I am initiating the design of an application that would require an Android phone to connect to another Android phone via Ad-Hoc networking with or w/o security. I would like to know if Android supports ad-hoc networking. I would also like to know what is the average range of the wifi signal from an Android handset point-to-point with no obstructions. I cannot find any information about this on the web.

I got the Hero on 3UK yesterday. As soon as I booted it up it found a number of wireless networks and I was able to connect to my BeBox with no problems. Later on last night and continuing today, it can't find any networks in range. It shows the BeBox as 'remembered' but not in range. Even tho I'm obviously sitting near it. I've rebooted the phone today and no change. I installed the Fonera application yesterday and thought it might be causing problems so disabled it and still the problem was there.

Whenever I turn on the wifi, or I become in range of my WPA2 network, it doesn't always connect. I say "always" because it seems to be random. If I toggle wifi on or off, it doesn't always connect. Sometimes it connects after 30+ seconds. Every other device connects just fine.
The only sure way to get it to connect is to force it to rescan, usually by going to Settings and displaying all SSIDs in range. THEN it connects, always and immediately.
The even sillier thing is, it will alert me of open networks, but never connect to my own saved network.
I have a droid and the range I get with wifi compared to a laptop is horrible. The networks I have tested on are all 802.11g. Is this just normal because of the antenna size on the droid or is there something I can do to improve it? I feel like I have to be right next to the access point to have a good connection.
View 2 Replies View RelatedI realize that it would probably require boosting antenna power and thus reduce battery life but, if I am prepared to accept that, can I programatically extend wifi range?
View 1 Replies View RelatedNot sure if any of you guys have the same problem but when I leave my Wifi on all day, and return home from work, my home Wifi never picks back up. When I toggle my Wifi on and off, it picks up again. My signal is always above 1 bar when on Wifi in my house, it just does NOT automatically connect anymore.
View 4 Replies View RelatedQuick background, I am still on a $30/month SERO plan with my Touch Pro 2 and waiting to get a $10/24 month discount but Sprint has put a halt to all discounts for the time being, so I'm going to try when the iPhone 4 comes out and when Verizon gets their Droid X. I was going to sell my EVO but it seems I might as well keep it since I'm going to eventually use it.
So in the meantime, I'm going to hold onto the TP2/SERO and use the EVO when I am within a WiFi network. Thing is sometimes I want to bring the EVO out, so I thought maybe I could open up a WiFi hotspot with HTC's Wifi-Router software and connect to it with the EVO. But the EVO isn't recognizing the WiFi hotspot. My laptop can recognize it though. I tried to add the WiFi network but it'll say "Not in range, remembered".
Did a search but couldn't see a solution. I have 3 email accounts set up. All of them work for both send and receive while connected to any WiFi. However, when not in range of WiFi I can receive emails but not send.
View 2 Replies View Related I recently bought Zync Z930 7" Android tablet. Everything is working fine, except for the WiFi. My router is Belkin G Wireless 40961F. The tablet finds the WiFi and connects to it and works flawlessly. But as soon as I move to upstairs, the connection is lost and it says Wifi Not in Range. I tried changing the pass from WPA to WEP and finally no password at all. Now the connection stays for more time. I tried putting "Keep On Wifi " to " Never (increases data usage) " . The connection says " Good Signal Strength ", but it keeps flashing between "Connecting " and "saved" .
Do I need to contact the vendor ? as I bought it from Ebay, I need to return it ASAP if its a hardware problem. BtW, it says the tab runs on a custom ROM.
i have a stylistic M532 tablet.insert 3g sim cart disconnect the wifi connection, and wifi display " Not in Range" message.the wifi don't connect until i eject sim cart.

View 1 Replies View RelatedI'm trying to scan for wireless networks and found this helpful source on the net. Unfortunately it's not working and I have no idea why. My problem is that I can't wait 10 minutes for the result - I need them within a few seconds and thought about setting the boolean variable waiting on false as soon as I get a result, well it runs forever. Looks like nothing is received.

