2.4 ghz wifi issues

I'm having these issues too. Got the GSM Developer Edition on 11/29. It immediately updated to Kit Kat OTA so I'm not sure whether it had the issue prior to Kit Kat or not. This only happens on 2.4 ghz wifi and only with one of my routers at home, a Netgear WNDR3700v2 running OpenWrt Attitude Adjustment (I tried upgrading from Backfire to see if it would help, it did not). The other router is a Linksys WRT350N and when the phone is connected to that one the problem does not happen. Note, that there are 2 laptops, a Samsung Galaxy S2, and a Kindle Fire HDX that have zero problems with the WNDR3700. All can transfer data perfectly fine and at high speeds. Thus I do not think the router is bad. Have not checked work routers. 5 ghz wifi is totally fine and indeed very good with this phone.

For me, the problem is that the phone seems unable to receive data at high speed (over 1Mbps) on 2.4 ghz wifi in any area where the signal isn't perfect and sometimes even in the same room as the router (although usually it is fine there). Oddly in many cases when it has trouble receiving it can send data much faster. It almost seems like it might be some kind of interference as it is rather random.

At this point I'm wondering if the phone has a defective 2.4ghz subsystem, though that seem unlikely due to good transfer with the WRT350N, or if this is some kind of wifi tuning software bug in the phone.

Any info would be appreciated. Does anyone have this issue who did not have the issue on Jellybean? Am wondering if anything changed with wifi for the update? Note, I have tried clearing the cache in recovery as noted in another thread with no luck. Anyone have the WCNSS_qcom_cfg.ini file from Jellybean for this phone? Would rather not reflash just for 1 file.

Thanks.
[Moto X Q&A] Jexx11:
For what it's worth I have this same Netgear router and have had the same connectivity issues on both 4.2.2 and 4.4.

I did some reading today and found a couple possible fixes I plan on trying out. First one is to disable WMM. Secondly I found on the official netgear forums that they have had major issues (some of which you've described) with all firmwares ending in the .30s and went so far as to pull them from their download section.

My router was running firmware .36 and I successfully downgraded it to the latest stable firmware .12 that netgear now recommends.

Hopefully 1 of those 2 fixes improves the performance, at any rate I really think it's something with the router itself and not the moto x.
[Moto X Q&A] glimmer00:
Thanks for letting me know this was also an issue on 4.2.2. Saves me the trouble of flashing back just to test.

I will be interested to know if your using official netgear 1.0.0.12 firmware fixes the issue for you. I haven't actually ever used the official firmware as I've run OpenWRT since I got the router a year or two ago. 10.03.1 had the issue, and it appears 12.09 does as well. I may try a trunk build at some point to see if that changes anything.

I had previously written that all was well on the 5 ghz band. This appears to not be 100% correct. Yesterday evening and this morning I found myself "connected" to the 5ghz band without actually having working internet. Toggle wifi on/off fixes it, but I shouldn't have to do it.

Not sure if this helps, but on the 2.4 ghz side things do work better on one side of the house vs the other. Also it seems that I can get a very fast connection at times and then it stumbles and gets stuck going under 1 Mbps. I still suspect either a defect or some kind of low level radio issues with the moto or the router regarding interference from neighboring wifi access points (there are a lot around me, single family houses on small lots). However, keep in mind no other device has these issues but the moto. In the rare instance I venture into a bad signal pocket the signal indicator goes down and speed slows or they lose connection vs the moto where it can show excellent signal and have no/nearly no connectivity.

I haven't tried it for long, but switching to wireless g mode vs ng may improve stability though I only briefly tried it. I did walk around part of my house checking the Mbps with the app "WiFi Speed Test" and while way slower than N mode it was far more stable. Even if this does work it is a definate downgrade in speed though.
[Moto X Q&A] Jexx11:
Well its only been a day or two so it may be too early to tell, but so far my wifi seems much better after making those two fixes I mentioned above. This is on 2.4 band, the 5ghz band doesn't provide me enough signal strength to use all the time (router is too far from my bedroom).

The main issue I was having was my wifi signal would cut out even though it still showed a good connection. I could swipe down on the status bar and see no download arrow next to the wifi icon so I knew I wasn't receiving data. However a simple disconnect and reconnect to my wifi would fix the problem until it happened again. This seemed to be most common while watching YouTube videos, in fact it happened far too often which is why I went searching for a solution.

So as I mentioned things seem to be better for sure so far but I need to give it a week or so to see how much it is really helped, but so far I can't remember any wifi cutting out since I've made those two fixes.
[Moto X Q&A] atomus12:
I too have been having the same problem with my Moto X (VZW-DE, unlocked/rooted) on the same router you guys have been mentioning (Netgear WNDR3700v2). I also live in a condo area with a bunch of 2.4GHz SSIDs. Bought the DE when it first came out. Had the issue since firmware 139.12. None of the OTA updates resolve the issue.

