[Q] Extremely low WLAN signal strength

My N1 used to be able to get a decent signal everywhere in the house but of late it's struggling to even detect and maintain a solid connection with the wireless in the next room to the router.
I've got a laptop and iPhone in here and all of them have full bars except the N1, which keeps switching from data to wireless and back and can't maintain the connection consistently.
Any ideas on why?
Does it have to do anything with the radio/kernel?

Anyone?
I'm thinking of changing the kernel, would that help?

Try this first.
Tell the phone to forget the network, restart your router and see if reconnecting takes care of it. My notebook used to have this issue so it's worth a shot.
If that doesn't help, then you might look into a different ROM/Kernel or make sure that it's not a hardware fault with the N1 itself.

Could it be due to an OTA update that changed the radio?

The same happens to me, And it gets to a stage that it totally disconnects from wifi. It's really getting ln my nerves as we even got a booster and it doesn't help :?

i second that. though i don't own N1, my Desire was getting full signal last year, recently i am getting very low signal as well. other devices get full signal as usual. so probably there was some update messing up.
i'll keep on searching if someone has better info to resolve.

Radio doesn't have anything to do with WiFi. Kernel does.

i'm having the same problem...has anyone found a fix?

The problem's extended significantly. Bluetooth headset usage stutters profusely, even when I'm right next to the device.
I'm pretty sure the Wi-Fi issue has nothing to do with my router, since my Desire has full signal in the same place my N1 has one bar and is struggling to get a connection.
Changed kernels, ROMs, radios, flashed engineering SPL (I know that doesn't help, however) and even a stock EPE54B ROM. No results.

Makes no difference, I even tried flashing back to stock EPE54B (fastboot).

you may also give intersectRaven's kernel a try. the one with the wifi boost.

2.6.38.6_CAVS-CM7_CFS_20110517_2251 is the one I'm trying.

Nope, Wi-Fi range still the same, Bluetooth still stuttering on the new kernel.

[Q] Any Issues with WiFi

Loving the phone really, one thing i have noticed is when ever im downloading or uploading large files through my home WIFI after a short period the phone disconnects from the network and i have to reconnect manually. Any ideas is anyone else having the same issue. All my other devices are fine

Same thing here, but it reconnects itself - just losing the connection for 1-2 seconds. It happens sometimes even when browsing the web. Most likely some kind of software bug.

Had similar symptoms when playing with the phone at work`s WiFi (1st day of usage). On my home WiFi nothing wrong at all.

Make sure that keep WiFi on during sleep is always.
Or the WiFi will turn off the moment u turn the screen off

I found that WiFi is one of the most power draining things on phones. The best thing would be to switch to mobile data while sleeping and turn wifi off during that time.
That way you can still receive everything, but since you're sleeping you will barely use any data at all.
To bad the phone can't do that automatically.

I'm getting frequent wifi drops in my home (netgear router, wpa psk security) and its also affecting other devices in the house! Other wifi networks I've connected to seem to be fine, no issues whatsoever. Sometimes it'll say its connected, but no data, other times it will disconnect entirely.
This is a VERY strange problem and the fact that its affecting the wifi connection to other devices is even stranger.

Just an update on this, I returned my phone to P4U this morning as the wifi thing was annoying me and the phone has eaten 823mb of mobile data in one weekend even though i had mobile data turned off and connected to WIFI, The handset said i used 115mb and Voda said 823mb. not the only reason i returned it but it needed changing. So got my new handset up and running this afternoon and im set up and i been downloading all my files and apps with out any problems.
So looks like i had a dud phone first time around.

Getting the same problem too. All my other devices (Nexus7, Ipad, PC) can connect fine to my wireless home network (fibre). But when I start connecting my Xperia Z to the wireless network, after 5 mins, my Gateway will hang, and restart itself. Happens all the time without fail as long as I have my phone hooked up to the wireless network.
Anyone else facing this problem?? I'm kinda at a loss now on how to solve it. Tried adjusting settings on my wireless channel too but doesn't seem to help. Any help will be greatly appreciated!!!

Ok, so i reckon this could be an issue with not having a static I.P address. Gonna change it tonight when I get home and see if the problem is solved. It's either that or it may be trying to connect to a port thats used for something else? Have ports assigned for my Xbox ect. I'm not too knowledgeable about these things so any other suggestions are welcome. Not too many settings on the phone unfortunately so the problem has to be solved using the router I'd say.

