This is a BIG Deal!!

This phone doesn't support ad hoc wifi connections? I'm currently on travel overseas and I can't seem to share an Internet connection with my laptop (connected via LAN) or iPhone 3GS (local 3G service). Has anyone been able to detect an ad hoc wifi network with this phone.
I can detect ad hoc networks with 3rd party wifi apps on the marketplace but when I attempt to connect, it directs me to the general wifi settings screen where the network is gone!!
Anyone else with this issue?

Did you ever see that it was an international phone?

WTF?? I'm talkin about a Wifi connection here buddy...lol. The EVO 4G doesn't detect or connect to ad hoc wifi networks. That's the topic...

while i dont know if it does or doesnt...i could believe it...because there is a few phones out there that dont - blackberry is one.

The wireless tether app for Android makes it into an ad hoc device.

But the problem is that it won't DETECT an ad-hoc device. Interesting. So if I had, say a hero with WiFi tether enabled, I wouldn't be able to see the WiFi with my EVO?
I don't connect to ad-hoc networks myself, unless I"m trying to tether something (the only use I can see.) Interesting that the EVO can't see them though, they should still show up..huh.

Seems to be some type of security feature on the device (WiFi Scanner app detects) that prevents it from detecting ad hoc wireless networks. My PS3 also has the same issue. Just wanted to point it out the issue...perhaps we need to root to manually connect?

just to be clear, you're trying to share your laptops internet with your Evo?

Yes, the laptop has Internet access via LAN and I am using the built in ICS (Internet Connection Sharing) Wifi Sharing on Windows Vista. Every other device I've had before had no issue detecting the network...I can see the access point right now on my iPhone and iPod Touch :-/

Found this workaround:
http://www.soligard.com/technology/how-to-connect-htc-hero-to-ad-hoc-wifi-network/
I'll try this later and report back.

I don't know if I'm experiencing the same problem but maybe someone can tell what I'm doing wrong. I rooted my phone by unrevoked and installed the Android-Wifi-Tether program. I've activated the program and it's sending out a signal. I then use my Windows Vista comp. to located it and it shows my phone as an "Ad-Hoc Network" when I connect to it, it says your computer is not configured for this. I'm not sure now what I should do, is there a problem with my EVO, or this something I need to do with the computer.

OP you are absolutely correct. I actually was trying the exact example you stated. I had created an ad-hoc wireless hotspot/network via Wireless Tether App on my Hero and my EVO just plain did not see it. It saw a million other networks that were much farther away, but not my Hero that was right next to it. This is unfortunate. Hopefully a workaround is found soon.

A lot of devices don't connect via an Ad Hoc network... which makes me wonder what its purpose even is :/ One reason I submitted the idea (true wifi hotspot) I did to the WP7 app contest.

This is what made me return my Archos 5 Android tablet and stick to my iPod Touch.
My scenario, i have a Sprint Treo and an iPod Touch (and iPad as well) and usually turn my Treo into a wifi router via wmwifirouter and use iPod Touch this way. Been doing this for years (with other devices too like the Nokia N800/N810), and wanted to test out Android. I got the Archos 5 tablet and was saddened not to be able to use my Treo's ad-hoc wifi. Back it went.
It seems that Android devices do not connect to ad-hoc wifi networks. Shame indeed. Also i think the Zune HD does not connect to ad-hoc as well.
Is it an O.S specific issue?

Android wifi tether

Hi All,
I wondering if someone can help me out. I rooted my epic and installed the latest android wifi tether and everything seems to be going okay as I am able to start tether and see the normal tether screen displaying Download 0.4kB and Upload of 0.3kB.
However i am not able to see connect correctly on my laptop. In the laptop, under wireless network connections, i see EpicTether (which i choose as the ssid) but the icon (right of the word EpicTether) looks different than the icons from my home wifi router. The EpicTether's icon is three blue boxes in the shape of a triangle where my home wifi shows the normal guage of wifi connectivity strength. I am using windows 7 premium by the way.
I've tried changing the channels on the epic, tried enable access-control under settings to no avail...
can someone please help? thanks.

Android WiFi tether is an Ad-Hoc network (device to device), not an infrastructure network like your home wifi is. That's why the icon is different.
Why it cannot connect could be 1000000 different things. Is the laptop part of a company domain and its possible that policies are preventing connection to an AdHoc type connection?

Thanks for the explanation. so that icon is normal.
My laptop is not a company laptop, it is pretty basic for home surfing use.

"pretty basic" to me translates as "should connect" lol. Not sure where you should go from there. I have heard lots of windows 7 ad hoc issues though. Search around google for "Windows 7 cant connect to ad hoc" and see what kind of fixes you see.