It's random also, I can browse the web and it will randomly stop loading whatever I'm viewing or watching, I'll go check the status and the wifi is only trying to send data out, it just stops receiving data (only the UP arrow appears next to the wifi icon). Once this happens, I will turn wifi off and on again, and it's back to normal, until it randomly wants to do it again. The strange thing is, I've checked attached devices on the router config screen while my Moto X is having this issue and the device is no longer listed as connected under "Attached Devices", though on the Moto X it still has an IP address.

I've tried every solution but the most stable I can achieve is putting the Moto X on 5GHz only and connecting to 5G on my router. I also set my 5GHz to the highest channel (not sure what the number was, will have to check later when I get home) and I make sure Chromecast is powered off (for some reason I remember reading on a different thread/forum that this can cause an issue, not sure though and don't have link to that source) and so far it's been very stable.
[Moto X Q&A] glimmer00:
I agree it's somewhat random. With certain settings I can even get good speed sometimes with 2.4 ghz. Unfortunately, every combo has let me down in the long haul as I will go around the house testing and it will start stuttering for lack of a better word. Interference is definitely part of it as some areas are always better than others(oddly some bad signal ones are reliably good).

I mostly just use the 5ghz now which only has the issue maybe once every few days. Aside from that this phone seems very strong with 5ghz reception.

Will try a barrier breaker build on the router sometime in the near future but I don't expect it will fix it. I imagine this is something about the hardware of the router not working well with this phone. Bummer as its otherwise been a great router.
[Moto X Q&A] icon123:
I have this router with the same version. I don't have any problems but I run dd-wrt firmware. I was having other weird problems previously with a hacked kindle and 2.4ghz radio in the router. After I put dd-wrt on, everything has been great.
[Moto X Q&A] johnny grep:
Same issue here with a Cisco (enterprise-grade) AP & a controller. Will update the firmware on both soon. 5GHz forced was a permanent fix on mine, I suspect band steering is causing this as one SSID had it and the other didn't...

Sent from my Moto X
[Moto X Q&A] glimmer00:
It looks like this issue is fixed with the 4.4.2 update, at least for me. 2.4 ghz speeds are way better with my Netgear wndr3700 running opnwrt. I am currently running kangakat 4.4.2.
[T-Mobile, Samsung Galaxy SIII] henry8668:
Tmobile Galaxy III T999L.

I got the phone about 3 months ago and immediate rooted it using this guide http://galaxys3root.com/galaxy-s3-root/how-to-root-u-s-and-canada-galaxy-s3-sgh-t999sgh-i747sph-l710-fail-proofnoob-proof/.

In the 3 months of usage, I have encountered a few cases of the weird problem: during the call, suddenly the other party can't hear me while I can still hear the other party clearly. After called Tm support, they instructed me to reboot the phone every day to see if it goes way, then try to do reset to see if it goes away. I doubt this will help but still tried reboot it daily, it didn't help. Today the same problem repeated 10+ times! Very frustrated...

Anyone has similar issue or know this? how to fix it??

My questions:

1. Does the root have anything to do with this problem? (The root guide said it shouldn't, but just checking to confirm...)

2. Will reset the phone help at all?

3. It is still under warranty, if I want to warranty, I need to revert it to stock. Since I used odin to root, should I still use odin method to revert or I can also use TWRP or CWM Recovery method to revert it? (post #3 in http://xdaforums.com/showthread.php?t=2370981 )

hope some one can help me fix this issue and I don't need to revert it and get warranty way...

thanks!!

You said that the gpu clock remained at my set max, 504mhz, all the time, even after 68C, but you didn't say how hot it got.

Did it get hotter than that? I'm a bit wary of frying the board to squeeze out a few extra frames on my device, but that's just me.
[Galaxy S 4 General] 3ayachi:
Haw much does it take you to reach 68° ? I have the 9500 version and i didnt face that problem yet.. it s going warm but doesnt lag

[Galaxy S 4 General] nfsmw_gr:
You won't don't worry.

:)

Both the cpu and gpu have a tolerance up to 100C, plus the system automatically shuts down before reaching critical high temperature.

For me it didn't get much hotter, only a few degrees.

You can monitor the frequencies and temperature with the Qualcomm Trepn Profiler which is an advanced free monitoring app for Qualcomm devices:

https://developer.qualcomm.com/mobile-development/performance-tools/trepn-profiler

or

you can use this app by senior member [MENTION=3145598]rlorange[/MENTION] which is much simpler and gets the job done just right:

Sorry but this is not for the i9500, this is the first thing I wrote.

