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.

Anyone else having WiFi issues?

I'm having issues with WiFi staying connected in my house.
Anyone have an idea on what I can do?

Just tossing this out there...
Alot of wireless routers provided by cable companies are limited to 5 devices... my provider actually has 5 listed in their tos..

And that would make sense, but it's also when I'm on my work's WiFi

What firmware?
Mine works fine. I use wifi sync with winamp and did my initial sync overnight without any errors.

2.3.3 Stock, no root

I've been having wifi issues too. It's connected, but there is no data being sent/received. It's happened on sense, cm7, omfgb. I've tried reseting the phone and the router but nothing has helped. Has anyone found out how to remedy this issue?

I'd love to investigate further but I can't reproduce this problem
Can you describe your wifi setup (router and phone) so I can try to replicate the conditions?

I have an old linksys srx200 router connected to the router Comcast gave me (the black box that runs phone and internet). My phone is a recently gb s-off rooted inc2. I tried sense (stock and virtuous), omfgb, cm7 and they all have the problem so I'm thinking its either my phone or router...
A few posts above talks about having too many computers connected to the router being the problem, which could possibly be my case but hasn't been a problem until a few days ago... I have up to 2 desktops and 2-4 laptops connected at once (yes, I have a big family). I hope all this info helps
Sent from my ADR6350 using XDA App

My first step would be to update the firmware on your router. You also states that your linksys srx200 is connected to a Comcast "router" . Do you mean modem or is it a gateway (modem with built in router ) because if the latter, then the dual Nat setup may be causing issues. But with some info we can tackle it.

It's a Comcast modem that also hooks up the home phone line, sorry about the confusion. I have updated the firmware, but linksys has only come out with one firmware update in the years that I have had the router. The update hasn't helped much and the open firmwares like ddrt (if I remember correctly) isn't supported for the modem.

I have problems with wifi dropping out in my house, too.
Comcast modem, old D-link 524 router, all other electronics have no problems staying connected, down to my old Palm TX.
On the Dinc2, it drops frequently.

I was just noticing this last night.
I'm staying in a hotel and in my room I get 60% signal with my laptop, however on my phone it shows 10% signal and intermittently drops out
anyone else having issues with poor wifi signal?

Never had a problem with intermittent WiFi, would update your firmware.

I seem to be cutting out on wifi calls

A couple friends have complained I cut out while on wifi calling. I don't notice them dropping. Any ideas?
I'm on Darkside 2.5.1, my network hardware is...connected to Linksys E3000 operating as an AP, upstream is a Linksys E4200, Cox is my ISP 25 Meg circuit. Ping times over the same wifi connection are always under 35ms.

I had that happen when I would walk to far away from the Router...is this happening when your standing close to it? Seems odd for sure.
Kinda off topic but have u noticed voice lag when using wifi calling?
I have stopped using wifi calling as the voice lag is disturbing compared to using the cell network which has no voice lag issues.. Makes zero sense to me.

I havent noticed any lag, just apparently cutting out. Im not far away from my router either...full signal. Im going to try an experiment and connect to the main router upstairs instead of my AP downstairs...maybe something in that connection is causing it.

I've had problems when using a bluetooth headset while on wifi calling. This happens on stock and on both roms I've tried. I don't have trouble with wifi calling as long as I stay off of the headset.

I've experienced the same issue but always blamed it on my Internet connection.
Sent from my SGH-T989 using Tapatalk

Its not the internet connection, for some reason the current ROMS dont play well with wifi sharing, or should I say Wifi and Data connection. I was running Juggernaut5.0 when I noticed that the wifi would stop working after 15mins. I also used All Share and it at the same time wifi calling would stop working. I also noticed when I woke the phone from sleep state, the 4g symbol would return and then I would loose wifi calling. The 4g would disappear and only wifi would show but calling still wouldnt connect. I returned to my nandroid of the stock rooted and I havent had an issue since. Wifi calling will always work along with allshare. One thing that I did notice is that airplane mode would help keep the consistency across the board. IDK
P.S. my gateway is in my bedroom where I mainly use my phone. Most of the time its in arms reach, sits right next to my xbox

Well I set my phone to connect to my main router upstairs instead of the AP downstairs. It seems to have helped a bit. Friends reported far less cut outs. Only a couple in a 20 min call.
Perhaps there are others with similar set up having similar issues this may help.

[POLL]Does you Wifi work without any gimmicks?

Kindly poll whether you can use wifi properly or with any fixing methods such as copying folders from 4.1.1 roms, or Disabling Wifi Power Save Mode.
If you use any other method apart from the two mentioned above,kindly comment about the method.
Lastly, if you are able to use wifi Without Any Fix, do post your firmware and rom.
I am currently on DMC3, wifi worked properly for a day without doing anything and then it just broke. Network disabled due to poor connection. And then i had to use the copying wifi folder from 4.1.1 trick. And it works fine now.
Kindly download https://play.google.com/store/apps/details?id=de.android.telnet&hl=en
Go to wifi tab and post the frequency you see.

I never experienced issues with Wi-Fi on my Note 2 on 4.1.1 or 4.1.2 stock.Whenever I reach home a message appears:Connected to .....

No issue.
Used all types of roms and kernels like wanam arhd omega phoenix pacman jelly bear pa and many other roms.
I have tried every single kernel. No problems on any of the combinations. Currently on wanam and redpill

I think the problem lies in the band of the wifi router. 5G seems to work fine while 2.4G(mine) need some tweaking to do.
Do you have a wifi router at home and what band is it?

I don't know the speed exactly but it says 54m adsl 2+ router.
Sent from my GT-N7100 using xda premium

Since the recent DMC3 upgrade, wifi connects fine every time. But the bug of decreasing speed over time, is still present.
This NEVER occurred with the 4.1.1 FW, so it's NOT router related. My router: Netgear CG3100 b/g/n 20Mhz bandwidth.
I was initially very happy, finding that the connection bug was gone in this FW, 'til I realised the speed problem wasn't.

Can you explain this "decreasing of speed over time" problem?

I mean that when I connect to the wifi network, the speed is 20-24Mbit/s down,
& 9-10Mbit up, as it's supposed to be. If I then leave the phone on the table for,
say 15-30 minutes, & after that pick it up and do a speed test, it has dropped
to between 2 & 3Mbit/s down, and around 3Mbit/s up. I disconnect from the
wifi network, reconnect immediately, and speeds are back to normal again.
Same every time. This bug, Sammy somehow failed to wipe out....

Wifi troubleshooting can be sort of a black arts. Regardless of where the fault lies, what you should do first is log into the router's control panel, and disable as many functions as possible, including setting it to b only, disabling qos, wmm and such, security to none, perhaps assign a static ip etc.
If it works, enable features one by one by process of elimination.

Not applicable, since the bug is not router related. (at least in my case)

not a single problem

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.

Same over here. I have 3 other devices on the same router and none have a problem. Restarting the router does not solve the problem.

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.

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.
