[Q] Tab S 10.5 not reconnecting to hidden WiFi access points - Galaxy Tab S Q&A, Help & Troubleshooting

I was setting up a new Tab S 10.5 on a relatives network. The access point (router) is not set to broadcast. Of course the first time I wanted to connect I made the router visible and then the Tabs S connect per usual. After that I change the router back to invisible (no broadcasting). I fully expected the tablet to automatically reconnect with the router but that did not happen. I toggled the tablet's WiFi but I could only reconnect after I made the router visible again.
My relatives laptop has no problem connected to WiFi even when the router is not broadcasting. Its likely that some other tablet setting has been turned off. This is a relatives tablet and network so I can't experiment. On the tablet I'd turn off automatic WiFi scanning to save battery. Could that be the culprit?
Basically I'm asking if this is a Tab S issue that other owners have experienced?

Try using either 2.4 or 5 GHz channels with standard b, g, n etc.
Also try the same connected to a different brand of router.

[Q] wireless n connection .

Hi all
Wondering of anyone else is experiencing this. My gn won't connect using wireless n regardless of distance to my router. Connection speed is always below 54mbps. My laptop connects no problem.
Currently using codename Droid and router is billion 7800n. Tried forcing both router and phone to use wireless n.
Try resetting router. Before doing that make sure you have your router set to allow x amount of connections. I had my router set to allow max 3 connections and when I tried connecting my nexus one the other day I had to bump it up to 4 since my N1 was a 4th user.
Sent from my Nexus in Texas.
tried all of the above. quite frustrating when the GN is supposed to be able to do wireless N.
found this http://code.google.com/p/android/issues/detail?id=22474, gonna see if that helps/goes anywhere
What frequency are you using? What is your beacon interval set to on your wireless access point
hi,
Same issue :
connecting at 68 Mbps max.
2,4 + 5mhz both ...

This is an important point. I would also add, if you are using both spectrums, are you using the same SSID on them?
Typically if you use both spectrums, you would configure them with differing SSIDs. When given the option, I have seen the GN prefer 2.4GHz spectrum over the 5GHz spectrum.

[Q] wifi help

My note wont connect to my wifi at home. It connects to work and my hotspot just fine. Also every other device including my nexus 7 connect just fine. What could be causing this?
Try a different access point manufacturer. My fried also has a Note 8 and he had the same issue. His router access point was from TimeWarner. He added a Linksys accesspoint and worked just fine.

Do a little more troubleshooting. If it connects to every network except yours, we can confidently say it's your router. Does it even show up on the list of available networks? Be more specific. What kind of router do you have? is it dual band?

I have the 105mbps internet through Comcast so we have their brand gateway (modem/router combined). Basically what happens is the tablet will connect to the network but has no internet access. It shows everything is OK but as soon as you try to load any website it says webpage not available, the play store won't load, etc. But its weird. All devices listed in my signature connect just fine, and so does my smart TV, ps3, and blue ray player, there is literally nothing else that won't connect.
And yes I've tried the basics of booting everything off the network, changing channels on the modem, changing encryption settings and factory resetting the gateway.

The issue of my Galaxy Note 8.0 (3G vesion) is WiFI unstable connectivity.
All of my devices (3 other tablets and 3 other notebooks ) work well with the access point.
but Note 8.0 is just unstable, taking a lot of time to load data for youtube media app, and webpage .
I had tried a different access point manufacturer, but the issue remains.
I had upload some YouTube video ( but voice is using Chinese/Mandarin lagauage)

I've had the same issue with the same Comcast router. Every other device works except for the Note 8.
Just bought a note 8.. also have comcast modem router with phone combo.. same issue. Connects fine but internet wont work. Huge bummer which I think is going to make me return it and get an ipad mini instead.

Why would you gimp your self in to a less capable tablet because your ISP's god-awful router doesn't meet the standard? Seriously, you would be doing your self a HUGE favor by going and getting a real router and dropping that crappy gateway/access point off your monthly bill (you are likely renting that POS from comcast.)

Exactly, especially with APs being so cheap these days.

I'm having the same problem with my brand new Netgear router. I have a feeling this problem is similar to the issue the Note 2 wifi has. Unfortunately, on the Note 2 there's a code you can enter on the phone interface that allows you to turn of it's wifi power saver mode (that's what causes the problem on the Note 2). With no phone interface, I'm not sure how to get to that setting on the Note 8. Changing it on my Note 2 made a TON of difference though. On the Note 2 the code is *#0011# in the dialer. Anyone got any ideas?
Same problem here with one of my routers. It works for a second or two then disconnects. The only way to get the Note working was to disable wifi G and N modes on the router, and only use B mode.

Tab Pro 8.4 connects to wifi on 2.4 and not 5, any way to get it to use 5?

I have a Netgear Knighthawk router and the main network is one name that utilizes both 2.4 and 5 and as long as the connecting device supports it, it should connect on that band.
My Nexus 5 and wife's S4 which are right next to my Tab are connected on the 5 band.
Any ideas on how I can force the Tab Pro to connect mm on 5?
Thanks
I can't remember in detail but I had mine connected to 5ghz but switched to 2.4 a while back.
If your tab can't see the network or is having a prob connecting to it, then enable broadcast if its disabled

Try changing the 5GHz channel your router is using.

