[Q] Wireless signal issue in case of hidden network. - Wildfire General

Hi All,
I would need your advise / experience on a wireless problem experienced in a last few day.
So when I'm connecting to a hidden network with wpa2/psk encryption, the signal is not solid, but periodically disappear completely ( measured by wifi analyzer from the market, and the lack of connection is affecting the browsing also ).
When the ssid is not hidden the connection is stable, and the signal is solid.
Tried with 3 different routers already, so it should be a setting at the phone, or maybe a kind of driver isssue.
Any hint appreciated.

It would be also fine if someone reproduces the mentioned circumstances, so I would be able to identify if it's a unique behavior or a general one. Thanks.

Wifi sucks :(

Hi all,
I just got my device, and still thinking whether to send it back in 7 days. My main complain is the wifi. I have never seen more than 2 bars (out of 4) signal strength, even when sitting 2 meters from the router. Moreover it always drops the connection. I realized it when I tried to use IE for browsing, since that doesn't tolerate it and I keep getting the connection lost messages. Seems that Opera can live with it, but I see when the connection dropped during the page load. Youtube watcher also cannot manage to download videos when the signal is dropped.
The Tx/Rx rate also changes chaotically from 1Mb/1Mb to 54Mb/36Mb.
Before you ask: the Power Mode of wifi is set to "Best Performance", since this is the only way it is usable.
Anybody else with similar experiences?
Any solution?
I really appreciate any help, I would like to keep it!
I have no problems what-so-ever with the wifi on my D2...
It runs very well, in all applications that can use it.
- and I have full signal when I am within 5 meters of the router.
I haven't changed any settings on the device, and the router is running on WPA2-PSK at a channel not used by any of my neighbours.
Maybe you have many wireless networks in your area?
Hi,
I have more or less your problems (I opened a thead about it the day I unpacked my D2 but wasn't really condiderated). Here's my condition: I have 3 HTC devices...Artemis-->regular functioning (balanced power), TytnII-->Power Performance MUST be set to high performance, Topaz..well I could connect with balanced power but since I upgraded radio I have to keep it set to best performance, otherwise I would get "fake" connections (connection established but no data taffic). I don't really bother to have to set it like that because the connection is dam fast, which compensates the higher power consumpion.But beside this, I must say that my router is not very friendly with my D2,e.g. when I don't get a connection,I restart it and it works (this must have to do with DCHP service). I have much less trouble connecting alsewhere. So ,what to say? Try to change radio...Do you have other wireless devices working regularly in the same area?Do you have an original rom?You could also try to change wifi channel..would be happy to help
Hi,
Thank you for the answer. I have original ROM, just checked the radio, it is: 3.43.25.19. I didn't experience "fake connections" when it is connected, it is so .
I cannot change the wifi channel, the same router is used by others. However it cannot be the cause of my issues since my notebook's network works fine on the same router.
Changing the radio... seems a good idea. It is my very first smart device, I even thought that this version number was for the hardware, not the software . I will find out how to do it, maybe give it a try. Hope it is an officially supported action .
Hi Lamsebamsen,
The TD2 sees 4 wifi networks, my notebook sees 8. Is it many or not? I think the 4 which the TD doesn't see is many .

I'm afraid not, as you would have to HardSPL your device first. There would still a way to get back to your original configuration but I don't know if you are prone to do so, that depends on how much responsability you can take on your device (is it from work or..). Another thing to try is to manually configurate your connection (e.g. assign D2 always the same IP, but watchout for network collisions!router should be set aswell)

[Q] Bad WiFi connection. Any solution?

