Hello,
I am using gueste rom with spica kernel, but I think it is independent of rom/kernel.
When I have internet on 3G on my o2x, I connect it to my laptop and use usbtethering. It works.
When I have internet on wifi on my o2x, I do the same thing but I don't have internet on my laptop.
Wireshark shows that my laptop send packet through my phone and I can ping my phone. But I can't ping website. However dns works (I can see dns packet). On my phone, internet works well.
I don't really know how does tethering work. Maybe it uses iptables/nat ? How can I have working tethering? Thank you.
What WiFi device is your phone connected to and why can't your laptop just connect direct to that? (I'm assuming the laptop has wifi). It's also possible to set your phone up as a WiFi Access Point, that would allow you to connect your laptop wirelessly. As I understand, however, if you use your phone as an Access Point, it won't be able to connect to the internet via WiFi - eg, you could be in field with good 3G, connect your laptop via WiFi to the phone and then surf via WiFi and out via the phone's 3G signal.
The author of Gueste does warn about using spica's "performance packs" for stability issues.

It is a public wifi emitted by a router. It is possible that the router blocks tethering?

I could, the reason is that my wifi signal is weak but at my door. It is just more convenient that my phone is near my door and connected to my laptop. Moreover, I'm studying networks and this issue arouses my curiosity

So my laptops internal wireless card gave out, and while I don't mind using 3g.. wifi is a little faster, so is there a way to use that instead of 3g? I do not see it as an option in the internet sharing app.
thanks
hmm, i think ICS could do that.......... connect via wifi then connect ICS with USB or bluetooth..... hmm, i was thinking wmwifirouter could do it but i am not sure
already tried that. I think that wmwifirouter is for sharing 3g over wireless
simple..I do that all the time.
Turn off Data Connection
Turn On WiFi
Turn On Internet Sharing
..wah-la !
i tried that but under network connection wifi does not appear and it tries to connect to 3g?
I know we can simply connect my HTC via my wireless connection,
but is there a way, presumeably if we want to connect our phone
to the internet via PC. anyone care to share the tricks? thx.
I can't get AirDroid to connect using ICS leak 213.
I can't even get my phone to respond to a ping from my laptop on the same network, though I can ping my laptop from my phone on the same network.
Any ideas?

It sounds more like a network/router issue than an AirDroid issue, it worked fine for me in .213 and .215 leaks.
Is your phone on a VPN connection? If yes, then it's possible that your phone has multiple IP addresses and AirDroid is showing one which is not accessible from your laptop.
Did you try both connection methods? Via the local IP and via the AirDroid.com wensite?
No VPN connection.
I tried both by local IP and web.airdroid.com, and checked that the local IP is correct from both About>Status and my router.
If I try to connect just through Chrome, I never get anything. If I try to connect by scanning the QR code through my phone, I can sometimes get it to connect initially and bring my to the AirDroid desktop, but I almost always can't access contacts, messages, etc.
I tried port forwarding 8888 for my local IP, but that didn't seem to make any difference.
The strange thing is that my Touchpad works fine with AirDroid. In the past, I've had some odd Wifi issues with both my Droid 4 and my Droid 3, e.g. adding an Exchange account won't complete setup if I'm using wifi on either of those phones (on GB and ICS), but it has worked fine on Android devices without cellular radios (my Touchpad and Archos 101).
It appears like it's a network/router issue, but at the same time appears like it's not.

