Poor to none 3g speeds

So I'm fairly new to rooting and have been flashing a bunch of ROMs since I have and everything has worked fine but today I have noticed that I can very rarely get 3g in my house and a lot of the times its completely gone, I can't even get 1x. I have not messed with radios and I hadn't planned on doing so but what's going on here has anyone else had similar issues? I've flashed different ROMs after full wipes and still am having troubles. What gives?
Edit:
I am also getting really slow USB speeds. Like 10 minutes to put a nandroid backup onto my sd, this used to take a minute or less. What is happening and how can I fix my phone I'm going on vacation tomorrow I need it working

Do a full wipe in recovery, then flash this: http://forum.xda-developers.com/showthread.php?t=1087077
As far as slow SD speed, are you on an AOSP rom? If so, Chad's incredikernel will fix it. Look around on his thread, I think the latest release has it incorporated.

Yea I was trying MIUI so that's that problem.
Edit:
Whew you are a a life safer that brought back my great 3g speeds. I would like to know what exactly this did though and if I can flash new ROMs again and what might have happened to cause the problem.

Another cause for this to happen is that if u flash a Rom with Sprint source and u call the *228 it will mess your phone up and you will need to go back to the incredible official froyo to fix it... I had this issue my self ...

I thought I remembered hearing something about turning the phone on or off while in airplane mode causing this too, but I could be wrong. Glad that you got it working, if you have more questions feel free to ask.

I'm having problems with 3g as well. Has anyone tried applying this then going back to another rom?

It's my understanding that the GB leak fixes it, and you can go back to the rom of your choice after flashing it.

freedom kernel wifi issue?

Is there a WiFi fix for the Aggressive Freedom(universal) kernel?
I seem to be unable to connect to wifi, in networks it just says "Error" under the WiFi option.

From what I've read in the kernel's thread, it's the undervolting itself that's the issue, seems to cause problems with radio reception overall. So presumably going to a kernel that undervolts less aggressively should fix that, or at least help.
If it's an issue not related to the undervolting, then it'll be up to Lithid to develop a fix. Or you could go and download the source and try your hand at kernel hacking

Alright, I attempted flashing the other 2, more, less, and I tried Golden Monkey, all three of those don't allow my phone to boot... Quite disappointing, lots of work goes behind kernels and I am in no way upset with the kernels, just my phone.
Ima try the freedom stock kernel and see how that goes, but is there any special method to flashing a kernel?

Nothing particularly special. I wipe Cache and Dalvik-cache before flashing a new kernel every time and that generally seems to work ok. With the earlier Freedom kernel versions on MikG I found that flashing the stock kernel, wiping cache/dalvik and then flashing the new kernel worked better than just flashing the new kernel over.

Yeah, IDK what i'm doing wrong but none of the kernels will work for me. The only one that worked was Freedom-Aggressive, but I had no WiFi and it kept going to 1x, so I just a nandroid restore and im gonna stick with whatever synergy is running as a kernel.

I unfortunately don't have any personal experience running Synergy so I can't really offer much advice there. I'm not sure if there's a minimum number of posts requirement, but you could try searching through the thread for the kernel on the Dev. forum, and possibly post in the thread if there's no useful search results.

Yeah I don't have enough posts yet to post in the dev forum, but I have scoured the dev section for synergy and haven't found anything yet.

I am having the same issue I haven't tried more or less but I have tried golden monkey, both aggressive freedom universal, and godmode. They all seem to break wifi and 4g on synergy rls1 with godmode, on my phone. I had some luck with the aggressive freedom godmode kernel however my superuser app, setcpu and benchmark app kept on force closing. Ever since then every time I reflash it, it always breaks wifi. I am somewhat new to all this and have spent days reading through posts and haven't found much of a solution. I would love to figure this out because with either aggressive kernal (godmode or universal) my phone is super fast. I am almost and I mean almost ready kiss wifi goodbye but I would like to find a solution. If anyone can help I would greatly appreciate it.

Yeah, I know what you mean. I would really like to find a fix for the issue or find someone who may have a way to fix it. IDK though, my evo won't flash any kernels with Synergy RLS1 + godmode. Got it to work once, but after I flashed to the back up since WiFi didn't work, my phone just gets stuck on the htc screen.

