Hi - I cannot find this feature working - simply I start it up but cannot see the setup network via my laptops so I have excluded problem with it. Any ideas?
It is very unstable, I often never see the network after having enabled wifi router. The only solution I have found is to try several times and/or softreset the phone and try again.
Mine only works when the HD2 is right next to my laptop. The range is horrific. Still, I don't use the function. I'm quite happy internet sharing over a bluetooth connection.
i found that it wont work if you enable wireless N.but work with G without tweak using BSB
The Wifi router works very well for me and I use it regularly. This was one of the many features that attracted me to the HD2.
When I enable it on the HD2 from the com manager, my laptop connects automatically. Try restarting your laptop, once you had enabled the Wifi router to discover it if you are having problems.
In terms of range my HD2 is normally kept in the same room, and I have no problem with signal strength. Plus I rather keep my HD2 close so that I get my calls and messages. It is a mobile phone after all.
I can then surf for hours. (Low bandwidth web browsing eg reading XDA/email so not to go over internet allowance).
I have not yet enabled wireless N while using this feature.
I found that my PC could only see my HD2 as a Wi-Fi router when I switched my normal home broadband router off. Once I did that, it could suddenly see the HD2 and reported a full strength signal. I connected and everything worked perfectly.
Hope that helps.

What is the advantage over USB/bluetooth tethering?
Use case:
At work I like to use their wifi, but it doesn't allow me to use gmail.
So when connected to work's wifi I'd like it to use my 3G for gmail hosts or specific ports.
When back home I want it to go back to using my entire wifi as normal.
Others might like to use such a thing to send/read email via 3G so as not to use a public network, if paranoid.
Is this possible? If its not it sounds like a good candidate for extra Android functionality, as its a valid use case.
I'd like to point at a wifi access point and then list the hosts/ports that should be ignored, i.e. sent via 3G.
Android only keeps one active connection (either mobile or WiFi) for battery reasons, I suppose.
So unless someone manages to keep two simultaneous connections, you are pretty much out of luck.
I live very close to a hotel which has multiple SSID's that keep interfering with my ability to stay connected to my router.
I've tried hard coding a static ip on the phone, adding the mac address to router, even went as far as creating a separate unhidden network just for the phone. So far, nothing has worked.
So i was thinking that maybe there's a way to have the phone ignore certain signals, lock on to a preferred one or use WiFi but turn off the scanning feature. The only problem is that I haven't been able to find any settings or Apps that will allow me to do it.
So, if anyone has any ideas or suggestions as how, or if, I can make this work, I would greatly appreciate it.
I'm using a Droid 2 Rooted with 2.3.3 and have a Netgear N750 router.
BTW - none of the computers in the house are having this issue.

So, are you saying the phone constantly tries to leave your home wifi in favor of attempting to connect to the hotel's?
Yes, unless I'm within about 5 feet of my router, the hotel's signal makes the phone keep dropping and reconnecting over and over again.
Sent from my DROID2 using XDA App
Are the hotel's hotspots not WEP secured? That is so odd. If they're unsecured hotspots go over to the hotel and tell them to get their sh*t in order. Otherwise I'm out of ideas, sorry.
No, they are secure. WPA2 as is mine. I don't connect to them. My phone just detects them, drops my connection and tries to connect to them. So that leaves me with no connection and having to use 3G.
But there may be an easier solution to this. After spending a few hours on the Netgear site, it turns out that there is a bug in their firmware that causes signal strength fluctuations. They said a new release should be available in a few weeks.
In the meantime I've changed the channel on the router to auto select which seems to be helping.
I do appreciate you taking the time to assist.
Thanks!

