Rooted Using Kernels from Adrynalyne- Anybody Getting Slow Upload Speeds?

Sorry- I'm new so I can't post in the development section but I'm using the 4.3 versions of Adrynalyne's kernels and I'm getting slower donwload speeds and much slower upload speeds (closer to 500k). When I flashed back to the stock kernel the dl and upl speeds went back to normal. Anybody else getting this?

Kernel has absolutely nothing to do with your network speeds. That was likely a fluke.
Network speeds are affected by a number of things-signal strength and network congestion being the biggest factors.
Do several tests different times of day and you will see that 3g can vary from 30 to 2100 kbps download speeds. As for 4g.. Idk what typical speeds are, but it will have a similar range.

Thanks AdhvanIt for the response but I tried testing them within minutes of flashing kernels and did numerous tests. With stock kernel I was getting about 8-12mbs donwloads and believe it or not upwards to 25+ mbs uploads (and that's consistently) while with the Adrynalyne's ROMS (using different versions- a-c) I was getting about 3-6 mbs downloads and 1-2 mbs uploads. Granted 3-6 is good enough but the disparity between 3-6 and 8-12 for uploads and 2 and 25 is quite a difference. You mention that kernels have nothing to do with speed but I was wondering if undervolting has any effect on the radio? Is anybody else having donwload/upload issues?

The upload speeds on the speed test app are completely wrong. If anything, the Adrynalyne kernel brought it closer to what it should be. Tether the internet from your phone to your computer, then go to the speed test web site. That'll show you what it should be.

Tried tethering (which always seems slower) and got the same results with the 4.a - 4.3 kernels. If anybody is trying this kernel are you getting the same results? I really love this kernel and Adrynalyn's work is always top notch. I don't know if this is just my phone with maybe a bad radio?

that has to be the kernel.. check for updates... or try somthing different.

I'm all ears on the explanation of why it has to be.

Hi Adrynalyn. First, thanks for all of the work and time you put in. I can't post in the development thread or otherwise I would have posted this thread there. Also, thanks for checking in on the thread. Is it just my experience with the download speed using the 4.3 kernels? Thanks!

Im using his 4.3b and my speeds are fine. All his kernals have done well for me. As stated above 4g speeds should be around 7-12down and 4-6up. At least in NY that is the usual besides some slighty higher numbers once in a while.
I would redownload and try flashing again. Are you using rom manager to flash or going into recovery. I have done both and it seems fine...

Not to jack the thread... but
I am new and can't post in the dev section yet. Adrynalyn, just wanted to express my gratitude for all your hard work!!! Tried a couple other ROM's, but just LOVE yours and came back within minutes of each experience...

In my strongest 4g LTE area I get 15/5 pretty regularly on adryns kernels and from what I understand thats all your really sposed to be seeing...

Thanks to you guys for responding- it looks to be unique to my situation then. I'm flashing via recovery. Would that make a difference? I'm in San Jose and I had been getting incredible upload speeds- frequently hitting above 30mbs. My donwloads have always been lower but flashing with these kernels I haven't been able to duplicate. Maybe it's because I'm using the stock but rooted ROM? Jrocker23- are you using the stock rom, too?

Yes, all I did was root via adb and added Adranalyne's kernals. Im running .06 stock. Also flashing from recovery should work fine. Are you using setcpu or running with the stock kernal speed?

Funny you say this because I am in the San Jose area and before would hit 15-30mbs and now with adryns~ 4.3a kernel I get only 3/1mbs @ speakeasy website. This is rather weird.. Let me try a different kernel and report back with speeds.

Smok3d-
I'm also from the San Jose area. I was getting blazing uploads but now I can't get it over 2mbs. Something to do with our area's towers? Smok3d- could you revert back to the stock kernel? I did and was getting the regular speeds- I wonder if that's it too?