I have static ip set up since the beginning, and I also have the problems. Only my problem seems to stem from 2.4 GHz/ 5 GHz (if this is even possible). 5 GHz is the preferred one, but this one seems to be out of range sometimes and it switches to mobile data. The 5 GHz is then out of range, while the 2.4 GHz is not. Very strange.

Ive found the Xperia Z has held on to a 5GHz Wi-Fi signal better than any other device I've used before, but the 2.4GHz can often disappear...
Very odd, although at home I am quite happy that 5GHz works better as there's far less interference from local neighbours. Perhaps that's causing the problem - in that the XZ isn't so well set up to cope with other routers on the same Wi-Fi channels??

The reach of my 2.4 GHz is at 75%, while 5 GHz is at 50%??? Strange.

I would always expect 2.4GHz to carry further, and so I am surprised by my experience too.
In my case, there's only 1 5GHz router visible other than mine, but countless 2.4GHz ones. Not sure why that would make the XZ drop (and sometimes even lose) the connection - but that's what seems to be happening.

Xperia Z no wi-fi without SIM
I have a different wi-fi issue with my Xperia Z. It does not connect to my home wi-fi when there is no SIM in the phone. It just says that the network is out of reach. When I pop in the SIM card, it connects automatically. Actually, all the hi-end Sony phones I tried recently do this (Ion, T and more). I've been looking for a solution here on the forum, but didn't find any helpful topic. But maybe I was looking wrong. Does anyone know, what to do?

I think the obvious answer is put a SIM in there... and if that means getting any old SIM and cutting it to size, even if it's not registered on any network, then do that.
I wonder if it the phone is looking at the SIM to identify the country, and therefore what channels can be used? I say this because when I first used the phone (without SIM) I also had problems [router not showing up in a scan], and my router is on channel 13. I then put in a SIM and at some stage did another scan and it found my router.
Is your router perhaps on channel 11, 12 or 13?
I know it's a long shot, but who knows?

Interesting point, will try to investigate with the channels. And I may also try to dig out some inactive SIM, thanks for the tip... The only thing I found is, that the problem obviously appears only with the WPA2-PSK security. With WPA, its all a-OK...

If you look inside the build.prop
The wifi.channel is not assigned,maybe this can gives you an idea guys.

[Q] Suffering poor WiFi performance? - Lets compare!

Hello guys,
do you also suffering from low WiFi reception like mentioned on the following sources:
Thread in Official Sony Forum
[...]but the real kicker on the SP is WiFi reception. Abominable, horrifying, atrocious -- all valid words to describe the range at which it'll stay connected. We assume Sony will be able to address this with some kind of future firmware tweak, unless the antennae were lifted from the back of a truck in Shenzhen in 2007. When connected, the signal remains solid, but at 20 feet away from a router with one wall in its path, it's incredible to see it just about maintain a connection.

Summary of Engadget Hands on
It would be great if you could do some comparison of signal strength between Xperia SP and another phone on the same location and post the signal strength of both. You can see signal strength with this app: https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer
Thank you!

For me the range isnt that important, it's the fact that the wifi suddenly turns off by itself and it wont reconnect even though I was standing beside the router. I had to forget my home wifi then reboot the phone to get it to work again. Sony really needs to work on their software

The range kind of sucks, but the speed is unaffected. Would be nice if it can be improved though. Never got disconnected before.

I faced same problem as javidben. There is no problem with wifi range. I get almost full signal 10 ft away with 2 walls in between.
The problem is random disconnections. When disconnected, the phone remains disconnected from wifi anywhere between 2 mins up to 15 mins, for no apparent reason. When I just visit Wifi settings, it re-connects to the wifi network immediately. Very irritating indeed, having to do this from time to time.
Also, sometimes when I checked on my wifi router, I saw two entries (having same MAC address) for my Xperia SP in the 'connected devices' section. I was thinking this might be a router problem, but my Note 2 connects fine to the same router without any of these issues.

I'm connecting to 802.11n and I haven't experienced any problems with range, disconnects or throughput on my XSP.

I have the exact same problem on my Defy+ running Android 2.3.7. I always thought this is an Android bug. So I think It comes from the power saving function (see Wi-Fi sleep policy) not working properly all the time and is not a device specific problem. Am I right?
On the other hand Sony has implementied its own power saving function (Stamina mode), so I expect this should not happen if Stamina mode is turned on.
Greetings

I turned on Stamina mode, and tested over a period of 12 hours, using it intermittently, and disconnections are not happening any more
My Note2 is connected to Wifi all the time, but I did not see any disconnections, so looks like it may not be a generic Android problem.

