[Q] 3G reception dropping very low intermittently?

A VZW macro-antenna was recently placed on the building across the street from where I work, and for the first week after I returned from Christmas vacation, I'd have a solid 3-4 bars all day long. Since doing more extensive ROM/kernel modifications to my phone, I notice that my reception will jump around a lot... 4 bars, 1 bar, 3 bars, 2 bars, 4 bars, 1 bar, etc.
Using a signal widget confirms that it does actually vary quite a bit... such as suddenly dropping from -86dmb to -106dbm, then bouncing back to -86 without the phone having been moved.
Has anyone else experienced anything like this or have any idea what might be causing it and what I could try to alleviate the issue? I suppose I could go back to the adrynalyn's 12/12 test kernel (the one that came with DJ05), but as I'm currently using both Voodoo lagfix and sound, I'd really rather not have to do all that.
Currently using Superclean 0.9, JT's 1/23 voodoo5 + lagfix + sound. Thanks in advance for any assistance!

I dont have exact DB measurements but I can tell you that just sitting at my desk at work my 3G connection speed varies from 1mbit to 10kbit in about 4 seconds sometimes. The network just dies. It slowly builds back up to 1mbit and then dies again. Pandora streaming is annoying.

edit: after 4th try of *228 option 2 i now am getting better signal and 1.8 down and .6 up....maybe verizon was having issues in my area and now they have it fixed...we shall see

I have had problems using that kernel (Superclean 0.9, JT's 1/23 voodoo5 + lagfix + sound.), with my cell signal dropping out entirely at random times.
Once I went back to the previous kernel I was using, everything was fine again.
How long have you been using your current kernel?

Im using adrynalyns latest i think ...with voodoo and voodoo sound fix...for about a week now....i've tried just about every kernel i could find but still had the same problem. *228 has done the trick so far......my signal is low but is constant....its no longer dropping to 2g at least.

I thought the 3g to 1x problems got fixed with DL09 (stock rom) but it still appears to be a problem when I get in a low coverage area. My friends HTC Eris with the same low coverage still maintains the 3g while my Fascinate starts to switch to 1x and won’t grab 3g until a reboot or at least 3 bars of coverage are present. I tried *228 several times with no luck. Any ideas?

Gps signal lost..often

So I have been taking a plethora of couple hour long trips lately and have had to use my gps..I've noticed they multiple times during the trip it looses gps signal for a minute..in downtown areas or not..anyone else having this issue?

Unfortunately, very common issue. It was supposedly fixed with DL09, however consistent threads complaining about it lead the rest of us to believe otherwise.

Weak. Oh well. I'll deal with it. Though it almost got me lost on the way to a damn important interview

Anyone else think EE03 modem sucks?

I have given this modem several chances and it has disappointed me everytime. I consistently get 300 kbs less at home on my Airave on 3G. Out of the house it stops downloading in the middle. Speed is up and down. I lose internet off and on. All on 3G. 3G icon sits there but no blue arrows flash. Sometimes I have to toggle airplane mode several times to get 3G going again.
The only good thing I have found is that I can connect to 4G in my living room consistenetly where the EC05 modem was hit or miss. So if you use 4G all the time this may be a good modem for you. for 3G...throw it out.

I had problems with 3G (dropping out and not coming back) and GPS lock when I first flashed the EE03 modem. Second time around GPS locked and I haven't had the dropped 3G issue since that first flash. Not sure what's up with that, you'd think the problems would be consistent. However, im prolly not the best gauge as I have Wifi everywhere I go. I use 3G sparingly. I haven't compared speeds between the two modems though.

Yeah, that's why I gave it the best test possible with an Airave. I get 1.8Mbs with EC05 and 1.5Mbs with the EE03.

3g signal and strength seems a little stronger for me but not by a whole lot. I've been running it without any issues.

3g drops constantly with ee03. Can't wait for a stable gingerbread!

EE03 speed up my connection quite a bit. No issues here, and paired with SRF 1.1.1, my phone is extremely fast.

I'm fine with it. Little difference

For those with EE03, does it write/change your Wimax settings. I changed a bunch of mine while using ED05, namely the min signal strength toconnect. Default was like -89 and I lowered mine to -94. Def able to connect more, but if it doesn't... u can just watch the bat guage spin. Just wondering if increased performance with the new modem may be due to tweaking the settings.
I had changed my 3G extensions... blanked them all out. They got set back to default while flashing a ROM. Never got a chance to evaluate a difference. Are the ports/proxies set up the same with EE03? Maybe try blanking the 4 entries and see if that helps.

