i'm like just like 12~15meters from the source but all i get is a tiny dot in the signal, is there an app that can boost the signal of the HD2?
i think I won't try to go the HardwareMod way if there are any
tnx

wifi is a two way system, you need both the router and the device to have higher power. If one is lower than the other it can only go at the speed of the slower device interfearence will also have an effect, Bluetooth devices, microwaves, power lines, wireless video cameras, hell, most of the wireless gear you can buy uses similar frequencies sooo. However, the big question is why you dont get a reasonable signal 14 meters away, soo, whats between you an the router?
in answer to your question, no, however the HD2 does support 802.11N which on paper should have a stronger signal, if your router supports N then enable it on your device and router and see if thats better, but my money is still on something stuck in the middle thats screwing with the signal
edit, uping the wattage is unlikey to be possible, and would generate significant heat and draw more power,as well as poentially being illegal, hardware mods may be possible but unless you can check out the radio ROM i doubt you'll be able to see whats possible, if anything, in a software sense.
Some hd2s have a hardware defect where all the wifi signals are lower than normal
Really depends what's in those 12 to 15 metres! At home, I struggle being ~2 metres away from my router, but there are 2 walls and the stairs in between. You could try moving your router or setting up another access point.
my wifi worked perfect for two weeks, then the signal got weak, stumped.
thanks for your inputs guys, yes there are walls in our office & i guess our MIS has really limited the transmitting power just in the display room coz even when i'm at the door of that room I only get two bar.
HI. I had this WiFi problem since I bought the phone like 6-7 months ago.
My previous phone was a Nexus 4. It had good wifi reception. From my apartment I could find like 6-7 routers with +2 signal bars.
My Lg G2 sees only 3 routers, mine and 2 others that are at 1 signal bar or sometimes no signal. I tried to flash other basebands but no improvment. I tried flashing other ROMs.
I now tried to lift the little conectors on the back cover and put a little piece of paper under so i'm sure they connect (i don't know if that's how wifi works because it's working the same with or without the back cover).
What else should I try? Is there something to do or every G2 has signal problems?
I might have a solution for you...

I had a similar problem with my G2. The old phone (Optimus 3D) had good and strong wifi signal. With this one, from the first day to connect to home network, I had connection problems and all I had to do was to set to one network mode (and only one - I use G), on a single channel (give it a low one - 1 to 6) and a 20 Mhz band channel. And guess what: I can have a clear and strong enough (plus stable) from down the street, while my flat is at the third floor.
Please try to modify your modem/router settings as stated before and let me know the results.

My router works fine. I have it on G/N 20Mhz Channel 5. I work installing internet antennas on top of buildings so I would like to access the routers from far away.
Another question. What's the purpose of the gold connectors on the back cover?I have like 3-4 pairs. My wifi, network and gps work with or without the cover. No difference.

You must have only one type of connection. Or at least in my case is so. I have only G, not mixed one. As for back cover connectors...I have none. Stock back cover, gold edition of D802.

