Android Cannot Connect to Proxy enabled Wifi - Galaxy Tab General

After searching and trying out several ways to connect my GT to my school's proxy authenticated wifi network I gave up. Then I thought about my ipod touch, registered my wifi mac address with the IT guys and voila it was so easy to configure proxy just my entering user name and password I I can surf.
Now why on earth did android neglect the proxy wifi I have no idea. Furthermore, the adhoc wifi does not also work OTB and will only work if rooted. Why?
I am beginning to regret purchasing android device.....

Hi, what is the specific problem-is it connecting ok to wireless but not authenticating to your web proxy server? apps like asproxy ( http://alsubang.github.com/ASProxy/index.html) should work, but haven't tried it myself....

I have tried asproxy and it did not work. And yes it connects to the usual hotspots like starbucks. I am also rooted so I am able to connect to adhoc from my nokia phone(joiku hotspot).
I also know some friends who have the 10.1 and the asus transformer and they also cannot connect to the schools proxy. A visit to the IT department confirmed that Android is not supported.
A lot of people in our community are already put off getting an android device because of this.

[Q] Connecting a ps3 to the internet through HTC Hero

I'm trying to connect my ps3 to the internet using my phones internet. I have a rooted Hero using wireless tether to my pc. I enabled internet sharing on that connection and hooked up an ethernet cat-6 from my ps3 to pc. My ps3 keeps timing out trying to optain an IP address. Does anyone know if it's possible to get the ps3 to share a mobile internet connection?
Edit: Manually entered IP address and it now successfully obtains, but I get a DNS Error. I've tried a few open source numbers, none of which seem to work.
Why don't you just Wi-Fi tether? Program like wifi barnicale tether
It works from my N1 to ps3 slim
I tried that first. My ps3 wouldn't pick up the network when it would scan. I read that ps3's can't pick up ad-hoc networks. Maybe the new slims have that added feature though?
Make sure you are using one of the latest versions of wifi tether (.09 or .10). I think they now are a true router rather than a ad hoc connection
Sent from my ADR6300 using XDA App
So I also have an HTC hero and what I'm wondering is if I can completely bypass using a pc/laptop and go directly from phone to console using a tether app ?

VPN on Vodafone UK

Hi All,
I successfully set up the VPN to access the network of the company I work for, mainly to check emails on the go (3G - Vodafone UK).
The VPN does connect, but when it comes to visit our internal website there is no way to make it work - the page just doesn't load (but VPN is still connected). Same thing for emails - I can't set up an email account (email server is in the private network).
Suggestions?
My colleague on iPhone (Vodafone) and Galaxy S (Orange) have no problems.
Thanks!
I have never managed to get pptp vpn to work on any android so I would love to hear of a solution. Vpn remains connected but no browsing possible. I have heard that on unencrypted vpns it works.

A long time ago - roughly 2.5 years I had trouble with Cisco ipsec vpn profiles on vodafone.
Basically they would never work on vodafones network but would work on t-mobile etc
After extensive research it turned out to be NAT related.
What I ended up doing was setting up the profiles on a server, enabling split tunnelling in the profile on the ASA and RDPing to the server then tunneling from there.
VPNs through a Virtual Machines on my laptop when using the phone in AP mode do now work though and have done for the last year.

Quick update:
The VPN actually works great over wi-fi. I can connect in a second and browse whatever I want. On 3G either doesn't work or it is really slow so that the page times out (hard to tell).
I am confused, is it device or network related?
I wouldn't like to touch the server, even because it works with iPhones on O2 and Vodafone itself! And Vodafone obviously is bouncing me to Samsung.
I suspect that the Galaxy Note has some sort of bottleneck somewhere.
Is dropping from H+ to 3G an issue when connecting on VPN?
I can connect successfully using vpn both to my work, and another site, both using PPTP vpns.

Ralphmartin,
Do you connect over mobile internet?
Which phone do you have?
Update for Vodafone customers on Android.
Ask Vodafone to activate the Mylan access point. The only downside is that you wont be able to use any internet beyond the VPN.
Annoying, but at least something.

