Diff Roms Give Diff Signal Strength?? - EVO 4G General

Is this true or not? Ive been jumping from Swagged out, MIUI, to IC7 and it seems diff roms give diff signal strength...In one area where I hardly ever could even get 1X signal with the IC7 Rom I actually had a 1X signal...???

Aosp shows true signal strength. For example 2 bars on a aosp rom could show up as full bars on a sense rom

is that also true for WIFI?
I can attest to the fact that I too get better signal on Sense Roms then on ASOP roms...
However...have been testing evodeck's ICS (ASOP) rom...and I am getting some great signal that rival gingerbread's signal....so maybe it's not so much a sense vs ASOP problem with gingerbread...
just a thought
what I get from my laptop on evodeck ICS using wireless tether

True, if ur looking for sense base...ice cream sense v1.1 3g/4g is amazing...right along with everything else

Guys im not talking about how many bars it shows or any of that...Im saying when I was on one ROM I got ZERO signal (no service) but in that SAME area with a different ROM I got 1X and Even 3g?! Is that possible that diff ROM can give you a signal while another might not in a specific area????

Actually, AOSP Shows Data, Sense shows Signal

How many bars it has doesn't necessarily show how strong of a signal you are getting. Some ROMs take in to account the signal to noise ratio, signal strength, etc. so there will be some differences there.

It's been a minute since I've used my dinc because I have been using my Thunderbolt almost exclusively.. soooo I was wondering what you guys are using or think is the best combo. Radio I'm the most curious about!
Love being back on the dinc due to its nice and small size!!

My general advice; go with older stuff. With the exception of a few ROMs, the current crop appears to be some seriously jury rigged work that just barely works. I've yet to install ANY AOSP ROM that didn't end up self-destructing or failing from the first boot. I think WildStang ROMs are probably the best pieces of work currently out if stability and functionality are features that impress you.

All the Sense 3.0 ROMs run like molasses in January; SLOW as hell! 3D sure as hell isn't doing it any favors.
I'm using CM7 latest nightly, radio 11.x and tiny's incredikernel (10/8)
CM7 = It's quick, easily customization with android kitchen and with LP+ and custom dock it looks pretty snazzy
radio 11x = After trying all the radio's I find this one the most battery efficient, the GPS locks quick and data rate is excellent
( Note that differences between radio's are typically very small, I do believe this one is big enough to have me keep using it. Decide for yourself, everyone seems to have their own opinion on which is best )
tiny's incredikenel (10/8) = I actually just downloaded this one so not much of a review, but the quick charge and also the quick charge USB are big helps, not to mention custom voltages if you want to save a little bit more battery

Yes, that is the specific radio.
I have installed cm7.1 update and have tried every fix/ patch I can find in these forums to correct this horrible radio problem...I can't seem to get over two bars at any given spot. I have tried glazing new kernals, prl, radio, etc...what is the best combination to run cm7.1...any help with this would greatly. Be appreciated....thanks in advance....oh ya I was having problems with wireless tethering. Also but was able to fix that with placing a tether folder in root that was missing

The sense roms' signal bars are a little more generous than aosp. go to settings about phone and status and look at the dBm's for an accurate reading of signal strength.
On cm7 I usually stay between one and two bars, whereas on sense I would read up to four in the same areas, with the same dBm reading (no difference in actual signal strength).
I'm sitting at -94 to -97 dbm and 0asu....is that about normal?....I switched to a savage kernal the other day which seems to be helping other issues but radio is still an issue ...thanks for your help
sent from my Narly turbocharged EVO running CM7.1 with 22 lbs. of boost
what i'm trying to get across is that you don't have a radio issue. The same dBm will show more bars on a sense ROM than an aosp one.
If you'd like, flash a sense ROM and an aosp one. Then take an average in the same area over a period of time of what you're dBm's are. You shouldn't see much of a difference because roms have nothing to do with signal strength.
Edit: there us no 'normal' dBm number because there are so many variables to signal strength (distance from tower, humidity, elevation etc.). If you start to drop calls then you have a problem, if not, you're fine.
Gotcha....thanks for the insight!!!