Hello everyone,
yesterday my new POV Mobii tegra arived. Everything works fine, except WiFi. Mostly i cannot connect to any WiFi network. If I get a connection, its very slow and often disconnects. I found other threads where people facing the same problem, but I didn't found a solution.
With my HTC Desire and other WiFi devices i do not have any range problems.
I tested different ROMs (corvus5, modaco r8, stock, buzz07 kernel) with various builds of the WiFi Driver (AR6k).
Has anyone a suggestion what I could do to get a better WiFi connection? Could this be a hardware defect?
Thank you!
Markus
I have this problem too. I have experimenting with different wireless routers. My operator provide me with a Thomson TG784 that has a weak signal. Now am using a Edimax BR-6504n. It is a bit better. But I am thinking of getting a Netgear WN2000RPT
Repeater. If anyone have a Netgear WN2000RPT please let me know if it is any good.
It would be interesting to know what people are using. So feel free to post the name of your wireless routers here!
If you have WiFi connection issues, it is worth checking that you have Bluetooth turned off. WiFi and Bluetooth seem to share the internal aerial and there are wquite a few posts about the two interfering with each other.
today i made more tests on signal quality. if my mobii says "50%", my router says 0% signal quality. if i'm on the same room as my router is, my mobii says 100% and my router says 13-18% signal quality. what the hell?!
I am having some connection issues aswell. It seems to drop connection but when I switch aeroplane mode off then on it seems to wake up the wireless and connect again. Really annoying, wondering if to return it back to the store.
Is there any fix? running 4.3 and no updates yet.
ps. my router is a Billion 7800n

[Q] N10 WiFi will not connect to some networks

I have read the threads about WiFi connection dropping, but my N10 has a different problem. With certain Access Points (primarily at public hot spots), the N10 will simply not connect. The status alternates between "Obtaining IP Address" and "Saved". Signal strength is excellent, and I can connect to the Wi-Fi network just fine with my Nexus S phone or notebook computer. Only the N10 is unable to connect.
Has anyone else seen this? Is there any application that can help with debugging this sort of problem? It would be nice if there was a log file that had more details of exactly what's going on.

Under settings:wifi tap the extended options and uncheck wifi optimization. This may solve your problem.
Unfortunately you may have vendor incompatibility to blame for your problem, in which case there's nothing much you can do.

Will try optimization off. If that's what is breaking it, I guess it is not really an optimization, then....
Please explain how "vendor incompatibility" might be an issue. Are you saying that the Wi-Fi implementation in the Nexus 10 might not b Wi-Fi compliant? Has it been Wi-Fi certified?
Search the Q&A for wifi threads, there are a couple big ones where this sort of thing is talked about. Usually it comes down to the router on that wifi network simply wont work with the Nexus 10 unless you do some major tweaking to its settings. The problem is that many router vendors simply do not follow proper standardization and this leads to incompatibility with devices that strictly ad-hear to these (supposed) global standards.
I posted in both major threads the settings I found to fix the wifi dropouts and non-connecting problem. Unfortunately not many routers are able to properly set those options and you need custom firmware to do it.

If you know what you are doing any cheap router will work just fine, you just may not be able to leave the room. changing the broadcast channel from auto to 1,6, or 11 will help, using WPA (original) encryption with psk-tkip seems to work best for most ISP/cheap routers. Try turning Bluetooth off that can cause problems with weak signals.

WiFI PROBLEMS

Sometimes I am not linked to my wireless network. And when connecting to is really slow..
The network may be no problem.
Someone who has the same problem;
Thank you very much.

I'm facing the same problem here. And as you say network it's not the problem. It seems a kind of random incompatibility, because it works on other connections, at friends' companies, other people's homes, even in the hotspot on my laptop.... But still having this issue at home, with my wireless connection.
The stranger thing is... it works without any issue for days, and suddenly, the problem starts, by saying: obtaining IP adress....
From my research - for a solution - there are several devices from other brands that have been facing the same problem.
Edit: I am using Nova Launcher and Teslaunread. I just remove Teslaunread - only to test purposes and... quickly the device has connected to my wireless connection. It worked for me and surely i can live without the notification badges
I use Tesla unread and no problems whatsoever...
I have the same issue with slow wifi. I compared the wifi speed of P9 and P9lite in one environment and wifi fi speed og P9 is twice lower than p9. Anyone with the same issue and found resolution?
I solved this issue by heating the wifi chip with a thermalgun
the wifi chip is behind a metal shield, you can just heat on the metal shield
that way the chip resolder itself

