WiFi useless in my opinion on the Xperia

1. It disconnects automatically too frequently
2. I have a secure network and I have to enter the 100 digit (seems like) password everytime
3. Sometimes wont' connect at all.
The signal strength is 100% too.
Anybody else have this issue???
Is there a program that can monitor and connect automatically (remembering password) to help me???
Many thanks.

Mine is OK. Only have to enter the password once for the first time. Mine only disconnect when I turn the WiFi off via Communication Manager.

Im with craven.... My WiFi works perfectly.

My WiFi works flawlessly.
There is SPB Wireless for monitoring only.It does not help you reconnect. Good program.
Did you try to adjust the slider on WiFi settings towards Best Performance instead of Best Battery (it's on Power Mode in WiFi settings, from Communications Manager) ?
Maybe you have installed some crappy sofware that takes over your wireless settings(it happend to me when i installed some software- i don't remember it's name right now).

nope mine's ok. doesn't turn unless you specify. Reception is not bad either.

no problem with my xperia...

No problem with Linksys WRT54GL at all. Maybe you should check your router's settings.

Only twice had I needed to re-enter my WPA passkey, but otherwise it's great. Able to enjoy the web whilst in bed and a lot faster than my old P990.

It happened to me twice.
Though no problem lately.
As a little trick, you can use a text file (or whatever code protection software) to store the key and do a copy/paste if you don't want to type the code all over again.

I had this problem at first... I didnt know why it would keep disconnecting...then i figured it out..the wifi disconnects when the phone is in standby. Schaps advanced configuration tool fixed it quick and now im enjoying it very much =)

many people have success upgrading the firmware of their routers to fix
such issues

wifi working grt in my x1
once i entered wep key
now its working grt

You shouldn't use WEP, you can crack WEP under a minute now and even if you use a while "mac" list it's not safe enough since you got the MAC addresses just listening the packets.

my x1 works perfect on wifi. not loosing connection, set up the wlan key at the first time and it was saved forever. have tried it on 5 wlans and everywhere without problems... is think wifi and the gps are the only things that are sophisticated 100% on the x1 ^^

It is good only if you have a usb connection or 110/220V nearby as always on wifi drains the battery in a half day
BTW: the wifi reconnect after suspend is really fast here, almost every time 1-2 sec.

mine is just fine, my home wifi uses a 11 digit password, just had to put in once and never again, doesn't disconnect randomly, only when disable the wifi obviously.
you should check with your warranty, see if they can do something about it, cause your case isn't normal.

have you all changed it to best performance in the settings?
im sitting right next to my router...and it loses connection now? this is quite annoying. i put the slider in the middle.. i sometimes leave wifi on when im asleep at home. so i like to keep it in the middle? whats the deal?

haha...about the Xperia wifi problem,just off your bluetooth b4 u try to use the wifi.
i think xperia is sharing wifi and bluetooth in the same device support.
i been test many time....when open bluetooth the wifi is weak and keep disconnect..
if this problem can't slove it then i think u better send to service center to fix it.

I actually found a problem in the Wifi/Wireless configuration.
I have 2 WPA protected routers with long keys/passwords. I found that if I enter the keys for both, the X1 would only remember ONE of them. I tried this by trying to save the password on either one of the WPA routers, and would only remember the FIRST one entered. So if you entered a 2nd one, it would always forget it, and you would need to manually re-enter the password again. Sure, it would connect, but then after it disconnects or you leave the area, then re-enter the area, it already forgot the password again.

i dont have bluetooth on and this is getting pretty annoying..
are you guys all using best performance?

Sudden disconnections on wifi

Latley, the past two days, when I use wifi everything seams to be working fine. When I lock the screen and wait a couple of minutes the internet connection is lost. Wifi still connected but no internet running even though the net works fone on my pc.
Every app I've installed latley I deleted and I made no changes on the setting.
Does anyone has any idea how to solve that ?
Thanks

Check your Wi-fi sleep policy settings...make sure it is on "Never"
Settings -> Wireless and network -> Wi-fi settings -> Advanced (press settings button) -> Wi-fi sleep policy

yeah you need to change your wifi sleep policy to NEVER. which by the way is better for battery life compared to letting wifi sleep and switching back over to 3g for data.

I have exactly the same issue and my wifi sleep policy IS set to "Never".It didn't help at all.If anyone knows something,I'll be interested.For the time being,I don't really mind turning wifi off and then on again but anyway.

I have that problem on my Asus Transformer, which happens only, when it sleeps several minutes. One or two minutes are not enough to loose connection. Several other Honeycomb users are affected too.
I think, it's a problem with the Android Broadcom WiFi drivers, though I'm astonished, that my SGS2 didn't show this problem so far.
Both devices have a Broadcom WiFi card and it seems, that it helps to use a static IP ... it doesn't solve it completely, but it happens more seldom as it seems.

WiFi not working after extended periods of non use

So what I'm finding is that if my tab sits on the charger for a long time without using it, when I go to use it the wifi icon is gone. When I go into wifi settings, it says my network is not in range. To fix it, I have to toggle wifi off and then back on, and then it gets on my network just fine.
Anyone else have this problem?