Q: Set up a local network between S2 and a Laptop?

Hello,
I am running a local web server on the laptop and want to phone to connect to that through a web page.
Would this be possible? Is there a way for them to network interface like this?
Thanks
Chris
Hmm I'm still kinda confused as to what your wanting but try this. Connect your phone to the network via WiFi and point your web browser on your phone to the web servers local IP. If this doesn't work add me at "[email protected]" and I'll assist you further

Hi X,
Yeah I have discovered I'll need the router for the DHCP assignment so they can communicate.
What I was throwing around was using tether to make a network between the two but without the DHCP server to assign an ip I can't see how its a viable way to communicate.
Thanks again
Ah I assumed you had a router. But yea that's all you will need and your set

[Q] VPN over wifi Internet doesn't work for some reason

I am able to connect to my home router's PPTP VPN server from my Android phone's PPTP client. I can even see my remote LAN devices; and, my remote LAN devices can see my mobile phone on the LAN.
The problem is when I connect my phone to wifi Internet.... BEFORE connecting to my PPTP VPN server... I can't see the remote LAN; and, the remote LAN can't see my phone. The only thing I can do successfully is get a new public IP (my home Internet public IP).
What can I do so that I am able to use my local wifi Internet connection to connect to my VPN at home?
It might be a route problem.
When you connect to WiFi, some static routes are pushed to your phone.
Those routes might not be refreshed or conserved after a VPN connection.
If it is not a route problem it's a default gateway problem.
Yes, that's what I suspected. I already tried adding routes; specifying the gateway via command-line; however, I didn't have any luck; probably because I didn't know exactly what I was doing.
One thing I noticed; when I use my wifi internet hotspot, I noticed that it gets a private WAN IP.. 10.x.x.x; which then NATs to a temporary real public IP; which no connections instigated from the outside world can make it So, even if I do port-fowarding on my wifi hotspot router, it doesnt help any since the incoming connections are stopped dead in their tracks.
I'm using PPTP VPN; which depends on a TCP port 1723. If that TCP connection is instigated from my remote VPN server into my mobile Internet wifi hotspot based LAN devices, it wouldn't work for the same reason explained above. I didn't see a PPTP VPN passthrough option for my wifi hotspot; only for IPSEC; which I dont have a server for. I'm guessing that if I had a real-world public WAN IP for my mobile Internet hotspot, maybe I wouldn't have this problem for PPTP.??

First, are you talking about a free internet hotspot or from private internet hotspot (@work for example) ?
you'll never gonna get a public IP from your internet hotspot. 1-public-IP-for-1-client on a hotspot is just inconceivable, due to IPv4 exhaustion.
I think you only have to try to do port forwarding on your hotspot.
Your assumption "it doesnt help any since the incoming connections are stopped dead in their tracks" is wrong I guess. If your hotspot has a built-in firewall, it might be stateful. As you are initiating a connection to your server, the returned traffic flow shall be allowed.
If it doesn't work after port forwarding, try to look at firewall rules on your hotspot router.
Problem resolved.
My Verizon wireless hotspot (890L) doesn't support PPTP passthough. More specifically, PPTP's routing protocol: GRE (value 47). Verizon does offer another wireless hotspot that does offer support for PPTP; at least via a firmware update.
This issue actually pushed me to install and configure OpenVPN server on my router; instead of using the existing PPTP server which I already had. OpenVPN is fantastic is working through firewalls.
Great !
Yes, OpenVPN is a delight.
me too
I have the same problem,
but I usually change another ROM until there's no bugs

have you tried to configure the wi-fi gateway to match your vpn router?
settings / wireless & networks / wi-fi / long press your vpn connection / modify network / scroll to show advanced options / select static ip /scroll down to gateway and put the gate address in / save
I run a vpn through a 2 router setup, and even though my phone connects to the vpn router, its gateway by default is always the non-vpn router. changing the gateway to the vpn router allows the vpn to connect to the phone. you can verify the vpn connection by going to ip-score.
That why i can't see my phone using wifi in VPN network..
cant connect if theres no mobile data or load
Hi please help ..when i have load i see its connected..but if i have no load its not connecting please ..anyone can explain this?

