"Download Booster" that uses 4g and wifi simultaneously - Xperia Tablet Z Q&A, Help & Troubleshooting

Hey everybody. I'm thinking of buying this tablet but I first want to know if it can use wifi and 4g at the same time, like the Download Booster feature on recent Samsung phones. This is a big deal for me as my internet connection is very poor (wifi signal is fine so things stay connected but won't load) and I want to smooth things out by using a 4g SIM. I know that I could switch between wifi and 4g when the pages aren't loading, but I want it to happen seamlessly. Thanks

I'm not 100% sure, but it seems that feature is not implemeted in Sony ROM yet.

You can leave both of them on, and tablet would decide which one to use. However you can't mix them together like Samsung does, that'd need a special piece of software to do that, just as @Rootk1t mentioned

How is the multitasking on this phone can you talk to someone and browse the web at the same time.
If your WiFi or four g you can. 3g no. It's a limit of cdma. Not the phone.

Thanks I wanted to know that. I also have heard that you can do more than 2 things at once also is this true and if so how many things can you do at the same time.
The evo3d has n wireless on the 2.4ghz singal. And if you have a n router with that band its awsome. I have a n setup just for my 3d. And when I'm connected I can talk via Bluetooth check my email and respond. Then I can hold the home button and hop over to xda and check on the root progress then hit home and go to the app drawer and open up engadget to see what new. Then go back to my email and refresh and see any new ones sent. Then hang up the phone and opening up pa and turn some good music on. And it never slows down. I might add I keep a short cut to running service on my home screen to see what running and I kill apps like google maps,voice mail,Spiderman etc. But using this phone on wireless n is awsome. Also I keep my phone charger plugged in when I'm gonna be using it like this because wifi and Bluetooth turned on at the same time will drain the battery pretty quick. Well hope this helps.

Wake me up when someone decides to support 5ghz N. 2.4 is nice and all and but you'd really see a big difference at the higher frequency.

semi a limit of CDMA.. as soon as sprint turns on it its SVDO service instead of EVDO, our phone will be able to do it over 3g (supposedly), our evo and the shift both have the chipset to allow SVDO..

Don't know if you know but 2.4 can reach 300mbps. The main difference in the 2.4 and the 5ghz is how reliable the signal is at a further distance. But both top out at 300mbps
Edit also the 2.4 can suffer from more interference from microwaves and cell phones but nothing that the user should notice especially on a cell phone. The 5ghz is faster and more reliable but it also requires a higher power supply which is why most cellphones although n capable cant see a 5hz network. It would drain the battery in no time Imo. 2.4 for a cell phone is more than enough being that its still the most common used frequency. With today's routers netgear,links,belkin,cisco etc offering dual band you can have the best of both.So for now I say anything over 54mbps on a cellphone is nice. And with my netgear I reach speeds of 79mbps to 92mbps. Also the Motorola atrix is the only phone that supports the 5ghz signal and from what I read its not a big difference. If you mean you will notice a difference on desktops and laptops then yes I agree but on a cellphone I don't think it makes a huge impact. Hope this was useful.

srsly, does speed really mean a difference when talking about cell phones? I understand jumping from 3g to wifi or 4g, but faster wifi or 4g over a smartphone is it really a difference?

if you download large files it means a lot.. i dont do anything from a computer unless i have to anymore (at home, at work i dont have a choice).. so when i download roms, music, movies anything, the faster the better for me.. and it does provide an increase in browsing speed, and navigating between all of my apps that require data..

Well it depends on the user. Connect to a g signal and surf the internet on your phone and dl s few things. Now connect to a "n" signal and do the same. You will notice a great difference and probably wouldn't want to go back to g. Hope this helps.

Poor WiFi performance next to laptop

Last night I was looking for a video on youtube on my photon, and my wife was searching on our old laptop. Both were connected to our WiFi router, and we were sitting right next to each other. The laptop was MUCH faster than the photon, and the photon kept hanging in the middle of videos.
I'm pretty sure it was a wireless issue. I turned off WiFi and ran it on 3G, and it ran faster with no signal drops! I went back to WiFi and the performance dropped significantly.
Any suggestions for how to improve the WiFi performance? Would a newer router help? The 2300 is tried & true, and I've always like it. Does WiFi channel matter? Other ideas?
I'm not rooted, if that matters for any response.

