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

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.

wireless issues (intermittent)

anyone got weird intermittent wireless issues?
Every now on then, and then seemingly only on some apps, wireless network connectivity will come to a crawl and / or seemingly stop completely. Apps time out etc. but I know the network is fine as my flatmate's galaxy nexus / my laptop remain fine. The most common culprit is the play store. I turn off wireless and go on HSPA, wait a while, go back to wireless, all good.
Also, once I had to kill chrome beta to fix it.
What gives?

I am having some minor wifi issues too, but i think they are slightly different from wintermute's problem.
Both my wifes and my One X won't reconnect to our wifi after returning to the house. The only way I have been able to get them to re-connect is to reboot the router.
The One X's try to reconnect appear to, then instantly disconnect and just keep cycling. Turning the wifi off and on doesn't seem to help.
Our Asus transformer and the laptop don't seem to have any issues if taken out of wifi range and then moved back in.

Hi there's a few forum posts about this. A number of us has had this issue...the One X would not have good WiFi speeds, or would completely stop whereas all other WiFi enabled devices on the same network at the same time would be fine. A reboot of the router seems to fix this for most of us. Doesn't quite make sense why the One X would be affected by a wifi issue but not other devices, but seems to do the trick for most people. Its been 7 days now since I had my One X, and since rebooting the router, the wifi issues have not returned.

I'm a cisco tech in real life and trust me its not my wireless setup... proof is that all other droids work fine (my old nexus, atrix my flatmate's galaxy nexus etc.) unless there is some super esoteric setting that the HTC one requires
having said that I have rebooted my WAP a couple of times (in addition to tweaking my router a bit re: IOS firewall, some tcp-mss tweaks I was using etc.) and it does seem better. Still at a loss to understand why no other device has any issues except for this

I'm seeing wifi drop and reconnect all the time on my One X.
Signal strength isn't an issue, I'm sat 3m from the AP however their are lots of wifi networks in this building so could be an issue with interference...
I don't have any issues with my laptop or old Desire on this wifi..
I see the same issues at the office but again their are lots of wifi networks at that location too...

Hi there,
I had a problem with my HOX and my German Fritzbox Router...it would connect, but then not letting any data through...and then even disable the whole WiFi signal so that my laptop, ps3 and Samsung Tab did not get a connection anymore...reset of the Fritzbox was necessary....loads of HOX user reported the issue in a German forum, and one suggested to set the WLAN signal from b+g+n 2.4 to only b+g 2.4 and voila....problem has disappeared...price is that connex max at 54 Mbits now...but I can live with that...try it...maybe it solves some people's WiFi issues...until someone or HTC themselves figure out a working solution with a full wireless n support...

I am experiencing the same issues but with the one s, not the WIFI ones the actual network stops all of a sudden and usually within 1 minute comes back.
It happens about once a day.

The only real problem I have is with the WLAN stick which I use on my pc as hotspot. My Phone connects but after a few minutes I have to restart WLAN on phone so it works again. With the router at my parents home (Fritz-Box) I dont have this problem. I use connectify lite on my pc. With the built-in hotspot in windows 7 it just wont work out. Maybe someone else have this kind of issue and knows a solution.

I have the same problem at home and at work.
Disabling WiFi-N on the AP fixes the problem.
At the office we have Netgear WNAP210 and at home I have a Draytec Vigor 2710VDn

Can't quote xda app giving me invalid thread id error, but I have the same exact issue at work, the linksys wag120n router I use as wap, connected to a net gear router, most times when the phone disconnects, and only the hox, it takes down the internet for even those pcs connected directly to the net gear router, strangely I only need to reboot the linksys router to get things working again.... Weird.
I think the hox is doing something, like sending repeated dhcp requests (as in a bug on hox) and taking out the dhcp server. Although of course various routers would behave differently to this. My home network is fine. Not affected ever.

Galaxy Note 2 Wifi issue

This is pretty strange so I thought I'd check here with people.
I got my new Sprint Note 2 today. When I was at home it connected to my wifi network and worked fine. When I got to work I connected it to our wifi network and the internet won't work. If I turn off wifi internet comes back.
Here's the kicker, I have my old iPhone right next to it connected to the work wifi network and it is connected fine to the internet. This is definitely going through wifi as I no longer have a data plan on that phone.
I checked with our IT admin who said that there is no need to "accept" a device on our wifi network. He also rebooted the network for good measure. After both phones lost the network (from the reboot) and reconnected the same thing happened. No internet from my Note but internet works fine on the iPhone. Restarting my Note doesn't fix the problem.
Any ideas? Thanks.

I have the same problem. Need help too.

My network admin created a second wifi network to connect to (I guess our router supported it) and when I connected to the new one I got internet.
If it helps others try and solve the issue he tried pinging the IP address that my phone was using and said that he could only send information but not get anything back.

Try changing your wifi channel config in the router.

Hi, I've got the International version N7100 and experiencing weird wifi problem. I have tried to reset my wifi router and use static IP but it doesn't solve the problem. Btw, the problem is whenever I connect my Note 2 to wifi it would lose connection after a while then messes my router and connection of my PC to router as well. Never had this issue until I brought the Note 2 home a week ago. I had to restart my router and turn off my wifi on Note 2 for everything else to work. My iPad, iPhone and PC are all doing fine when Note 2's wifi is off.

I used to have terrible problems with my Virgin Superhub which all went away when I changed the security settings to WEP hexidecimal from WPA2-PSK (AES). Laptops and phones would have intermittent connections all the time which a reboot or channel change would sort out but only temporarily. Give it a whirl.