No changes, just flashed the modem.

No way I love the ee03 modem. I used to have a lot of emails that I would send hang for the longest time. Haven't had a problem at all with ee03 modem. Also 3g speed is so much faster for me as well. Just my opinion.

Have you ever seen this behavior on eb13's and ec05's modem? I have and also dk28's modem. I have this pop up from time to time on various rom/modem combinations and I'm starting to think its some sort of RIL bug or 3g handshake bug, maybe even some sort of permissions bug (really I have no clue tho).
I see this happen from time to time. I'm in a spot that always has 3g, but what happens, it just sits there loading, all the while my 3g icon is dormant, doing nothing. Then out of the blue it goes to 1x and starts working, but only with 1x, then when its done loading whatever, it will bring 3g back and it may or may not repeat the same thing again when I try to pull data. Note; occasionally it will retain 3g, but be hexa slow.....1~10kbps slow.....ouch, that's slow.
That was why I spoke of a modem binge in some other threads. Originally I thought it was sprints network taking a dump in my hand(set). Now after seeing an evo getting 3g right next to me, while mine was stalling and eventually dropped to 1x and also trying every decent modem. I have to believe the problem is in my phone some place.
Only thing I have recently discovered to work is to fix permissions in rom manager, I don't use rom manager for anything, except fixing permissions. The only reason I even tried fixing permissions in rom manager, was after fixing permissions in cwm (3.0.0.6) my phone would (sometimes) get stuck in a boot loop and the only way to fix it would be to clear cache and dalvik cache or restore a backup in cwm. However this modem bug/issue still pops up from time to time, mostly when the phone has been sleeping for 10minutes or more.
I actually think the ee03 modem is pretty good. Just my problems are not.

i wouldnt know lol ive been stuck on dk28 since the usb ports on my laptop are broken

I'm unable to connect to GPS and I don't like how switching from WiFi to 3g necessitates me enabling airplane mode
Sent from my fully armed and operational epic battle station

@Epic4gee...Yeah, I got those symptoms but only going to the EE03 modem. Maybe it is a tower/modem issue for me. But the biggest thing is that it is slower on an Airave which should be the best connection I could get with a 30Mbs broadband connection. I could pass off the connection drops as Sprint but not the speed difference.

Yeah 3g sucked for me too

I'm calling malarchy on this thread since this morning I was getting 1.2 mbs/s on 3g, 7.45 mbs/s on 4g and 17.07 mbs/s on wifi with multiple attempts. I think like all devices thios varies by region, modem software and device hardware. It'll never hit that venn diagram where all 3 circles coexist at their highest points. I was probably in some mecca of coverage this morning.

Did you put the EC05 modem back on and test it in the same area? You will get about 200-300 kbs more in speed on 3G. I consistently tested this on the fastest connection possible, an Airave with Broadband 30Mbs connection. EC05 is faster, EE03 connects to 4G better in low signal areas.

I have 4g in my city, why would I ever use 3g unless I really had to? My 3g has always been jack unless in specific circumstances. I've actually noticed it to be zippier while lacking the download test results.

I see a major improvement in the signal with the ee03 modem. I live in portland, and went from 2-3 bounding bars to a steady 4. My 4g still disconnects in my apartment, but it is stronger than it was outside my building.

[POLL] EF02 vs EF10 modem

I know this has been discussed, but I wanted some statistics. Also, I plan on updating to the EF10 modem because I have heard better things about it, but I have been doing well on the EF02 modem. My concerns are if I switch to the EF10 modem and it's WORSE, then when I switch back to the EF02 modem it won't be as good as it was originally. I mean EF02 modem has been good to me, but if I can get something better, then I'd rather have that.
I am running Stock Deodexed EF02 ROM.
Also, I forget. How will I get rid of the annoying message when it asks me to update? And if I get rid of that message, will I still be able to go back to EF02 and vicea versa?
Thanks guys.

only using the EF02 modem because my wifi won't connect to my router when i'm using EF10. :/

They both crash a bunch. EF02 doesn't get bad though. When it's on fire, it's on fire.

