[Q] Hotspot ON turns wifi OFF

I'm still new to smartphones/Androids...
After experimenting with the lastest update, it appears to me that turning on the hotspot option automatically turns off WiFi reception, and vice versa. If I'm wrong about that, please let me know.
Otherwise, I was a surprised and a little disappointed at that, since I can think of several instances in which it would be very useful to establish a wireless connection to the G2, and then re-serve that out as a hotspot.
I'm wondering if it's a hardware, legal, software, or simple greed reason that prevented TMO from making that option available?

Yes the hotspot feature doesnt serve as a repeater of sorts for wifi, it simply turns your 3G 4G signal to wifi. Imagine if you could do that though. You could share your wifi to yourself and somebody on another device could make a wifi call through your wifi, being repeated through your router. Clearly this would cause a glitch in the time/space continuum.

Are you for real? To create the hotspot you're using your wireless card, the same one you'd normally be using to connect to wifi. Greed has little to do with this short of the phone only having a single wireless card. But no worries, laptops can't do this, either, unless they have a second wireless card.

It's a hardware limitation. The wifi chip can only do one thing at a time: either connect to an existing wireless network as a client, or serve it's own internet. Not both.

Got it. Thank you!

first id like to say lol to the time space joke
next... why on earth would u even want to get a wifi signal from ur g2... and then broadcast the signal you get from the wifi? why not just connect whatever your gonna connect to the g2 straight to the source..?

If you are on an airplane using Wifi (which is paid, and usually cheaper from a phone than from a laptop), and someone you want to broadcast that Wifi signal to your laptop and a partner's laptop --- thus not paying twice. It could be useful then.
You can do one laptop with wired tether, but not two or more.

Well, I know now that re-serving/repeating a wifi signal is a physical impossibility with the G2; however, to answer your question, there are several instances where such a capability would be useful:
1. Our company's wireless network is pretty secure. We do also have a server for guest access but the password changes daily. So, if a vendor or other person drops by and wants to show me a demo or catalog that's on-line, I have to hunt down a tech guy who knows today's password. That's been a bit of a time-waste to me in the past.
2. I'm on the road with a few colleagues. I get my hotel room's wireless access set up but I sometimes have to fiddle with my other various wireless devices to get them to work and a colleague might bring a laptop over to my room if we want to work on something. It's not unusual these days for road warriors to take a wireless router with them just for these circumstances.
3. I'm at the airport with a couple colleagues and we're all working. If we all need to get on-line, we each have to buy an hour's access (which never, ever gets fully used) at $10 a pop.
4. I'm at some research facility or client's and I manage to get the wireless key for their network. But, while I'm there, other colleagues drift in and out and it's always another mad dash for them to find the sacred piece of paper with the key.
Now, there are various ways to solve all of the above (and all of them are real-world experiences), but by in each case the easiest and most economical would be for me to re-serve a wireless signal and give my key to my vendors/associates, if the G2 actually had that capability. I know it doesn't and can't now.
Still love it, though.

There's nothing wrong that mobile hotspot and wifi can't co-exist (one is server and another is client).
Same thing happens on my nexus one.

dude seriously

Dude seriously... its called an ad-hoc network... you tether your phone to your computer and then broadcast an ad-hoc network from your computer and there you go... I've used this for counter-strike lan games with 8 players before on the g1 and the moto cliq and my g2... goggle how to set up ad-hoc

hi, i just want to know if is there any solution to use Tethering (on Froyo) like a wifi repeater? can i do it? thanks
SOrry for bad english

Networking issues and a gs3

Ok so I am having some issues with my home network. Ill give you a little backround first, I have 2 wireless routers with the same ssid an password. My laptop jumps back and forth but my gs3 will only use the second router if I turn the wifi on when I am closer to that router. Once it jumps to the primary router it will never jump back, I have to manually turn wifi off and back on. I was just wondering if anyone has any ideas.
By the way router 1 is a e3200 with stock firmware and router 2 is a e1000 with dd-wrt firmware and they are connected by ethernet it is not a repeater.
The gs3 does it on all roms aosp & touchwiz. In fact all my android devices do the same thing, nook color, captivate, and backflip.
Any help would be appreciated, thank you in advance.