What build version are you currently on? Have you flashed any of the updates or is the phone stock from Sprint?
I don't think a new router would help. My wifes nexus s 4g always has better signal strength than my photon when on wifi, I compared it to a friends Htc sensation connected to the same router and he had the better signal strength, and places where my evo 4g use to get a very weak signal but was still able to connect the photon won't connect at all.
Just some info to add to the OP....
I have a good router at home and a good one at work (different brands) and my WiFi is fast and smooth while at work but sometimes at home it is slow and chunky. Very sporadic at home for some reason and it never seemed to happen until after one of the updates.

I have the same issue after the last "update". It seems to lose the wi-fi connection and keeps any network from connecting. I have to turn the wifi off and wait for the 3G to connect or I won't get any mail. I can't figure out what changed, but it used to work perfectly. I'm contemplating rolling back to the first update.

I have installed all OTA updates to date.
Build No. 4.5.1A-1_SUN-154_6
Ok, I bit the bullet and used RSD to roll back to the earliest version of the code (I didn't lose any data or even the location of the widgets on my screen) and it totally fixed the WiFi issues I've been having. Plus the battery seems to last quite a bit longer. I thought that the latest update was a loser, this just proves it.
I came to the conclusion on my own that the photon doesn't like any mixed wifi signals; i had my 2.4ghz router running with mixed b/g/n for wireless and it didnt play nice. Once i changed it to n only it worked way better.......

Sorry to be so late responding. I've been away from the forum for awhile (been out slumming with the iPhone crowd trying to see what the panic was about).
1FF-sunfire-user-2.3.4-4.5.1A-1_SUN-154_5-CM-release-keys-signed-Sprint-US.sbf
is the one I used. I just accidentally applied the OTA update and the WIFI issues returned. Back to the drawing board. I guess I need to do the "no OTA update" hack.
EXACTLY! This has been happening to me now on TWO Phones! I can't say that it's been just my home router though. I took my phone into the sprint store, hooked up to their wifi and same problem... Right off the bat it didn't connect to the market.
This happens at home and is super frustrating. I will get to browse a couple pages/apps/zedge then nothing. I've even had it go retarded enough to pop up the 3G icon as well as the wifi signal indicator...? No up/down arrows showed in the 3G to indicate data transfer but I was just like WTF?
So now when I leave my house, out of range of wifi, my phone blows up with e-mails, apps I've had in queue, etc.
I've noticed these problems more with the most recent update but I didn't spend too much time browsing without it though. Maybe I'll get a new one from Sprint and just never apply the update.
**EDIT: Both times I've received one of these phones the only update I've done is the most recent one. I haven't bothered checking the software version they are coming with. Is it possible they're no longer putting out the first update and these aren't cumulative? Just a shot in the dark but maybe I needed that first update before the second to make things jive. It's unlikely they would put out updates in this manner but I'm grasping for straws here.

My experience is different. The phone connects and works great at the office but not so great at home. Both routers are set on mixed. Not sure what the difference is (besides the brand of router). I do know the one at home is handing out IPs but the one at work is not. The server handles that.
Not sure what else could make a difference.
Just got my third Photon from the sprint store and same issue. This one already had the 42.5.7 update installed on it but wifi has been flakey. I'm convinced that it's something in the software combined with the wifi we are using. The ridiculous thing is I have a motorola SBG 900 that I use for wireless at home so you would think they would be compatible. I really like the phone otherwise so I hope a new update is right around the corner.
Just went and bought a $160 modem/router combo and my phone has no issues at all with wireless now...
Three Photons in a week and a good chunk of cash later and I can use wifi at home. And now that I've finally had time to play with it I find out wifi tether only does ad hoc natively.
I wouldn't mind having my Evo Shift back.
I'm having the same problem. I updated to 198_6 as part of the testing group and at first had no problems with Wifi. Now when I am connected to wifi (both at work and at home) I can't send or receive text messages, download from the market, nada. As soon as I connect back to 4G everything works perfectly. I'm gonna roll back tonight to the previous update. BTW, I also updated my PRL to 51082 and that didn't seem to help.
Is the problem basically where wifi is connected to the router then stops going past that? Like you still have an ip but no data?
If so try turning off notifications for gmail or turning off the "notify once option". This seemed to help me lose my connection to where i had flip on/off the wifi radio.
Let me know how you fare with this.

