Slow WiFi connection

I have noticed that my G2's WiFi connection runs VERY slow. I get speeds of 2mb/s while on a computer I get 25+mb/s. I get the same ping on both devices. Is this a hardware or software limitation that can be solved by a kernel fix?

There is a thread about the G2/DZ having WiFi antenna issues. This happens when you use the phone in landscape mode. Signal bars drop significantly. In my case, I got totally disconnected (but I had poor WiFi signal strength that time). However, when I remove my hand from the top part of the device, signal strength and speed return. This could probably be your issue, since I really get good speed from my DZ. I could even stream movies over WiFi.

Do you have wifi calling enabled? Try disabling it and restarting. You'll likely see regular speeds again. Works for me every time.

Nope, I will be looking at the bcm4329 source when I get my computer running to see if I can boost the speed a little.
This may also be a router combatibility problem. So we can narrow it down can people post this:
Router brand/model
Wireless B/G/N
Wpa wep or no security
Hidden access point (yes/no)
And if you are having problems

Wireless B/G/N: Wireless N
Wpa wep or no security: WPA
Hidden access point (yes/no): no
And if you are having problems: Only when wifi calling is enabled. Must disable that and restart in order to get expected speeds. For example, it drops from standard 12mbit to like 1mbit.

I have the same problem with my G2.
Wi-Fi is on all the time when I'm at home, as is Wi-Fi calling because the signal is very weak here. When I first connect to Wi-Fi it's very fast. Normally I get approximately 17mbps down, 3.5mbps up. However, it seems like the connection "goes stale" after a while and I end up only getting about 2-3mbps both up and down.
It's not consistent though. Sometimes it gets slow right away, other times it will take a couple hours. But it always drops to the 2-3mbps range consistently. Plus I always have issues with the connection after it drops in speed: No connection errors, sometimes unresponsive, etc.
To fix it I simply turn Wi-Fi off and back on, but that gets to be a hassle because I have to do it every time I want to use my phone.
It has nothing to do with holding the phone in vertical or horizontal orientation, or signal strength, because even when I'm using the phone right next to the router it still happens. I never had this issue with my Cliq, but it didn't have Wi-Fi calling, which I'm thinking is the cause. Though I haven't tested it to see if it still happens with Wi-Fi calling off.
It happens with any ROM, though currently running CM7 Nightly 27.
Anyone have an explanation, or a solution?

Update: After testing it seems to only happen when wifi calling is enabled. Although I have to turn wifi off and back on to fix it. Simply turning off wifi calling doesn't fix it.

HTC One X WiFi problems solved!

Ok guys so I've been complaining about my WiFi speed and loading time of the phone so far. I have a new router and I've even tried sitting right next to it! But still the same thing!
I'm sure that I'm not the only person who feels that the phone is slightly slow on WiFi out of the box with standard settings.
I have actually solved the problem and It's a very EASY fix! Do the following:
1. Settings>WiFi>Advanced >Tick best WiFi performance.
I did this and honestly is like a new phone! I am so much more happy with the phone. The difference is night & day!
I hope this helps people start loving their One X again!

What about battery consumption with this seting on though?
That was always my biggest concern for not using this setting.

Router Settings
Hi there,
when I got my HOX out of the box at home and connected it vie WiFi to my WLAN Router Fritzbox 7570 vDSL the HOX connected, but it was not possible to bring up a website like www.google.com, and after very little time the whole WiFi network collapsed, with all other clients showing only restricted connection, but no access to the internet anymore....restarting of the router was necessary.
In a German forum someone suggested to switch the WLAN from 2.4Ghz b+g+n to 2.4Ghz b+g which is a setting option with my particular Fritzbox.
I did so, and voila....no problems whatsoever anymore... HOX showing 54Mbits as does my Samsung Gtab 10.1n or my laptop...
just checked when the router is set to WLAN 2.4Ghz b+g+n the HOX shows 11Mbits and the laptop 130Mbits...
Maybe it is a good idea to see if you have a setting on your router to disable the n standard and only run b+g...and report back.
Then you don't need the Best WiFi setting at all...at least I don't need it!

