I have noticed a HUGE drop in network speed since flashing a new kernel. I'm talking a drop from 1-1.3mb down to 300-500kb. What gives?

Bump. Kind of interested in the answer myself.

I'm not sure if its the kernel.. when I rooted my phone and changed rom, I indeed had double the speed I had stock. I asked this a few times around here and no one replied.. I notice with true static kernel I go into data roaming. Again Not sure. But when I had and will switch badlck to is snap 8.1 850. So I'd like to know this too..

Make sure it's not something simple as testing at different times of day. Testing late at night or early morning and you'll always see fester speeds with less network traffic.
same here - the drop in speeds for me hasnt been as bad if i using a cm6 nightly but if i go back to sense rom the speeds are horrible
I've been continuing to test my speeds throughout the day, even on different servers. My download speed has struggled to reach 1.0mb on maybe one out of 10 times. The biggest problem I'm seeing is my upload speed. It seems to be VERY unstable. Usually the test will freeze and then when it ends my speed ends up being something like 50kb. I've been on Calkulins EViO 1.1 for a while but I've been doing quite a bit of kernel testing. Right now I'm on King's BFS #8. I think when I get some time later I'm going to do some actual tests. I also installed and backed up the new Fresh 3.2 with the newest HTC stock kernel so I'll probably give that a try as well.
If you are using Setcpu try putting it in performance mode at 998 MHz or higher and see if you get better speeds. I have been doing some testing as my house is in a week signal area. It turns out most, if not all of these kernels are undervolted. Good for battery life, but it seems to reduce the radio's sensitivity. At my house I lose signal whenever my speed drops to 245 MHz, which indicates to me that the radio is not getting enough voltage to lock the signal. I could be wrong, but it would be interesting to see what you guys get if you force it to not drop the voltage. I think most of the kernels keep the voltage stock at 998 MHz or higher.
speeds across kernels & set cpu settings
This isn't the most scientific comparison but i would like to know if others are finding similar results. (i am located in NYC and still trying to figure out why sprint still doesn't have the 4G network running here - I know its up in a few small pockets..)
I think all of these results are pretty sad IMO - with that being said there seems to be a boost in speed when using setcpu at the performance setting:
The first three were run on Fresh's Newest 3.2 release (Supersonic 3.28.651.1) and the rest on CM6 final
Wiped cache and dalvik between Kernel swaps -
Round 1:
Fresh's newest kernel w/ no setcpu - average speed of 666 kbps down
Fresh's newest kernel w/ setcpu on peformance (998) - 849 kbps down
Round 2:
netarchy-toastmod-4.1.8-cfs-bfq-fresh-compatible- no setcpu -615 kbps down
netarchy-toastmod-4.1.8-cfs-bfq-fresh-compatible- setcpu (119)-758 kbps down
Round 3:
KiNgxKernel-Evo-8-BFS318-2.6.32.15- no setcpu - 609 kbps down
KiNgxKernel-Evo-8-BFS318-2.6.32.15- setcpu (119) -730 kbps down
Round 4:
CM6 FINAL - stock kernel - no setcpu - 908 kbps down

I think the problem is just fluctuation in network speed. Also the other problem is the speedtest.net app! It is so freaking inaccurate yet everybody seems to like using it.....instead I recommend the xtremelabs.app in the market. I hear the website for speedtest.net is more accurate though. I have seen my network speeds flex from 300kb to 1.5 mb in my house.

New Sprint OTA 3.28.651.1 - HUGE DIFFERENCE
I just went back to the stock New Sprint OTA 3.28.651.1 - that flipz released a few days ago:
http://forum.xda-developers.com/showthread.php?t=773444
and my speeds are now between 1.2 and 1.5 on 3G - as compared to 650 - 700 kbps on the custom roms and kernels... might be worth looking into for those who are having issues.
I've bin pretty disapointed with the roms signal and service strength on my G2 lately.
When I bought my fone I had full 4G bars all the time in my area and at home, so it can't be that "towers" moved or network error. I can explain why.
First with stock rom I got it all bars, rooted and everything.
I notice the signal change once I jump to a rom first was virtuous, I get 3G all the time..speed test sucks and it sometimes goes to edge. It goes to 4G once in a blue moon...for only like 6 seconds max. I swear.
Than I go back to stock "backup" and my signal strength is back to awesomeness and check speedtestt and they're out of hand perfect.
So I stayed stock for a bit, tried other roms and same crap.
Stayed stock for a bit more longer, now on cm 6.1.1 and its not as bad as it was but its really bad still. Edge is on as I speak at a spot where 4G is full strength all the time at my house.
I need help figuring out what's the cause? Is it a kernel? Or something? If so can I flash the stock one for it on the cm so I can have my stock speed since its the best?
Or what can it be?
Pleeeaaasee help ! I wanna enjoy this rom,but without excellent signal/service strength it means nothing at all to me but back to boring old stock...
Thanks..

did u check ur apn?
Not really, but it shouldn't have bin touched since the apn isn't in stock.
Just don't get why all of the custom roms have bad service but when I got back to stock with root and all the service goes back to being excellent again.