Yeah you're not going to drop a call or get slow data from that, it is rather low though but nothing to worry about. Once it goes past 100 you should start to worry but again it'd still have to be significantly lower for all the bad stuff to start happening.
Besides all that, what makes you think this is a radio problem instead of just not-so-great coverage?
Just had some issues with wifi, calls, 3g/4g coverage , market connection( even on wifi)

[Q] wifi signal not strong cm7

anyone having issues with their wifi signal not being strong even if you are close to router?
not that big of an issue but it would be great to get it running up to par since i had better signals running the stock froyo.
might be that your internal wifi card got messed up happened to me on the iphone 3gs.
Works awesome for me.

I noticed it too, its one of the reasons I don't use cm7. I have to use wifi calling in my room and the signals sketchy.. its good enough to pick up on sense roms but the signal was rarely strong enough to connect on cm7. Maybe try a different kernel? MiUI is cm7 based and I always got good wifi with tdj's kernel, so maybe you wanna give it a shot.

Wifi speeds top out around 6Mbps?

I have a fairly fast cable service (high 30's/low 40's Mbps) and a decent wireless-N router. My Evo seems to hit a wall around 6Mbps, never higher. However, I've seen those on the forum who seem to get faster speeds then that.
I understand this is a relative limitation to the hardware and I'm not going to see the speeds I see on my laptop.
It would be interesting to see what others are getting for wifi speeds.
With my current DSL internet, 2mbsps down, one up.
With Comcast at someone else's house. 8900 and 10,000 with adfree on. Didn't know made much of a difference.

Try disabling mobile networks before turning on wifi it seems to help with my wifi speed although I've never tested my wifi speeds thru my evo cuz I don't use it much
We are legion, for we are many.
My work wifi can get speeds up to 100mbps on computers, and I normally see about 15-20mbps on the evo.
I get average of 7megs

With my uncle wifi he has comcast,the highest on sense roms I have reached 21Mbps down and 6.12Mbps up. but on miui the highest I've ever got was 14Mbps and like 3-4Mbps up.

I've wondered if it had to do with the fact I run AOSP roms and not sense.
It would be great if a dev could chime in and explain why there's a difference.

Yes aosp (cm7 or deck) is the problem with slow wifi speed. sitting right next to the router with cm7/deck my evo top out at 7 or 8 Mbps while sense rom (fresh latest) I get an average of 11 Mbps, my DSL top out at 12 Mbps. Also aosp rom suffer more from not only low signal but slow wifi speed when you move further away from room to room, where as sense does slow down but not as much as aosp rom. I love aosp and currently continue to use aosp because of it speed over sense base rom. In my test sense rom stutter/choppy while watching flash video via browser (stock or opera or dolphin) but aosp (cm7 or deck) run a lot smoother.
Kinda what I expected. Thanks for the explanation.
Have you tried 3GTurboCharger script that is located in the V6 SuperCharger thread, it includes wifi xer... something to consider...

I am currently running an AOSP ROM ( Deck 1.3 ) and with my TWC 30m down, 2m up cable modem I am getting 13 - 15m down and 2m up no matter where in the house I am. Even when I am outside in the yard and only showing one bar on the WiFi Manager widget.
I ** DID ** get slower speeds on the CM7 ROM. Usually in the 7 - 8m range.
I haven't tried the CM7 ROM since I upgraded the radios though. It might have made a difference.
On a Sense ROM (JTG-ICS-4.0.3 b4) I can get 20+m. But I do agree that my video streaming on the Sense ROM has been anything but nice. And that is on ANY of the Sense ROMs I have tried.

Rom with good wifi reception?