I don't even know if this happens on your device mate.

Anyway, it doesn't take much, play a heavy game for a few minutes an you'll reach 68C.

[Galaxy S 4 General] crazysoccerman:
So this won't work with a rooted s4 on stock rom and kernel?

If not I'm returning my phone. I played vice city today and the lag was terrible. I've only had this phone for two days and I'm dissatisfied with verizon and samsung for gimping it and then locking it down.

imo, companies advertising the power of their chips is false advertising when they set temperature throttle so low
[Galaxy S 4 General] nfsmw_gr:
No mate, I'm sorry.

But good news is Samsung WILL fix your phone no matter knox 0x0 or 0x1.

(confirmed)

So flash your device and try again! :)

I must agree, companies are full of crap when advertising their products, it's so furstrating! :@

This throttling issue happens with any device, including iDevices.
[Galaxy S 4 General] crazysoccerman:
Bootloader is locked. Most likely forever.

Don't have MDK so I cant loki.

Even with safestrap (which doesn't work for my MJ7) you can't flash custom kernels.

This phone is going back :good:

I'm going back to my trusty gnex for now. It would probably play GTA better at s4 resolution because I overclocked it and disabled thermal throttling.

Maybe I'll get a g2 with loki support...

Either way, I would like to give a Linus Torvalds Salute™ to samsung and verizon.
[Galaxy S 4 General] nfsmw_gr:
Too bad. :/

Wait for some exynos device or anyone with custom cpu/gpu because qualcomm imho isn't good enough.
[Galaxy S 4 General] crazysoccerman:
I got this to work on my s4. Are there similar settings I can modify to prevent cpu throttling?

Edit: cpu throttling settings exist. But it wasn't throttling... it was changing governer and minimum frequency.

I set the governer to performance with root explorer and it's working perfectly.

Thanks op for the location of the gpu settings. There was no way I would have found it without your post.
[Galaxy S 4 General] btmz:
I've tested it (works fine) but I have the feeling that somehow the phone is too warm
[Galaxy S 4 General] nfsmw_gr:
Glad it worked guys!

Well, the temperature will definitely increase because of the increased gpu clock speed, but as long as cpu throttling temp is <=85 you should be fine. :)
[Galaxy S 4 General] GlossGhost:
That's what I've been searching for all day, I knew this device can handle those games, but the random stuttering was painful.

It lowers the GPU to 128 MHz, I measured that when I played Apshalt 8 and got my TricksterMod set in background. When the game dropped massive FPS I switched to Trickster and saw that the GPU is running 128 MHz, shocking. Ktoon's kernel has a touch boost which works nicely but Asphalt 8 is a racing game that uses the sensors to steer and so I did not touch my screen so often and I need that.

You sir deserve a medal.
[Galaxy S 4 General] nfsmw_gr:
Thanks man!

I knew something was off the minute I started playing modern combat 3 and saw the same performance as my S3.

I researched quite a bit and found this in the end.

I even got in an argument with a guy at ausdim's kernel thread about this because he was saying I was talking nonsense and he wanted proof in order to believe me.

Well, here it is. :P
[Galaxy S 4 General] GlossGhost:
Ah, yeah no one can say to me that the games run buttery smooth without any modification.

A game does not run smooth on 128 MHz.

And all those amateur reboot your device and etc... They are complete nonsense.
[Galaxy S 4 General] mattiadj:
I want ask a thing before flashing... Is this only an unlock and gpu scales the frequencies as it needs or I have always gpu freq at max on depending on what I'm doing? I hope this only unlock the max frequency otherwise became e battery drainer hack! Tell me guy!

[Galaxy S 4 General] Formhault:
Alright, so, I have SlimBean (latest build) and KT kernel.

CPU governor : ktoonservativeq (also tried ondemand).

GPU frequency : maximum 504 MHz (also tried 545 MHz).

KThermal set to start at 85 Centigrades and stop at 82.

I installed Script Manager (and SMWidgets), placed the two .sh files on the internal memory, made a widget for each of them, then ran the GAMING ON script (tried both manually and via widget - just in case the widget doesn't work properly). Yes, it has been granted SU, so the script was working, as far as I can tell.

Effect? None. CPU never crossed 52-something degrees Celsius. Arcane Legends still stuttered like before (awful!). :(

Am I missing something...?

I checked the /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/min_pwrlevel file and the value inside is 0, so the script IS working...

Mostly an aesthetics issue, as the phone performs just fine, but I notice that the spots where there are openings in the gorilla glass do not quite match up to the main microphone and the earpiece. Anyone's that way, too? Slightly irritating, but the phone works just fine. It is probably completely unnoticeable if you have a black front, but it was one of the first things I noticed on my white Moto X.
