bad wifi

hi. im using essential rom 1.7 and latest radio available, but where ewer i go wifi signal dont exeed 1 bar. in settings wifi is set to performance. what am i doing wrong? is there some other radio that i shoud use or what??

Not only WiFi is bad, the overall reception (GSM/GPRS/3G/HSDPA) with the TD2 is very bad!

maybe upgrade your radio? i would not say the TD2 is "very bad" but not as good as previous devices
im using 4.47.25.21 and its alot better,

Wifi of my device working fine. In my house if I stay in the room where is the router wifi I have four bars of signal, three or two bars in the others rooms depending on distance from router. The time to fix is always a few seconds.
For data/voice connection I set the band to GSM net, and not to 3G, because in this way I have a better duration for battery and a good costant reception. Furthermore, there is no excessive reduction of the speed of data connection.

My radio is 3.43.25.19 (ROM 1.39.404.4 NLD). I don't want to loose my warranty by installing unsupported ROM's or radio's.

[GSM/3G] Question to data connection

Hello,
I am owning a HD2 since 2 days now (and love it) and have a question about data connections. Maybe you guys can tell me more or help me. If you think this should be placed somewhere else, feel free to transfer it to the right category
I changed connection to gsm because 3g/hsdpa can drain battery life hard and i cannot charge it at all places...
Now, if I am using Google Maps or refresh the weather (to it on my own, not automatically) the Phone uses GPRS, right? Dont know much about this, it is my first phone (also windows mobile phone) which I am using with a "internet flatrate"... But I know with 3G it would be all faster...
My problem is that I dont want to change the settings everytime I want to use something which needs a better data connection like gmaps or surfing in web... So is there a program which I can setup for specific programs and functions (gmaps^^, browsing and so on) and which automatically changes to the better connection? And after closing the program it automatically changes back to the normal GSM connection?
I searched a little bit around but doesn't found anything like this.
I just want to save battery life if I am not using the phone (like I am sleeping or when it is just in the bag) because than it doesn't need a good connection...
I just found something called Bandswitch... Is this what i mean?
I hope you understood now what I am wanting. And just sorry if there are some mistakes in the text. I am just trying to improve my english knowledge every day
Greetz from germany, love your board!
best regards

AFAIK, if the connection is idle, battery drain doesn't change much between EDGE and 3G.
It's when you actually use the connection that the battery drain wil go higher.
When I'm connected all day long on MSN, with nothing else really using data, I don't see a difference when I'm on EDGE or 3G.
If I'm browsing a lot, then yes 3G drains more - but that's simply because as the connection is faster, I end transferring more data than I would on EDGE. For the same mount it doesn't matter much.

Thank you very much, will give it a try... Seems that this is what i want

HSDPA Nexus One users (tips, battery optimisation & stats, signal, etc..)

Hi,
I'm starting this thread to collect informations about using the N1 on a HSDPA network. Over the next weeks I'll be posting stats and infos about my experience on a HSDPA network.
*-----------------------------------------------------*
Tips
*-----------------------------------------------------*
(reserved)
*-----------------------------------------------------*
Battery optimization
*-----------------------------------------------------*
HSDPA seems to be very hard on the battery, and to get the most of your N1 there will be some sacrifice.
What COULD help:
- Dial *#*#4636#*#* and set the phone to "WCDMA Only" in the phone informations.
- Try the app called "battery refresh" on the android store. It will discharge your phone. Then boot into recovery and wipe your battery stats.
- Install setCPU from the android store (1$) and force it to 245/576 while the phone is standby/sleep (thanks djmcnz)
- there's an app on the appstore called JuiceDefender that allow you to disable APN based on time or your location.
What WILL help
- disable sync (push). This have a MAJOR impact on HSDPA network
- and obliviously set brightness to auto or lowest acceptable value.
*-----------------------------------------------------*
Signal optimization
*-----------------------------------------------------*
So far I've tried two different radio rom, and the older 4.03.00.21_2 seem to offer better signal. So you could try using that one.
*-----------------------------------------------------*
Bandwith optimization
*-----------------------------------------------------*
- If you have a rooted N1, you could try in "spare parts" the hotweiss's Radio mod (in miscellaneous). In my case, there's not difference but still could be worth a try.
*-----------------------------------------------------*
N.B. : Fellow canadians, if you are on Bell or Telus with your N1, your are on a HSDPA network.

You could try JuiceDefender, I think that app does exactly that.