I am quite sure the battery will get a hit. No free lunches.
I do notice when the signal is weak my wifi seems to disconnet and reconnect.
I have just noticed there is another option that says switch network when the wifi signal is weak. I have loads of wifi signals around my area. Maybe it was trying to connect to my neighbours. I have unticked it now (default is ticked!) and see if that issue still comes up.
But the disconnect/reconnect was pretty fast. Nontheless it is still annoying.

Well some people may have devices at home that run at N. Switching the router off to G-only may not be desirable. But as I said above, try unticking the auto switching option. It could be the phone was trying to switch band when it detected the current signal was weak.

Im sure most of us had already tried this. I'm still unable to connect to most networks or my connection gets cut off every 20 minutes or so. HTC rep explained that there must be an issue with the networkS I'm trying to connect to, as he is able to exclude a bardware failure ias a possible cause by virtue of the fact that I'm not entirely unable to connect to a network. He went on to say that you may compare this to a Turbo on a car, it is either broken or in complete working order. I was stunned at his incompetence in both mechanical and electrical engineering.
Bottom line is, it's impossible to get a proper connection on my phone.

For everyone's reference, I am using TP-Link 1043 router on b+g+n mode and my One X is working fine. No need to turn on "Best Wifi Performance" or turn off "Auto Disconnect".
Sent from my HTC One X using XDA

Ok so I will post my battery usage after today of having best WiFi performance on. Seems like it may use an extra 1-2% so far. Will know for sure ay the end of the day.
One thing I can notice is that when I look at the battery stats the WiFi usage bar is solid blue now. Or used to have multiple broken lines through it.

WiFi Problem
I had same problem on my HOX.
I just changed the DNS settings in router's configuration. everything's working now.

OK so I hosted my macbook as a hotspot.. my every other htc except oneX can see and connect to the hotspot...
Strange thing is the oneX can see the wifi networks from surroundings!!
any suggestions?

Hi
Have been pulling my hair since day one with this problem and thanks to this thread i must say i'm a bit relieved to see that i'm not alone. Have changed everything in my WiFi settings now and the only thing that have improved it somewhat was when i changed the encryption to just wep.
Now my hopes are with the new upcoming 1.29.

Got same problem
- Changing encryption to WEP (or even none) works
- Changing band (2.4Ghz to 5Ghz) does not work, even when forced to connect to either
It's terrible, I would love a good solution. I will try all three solutions, one at a time:
- Best WiFi
- Auto disconnect
- Remove N-band from router (but why oh why should we do that!!)

hox didn't support ad-hoc wireless, need to be on AP mode, try download some software such as connectify to share internet, not sure what is on mac though.

Hey guys I've noticed something lately with the WiFi.
If you open an app like tunein radio and browse the web, the WiFi works much better? Seems that the WiFi works better the more the processor is made to work. Anyone else find this?

btw: The only things that work are:
- have only B and G and to disable N on the router.
- use only WEB as security

5GHz WiFi not working, well sorta....

Wondering if anyone else is having issues connecting to a 5ghz network? I wasn't able to get it working, wouldn't even show up in available networks. That was stock out of the box, and after flashing a couple ROMs. I'm using slimbean now and am able to connect, but I have to turn WiFi on/off several times on the n7 before it shows up and connects. My s 3 connects no problem.
And I've tried all the standard troubleshooting on the router. Even changed some settings on the 5GHz band.
So if someone could double check for me that would be great!

5ghz works great for me. Reception is the best I've ever gotten on that band. Currently on stock, but it's worked in CM10 too

The 5 ghz didn't show up for me either. Had to manually enter the SSID and it connected right away.
Sent from my Nexus 7 using xda premium

On the first boot it didn't show my 5GHz WiFi, but after I connected it to my 2.4GHz, it immediately downloaded an update and rebooted itself. When it came back up, it saw my 5GHz.