When I originally flashed to the same ROM as you, sir; I flashed with EF02, but allowed the EF10 update, charged, got great signal, never missed a call, or a message (except when there was an apparent county wide data outage... >.>) and got superb battery life.
I have, however, switched back down to EF02 just for dev purposes, and have really enjoyed it. Everything seems to be reliable (as much as Sprint allows) and runs smooth, great reception etc etc... I have yet to fully test the battery, but if it comes close to EF10's 16 hours I got on heavy use, I will be happy. I got through a full 10 hour day with 50% charge left on light to medium use. So I am thinking that the battery life on EF02 is better.
Either way? Both beat EC05 into the ground... over... and over... and over, and then urinate on them and grow pretty EF Flowers.

Once you switch to EF10 and reboot it will do a check, hit cancel quick and you won't see this message again, same goes for when you switch back to EF02. I just installed EF10 again after someone mentioned this, and I love it atm (3hours no crash,same TWS as DK28 sofar in my work area in a warehouse...

Playing with both
At first I got notably higher speeds on EF10 (using the speedtest app several times), but then they leveled out to about what EF02 was showing before I changed. Upload speeds on EF10 were dreadful at first but then leveled out as well. I'll give it a shot for a few days & see how it works--admittedly, I didn't use EF02 for very long, so I don't really have anything to lose by going to EF10.

EF02 for me. First day I got speed of 1800 kbps on download and 600 kbps upload, but over the next couple days they went down a small margin.
EF10 didn't show so strong at first, so I jumped back to EF02. Only main issue is how spotty both can be at times. Never dealt with as many no signals as much with EC05.

My Impressions of EG22

First I'll start off by saying tonight was a really terrible night for me so if this comes off as venting so be it lol.
Samsung, you're getting there that's for sure. Scrolling, screen off/on is buttery smooth and things seem to be working better than I had expected.
With that being said, there is still work that needs to be done. It may just be my location, but with the EG22 modem I feel like I've been roaming more than usual. I flashed back to the EC05 modem just to see and it confirmed my suspicion: either my phone or my area just doesn't like the new modem very much.
Another key component is battery life, it's been pretty sub-par for me. At work I have terrible reception (no bars, even roaming) so I put the phone on airplane mode and the battery is still dropping pretty consistently, much faster than on any of the other leaks or Froyo. Must be a rogue process(es) eating it up, but I can't be sure unless I do some digging which I don't really feel like doing.
All in all it's definitely coming along nicely, but by no means is it phenomenal. But for the first time since DI18, I can honestly say that I feel Sammy is doing some stuff right. Keep it up, don't let us users down

My impressions of the modem/rom is they are faking things a little bit on the signal meter as I know the signal isn't that strong in those areas. And it's not like a software update just gives better signal.

I agree that it seems like I'm roaming more on EG22, but the modem doesn't seem to have any effect. For example, I ran the stock EG22 build for a while and noticed the roaming issue and weaker WiFi reception. Reverting to the the EC05 modem didn't seem to help these issues. One of the stores I work in has a WiFi router that I can access throughout the store on Froyo (EC05), but on GB (EF02/EG22), WiFi disconnects when I walk to the rear of the store. Doesn't seem to matter which modem I'm using at the time. I even flashed back to Froyo yesterday but left the EG22 modem installed. GPS, 3G, and WiFi were flawless all day everywhere I went. So it seems that there must me some code/instructions in the build itself that are more relevant than the modem firmware.
Another interesting tidbit is that there basically is no difference in EC05 and EG22 modems. Randy did a binary differencing to generate a patch between EC05 and EG22 and the patch file is 142 bytes, which is probably about enough to change the version name.

I have noticed since the first GB leak that the WiFi reception is horrible now compared to a stock Epic with FroYo.

Yes, it makes me wonder if they might have the power to the radios dialed back a bit intentionally to help them diagnose something possibly?

I have noticed the wifi bars being low, but it isn't effecting the speed at all. I consistently get 1.5mbps down/600kbps up when over 3g, and have seen 9mbps on 4g. Call quality seems good as well. As for battery drain? It might be a bit faster than I'm used too, but then again, I'm coming from SRF 1.2. If there are any issues with the TWLauncher, I don't notice them because I'm a LauncherPro user. Issues with the browser? I use Dolphin, so if there are any, again, I don't know. Overall though, this ROM is stable enough for daily use.