Ok there is definitely an issue going on here with kernels and speeds.
I was using Teslacoil with the included kernel and my speed in 3G area was snappy, when running speed tests I'd consistently get around 1.5 meg.
Yesterday i flashed the latest Virus rom with recommended Ziggy BFS kernel, and i almost automatically noticed my speed was running considerabley slower. When running a speed test, I'd get only around 100 KB down.
So today, i flashed the latest Virus rom again but this time i flashed Imoseyon normal lean kernel on it and now my speeds are back to 1.5 MB.
Now i know that speed tests are not accurate when run from the phone itself, however, the difference in speed is so dramatic that you don't even need to run a speed test to notice it right away.

And what is it with adrynalyne kernel that is the problem? I would love to know. I'm running it and my real speeds are great. You are running speed tests, bet if you didn't you wouldn't even notice the speed. Just because you are getting a certain speed from a TEST doesn't mean you will get the same in real world performance. Do research or provide facts before you make statements you can't back up

L00k above at my post... I automatically noticed my speed was considerably slower before even running a speed test. Then i change kernels, and its magically back to normal.
I'm no dev, so i couldn't begin to explain what in the kernel would cause it. And just because you aren't experiencing the issue doesn't mean it doesn't exist for others. Who knows? Maybe it was just a bad flash or CWR didn't clean cache properly before flashing, anything is possible, but we should work together to bring resolution to issues that arise, even if it is just happening to some...

[Q] WiFi reception difference between ROM's

Hello,
I'm using Senseless Extreme with good WiFi reception.
I have flashed HyperSensation-CM7.1-v0.7 and found out that WiFi reception become very very weak in the same settings.
Is there any chance to find out the difference in between those ROMs and tweak the Sensation CM7 to get better WiFi reception?
Thanks in advance.

i would assume that's depend on wifi driver - can it be ported over?

persiansown: sorry, i have not tried your rom yet.

some devs improve their wifi drivers for better range and whatnot. cm7 isnt fully stable and its devs havent put those things in yet. try Cdtdroids roms. he does em great!

the module for the broadcom wifi chip is in sense stock ROM, as well as firmware and fine tune parameters.
seems like on CM kernels there is no tweaks on that level, and for me that's kinda unusual (on my gentoo box it's a usual routine to build my own specific kernel)
or well, I have not tried Cdtdroid's roms so will give it a try
thanks

How are you quantifying Good and Very Weak ? If it's just the WIFI bars you need to realise that they have NO direct correlation with the actual signal.
It's easy to spoof perceived signal strength based on the bars shown.
Do the different ROMs you mention actually perform differently ?
There is a way to see what the RSSI value is, can't remember where it is in the settings. http://en.wikipedia.org/wiki/Received_signal_strength_indication

The difference is in ability to connect to the router from a next room, on one - I can comfortably browse, on another - I can not even connect to the AP.

Ahh, OK a real world issue. Hmm that's concerning.
Hmm, more digging needed. GL and I'll keep an eye out for any useful info.

Thanks a lot.
Drop me a PM if you need some testing.
I would love to see bare minimal ROM.

I think most of the sense roms have some improved wifi drivers over the CM/ASOP based ones.

MIUI-110280 build good reception
I am toying with MIUI ROM and the wifi reception is similar to SenslessExtreme and there is CM kernel.
so i think it's matter of the firmware and settings for broadcom wifi chip

Poor WIfi speeds with CM7.2

Hmmm, I'm in a bit of tough spot.
My Wifi speeds are horrible on a CM7.2 ROM. I'm using a custom rom (from cm forum) that someone built to solve the bad bluetooth headset profile that was regressed into the cm7.2 release. I need cm7.2 cause its' bluetooth also supports HID. Unfortunately, wifi speeds suck in this rom. I can't remember whether the cm7.2 stable had poor wifi speeds.
Does anyone recall what this wifi problem was, and how to fix it?
Thx,
rickbol

You could use smanager ads or pro along with v6 supercharger ( http://forum.xda-developers.com/showpost.php?p=18703418&postcount=5021 ). There is a 3g and wifi hack in that script.

It's actually in the 3G TurboCharger script, but it is on the thread you linked to.

