Same place, same test - diferent results - EVO 4G Q&A, Help & Troubleshooting

Both rom with 4G (calkulin and UNleashed-Ultra_R2) but results difference is huge. Tested Koni rom and have great results just like with UNleashed-Ultra_R2.Why is that? (looks like calkulin 4G is 3G please prove me wrong) Flashed both rom several time back and fourth and here are my results. Just to add Calkulin its my favorite ROM, at least it was until now.

I am in the hinterlands so I do not know what 4G would be like, but I am skeptical it's not simply a result of traffic on your node.
If you are flashing back and forth, how much time was between tests? Even if that gap was limited to 3 or 4 minutes, it seems hard to compare without like devices next to each other.
How consistently was that spike produced?
Although it's over 3G, I produce fluctuations of 30 to 40 percent with the same device/ROM in back to back Speedtests.
I am fairly consistent over 3G comparing the stock ROM to SalvageMod 1.0.
I think the issue is generally Sprint.

Doesn't meter because at end I tried with 2 phones at same time and results are staying same. Calkulin give me almost same result on 3G and 4G, and that is same result I had on Unleashed with 3G. That should be enough. So to confirm:
Tried same phone
tried different phones same time
Both way results are same
Question is.. why are your results on both 3G and 4G while using Calkulin rom?

I believe you're having an isolated incident, no difference between my phone running v1.8 and my wife's stock, unrooted phone. Download/upload speeds are nearly identical with 3G and 4G.

Wifi w/ CM7

Since installing RC2 & after my wifi signal seems to be lower than it was. I can be right next to the access point & have full signal strength then just walk away 15 ft & it drops more than half. Any way to really calibrate or fine tune it?

Well, best you could do would be to re-flash RC2, or my better suggestion would be to flash to the latest nightly, as they incldue fixes for gps, wifi, and other things.
You do realize that a "bar" is not any type of unit of signal strength measurement? Basically cm7 uses different thresholds for number of "bars" displayed. The signal strength is the same.
I compared with a co-workers EVO and anothers G2 and their # of bars was 2x higher than mine. So if that is not indicative in CMod7 than that's fine. I just wanted to make sure that the wifi was still functioning correctly. I wish there was a wifi diagnostic I could run.
Yeah. Have the same problem on Nightlies 19 but if you say the strength is the same then I guess it isn't really a problem.

no i agree...whenever im on a sense rom or MIUI i have almost full signal and im 20-30ft away...but ever since ive been on CM7 i can be standing or sitting in the exact same place and i'll have one signal bar and sometimes it'll even lose almost all of it's signal for a few seconds...the only time its at full signal strength is when i am right next to it...i just assume it's something with CM7 that still has to be fixed...but i definitely notice a speed difference between 2 bars and one
As stated above, use the latest Nightly. Works fine for me. Especially considering I can pick up AP's on the opposite side of a commercial building.

[Reference] 4G speeds

I've always been curious how much 4G speeds vary from place to place. I travel a lot for work, but lets face it, Sprint coverage maps are pretty much a best case scenario or an Opium induced fantasy at best. Post your 4G speeds with a screen shot, (pics or it didn't happen), please no flaming. If you don't have 4G in your area, please don't troll! Hopefully Sprint will get you covered when lte rolls out.
Real simple, get speedtest.net. Check your 4g speeds.
Take at least 3 tests to show average.

4g? What's that?
Ha, ain't got 4g here.
Speeds vary. If I take them in the morning i get 9mbps and at night. In the afternoon 4g is kinda bad

+1 Seams as though network traffic is definitely lower at night. Varies by tower as well. Just a few miles up the road in Kansas City, I can get upwards of 10M with a weaker signal then I have at home.

never really use 4g unless i need to tether really badly. I usually stick to non 4g roms

FC14 Modem = big improvement

I have tried all previous modems for this phone, they all disconnected from 4g network a few times an hour when I'm in my apartment. I have been running FC14 for 3 days now and haven't had a single disconnect.
This link is from Calkulin:
http://www.buildarom.com/E4GT/Modems/E4GT_Modem_FC14.tar
Duly noted. I'll check this out.
i would get .30kb down and NEVER get a gps lock until i started using the fc series modems........now im getting 1.5mb down and an instantaneous gps lock!
Agreed. FC14 has been really good to me. Im going to try FC15 later today.

