I've heard some people say that when they're rooted, their wireless tether, another Android device such as a tablet or phone can't pick it up do to it being an adhoc network.
Question is, what's an adhoc network?
And how come MY wireless tether can be picked up by my Android tablet. But someone elses wireless tether doesn't work on their Android tablet?

On wireless computer networks, ad-hoc mode is a method for wireless devices to directly communicate with each other. Operating in ad-hoc mode allows all wireless devices within range of each other to discover and communicate in peer-to-peer fashion without involving central access points (including those built in to broadband wireless routers).
To set up an ad-hoc wireless network, each wireless adapter must be configured for ad-hoc mode versus the alternative infrastructure mode. In addition, all wireless adapters on the ad-hoc network must use the same SSID and the same channel number.
An ad-hoc network tends to feature a small group of devices all in very close proximity to each other. Performance suffers as the number of devices grows, and a large ad-hoc network quickly becomes difficult to manage. Ad-hoc networks cannot bridge to wired LANs or to the Internet without installing a special-purpose gateway.
Ad hoc networks make sense when needing to build a small, all-wireless LAN quickly and spend the minimum amount of money on equipment. Ad hoc networks also work well as a temporary fallback mechanism if normally-available infrastructure mode gear (access points or routers) stop functioning.
Infrastructure mode wireless networking bridges (joins) a wireless network to a wired Ethernet network. Infrastructure mode wireless also supports central connection points for WLAN clients.
A wireless access point (AP) is required for infrastructure mode wireless networking. To join the WLAN, the AP and all wireless clients must be configured to use the same SSID. The AP is then cabled to the wired network to allow wireless clients access to, for example, Internet connections or printers. Additional APs can be added to the WLAN to increase the reach of the infrastructure and support any number of wireless clients.
Compared to the alternative, ad-hoc wireless networks, infrastructure mode networks offer the advantage of scalability, centralized security management and improved reach. The disadvantage of infrastructure wireless networks is simply the additional cost to purchase AP hardware.
Note that home wireless routers all feature a built-in AP to support infrastructure mode.
awesome information thanks.
But any ideas for the 2nd question? about connecting android devices to other adhoc networks that work and dont work......
Think of it like this. Hotspot mod (infrastructure) on this phone is like connecting to a router. Wireless tether (ad hoc) is like doing internet connection sharing on a computer. You'll have to find a mod for the device that can't see or connect to ad hoc, to make it work. There are different ways to accomplish the same thing in different devices. With a galaxy tab, it's replacing a file. I'm probably wrong but with the Xoom, you need a modded kernel.
Also, as the saying goes, Google is your friend.
I couldn't connect my wife's laptop to the hotspot on my phone until I lowered the security on the hotspot settings to WPA. Default was WPA2. Something to keep in mind if a device won't connect.

Hi everybody,
I can think of half a dozen ridiculous applications for a wi-fi connection between my xda2s and my PC, but I'm having problems determining what I need to buy on the PC side: access point, network adapter, wireless network card??
What do you think is the best/cheapest option?
Thanks,
Camed
i think that access points i'm not 100 sure cant connect to other devics and only be connected to from others
and i'm not really sure what you mean the difference between these 2 options are unless you mean network adapter to connect to the access point
" network adapter, wireless network card"
If you should choose to buy an access point, go for a AP with router funtionality.
The price is (should be) allmost the same..
This will allow you to share your broadband (if you got one) connection with both your XDA and your PC.
The phone via standard TP cable (or WLAN), and the phone through WLAN.
The way these will interact with each other, is just like two computers in a network (TCP/IP protocoll).
As for the network adapter and wireless card, these are the same thing..
The only difference is the way you connect them to your computer. (PCI, PCMCIA, USB, etc..)
With these you will be able to use Ad-Hoc, wich is just like a crossed TP cable between two computers.. Allso using the TCP/IP protocol..
As for price, a USB WLAN device should be the cheapest, at $30-$50..
The WLAN router is the most expencive component, priced from $100-$200 i guess..
DISCLAIMER: The prices are estimates! They may vary a lot! And they are based upon the 802.11g (54mbps) standard. 802.11b (11mbps) may be cheaper..
I have a wireless router (with 4 port lan) connected directly to my cable modem. It provides a lot of flexibility. For example, into the router I have plugged my main PC (upstairs), and a Bluetooth Access Point. Downstairs I use my wireless laptop and am able to be online through my broadband connection. I have an XDA II which does not have WiFi, but no matter, because I can use the bluetooth access point to get online. If any friends or family come with their PCs or Laptops, I just plug in either a wireless PCMCIA card into their laptops or a USB wireless adapter into their PCs and they too can get online. I also have a wireless printer server, which is great because I can print from any PC without the requirement of a different PC being logged in.
I can suggest you a bit more advanced solution, specially if you have dedicated internet channel with ethernet cabble on your side (e.g. ADSL modem with ethernet connector or even TP cabble going to you from provider): just buy gateway with access point built in.
An additional benefits of this approach are permanent internet availability via WiFi even if desctop PC is powered off and easy creation of secured SOHO (Small Office or Home Network) infrastructure.
There are a number of such devices. Most of them will provide you with similar functionality:
- one "WAN" ethernet port (where you connect twisted pair from your provider or ADSL);
- usually 4 "LAN" ports where you may connect all your home computers or just make network outlets in different rooms
- WiFi access point built in
- DHCP server for LAN clients headache'less connectivity, NAT server, Firewall (WAN to LAN, LAN to WAN, WLAN to LAN etc) with IP and URL filtering and different tunelling presets, DNS proxy and a lot of flexibility in creation of different virtual servers.
- almost all firewall settings may be scheduled allowing you to restrict the time your family wil play online games
- supports modern strong WiFi encryption and authorisation with WPA or WPA/SK protocols
For example I can suggest Asus WL 500g (which is I bought)
http://www.asuscom.ru/products/communication/wireless/wl-500g/overview.shtml
Cheap enough ($90), flexible, stylish and with number of additional features. With firmware sources available. Print server and FTP/Webcam server (optional)
But: 802.11b/g only, have no built-in battery for internal clock working while device is turned off. Internal clock are automatically sinchronized with external time server when it become available after power-on.
Or another solution, D-Link DI-784 (my office WiFi infrastructure based on this device):
-802.11 a/b/g
-have built-in AC-independent clock
-a bit more powerfull transiver
but more expensive ($200)
http://www.dlink.com/products/?pid=299
As I said above there are a number of such devices on the market, but I deal with these two only...
I have a Evo 4G with CM 7.1 I have used the built in app, but it will not work for my needs. I have looked and used android wifi tether for root users, but I don't think this will work either.
My set up would include a desktop (wired to router), laptop, wireless router, and phone.
What I would like to do is use my phone as a backup connection if my home internet goes down (which happens enough). But since all of my devices are not wireless I have an issue of connecting to the internet though the phone. So I am looking for an app that would allow me to share my phones internet though wifi, but instead of the phone becoming an AP. I would like it to connect to my wireless router. From there I would set up my default gateway to be my phones IP address which would route the packets to my phone. This way all of my pc's and internet enabled devices could have a data connection when my home internet is on the fritz. Now I know alot will say the phone will not have the bandwidth to support that many devices, but I will disagree becuase in my testing I have got 1.7down .7up consistent on my phone which beats my awful home internet at 1.5down and .5up.

