[Q] 802.11a or 5GHz WiFi - LG Optimus 4X HD

Hi,
anyone else noticed that the Phone seems to support 5GHz Wlan ?
First I was in the "hidden menu" (3845#*880# from phone app) there I was scrolling around and discovered some 5xxx Frequencies in the Wlan test tool. Then I downloaded a Wifi-Test-App and it also seems to show 5GHz networks in the vicinity.
Anyone with an 802.11a accesspoint that can please confirm this ?
I can not remember that this was advertised anywhere. Actually I thought that it was a pitty that it cannot do 5GHz, but seems like it can.
If this gets confirmed it looks like this phone has many features that are not advertised. This wifi thingie, Glonass, maybe even it has digital TV in it somewhere ?!? :laugh:

I am using it on my 5ghz wlan at home and at work, no problems

(solved) note wifi disconnecting :(

Hi all. i have a problem with my note. on some instances if i try downloading large files(for games or navigon maps, or just browsing on some sites, etc) after 10 15 seconds the wifi adapter shuts down/resets and the connection is lost. the adapter restarts and connects to the wifi in 2 3 seconds but is very frustrating to try downloading something many times before succeeding. anyone else has this problem? i searched the forum but didnt find anyone else with this problem. any ideas as to what is causing this problem?

Re: note wifi disconnecting
Hmm. Try changing the router wifi settings to transmit only b/g and retest.
Had the same issue, please tell us what version and kernel rom you are using?
->I had only when using CM, on stock GB and the XXLSC roms, I did not encounter this problem (also with cm 10.1 I seem to have a stable connection again)
**I do want to note, that it can't be possible to have a worse connection when on CM vs TW, but I have experienced it this way. So I can onlyh draw my conclusions from that...(I don't have any developer knowledge whatsoever)
Re: note wifi disconnecting
I would start by un plugging the router and plug it back in.

baseband version: N7000 xxlpt. kernel version N7000 xxlq3. android 4.0.3. This issue was present from day one. but never tried downloading large files from another router and my htc legend never had this issue with the router. will try to see if the router is the problem today and get back to you. tx to all in advance

Try this:
Dial *#0011#*
Press the menu button on service mode screen
Select wifi
Turn "wifi power save mode" off
It seems like this is only working on samsung roms. I'm on CM10.1 and I have to dial *#*#0011#*#* to access the service mode.
Also there is no wifi entry in the menu.
Re: note wifi disconnecting
just downloaded a 700 +mb file with no problem. i set the router to b and g only. seems it was the frickin router. tx a lot to all 4 ur support.

CHanging to b/g works
Hi,
I have router DIR 855 and had the same issue with my note. Wifi kept disconnecting whereas all the other devices at home stay connected. So it was clear that Note was the one that had the issue. Changing the 2,4ghz to b/g setting helped but I would like a stable connection on my 5 ghz band and that one keeps disconnecting. Any idea how to fix that? I am using NAS and the speed is much better when using 5ghz instead of the old crappy 2,4ghz.

For me too 5GHz is not stable on note... Why not use the router on Auto and then use the settings on NAS to use only 5GHz
Please explain

Hi,
Can you please elaborate on how to do that?
My router has two different bands and it cannot switch between the two. What do you mean by NAS setting?
Depends if your router can run simultaneous dual band.

WiFi issues on stock

I have issues on Wi-Fi with my one where with my Samsung glide no problems . I have a Belkin router wireless N and it normally works fine but with the one I get occasional drops and reconnects. Anyone else have this issue. I am on stock rogers. My Wi-Fi has security enabled as well.

Did you turn on Power Saver and Sleep Mode? Click the Power Saver mode in the Power menu in Settings. You can select what Power Saver controls. Untick Data Connection, and if you want, turn off Sleep Mode as well.
I have noticed some issued. I have the developer edition and upgraded from a nexus 4. There seems to be issues with the One releasing wifi and reconnecting to data or vice versa.
In some cases, i know i am clearly out of range for a wifi network, such as the top floor of my office, yet it picks it up and connects without data since i assume i am out of range. For now i just manually control it as its pretty rare, but fir sure not something i have ever experienced before.

Agreed this is what I am seeing.I have disabled power saving and the other option to turn off data when sleeping and yet periodically the wifi just drops as I am viewing some wifi video streaming. It is weird I switch off the WiFi and use data and all is fine. I do not know if it is an incompatibility with my router. That's why I posted here to see if anyone else is seeing similar issues.
Also is there a way to set a manual Ip? was wondering if that may help as have heard issues of other phones having issues with DHCP via wifi.

I ordered a new AC router and will see if that works better and if I still get wifi drops. I am hoping it is my old cheap router giving me issues.

Well I got the ASUS RT-AC66U and now the Wireless 2.4GHZ works great but the phone will not connect at 5Ghz, so much for AC that only operates at that frequency. I heard other people are having this issue as well from my searches on this forum and the web. Kind of sucks that my router has the latest firmware and still has this issue with this phone. I did notice that there was a beta firmware on Asus's site but I am iffy on trying a Beta Firmware on my Router when all other devices are working great and so is the phone on the 2.4ghz. Great range with this router as well. Sucks that I can not use the 5Gz on the phone though. Tried on 2 other Devices that support 5Gz and it is working great on them. I gave 2 different names for the 2.4Ghz and the 5Ghz to tell them apart, but no go on this phone.

here's my take on the whole wifi thing with htc one. either the wifi chip is too picky or it's too new for the older routers. i couldn't get a wifi to stay connected using my old D-Link DIR-655 router from years ago. All other devices had no problems except this phone so that's a bummer. I then picked up the Asus RT-AC66U and immediately flashed the latest beta firmware. Performance and range is flawless on the 2.4GHz band for this router. 5GHz works as well if i'm close but it just doesn't have the range of the 2.4GHz for this phone so I've been sticking with 2.4GHz.
I actually wanted the just announced RT-AC68U but couldn't wait any longer as there's no eta on the release for it.