Can you use the fc 14 modem on gb as well?
I think you can just want to be sure.
yeah, I'm using a GB rom with it
FC14 was really that good? Dang, looks like I'll flash it now. lol

When changing ROMs I like to flash my modem while still in GB before ICS to just avoid any hassles and it seems to work fine in 2.3.x.
I can confirm better gps reception on fc14 modem vs el29. GPS locked in about 5 seconds vs the minute it used to take.

Yea it is. Auto brightness. No undervolt. Using Setcpu similar to Calks battery script, except I have mine running at 1.2ghz for 10% more. 1.2ghz (100-70%), 1ghz (69-35%), 800mhz (34-0%). And thats about it. Just used my phone regularly. I was on WIFI the entire time. Though, STILL VERY IMPRESSIVE. I use to hit 3-3 1/2 hrs on screen time with wifi on 100% of the time.

Depends on your area but my average speed is:
Upload: 1-2Mb
Download: 5-6Mb
It also changes depending on the rom you have if your rooted, for instance with serenity rom my speed is:
Upload: 3-5Mb
Download: 9-10Mb
Depends on your area, this is what I get around Columbia, sc

I am located in NYC, so most likely I would get awesome speed
Speed varies, even within like 10 feet.
Nyc should get good speed expect lite low 8 to high 20 average most likely 12

Check this to see if your area has been upgraded to hspa+42. If its not listed you're probably going to be on +21. (Maybe slower still in rural areas).
http://newsroom.t-mobile.com/articles/hspa42-fact-sheet
On +42 people seem to get on average 12-18Mbps downlink with peak speeds up to 28Mbps (fastest I remember seeing reported)
On +21 averages seem to be in the 4-9Mbps range with peaks up to 15Mbps.
Of course these are averages and peaks so ymmv. Check my modem thread sticky in the development area. Post 2 has a map where you can see if people in your area have reported their speeds.

Really depends on your coverage area. I sometimes get 25 down sometimes 9...upload is around 2
Sent from my SGH-T999 using xda app-developers app
im also getting dl speeds of 6-10 mbps, upload 1-3 mbps
Highest reported in the post your top data speed thread I have created is 29mb. But I think I've seen above 30 on youtube... its no LTE 40+ that I've seen at&t do but it can get the job done that's for sure.

Incredibly slow 3G data; is Sprint throttling me?

So, for the majority of last month I recall having absolute **** speeds on 3G ranging from 20 to 70 Kbps occasionally reaching to something like 120Kbps. This is in my normal coverage area where I can often get from 1100 to 1800 Kbps. I had thought that I might be getting throttled since I used a total of like 14GB of 3G last month. The new billing cycle started today and I'm still getting the same horrid speeds. What gives? I've already reflashed my ROM and modem without any benefit. Anyone else know what could be going on?

Sprint is the problem. LOL I'm not sure have you tried contacting Sprint? I'm jelly that you can even achieve 1200kbps.

Seriously? Who would stay with a carrier that would take 5 minutes just to load a picture? I'll be sure to call them later. For some reason that never crossed my mind.

I tried Sprint briefly years ago, sounds like they haven't improved much since then.
if not for the LTE in my area (san antonio) sprint would be unusable.
It sounds like 1X data speeds and not 3G, some of the stock roms display a 3G icon even when connected to 1X data. If you use the speedtest app
it will show a graph of the results, if the speed graph looks like it hits a ceiling around 100k,.it is probably connected to 1X data.
If you see multiple spikes in the graph well above 100k, it is probably a crappy connection/signal.
Same here. I'm on Virgin Mobile, but it's apart of Sprint too. It's been crappy for the past week.

I'm on Sprint. Get about 500 to 1000kbits on 3G in my area. I understand they're not great in all areas, but the price is good.

So. Uh. If that isn't the best speed test you've ever seen? I think Jellybro has the 1x indicator fix and the normal upload speeds seem to indicate I'm on 3G. Sprint dude just said to take it to a store. I guess I'll do that. Unless going back to complete stock might fox something. I'll try that next.