Using virtuous affinity at the moment and not liking the wifi speed at all (2 signals at a distance of 6 meters?)
I remember using one of the MIUI rom or sense rom which gave really good wifi connection, don't know what's the issue but my sister's I9001 is picking wifi at great distance and not mine + the speed is really slow...
DO you guys have a rom in mind which i can flash for better wifi connection?
EDIT: also some suggestions about runny vs bliss would be very appreciatd since i'm not a big sense user..
You can try RCMix3D, I'm always having 4 bars when near my router and a little less when moving away.
Maybe there is something wrong with the WiFi antenna.
The antenna is located in the cover of the battery.
Take out the cover and clean the metal contacts.
Put it back and see if it made a difference.
It's the 1st thing you should try.
If this doesn't help, check for a radio that matches your model, see also if a matching RIL is needed.
This most probably is a radio issue...flash the correct radio based on your current RIL..
Also think it's a radio problem. Flash the correct one and RILs and averything will be ok.
And for example, if you flash something like Virtuous Quattro or IceColdSandwitch, you may get low bars on the indicator, but it doesn't mean the signal is bad.
I'm running ARHD 6.3.2 with 12.65.60.29U_26.14.04.28_M Radio at the moment.I always have 3 to 4 bars wifi connection even when im in the room next to my office.
The Rom runs smooth and stable without having any problems at all.
Been using rcmix3d for the last couple of months and wifi reception has always been strong

Dont be fooled by the WIFI indicator bars, As i understand it AOSP based ROMs use a different algorithim to display the strength which results in an apparent lowering of the signal strength as long as it connects and works i play little or no attemtion to the bars.
Yes I would say it's a radio issue, unless it's posted as a bug in the ROM by other users. check the forums for the rom, otherwise, flash new radio WITH CORRESPONDING RIL!!

I agree with @ghostofcain, if your wifi is working fine, don't bother too much about the numbers of bars.
I had my best wifi experience with the AndroidRevolution HD 7.0.0 Rom.
maybe you really should bother about your Radio..

best way to see the signal strength is this:
*#*#4636#*#*
and then wifi information -> wifi status
there you've got the signal strength in dB wich is a bit more comparable than "i've got only two bars".
good tip using this test-number;
is the RSSI value the wifi signal strength ?
Yes. RSSI stands for Received Signal Strength Indication. Wikipedia has an article about it if you want more information.

Poor phone signal with Aosp ROMs

I'm having an issue that I don't understand and I'm hoping someone can help or at least explain what's going on. My phone carrier is MintSim which uses the T-Mobile network.
If I use OOS or any OOS based custom ROM I get a great phone signal--full bars in every room. If I transfer the sim to my Nexus 6P which is running Dirty Unicorns (an AOSP ROM) I get a great phone signal with full bars in every room. But if I flash an AOSP ROM on the OP5 my phone signal is poor to non existent. I have tried 3 different AOSP ROMs on the OP5 and I couldn't get a decent phone signal on any of them.
I've never run into an issue like this on any other phone. Can someone explain why this might be happening?
You shouldn't judge it by bars. Many manufacturers like oneplus and even samsung will make it look like you have full signal strength even though you don't. Roms usually report it correctly. Use a signal app and it should show the same signal strength in dBm

In Aosp I have two bars to none. I have also tried to make calls and was told the quality was poor. On top of that I'm using an Aosp ROM in my other phone and it shows the same signal strength as OOS. On all 3 Aosp ROMs I tried on the OP5 the signal was so unstable the signal bars never stayed the same for more than a few seconds.

I've never come across that issue on a previous phone. The only AOSP ROM I've gotten no complaints from people I called is Viper. The signal meter on the OP5 is really inaccurate on AOSP ROMs. I installed a signal reader app. It showed an excellent signal but I only had a couple bars according to the icon at the top of the screen.
did anybody able to figure this out, tried a lot of AOSP i think all of it, but signals just dropped out most of the time, followed flashing requirements on each ROM, went back to OOS stable 5.0.2 now 5.0.4 signals stick all the time, gps works perfect...just wanna know coz I still prefer AOSP esp the LOS 15.1.

It's been like that since OP3.
Will likely never be "fixed" at this point. Just get used to it, some recognized developpers declared it is only a "visual" issue.
I guess there is nothing to do about it...
I returned from LOS to OOS just because of that. It may be only visual, but would you ignore warnings on your cars engine? Bad signal means the phone tries harder to aquire it and it means more battery drain. I wouldnt really go with the statement its just a visual bug, especially on LOS where they have set the bar quite high in quality by themselves.