My brother sees 8 wifi routers with 3+ signal bars with an old Sony xperia tipo. I see only 3
Hi,
My ZUK Z1 european version has just arrived and I am noticing that it cannot take the 5Hz wifi when there is some distance in between. If it does it, it disconnects in seconds. It does connect to the 2.4Hz g without too many problems (some times even not this one). If I put only 5Hz networks, the same happens. Sometimes it doesn't see the signal at all.
This doesn't happen when I am next to the router. So, since the 5Hz deteriorates more with distance (AFAIK) what I'm describing shouldn't be surprising. My doubts are because with the nexus 4 (Android, not cyanogen) it grabs the 5Hz without any problem at exactly the same long distance (2 thin walls, few furniture in between), and I find very unlikely that the wifi chip of the nexus 4 is superior than the one of the zuk z1.
UPDATE:
It is very strange. With the ZUK, in front of the router I get 110 Mbps (5Hz, n-only), when I move to the room in question I get 3-4 Mbps only, so about to be disconnected.
With the nexus 4 (same 5Hz connection obviously), I get 50 Mbps when I am in front of the router AND when I am in the problematic room. How is that possible?
If I test connecting to the 2.4Hz (b,g,n), the nexus 4 gives the same 40-50 Mbps no matter the distance. I have to go to a very "protected" room to see a drop to ~15 Mbps, again showing no difference between the two bands.
If I test with the zuk, it gives 20 Mbps, if I move to the very "protected" room, I see a drop down to 0.3 Mbps
So, it is like the wifi is much better if you're in front of the router, otherwise is significantly worse? Is that feasible? Can it be a software problem?
Hello! first of all excuse my bad english
I received today me ZUK 1 and im having the same trouble, its impossible to use wifi without problems when you are in a different room from router, and especially when you put the smartphone in horizontal position ,grab it with two hands and cover the superior part with your hand, when i do this i simply lost the connection even if im in front of router. I come from HTCmania, a spanish forum of smartphone and we are few people with the same problem and is very frustating that there is no solution and noboy in Lenovo or ZUK says nothing about this trouble.
Me too. Wifi is very very very bad if you hand is in the top (camera zone). Horizontal, vertical, it does not matter if you cover the area with his hand, zasss wifi dies.
Sorry my very bad english.
Same problem here
I have the same problem as described. I have not noticed if my hand position affects it. My OnePlus one and my Sony Xperia Z1 compact both manage to hold on to the wifi in my bedroom albeit less than full signal. The Zuk z1 just keeps dropping off and sometimes doesn't find the wifi.
Have anyone contacted Zuk about this? Mine was bought through Spanish eBay but seems to have been sent to Spain from Germany.
Following the thread for a solution as this problem is a definite dealbreaker.
Daniel
Uau, I've just tested it and while it is unrelated to the problem that I say (this is, the ZUK receives the 5Hz band very bad it seems) it is completely true. While doing a wifi test (Wi-Fi Deadspot app), connected to the 2.4Hz, from 55 Mbps if I put the hand over the top part of the mobile it drops to 30, if I put the hand in the middle part of the back zone it drops to <5Mbps!!
*Having it over a table doesn't make a difference for me.
UPDATE: The measurements from this app seem very variable, based on other comments it doesn't seem to be related to the software but to the ZUK. Now the 5Hz band gives excellent results from the room where before it couldn't even see the wifi.
So it does seem capable, but VERY unstable I guess. Is this hope for waiting a software-based solution? Or we should mark this phone as a wifi-less phone ...
(damn ~_~ they sure knew about this from the units sold in China)

2,4 ghz
Just checked and it turns out that my wifi is on 2,4 ghz. So I guess the conclusion is that the problem is unrelated to the frequency.
There are two problems:
Problem 1- Wifi drops when your hand is on the top of your phone, irrespective of the frequency
Problem 2- Wifi in the 5Hz is very unstable and/or much worse when compared with a nexus 4 phone (relevant provided it is an old phone), related to the frequency (or it seems so at least)

I didn't noticed anything before i read this and tried to put my hand on the upper part of the phone : my WiFi connection instantly shut down even if I had 3bars over 4... So yeah there's a real issue with the WiFi antenna here :S (first real drawback I have with this device...)
Apart from that, I owned a Nexus 4 too just before this device and I personally have a better WiFi reception on my Zuk Z1 (one more bar for both 2.4 and 5Ghz bands)
Does the same happen with ZUI os?
I also have a Wifi problem with the international version of Zuk Z1.
Testing the Wifi with the App "Wifi DeadSpot" in both the Zuk and a Oneplus 1, the results are:
2m far from the router:
OnePlus1: 38Mbps (GOOD)
Zuk Z1: 9Mbps (AVERAGE)
10m far from the router:
OnePlus1: 22Mbps (GOOD)
Zuk Z1: 0.45Mbps (POOR)
In both cases the phone is in vertical and without touching it (holding it near the camera apparently really makes Wifi coverage worst)
If the Zuk is in horizontal position, the Wifi signals is also worst: 0,5-1 Mbps at a 2m distance.
I tried resetting the Zuk to factory settings and the results are the same, so I don't think it's a software issue. Could be a manufacturing defect or just a cheap wifi chip?
Wifi on the ZUK Z1 is better than Note 4, S6, Xperia Z3+ and Mi Note.
On some positions I don't get Wifi, with the Z1 2/4.
Speed up to 50Mbit/s over 2.4GHz. With 5GHz about 120 Mbit/s. I don't need more.
Hello, I received my EU Z1 today and I'm coming from a Nexus 4 too. I don't have any trouble with 2.4ghz WIFI, the connection its perfect two stories under the router and I can say its as good if not better then the Nexus 4 holding it in any way. I think you got defective devices.
I hope your are right.
I'm considering buying this device. Would be great if other people could tell about their wifi reception.
Same problems here, with cyanogenos, didn´t test ZUI os.
I´ll posted the bugs on cyngn forum here: http://community.cyngn.com/t/some-m...lash-flashlight-poor-wifi-back-button-led/208
But not sure if its a software or hardware issue, i guess hw.
It's pretty random...
If i have the phone 3-4m from 2.4ghz router through a wall:
Keeping the Z1 in the same position, without touching it, WiFi reception varies from 2-4Mbps to 40Mbps (from test to test in Wi-Fi deadspot app). Can't predict when I get which speed. Mostly it's very low, though.
Disconnecting and reconnecting sometimes helps but mostly it doesn't. My old Huawei Y300 has a solid ~18Mbps when tested at the same spot.
Then again also the phone reception randomly drops from 3 bars to 1 to just go back up to 3 all within 1-2 seconds. (which might be unrelated but coincided with having higher Wi-Fi speeds)
Here's hoping for a software bug....
Cheers.