There could be a clue right here. Do you have a mobile data subscription?
If yes, then perhaps there are some very small WiFi drops which cause Android to try to connect to mobile data instead of WiFi, and the time it spends without the local IP might just be enough to impact AirDroid performance.
You could try the following:
Put the phone in Airplane Mode to disable all wireless connections
Manually enable WiFi - this is possible without disabling Airplane Mode
Now you are on a pure WiFi connection, no mobile data or Bluetooth PAN to interfere. Does that improve AirDroid's behaviour?
Also, if you know how your router works, you can give the Droid 4 a fixed IP address to avoid the IP changing when there is any network hiccup. Most modern routers usually seem to remember which IP they assigned to a device via DHCP anyway (at least for a limited amount of time) but it's worth a shot.
No such luck with the Airplane Mode/Wifi. I outright turning the cell radio off with Phone Info too, still didn't work.
With DD-WRT, my router will keep IPs and MACs associated, so it's not that the IP is changing.
If I reboot the phone, it'll work a little bit initially but eventually stop working and I won't be able to ping it either.
Good Morning!
I'm use Rom GingerDX v28b and have one problem.
My Cell phone not connects to network AD-HOC,she is created by the my laptop...
Symptoms cell phone, he gets to connect network, but can't to surf the internet, and if I connect it to a network managed by a normal wifi wireless Robe and it connects normally and navigates ...

There are 2 types of adhoc network. One with shared ip and the other with static ip.
Which are you using? Shared ip should always work.
Your settings are probably wrong on your phone.
Well I been helping my sick aunt and she doesn't have WiFi and my phone does not have service so I depend on WiFi. Well I tried to create an adhoc network and my phone sees the network but can't connect. I have heard tell that adhoc is not able to be connected too but searching around has not found an exact result. I have the CyanogenMod Mod 10.2 android 4.3.1 on my phone. I did see something about a WPA supplement fix. Is there a fix for this and if so how. Would be great to be put on the proper course. And I did search. But I didn't find a thread regarding this.

When you say you created an ad-hoc network, do you mean you are trying to have a laptop that is connected to a wired network broadcast its wi-fi so your phone can connect by wi-fi to the laptop (and thus the internet)?

Used my dlink dwa-130 USB dongle to create an adhoc network on a desktop computer. The desktop has a satellite connection. I was trying to share the connection from the desktop over the adhoc network to my phone with internet connection sharing. But my phone can't connect to the network but sees the security type and ssid.
Hi !
I have a S21 Ultra, and use it as a modem for my house with wifi tethering.
I can access my printer with my computer on this wifi network
But here is the problem : I can't access the device on this network from my phone.
I can't print from my phone,
I can't use app mirroring on Windows (open samsung flagship apps on W10 computer) because both S21 and computer have to be on the same wifi network.
Is there any way to make the phone part of his own wifi tethering ? Or workaround ?
Thanks !
no what your trying to do is hack someones phone....its not gonna happen!!!!

Don't understand your message... It's my own phone that doesn't detect itself in the wifi network list. I have no problem to connect network from one phone onto another. It is on the same phone, both emitter and receiver

I think you can try to make a hotspot on the PC and share wifi (from the phone) to the PC hotspot and connect the printer itself to the PC hotspot
Tethering is like connecting a modem to a device. Hotspot is creating a local wifi network for devices to connect to.
Tethering vs Hotspot: Difference and Comparison
Tethering allows a device to share its internet connection with other devices via a physical connection (such as USB), while a hotspot creates a Wi-Fi network to share the device's internet connection wirelessly.
askanydifference.com
Based on your description you are creating a hotspot on the phone that the laptop and printer connect to? If so then the phone cannot "join" that network as the wifi stack in the phone is being used to run a network and the phone has access to the mobile data network the wifi is representing.
No, only the computer connects to the phone.
but create a second hotspot on the computer that connects the printer to the computer

Your phone wifi module can either act as a broadcaster or receiver at a time, but not both. It will only handle one wifi network at a time, either the one it's broadcasting (endogenous mobile hotspot) or the one it's receiving (exogenous WiFi)
You can see this as a prompt when you turn on mobile hotspot. Whenever you turn on Wifi Hotspot, your WiFi will automatically get turned off. It will even display a notification and ask for your consent (at least mine does)

Wow! That's nice to hear. Haven't used that feature on a phone before. Didn't know it was doable. Well, I guess you learn something new everyday.
thats what hackers and LEA use.....smh