Ok so I played with my routers a little bit more and I bumped up the TX power on router 2. It's now back to stock, and since I never drop off that router now it won't switch to router 1 anymore. Does anyone have any ideas? Router 1 is the only one that is a dhcp server.

Are you looking for your phone to jump to the strongest signal? I use Best Wifi (https://play.google.com/store/apps/...stwifi&feature=nav_result#?t=W251bGwsMSwyLDNd) on my tablet to jump around my three access points. It doesn't seem to use a lot of resources. Strangely, my galaxy S3 seems to do a good job on its own finding the strongest signal.

WiFi speedtest on 30mbps internet

SPH-L710 (Sprint Official Stock Firmware Android 4.1.1) Rooted
I have 30mbps down and 2mbps internet package
im getting between 16mbps and 20mbps down and 2mbps to 3mbps up.
my laptop with built-in wireless card gets pretty much the same but when i use my usb wifi adapter (linksys in 2.4ghz mode) it gets 30mbps down and close to the same upload.
my router is a belkin n300 share with stock belkin firmware
so i know the router can do 30mbps over wifi as my linksys usb wifi adapter proves that.
just wondering why my laptop AND GS3 only get about 20mbps consistantly over wifi....
anyone do a test on their S3 over "WIFI" and see what they get or tell me what is wrong with my laptop and s3?
the router can not do 5ghz it is only capeable of 2.4ghz and b/g/n with 20mhz/40mhz bandwith
when i use that linksys usb wifi adapter its really working good but im surprised the GS3 is not, the laptop i could even understand getting the 20mbps (wireless-n 1030 built-in)
it dont seem like any setting i make really changes the speed for the laptop or the phone
suggestions would be great

yep
i pick the servers with speedtest app
im picking the same exact server i get 30mpbs with my linksys usb adapter
just wanted to note:
when using iPerf (only checking b/w over the lan) i get about 10mbps from s3 to laptop wireless n 1030 buitlin
when hooking laptop straight to router with lan cord and run iperf i get the same 20mbps on the s3
there is something wrong with the wifi in the S3 i believe

how about someone here verify this is a problem i found
tell me what you get. im sure you are gonna check if you have a fast connection to the internet over wifi

ask someone to do a speed test over wifi and no one wants to take the time to do it?
takes a few mins

Nope my laptop and gs3 get the same speeds. In also have 30mbps down and 5 upload

The USB WiFi adapter are far more advanced an faster than that of a phone or laptop its not a modem issue or device issue its just simply the WiFi adapters inside our devices i have a similar issue where i have a 35mbs plan and i only got around 15-20mbs i upgraded my router and now i nearly achieve my 35mbs mark but no matter what router you get if you use Ethernet or a USB WiFi card the internet will be faster because generally computers interpret internet faster over a hard connection vs a wireless connection where u still loose around 5-10mbs the only possible solution is maybe invest in a different router with the option to direct more bandwidth via WiFi or change your WiFi broadcast frequency to only one type or frequency weather it be 801.11n or 802.11g or 802.11b choose ONE that is fastest not all 3 or which ever you have because that generally slows your internet by great amounts as well

why exactly do the phone (gs3 in this case) and the laptop (built-in intel wireless-n 1030) get the same speeds?
with wireless-n (even at 2,4) single antenna it should get close to 150mbps (theorectical)
wireless G = 54mbps in actuality it is around 20mbps which is what im getting and yep i checked both the laptop and the gs3 show as wireless n connections
you made an interesting point about putting the router in a single mode like "N" and i have tried that but both the laptop and the phone will not connect unless i put the router in b/g/n mode
the linksys usb adapter will connect ok with the router in wireless "N" mode
i am running latest belkin firmware for my f7d3302 router

Because its a wireless signal most devices interpret signals much better through Ethernet or USB just because it cant capture the signal fast enough and long enough to keep it stable enough to stay at the same speed the router is broadcasting at sure enough the router is broadcasting at a stable speed but the device wont capture it fast enough the only solution i found is what i mentioned to either get a router which makes a more stronger secure signal or broadcast at only one frequency and the s3 should capture N maybe try changing from 2.4 to 5.0 and try N again otherwise there might be a hardware issue because i use my router at 2.4 with 801.11n on channel 10 and my internet is almost as fast as Ethernet and far longer range