Glad there's at least some kind of work around, wish I was of more assistance.
Having a similar problem with a samsung galaxy sii - current internet configuration is through AT&T U-Verse with built in Wireless G router in there Gateway. tried adding a Netgear dual band N router to my network and with the netgear's 2 wifi signals on then my phone just constantly goes into scanning mode and keeps trying to connect between the 3 - things work fine with the wifi turned off in the new netgear kind of defeating the purpose of me installing it - was hoping to have the phone use one of the N signals..
Block bt openzone connection pleaseee!
Desperately need an app for this? Is it not going to be possible for a way to block certain wifi signals because I'm actually going to rip next doors BT openzone router out of the wall and get a hammer to it! My HTC desire hd is insistent on connecting to its poor signal over our excellent one and the worst part is that you can't actually access the network unless you pay BT for a user account! Grrrr.... Please help
Try to connect the network you dont want, then go to wifi management in settings. Long press on the network you dont want and hit forget network. Then your phone shouldnt automatically connect to it unless you tell it to.
This is driving me insane!
When I have WiFi enabled at the office, my Samsung Galaxy Note (stock ICS, rooted) constantly receives incoming data and I haven't got a clue which setting, app or service is causing this.
SystemPanel registers a nonstop stream of incoming traffic at 8 to 10 Kbps.
TrafficStats shows an accumulation of Received data under Total WiFi, but can't seem to link it a particular app or service: after resetting the data, no processes appear but the incoming data keeps on growing.
All sync options are off, I've tried to kill every running app or service (one by one, all at once), I've tried to block all traffic using Droidwall. As soon as WiFi is enabled, the incoming stream is unstoppable. When switching to 3G, there's no incoming traffic.
But to make matters even more mysterious, I do not have this problem with my WiFi connection at home.
It only occurs at the office, only on WiFi and (as far as I know) only on my phone.
Any ideas?
This is simply because your wifi antenna still "hears" the data going trough the wireless network on wich you are connecter. Event if your phone doesn't asks for any data at the moment the traffic there is on the network will still be counted by the wifi chip on your phone.
It will be the same on any public network or if you have another phone or a computer connecter on the same wireless router and generating traffic.
Thanks for replying, John!
That sounds very plausible, but then I still have to figure out why only my phone is registering this traffic - maybe it's an ICS thing or brand specific?
And I'll try to 'reproduce' it at home by connecting a laptop at the same time.
I think that the above is correct. That may be default behavior.

Well, I've tried to connect several devices at once on my home WiFi network, but it did not reproduce the incoming traffic problem I experience at work.
There were a few incoming bytes registered, not nearly as much as the constant stream of 10 Kbps at the office network...
Your works wifi may be set up like that. Who Knows?

Well, our it-department certainly does not.
You're probably right that this is normal behavior. I'll just have to figure out which drains less battery under these circumstances, WiFi or 3G. Thanks anyway for replying.
I'm on the mobile app, but if you have GSM then just switch to 2g until you use it.

About this, it is simply that at your office there is traffic on the network (download/upload) while at home simply having devices connected doesn't generate traffic or almost none. Start several dl on several devices (phone laptop) (guess 2-3 is enough, maybe even one but not sure, not en expert after all ) then you should notice signifficant traffic on your phone, I guess!
So interesting I find this thread because I have the exact same problem!!!!
How I noticed it...when I am at home I drop 1% battery on Wifi per hour. 10hours = 10% (sometimes less).
I go to work on the Wifi, I DONT USE ANYTHING ON THE PHONE and the battery is DRAINING LIKE CRAZY!!! 5%/h or more!!!
( I am in airplane mode in both place)
So I was thinking, WTF with this work wifi, i am not doing anything at all on it. Then I look at my wifi icon I have a constant RECEIVE icon. And I bet my phone does not go to sleep or something.
So why in the world my work wifi is draining my battery and the one at home is not. I will check tonight but I dont think I have traffic like this. I am registering 5-6kbytes/s for nothing. The explanation given above is hands-waving. I do not agree with it fully. YEs sure there are several pings and beacon emitted back and forth but i do not think it is enough to cause 5-6kbytes/sec . The wifi is not in Monitor mode and it only receives the packets destined to my phone.
This is madness!!!! BTW When I had a different kernel on back on ICS this behavior stopped. I will try to monitor again.

Hey kalinusa, did you find a solution to this problem?
I'm currently on the SpeedMod kernel, but that does not seem to make a difference to the 'office WiFi behavior' (so I keep my phone on mobile data).
I don't want to speak out of my ass, because I haven't a clue how the app works.
As far as I can guess SSH tunnel may help you. I would hope someone else could tell me I'm right, but I'm probably wrong.
I have had this same problem with two of my devices. The first is a Samsung Captivate with the last AOKP ICS build. The second is a Google Nexus 7 with AOKP's first Jelly Bean build (it happened when I had stock as well).
This only happens when I'm connected to WiFi at my university. The down arrow on the WiFi icon is ALWAYS on and it drains the battery. At home, I don't have these problems.
I emailed my university's IT department but I'm not sure if there's anything they can do. Anyone have any suggestions? Thanks.
I have exactly the same problem, but I think I found the reason which is causing it. I think that some of the routers are capable of the multicast over the wifi and then we can get a constant wifi traffic. I tested it at home, where I have enabled multicast over wifi and my phone wifi receiving the data all the time, even if it is in sleep. Now I'm in the office where we do not have such capable router with multicast over wifi and my phone wifi behavior is as expected. When I will be at home I will test it again with my router and with disabled multicast over wifi and hopefully it will solve this issue.