Have you tried changing the wifi sleep setting? Worked for me, I believe it is under settings-asus customizedsettings- wifi sleep settings

really odd. Outta ideas already lol. Good luck!

I had this issue with my TF101 after not having the issue for 2.5/3rds of the time I owned the TF101. Initially I thought it was the TF101 but I narrowed it down to the router.
A) I had implemented a policy on my router to restrict the number of IP addresses it can "assign" to connections. In this case it was set to then and there were more than ten devices connected to the router making it impossible to assign an IP address to the TF101.
B) It could have just been something with the router I wasn't aware of as resetting the router always fixed the issue. Though this could be explained by saying resetting the router resets all of the connections and opens up a spot for the TF.

In Android phones you can use the secret codes
If you have the phone apk installed perphas you can use this:
WLAN Test:
*#*#232339#*#*
*#*#526#*#*
*#*#528#*#*

I have noticed that when my 300 is sleeping for a while, my email will not push/ sync. When I wake my tab up, Ive noticed the wifi icon is gone, but will come back in a second or two. Ive never had to toggle the wifi however.
And yes, Ive made sure the Battery Saving setting is unchecked to not suspend network connection while sleeping.

Nexus 7 wlan_rx_wake - causeing 50% battery drain

I use Better Battery Stats and noticed that wlan_rx_wake is causing my N7 to wake up all the time. In 19 hours, it cause awake of 9.5 hours and the battery goes down by more than 45%.
Based on Google searches, it seems to be caused by the way the N7 Wifi card interact with the wifi router. Some suggested "fix" is to use static IP in the N7, but that's hardly a solution since I cannot do that when connecting to a Wifi router that I do NOT manage. I.e. office, school, Starbucks, etc.
So does anyone have any fix, or this is not fixable?

Do you have Wi-Fi set to turn off when the screen is off?

I have not, because:
1). I have GV app and if WiFi is PFF, then I won't be able to receive calls
2). My Galaxy Note have Wi-Fi ON even when screen is off and did not have this problem.

I also have it set to always keep wi-fi on during sleep in order to continue receiving notifications. I only lose 3 or 4% overnight, so I'm sure that is not the source of the problem. I don't use static ip. Have you tried using 'Wakelock Detect' to see which app is causing your wi-fi to keep activating? I think it is an app not your settings. Maybe trying to keep updating location services?

I do, but it's not accurate, showing only that Android Systems and Maps are using, say 10 minutes time but the "Awake" was for 3 hours. So I use BetterBatteryStats instead and that's where I saw the wlan_rx_wake taking 3 hours of the awake time.
I don't use static IP, I do use static DHCP, so it changes whenever I connect to a new Wifi AP.
Do you have the following running (these are CONSTANT background data sync)
- 4 GMail accounts (push)
- 2 Google Calendar sync
Just wondering if having too many Google accounts is actually the root cause of it.

I suppose that is possible. I just manually sync my Gmail, but have google voice set up for notifications. Try turning off auto-sync one night and see if it makes a difference. If you're sleeping, you don't really need it.

Where do I change this? I use the Gmail app and don't see this in Gmail --> Settings. If I go to Settings --> Accounts, all I see is to enable or disable sync completely.

So i've had the same problem where my galaxy s3's battery has just gone to 0 in ~10 hours and i finally found the fix for it, this is what's causing it for me and might be what's causing it for you to, anyhow i'm gonna go step by step with what i did to find the culprit.
I downloaded an app called Network Log and let it log some of my traffic, i quickly found that packets where beeing sent by 192.168.1.74 wich is not any android device but my main computer and there i found the source of the problem, i was then searching around and stumbled across this post, http://forum.xda-developers.com/showpost.php?p=25876666&postcount=3
I found this line in the post,
Q: Wakelocks "wlan_rx_wake" wake up my device constantly what I can do about it?
A: The problem is neither Android nor the kernel, but the router and the (Windows7) network. In the network properties, uncheck "IPv6", disable the service "IP Helper", "Shell Hardware Detection" and "Windows Media Player Network Sharing Service", which provide ongoing Traffic. Then they scored again 98% of deep sleep.
Click to expand...
Click to collapse
and i decided to look in to it, i started the "run" command in windows and wrote "services.msc" wich then boots up you services that's started by windows, after that it's pretty simple.
Find the line called Ip Helper and stop it after that right click it and chose properties and decided the start method as inactive, after that look up the "Windows Media Player Network Sharing Service" and do the exact same thing there, this actually fixed it, my computer for some reason got stuck on sending useless packets over the network and was sending it to my galaxy s3 along with my mothers galaxy note 10.1 (no other android devices where seeing this thou for some reason) and after setting those 2 to disable i now have had my phone at 99% battery for over an hour with wifi active.
I do hope this helps and i'm gonna post this in the other wifi_rx_wake posts i can find.

