Wifi Signal Strength - Android Q&A, Help & Troubleshooting

Hi,
I have searched but unable to find something similar to my issue.
I have a Asus ZenFone 3 Laser - ZC551KL.
Background:
Have had the phone for about a year but haven't gotten around to transferring SMS etc from current phone so it is currently only used as a tablet / watching YouTube etc. So not used massively.
On Thursday/Friday I came home and was unable to connect to my WiFi. When I restarted device I could connect but noticed Poor Signal and slow internet. It was now I noticed that none of our neighbouring wifi was showing.
I tried:
Restarting routers and phone.
Reset network settings
Safe Mode
My wife has the same phone and able to see all the normal networks. It doesn't seem to be an issue with speed once connected but I now need to be within about 5 meters of the router to connect.
I am curious if anyone else has had this or a similar issue / how they fixed it?
If people think think it might be a hardware or software error?
Possible fixes.
Android 7.1.1
Android Security Patch - 05-JUL-2018
.Model (in settings) ASUS_Z01BDA
Thanks in advance for your time and help.

[Q] Connection issues

Hey everyone, I got myself a Z2 recently and have been very happy about it for the most part. However, some things seem to not function a 100% the way it's supposed to.
Some times after it's been to sleep and I try browsing online with it using either 3g/4g or wifi the phone says it has a connection, but nothing loads. All I have to do to solve this is to refresh the wifi/3g connection manually, and then it works. It's rather annoying to always go through that procedure every time I want to use my phone, so I'm wondering is there anything I can do about this? Or anyone experienced anything similar?

I have the same issue with WiFi while the phone sleeps or is active (no probs with mobile data though!), but I was not able to determine whether it's my router, the phone, or a combination of the two (though I have a hunch).
When I'm in my room which is unfortunately the farthest from the router, and the connection drops, my Z2 is not able to reconnect on its own. Have to disable/enable WiFi or else it's stuck in an infinite loop of connecting and obtaining an IP.
Now, I'm fine with a dropping connection occasionally given the distance and the... quality of my router. However, my laptop is able to reconnect automatically.
I have tried lots of possible solutions: WiFi sleep policy, static IP or DHCP, disabling/enabling WiFi optimisation or Auto-IP, switching WiFi channels, and various WiFi fixer apps. Nothing worked.
My guess? There is a bug in the stock firmware that makes the phone unable to reconnect if a connection is forcibly dropped . Pair this with a crappy router and you have a recipe for inconvenience.
Unfortunately, I have no spare router to confirm this, and with the bugs in CyanogenMod I am reluctant to flash for now.
Also, I am sure this is not a hardware fault of the phone in my case since I notice this behaviour at home in my network only.
Do you guys possibly know where I could find some logs related WiFi? I wanna get to the bottom of this.

[Q] i9300 wifi signal/connection issues - Murata vs Samsung module

Hello team,
My Samsung Galaxy S3 GT-I9300 (international version) started to have wifi problems after stock update to 4.1.2. After that, I´ve tried many software and hardware fixes, including changing the wifi antenna cable. The result was the same, so I decided to try custom ROMs and came straight to CM11.
The wifi signal is very weak, and I can only connect from a few meters from the router
Installed CM11, full wipe cache/data/dalvik and still the same problem, weak wifi, connection only from if close to the wireless router.
Reading all the forums on XDA and CyanogenMod, I found the wifi-fix patch, which writes "murata" on the /data/.cid.info. This fix brought me powerful wireless signal, and now I get full signal bar to my router and even see many neighbor APs... but I am not able to connect. When I try to connect, type de password and than it just goes back to "Saved, protected by WPA/WPA2". I´ve also disabled authentication on the wireless router, and the result is the same. It won't connect not even to open networks, although I see strong signal.
Deleted the wifi_fix patch (delete ¨91fixwifi¨ on init.d, delete ¨.cid.info¨ under /data and rebooting), and went back to old status: very weak wifi signal, but able to connect (associate) if I´m very close to the router.
Turned wifi on and off, airplane on and off, captured log on "Murata" and "Samsung" modes...
Strange is that my wlan mac address is 88:32:9b:xx:xx:xx, which seems to be Samsung, but the Murata brings me powerful signal (although I cannot connect).
Well, I´ve tried many solutions so far, but that´s how far I could go...
Can anyone provide me some clue to solve it? I would be very thankful to have wifi back to my phone.
Log files are in attachment
Murata log (strong wifi, not able to connect)
Samsung log (weak wifi, able to connect when very close to wireless router)
Thank you all!
I too have only a range of 3 metres, I have 7 routers in the house because of this, yet I have less than 15% coverage of the house with this device. To put that in perspective, an HTC One X and Atrix 2 has 90% coverage with 2 routers. I'm 1 metre from the router in my room and I've got 1 bar, sometimes 2 briefly.
[Edit]
Woah, I tried the fix from:
http://forum.xda-developers.com/galaxy-s3/help/cm9-i9300-advice-t1898004/post41394293
Seeing as it can easily be reverted, it displays very high signal. What I'd expect. But it doesn't let me connect either. I also tried CM10.1 like the people who it worked for, it didn't work.