Compare 6.1.1 and stocks build.prop files
Maybe you will find your answer there?
Another point to make is that the stock rom doesn't show a 3G icon.....it just displays the 'H' icon regardless of whether you are on 3G or 4G.
So when using the stock ROM, you just *thought* you were getting 4G all the time when you were actually only getting 3G connections.
On the non-stock ROM's, they actually differentiate between 3G and 4G. Thus you get to see when you are 'really' using 4G and the few times you actually get 4G speeds.
It's all a marketing game by the providers.

Your right, the stock rom doesn't differentiate between umts n hspa. But one thing I noticed is that all rooted roms have a slight lag when switching from umts n hspa.
I can totally attest to this statement. Stock data access speeds and signal is much better than custom ROMS. It must be something that is missing in the kernel or maybe the ROM itself. Dont think it is the radio because no one has mentioned flashing another radio in any of the stock roms list so far.
I am on CM 6.1.1 right now and I really want this ROM to have the same signal as the stock....
I have the same thing on mine. When I tried cyananogen my signal was crap. I would get slower speeds and less service overall. Same for MIUI. Couldn't handle it and went back to stock. Not to be unapreciative to rom developers but its hard to beat stock connection and battery life

Wish you where right, but I wouldn't post this up if it was just that.
I tested the speeds out with speed test and my results cleary show that stock has perfect 4G speeds. also used tethering and on my ps3 it loses connectiong with custom roms. When usually it doesn't . So, it couldn't be that. Download speeds and everything lags a lot, and I go to edge awhole lot where I'm at when I'm always in 4G.

I have owned many diff types of android phones. And all were rooted with custom roms and all exhibited the "laggy umts to hspa switch."
might be something we r gonna have to comprimise...
On an unrelated note. My n900 from nokia is capable of hspa plus but only till about 10mb where as my g2 can pull in about 14mb. Today I noticed that the n900 consistently hovers around 5-7mb per second where as my g2 hovers around 2mb-4mb per sec lol.
Can't wait for the nokia n9.
I'm confident your answer is in /system/build.prop. Check the HSDPA and HSUPA categories.

Is it possible, that everyone that owns a G2 having this problem but doesn't notice it?
We need to let people know.

It's gotta be something in the software, a setting gone awry or accidentally unnoticed, a line in the kernal code or something.
Eventually CM or someone will figure it out and we'll enjoy "4g" speeds even while ROM'd up.

I believe its in the build.prop file. Rodriguezstyle once released a beautiful black n green rom for the nexus one. It didn't exhibit the umts to hspa lag. I remember reviewing his build.prop. it was definately very different from what I have seen in the past

Is it possible to port his build.prop into one of our existing ROMs? Maybe that'll fix the problem.
Ive compared the build.prop files from a stock backup and 6.1.1 and there's nothing in there in the communication settings that would be causing this. They're literally the same going down the list.
It must be the new radio 6.1.1 uses which isn't the Tmobile stock radio. That's the only thing that could be affecting communications (bars and data speeds).
But I agree I'm seeing similar results i an HSPA+ area where Speedtest seems to get stuck and wobble around 1.5mb down like its some kind of cap or something. Haven't seen a huge signal bar drop though.

Yes stock ROM to CM 6.1.1 was what I meant. Nothing different in build.prop that would affect the radio portion. Just some memory tweaks but that would have nothing to do with the signal or data speeds.

Oh ok. Sorry for the confusion.
After the new g2 update I actually got stronger signals n better data speeds though. I don't think downgrading the radio will help....
But its worth a go I guess
What is your 4g speed on your device?

to get a better idea, we should run the speed test 3 times (take the average) at a few different points during the day (morning, afternoon, evening, night?) in the same place, then take the overall average... this will give you a more accurate whole picture.
might be a good idea to put where you live in there as well.
using the above method (3 simultaneous tests, 1 morning, 1 afternoon, 1 evening, 1 night), my results are as follows... both radios were tested in the same location at the approximate same times a week apart. I'm in eastside seattle:
26.02.01.15:
DOWN: ~4.8mbps
UP: ~3.5mbps
26.06.04.27 (w/ updated lib files):
DOWN: ~5.4mbps
UP: ~3.9mbps
noticeable (not just placebo effect) decrease in browser loading times and GPS is much better for me. switching from towers seems to be quicker as well - my phone used to hang for 10-15 secs going from 3G to H, now it's almost instant even in the middle of communication. have been extremely happy with 26.06.02.27 so far... I may try some other radios just for testing, but I'm scared to screw up what is already a pretty solid setup.
You should also note that just because your phone has the "H" icon in the status bar, doesn't mean that you're on the "4G" network (which technically is HSPA+). The H can refer to HSUPA (instead of HSPA+), and it will often stay on H even when you're down on UMTS (3G). I don't even have HSPA+ "4G" in my area, being told that its on the way in the coming months, and H is lit up all the time, but its just HSUPA.
Something to think about.
That being said, I generally get about 1.9mbps down, 1.9mbps up on HSUPA. Stock radio.