Thanks for the info, really appreciated it! I will try that for my home computer, though I have a Mac (and a PC)
However, I think this won't fix the issue where I have my N7 connected to Wifi outside of my home. I.e. at work, I can't change other people's workstation settings.
I am curious what is it in N7 (or even Android OS) that makes it "respond" to certain network traffic generated by the router and/or workstation, causing it to keep waking up.

I know this is an old post, but I thought I'd just mention that you can change your N7 from dynamic IP to static IP manually for each Wifi network, without any need to change anything from your office/school/starbucks' router side.
Just go to Wifi settings, long press the name of the network, select advanced, and setup your static IP. It will remember it for that Wifi network in the future.

I wish I could. The way the Wi-Fi setup at my workplace is that I authenticate first and then it assign an IP address based on my user account and Mac address AT THAT TIME. If I change it, it no longer works. Some sort of security feature.
But having to assign static IP for EACH location is not only a hassle, it beats the purpose of DHCP.
Unfortunately, Google had been ignoring this problem, even though there are countless post on Google's own product forum.

[Q] Wifi keeps reconnecting

My S4 keeps reconnecting to my wifi for some reason. I get the toast notification saying "Connected to <SSID>" that will sometimes pop up every 5-30 seconds, but it never goes more than 30 minutes without doing it. My router is an Asus RT-AC66U. I've tried forcing 2.4Ghz only, 5Ghz only, changing the preamble (short, long, auto), changing the channel (manually specifying each channel, and also tried auto), and even manually assigning an IP address on the phone. None of these things help.
I have "check for internet service" under the advanced wifi options disabled, and also have it set to keep wifi on during sleep.
The phone shows Very Good signal quality. Using wifi analyzer shows a signal strength of between -45 to -68 db, depending on what room I'm in, so that's definitely not the issue. It even does it sitting in the same room as the router. No other devices have an issue, including my roommate's S3.
I can fix it by turning off wifi power save mode (*#0011#), but then my phone heats up quite a bit whenever I'm using it, and my battery drains at 10%/hour even when I'm not connected to wifi. So that's not really a solution.
Is there any other fix for this? It's a bit ridiculous. I'll load a webpage and it'll interrupt halfway through when it re-connects to wifi. Since it keeps reconnecting to wifi, it causes all the phone's connections to be re-initiated, and also seems to trigger Google Services to update the phone's location. This results in Google Services (NetworkLocationLocator) holding a wakelock for 1/3 of the time.

So it seems the problem was IPv6, specifically IPv6 that autoconfigures. All the wifi networks I typically use are dual stack IPv4/IPv6. What I'm guessing happens is that the phone doesn't wake up for some of the IPv6 broadcasts, and then the phone reconnects to fix this once it realizes it's out of sync. Turning off power save mode means it gets all these packets and doesn't have to reconnect.
So I fixed it by having Tasker disable IPv6 on wifi whenever it connects to a wifi network (it's re-enabled if you disable wifi or reboot). Run this as root:
echo 1 > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6
I wonder if this is just a bug in the chipset, or if it's a driver issue that can be fixed in a later update.

I had the exact same issue with mine (same router) and solved it by disabling WMM APSD in the router settings. Wireless>professional tab>5GHz drop down box>Enable WMM APSD>Disable.
A guy in the other GS4 Q&A forum gave me this solution and I haven't had an issue with it since.

I have this same issue... so when my Wi-Fi is dropping like that, I disable the Wi-Fi power save mode by dialing *#0011# then pushing the menu button and selecting the Wi-Fi option from the pop-up, the psm button is there. Fixes it every time, doesn't stick thru a reboot tho.

Hello, I'm having the same problem but I'm new to Tasker and don't know where to put that command. Would you mind showing me how to implement it please? Thanks.
Edit: Nevermind, I think I figured it out.

S4 will not store setwork
I'm running SACS Custom 7.1 with Faux kernal, and since I update to 7.1 from v7, my phone doesn't save any wifi profiles I connect to. Another thing I've noticed is no image shows up when recieving a call, so I have no idea who is calling. I got a 3rd party caller id from the market to fix that, but still a strange issue.
I am experianced with phones, but haven't posed enough here to post in SACs page, so any ideas would be helpful.
I tried looking at settings from 3minit or XPOSED, but nothing has changed since V7, so I'm wondering where to look.
The wifi profile shows up in data/misc/wifi/wpa_supplicant.conf, but only the one I am connected to at the time. If i disconnect and reconnect I need to re-enter the password.
Not important but annoying.
Thanks for your help in advance, you guys are awesome!

Wifi issue is faux kernel flash a different kernel. A module from xpose is the culprit sorry I forgot which one was it. To solve all your problems just do a clean install of v7.1 and when doing that make sure you click stock kernel or flash a preferred kernel. I dont use xpose so I dont have that problem so its your choice if you want to use it just read like 10 pages from the thread to find your answer.

I have to do this same thing and it works for me perfectly. A little bit of a hassle after reboots, but it works. I sent this to Samsung and they've opened a ticket on it (reportedly) to be addressed as they've had a lot of complaints about WiFi areas with multiple Access Points.