Thanks, I'm reviewing those scripts.
Additional info... I disabled N support on my AP and my wifi throughput increased from 300-1000 kbs to a consistent 3000-4000 kbs. So that's alot better. But, CM7.2 wifi consistently shows a ~10DBm sensitivity deficit compared to another phone sitting next to it. Also, the Evo Shift stock ROMs sensitivity was more on order with this other phone. So I don't know if the sensitivity deficit is a bug, or part of the power\battery management.
I'm new to CM7.x, so I don't know how I can best test these thing. If I plug the phone in, does it automatically run in "Performance" mode for all features?
The issue I'm facing is I'm trying to use GrooveIP (VoIP) over Google Voice. I was having issues with this phone, and I beleive they were related to the wifi performance.
Any other suggestions for testing or debugging?
rickbol

As I continue to investigate this wifi issue, I discover that this CM7.2 has no tiwlan*.ini anywhere on the system. Other "slow wifi" reports mention using a CM6.x tiwlan.ini to fix CM7.2 wifi issues.
Can anyone confirm that a CM7.2 ROM should have tiwlan.ini? Where is it? The only file in /etc/wifi, /system/etc/wifi on this machine\rom is wpa_supplicant.conf.
What I'm really looking for is a ROM that: supports all the standard evo shift hardware stuff (inlcluding wimax), plus, bluetooth HID. It be great if it also improved on battery life.
Any contenders\suggestions?
Thx,

I don't know if you have any options with all those on the Shift.

If you are having trouble with CM7 not working well enough for you then stick with a STOCK based sense rom, every asop GB rom is based around the work done on CM7.

I would suggest strapped365's 2.77.651.8 [Rooted Stock-O.T.A] Rom, or Chad The Pathfinder's Stock Mod [SENSE 2.1 | 2.3.4]. There are quite a few others, these are just two of the latest that are quite stable .

Thanks for the ROM suggestions. I actually have the StockMod as my Sense rom for when I have to update Profile and PRL (I recently switched to Ting... so far, so good).
I've been able to poke around a bit down in linux on CM7. I'm suspecting the bcm4329.ko driver has some config wrong in it, but I don't know how to t-shoot settings really. Since the sensitivity is down by ~-10dBm, but otherwise working, I almost think misconfigured antennas or something. "iwconfig eth0" often reports relatively high "Noise level" and some "Tx excessive retries" although I don't have lots of 2.4GHz equipment competing for the spectrum (afaik).
Regarding the linux layer in Android, do both CM and Sense use pretty much the same implementations with regards to (wifi) hardware, or do they use different "management" interfaces? I guess CM is the one that departs most from "stock", but I don't yet have a feel for whether these departures are mostly in the Android layer, or whether they go deep under the hood into the kernel.
This "low-sensitivity wifi" issue is a widely reported issue thru all makes of phones and versions of (at least) CM, but I have yet to come across any positive diagnosis of the source of the issue (although, given the reports, I suspect a common cause). My hunt continues. Seems all the later dev of CM forgoes wimax functionality... and while wimax hasn't proved to be widely available, it does exist in my area, and 3G is so saturated that it's worth trying wimax when available.
Thanks for the help,
rickbol

HSPA 10 but not 15+

I know my area supports HSPA 21.
In Phone status, when not using data it should read HSPA 10. When you start actively using data, ex. during a speed test, it should bump up to HSPA 15+. Mine isn't doing it. I've tried with Jellybam, Dark Jelly S 10.1 Build 8.1, unofficial AOKP, and BB 7, with the 1.11 and 1.08 radios.
Can anyone else try it out and post their results with Rom, radio, location, and average speeds (not necessarily from current speed test, but maybe an aggregate of your normal speed tests since it can be so temporally different).

On Sense it shows Hspa (non active) then Hspap (while data is active). It is working correctly on Viper 2.0. My first time trying that ROM today. I have the wifi authentication problem. Resetting router didn't work, and looking into it I don't really want to downgrade Hboot as I prefer AOKP anyway.
What is it showing for you on AOKP/CM roms? Are you getting HSPA 15?
Btw, thanks for being so active in the One S forums. I've just been here for a week or two and you have specifically have stuck out. Cheers :good:

Not on AOSP at the moment but last time looked to see it said Hspap but that don't mean much here since the speed sucks balls. Just try all the radios you might find one that works for you.