I used to have a Belkin Wifi-N router cost me about 40$ on sale and it used to work with my old Samsung but could not connect and stay connected on my One (Single was not to strong on top floor of house as well). It kept dropping WIFI after a few minutes on One and was really annoying. The RT-AC66U works great at the 2.4Ghz and I am tempted to try the Beta Firmware that you are using but I hear it slightly drops the range on the 2.4Ghz and all my other devices (WD-TVlive) are working great streaming 1080P from 3 floors up (Routers in Basement). Question for you, since you flashed the Beta firmware and can connect at 5Ghz are you hitting the 400Mb speed when you connect at close range. If you click on your connected network on phone it shows you the connection speed.

unfortunately with the beta firmware on 5GHz band, the fastest i am able to connect with this phone is around 87Mbps and it still feels slow compared to 2.4GHz. mind you this is me checking the speed by standing right next to the router with my phone. on 2.4GHz the fastest speed i can get is 72Mbps but the range is great. i hope asus is able to release newer firmware that will help increase the speed and range of this router at 5GHz but it's probably not possible. i still think it's the AC chipset/driver in this phone that's preventing the wireless from achieving maximum speed. in comparison, my dell latitude notebook is able to connect at 450Mbps at 5GHz with on wireless N. THat's with the intel wifi chipset which has always been imo the best in compatibility and performance. i look forward to the day when i can rock a smartphone with intel all in one chipset.
I am also connected at 72mb and at 2.4ghz it connects great. I am going to leave it like this. I find the range on the Asus router is amazing. It sure beats all other routers.

[Q] So about the wifi issues...

A number of people have been having issues with wifi, myself included. I keep going over my monthly data restriction. I want to know if this is affecting everyone or only a subset of people. If it's the latter, I'll call customer service and get a replacement.

Can you describe the issue a little more? Try testing your connection with Aruba Utilities.

don't know what the OPs issues are, but I just got the Moto X yesterday and it is not liking my home wifi. Every other wifi I've been on today (at work) has worked great. At home it connects to my router and shows great signal but nothing internet related will load. Everynow and then it will work only to stop working randomly. I have comcast with their ARRIS gateway.
All my other devices at home (roku, dish DVRs, iphone, ipad, GNex, laptops) work fine.
If you have a dual band router, set the frequency settings to either 2.4 or 5ghz instead of auto. I initially had inconsistent Wi-Fi functionality until I did this, now it seems to be fine. I have an Asus ac56u.

Just like tabbibus said, it shows great signal and has no problem quickly connecting, but nothing loads 3/4ths of the time. For example, I ran speedtest and it stopped partway through the upload even though it was still connected. I can't change router settings because I rely on college wifi.
So it seems like half get the issue and half don't?

The frequency setting is in your advanced Wi-Fi settings on your phone. Set it to 2.4 instead of auto and see if that helps.

[Q] Issues with WiFi

Guys, since I've bought my razr I, I have this terrible issue with wifi connection. Everything works perfectly normal, but when I let the phone idle for like 10 minutes, it's like the wifi drops the connection. The device tells it's still connected, but I get no push notifications and no navigation either. It only happens when I'm at home, and the most affected is the whatsapp. Anynone has any information regarding this?

if it only happens at home as you say it seems to be more a problem of your router (settings).

Have you got any idea of what settings I should look? Here I have an iPhone and blackberry and both have their wifi working like a charm.
Updating the firmware of your router would be the first thing to try.
Set your WiFi connection to 2.4ghz only (on your phone) and deactivate the 802.11n standard (on your router). In my Fritz!Box, i had to chose 802.11 b+g. The razr i doesn't like the n standard, although it "officially" supports it.

Can't see 5GHz WiFis

5GHz Wifi N signals are "missing" on my XSP.
While at home, my old LG 4X picked up automatically three 5GHz frequencies from local hotspots using WiFi Analyzer app. The Xperia SP doesn't display any, like the 5GHz is not there at all. Tried with all the 5GHz channels turned on in the app, as well as just a few, more common of them, to no avail. Furthermore, WiFi Analyzer is missing the 5G icon on its graph screen.
I thought it was the weak signal problem on the SP so many spoke about, but I found the WiFi performs much better at the same places and circumstances than the mentioned 4X, although at 2.4GHz. I also went to a place where I previously used a 5GHz wifi, but still nothing.
The phone is on .1.254 generic UK FW.
Can anyone help me with this?
No 5Ghz
I can confirm this. I'm on 1.205 and I can't see any 5Ghz AP. The phone is advertised as dual band, even tho I don't use a dual band router this still annoys me, My old and cheap Blu Dash 4.5 gets better speed from the router (130+) compared to the SP (74). I'm happy with the XP but these WiFi issues are really annoying.
For a fix, my uninformed opinion is, this should be addressed on the kernel or driver level, the chipset has the dual band hardware but something is missing between the hardware and our stock FWs.