My Nexus 7 connects to my 5ghz router band all the time. I think it actually prefers it. I'm using it right now.
Sent from my Nexus 7 using xda premium

Well I think I have it working. I gave the n7 a static address and now after a half dozen reboots its auto connecting every time. I tried changing channels on the router. Tried 20/40 MHz channel width. Ticked on/off all the options on n7 WiFi settings. Nothing worked. Then I set static address on my tablet and router and like I said so far so good.
I'll update if there are any other issues because doing a search showed a lot of other devices having this issue. But none of the results recommended setting a static address. Maybe I got lucky. I could use my 2.4GHz network reliably but I want full network speed since I only have the 16 GB model and do a lot of folder syncs to keep my SD storage free.
Edit: scratch that. Worked half dozen times in a row. Rebooted after I wrote this and it didn't connect.

During initial setup i was not able to connect to my 5ghz but i was able to connect to my 2.4ghz. After setup was complete i was able to go in and switch it manually to the 5ghz network. If i power the device off and turn it back on it would not connect to my 5ghz or my 2.4ghz. I then went into wifi advanced settings and switched to 5ghz only and it connected immediately to the network and hasn't lost it since. This was true before and after the update, i am stock, unlocked and rooted. I also do not broadcast my ssid.

If I am connected to 5ghz and go in advanced and select 5ghz only, it disconnects me from WiFi. It will still show my 5ghz network in range with good signal but if I now try to connect..it does nothing. Keep clicking connect and nothing happens. Then go back and put frequency on auto and the 5ghz disappears. I then have to toggle WiFi 4-6 times before it connects again to the 5ghz.
Strange.
Sent from my Nexus 7 using Tapatalk 4

I had the same problem at first too. Here's what solved it for me: set 5ghz frequency to 20mhz instead of auto, change the channel from auto to any number you want, 5ghz will most likely be completely clear in your area so just choose any channel. After doing that it should see the 5ghz network every time and connect automatically.

I'm not sure. Seems like software to me because once its connected it stays connected. And the signal range is really good. Better WiFi than any phone I've ever had. Better than my laptop too. My s3 has no problems connecting. Even with all the router settings I've tweaked its never had an issue connecting with the s3.
Are you able to connect?

In another thread someone noticed his WiFi settings were set to Europe. He said he hadn't changed them and that he was fresh on stock (his first time booted). Double check your settings if you're still having issues.
Settings | WiFi | advanced | WiFi region code.
Mine was also set to Europe as well for some reason. If your router is setup to use a channel not available in Europe this would cause the problems described here.

OK guys, I think I have as real solid lead on this bug. I'll update with some info a little later, I want to test this some more. But for now I'll say that I made some changes and I have had zero disconnects or problems connecting while toggling or after reboot. And I mean 100% connection rate after 50 toggles and a dozen reboots.
Till I can get the info up, one question for you guys having the same issue. Do you have multiple routers in your network and/or custom firmware on your router?

[Q] Poor wifi signal

Sooo I've had my M8 for nearly a month now and I love the thing. However, I notice that I've been having some issues with the M8 not being able to detect or connect to my home and office's wifi. My laptop and my fiance's Nexus 5 can detect our home wifi network with full strength.
Interestingly, the closer I get to my router, the stronger the signal gets, but the moment I move maybe 20 feet away into another room, the wifi cuts out or gets very weak. I understand that distance is a factor, but I feel that my M8 should be able to connect to my router in the next room, especially when other devices can do so with no problem.
I think it's also worth noting that this was not always an issue. This only started happening recently - the only software upgrade that I did was the Verizon push that installed right out the box. I have not made any changes to my wifi network at home or work.
I've tried a couple of things with no resolution, including;
Resetting my router (power cycling)
Restarting my phone
Forgetting both wifi networks and manually re-adding them
Changing my wifi direct name
Turning on airplane mode, turning off my wifi, turning off airplane mode then turning on wifi (this was a suggested method for the M7 that I saw on another forum)
I did some Googling and didnt find much, so maybe I just have a lemon, but I did see that wifi connectivity was an issue with the M7.
Any ideas or suggestions would be greatly appreciated!

I'm having the exact same problem getting over 20Mbps over Ethernet but then 0.25Mbps on my M8 over WiFi even when close to router

Have you guys played around with your routers settings?
What signal is your router on, wireless b,g,n,ac?
Is it throwing mixed frequency? (2.4ghz or 5ghz or both)
Go to WiFi settings in the phone, then advanced, then it will probably say "auto".
Try setting it on only 2.4ghz or only 5ghz see if that helps.

