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.

WiFi keeps getting disconnected

Hello all,
i have noticed since the stock ROM and the new one i have put Domination HD the WiFi keeps getting disconnected every 5 minutes or so.. it connects automatically but it interrupts my video streams or downloads..
has anyone faced it and is there any fix?

I've had the same problem with 2 units.
Running CM9 now and it still does it. Pressuring AT&T for an exchange again....

Menu > Settings > Wireless & networks > Wi-fi settings > Press MENU button > Advanced > Wi-fi sleep policy
Change it as you desire. You probably have it set to turn wi-fi off when the screen turns off (default setting).

Had this problem too with my phone when it was new. I changed a setting in my router to allow a longer IP lease time and that fixed it. Set it for 2 weeks.

I'll give it a shot, changing the sleep policy in settings had no effect, it drops every few minutes regardless.

My wife's phone drops her WIFI connection about three times a day. I checked the option in WIFI settings (WIFI Sleep-Never), that didn't help and I tried messing with my router. Unfortunately I didn't see anything in the router setting about the lease and making it last longer. Where should this be? I have a NETGEAR that my cable company gave me.
p.s. Hey kkernaghan7, what's going on in your profile picture?

Sorry to hear that things aren't working. I'm not up to date with netgear routers but just search for IP lease time, it could be in the dhcp settings for the router. As far as my profile picture goes that was a picture that my ex girlfriend took, I think its funny.

WiFi/data issues

How's it going everyone. Just left sprint for T-Mobile. Even with the problems I'm having its still better than sprint crappy network. Anyways. For some reason no matter what ROM I'm on I'm having issues where the WiFi will turn off it will go to 4g than WiFi will randomly turn back on. Or I'll have great service than randomly I'll see an E near my signal bars and it slows down for a good 5 minutes. Any idea what may be causing the problem?

Make sure WiFi calling is disabled. Then go into Mobile Networks and change Network mode to WCDMA Only. See if that helps.

Well if you are getting the E, that's Tmobile's network for ya. It is quite spotty. I get the same thing and goes back to 4G soon after. One of my main gripes with Tmobile.
If you do what DocHoliday said, it won't work at all. Just won't have any signal at all. If you leave it to auto, you will at least get the EDGE network.
Did this do the same thing with your old phone? If not, not sure what the deal would be besides weak radio maybe.

Try using the Llama app to force wifi on and disable the radios when around specific locations?
That's a workaround though...

Its worth a shot. I had issues with staying on 4G when I first got the phone. That fixed it for me.
Spotty service depends upon your area imo. Sounds more like a network issue to me. Could be a side effect from all the refarming work they're doing on the network. Its a nationwide project so it can hapoen anywhere.
@op
If you turn off WiFi does it work as it should? If so check that WiFi calling isn't enabled and set to WiFi preferred. If it is turn it off and test, then if fixed turn it back on and try Cellular preferred.

Dude I had that same issue until I flashed lh2 roms. Havent had that issue with lh2 roms at all.. try stocked up or wildchilds xquizit.

For what it's worth, I had this issue yesterday out of the blue. Nearly every time I would unlock my phone, wifi would be disconnected and I'd see the 4G icon. After unlocking the phone, a few seconds later it would connect up to wifi again. And yes, this is even with wifi set to always on in the advanced settings.
I realize there could be multiple causes for this symptom, but the fix for me was simply forget the wifi network and connect up to it again and the issue disappeared since then. Hasn't happened today yet either.

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!
Sent from my Nexus 7 using Tapatalk 4

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.

Mine didn't at first either, but after update/reboot no problem. Now connecting at 150meg on 5ghz.

Still hit or miss for me. Sometimes its connected when I reboot. Usually I have to toggle WiFi on/off 2-3 times.

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.
Sent from my Nexus 7 using Tapatalk 4

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.

Same issue here. But i have to restart my device. Is it hardware or software you guys think?

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?

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.

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.