More than multicasts it could be broadcasts, what are you reaceiving. For example if you don't use WINS server in Windows domain, all computers use broadcast to get IP address for a computer name (if you dont use DNS name, but that's another story). At home, where aren't many computers, there are very few broadcasts. But somewhere, where a large amount of computers is on the same network (not splitted to broadcast domais), number of broadcasts would dramatically increase
btw. if you connect a PC to the same network as your phone and stop ALL running applications (mainly instant messangers, web browsers, e-mail clients) you should see the same network bandwidth in use as on your cell phone.

Interesting. Roughly how many devices would need to be on the same network, to see that kind of traffic load?

It depends on what you consier as network load. If you start a network monitor like Wireshark or MS Network monitor and even if there is one computer on the network, you wil see "some" traffic (from time to time a few network packets). To generate constant network load, you'll need a few dozens of computers. And it always depends on how the network is designed and what applications the computers run. If all computers connect to a server, the network load will be a lot lower than if the computers share resources among them.
Or you can design your network in such way, that you divide computers into segments, where computers can communicate only with computers in its segment (or with some distant servers). This way the network load will dramatically decrease, as computers from different segments would not interfere.
I currently only have one computer connected to my home network atm via wifi, and it keeps a constant broadcast going to my phone for some unknown reason. I thought it was my dlna server, so I shut that off, and it is still broadcasting _something_... Its causing quite a battery drain, and unfortunately I cant seem to find the root of the issue. I've trolled through my router settings -- multicasting isnt on -- so Im at a loss. =\

It can be caused also with the Media servers which runs on PC, also DHCP etc. It is not easy to eliminate all broadcast traffic and sadly our phones react at all that multicast packets.
tl;dr: When my phone (Sony Xperia Z5 compact, Android 6) connects to a wifi with no internet, I want to use the local network on the wifi but use the internet from my mobile data. Instead what happens mobile data doesn't switch back on while connected to wifi with no internet.
I have been trying to find a solution for this since forever. My camera creates a local wifi connection which I can connect to to view the camera as well as controlling it. The downside is that while connected to this network my cellular data gets switched off, despite this wifi network not having any internet. So while using my camera I have no way to access the internet. It wasn't a huge problem up until recently when the app I use is introducing livestreaming. I really want to use it but I am unable to find any way how to keep my phone connected to this wifi network (and being able to use it), while any internet data goes over 4G. I am using android 6.0.1. I am quite sure I was able to do this on my previous phone with an older Android version but I cannot find said option (smart network switch or something?) anymore in the wifi settings. Nor any recent similar topics with people with the same question? Anyone that knows more about this?
My phone is rooted. If I need to do any system changes I can do that.
I didnt get what you were trying saying.Do you know that you cant use mobile data and wifi simultaneously unless your device is rooted.If your phone is rooted then try using "download booster"

Err, sorry, lol. I have wifi network that has no internet, just a local network. I'd like to be connected to that wifi network AND be able to use internet over my mobile data both at the same time. As it is right now, my mobile data gets disabled even when the wifi network has no internet access.
I have talked to two friends of mine about it and both say this is already possible in Android. One friend sent me a screenshot of an option he has in his wifi settings called 'Switch to mobile data' which gets enabled when the wifi network has no internet. My other friend said he doesn't have this option but claims it has been a default feature of Android since lollipop. He tested it on his phone and indeed it works as expected. Both have an unrooted phone with stock Android. So now there is me with my brand new phone and Android 6 and I can't find this option nor does it seem to do what I want by default. I'm confused.
As I mentioned, my phone is rooted so if there is a way to turn this feature on using root, I can totally do that if someone knows how.
As i said try using "Download Booster" It allows you to use wifi and mobile data at the same time just google it.