I'll try this stamina mode and post here the result, also Xperiancing wifi dropp off,

Let's hope that this will solve the problem.
But of course, it's wierd that stamina mode can make wifi more stable, because stamina mode auto turns off wifi when phone is in standby mode...

My SGSII and SGSIV have not any problem with the same router. Besides, whether or not I 'd buy a new router, I couldn't ask cafes and other access points change their router just because xperia sp has wifi issues...

I have absolutely no problem with signal strength or deconnection.
I'm using my phone on different routers (home, work, friends, ...), no problem at all.
Xperia SP C5303.

there was a little issue with the wifi network on .211 fw
but upgrading to .284 solved it. now i have full bars everywhere. :good:

For me, I am facing exactly the same problem as some of you. The range sucks, I am only 15 ft (5m) away from my router with a door, and I get 0-1 bars only
Secondly, the WiFi does switch off randomly, but when I go to the settings and check, it connects again.

dams SONY same probleem
my SP laggy and disconnected.

Seems like it's common problem then, I thought it was just me..
The Wi-fi seems to be really wonky on the SP, I've tested it sitting on the stairs beside my router for a while and it fluctuates between full and 2 bars of signal is less than a meter distance..
I've also experienced random disconnects but I think that's something to do with Wi-Fi power saving of some sort turning it off when it doesn't think you're using it.. Even if you're mid conversation with someone on whatever social media site or IM app...
Hopefully it can be fixed by Sony pushing a software update, which if it can I assume will be pushed with the next iteration of Android.

It helps I think.
My understanding is that this is the level when the phone decides that wifi is too weak and it should switch to a data signal.
I don’t suffer from range issues – the SP has as good, if not better range than all the other wireless devices in my house. However connecting in the first place can be a right pain.
I had an xperia ray before and it also did what I’m about to describe (but connected more reliably) – in essence when wifi is ‘connecting’ the signal strength will go from excellent/good/fair to poor or even nothing. It fails to connect and I’m told there’s an authentication issue.
This tells me that either my router reduces its wifi signal, or my phone is less able to receive the signal during this stage. As my router is old (6/7 years), I’m inclined to think it’s the router – Sony probably test their devices on more recent hardware.
With these things in mind what this tweak does, is hold on to the wifi signal for longer before switching to a data connection, making connecting to wifi more likely.
In my case after applying this hack the signal still drops whilst ‘connecting/authenticating’ but connects more frequently, and the signal goes back up again once connection is made.
I must also say that wifi problems are not unique to Sony devices and having had a look elsewhere for a solution I discovered that many other phones, from a variety of manufacturers, have similar issues. One of the big US Universities even wrote reports about how the Android OS was at fault for overloading their wireless network with repeated DHCP requests.
Anyway before you apply the tweak try enabling ‘auto IP support’ in advanced wireless settings. Similarly it doesn’t make sense to have ‘avoid poor connections’ enabled.

It does work for me

Thanks for the answers. I have been testing this fix and i can say it works for me. Where i had 1 weak signal now i have 2 or 1 but a steady one. Now i can move in my house without losing WiFi.
Remember that you can change -100 and test it with more (-300) but I supouse the battery will last less. Otherwise you can change to -90 or -95 if you think WiFi its enough good.

Very good. Saw significant improvement in the areas of the house that I had a problem with the connection before. C5303 on 12.0.A.1.257.
Thanks

Hi guys,
did anyone of you have this problem ?
the internet connection speed is ridiculously slow. i got only 0.12Mbps on upload and download. on my signal i got H+ connection.
i verified that the APN is correct for my telco... what is going on ?
i heard from other forums, T systems got this issue with the Z... coz they say the T system is half HSDPA and half LTE.. which either way not getting full signal....
anyone ?

nope. it's your telco

on my other phone... Xperia S..... exact same APN, exact same sim card.... i got MUCH FASTER speed.. even it's not H+.....

not true, I can confirmed this phone's wifi is working much better than Xperia S (tested both with 300Mbps wifi ap), also Xperia S wifi is not world wide supported (EG. my country ) but this phone seems to have default support.