Are you running any "turbo or super G" like modes set on the router? I remember reading on the motorola forums that these sometimes may cause issues - other things, router firmware update if applicable... do you have an airave device? If so, make sure the distance between that and the router are more than 5ft apart in distance.
Still, in your situation - streaming over the wifi shouldn't be an issue with bandwidth to keep in consideration, but realistically speaking - that should be better than 3g speeds for video playback.
These were some of the thing I had picked up from while troubleshooting an ongoing issue I am still having with my old d-link di-624 and photon getting stuck at "obtaining an IP address" on the official Motorola photon forums. In the latter situation, mine will connect if I reboot the router... my other tablets and laptops connect flawlessly on this.

Does any of the custom ROMs solve Network/WIFI issues

I know the custom ROMs have a few nice features and clean up some dead wood.
But do any absolutely Fix any of the network issues?
For the record I'm considering OMJ's or Flipz's.
Some background for my question if you interested.
This phone is really starting to suck (Stock Rooted only, no mods).
I really wanted to hold out for possible S-OFF to try any custom ROMs but the phone is becoming useless without doing something.
Last weekend I used my Wifes EVO 3D (my old phone with MeanROM ICS 2.2 on it).
I Tethered from West of Boston to Central NH (2 hr 20 min drive) with out a glitch.
Phone was running Navigation and WIFI Tethered the whole way.
Not one glitch. I've done it many times. My wifes former Touch Pro 2 and EVO 4G was also just as reliable.
Same trip this weekend with the EVO 4G LTE.
Laptop lost WIFI connection to EVO 4G LTE like 5 times.
Sometimes I could get it back by reconnecting or restarting WIFI Tether.
Other times I had to reboot phone, and other times I had to reboot the Laptop to get it back. It just flat out refused to see the phone any more. Even tried shutting WIFI off on laptop and phone, but no, PC or Phone required a reboot not always the same either.
It was also fairly slow and laggy. Just aweful.
When I leave my house with WIFI on, the EVO LTE phone stays connected to WIFI and gets no data until I shut WIFI off. It works fine if I leave work with WIFI on though.
I know there are patches to remove smartsync in several ROMs but the phone was not going to sleep during most of these issues (Had Nav running).
You would need a ROM where someone actually rewrote some code . That's probably not going to happen till source comes out

That might be true but certainly not always true.
And if it is "code" I must depend on that get fixed it's likely a driver and most developers on XDA don't do drivers.
And that "code" could also be on the Radio Side (where I suspect the real issues are) and that code is never released.
Doing things like enabling the 2nd Core full time (which is enabled on my EVEO 3D) might make things run more stable. I don't know.
Most "code" on my EVO 3D is "stock" it's just borrowed from different phones and some build.prop tweaks.

Just my experience : zero difference in connectivity issues (cellular or WiFi) . Previous 3d and OGEVO both had their issues but in the exact same locations I used them ( work WiFi home WiFi commute cellular) -this thing is just bad comparitively. Wireless N (100Mgps down from Cisco rtr) at office drops CONSTANTLY and even just running l navigation will drop out from suburbs to city ( Chicago ) . Go to Mexico this week and I was there in December and was stunned how well Telcel''s network operated ( very fast 3g no dropped calls - thank god work picks up the tab). New York and San Francisco the week after in which I am very familiar with how my service usually acts so ill have some controls to measure against. Very dissapointing so far LTE can't get here glfast enough- realize I veered slightly off topic but , no, I haven't seen any major difference other than great battery life on Vipers

Dude, honestly, u need to take your phone back and exchange it. Had the same problem with WiFi dropping constantly, about every 5 seconds. Would go to 3g then WiFi. Sometimes switching settings would help, tried rooting and did numerous roms, fixes, mods, but the problem was still there.
Well, I took my phone back bc I bricked the secure element somehow and my new phone has none of those issues. I believe it is a faulty receiver/radio. Trust me and take it back for a new one before your 30 days is up. U will thank me.

I'm in RI and kept my Evo og just for tethering. If you were satisfied with the 3d, then the lte will seem more effectual in fringe area reception. Though not as good as the OG in my particular area. The og bounces across a bay without issues. Did I just say sprint has shoddy coverage? Whoops. Didn't mean to.
What I'm getting to is that the risk of depending on htc unlock, vs new radios might be worth evaluating.