I'm just so new to all this, and work so many hours its real hard to spend any time figuring it out. I won't have much time this coming week to do much with testing but I will try and get as much info and kernels tested to find out which work best but so far the 3 I have tried wifi won't start and says error. Sux cuz my phone is so fast with aggressive freedom kernal

Knight,
I would suggest going to synergy rls 1 ( the regular version not godmode) it seems a lot of phones dont like god mode but run smooth as butter on rls 1.
I am running synergy rls 1 with golden monkey universal kernal. no problems with wifi. Cant test 4g as I am not in a 4g area.
Hope this helps

Thanks I will try that later on tonight.

Ok this is the best advice i have read so far.. i was having major issues flashing kernels.. when i could get them to work, wifi was not working and neither was 4g. So i flashed over to synergy +godmode, and it was so slow and sluggish with the stock kernel on my phone.. i tried freedom aggressive, golden monkey, netarchy, and while they all made my phone much more responsive and fast, i still had issues with 4g and wifi.. So today i found this, and flashed over to the regular synergy without godmode.. Already i can tell a huge difference with the stock kernel, it is very fast and responsive. I am flashing over Freedom aggressive to see if wifi and 4g work, crossing my fingers, if not i will then try golden monkey..
*******Update***********
OK merchmonster, you sir are awesome.. I can confirm wifi and 4g working with synergy rls 1 no godmode, and freedom aggressive universal.. Very awesome!!!!!!! If i could thank you a thousand more times i woud!!

I had to replace the freedom aggressive kernel due to my wifi stopped working a few days after flashing so I wanted to put the stock back on after flashing and during reeboot it gets stuck on the white htc evo 4g screen. I wiped dalvic and cache 3 time first. Any ideas?

[Q] Phone randomly reboots with Calkulin's ICS rom

Hey guys,
I've clicked around a bit but can't seem to find anyone with the same issue, and I went through about 40 pages on Calkulin's ROM but I really don't want to go through all 200 and some if somebody here can provide a solution.
I've used his ROMs for the past year, really fantastic, no complaints at all. I flashed his beta ICS build a few months ago and it worked well with the exception that it would randomly reboot for no apparent reason. I could be in the middle of a text message or it could be sitting on my desk and all of a sudden, reboot. I went back to his old ROM and decided to put off ICS for a few months to work out the bugs. Today I put his newest ICS ROM up and once again, random reboots. It doesn't seem that others are having the same problem so I'm not sure what to make of it. And for the sake of putting it out there, it's always a clean install - Format All, flash modem and ROM.
Anybody have any ideas? Suggestions? Any help is seriously appreciated.
Thanks guys.

Ive heard of someone else having this issue before have you tried a fresh install with a new download of EL29 or EL26? When i have had issuez in the past that could be the culprit try a new download also you could try one of the new kernals posted that may help as well.

Are you using 4g?? This is a known issue with leaving 4g enabled.
Sent from my SPH-D710 using XDA

It is a known issue that if the hacked Hotspot is installed and you are running on 4G that you will experience random reboots. Mijjah74 has implemented a fix for it in his ROMs and it is beginning to go out among the other developers as well.
Until your developer implements the fix the cure is to not use 4G.

Awesome, thanks a ton. What a goofy bug. Yes I frequently use 4g, hourly even, and although I rarely use the hot spot, it is installed. I wonder if un installing it would fix the issue.
Thanks again.
Any idea if using am older modem would fix it?

No, reinstalling won't help. I was testing 4g for this and (for me at least) it would reboot at about exactly the 1 hr mark if 4g is running constantly. Pretty strange but it did it several times in a row that way. I think someone said that they have the timing down pretty well and I can't recall exactly what the recommendation was, turn 4g off and back on right before it's going to reboot (you should time yours to see when it does it). Something like that.
Addendum: FYI, I'm running stock EL29 modem. A different modem won't change the 4g reboot issue either, sorry.

I had random reboots on every ROM. I went all the way back to stock unrooted, and started back over. Haven't has any issues since.

