Wifi Turns Off

My wifi turns off almost instantly after turning on. Sometimes it will connect to my network and other times it's a no go.
This is a wifi only version and I'm still in the return window so thinking about swapping it out or just taking it back
Android Version 3.2
Kernel 2.6.36-P6210UELA3-CL616928
Build HDJ85B.UELA3
I've been googling for a couple of hours
Stock reset device and wifi sleep policy is set to never. I have nothing installed
thoughts?

I assume that other devices connect and stay connected just fine?
There are wifi tool apps (https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer) that might give you a little better insight to what is happening

Yes, all other devices work fine with the router.
I have tried both DHCP and static and have assigned a specific IP to the tablet from the router.
If I could get the wifi to stay on i'd see what I could download
Edit: Seems to be something to do with the router. I have two in my house (one upstairs and one down). Both resolve back to my uverse model so the routers are just wireless bridges I guess. If I connect to the downstairs and turn wireless off and on I have no problems. If I connect to the upstairs router things go down the crapper

by chance is the upstairs router wireless-n?

Yes. the upstairs is wireless N
Think if I changed it to G only it would work better?

Solution : only connect to WiFi G ?
I have the same issue on my european GT P6210, connected to a Netgear WNDR3800, which has dual band WiFi (2.4GHz B/G/N and 5GHz A/N).
Yesterday evening, everything worked like a charm on the 2.4GHz band supporting N (up to 130Mbps) but today the connection is really random. I tried to connect to the 5GHz band network but to no avail.
So I restricted the 2.4GHz band network to B/G only (up to 54Mbps) and it is way more stable.
HTH, too bad for the DLNA streaming

in my experience the wireless N on the tab + is downright unstable. using wireless G tends to correct this problem. and since i can think of no reason i need 130mbps throughput to the tab, i see no reason not to continue using the G. disappointing though. the tab 7 experiences the same issues

Did you set the tab to only use G? or did you set the router to only broadcast G? I had to set my router to only broadcast G

I have had this problem with 3 different Galaxy tabs. Keep in mind that this is connecting to a work WIFI using wpa2 enterprise. Boggles me that it connects for like 2 mins then drops, only way to reconnect is to disable/enable the wifi. At home using wpa2 non enterprise I can connect perfectly with no drops.

The WiFi on the TF700 isn't horrible but it isn't excellent either. Has anyone found any tweaks or fixes to stabalize WiFi?

Eh? It's excellent.. I get the full amount of bars in a spot where every other device only gets 2 at most. It's never dropped for me. I download entire films over it, at the same speed as my pc and laptop...
Set your IP to static as opposed to DHCP. (long press the network --> modify --> advanced settings) This stabilizes the connection.
Set your router to channels that don't match the ones everyone else in the street uses. Use a tool like inSSIDer (http://www.metageek.net/products/inssider/) to detect all the channels.

Wifi bugs are almost always router problems.
Been my experience that wireless routers are one of the most unreliable pieces of hardware in the realm of networking.

In this case, every other wireless device in my house has no problem getting 4 to 5 bars. I've never really had a problem with Netgear routers.

All wifi routers have short lives because of the high freq oscillators inside (more info than needed I know.)
Had the exact same a few times.
All including the Infinity were fine when accepting a Windows 7 update to my notebook then it's wifi connection freaked.
Reset the router and in one case had to assign a different pass-phrase and all returned to abynormal.

[Q] Wifi 5Ghz problem

The Wifi Range on the 5Ghz is really low. WTF! The signal does not hold just out of the room from where the wifi router is kept. I tested it with wifi analyzer and the signal just drops. To double check I used my Samsung Tablet with 5Ghz band and Laptop with 5Ghz card at the same distance. They work just fine and get full range and speed. 2.4Ghz works okay. But there is lot of congestion in my apartment. So I use 5Ghz. The router is Asus N66U Dual band.
1) I have latest router firmware.
2) WPA2- Personal
3) 5Ghz is running on 20/40Mhz bandwidth in the 157-161 channel.
4) Running stock rooted CM11S.

You are comparing your phone with 2 devices that have at least twice the length of wifi antennas inside their chassis. What would you expect, seriously?

I have the same issue. Funny thing is the lower band 5ghz channels work better but still not like the SGS4 did. I notice the signal drops quick and the disconnects... It's messed up.

echo this... very non consistent 5ghz range as compared to both a nexus 5, galaxy s4 where both of those phones in my house have consistent 5g wireless connectivity.
i had to drop down to 2.4ghz to maintain connection on the OPO

I have zero problems with my two devices connecting to my 5gHz network at home. Always connects, always consistent.

