suddenly my WiFi range has decreased. Even if i am very close to router i don't get full signal. its not a router problem because other phones work fine ... what should i do?:crying:

Wifi reception issue?

Does anyone experience wifi reception issue on Samsung galaxy s II? I am in my friend's house and the reception is very poor. Yet both my laptop & iphone 4 has no problem. Is there some setting that I can fine tune the phone?

I do get that after having the display off for a while with no network activity, it's usually solved by disabling and enabling the WiFi. I think a more permanent way of doing it is via the advanced WiFi settings and setting the WiFi to never shut down.
Just purely basing on the signal bars, on my S2 it only gives 1 bar compared to a laptop/iphone4/ipad/itouch where they get even max, but at as I increase the distance the other devices start to drop on signal bars while the S2 keeps the 1 bar, out of all the devices the S2 has the shortest range dropping off the connection while followed by the apple devices about a mere 1-2 feet more, the laptop has about a meter more of range.

Check your WiFi sleep policy under Advanced Settings.
Yes, the WiFi signal bars strength of GSII is low compared to other phones I've used, but don't know if that affects the speed or not.

do u have slow download speed tooo ??
The issue is: All the antennas are on the back bottom side of the phone (where the embossment is). When you hold it in your hand you screen all the antennas and as consequence GSM, WiFi and Bluetooth reception and transmission become poorer. Just try to hold your phone by the top side and you will be surprised with all signals quality improvement. Good luck! That's an antenna's design fault, IMHO. You may check WiFi networks strength with WiFi Analyser app.
Try also to check TX power with WiFi TX Power utility (requires iwconfig to be installed). By default samsung uses 32dBm (max). For home use 4-11dBm is enough. Probably you have 4 dBm set up and it's not enough for your conditions.

I don't even know I can adjust the transmission power. I have installed Wifi TX power utility but like what you said, it requires iwconfig. How can I install iwconfig? I am using Litening Rom with Ninphetamine-2.0.5 kernel.
Thanks.
Hi there,
Here is the zip file. Install it as zip update through CWM or CWM recovery. If first attempt is failed, just try again.

High frequency radio signals to not travel very far in water at all, and they cannot penetrate the water from above either....... That is why submarines use Low Frequency (LF) radio signals to communicate....

[Help]Galaxy S3 wifi problem !!!

Hi !
I don't know why but my S3's wifi gets wierd problem. Yesterday I flash back from CM13 to CM12.1 with Boeffla kernel and then I flash ArchiDroid V3.15. When I connect to wifi it says "saved" and "connecting" all the times (still get the high signal). After trying many time it connects successfullly and I download a soft and troubleshoot it. It says:
- Link speed: 5Mbps
- 802.11b
- CCK
I can make sure my router provide 802.11n (2.4 and 5GHz). I tried to connect to other SSIDs and get same problem. I tried to stand next to AP and , whoa, it connects fast and downloads at full speed. But when I stand 5 meters away problem occurs again (still get high signal). I think maybe the antenna is the problem so i check the pin and use isopropyl to clean it and the wifi module but still get the problem. I don't know whether software or hardware problem. Please help ! (That is the gift my mother gave me in 2012 and i love it so much. And sorry for my bad english, i'm vietnamese).
Have you tried a static network setup?.
Have you rebooted your router and phone?.
Are you connecting to a gateway router?
When standing "5 metres" away is there any obstacles between your device and the router?.
It is possible to have full signal yet be on the very edge of the coverage area. The wifi signal reception will be stronger than the transmission as the router has more power available to it than the phone so the phone will see the router but the router can't pickup the weak signal of the device..
Another possibility is a broken aerial or faulty wifi module.

I've tried all even turn off and remove battery for 2 hours. When I standing 5 metres away there are no obstacles between me and the router (My router is TL-WR4300 with OpenWRT). My S6 and A7 can download at full speed when i'm standing very far so i think it's the phone problem.
I use logcat to see what's problem and it said "cannot lock location". I tested the bluetooth and it works well.
Have you tried the WPS Push Button?
I also flash install a modem Firmware Update via my TWRP.
I'm having trouble uploading but it is easy to find.
It's called "d2vzw_MF1_firmware_NE1_modem.zip".
Just a thought...

Wifi signal problem,very weak

Hi experts and xperia users.
I went thru this forum and looked for the same subjected question but had no luck.
Pls advise me how to resolve my wifi problem. I stood very close to a hotel access point and my m4 only discover 2 bars of signal,compare to my xi***I it got full bars. Wifi analyzer said 30db but m4 only 50 something
I tried move to another space in my home and school, restaurant with various AP brands my m4 still got bad signal,even the M4 placed very close with AP.
Pls don't tell me to make static IP, or change AP configuration.
Pls help.
Maybe your m4 has problem scanning wifi.
You really need expert to help you out.

I do need it but not sending my phone to sony service center local support, extremely worst suppot.
rest factory your phone, Go to Settings >WIFI >advanced wifi > set WIFI frequency band in 2.4 GHz only... or just 5GHz.

Probably... I had exactly the same issue... veeeeery poor signal.
On rear(left-up side) are two plates, which conecting to wifi antena. I think that are disconnected. I resolve this by replacing rear cover.

Thanks for ur reply. I attach my m4 picture from back side.
CMMIW, where are two plates you mean, @outofmemory13 ?
And you did replaced the whole back side cover?