Thanks again.... made some success...
i read that the intel drivers for the internal wireless card may need updated drivers for the ad-hoc....
installed the new drivers and am able to connect now!... but will not provide me internet access.

Restart the computer (usually works most times), and or try releasing and renewing I.P address.

ad hoc for xoom

so with my minimal knowledge of phone stuffs ive kinda learned that when i run the wireless tether for root app on my phone it uses ad hoc to supply other computers with internet... basically im asking, will my evo be able to supply my xoom with internet?

Not at the moment, no support for Ad-Hoc networks in HC, not sure if there ever will be - very annoying.

I'm not sure but I believe there is a new version of Wireless Tether that will allow such a connection. When I first tried the Kindle connecting to my DX, it wouldn't connect. With the new version, it does.

My Xoom connects to my DX with no problems.

Go download Wireless Tether from the website. The experimental one is called Wifi Tether now. Works like a charm for infrastructure mode so that the Xoom can tether with your phone. Also Bluetooth seems to work fine as well.

Is the Wireless tether for the phone or the Xoom (or both)? I need an option for the iPhone in case the steps posted here won't work!

is this an app that enables ad-hoc detection on the Xoom,
or
does it just provide a full wifi hotspot tethering feature for Android devices?
I also use an iPhone which supplies an ad-hoc hotspot connection that I need my Xoom to recognize and connect to.

So does that mean you got it to work that way? Is the app available through the Market?

No its not available in the market. Google wireless tether and look for wifi tether. The new app sends the signal via infrastructure mode. I think it applies to certain phone like Droid X and EVO.

The Wireless Tether app is ran on the host phone wanting to be turned into a wifi hotspot. There are certain phones that run in Ad-Hoc mode in default (aka Droid 1) and the only option to tether the Xoom to them is via bluetooth. As others have said, the new version "WiFi Tether" is apparently enabling infrastructure mode rather than Ad-hoc mode, something that the Xoom can actually connect to.
There is no app that you install on the Xoom. When the WiFi Tether is ran on the host device, the Xoom just connects to it as a WiFi router and works just fine (or bluetooth if thats what you're doing).
So OP, if you can't get the new version of WiFi tether to work for you and your Xoom, try the Bluetooth tethering option, it's been shown in detail in a thread here how to do it, and it should work just fine.

The app is for android, and for the host device not the Xoom, so you'll need to Bluetooth tether your iPhone.

wpa_supplicant
I understand exactly what the OP is talking about, as i'm trying to do the same thing. What makes matters worse, is that ad-hoc connections ARE possible in android. Meaning android can connect to ad-hoc networks, but it requires swapping out the wpa_suppplicant file in system/bin with a modified one that doesn't filter out ad-hoc networks.
i've even tested this on my EVO, and it connects to other android phones incapable of broadcasting in infrastructure mode, it even connects to my ubuntu netbook broadcasting in ad-hoc...
(if you want to see what i'm talking, just search the forums for wpa_supplicant, something will turn up )
I've tried doing the same "fix" with my xoom, but it doesn't take. Using ADB or root explorer, i've replaced the orignal (making sure to save a copy just in case) and fixed permissions to 775, but it doesn't take. The wifi antenna will turn on, but it doesn't find anything once being replaced, not even saved networks or access points. I can get wifi back by restoring my backup, but i'm at a loss as to why it doesn't work on the xoom (3.0) but does with my evo (2.3).
as a side note, i'm using the right replacement for the wpa version returned by entering
"wpa_supplicant -v" in a terminal emulator or adb. It returns version v0.6.10 and there is a working, modified, v0.6.10 that should make things work, but doesn't....
anyway, if anyone has any input, i would love to hear it!

I am in the same boat. Regardless of whatever permission settings I have tried (mentioned in the dev forums that I can't yet post in), I still get a dead wifi with the new supplicant file.

Ah, I feel better now. It must have been the supplicant file, as I found this other one and it worked without permission modifications first time out.
You will have to google "xoom supplicant" and use the file found on the first response (android.net)-I can't post the link- the downside to attitude having, overlord type forums is inability for new users to provide any help, or at least with any convenience.

i try connecting my xoom to my computer, and it wouldn't work. i have the "Intel My Wifi Technology" but each time i set up a connection, the xoom finds it, but will take like a minute trying to connect and all i see on the xoom is "Obtaining IP address". it shows on my computer that a new device is connected. maybe this only works computer to computer. cuz i have had success with another laptop connecting to my computer with no problem.