I seem to get alot of network connection errors from market, to internet, and some games that use internet.
I noticed my signal is usally full bars but switches alot between 3G and H (HSDPA)
Are my connections errors due to the switching of 3G and H much like some people have issues with EDGE and 3G switching back and forth in certain spots?
Also that *#*#4636#*#* didn't work. EDIT: nevermind, needs to be done on the stock dialer.
I set my network from WCDMA prefered to WCDMA only. See how that works. EDIT: Still switches from 3G to HSDPA...

I believe this is normal behavior. The 'WCDMA only' option disables EDGE network connections so that you only use the 3G/HSDPA.
Cheers

I hope there is a bug on the N1 radios..Cause I can't last 20hrs with 1hr worth of calls..and small use of internet. Yet other people saying they easily go pass 30hrs with heavy use...liars..

I can still get though a full day, business and pleasure on a single charge using HSDPA, WiFi and making calls... lots of calls.
In an average (16h) day I will be connected via 3G for about 10 of those and WiFi for the remaining six. I make about 180 mins of calls a day, 20% of those using the speaker, I have a feed reader with 20 feeds that update constantly, I listen to music to and form work (20mins + 20mins), I might play a game or two and I often read xda and/or download during the day. Brightness at about 55% fixed.
I charge my phone overnight, every night (have been doing this since my original RAZR anyway).
I have never, ever run out of battery during a given day.
Setting the CPU to min in standby is not a good idea - it needs some headroom to actually complete background tasks and 245 is too low IMHO and will be counter-productive. I suggest 245/576.
If your usage is much above mine then I'm not sure how many marginal tips will be needed before it makes a meaningful difference...

I got these errors on T-Mobile as well - since moving over to AT&T with the AT&T version they have completely disappeared.

Well I'm not sure but on mine it switch from 3G to H only when I fetch data. Else it stays on 3G.

Testing Juice Defender now. So far it's an incredible solution to battery drain, if it does what it claims. Will post findings this weekend.

Yep I'm getting the same results here. Juice Defender is the most effective thing I've tried so far. I'll collecting stats about it right now will post later.

I don't know what SL4 is.
But a day is absolutely normal for a phone with HSPA enabled and activsync connection turned on all the time.

1 day with only
winMO
3G off
sound n vibes off
no panels slideshow whatsoever
and u say 1 day is normal

What is relevant on the consumption side is 3G/push email/data exchange and (obviously) apps stuck @100%.
Everything else will not change greatly the battery performance

everything is set to power savings whatever i could find here on xda forums and few tricks up my sleeve
ohhh 1day is when my phone is just turned on no calls made/recieved screen in
standby and full gsm signal

I get almost 30 hours 3g,calls (4h) without charging,no majour mods done,upgraded to latest firmware and sd card fix.
THERE IS something wrong there,if you dont talk or play with the phone it (airplane mode) it should last 2 nights,mine did so.

Not necessarily.
The battery performance is strongly depended on the network conditions.
And this not means just 3G v.s 2G, or good/bad reception conditions.
There are many other variables: the 3G type (plain UMTS, HSDPA 1.8/3.6/7.2/more, HSUPA and so on), the 2G type (plain GSM, the number of GPRS timeslots enabled, the coding scheme used, the presence of EDGE and it's different revisions) and so on.
This is still not enough, you have to consider if your GSM network is on 900 or 1800 band, and you have to take in account different performances if the BTS (or nodeb) are built by one producer rather than another, and its firmware revision.
All in all you can compare the performance only if you are living in the same place and you are using the same provider.
Just for example, my Milestone (with it's intitial FW) was lasting in about 6h if used on a Vodafone network (optimal reception, high speed network), but was lasting in more than 24h if used on the Three network (average reception, older HSDPA protocol).
Same as above, years ago, my P800 (a 2G only phone) was lasting in 3/4 days with Vodafone, a mere day with Wind

battery issue is solved but im curious what is that module SL4
because thats the only thing they changed (reset) while my x2 was on service

How did you solve the battery issue? And what's the battery times now?

i sent it to service and they
tested the battery ---> batt ok
reset module SL4 (still dunno what that is)

Why is my Battery Life Better with WiFi on?

For some reason no matter what build, radio or rom I use BatteryMinder tells me that I will get better life with wifi on vs wifi being off. (check jpegs in attachment)
If i turn mobile data off too I get better battery life as well.
Why is the Mobile network killing my battery?

Hm. Could the email checking be doing it? I would decrease the frequency of that. The processor might be ramping up during some parts of the email checking routine. It's also possible that your WiFi service makes the operation quicker. Negotiating a cellular data connection takes some overhead. Ask a radio expert...
Sent from my HTC HD2 using XDA App

Are you in an area that has poor reception? That can drain the battery pretty quickly. The phone is constantly trying to reconnect to the network.