S8 Internet connection may not be available issue

Just got the S8 and I have 3 Wi-Fi access points at home to cover the whole house. My S8 has been registered with the passwords for all of the APs but it continually rejects the connections with an exclamation mark after the WiFi icon having connected and then shown a message that the Internet connection may not be available. The Internet connection is available as other devices are connected and using it perfectly. If I switch the Wi-Fi on and off and reboot the S8 the issue corrects itself but I should not have to go through that nonsense every time I come home and want to use my Wi-Fi. I have explored the advanced options on the connection settings and they appear to be quite limited (DHCP Etc). Is there some way to solve this issue? I have no problem with other android devices connecting to the same hotspots. Any ideas that might lead to a solution would be appreciated.

I had this problem when i first got my s8 from vodafone but when i got this latest update it's been good no issues with internet anymore.
I have this problem as well with my S8 from Verizon. Worked flawlessly for a week and them today I get this error. Very frustrating. I know the SMG955U from Verizon is already unlocked but is there any way to put the International ROM on the phone seeing that the Verizon and the International are the same?
I've tried all the resets etc and the WiFi connects but I get the 'Internet connection may not be available' message.
Update 27/04/2017
Thanks for the reply. My S8 developed some interesting issues including the switching on of 'do not disturb' mode intermittently and along with the Wi-Fi issue the mobile data was failing in areas where a full 4G signal was present. Rebooting, resetting etc did not resolve the issue and I returned the phone to CPW for advice. The staff at the Glasgow store wasted no time and exchanged it on the spot after some negotiation with their technical service centre. Full marks to CPW for the prompt service and I can report that all of the previous issues have now been resolved with the replacement handset. I thought it worthwhile to post this information so that others who experience similar issues may be able to get a similar resolution.
Poor WIFI performance
I also have issues with the wifi of the phone, /i will get the terminal replace some time today or next week.
1. WIFI keeps disconnecting, actually it's flapping connct&disconnect for 5-10 min until it finally connects, on this matter I have seen on the acces point that it tried to allocate an ip from an unknown without asking DHCP server for an IP renew it actually tries to alocate itself the last known ip, and clearly disconnects because of lack of internet access, this happens normally as power saving mode is on, disabeling power saving and assigning a static ip on the phone seems to resolve the issue.
2. poor wifi signal... no fix for this thus far
- i have 580Mbps speed connection on my S5 and only 120-240Mbps on my S8, steaming not working and connection in general very bad, time ots and stuf, although I position myself at 10cm away from the wifi router antenas i only get 540Mbps signal, although I have an AC1750 router , s5 gets 840 in the same spot... I think the modem(that is part of the Exynos chipset) does not work wekll with Atheros based AP´s , I have an Archer C7 with 2.4ghz QCA9558 chipset capable of 450 Mbps theoretical speed, but only uses 2 antenas as s8 only has 2 from my knowledge and reaches a max of 140Mbps(should of connected at 300Mbps at 10cm in theory ) with the s8 and QCA9880-BR4A on the 5ghz side of things with a theoretical speed of 1300Mbps should work at 866 with the S8 because of the 2 antenas of the S8.
phone changed 90% of problems fixed
Hello, just got my phone replaced, tha new unit has way better wifi signal considering I hace atheros router and the phone has broadcom 43xx chipset... worth considerign changing to a broadcom router...
Hi,
I have found a solution to this problem.
1. GO to wifi settings
2. Forget the wifi network
3. CONNECT AGAIN BUT BEFORE CONNECTING GO TO ADVANCED OPTIONS AND CHOOSE STATIC INSTEAD OF AUtOMATIC. Enter in the ip address etc and connect.( It requires to be entered manually) Problem will be solved.

