Hi, i'm the owner of an "unlucky" lg optimus 2x
I've got a lot of problems with the wifi connectivity which is always really bad (i can use it only when i'm at max 30-50m far away from my router) so i guess this phone can have some problems with the wifi antenna.
I already tried to use it also with some free city hotspot, but the connectivity is always poor.
Anyone know where is located or how to change it ?
Does the 2x wifi antenna is the one located at the bottom of the phone (or that is the gsm one, or they both use the same) ?
In fact i already changed the touchscreen and the lcd pad so i think this is a faulty phone, but i'm not the first owner of this unit so i can't send it back to lg in warranty.
I already tried changing the baseband and the rom (i tried a cyanogen 7).
Now i'm using a stock v20q rom plus 1120 baseband.
Thanks in advance for any help and sorry for my poor english
Well, I have to say I dont think that 30 - 50 metres is low radius. The signal mostly depends on router and the surroinding area of router. Of course, the antenna of the phone is weaker then NTB for example.
In my opinion, the antenna is just right

Well, depending on the location, 30-50m can be quite far for wifi if you have walls in betwenn
Do you have a laptop?
If yes, can you try comparing the dBm readings from a scanner program like NetStumbler with those from your phone (use an app like Wifi Analyzer)?
For experimenting:
If your router has more than 1 antenna, try to have them in 90° angles to each other
Try other settings: b/g/n(20MHz)/n(40MHz) ot other channels: take the one that no one else has (see the output of the wifi scanner) and the standard ones (1,6,12)
Hi guys and thanks for your kind replies
Well i wrote 30-50m but in fact i was thinking at 3-5 m !!! (i can use the wifi connection only when i'm in the room where i got my router and the connection is still weak).
I also have a optimus one and with that phone i never had such problems
The gsm and bluetooth connection seems ok. I gonna try with netstumbler and wifi analyzer anyway

When on wifi my kaiser seems to loose the signal and picks it up again.
its just going on and off.
No problem with the routersignal all wireless computers work fine.
anyone knows about this problem?

Have you put the slider to best performance rather than best battery?
Yes i did
never had the problem with the tytn and wizard.
I only get that on my TyTN II when I'm far away from the router and the signal strength is low. If you've already set the performance vs battery life slider to give maximum performance as suggested by kareem9nba and it's still behaving as reported, what happens when you're near to the router?
If it's just that your saying the range isn't as good as youve been used to with other devices, I have nothing to compare my TyTN II with as this is my first WiFi capable ppc - but I'm sure other more experienced members here will be able to comment. If you're near to the router where there's no doubt it should be working fine and still getting problems then thats a different matter.
maybe your router needs a restart or maybe its just faulty.
have you tried other devices with same router?
try a wifi sniffer/scanner see what happens (a good example would be PeekPocket)

I do! My Kaiser's performance is on a par with my old HTC Universal, which is to say, they are both terrible at getting a signal. I don't think my Kaiser is faulty as back in the Universal forums, it was often commented how useless the WiFi was in comparison to other machines. I used to have a HP Ipaq 5450 which could get a signal upto approx 20m from my router, my laptop starts struggling at around 50m. The Universal could just about get a signal upto 4m away, the Kaiser is no better.
I realise much of this is due router location and the fact that I was trying to get WiFi in my garage, but in my bedroom with a full signal on the laptop, the HTC devices struggle to get more than 1 bar and if I move 10cm further away from the router the signal goes completely.
I think the WiFi on the Universal and the Kaiser just isn't that powerful. I guess it's Maximum Performance setting is still quite low power in order to save battery life. Wonder if there is a registry tweek to increase the power to the WiFi card, and if doing that would blow the card?!

I'm using an 11 Mbps Wifi capable router (about 2003 vintage) and even with a wall and a floor between my TyTN II and the router it still works about 15 m away, I've yet to try any further as that'd be outside the house. I was impressed to see it even detected other WiFi sources in the area though. I found that even though the signal quality bar was fluctuating, my web browsing still worked OK. Bumping the slider towards the performance end did make a difference to the signal quality indicator (although it still fluctuated). If your TyTN II is only working up to 4 m from your router then I think there's a fault with either device, you should be getting better than that.
I can connect to my linksys WRT54G when beside the it and 20mt away. Even when beside it the TynII will cycle off (disconnect) and then reconnect again. I thought it was signal strength but I am beginning to think its just a crappy wifi setup on the tyn. I also have my slider on best performance.

