[Q] Low service bars - Serendipity 7 - Captivate Q&A, Help & Troubleshooting

Hey sorry if I'm posting something that has already been talked about, I know I'm new. After I installed serendipity I have been having really bad reception (I had excellent service everywhere before). I'm with Rogers in Ontario, I've read that my phone may be looking for a faster/more powerful tower, and disregarding a closer slower one? Any way to fix these settings? I would prefer not to reflash haha.
Thanks for any help

Could always try a different modem [Modems] - (Froyo & Gingerbread) - WCDMA 850 enabled

Just found that the JK4 modem works best for me in my area. Anyone in southern Ontario should try http://forum.xda-developers.com/showthread.php?t=867309

good to know, i am using that rom too. you can try speedmod kernel also, for the modem, it needs to be i9000 compatible.
I have success with both firebird kernal and speedmod kernel with the kp1 modem and the jk4 modem. You could tries these modems and see if they work for you. Not every modem will work the same for every phone in any location. You will just have to keep trying them out until you find one that works for you
well about every modem ive tried. aka or rom. works. just the poor call quality or slow network speeds. i tried speedmod last night. no go on ji6. whats wierd is on cognition or the leaked 2.2 froyo they work perfect on ji6. no matter the kernel. which i tried speed mod. glitterballs .4. so ill go out and find an i9000 kernel.
I am running dill's 6.0 with kp1 modem, 2 days now heavy phone use talking, texting, browsing and downloading. Absolutely no connection issues with kp1 at all so far. No voice quality issues either.

hi everyone. I have a captivate. live in america. Well i have had slow network speeds with jk4 jk3. jl1 jl2 plus poor call quality on the other end. ect. but the stock jh7. and the froyo leaked ji6 modems kick ass where im at. it even relialably plays youtube while on on the edge network.
Ive come down to di11is roms are the fastest. smoothest and the BEST gps. no bugs. has any one tried that modem on those roms? ie 6.0 . well i use that modem on some other roms and i know you need a matching kernel. so i flashed kernel then modem. still boot loops. anyone found a combo that works? is there a voodoo sound/lagfix kernel that works with this rom/modem. on cognition 3.04 i used .v4 gb kernel/ji6. and worked great. just have much love for di11is roms

If you read around, the pattern for modems is location based. It seems some modems work better in areas that other modems bomb out. I am going to take a chance and say you are in Kentucky if I read your user name correctly. It is helpful to others when talking about the modem that works best for you to be a little more specific then "I live in America". America can mean many different countries. (unfortunately in todays world climate it really only means one place)
Sorry just a pet peeve of mine.
For me in central florida jl2 has been the best. I will test ji6 to see how it goes for me. Hopefully it will become a preferred modem.
Again I am not trying to be a troll, sorry if it sounds like it.

I don't understand that at all..... the only real difference is if the area covered is 850/1900 or 1900 only..... otherwise how can there be a difference?

I do not disagree with what you say. But reading around there are very similar findings in specific areas. I will look for the threads in the morning. Nyquil kicking in.
im auctually from indiana. sorry for putting up america. At first this modem stuff didnt make sense. How 5 different modems will have 5 bars but each one has different results. would be nice if it was like a pc. windows or linux or mac. where if the drivers installed they just work. Its just such a deal breaker when i get to work and the net is just slow even with 5 bars. (jl1 jl2. jk3 jk4) but with ji6 it works great. and speed test are wayy higher. am now checking out deviant roms. found i9000 with voodoo and ji6. hmm might be able to get di11is working with ji6 here in a minute!
well tried firebird 2.0. tried few other kernals no luck. i flashed kernal first. then modem. no luck. firebird says works will all modems. ive tried. both 959 vibrant ji6 and ucji6 cappy modem. same result. sends it to boot loop. its something easy. is it because its a i9000 based rom? cog 3.04 it works with all those kernals ive tried on dillis

not modem, "modem.bin" it is the file that controls the radios. the reason for changing it is either for frequency settings for your location. north america other than t-mobile uses 1900 and 850mhz some countries like austrailia and new zeland use the same. europe uses 900mhz instead of 850 and many of the roms ported to out phone have the european modes. for that reason we use the canadian bell and telus modem.bins for the i9000 roms.
also the captivate modem.bin versions dont have hsupa conectivity and the captivate roms are not compatable with i9000 modems, the bluetooth calling doesn't work in that combination. it is also recomended to match the kernel to the modem but i find that the chinese captivate i9088 modem and the telus t959d modem work better for me than any i9000 modem available.