@Saurav913 doesn't work your tip,but my wifi drop too much especially in stanby (set it on always option) and till I wake up my phone i don't have wifi again with router Vodafone revolution..
Change the DNS...
Hi there..
I had just the same problem with s8 plus and s7 edge(after updating to android 7.0), it kept saying "internet may not be available", I changed the DNS to 8.8.8.8 and tue problem solved. Go to SETTINGS》WIFI》SSID》MANGE NETWORK》change the IP SETTINGS to STATIC》then change the DNS1 to 8.8.8.8 hit save and you are good to go.
Sorry if there are any mistakes. I am new to XDA and not good in english.

I have same problem and it is very annoying. I got 2 S8 plus and both have the problem.
There are 3 WIFI Router that covers my house. I have problems saying internet might not be available every time I connect. This is very annoying. Other Phones in the house like Iphone do not have the problem.
What I noticed is that the IP range of my router is:
192.168.1.1
But my S8 says he is connected but the IP is
192.168.0.100
Anyone have same problem?
Thanks!

I found a quick work around on how to fix this temporarily until Samsung issues a patch.
just turn off 5ghz SSID broadcasting and you should be ok for now.
here is a quick how to video i made on just in case.
https://youtu.be/Nu5FjDPLn-M
I'm having a very similar problem with my home WiFi and my Verizon S8+ I bought from Samsung's website. I've tried switching from DHCP to static and entering all my info. No luck. I've also switched my dns1 to 8.8.8.8 and dns2 to 8.8.4.4, and my WiFi router is set to 2.4ghz only. No success in resolving the issue. Currently my phone will show the "internet may not be available" with the added exclaimation point for a few minutes when first connected, then the exclaimation goes away and I'll have regular full speed internet for around 25-45 seconds before it goes back to a non-internet state. Any suggestions?
Try changing in your router the security setting. If your using WPA2 AES/TKIP, change to just WPA2 TKIP and see if this works for you...
I was having the same exact issue for months. I changed to TKIP only and have been rock solid ever since. No more ! at all... I'm gonna switch to just AES today and see how that works.
Changed to WPA2-AES and within the hour had ! back and no internet. Went back to TKIP and rock solid again. Looks like a possible bug with AES to me. Sticking with wpa2-tkip setting for now.
I'm having this same exact issue.
Anyone who knows what to look for to fix this, what info or files do you need from me? I'm at the end of my tether with this ****
I am having the exact same issue on my galaxy tab s2, even on the replacement. Due to the being such an intermittent problem, it wouldn't do it when Samsung support checked it out...
This happens on both 2.4 ghz and 5 ghz frequency for me. I've tried downloading a wifi fixer, I've reset network settings, and turned off nearby device scanning. I've also tried doing what a forum suggested by changing the ip settings from dhcp to static but it wouldn't connect to wifi at all. Not sure what else to try...
I read that it may be due to nougat 7.0 software. I was suggested by Samsung to first put the tablet on safe mode (this disables third party apps, and would reveil if an app was causing the problem) but the problem still persists. Also did a hard reset on the first tablet I had but it still done the same problem...
I always thought that this was a is problem in 7.0, and was addressed in 7.1. Hopefully, when the next major update comes out, this issue will be resolved.
Oh come on Samsung!
It's been 4 months since the first post and still no solution.
And it's a basic wifi connection!
Internet may not be available! = Samsung may not be available
Heya all. First post I guess
Edit: Gah it was the second. I have to controll myself better and not spam.
So I had the same problem and tried more or less all.
My "solution" was to disable the firewall on the router which means some settings/security there was triggered. My guess is that it's the "Smart Network connection" that trigger it if the phone have both poor Wi-Fi and 4G. It then jumps back and forward = firewall detect strange behaviour and block. That's why there are so many strange "fix" related to the router - hidden network - no security - disable 5Ghz and so on.
Can someone please test asap as I have a plan But if it's not this to test