Intermittent WiFi Stability on AOSP

Hey everyone, just came over here from the HTC One X ( AT&T ) forums, smashed the screen on it and used an upgrade to get an AT&T SGS3, loving it so far. Had it rooted and custom recovery, and was on a custom ROM not even an hour after getting home. Anyway, onto the main part of this post.
I tried CM10 ( the 11/01 and 11/02 nightlies), both of the AOKP, and LiquidSmooth, and on all of them, my WiFi stability is not there. It seems to disconnect at random, if connect at all, and when i walk out of range of the router, and then come back, it will not automatically reconnect until i go into airplane mode. Trying to turn WiFi itself off and back on does not work - it won't turn off/back on, it sticks at what it was at.
TouchWiz ROMs, everything works just fine. I'm pretty sure it was working on MIUI as well, but i didnt have MIUI on there long enough to properly test it.
I am using the UCLH9 radio, since AFTER searching the forums pretty in-depth, i found that all radios prior to UCLH9 had wifi driver issues. Flashing this new radio did NOT fix the issue.
I have tried both stock CM10 kernel AND Ktoonsez's kernel (which is pretty freakin awesome, btw! :good: ) and still have WiFi problems.
I have tried flashing ROMs through both TWRP and CWM Recoveries, and have done a full wip of /system /data /cache and /dalvik-cache 3 times each before flashing a ROM.
I'm a pretty competent at flashing ROMs and troubleshooting problems, I am a pretty well-known beta-tester for multiple Sense and AOSP ROMs over at the One X forums, and I have a very good knowledge of how to work ADB and Fastboot. I've been around XDA for a little while, and I know the way of things around here. (don't want you guys thinking im just another a$$hole that threw a post up the second a problem occurred without doing some research first!)
If anyone has ANY ideas as to what may be causing the wifi drivers to crash, PLEASE fill me in.

I've tried all the same things you have and have had no success. The best wifi stability I got was the AOKP_d2att milestone1 w/ lean kernel combination, but wifi would stay connected for 3-5 minutes as opposed to 30 seconds.
I briefly tried CM9, but that still had wifi issues. I might try a few other ICS roms
I came across these threads that documented the problem across other phones:
code.google.com/p/android/issues/detail?id=34942
code.google.com/p/android/issues/detail?id=36993
I've decided that I'm stuck with ICS until the official JB comes out.

Well, I flashed Intergalactic, which is a modded Stock ICS TW ROM based on the AT&T firmware. Shortly after, I reinstalled TWRP recovery and flashed task's AOKP with ktoonsez's kernel, and WiFi works!
This is similar to an issue we had several weeks back with CM10 based ROMs on the HTC One X, you couldn't get LTE unless you flashed a ROM based on Android 4.0.3, it was something with CM10 obviously, because it was fixed in one of the October nightlies iirc.
Try flashing intergalactic and then task and ktoonsez aokp and see if your WiFi is working and let me know
Sent from my SGH-I747 using Tapatalk 2

Nope, no luck this way either.
Wifi under Intergalactic works fine.
TWRP flash AOKP milestone 1 alone, with the ktoonsez kernel, or with lean kernal and my wifi still hangs after ~1 minute of inactivity. The phone grinds to a halt. If you can get to the settings, it says that I am connected to my router, but shows no signal bars. If you can then turn wifi off, the phone un-freezes, and (except for no wifi access), the phone is back to normal. If you now turn wifi back on, it stays up for another minute or two and goes down again.
I'm open to any other suggestions.
Thanks though

i am using task and ktoonsez rom....when i first installed it, i noticed wifi dropping, it was annoying.
kinda dont happen anymore. The only 2 things i can think of that might have helped me is; i flashed a new modem i747MVLLE8(I'm with rogers), and under Wi-fi(menu/advanced), i unchecked poor connections.
also my router is 2.4ghz and 5ghz band, but i am connected to the 2.4ghz band.
hope it helps somehow.

I had horrible dropouts and speed with my last WiFi router. I forget the name/model but it was a new model (released this year) that had great reviews.
I went back to my old router and all my wifi problems disappeared.
I do get dropouts once in awhile still. But I haven't done a clean ROM install in awhile.

WiFi behaving erratically

Hey Guys,
lately my wifi is been acting strange, I have full signal when the phone is idle but the minute I start using it the signal drops to a 1-2 bars or just that dot.
There are times it just disconnects from WiFi and connects after a brief moment with full signal. I am noticing this behavior when I do something WiFi intense. How can I get to the root of this problem?
I am currently rooted, running MMuzzy ROM with Trinity kernel. (I tried stock kernel too and it acted the same)
Any help appreciated.
Thanks

Have you installed the latest radio? :S might be best to do a clean install (google image)
edit: You should try with different kernels aswell it might be possible that trinity isn't acting well with your phone not that i'm bad mouthing trinity .

I'm on the latest radio, I tried various kernels and they all act the same.
I'll have to give Google's image a go.