After replacing rear(back) cover Wifi works perfect. btw. I've bought black cover(my M4 is white) - looks awesome

I tried to repair this w/o replacing - Yeah, it worked, signal is better, but still poor. Cleaning the plates gives no results. Idk why.
It's not hard. After replace m4 is still waterproof (tested).

I cant open your image, anyway i sent you PM.

@outofmemory13 finally i am able to open ur image. However it is not clear enaugh for me,sorry. So:
1. Is it located at top left of the back side?
2. You replaced the back cover and wifi signal work better?
Exactly.
on the back cover there's black sticker - this is NFC antena shared with Wi-Fi.
w/o antena the wifi works... just like IrDa in old phone So... That's why I'm think, that is problem with connection between cover and main PCB.
The antena maybe is damaged by default. Also I forget to mention that the antena maybe doesn't adhere into cover(check this by pressing this place* with little pressure - if signal is better - let me know)
*top left > 1cm down.
It does not work for me, even I take off the rear case (without case) no improvement, still weak.

Yeah, without the rear case it'll works like this.... even worse.
1. use a multimeter to check that two copper plates have around 0 resistance.
2. It can be weird, but try add some tinfoil(into the plates) to improve connection between cover and pcb. Carefully. And check again.
If doesn't work - it's a problem with Wi-Fi sensor. Unrepairable.
I've fixed 3 M4 with the same problem so far. Can't belive, that in this case all my instructions aren't working, maybe there's another issue, I guess... Anyway, check it and show the result.
#I don't like English... case, case... the same words and another meaning...
I have no luck on this and plan so sell the phone thank you all for the advices.

Wifi disconnecting?

Hi,
Long time member, but rarely post.
Xperia 1 is my 4th Sony phone and I'm having some problems with the WiFi disconnecting.
Since I've had the phone my WiFi keeps disconnecting. The phone can still see the network on the WiFi settings page, but I have to reconnect. Anyone having the same problem?
On previous Xperia there was an option to turn off the WiFi when the screen switched off, which I always unchecked. But I can't see this option (or anything similar) on the Xperia 1.
Love the phone otherwise, emulators, PS4 remote play and everything I want it to do it does seamlessly.
Thanks in advance.
maybe a different issue but I have a problem Wifi gets disconnected whenever the upper part of device is covered with my hands. This happens often when I hold the device horizontally.
No issues with my Wifi. Everything has been solid so far. I use Googlw Wifi mesh APs.
Maybe you have auto network switch on?
Also when I turn my phone horizontal and cover, I do loose 1 si gle strength.
Same here .. I sent back Xperia 2 week ago and they sent me another One.. now I've issues with Wi-Fi, camera focus sometimes go Crazy and also 2x camera doesn't work properly, in the camera preview when you use 2x Lens It looks blury..

Unfortunately, my phone already slipped out of my pocket and now has a small crack on the back. Highly doubt I'll be able to return it and get a swap if its damaged.
The WiFi problem only seems to happen at home. No problem with my old XZ Premium or the wife's phone. I've reset the router, forgot and reconnected to the home network but the issue still persists. Not a huge issue really, just slightly annoying.

Unfortunately for me, it is, I often leave airplane mode and if it disconnects I lose notifications, looks like it doesn't reconnect automatically, I have to do it
Got to say the Xperia 1 wifi reception seems weaker than my previous phone OnePlus 5. But my wifi never disconnect itself when the signal is strong enough. Only happens when the signal is very weak.
Have you tried messing around the wifi preferences setting?

Yes, after 2 defective units, I ask for a refund, I get one plus, sad because I like a lot Sony apps like album and camera.. but then again sucks there's no hdr option in the camera
I had a spell where this was happening as well, I reset the wifi router and "forget" the network in the phone and it has been much better since. Like others have said here, the wifi strength is not as good as on all my previous recent Sony phones for some reason.
I have this issue as well. Coming from Xperia XZ, I can confirm WiFi seems to be not as resilient on the Xperia 1. That said, at home I have a Google WiFi mesh network and is rock solid, its only at work that I have the disconnect issues.
At work I can see my phone will connect to 2.4Ghz with good/excellent strength, then it tries to hop to 5Ghz where it see 0-1 bars and milliseconds later it's a coin flip between disconnecting WiFi or failing back to 2.4ghz. This is the endless loop that I'm in.
So to me the issue is the phone is overestimating the signal strength of the 5Ghz connection, and getting burned each time it attempts to use it. I don't know enough about WiFi protocol but it seems plausible that the strength could be different once actually connected. I'm not sure the answer to this, but I do believe this is more or less the root cause.
HELLO wifi problems
Hi all,
I have a similar problem
I usually keep my data switched off ( at home) and WiFi off when not going online
so throughout the day I switch WiFi on and off like 20 times, 8/10 it connects but for some reason it hangs sometimes.
Quite annoying, I have auto connect on
This never happens on my XA1 ultra
Any solutions?
PS. Software repair, firmware update, factory reset, WiFi reset all done, but intermittent wifi connection persists
I am mostly online in two networks one is a mesh the other a single router.
I always have troubles with the mesh but is not exclusively to my xperia, there are troubles with iPhones and Samsung has connection issues too I think it's a general problem with mesh networks.
I didn't find any solution to this.