Well sounds like we have an WM user. On Android they are modems and to be honest it is a best one for your area. I use jk4 in Alaska
actually never has a winmo device I have dell streak, first droid device.
but Im asking so I can flash the wife's cappy, she's complaining about signal strength, let me check what rom she has, I believe she has 500mhz speedmod kernel on a i9000 based rom.
I though I saw some HTC droid's , like Evo refer to modem as Radio

oh ok that makes sense. HTC use radios and not modems. just make sure that the rom fits the kernel and modem. it will be trial and error.
Not to be a stickler but doesn't this belong in the q4 -q1 modem thread?

Isn't zel a mod? He seemed alright with it's placement haha
It is like zelendel said it is mostly trial and error for your area but I would give JL2 and JK4 a try they have given me the best results JL2 better signal but JK4 almost the same signal but slightly better battery life for me anyway
I made some changes to build.prop to my Dell Streak on AT&T, based on a thread I found on xda, it seemed to boost my 3g speeds, will build.prop tweaks boost signal reception as well? possibly??
edit: nevermind, didnt find the tweaks in build.prop, or defualt.prop, are they somewhere else? or are they missing from build.prop?
the lines like ro.ril.gprs_class=12, etc.
and ro.ril.hsxpa=3, etc.
Dont forget the 3 new ones, kc1 and the 2 jp9 modems.

Question regarding Fasty 2.5 ROM Modem (Horrendous upload?)

I have a quick question, and this may be completely based on the crappy service in my area as I usually get around 2-3 bars. I absolutely LOVE this ROM, but I'm not sure if the problem here is in the ROM or just my service. I have read that non I-9000 ROM modems are generally capped around ~300kb/s upload, however it's showing my phone using HSDPA, so I'm a bit disappointed with the results of my speedtests. My friends have showed me SS's where they have speeds of ~1.5 mbps (with the same signal strength). Is this due to them using different ROMs or modems? Or is it just the bad coverage in my area? I'm grandfathered in the old AT&T unlimited data plan, so I used the phone a lot as a mobile AP so any suggestions how to increase the speed if possible would be greatly appreciated. I realize it won't be as good as a broadband connection, but 300kb/s upload seems a bit ridiculous.
Since I don't have the appropriate number of posts to embed, I'm attaching the screenshot if someone would be so kind as to take a look.
Thank you
Change Your Modem, The Jl3 and Jk4 are my personal favourites.

Fasty 2.5 uses kb1 modem, perhaps it's not good in your area.
If you liked Fasty 2.5, then i am sure you ll love Fasty II v2.0 it uses kh3 modem, try it. It might solve yourarea issue.
Flashing an i9000 rom should get you the higher upload speeds (Mosaic is pretty good). I went from 300 to 1000 upload.

[Q] Modems,optusAUS on CM9

trying to break this down so that i get my questions answered. here it goes
im running CM9 build 17 all stock. on the optus network in Australia. a bit south of Melbourne but it shouldn't really matter where i am as long at im near major civalisation right? i mean i could go anywhere in aus and get the same results for reception and calls as long as im near the towers?
im looking for a good modem for me to use on the network, i have been looking at the voodoo majick that is nexus s modems and dont want to go there, they look silly. no 2g sometimes and no one is realy testing them. there all getting half baked results. and who knows what problems they havent encounterd yet.
ive tryed a few modems including offical optus modems and they dont seam to be the best performers sometimes. bad batterylife or slower network switching or bad call quality. what bands should i be looking for. i see alot of people looking for 850 bands but i dont think optus uses that one. what networks do here anyway? i know telstra do.
links or information will help give us anything and everything. ie try this/read that so on. i want to be informed for the future as well as a good kick in the general direction of go do it yourself in that direction.
Look for siky_dude 's modem thread, get radio-cm-7-ics-SGS-XWJW1-signed.zip and radio-cm-7-ics-SGS-XXJW4-signed.zip, try them, and read the thread for more info. Also look for the Australian thread. Good luck. And search moar
