HI there,
Has anyone experienced an issue whereby bluefire or similar contivity VPN client connects seamlessly over WIFI and 3G however will only allow RDP or VNC over WIFI.
I am currently running bluefire and am able to authenticate through 3G but thats it, I have no other functionality.
Any help would be great!
Thx
I've seen it where specific ports are blocked on the 3G providers network, but given that you're establishing a vpn tunnel, that should be irrelevent, as all the traffic should be tunneled via the VPN. I wonder if the Device isn't picking up the new route to send the traffic via the VPN, and is instead sending it via the 3g connection to a non-existant device.
Does your VPN-endpoint give you any logs to show if its actually receiving the traffic from the device? Are you able to ping anything within the remote network (assuming ping is allowed) from the device?
One thing I have noticed is that if you have a 3G connection open, then establish a wifi connection, the routing table doesn't seem to update to use the wifi connection and you actually have to kill the 3G session. I wonder if something like that is happening here - the 3g session establishes a default route, the VPN session then comes up but the device doesn't realise to send traffic via the VPN session. Or are you getting any traffic through the 3G/VPN connection?
I have the option to turn on verbose logging. I ll give that a go and see if it highlights anything really obvious.
A picture is better than 1000 words.
For an application I'm trying to get this configuration working:
Is this possible or not?
WiFi Tethering to a WiFi Router / Network
Yes, IF your wifi router will accept wifi as an input.
If all of the devices need to be on a network OTHER than your cell phone, then yes, you need a router. The router will have to accept wifi as it's source.
If all of the devices can be on the same wifi network as your cell, then you can get a wifi repeater or range extender. Repeaters "extend" the range that wifi will reach. I don't see that as an issue here as should be able to place your cell phone well within range of your other wifi-enabled devices.
I don't immediately see why you can't have all of the devices connect to your phone directly, but I don't know anything about the application you are working on.
What I cannot say is whether this setup could bypass the number of wifi devices your service provider limits you to. I know my hotspot (Verizon) limits you to five concurrent.
I hope I've answered your question and I've helped. BTW - your picture was perfect!
Thank you for your explanation.
This is a very specific setup.
The router is an Airlink NMini and I carry in my pocket. It has to be near my camera for the wifi connection to work. I get a lot of interference from wireless equipment on my photoshoots. The Wifi router is trong enough to overpower the interference (only when used in B-mode). It's hooked up to a 5 volt power pack.
Close to me I have an Android tablet for quick selecting the right images, then the images are copied over to a remote laptop that is used by my colleage to edit the images.
I needed the internet connection for sending the processed images to a ftp server or dropbox, so my clients can download the images.
I tried using the router as a relay/bridge, but couldn't get that to work. Maybe it's possible, but that's higher networking config.
I finally got it to work by connecting the phone to the laptop using usb.
Configured the laptop for ICS connecting the USB-internet connection to the wireless router. Had to set ip adresses manually, becaue the dhcp of the router did not transmit the correct gateway. But as there are only 2 devices attached, that's not a problem after documenting this change.
So I'm good to go for our next photo assigment. Case closed.

Sweet setup man
Hello, been a long time reader from my G1 to my G2 and now my nexus 4.
I am unfortunately not able to use my device on certain wifi networks which is a real bummer.
Being that i have a background in diagnosing computer problems in my real world life, i thought i would post my findings as i found some interesting things!
First i will say that the network i will use as the demonstration is secured with WPA2 PSK AES security and encryption.
I can connect to it and often find i have problems on the first connect to the network. By this i mean if i have made my wifi settings 'forget the network' and then try to connect again.
On the first time it seems to indefinitely hang, showing the message 'authenticating' on screen next to the network and if i long press on the network name and press modify, the dialog shows that i have a link speed of 1mbps.
I can usually get past this by turning wifi off and on and then reconnecting, at which point it will connect straight away and have a normal link speed. (in this example 72mbps).
After i am connected, i find that the following does not load:
-browsing webpages through chrome does not load
-the wifi icon turns grey
-play store cannot load anything
I find that i get assigned an ip address by dhcp correctly too with the right gateway and dns.
I decided to download a network tool to have a better look. I use fing personally.
I found it very interesting what i found, which no other threads about wifi issues mention.
Network discovery found every device on the local wifi network.
I was able to scan the services of my computer which is also on the network and it found everything, including a http server which i run which i could browse to.
In fact i could do everything through wifi with this device and most others.
Again it got interesting when I then took a look at my gateway, the router.
I had discovered its mac address which i can verify through my computer is correct which to my understanding, being that i can communicate through the wifi, means that i have the information available to send information to that physical device?
When trying to scan services, i find nothing, which is not true, at the very least it exposes a http server on port 80 which my computer can access.
When trying to ping i have 100% packet loss.
So at this point it is only the gateway i cannot access.
So i figure i could setup another computer which is connected to the network with a wire to share its connection through wifi onto that network and then i have a standin gateway?
I connected this computer through wifi to the network and pinged it succesfully with my phone. I then turn ICS on my wired adaptor to share to my wifi adaptor. I ensure that the wifi maintains an ip address in the right range and subnet.
I then try to ping that ip with the phone and it then gets 100% packet loss.
Could this be that when a device is configured to act as a gateway something changes about how it handles any packets sent to it that the nexus 4 is currently in compatible with?