LG g3 WiFi issues

Is anyone else having this problem? My phone keeps dropping the WiFi signal even if I'm next to the WiFi router. The WiFi indicater shows good signal with all bars lit at all times and I don't get any notifications of signal being low but it still doesn't load/connect to anything. It's very sporadic, but regular.. once singal is lost it won't load anything for a minute or 2 even if the WiFi on the phone is turned off and on. I've tried resetting the router but the problem still persists. All other devices connected to the same WiFi don't have any problems. I'm using the virgin super hub by netgear.

I have a similar issue at my partner's house. When I first got the phone I had no issues connecting to the 5 Ghz wi-fi connection, but lately I have issues with the 5Ghz, but connecting to his 2.4 Ghz connection works well. His device and other household devices work well on the 5 Ghz connection. It is annoying, but since the 2.4 Ghz seems quick, I am not going to worry too much about it right now. Hope there is a solution though.

I remember my z1 having similar problems...it was fixed by changing the security mode I think...wep..wpk...or something...just fool around with it...no harm in trying

I have a NetGear accesspoint that the G3 refuses to connect to regardless of the G or A bands. So frustrating.

Stard having this issue this weekend, thought it was the router location and I repositioned and still no help.
Hoping and update fixes it

I too have experienced issues with WiFi during my last 4 days of ownership. Perfect WiFi signal (I was sitting within feet of the router) yet no Internet connection. Cycling WiFi off and on fixed the issue. This occurred on two different networks using different hardware. Both were using WPA2-PSK authentication. No other devices on the network experienced any issues.

That option was already enabled on my device. I never enabled it, so it must have been on by default.
Also, when this happened, my G3 still had a valid IP address

Have same problem since day 1. Cycling between 5Ghz and 2.4Ghz and vice versa seems to fix for the short term.
But seems to happen on a daily basis.....!

I have the issue has well. In fact, mine will sit at obtaining IP address.

i have same isuee
i have same isuue here with my lg g3 16 gigs model
wifi sigal drops all the time i did factory seetings and did not help
plzzzz help as am start to hate my device

add static ip address to resolve the issue
I added static ip address and it was able to connect to the wifi but it will
be the same problem when you connect to another wifi at a different location.
Do not change network prefix length/DNS1/DNS2. Keep these the same.
You could use this as temporary fix at home atleast and connect to wifi.

Disconnect completely from your WiFi, switch off WiFi on the phone, turn back on and go to advanced settings, uncheck the Google auto scan thing, then connect back to your WiFi.

Still have same problem

It worked on mine. Much more stable.

I am also experiencing this and it is really annoying. Toggling WiFi off and back on always fixes it, but that is not an actual solution because the problem happens so frequently.
I have tried:
Disabling Sprint connection optimizer
'Keep WiFi on when screen is off' is enabled
'Allow WiFi scanning' is disabled
'WiFi signal weak' is disabled (set so that it does not disconnect from WiFi when signal is weak)
'Battery saving for WiFi' is disabled
Using a static IP address
Factory Reset
Forget network
I still have had no luck. Does anybody else have any suggestions? I have about a dozen devices on my network and they play nicely; this is the only device giving me trouble. I am starting to wonder if it is time to RMA?
EDIT: It doesn't seem to happen when I connect to the WiFi at my work. Hopefully flashing a newer build of DD-WRT will remedy this. I love this phone except for that one issue; unfortunately though, this issue would be pretty hard to live with....

Same thing here. Before G3 I had G2 and Flex, both had the same wifi problem. Funny thing is that some $150 Chinese almost noname generic phones never have this problem on my home wifi. It's exclusive to LG.

Same Problem here. I am having a Nexus 5 sitting next to it. No problem with the N5 but constantly interruptions with the G3. This phone is starting to annoy the hell out of me.

I have the VZW G3 rooted, have no issues with WiFi on either antenna using an Asus dual band router.
I did have issues with a dlink, but it had issues with all phones not just the g3 so I replaced it.