I average between 4.5mb up to 8mb depending on data traffic and my uploads average around 2.5mb
I think most of it just has to do w/ the coverage in your particular area.
I get the "H" icon a lot at home, but my speeds are usually < 1 mb as you can see:

The most recent amazingly fast ones are taken at my work.
I'm getting an average of 4.2 Mbps using the stock radio.
Can you change the radio when you're not rooted? Don't really know much about radios.

Network speeds are affected by much more than simply your radio version or ROM type. See my post above for explanation of the "H" icon in your taskbar for a little look into that.
You can flash your radio independent of your ROM, some people get better performance with other radios, but I've gotten consistent performance with my stock radio and a few different ROMs.

Yes, you must be rooted to flash new radios. Unless you're having network issues, and you're happy with your speeds (I hope you are at avg 4.2mbps) then there's no need to be flashing different radios.
Radio - 26.06.02.27_M
Running virtuous v1.0.1
I only get 350kbs-1.5mbs download and 800kbs-1.5mbs up. The upload isn't the problem. The best download I have ever gotten was 2.2mbs in my area (with the H or 3G+ symbol and 3-4 bars). I did get 3.5mbs download once, but that was on the other side of town.
Just to clarify, when I said 4.2 mbs was my average, I meant my average at the moment. I did 3 tests.
Although, my average overall is usually about 2.5-3 mbs which is still good enough for me. Just hate when I randomly get Edge out of nowhere.
Best speed I ever recorded was 5.37mbs late in the afternoon a month ago or so.

Man I thought I lived in a **** town because I only saw 6.5mbps max when our phones are capable of easy double digits. Especially when I see some people having screenies showing cell speeds of like 9 or 13mbps. I guess I have nothing to ***** about.
Although I have found I can do just about anything I really need my phone to do if I have atleast 1.5.
I only get like 5mbps downloaded and 2mbps uploaded. I really dont think that the 4g network isnt completely up yet but the speeds are okay with me.
Lately I have been experiencing some slow 3g speeds. At first I thought that 3g reception in my area was just not very fast, however I don't think that's the case anymore. For example, I did a speedtest and got 300kbps down and 400kbps up while a friend of mine standing right beside me (also on verizon and has a Droid X) got 1000kbps down and 500kbps up.
What could be causing slower 3g speeds? Any help would be great as slow speeds are very annoying. Also now he keeps insisting that his phone is vastly superior to the Dinc...

I have not tried flashing a new radio ever sense I first flashed 2.15.00.07.28. Is there another radio I should use or could reflashing that one help at all?
Noooo no no no no don't flash the radio again. That causes bricks, so I've heard. There are three newer radios than yours (9.01, 11.19, and 4.09, in that order), but there isn't any way to tell which one will work for your phone in your area except by trying them yourselves. But... Flashing radios is risky. You should always check your MD5 sum with the one provided from where you downloaded it. You can get them all from www.dougpiston.com
Sent from my Droid Incredible running CM7.0.3.
Only way to brick is to pull the battery when flashing the radio. Check md5, have a good charge and you'll be fine.

Ok if a new radio might help I guess ill try that.
The same friend mentioned that his rom included something that removed the data throttle. Obviously that could increase speeds... anything like that for the Dinc?
I don't know if it was just the natural variation in data speed but I got better speedtest results with the 4.08 radio. As far as throttling, if there is any throttling done its on Verizon's side and you can't do anything to your phone for it. If you were being throttled you would see an icon in your status bar and (should) receive notice from Verizon. The only people that would be throttled are (I think) the top 5% of data users so unless you use A LOT of data I wouldn't worry about it.

I was running speedtest.net app on both mine and my fiancée's DInc and noticed how much better my d/l speeds are while in wifi mode. I was at 10,000kb and she was only getting around 3,500.
Does anyone know why this would be? Why would the stock ROM not allow me to download at the top speed possible? Is it a CM7 thing or this just a fluke? Anyway I just found it interesting
Sent from my ADR6300 using XDA App
I run CM7 and have noticed slow speeds the last few months, but have chalked it up to network traffic. I am not a big data user, and when I run speedtest in the morning speeds are much more reasonable. I also ran a different speed test website, and it was considerably different. I don't know if the app is that accurate.
Through the different Sense ROM's and CM7 versions I've used I can say I get the same results.
CM7 has faster 3G transfer rates and WiFi. Don't know why