I have found a bit of a workaround that i can use!
When i said i turned on the wifi and ICS i did the following:
-Turned on wifi.
-Connected to wifi network.
-Turned on ICS on my wired network to share to my wifi
-Observed that my ip changed from 192.168.10.x to 192.168.137.1 with no gateway or dns.
-I decided to change my ip on the wireless to 192.168.10.x and gateway to my router 192.168.10.10
-I then tested.
I ran through this again but slightly different:
-Turned on wifi.
-Connected to wifi network.
-Turned on ICS on my wired network to share to my wifi
-Observed that my ip changed from 192.168.10.x to 192.168.137.1 with no gateway or dns.
-I decided to change my ip on the phone to 192.168.137.5 with gateway and dns as 192.168.137.1
-I then tested. And it works!
I know this doesnt fix the wifi issue itself, but for me, this makes a big difference as i can now use wifi at work where we also have poor mobile network coverage.
Edit:
Additionally i previously tried to setup this same computer to host a wifi network to share the connection using 'netsh' and creating a 'hostednetwork' but i found i was in the same situation where i still couldnt get the internet.
Hi!
I have an Indian Tablet called penta T-pad, and I have problems connecting with Tp-link Td-W8901G router. The First one is that the tablet doesn't connect instantly to the router using Wi-Fi . it shows in the Wi-Fi network list that the Wi-Fi access point is "saved, secured with WAP/WAP2", And it doesn't connect until I tried several times and when it connected (this is the second problem) it sometimes doesn't send or receive and data. And I have tried resetting the tablet and the router and changing the broadcast channels and use static IP... But, this doesn't work.
By the way, other devices (smart phones, laptops...) can connect to the router without problems, and my tablet was working well during the last six months connecting to the same router. And now, it can connect to other routers or access points (i.e. portable Wi-Fi hotspot).
Thanks in advance, I am looking forward to your replays.

You mentioned you are using WAP/WAP2 for security, but have you entered the password or entered it correctly?
Does your router have the ability to add users?
If so, then activate this option and enter the MAC for every device you need to grant access through.

No other information on actual WiFi setups were able to be located. I wish I could be of more assistance.
Hi I have very similar problems with my devices!
I noticed it is extremely popular problem being discussed everywhere, but no general solution is ready yet, neither straight way of diagnostic...
Only some particular solutions sometimes appear, but they are for particular cases, usually involving deep and accurate adjustment and "pairing" of gadget and equipment.
It would be good to know any general tips like where to look for any info about the wifi connecting process, what are the possible reasons to fail to connect when the signal is high, wifi is visible, password is 100% correct, etc.
Perhaps we can find the log of wifi connecting process, switch it to debug mode, show to experts?
Please, experts, we are all waiting for your replies!
I recently bought a new Asus router that allows me to use it as an Open VPN server.
Installed the Open VPN GUI/Apps on both Windows and Android devices, and both platforms were giving me full access to my Home network.
However, while the Windows devices still work 100%, all my Android devices are now barred from entering my Home network (though they allow general internet access through the server just fine).
Any ideas what's gone wrong on the Android side of things?
Thanks.
How are you connecting to your VPN server? Are your Android devices connected via wifi etc or are they using cellular networks to connect via your WAN
It sounds to me like a routing issue, for example your local network could be 192.168.1.0 and your VPN 10.0.0.1, so if your android device is connected via the 10. network unless routed it wouldn't know how to access your 192 network.
This seems like a similar issue, maybe you can find more help here: https://forums.openvpn.net/viewtopic.php?t=21311
Thanks for the reply, which I've only just had a chance to look at.
I can't get inside my network by neither cellular or wifi.
I'll have a good look at the link you've posted and report back.
I'm very much a network newbie and this has been very frustrating as it worked when I first set it up and now it doesn't, in spite of router factory resets.