I am using the Launchpad kernel and the WPASupplicant file and am connected to my phone's ad-Hoc network now. I used the beta Wi-Fi Tether and it worked great, but crashed my Samsung Galaxy S at least twice a day. So I installed the WPA file without setting any special permissions, just used Root Explorer to copy it an it worked fine.

Is there a way to connect on a ad-hoc hostet by a laptop (win7) yet?
That would be interesting, cause if it work this way, it will work for every phone or something else!

Hey Guys,
i am having a little problem. i am using the Intel My Wifi Technology. and i don't know if i am doiing something wrong or this is just not possible. but i try connecting my xoom to my laptop, and it is not working or connecting. i get a message on the xoom that say's Obtaining IP address", but nothing happen on the xoom. is this not yet possible on the xoom. i don't know if this is consider ad-hoc network or not, cuz i am new to all this.
but here is the link to intel website for the program i am using as a wifi hotspot.
http://www.intel.com/products/wireless/mywifi.htm
and here is a video of what the program does.

anyone with knowlwdge on this please help me understand what i am doing wrong or not doing. or even if this is a possibility.

If you're not opposed to rooting your Xoom, here's another option. I just unlocked and rooted my WiFi-only Xoom yesterday, and inserted the supplicant file in this thread: http://forum.xda-developers.com/showthread.php?t=1033314
It works like a charm! I'm running a WinMo Touch Pro 2 with WMWiFiRouter, and the Xoom now sees and properly connects to Ad Hoc networks. And, it still works with all other networks.
I don't know which way you prefer to attack the problem (from the Xoom or the phone), but I've been thrilled ever since I got all this done yesterday. Everything else on the Xoom is great, and now I've got the working SD card as well.

Wifi problem on my hd2

I just got an HD2 (flashed windows 7) and when I try connecting it to my home network, it will say connecting and then after a while it shows "Connection Unsuccessful"
I have a linksys wrt610n router, and i even tried resetting the router but still the problem persists.
First I thought it might be a phone issue, but it was connecting perfectly fine to the local library's hotspot and a starbucks hotspot. So that means, it's definitely something wrong with my house network that it won't let me connect.
All the other devices : ipod touch, laptop, xbox 360, connect fine to the network.
Please help me with this issue, as I am using HD2 without a data plan so without wifi,i cant fully use the functionalities of hd2.
Thanks.

Is your ssid hidden? Wp7 has troubles with that, you could try the wp7 section without sounding cocky, there is a couple of threads mate about it, more help in there.

Yeah, even before flashing the rom the same problem existed. I think it's something wrong with my network, as I am able to connect perfectly fine with at a starbucks hotspot.
And no it's not hidden. The networks visible and the name of the network is with spaces -> cow boy , does that make a difference?

do you have mac filtering or anything turned on liked that in the router setup ??
do you have any crazy characters in the password like %^& ??? that could be a prob not sure also check these out looks like it could be a sd card problem, have you ever had it connect using android or winmo 6.5???

Kindle Fire WiFi Oddity

I got a Kindle Fire for Christmas, and a few days later bought an Asus RT-N16 (it has DD-WRT on it) to use for WiFi for it (we have 2 other APs in the house, but they're not close enough to my bed to use the tablet in bed, which was something that I wanted to do).
It was working perfectly up until the day before yesterday. Now the Fire won't connect to the SSID at all. Sometimes it doesn't even recognize that the SSID is there at all. Even the WiFi Analyzer app sometimes won't see the SSID.
I'd think it was an AP problem, but going to the AP's configuration page shows that the radio is, indeed, on, and I can pick up my phone (HTC HD2 w/CyanogenMod 7) and connect and use the network perfectly.
Any thoughts?

I have the same issue I think. I have a wifi extender set up in my apartment out back because the main ap from the house doesnt provide a good signal in my apt. Other devices can have them both set up and switch accordingly, but my fire with CM7 installed will constantly only use the main one unless I forget it temporarily.
Not the best solution but a temp workaround.

If you are on stock than you go to wirless networks and then advenced settings and change it to Japan i had The same problem

That's not the problem I'm having.
Even if I forget everything but the "target" SSID, it still won't connect at all, ever.
The only way I can get it to connect to this AP is to set the AP to G-only and turn security off.
My phone continues to connect flawlessly in all situations, however...
I don't really consider this a "solution" since no security is...no security...but I guess it'll have to do because as soon as I turn encryption back on the tablet just doesn't connect again.

I changed it to use all 14 channels, and I even tried forcing the AP to a certain channel that I knew the device would connect to, and the problem still did not disapper.
