeper into the WIFI settings?

What android version is each phone running assuming its a software issue?

wifi channel problem

In my house I have set up 2 wiress routers. One of them is the main router assigning dhcp and is on channel 1. The other is acting as an access point and is broadcasting on channel 6. Both are using the same ssid, and all of the security settings are the same. Anyway the network works fine. All devices flip to the strongest channel while roaming throughout the house, except this one. This one is locked on the weaker router (further away). I have tried forgetting the network and re-adding it. Any ideas? Is there a way to force the wifi on this to a specific channel?
I use a free app called Wifi Analyzer. You might install the app and look through the various screens to see what is going on in your network (they are easy to use). This will allow you to confirm the actual signal strength at various points in your home. It is possible that one of your neighbors might be using a channel that is interfering with yours. The app will help you understand what is happening.
thanks for the speedy reply! I actually have that app also and love it. that is basically how I know that it's using the weaker channel. I don't have nieghbors so that is not a problem. the biggest thing going to point me in the direction of something wrong on the Samsung is that I have a couple of thunderbolts, an incredible, and 2 wifi laptops that under testing all switch channels correctly.
So I just took another look at wifi analyzer. One of the sceens asked me to instal wifi connector. After I installed that I was able to connect to the specific channel. So thanks again !

Looking for a way to block specific WiFi signals.

I live very close to a hotel which has multiple SSID's that keep interfering with my ability to stay connected to my router.
I've tried hard coding a static ip on the phone, adding the mac address to router, even went as far as creating a separate unhidden network just for the phone. So far, nothing has worked.
So i was thinking that maybe there's a way to have the phone ignore certain signals, lock on to a preferred one or use WiFi but turn off the scanning feature. The only problem is that I haven't been able to find any settings or Apps that will allow me to do it.
So, if anyone has any ideas or suggestions as how, or if, I can make this work, I would greatly appreciate it.
I'm using a Droid 2 Rooted with 2.3.3 and have a Netgear N750 router.
BTW - none of the computers in the house are having this issue.

So, are you saying the phone constantly tries to leave your home wifi in favor of attempting to connect to the hotel's?
Yes, unless I'm within about 5 feet of my router, the hotel's signal makes the phone keep dropping and reconnecting over and over again.
Sent from my DROID2 using XDA App
Are the hotel's hotspots not WEP secured? That is so odd. If they're unsecured hotspots go over to the hotel and tell them to get their sh*t in order. Otherwise I'm out of ideas, sorry.
No, they are secure. WPA2 as is mine. I don't connect to them. My phone just detects them, drops my connection and tries to connect to them. So that leaves me with no connection and having to use 3G.
But there may be an easier solution to this. After spending a few hours on the Netgear site, it turns out that there is a bug in their firmware that causes signal strength fluctuations. They said a new release should be available in a few weeks.
In the meantime I've changed the channel on the router to auto select which seems to be helping.
I do appreciate you taking the time to assist.
Thanks!

Glad there's at least some kind of work around, wish I was of more assistance.
Having a similar problem with a samsung galaxy sii - current internet configuration is through AT&T U-Verse with built in Wireless G router in there Gateway. tried adding a Netgear dual band N router to my network and with the netgear's 2 wifi signals on then my phone just constantly goes into scanning mode and keeps trying to connect between the 3 - things work fine with the wifi turned off in the new netgear kind of defeating the purpose of me installing it - was hoping to have the phone use one of the N signals..
Block bt openzone connection pleaseee!
Desperately need an app for this? Is it not going to be possible for a way to block certain wifi signals because I'm actually going to rip next doors BT openzone router out of the wall and get a hammer to it! My HTC desire hd is insistent on connecting to its poor signal over our excellent one and the worst part is that you can't actually access the network unless you pay BT for a user account! Grrrr.... Please help
Try to connect the network you dont want, then go to wifi management in settings. Long press on the network you dont want and hit forget network. Then your phone shouldnt automatically connect to it unless you tell it to.