I am programming for google android and I wonder if the scans for wireless 802.11 networks are done passively or actively? I mean: Does the device actually emit a beacon request signal on
WifiManager.startScan()
Or does it just listen for beacons sent periodically by the access points?
We have an application where we'd like to use the WiFi connection on a local network (intranet) with no Internet connectivity, and use the 3G connection simultaneously as the data connection to the internet. To summarize:
We need to connect to two distinct networks at the same time - We need data traffic to be properly routed to the appropriate network based on its IP address - We need both radios (WiFi and 3G) on and active. This can easily be done on the iPhone, but not sure if it can be done on the Android.
I'm looking for an app that will automatically enable my wifi for designated networks. Basically, the only location currently I really desire to use wifi is at home since if I'm at home, my phone is likely charging (since wifi eats battery) and the speed beats 3G. I'm going through appbrain.com and finding a lot of apps that automatically scan and connect to open networks, automatically connect to the fastest network, a bunch of wifi toggle widgets...nothing really for making conditions for what networks it will connect to, especially one that has a password.
View 4 Replies View RelatedI'm downloaded several wifi apps, but I'm looking for one that will automatically connect to open networks.
Or at least to saved/remembered networks without me having to scan and connect.
Anybody know an app that can control what to sync, and what not to sync on a WiFi network. I would like my hero only to sync exchange when at work.
View 1 Replies View RelatedI got 2 Sprint HTC Heros 3 wks ago. They work fine with any WiFi network that shows up as available. Other WiFi networks are completely ignored and do not show up in the list of available networks. I installed WiFi Analyzer and it is also prevented from seeing the same "invisible" networks. One WiFi network which does not show up is my home network. Last weekend I was at a B&B in another state and had the same problem with their network. Their network was up and running and visible to other hardware but not to our Heros.
Our home WiFi router is a Linksys WRT110 running WPA-2 Personal AES. There typically are three devices on this network: 2 @ g and 1 @ n. I have seen other WPA-2 Personal networks show up as Available while traveling but have no idea what routers were used. I called Sprint support and eventually got to someone in Tech support who put me on hold after I explained the symptoms. 20 min later the call was dropped. So much for Sprint tech support .
Now I wish there was a way to connect my Non-Rooted Froyo Incredible to Ad-Hoc WiFi networks, but I can't seem to find a way. Does anyone know of any ways to connect my Incredible to my Ad-Hoc WiFi networks? Because that would be the only reason I would root my incredible, but I wouldn't do it if there wasn't a solution available.

View 1 Replies View RelatedMy SGS (well its actually my wife's but I use it also) will not connect to WiFi networks, other than the one we have at home. If we are out, the phone will be able to see lots of WiFi networks, but it cannot connect to any of them as it says the signal is poor. Other people can be sat right next to other with other phones and have no problem connecting and they have strong signals. At home it will connect, but even then there is only one bar of signal, even though the router is in the same room. It appears that the phone just cannot get a strong enough signal to connect.
View 1 Replies View RelatedThe wireless network in my area follows the EALP/PEAP protocol which isn't supported on Android phones. So, I tried setting up local WiFi hotspots from my laptop to enable WiFi. But my phone doesn't detect that wireless network at all. My friend's Nokia E51 detects the hotspot, but not my HTC Desire. I tried detecting hotspots created from other laptops but the result remains the same. The E51 detects it but the Desire does not. Do I have to change some settings that I am unaware of?
View 5 Replies View RelatedI started using WiFi exclusively at home and my office after reading about the benefits on here. I noticed a tremendous increase in battery life. But when I'm on WiFi at my gf's parents house, the battery drain isn't even about the same as 3G it seems like it is much worse. What could be causing this? The signal strength is often better at this location than home/office so that shouldn't be the problem.

View 4 Replies View RelatedIn Jan. I switched from Sprint to a different carrier and got a new phone with the new carrier which left me with my HTC Evo 4G and I've been trying to use the Wifi so I can use it at work or at home when I don't feel like using my laptop and whenever I try to turn my WiFi on it just turns on then off and tells me "Unable to scan for networks".
I've noticed that it says that my IP address is unknown and Bluetooth isn't working either. I did a factory reset on my phone and all that did was delete my Doctor Who background.
Sidenote: my husband was on my family plan and he had the same phone with the same service and his WiFi is working fine.
After rooting with DooMLoRD v4 tool my china A6380 Android 2.3, which has mt6516 416MHz and Android 2.2.1 instead, wifi stopped working.
Tried unroot and factory reset but no luck, still "Unable to scan for networks".

The problem I'm experiencing is that I am not receiving push notifications of any kind while my phone is locked/sleeping (screen off) on my wifi network at work.
My home wifi network and mobile connection have no such problems, i get the notifications instantly. My wifi is set to never sleep.
I do get the notifications a couple of seconds after I unlock my phone though. Not very useful because I have to keep checking my phone.
Not sure if this has anything to do with it but my home network is WEP secured and work is WPA/WPA2 secured.
basically I have 2 routers with different SSIDs set up in my house.
I was wondering if there is a way I can have it automatically switch to the one with a better connection through an app or script of some sort or a way that I can at least make a shortcut on my launcher to do this?
now that I think about I could toggle wifi off and on but is there a better way?
I just installed the wifi tether. i opened the app up, changed my ssid, and pasephrase. I then went to my laptop to search for wireless networks and I can't find my droid. What could I have done wrong. also...i thought maybe I had to turn on wifi in the phone settings. when I went to turn on, it said it was unable to turn on wifi. I went back to the tether and turned it off but the phone settings still could not turn on wifi.
View 10 Replies View RelatedIt happened to me last night on the Captivate. I tried battery pulls, deleting the WiFi nets, etc., but it still kept turning WiFi off within a minute of turning it on. I did a factory reset (I'm getting better at this process. Can restore my device back to its former glory within an hour).