Funny that, so am I! However I bought it because it was cheap and I really didn't know much about WiFi etc several years ago when I bought it. I notice many routers come with external antenna's, mine is all internal so I would think that it's more my router isn't that powerful, combined with the Kaiser having a less powerful WiFi set-up that older models. To be fair, the Ipaq had an external antenna (of sorts, a little lump on top) and my previous laptops didn't have built in WiFi, their external WiFi adaptors also had external antenna's.
Frankly I think that all this internalisation of components is having a negative impact on signal strength and range. To compare I have a GSM car kit with an external antenna that picks up a much better signal than a phone on it's own. Likewise my GPS can be connected to an external antenna and I've noticed when connected it will pick up more satalites, with a stronger lock, than when on it's built in antenna. It also picks up more than the Kaiser (internal antenna) or Universal (external bluetooth GPS with internal antenna) ever do.
Still, it all just about works for my needs, so I'm going to leave well alone!

i checked signal and even did hard reset on kaiser.
i still have full signal and goes to zero all the time
no clue here

But does this actually affect your browsing? In the end the signal quality bar can do whatever it wants as long as the data still gets through as far as I'm concerned and for me that’s happening. My hunch is that the reason why the signal quality bar intermittently dips down (even when nearby a router) is associated with power management on the TyTN II (which will still be in place to a certain degree even when the performance vs. battery life slider is fully at the performance end).

really i can't connect to my wifi router, while other hardware can (a laptop for example). it loops from "connecting" to "available" with 5 bars. but nevers connect or never shows an error. i tried open, WEP, WPA, WPA2 with no results... its a compatibility problem of TYTN II with some routers....
i hope that upgrading firmware, this problem dissapear....
Hi
My experience isn't that the signal itself is particlarly poor, but that it can be prone to loose connection regularly if its very weak. Atm I'm sitting some 150m from the accesspoint (quite powerfull transmitter), through a couple of concrete walls and its fast, as in almost so fast as the Kaiser can chew. Livestreaming from Youtube is np etc. The signal is no doubt very poor tho, and I have to use max signal/minimum battery on that bar you can adjust.
What drives me nuts is that it DCs me and often force me to key in the network key randomly every 1 to 20mins or so. I don't know if this is due to weak signal (both my laptop and the kaiser have 1 bar) or config of the wlan/kaiser. The PC dont DC, but its deffo a cranky connection. It almost seems like theres some auto-DC feature somewhere.
On other networks I haven't seen this. Generally I find the Kaiser wlan surprisingly powerfull, albeit it often shows a weak signal I've found this to be very relative and far from always descriptive of real life performance.

kaiser wifi low signal - wi fi poor reception - wifi disconnecting and reconnecting:
Suffered a lot with my kaiser wifi poor reception. Tested several radio versions and could solve the problem.
Radio version:
1 71 09 01 - too low WIFI reception
1.27.12.11 - disconnecting and turning OFF the WIFI with no automatic reengage of the access point or turning ON the WIFI if coverage is good.
1.65.17.56 is the versione that SOLVED my problem.
This radio was collected from the original HTC shipped rom:
RUU_Kaiser_HTC_WWE_3.28.405.0_radio_sign_25.83.40.02_1.65.17.56_Ship.exe
In this moment I am running Radio 1.65.17.56 with
ROM jjblaster3 - updated 28014 with good WIFI behaviour.
I need to underline that the reception I have now with the Kaiser, can never reach the sensibility of my Nokia 5530 WIFI or the one I have on my laptop with good antenna embeded in my LCD framem but I am happy now because the WIFI is making sense now.
Best Regards