[Q] Able to connect to many different WiFi Networks except school ones

Hello all.
I can connect my Nexus 10 to my home wifi (password protected), my girlfriend's home wifi (password protected), and the wifi at public places (I've only tried ones without passwords so far). My only problem is when using my University's Wifi. They have one that you use with an account and password, and one that is free (though you need to sign in using an email via a website. Kinda like hotels).
This is surprising to me because I have a Galaxy Nexus running the same OS (4.2.1) and it can connect just fine. When my N10 tries to connect, it says "connecting" for a second or two, and then it just says "Saved" but never "connected" and it never shows a wifi connected symbol at the top right.
I have read multiple posts about wifi problems from 4.2 but couldn't find any specifically buggy wifi problems like this. Have any of you heard of this or a solution to it? Any help would be appreciated!
Have you tried a reboot? Also check to see if your frequency band is set to auto under advanced wifi settings.
Gotta love university security and logins... they can't leave stuff simple
Oh yes. I have rebooted many times and tried using auto, as well as both frequency bands separately.
Hmmm...are you on stock?
Yes I am. Stock on both my Gnex and N10.
I wonder if using a third party wireless manager would help. Search the PlayStore and try one or two. Before you do that, go into your normal WiFi settings and click "forget this network" on the university one.
Hi there,
I work at a University in the midlands and had the same/similar problem. It's to do with certificate revocation in Jellybean (and also the latest ios my colleague tells me). For example on my Nexus 10 I was able to see the network and obtain an ip address but the webpage where you login wouldn't redirect or load. I don't know what Uni you go to but we are advising people to give the IT dept a call and give them your mac address and they can create a fixed profile.
Hope this helps
I'll definitely try the third party app. As for telling the n10 to forget the WiFi, I tried that many times too
Well that's why I mentioned my gnexus because they're the same android versions so if it works on one it should on the N10. I actually work for tech support at my university and my boss couldn't figure it out or suggest a process like you described. Thanks, though!

Oh yeah you did mention your Galaxy Nexus, my bad! let us know how you get on with the third party app. You could try giving your N10 a static or reserved IP if you have access, as a workaround!
Hey guys,
I'm from France and had such trouble with my Motorola Milestone and my HTC HD2 (and friends too with Samsung Galaxy S2 and Sony Ericsson Xperia Active) with my school's network. If it's an Eduroam network, try Eduroam Fixer from PlayStore, it helped all of us except one Samsung Galaxy S2. Give it a try

I wish I could use that app, but it says I can't use it in my country (USA)

Make sure you have the EAP set correctly and check if you need a phase 2 authentication. For example, here at UofM we use PEAP for eap and mchapv2 for the phase 2. If you don't have details like these, your tablet won't connect even if you have the proper login.
You will find them at the top of the page you use to login to a secure network.
Hope this helps!
Yes, that is exactly how the secure WiFi is set up at my University, too! What should I do in this case?
Edit: Nvm, Just noticed this was already tried
I had a similar issue with my One XL. It was a frequency issue. I switched it from 5ghz to auto and all was good.

Okay so I found out that my N10 is able to connect to the exact same WiFi network when in another building. I believe there is just an issue connecting to the specific router used at a computer lab. Will update when/if a resolution arises for that lab.

NexusHD2-JellyBean-CM10 V1.4a - Networking issue

Hi
I just installed the NexusHD2 ROM today, and I experienced a bug/issue with this ROM.
The problem is that my wireless network is hidden (doesn't broadcast SSID and doesn't show up on list of available networks) and therefore no devices will see that it's there, unless they know it's there. I did have the SENSATION XL v3.0 Android 2.3.5 on the device before and that one did not have the problem. Before that I had some PACman JellyBean ROM, which also didn't have that issue.
My HTC One X with stock HTC 4.1.1 ROM also registreres my hidden network without any problems.
Now in order to get connected to my network, I need to tell the OS (doesn't matter if it's Android, WP, iOS, Windows, OS X, Linux) that it's there, and also tell the type of password-encryption and what the password is. This proces is just the same on every single ROM I used, but only difference is that the NexusHD2 JB ROM doesn't recognize the network when it is hidden. If I then go to the setup of my Wireless router and turn off the hidden network, so that anyone, within range of the wireless router, can see it, then it also is recognized by the HD2 and it automatically connects. When I then hide the network again, it stays connected, until I reboot the phone or until it turns of Wi-Fi to lower power-consumption. When it then tries to reconnect, I have the issue again, where it tells my that the network is out of range/not available.
Does anyone else have this issue, or does anyone know how to fix it, without having to change the configuration of my router.
I have the HTC HD2 EU 512MB Version
Just go to settings and add the network manually. The plus sign at the bottom of screen!