I don't see how this will work for me... I want to turn on tethering and connect my phone to a wireless router and then connect my computers to the wireless router also. The router would hand out ip and would set the default gateway to the ip of the phone.
Could you use an app that allows you to tether using USB and connect a usb from the phone to the router?
I was using the barnacle app to wireless tether when I had cm7, but not using a USB.
Is there a script or app or ROM that will enable Ad hoc network connectivity with WEP security?
In my classroom I have a mac sharing its wired connection over its wireless card - instant wi-fi. Until recently it has been unsecured and I connected my phone to the network via wi-fi.
Recently I've had to add a WEP password as students have discovered the SID. Now my Samsung won't connect. It sees it just fine but won't connect even with the password.
Please Advise how to make the connection.
Thx.
Aww man! No help on this?
To recap - I can see and join ad hoc wifi network when there is no WEP security in place. When I add a password then I can see the network and try to join the network, but when I enter the password nothing happens. It thinks for a while and then it disconnects.
Any solutions? Or recommendations about what would be the correct forum to ask in?
Sounds weird, as our phones don't normally support connecting to ad-hoc WiFi at all. The only ROM that does support it as far as I know is Alien ROM:
http://forum.xda-developers.com/showthread.php?t=1376482
I'm not sure how you managed to connect to ad-hoc in the first place, and if it's not ad-hoc then it should already support WEP out of the box.
I'm using the GingerSnap ROM: http://forum.xda-developers.com/showthread.php?t=1418293
FiveOhFox, the dev, doesn't mention anything about adding this functionality but I've used it every day (Until I added the WEP and password).
Maybe I'm using the term adhoc incorrectly. This is a Mac, wired to our network via CAT-5 whose wireless card has had internet sharing turned on. This broadcasts a SID and allows wireless clients to share its internet connection - with our without WEP.
To clarify first and foremost, I'm looking to tether Wifi to Wifi. Not Wifi to 3G as normal (aka FoxFi and such)
On the iPhone, there is the most popular tethering app MyWi for jailbroken users. It allowed you to tether in all kinds of ways.
You see, some devices cannot connect to my school's network over WiFi. But, my iPhone could so I would tether the WiFi connect to the WiFi hotspot so that devices like my Roku box or PS3/360 could connect to my iPhone to get internet from the school.
So basically,
School -> iPhone -> PS3/360/Roku
Passthrough WiFi
I miss this on my Android, and I see that when you use FoxFi - it turns off the WiFi connect to the school AP and only tethers to 3G/4G. I don't and can't really use that for something like gaming.
Anything like MyWi on the Android at all?

Only way I have been able to get WiFi passthrough is by plugging my Note 2 into a USB port on my PC or into my router if your router supports USB through 3G/WiFi
Hey all. So heres my deal. I have a Linksys E3000 router and an Edimax Wireless Extender I just picked up. I got this since in my house, the router is on one side of the house and so naturally, on the other side, I get 1 bar of wifi strength. Was hoping to improve that. So what I wanted to do was have both units have the same SSID and have the devices automatically switch between the physical devices (same SSID) as I get near them. This didnt work. In fact, both my S3 and my Nexus 7 kept getting confused and dropped connections often.
So now Im trying it where they have different SSIDs (lets say Router1 and Router2) so no conflicts. The issue I have is this. I want both my S3 and N7 to AUTO SWITCH to the better signal SSID. Im running Cyanogenmod 10.1 on both devices and I see in the adv wifi settings something about, 'Only connect to a network where strength is GOOD'. This seemed to be the answer, however it doesnt actually work. 1 network shows great and other shows fair and it still wont switch.
Wondering if there is any other way around this? Otherwise this extender is basically useless to me as I dont feel like constantly switching my wifi networks as I walk across the house. (wow I sound spoil when I say it like that lol)
Thanks all
Is it configured for Universal Repeater Mode?
When you say "it" are you referring to my router or the extender device?
The router BTW is a Linksys e3000 with dd-wrt and the other unit is edimax 7348rpn. I believe that's the right model. Its a little plugin unit. Thanks