That appears to be just a download manager if I am correct? I don't need to download anything. I just want to be able to use my existing apps to use my mobile internet when I am connected to wifi (that has no internet).
This is the exactly the thing I'm after. Screenshot from my friend's phone (LG G4 with Android 6.0): (*link removed). My other friend who also has this functionality working has a Nexus 5 with Android 6.0.1.
* Forum doesn't let me post screenshots.. But basically in his wifi settings he has an option called "Switch to mobile data". The box says "Internet unavailable via connected Wi-Fi. Stay connected to Wi-Fi, but use mobile data. Data charges may apply."
Again, I have Sony Xperia Z5 compact with Android 6.0.1 and I can't find this. Have I bought the wrong phone or is it fixable? At this point I am more than happy to even take a custom rom route.
You cannot use wifi and internet at the same time as they are completely different hardware components, using different air waves, so there's no conflicts between them. Better use internet through your wifi or use bluetooth tethering.As for the "switch to mobile data option" it disconnectes you from your wifi if it has no internet and connects you to your mobile data so it doesnt lets you use your wifi and mobile data at the same time

It actually clearly mentions that it keeps connected to the wifi. He tested it and indeed he could use the local network on the wifi side and use the internet through his mobile data simultaneously. Both friends haven't rooted their phones or anything. This is just a default functionality for them. I have now tested it also on my older phones (Oneplus One and HTC One M8) and all phones can't have both connections open at the same time.
This wifi network is created by my camera by the way and I can't change much about it. The DJI drone I control does the same thing. When I am connected to the camera or drone I lose my mobile internet connection.
I don't have any other device that has access to internet here. We don't have cabled internet, only mobile internet.
Interestingly, in the developers options there is an option called "Mobile data always active" ("Always keep mobile data active, even when Wi-Fi is active"). I've tried it many times, rebooted my phone but this doesn't actually do anything. Even with this option on when wifi is connected the mobile data gets turned off.
This is beyond annoying!
I too have struggled to find a solution to this problem. I do not have a WAN connection to my home network. It is LAN only. I have four PC's, three Sonos speakers, two hdhomerun TV tuners, and various hand held devices that all use the LAN. All I want to do is be able to use my Moto X Pure to control Sonos and file sync to my LAN via wifi and simultaneously use mobile data for WAN stuff. I know the mobile connection is active with wifi enabled because I can see it when running if config, up route show etc... I am trying to learn about the routing tables to see if I can fix this myself. I love my android devices and am loyal, but this is beyond dumb! Any suggestions????
How to fix for android
okay so for anyone who doesnt know still go into the about phone option in your phone settings, then click on kernel version, build model, etc til one pops up with a flash notification saying click so many more times and youll become a dev. once you done that go into the developer menu and scroll too wifi assist or force mobile data upon wifi connection. exit out , open your app , bobs your uncle
Thank you for the answer.
I tried with my Huawei but it doesn't work. Could you tell with which phone you made it work ? Thank you !!
Ok here we go, after 12 years this my first post.
Above suggestions related with developer options nothing to do with OPs requirement. Those option only allows the device rapidly switch to mobile data when the WiFi signal gets weak. Since you always close to your DSLR camera it solves nothing because WiFi signal is always strong.
Root cause of the problem is you can not have 2 default gateways (i.e. router address) for your networks in any operating system (Actually you can but you have to set static routes, which is a pain in the ass for regular users)
iOS handles this in a very simple way. Set your wifi connection to static IP address instead of DHCP and leave your default gateway or router address blank. Viola you can have 3G/LTE data while you connected your camera and now you can sent your downloaded pictures via Whatapp while you still connected to your camera via WiFi. (In my case Panasonic Lumix)
I stumbled upon this thread via Google since I needed the same thing now with Android. But iOS way failed. Actually I am shocked that you cannot leave WiFi Gateway address blank in Androdid 8.0! Save button grays out if you leave it blank. This is really weird. At least with Galaxy S8 Duos with Android 8.0
So anybody know how to setup a WiFi network without a default gateway, please share.
Is this phone specific or something? Never had that happen, I have no problem with wifi being on without internet and using cell data.
I don't think the UI really exposes anything like it directly but you can technically have multiple gateways; it's not something your average user will understand (policy routing)..
Having said that, if you're attached to an AP you should at least see a /24 route out your wireless interface (standard dhcp lease). It's quite common for the AP to have client isolation but are you sure you're not using something like Wifi Direct or even adhoc?
Similar Experience
I have been through this experience long ago. All I did was to sell the phone and bought a new one.