(Solved) [Q] Android devices connects to wifi but no internet

I have three Android devices and two laptops, all of which I have been using on my home wifi network for years with only minor issues now and again. All of which I have been able to resolve. Two of the Android devices are phones and are rooted with custom roms and one is an unrooted Nexus 7.
Sunday, the 6th of April (yesterday) all 3 of the Android devices lost internet connectivity spontaneously but both laptops still access the internet with no problems over wifi. I was not doing anything with the network or any of the 3 devices. The Android devices all still connect to the wifi and they can all access all the other devices on the home network. I can ping my phone from my laptop and I can ping my laptop from the phone. I can access the files on my phone using AirDroid. I have reset every device on the network including the wifi access point and the cable modem. I called my ISP and they are saying that it might be due to the fact that my cable modem has reached "End of Life" and does not support newer Docsis 3.0 technology which for some reason now precludes Android devices from accessing the internet. I don't buy it. I read up briefly on Docsis 3.0 and it is supposed to be backward compatible with Docsis 1.0 and 2.0. I have not had a chance to see if my phone or the other devices will connect to the internet through other wifi networks but I suspect they will. My phone does connect through the 3g network.
Anybody having this issue and if so have you found a fix? My only solution at this point is to buy a newer cable modem that supports Docsis 3.0. It's not all that expensive but I don't want to buy one if I can't confirm that is the problem. The one I have seems to be working fine with the laptops and was working fine with the Android devices before it quit working. If that is the problem.
If anybody has any suggestions as to how I might test this I would be grateful.
Do you have a terminal app? Start pinging your router then 8.8.8.8. Then if you can ping Google, then it is something else.

Dude, you nailed it. I pinged google and that didn't work and when I pinged the IP it worked. I also was able to ping that 8.8.8.8 ip. I knew then it had to be a DNS issue.
I then set my IP on the phone to static and then I used the Google dns server IPs 8.8.8.8 and 8.8.4.4 as my DNS servers and Bingo, it worked. Why was it working before? What changed overnight? And why did it occur to all three Android devices at the same time. Up until now I had been using DHCP and everything worked fine. I even went for a walk around the block and found a couple of unsecured wifi networks and connected to them and subsequently the internet. But when I got home and connected to my network, no joy. However, as stated in the OP, our wireless laptops work just fine. Maybe Comcast is sending out the wrong DNS IP or they just somehow no longer support Android???

I am having this exact same problem. My laptop connects to wifi and my desktop, ps3, and TV via Ethernet but all of a sudden about an hour ago my Nexus 5 and Nexus 7 can no longer access the internet. They are connected to the network however the signal indicators in the quick settings is orange and I can't access the internet.
Could you tell me exactly what you did to fix this as I am not good with networking type stuff at all...you mention pinging and DNS servers and I have no clue what you're talking about.
BTW I have AT&T U-Verse.
EDIT: I ping'd google in my phones terminal and it didn't work....I ping'd my router and that worked(I think it did anyway...it kept pinging and I had to close terminal to stop it)
I ping'd 8.8.8.8 and got Destination Net Unreachable.

I don't know what AT&T U-Verse is but the problem I had was that for some reason my Android devices would no longer access anything outside my home network. I used a terminal app that I have on my phone and I was able to ping 8.8.8.8 which I understand is one of Google's DNS servers. DNS stands for (Domain Name Service) which allows us humans to type in meaningful names in a browser rather than the IP address. If you can enter this http://74.125.224.72/ into your browser on your Android device you should get to Google. If that works then you need to point your device to a DNS other than the one assigned by your ISP. I just used 8.8.8.8 and that solved my problem. You can also change the DNS server in your gateway device, whatever it happens to be, and that would fix the problem as well. That is assuming you can reach Google using the IP address I have mentioned previously.
There should be all sorts of tutorials and suggestions regarding how you can make the necessary changes. It all depends on your device and network appliances.