5GHz WiFi Issues

Hello! I'm wondering how many others out there may be having issues with the 5GHz WiFi band on their Galaxy S6? My wife and I are both running a Telus 64GB model and haven't been able to connect to our 802.11ac band since we got the phones last week. I've tried every available channel on 5GHz mode and even turning down the number of channels bonded and enabling 802.11n/a only, but the issue still persists.
If I turn off the smart switch feature, I can at least stay connected and it says I've got a strong signal (anywhere from 580 - 780 mbps) however nothing loads online. I'll also notice that if I am connected to my Chromecast, the signal almost always dies as well so i doubt it's internet-related (although I have tried switching up the DNS entries on my router)
The router is an Actiontec R3000 with WPA2 security, but I noticed I was having the same issue last week on my friend's RT-AC68U when connected to the 5GHz radio. I've never had any issues with my iPad/Apple TV/laptops when connecting to the 5GHz channel on this router.
Any kind of feedback either way (same issues, resolutions, etc) on the concern would be greatly appreciated!

Question Terrible Wi-Fi

Hello everyone,
Is anyone of you experience terrible Wi-Fi performance as well?
In our house we have one main router on the ground floor, one more in the 1st floor (no mesh) and an access point in the attic for smart home devices.
When I'm in the garden I can only see the access point and the ground floor router. When I'm connected to the ground floor router the signal is very bad and keeps on disconnecting even though the distance is maybe 15 meters with only one wall in between. I cannot even see the network from the first floor router.
With my OnePlus 9 Pro I was able to see and connect to it, even though the router is on the other side of the house.
Another thing to mention is, that with the OnePlus I could see 10+ networks from surrounding neighbour's and with the Samsung it's only 2.
Im quite happy with the device, but this is really bothering me. I'm not using some crazy case or sth, just the Samsung clear one.
Thanks for reading, any thoughts?

You didn't say if you was on 2G or 5G? Have tested both? What Routers are they? Hard to help without more details about your setup. I have a Netgear AC1750 Router and 2G is crap at around 50mbps on Speed Test and 5G is much better at 250mbps. But it's a single story house with just the sole Router at one end.

I have separate networks for 2.4Ghz and 5Ghz. 2.4 is better for range and my internet is only 50mbit so speed doesn't really matter to me. Main router is a fritzbox and the second router is from some cheap brand. The setup shouldn't really matter though because it is still working fine with my OnePlus.

That's still kinda vague. What router models are they? Also, if you're running multiple routers, you're going to have problems. In a non-mesh environment, the second router should be configured as either an access point, or as an extender.
You could also be having an interference problem. Either between your routers and AP or from external interference from any neighbors' networks.
In any case, you'd be better served by swapping out your current equipment and switch to a mesh system. I use Google's Nest Wifi with one router and three mesh access points. However, there are several other mesh systems that work well.

Thank you for your comment.
The main router is a AVM FRITZ!Box 7590 AX (Amazon) and the secondary is a cheap Tenda AC6 AC1200 (Amazon). Having multiple routers in a a non-mesh environment shouldn't really be a problem. The Tenda is connected via LAN interface, providing it's own network with its own SSID. It's only for a few devices very close by.
I know there can occur problems due to interferences, but I didn't think it was a problem because the Samsung is the only device having issues. I can try messing with the bands, but honestly I don't think it's going to change anything.

Your setup overly complicated. You are essentially running three SSIDs (One for the FRITZiBox, one for the Tenda, and one for the attic AP). Either reconfigure the Tenda as an access point, or pull it out completely. The problem seems to be the handoff between your primary and secondary router. Your primary router should be able to handle the 1st and 2nd floors easily.
Another question. How many smart home (IoT) devices are connected? The Tenda is capable of only 20 devices. Since the Tenda is upstairs, it's going to have better range than the downstairs router (there is a reason why people tend to place antennas higher up). The AP in the attic is not a router and if it is connected to the Tenda via LAN, the Tenda may be running short on capacity. Since it is higher up, your S22U is probably trying to connect to that device.
The way I see it, you have three options:
1. Install a mesh setup. You have one router, with two mesh points (one on the 2nd floor, one in the attic) running one SSID on both 5GHz and 2GHz bands.
2. Remove the Tenda and move your AP to the 2nd floor. The AP can easily handle the smart home devices, and provide WiFi to the second floor and attic. It will also reduce you down to two SSIDs.
3. Remove the Tenda, move the FRITZiBox to the second floor and connect it to your internet modem (or whatever device you get internet through) via LAN (you said the LAN is already run between 1st and 2nd floors). Connect the attic AP to the FRIZTiBox (via LAN). That should give you enough WiFi coverage and reducing to two SSIDs.

1 billion issues can cause wifi problem....
1) airport\military base near you
2) powerfull microwave
3) neighbor on the same channel
4) device power management
5) bad case (bad plastic - put in microwave...if it heats its BAD)
6) bad antenna inside of device (return it to factor)
8) in-wall powerline 240v
etc...

Running an Asus RT-AC68U router. I get good 5Ghz signal in every room, the basement, the garage and in the car behind the garage.
Not sure what the issue is but it could be your device.

I highly recommend upgrading to a Wifi6 environment if you have a S22 (but not necessarily Wifi6e). The S22's support 160MHz channels which allows for up to a 2.4Gig multi-stream connection with your phone. My phone will connect anywhere from 1.2-2.4gig in/outside my house depending upon where I'm at in relation to my router. My internet is only 500/500, however, I noticed wifi was much snappier with my S22u over my older Wifi6 phone which used 80MHz channels.