The speed can suck just due to network congestion but at least it's trying to fire up hspap from hspa. Mine is doing the same thing on Sense.
I'm trying to figure out if it's just a visual bug on AOSP roms or if it genuinely isn't firing up hspa 15+

My speeds can vary greatly depending on the time of day. In evenings I drop to 700kb/s while midafternoon sits around 4-5mb/s. I have peaked to 9mb/s on the stock rom with the 1.11 radio. My first rom was JellyBam 4.1. I think I remember getting hspa+15 status, but I'm not 100% sure. Since I've tried $droyd$ unofficial aokp, bb7, DarkJelly 8.1. It's never visually showing hspa 15+. I think my speeds are the same, but that's just personal observation.

5Ghz Wifi low speed issue on all roms i've tested

Hi,
I've got an issue with the 5Ghz wifi on the 1+1. The Wi-Fi speed on 5Ghz is really low (0Mbps during the speed test). I've tested it on different roms.
The only solution I found to solve the problem and get a good speed is to go back on cm12 and install franco's kernel r43.
I would like to know if anybody knows if it's possible to extract r43 Wi-Fi drivers and make them compatible with cm12.1 nightlies?
Thanks for your help!

To be honest that is the first thing I hear about that. I have used multiple roms and always get good speeds.
Just did a quick test to a nas on my 5GHz network (Asus RTN-66U and a Linksys 6500) . 50MB file at around 8 to 12MB/s (megabyte not megabit!) which is more than fast enough.
I would try a different router if I were you.
Btw a good Asus router makes a difference compared to cheap stuff, not only in speed but also range.

Hi,
Thank you for your reply but I'm sure that the issue is due to the roms kernel. I have tested a lot of roms (sultanxda caf cm12.1 & 13, cm12.1 nightlies with stock and ak kernel etc...) and always the same issue : during the speed test (with the speedtest app from playstore) on my 5Ghz network the speed is really high at the start of the test (80Mbps) and then it decrease to really low speed (0Mbps).
I use my provider's box (Bbox Miami) and got a ftth connexion (1Gb) and as I said on my previous post the only solution to get a decent speed is to go back to cm12 and flash franco kernel r43.
With franco kernel r43 I get :
85Mbps DOWN and 92Mbps DOWN
Any help?

Then why can I just upload and download my 4K recordings constantly at max speed via airdroid or es-explorer? I am talking about a couple of hundred of MB clips.
My ISP speedtest via speedtest.net or the app is more or likely always maxed out at 100Mbps download, just did that test again. So for the money I would just get a different AP or router and use that. I haven't really seen anyone else complain. Just try it at a friends place or so.
I've seen plenty of crap wifi routers, both wifi and hardwired. The Bbox 2 which we had here in Belgium from an ISP was famous for being full of wifi bugs, unstable, disconnecting etc.
I also have a router here which does not give out an ip to an old laptop. (haven't wiresharked yet) but with all others it does.

I'm agree with you but why should I buy a new router? I'm on cm12 with kernel franco at the moment and it works perfectly 85Mbps down and 92Mbps up.
Maybe the stock cm12, 12.1 and 13 OPO's wifi drivers are not compatible with my ISP Box but I just want to know if it's possible to extract the wifi drivers from franco's kernel and use them with on cm12.1 or 13.

I'm om sultans latest 5.1.1 rom and I don't have the slow WiFi speeds you are having. With the speedtest.net app from Google play I get 185 Mbps down and 20Mbps up from my 200/20 connection on 5GHz. (Router 2m./ 6,5 feet away).
Maybe you can try to change your WiFi region code in advanced settings under WiFi if you haven't tried thuis already.

I've used these ROMs and my 5GHz AP lets the speedtest app max the connection, 55/5 nearly every time.
Whoa. Actually I just pulled 88.5/6.25 on a speedtest with my Asus RT-AC68U

No problem for me on sultan caf 340.