I've been experiencing the same problem. It's especially annoying when I try to download big size apps on Google Play ( > 1 gb) because it will stop any moment and i will have to re-download it over and over again. It never happens when I connect to school wifi but it just happens when I connect to my wifi at home. Weird. Nothing is wrong with my wifi at all because my other computer is always connected 24/7 without any problem.

I have a similar problem on Omega Ron v5.0 with latest Andrei kernel. The phone gets stuck sometimes in getting IP address part or have disconnects. It's annoying.

Afraid not.
I did that after other efforts failed but still have to go through same issue every now and then. This is not a permanent problem but something that occurs at least once a day for me.

Also having Wifi issues with GN2 from Sprint
I got the GN2 on it's release date (this past Thursday) through Sprint. Got it home got set up, connected...everything worked beautifully.
After a couple of hours, downloading apps etc. I noticed it had stalled. Turned off WiFI and used the network to finish. Turned back on WiFi and Voila, action again, but a few hours later it stalled.
I first made sure all of my settings were in agreement. No sleep mode or anything like that was enabled. No power saver either.
Couple hours goes by, WiFi connectivity stalls (even though it shows a full signal) I contacted TWC and made sure it wasn't the modem/router. I changed the wifi channel, tinked with the bandwidth... everything worked...an hour later it stalled. Called Sprint they said I had a dud, took it back, exchanged it, got the new one... SAME ISSUES. YEsterday I connected to my Church network HOPING it was an issue at home, but not so. After an hour on the network it stalled.
Contacted Samsung today and they have had no complaints according to them so i said I'm happy to be the first... If anyone finds a fix please let me know.
PD

Do you have any solution yet? I have the same issues with 2 different networks. I already contacted Samsung, but they only say I should do a reset of my device and read the setup instuctions for wifi. I'm still in contact with Samsung and hardly try to get a solution.
Stay tuned, I'll post any news I can get.

I'd prefer it to work with the stronger encryption of WPA2 rather than WEP.

OP: it will be great if you could add a poll to the thread as that way we can see whats the percentage of users are experiencing this issue,

Same issue here. Connect wifi and I'm able to hold connection for as little as minutes at times. Turn back on 4G and I'm fine. If I re enable wifi straight after it works intermittently. This is true of both my home and office wifi. So I'm lead to believe it's the phone.

Hi,
Almost the same thing here. everytime I go out of my home and comeback the wifi network seems to work but no internet access. I have to stop and restart wifi then it works.
very strange issue. ok I have a work around but I'm going to open a ticket to Samsung.

Same issue - connects for about 30 seconds
I've tried on different routers. Other devices (iphone, ipad, S3, etc.) all work fine. Sees the wifi network. connects, then disconnects and TURNS OFF WIFI. I can't figure out how to go to service mode to see if this is a timer issue. I've tried on both G and N networks. using a verizon fios, actionteck router (and netgear). Also, will not remember the password credentials. tried router reboot and fidling, etc. Driving me nuts. any suggestions ???

[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.

Only had the phone a day so haven't seen this yet but i did get it randomly with my G3. I could never figure it out. A quick on/off of the Wi-Fi fixed it quickly. Router is Netgear Nighthawk. About 8 other Wi-Fi devices in the house and never seen it on anything else.

I've been seeing this on my H811. It's nothing major but it does cut off then quickly reconnect after several seconds.

Mine also does this on the T-Mobile version.

H810 here. My G4 seems to strongly - and I mean really strongly - favor mobile data. My house is festooned with wifi access points and yet my G4 often turns its wifi radio off and I have to manually turn on wifi, then manually connect to a nearby access point. As I move through the house, rather than connecting to an access point with a better signal, it shuts the wifi radio off, altogether.
The G4 has shut its wifi radio off while I've been in the process of selecting a wifi access point. It's shut its radio off right after I've selected the access point I want and while I'm booting up the web browser.
Today, at work, the G4 is continuing to seemingly randomly shut off its wifi radio. When I manually turn it on, then select the access point, I find the phone has forgotten the password.
Very frustrating.
As an experiment, I have now shut off mobile data, to see if that will coax the G4 to seek and maintain its wifi connection. But there's no way I'm going to spend my day turning off or on mobile data, wifi radio, etc. I'm already manually turning Location on and off, to preserve battery power.

had wifi issues on the 2 g4's i've had. sent first one back due to damage to back cover on arrival. Glad its not just me having wifi issues

Having these issues as well. Rebooting my router sometimes stops it from happening, but quite frustratingly, the phone gets very hot (and discharges quickly) as a result. Have had a hot, dead phone before.

Most of the WIFI routers have different type of connections G / N / B, The N type is not a !00% compatible with our G4, therefore I suggest you to change to B/N, after I change the protocol, I havent see the WIFI issue so far.

I had Wi-Fi disconnects because I had turned on the advanced option to automatically swap to Mobile data on weak Wi-Fi signal. After that was turned off, the Wi-Fi worked as it should.

Every instance of SManager is my wifi reconnecting randomly in the house yesterday at my desk.

I have had this issue on my H811 since new. It does it more on 5 Ghz than on 2.4 Ghz, but it still happens. It's more common at home with my Asus router than at work with the Cisco APs they use.
After the latest update I have noticed that the iPod touch I keep in the car disconnects from the hotspot on the phone way too often. This never happened with the previous build, but I also didn't have xposed installed before. Has anyone else noticed any issues with their hotspot?

I got an LG G4 on Friday in the UK and it is running version 10D.
I am encountering this issue and I am finding it extremely annoying - did anyone find a resolution?
It is so frustrating it is getting to the point where the phone will be going back for a refund. It does it at any location with WiFi I go to, so I know it isn't a configuration issue on my WiFi at home.

I'm having this issue too all of a sudden. First thing I noticed was excessive battery drain. But every few minutes it connects to a different ap in my house. Other phones and devices don't do this. Time to dig.