I use the same setup - hidden network - without problems. Not sure what the problem is but I would try a lower channel number and/or set a different encryption method on the router to see if one might make a difference.

[Q] Can't Connect to WiFi Network That's Not Broadcasting SSID

I just purchased the Samsung Galaxy S5 and I have a Western Digital My Net N750 Router. I have SSID Broadcast Disabled and the S5 won't connect. If I start broadcasting the SSID it has no problems connecting.
I have over 20 other devices that have no problems connecting with the SSID disabled, so I don't understand why the S5 can't do it. Even my 3 year old Samsung Galaxy Nexus has no problems connecting with SSID disabled.
I called Verizon and they said they haven't heard of this problem before and that the phone is defective and to return it for a replacement but I have a feeling I'll have the same problem with the replacement phone. I've searched Google trying to find people with similar problems but I can't find any other posts. Can you please help me! Thanks so much.

Perhaps so, but if you don't you won't know for sure. You can try to get it working, but if you exchange and it still continues to not work, then Verizon has it on the books that you had a defective device, and they can start working on fixing that silly problem.

I was hoping someone with the same phone can test it to see if they have the same issues. I'm going to do a factory reset right now to see what happens for troubleshooting purposes. That's also what Verizon recommended that I do. Then I'm going to Verizon to exchange it. If someone else with the same phone can test it to see if it works on your phone or not I would greatly appreciate it!! Thanks so much!
I wonder if it's a compatibility issue with my router. Maybe I should go try it on someone elses router and not broadcast their SSID and see what happens. That will help me determine if my phones defective, or if it's a compatibility issue, etc.
I'll still do a factory reset and replace the phone if I still have problems to see what those results are too. It would also be helpful if people with the same phone tested it out to see what their results are. Thanks!

Thanks for the information. To help me trouble shoot it did you connect 2.4Ghz or 5Ghz? What's the make & model of your router? I'm trying to figure out if my phone is defective or it'a a compatibility issue with my router. I'm trying to connect 5Ghz so maybe I'll try 2.4Ghz now. I'll also try connecting with someone else's router. Thanks!
Try adding the network manually

I had this same issue. It would happen if I had the SSID broadcasting, connected my S5, then turned off the broadcast on the router. It wouldn't work if the phone had found the network through a scan. I got mine to work (with my Netgear R6250) by adding wireless network manually on the phone. Hope this helps you, too.
Any resolution on this? I have the same issue. Since I'm rooted and happy, I really don't want to return my phone.

I am aware this reply is over a year later but I am assuming that there may be others this issue is happening to.
I also had the identical problem. When SSID was set to broadcast, the One Plus and Samsung Galaxy S5 would connect without any issues as normal. When the SSID was set not to broadcast, I would have an authentication error and/or show the WiFi connection saved. All this started after the router's f/w and both phones' (Android)OS were updated. This was on both the 2.4GHz and 5GHz frequencies.
Here's the solution - this is done on the phones/mobile units having the connection issues AND having your router's SSID's set not to broadcast.
1) Hold and press the WiFi connection and select "Forget"
You will now more than likely see those available. Make sure you don't use these connections
2) You now have to chose the option to "Add Network" from the menu (One Plus) or "Add Wifi Network" at the bottom of the WiFi settings on the Galaxy S5.
3) Manually type in the SSID you want to connect to, select the type of security and enter the password for your WiFi
4) Repeat steps 2) and 3) if you have a second SSID you want to connect to
5) You should be able to now connect to your Wifi network, if not reboot your phone/mobile device and you should now be able to connect.
Hope this helps you out.