Or maybe your laptop and phone aren't setup properly to register this type of signal i know i had to call Acer to get my laptop to register a N signal so might want to play around with your wireless settings

was able to put router in wireless n mode only (2.4ghz) by enabling "802.11e/WMM QoS"
now laptop with built-in nic and s3 can both connect at wireless n only
the laptop speed did jump up to what the hard wire ethernet cable AND linksys usb wifi are getting
they are all getting 28mbps (within a 1mbps deviation)
the phone is still stuck at 18-22mbps.
daniel4653
so the phone can actually get over 22mbps in "WIFI" mode?
are you on 5ghz N or 2.4ghz N?
would like to add
iperf from the phone to the laptop (builtin nic) is now getting 25mbps in multiple runs
this is on the local lan only in wireless N mode (2.4ghz) with 20/40 enabled in router
so this is a big improvement over the 7-10mbps i was getting earlier but the wifi connected to net is still 20mbps

With phones there is a bigger difference because they're might be many factors like the modem the type of WiFi chip the size of the chip range and capability also what ROM your running just too much that might vary but on my phone on average i get around 20mbs it seems to me there's a 10mbs variation because at work we have a 100mbs connection and i get around 85mbs i believe the s3 maxes out at 100 but to reach that you have to have some fast internet and either a gaming router or a business router

on wireless n (2.4ghz) it should connect the "link speed" at 150mbps
when its at 150mbps this indicates "Channel Bonding" is working
im getting 72mbps and i had been reading other cellphone that had similar problems @ 75mbps
to my understanding the phones were not channel bonding correctly.
i have had 3-4 people saying all kinds of stuff without really saying anything scientific.
i could have done that too but instead i knew there was a real problem
i kept digging and am sharing my experience as i find out what is really going on.
to check your "link speed" you can long press on your wifi connection and then go advance and scroll down and it should show it.
you can also get wifi analyzer and change the view and then select your connection
from what it looks like this galaxy s3 and my belkin n300 share router are not getting along.
i need another router to see if that is the problem or if it is really my phone and the software its running.
if other people with their devices would post your findings here it would be great
thanks

i take it that is at 5ghz and link speed is at 150
what is the fastest speeds you can get in wifi with only 2.4ghz?

40/50 is at 5ghz never tried setting the router to board cast 2.4ghz only. Is that the case why I do not see speeds higher then 40/50 on my S3. Never really thought about it

if you try to put your router at 2.4ghz (wireless n with 20/40) and connect your phone at "link speed 150mbps" you might still get that same 40/50
if your "link speed = 72mbps" like mine you will probably only get 20mbps down and prob same thing up
im pretty curious as it does seem like your phone and internet is working correctly

[Q] wifi to wired

So I have a tmobile note 3 with unlimited 4glte and im tired of paying 19.99 for my 1 mbps cable internet. I also have a bunch of Ethernet wired devices and don't want to spend 100 bucks for a bunch of wifi usb's and wifi ethernet adapters.
Im trying to connect my phone via wifi hotspot to my netger wrg 614 router. The router CAN be used as a repeater but it can only repeat wep encrypted signal. My note will only encrypt to wpa2 psk. sooo im looking for alternatives. Im thinking http://www.newegg.com/Product/Product.aspx?Item=N82E16833122373
this might work as a modem ?
If anyone has an alternative Id be super appreciative to hear it.

In case anyone wondered this setup works quite well. The adapter takes only a moment to setup and connects all my wired devices easily.

Portable WiFi router with phone as a USB modem?

Does such a thing exist where you can USB tether to a portable WiFi router to use your 3g/4g phone data and allow others to use your signal. This would be for an unrootable Android phone.

I might be not getting your question right, but doesn't Portable Wi-Fi hotspot feature on Android does the exact needs?

I was looking to get around paying Verizon $400 per year for using WiFi hotspot on an unrootable phone.
I bought a Nexus 6 and don't need a router.