There is one thing that is rather consistent though:
Whenever the display turns off during the Deadspot test, WiFi drops e.g. from 40Mbps to ~8Mbps. I first observed it by chance and then switched off the display on purpose several times while the app was running...
In the WiFi settings it's set to always keep on, so that shouldn't be the issue...
@tuatara42
I think i noticed sth similar, i had map downloads for navigation, around 2gb of data, it was half done in a few minutes but when it gone into standby mode and i woke it up 10 minutes later it barely progressed, so that means the wifi must have been slower.
That gets me a bit of hope that it´s "just a software problem".
I just tested the speed right next to the router:
Same speed, no improvement, 1-4Mbps.
Full speed with the Y300.
Actually I'm pretty sure WiFi was much better in the beginning, before the latest COS updates...
COS could be part of the problem, with CynaogenMod on my old phone I have the same problem with wifi speeds when the screen is off.
I just did a rough test using Wi-Fi Deadspot. At about 7.5m, through four very solid brick walls, from my 2.4 Ghz router I got 32.49 Mbps with my Z1, and 27.74 Mbps with my old N4. So WiFi is fine for me.
Which COS12.1 version are you on?
Hello all,
i'm sure i'm not the first to ask, yet i didn't find any threads about this.
my phone can't seem to connect to 5ghz wifi when the channel is a higher one (149-161). it doesn't even see the SSID. when I switch to the lower channels (36-48) I can see it and connect.
I would much rather fix this so i could use the higher channels where the signal is better overall.
any idea why this is hapenning? on my iphone 6 it works great when using channel 149.
I'm running 5.1.1 Fusion Rom rooted.
cheers!
Anybody knows ?
maybe it's a hardware problem?
i'm seeing this same behavior on SM-G900T (TMO S5) and other devices apparently due to missing country code and calibration files.
please see notes and upvote BUGBASH-2594 : 5ghz WiFi bands partially not seen as client and not available at all as hotspot
hopefully that helps bring together awareness of this widespread issue that seems to be easily overlooked (i mostly find myself using 2.4ghz networks anyway).
I was wondering if anyone here is familiar with the Note 4 antenna hardware... Recently my Note 4 fails to connect to 3g / LTE networks though it connects and works absolutely fine with basic 2g networks. I ruled out everything I could software wise and also ruled out a sim card error leaving just a hardware fault to blame...
By chance this morning I just happened to be about 700m away from a cell phone mast so re-enabled 3g / LTE in network mode and to my amazement it connected to 4g and 3g with full signal strength and worked fine. Testing it again just 1.5km away resulted in the same issue... no 3g or LTE just 2g. This all leads me to believe that this is likely an antenna issue?
I replaced the motherboard in this phone (EMMC error) a long time ago and the charging / mic / button block at the same time as it could be a bit unreliable... the phone has been faultless since (until this much more recent issue with signal).
I know my way around the inside of the phone reasonably well but I can't seem to find out whether the antenna is purely made up of just the charging block, the blue & white wires connecting this block to the motherboard or a combination of both?... does anyone know the answer to this?
Both wire connectors and charging blocks are fairly easy and cheap to source and replace so doing both seems to be the route I'm heading down at the moment but I'm curious if it could possibly be only one part that is at fault (given that the antenna must be working to some extent to connect to 2g networks) ?
Anyone have any ideas?

Thanks for your reply the parts are in order but won't be here for a few more days yet... I'll let you know the outcome...
Just to conclude this thread I first replaced the antenna wires then later the antenna / charging port block neither solved the issue and so it would seem it's a fault with hardware on the motherboard. Probably an isolated case as I've yet to come across another mention of such an issue.

I just started having this issue after the first of January. I was told it was because the 3G was disconnected by the cell provider and that the Note 4 defaults to the 3G antenna. So my question is if anyone knows if there are two antennas in the Note 4 and if one is specifically for 4G? Or if there is a software update that can resolve the issue?