[Q] Crippling Wifi issues - Please help

Hello everyone,
I'm a longtime lurker of XDA ever since I switched from my Palm Pre (RIP) to an HTC Evo 3D. I created an account finally to post this question and I'm hoping someone can help because I am at the end of my rope.
My Nexus 9 has a wifi issue that cripples my entire network. First, I'll give you the details of my configuration and the problems I'm running into:
Running an ASUS RT-AC66R on Centurylink DSL. I have tried both the 2.4 and 5GHz bands. I have tried multiple channels per band with no effect on the issues listed below. The 5GHz band is currently disabled.
Unless I am am running the factory image that came with the N9, my wifi connection will almost completely dry up across every device on the network when the N9 is connected. As far as I know, this only happens on my home network.
Restoring the N9 to factory settings - which I have now done twice since purchasing it on Nov 3 - eliminates this problem almost entirely until I install the OTA update. This problem happened with both the day one patch and persists in the recent update to 5.0.1.
If I am playing my PS4 or streaming Netflix (or anything that requires a connection), I notice the connection speed rapidly drops to somewhere in the range of 0-5 kb/s as soon as my N9 connects to the network. When I deactivate the N9's wifi, the connection returns to normal speed immediately.
I am still connected to the network when speeds are low, but data crawls. I am able to connect to the router's config page and can see that traffic caps out at about 5kb/s down and 60 kb/s up.
Here are some of the fixes I've attempted, which all failed to produce results:
resetting the router
resetting my modem
disconnecting all other devices
switching channels on the 2.4 and 5GHz bands manually
updating the firmware of the router
changing the network name
changing the network password
changing the network security type
I am typing this after having reset my N9 to factory settings for the second time to confirm that the issue lies within one of the firmware updates. Can someone please help a networking noob figure out how the connection of one device quickly (within 15 seconds) halts all traffic?
I should mention that the exact same issue was present on my N5 earlier this year (long before Lollipop arrived) but that it eventually worked itself out and stopped hijacking my network. Unfortunately without mobile data on my N9, it is essentially useless until I figure out the issue.
Thanks in advance for any help!
The first thing that came to mind is an ip conflict. Have you tried changing to a static ip on your nexus 9?
Edit: Also when your nexus 9 is connected check and make sure the ip address on your other devices jives w/ you router (you may need to make all devices static until you find the problem) I had the same router as you and i had a network switch that was throwing odd ip address to devices not even attached to it...
I updated to 5.0.1 again and didn't have any issues this time around. I went ahead and set a static IP anyways but I'll report back here if I have any issues. Thank you!

Sony Xperia Z2 Tablet (SGP521) Wifi and Bluetooth problem

Hi all,
About a month or so ago I started to experience issues with with the Wifi and Bluetooth on my tablet.
At this stage I'm unable to switch on the Wifi or the Bluetooth. I'm only able to to use the cellular connection. When you try and enable the wifi connection is shows that it's trying to scan for a network, but it actually never switches the Wifi on. At times it actually pauses for a few seconds after selecting the Wifi option. Then at times it just doesn't do anything when trying to activate the Wifi via the quick pull down menu.
From what I have read it appears to be a hardware problem, but then I also saw comments that it might just be a software issue.
I was rooted at one stage and in my desperation I did a OTA update to the latest 5.1.1 release to see if that will help, but it did not.
When I was rooted I did a factory reset via TWRP, but that also did not work.
My device isn't under warranty anymore so RMA isn't really an option.
However I would like to check with the community if there is anyone else who had this issue and managed to get it fixed.
Is it a hardware or software problem or even a bit of both?
Would one be able to possibly replace the WIFI and Bluetooth radio in the Z2?
I normally use the Z2 for media consumption whilst at home over the wifi connection and would like to see if it can be fixed without costing an arm and a leg.
Your help or suggestion will be appreciated.

Wi-Fi Connection Problem

Hi All,
I just received a replacement for my V10 that suddenly died and I'm now having Wi-Fi connection issues.
When I brought it home yesterday the phone was still on 5.1.1 but updated overnight to 6.0 both experienced the same issue.
I have not rooted my device yet but will in the near future.
I have 3 different access points in my home with different id for each.
I can connect to one of them but not the other two.
When I try to connect it I eventually get a WI-FI connection error, or the connection is labeled disabled, or the connection doesn't connect and just shows saved.
I have tried:
1) reset the router
2) changed the password
3) changed to an open connection e.g. no password
4) forgotten then connection on the phone
5) restarted phone
none of these have fixed my issue.
Anyone have similar issues?
Anyone have any ideas for a fix?
Thanks you all for reading my problem.
steve
Just started having a similar issue yesterday. Stock MM, no root. Factory reset had no effect.
Maybe you can join my thread, I have problem with wifi also. You can check if we have same issue and may try my workaround http://forum.xda-developers.com/tmobile-lg-v10/help/wifi-mac-address-changes-reboot-h90120j-t3470140
I actually just noticed this on my phone yesterday. It seems to happen to me when the wifi signal is a bit weaker (but should still be able to connect). My wife's V10 didn't have an issue though. Haven't find a solution yet, but my wifi would also not find any connections after it would disconnect and have to rescan to locate any networks.

Have you tried to do factory reset?