Thanks for the data point.
I did try calling Sprint and the tech said I need to shut WIFI off when I leave home and work. They were clueless. After I explained to them how it's supposed to work they said I need to have tech look at it.
Yeah I'm sure they can repeat the problems at will. Some days it's fine.
I don't get WIFI drop outs. Biggest problem is it won't let go of the WIFI when I leave home and that locks data up until I toggle the WIFI enable. Leaving work it's fine.
I have put a custom ROM on it now (flipz). And it's running better. But did have to switch it to 2.4Ghz only again. I do like some the custom ROM features and it allows be to better monitor Data (since it show 1x or 3x) and I can do full nandroid backup to compare changes.
However I did see the bouncey thing when you wake it goes to WIFI to 3G to WIFI again and that I believe is a sign of it struggling.
Then I looked into my Router for more settings to play with and learned Bluetooth can interfere with WIFI (i.e. there are settings for it in my router).
I'm 99% sure this is the problem (and may or may not be the phones fault).
This would explain why a "new" phone could fix an issue because each time you pair a bluetooth device it may choose a different channel. Some channels will conflict with WIFI more than others.
It may explain why some people have no issues too. Can depend on your bluetooth devices as well.

For grins I left Bluetooth off today and it has run flawless. It didn't get stuck on WIFI when I leave home and it always did.
I need to dig into how to check what channel bluetooth is paired on and how I can control what channel is uses.

I think you're onto something... If I leave the house and wifi sticks on, then I normally have to reboot phone before I can connect to wifi again. Simply toggling wifi off and on doesn't work.
So on a whim, I turned off bluetooth. Then turned wifi off and back on, and bam! Connected! Hmmmm....

Weird. I had opposite. Rooted, S-off and flashed MeanROM which really liked but bluetooth on one of my cars that was foolproof on stock became very hard to connect. Went back to stock and connects fine again. Miss the customization and may try again. Was a good exercise putting back to stock if ever need to return phone to Sprint.

[Q] Portable Hotspot/Android Tether limited connectivity

For some reason, when I tether my phone's Internet it works fine for a moment or a long time and then it switches to limited connectivity. No Internet connection on any of the connected devices, even if I reset the connection. Only restarting my phone seems to work.
Using stock Android 4.0.4 and the stock tether.
Has anybody else experienced this? Any solutions would be greatly appreciated.
Well, none of you bothered to reply to this, so I might as well. After I upgraded to 4.1.1 it seemed to work better, and it wouldn't turn off if I leave power saving off. However, the internet still randomly refuses to work on my laptop and only connects again if I restart the phone.

4G or 3G model? I have to turn LTE off because if it bounces around from LTE to 3G+ on my i9305T it tends to hang. I cant use wifi tether at all when CM10.1 when LTE is enabled, well I can use it but its very unstable. Try turning LTE off. If that's not the issue I'm sorry I can't help.

I don't really know because I don't have LTE at my location, the best reception I get is HSPDA+ which I heard is like 3.5G. I'm not really sure if my device is capable of 4G/LTE. It occasionally switches to E-GPRS when I'm not using the internet. But very rarely (like maybe once in 2 days), the internet just refuses to connect both in my phone and laptop eventhough the data indicator has the green and orange arrow on. When I restart it, it usually works fine. It's really confusing.

[Q] Mobile Hotspot only 3G

Has anyone tried to use verizons' mobile hotspot with this yet? Every time I have tested it out it reduces the signal from 4G to 3G and never returns to 4G until I deactivate the hotspot. Anyone know if this is a design in the phone or maybe something I am doing wrong?
I'm new to verizon like as of two days ago and Ive been with sprint. Does verizon make you pay an extra fee to use the tethering service like sprint because i can turn on the hotspot and connect to it and its says its using 3G but i dont get any internet service to my tablet.
To keep things relevent:

The way I understand it is if you can access the service then it is part of your plan. Which is nice so you dont accidentally use it and get charged a boat load. I just moved to a share everything plan and was told by a rep that mobile hotspot comes included, which seems to be true since I am able to use is, even if only on 3G.
At the same time, I am able to use the mobile hotspot through a Rezound on the same plan with 4G all day long. That is why I am curious if it is the phone limiting my connectivity while using hotspot.
I am currently testing the mobile hotspot as I am writing you. I figured I would try it out since I've not used it as of yet on my new DNA. 4G is working and intact. No downgrade to 3G, and everything is speedy as expected. I would check your signal strength or other possible issues you may have with reception, as if I understand things correctly, a 4G connection will degrade to 3G in bad connection areas. Maybe your signal strength isn't acceptable? Just a thought. Maybe someone here has a better understanding of the underlying operations of what your particular issue could be. Good luck...

I guess I figured out what my problem was. I just restarted my phone and tested again and it works perfectly. I dont know what its malfunction was but its all good now.