My network only has one name but it is both 2.4 & 5 so when I connect its only one option.

I will try this, I have been messing with the channels for the 2.4 but forgot to do that with 5.

If your using both 2.4 and 5 at same time, that might be your problem. Change the name of one of them. Xxxx5. Or something

I would really like to keep it as one network, I have had it like this since I set it up and have had zero issues. All AC devices connect to 5 and N to 2.4, this is the first time it may be an issue but my wife's S4 connects to 5 with no issues currently.

It seems your tab pro might be defective and not able to connect to 802.11ac, it can only connect to 802.11n which on your routher is running on 2.4GHz.
I had an issue with wifi one, for some reason it wasn't connecting right after some investigations. I enabled ssid broadcast and it worked again. I'm figuri g it was the rom being glitchy.
So try enabling broadcast if its disabled and see it that works

Tested out my Tab by connecting to my guest 5ghz network and tab connected fine. My router let's you combine the main network 2.4 and 5 into one name but guest network must be two separate names for the 2.4 and 5.

Are you sure that your guest network 5Ghz is running with 802.11ac and not A/N mode?
There are some incompatibility with tab pro and some routers.
I'm using tp-link wdr4600, 2.4ghz and 5ghz works fine. A friend, using different router, has the same problem as you, and sometimes the connection drops.

Have you loaded a ROM other than USA? I'll look for the link, or search for posts by me, but i had a similar problem with an S4, and it turned out to be some countries outside US use different frequencies that keep it from connecting at 5ghz. Just needed to change a couple of settings in some files and all was good, or load a USA ROM.
Sent from my SM-T320 using Tapatalk
I haven't loaded any ROMS, running stock version that came with Tab from my US Best Buy purchase and I also did the OTA update.
I haven't checked if my Tab is running on N or AC when connected to my guest 5ghz network, I will have to check that soon. I will also need to find someone who has an AC network and a different router so I can test it out there, but I have a feeling this may be a little difficult for me to do.
Edit: So I checked my router and the 5GHz guest network is automatically set for a/n/ac and there is no option to change it. When viewing my Tab on the connected devices screen I cannot tell if it's connected as n or ac, how can I find this out? Any way to find this out via the Tab?

you can get a app called "network signal info" and install on your tab and other phones. in the app it can tell you what frequency you are connected at.

Tried that app out but all I could see on the statistics was that I was connected to the 5.something Ghz band, this was while I was on my guest 5Ghz specific wifi. I did not see anything about being "N" or "AC". Maybe I am not fully understanding this, but I thought AC was always in the 5Ghz band, is that not correct?

Unable to detect wifi network...!!!

I am using D-Link 2750U ADSL router, the issue I am facing is quite weird. My Phone, Laptop, Nexus 7 Tab can see Wi-Fi Network in range but Samsung Galaxy Tab 3 (10.1) cannot see Wi-Fi network. I tried connecting it manually by providing SSID, it says Network not in range. Interestingly, Samsung tab connects to Wi-Fi network in my office without any issues. So I am clueless as to where the problem is – is it with Router or Tab? Can someone help please

crash your router, try again
access your router, check your settings,history
try unsecuring your wifi, seemif it picks up, then resecure
tab does 80211 abgn, check you're setmfor wpa2-passkey
in your tab if always scan is enabled, toggle it
check system/etc/wifi/nvram* - if present
it's most likely the router and the tab.
Issue resolved (hopefully) by setting channel to fixed number rather than using auto option in router wifi settings.
Interesting aspect is my phone, which is also samsung (s4) and laptop had no issues.
@heeemz
channel!, Uhhh, weird,
My best guess is that you have a router with Full open channels like for Europe or Japan and that the TAB3 is an American version. So as American Wifi is not allowed to transmit on EU/Japan extended frequencies?

Nexus 5X does not detect home WiFi

Hi
I recently bought my new Nexus 5X, but apparently it does not detect my home WiFi. I tried connecting to my WiFi using Connectify or a hotspot from other mobile; which it detects, but says 'Connected, no internet'. I am able to connect other devices to my home WiFi. I tried doing a factory reset even though its a new phone, put it on airplane mode and back and tried restarting it, but nothing worked. Funny it's able to detect other WiFi's in the building but not mine! Please help!
Try to set your router up to chose lower channels on 5ghz

I disconnected one of my devices connected to Home Wifi and nexus automatically detected it. Sorted!
Thanks @ dondavis007. My router frequency band was 2.4GHz and it had auto channel config(channel number was 13 when I checked). When I fixed it to be 1, my nexus detected the router. Don't know the side effects though!

You must not have the international version as to why It can't pick up CH13.
Only downside to this is if everyone else nearby you is using CH1 you will experience slow wifi due to the channel being crowded, download a wifi analyzing app to your phone or computer and you will be able to see the best CH to use.
