First of all, bumping is against the rules, post #2 was a bump..
Now to your problem, has you area changed, what is the network mode? U, E, G, G+, 3G, H, H+, 4G? You need to supply us with info, otherwise we can't help..
I'd say you've just reached an area, where the network mode is different. If not, then you have changed the modem, because those are the two things making out your data/speed
If you are using Wi-Fi, it may just be a coinsidant, but maybe you provider is doing something to the DSL and your connection is therefore quite rubbish..
If that is also not the case, maybe your device is underclocked a bit too much
Hope I could help!

It is modem related. Under clocking has nothing to do with it at all.

Underclocking has somewhat to do with it.
The more the processing power - The faster things load - Including Data from external servers (The faster the download and processing is)
If however there is not as much processing power to use, everything is a bit slower, and that's why you can't hook up Windows 95/98/99/NT PC to a DSL which as a higher downstream than 3.000 kb/s, it just can't use the power that's there
That's why I wrote, that he may have underclocked too far

[Q] Best modem for India ??

Hi everybody...
Can somebody tell me which is the best modem for India in terms of battery usage??
I have already many modems like lph lps lp9 etc etc... but no use.....
I use XXLPS.. That's great.. If you want really good coverage try nelp3.. But that's not to battery efficient..
I tried that.. Bt it was also very hungry.. 40% battery drop overnight with no wakelocks or othr usage

I know this probably doesn't help much but try a few different ones and see how your signal changes. Maybe use each one for a day and determine battery drain, network and cellular signal. It varies depending on carrier, location, etc. so you need to try them out and cannot rely on someone else's best option.

I'm glad you posted in a thread instead of starting one, but with modems you need to try multiple ones to get the correct one. My modem may have better battery life and signal, but worse GPS, or vice versa. Just try different ones, no one can suggest one for you.

Hsdpa/3g switching issues

First off phone is stock and un rooted.
My issue is that the phone will switch to 3g or E so much and then often not switch to H when I use an app requiring Internet so the app won't load anything. Anyone else have these issues or is there a fix? I'm in Australia btw.

If your phone is unrooted, there are limited things you can do to solve it. If it is rooted, you can actually try to flash different modems for your phone and see which one works best for you or just find out from this forum what modem is best for your carrier.

Sorry, I have looked around and you can actually flash modem through Odin if your phone is unrooted.
Oh really?? Thanks for letting me know, I haven't messed with flashing before so I doubt I will now haha i might wait for official updates...

Most official modems for my region are terrible, I'll bet your's aren't better. Asian modems have a far greater stability, especially the DXLF3 modem.
You can't do anything wrong when flashing a modem. Just get Odin, head to the modem collection thread, pick your modem and flash away.

Sounds like antenna ping-pong. Basically that means that your carrier keeps moving you from one antenna to the other.
Alternatively, check if you have any Proxy configured in the APN settings as slow proxies can cause the same issue: go to Settings->More->Mobile network->Access point names, choose the one reading 'internet' (or something like that)
Check if any Proxy server IP is filled in. If yes, write it down and delete it from the profile. If Internet doesn't work, reconfigure it.
If it's better, congrats
Oh really! I didn't realise the Asian modems would work well in Australia thought they would be specific to region, obviously not! I will try the flash if nothing else works..
I checked in the settings like u asked but there is nothing under proxy? Should here be an ip is that the possible problem?

Wcdma only still switches between 3g and H, trying it now. So it wouldn't make a difference would it?

there is still difference in term of speed between 3g and H. if you want consistent H+, change modem to BWLE5, if you not in LFB based rom.

with this modem, your phone will go straight from 3g to H+, it doesn't even know H anymore. lol. try it to feel the drain on your own.
I had the same problem with lfb modem on stock lfb rom. I fixed it by flashing lf2 modem.
Try it. If it doesn't work flash back the modem you had before.

LF2 is older than LFB. Are you sure voice calls still work?
I still recommend DXLF3 modem ^^

Hi!
I think you should flash another modem, Modem/Radio/Baseband is all the same thing and can be seen by going to Settings - About Phone - Baseband. It's basically a driver which receives and sends Mobile Network signals as well as handling switching between GPRS, 3G, HSDPA etc..
anyway, here is the collection of modems for our s2
also, remember that Usually just flashing and then using the same modem for 3-5 days should tell you how well it performs in your are and with you Mobile Network operator. Please remember that it takes around 2-3 days for a Modem to "settle" and achieve optimum performance, so don't judge how good a Modem is straight after flashing. That's where a lot of people fail when asserting battery drain.
on the sidenote, here is a youtube link on how to flash a modem:

Good modem for better battery life?

Someone can recommend to me for a good modem to my sgs 2 for battery life?
I have a problem that when my 3g is on, my battery life going down very fast. And when i turn the 3g off is very good.
My rom is wanamlite 12.2 4.0.3
Kernel siyha 4.1.4
Modem xxki3
Sent from my GT-I9100 using xda app-developers app
With LQ6 modem, it's exactly the same issue.
Two ways to find a modem that will work well for you:-
a) Find someone in the same country who uses the same carrier as you & ask them which modem they use, and try that modem in the first instance.
b) Get a bunch of modems (lots of links to CWM flashable modems on XDA) & try as many as you need to until you find one that works well for you.
You mean xxlq6?

Sent from my GT-I9100 using xda app-developers app
I am using the xxlq6 modem. The signal is great everywhere, and when it's working in 3g, the consumption is not excessive. The battery lasts me 18/19 hours mixed between wi-fi and 3g, with 3/3:30 hours of screen and use more than normal. In any case I advise you to try several and see which modem is best for you. I tried several before I get to that modem.
See 3G will eat battery.. Its a fact.. Dont ask which modem u should use... Try urself... And see which suits u and your needs...
Peace

Modems are location dependent. Also keep in mind that they are like ROMs and kernels in that you have to give them three to four battery cycles for them to settle down for you to notice a difference.

Some people use different models with their ROMs, best idea would be to flash the stock modem
The only thing I've noticed regarding download speeds is that no matter how fast my data connection is, Google Play will only download at 200kb/s as if its being throttled by google. Wifi isn't an issue. Anyways, I get good data speeds in using the ELKC modem but I have no idea what Three network your on