I'm facing the same problem. WiFi worked fine and one day it was suddenly gone. Tried quite a few radios, including 1.65.17.56 and still no deal.
To elaborate, when WiFi is turned on, the icon never even comes up in the taskbar, and it continues to remain in an off state (when checked in wifi settings) even when it's turned on (in the comm manager).
I'm guessing this could be a hardware problem like a loose contact to the antenna? Anyone heard of such issues?
(On a side note, the phone function never worked either, I always got a "No Service")
I've fixed it! I believe the problem was indeed a loose antenna. I opened up my phone and removed the antenna peice (the plastic plate that also houses the speaker) and pushed up the two pins left of the camera (so that they'll have better contact with the antenna piece. Put everything back and now the WiFi works!
Now if only I can figure out why the cellular doesn't work..
I don't seem to get a very good wifi range on my hd7. The hd7 gets 1 bar where other devices in the same position relative to the router get 2 or3 bars, anyone else find this or is mine a faulty device?
im sorry i just found this but i have the same problem! i cant be more than 1 wall away from my router or my hd7 won't find my wifi! i hope this isnt a hardware issue:/
As for Me the Hd 7 has had the best connectivity for wifi for me .. totally pleased, might be somthing to do with the routers.. I have bad connectivity with my Hero but brilliant with the HD 7
WiFi issues
I have issues connecting to WiFi even in the same room as router is, on open networks in coffe shops and hotels.
It's very weird, I get the message that the password is incorrect, or the network unreachable.
I actually dont recall that have one case of successed WiFi connection, I think this is very strange!
Any advices how to improve phone's sensibility, where is Antenna placed?
thanks in advance,
silversurfer03
I have been having the same problem. I noticed turning off my data connection completely actually helped some. It seem like the HD7 will try to connect through whatever connection is strongest.
can anyone test different Radios, see which one get better wifi reception.
I tested mine just next to my laptop, while my laptop reach last 2 bars, my HD7 disconnected sometimes.
Wifi reception.
I get pretty good WiFi reception I had to find a specific channel in a congested area i.e. my house but that was router side. I use my phone on WiFi at my house upstairs through a few walls with little issue. It gets the same level if reception as my iPad. Not really a great example there. While alot can effect WiFi reception you guys may have a legit hardware issue.
Same issue here. My HD2 could connect to my router anywhere in my house - however I move to another room now and the HD7 has real problems as the signal is showing as weak! I know it's not weak as my netbook and old HD2 still have no problems at all.. let's hope a radio update will sort it pout.
same issue here
I also encounter big problems with wifi.
At my place I can connect with my laptop and any previous phone I owned to my wifi from my bedroom, but not with my HTC HD7. When I'm in the same room I have nog issues at all.
At my parents place my phone doesn't like the wifi, I am not able to connect to the wifi even in the same room. Other phones are not having issues with the wifi.
Same issue on my EVO, i only have a 20 ft range on my wifi now. Not sure what happened but it really bums me out not being able to fix it.
I am also having this same problem with my EVO. Started not long ago and I have no idea why or how to fix it. no wifi really sucks
I have the exact same problem ever since I bought my HTC HD7S.
WiFi range is horrible regardless of the OS I'm on.
I just updated it to 7.8 and it is exactly the same.
I sent it in to HTC and they said they'd charge me 160 USD to fix it, the phone only cost 99 USD no contract, no fees, but carrier locked of course so it's not worth it.
I did drop it on the floor in Oakland, would any of you with this issue have done the same?
Would that be why my WiFi is so horrible?
What could I do to fix this, replace the WiFi chip inside the phone?
Hello
I bought the P880 about two weeks ago.
Unfortunately I notice a WiFi issue ; I don't know if this is affecting only my phone or if all p880 have this issue.
At low WiFi signal the download speed is very low compared with other LG phones.
Strange is that the upload speed is always better in the above conditions.
This issue is present only at low WiFi signal on good signal there is no problem.
I don't know if is a HW problem or a SW problem.
Maybe the WiFi chip is not as sensitive as the chips from previous LG phones.
Also is possible to be a SW issue (maybe is something wrong in the WiFi RF calibration)
Or maybe my phone has a fault.
Below is link from a video where I compared WiFi speeds between LGE730/LGP990black/LGP940/LGP880/LGP990white connected to the same network in poor signal conditions.

My phone works quite ok under poor Wi-Fi signal coverage, so I am pretty sure that ur phone has some problems, which ROM are u using?try to flash the ROM again, if you still having this issue, i would recommend you to send ur phone back to LG for repairing.
Go to wifi settings, en press the menu button click advanced and uncheck the box wich says: Avoid poor connections.

I have the same issue. At the same place my previous Huawei Ideos X5 got stable connection although poor, but this Optimus 4x gets on and off connection.
This poor wifi connectivity is very annoying.
Unfortunately I do not have the possibility to exchange the phone because I don't have waranty.
Now after some good weeks spend with the P880 I also noticed the latency over wifi is high.
For example the ping on other phone was 12ms and on the P880 is always greater then 180ms.
I hope the optimus G will be released soon in Europe and hopefully then I will get rid of this wifi problem
I'm now with a ping of almost 1900ms, but I'm in a shopping centre almost without signal At home generally is around 12ms.

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
I'm curious how your wifi is performing because i'm getting pretty bad wifi reception and starting to think it's maybe a hardware fault.
On my old phone (One X) i'm getting full bars and a link speed of 72Mbps allmost everywhere in my livingroom.
On the One mini i have never had 72Mbps (max 54 and mostly 26 or lower) and frequently loose wifi connection in my house where the One X easally maintains a strong connection.
The same is with the bleutooth connection. When streaming music I only have to touch the top of the right corner and things start to stutter.
What is your experience? Please let me know so I know if i have to send it for repair.
