Why do some websites show up when using wifi but not GPRS/3G?

Hey y'all,
I tried to search for the answer to this but couldn't find anything. Basically, I have found certain websites (my company's webmail, for example) that show up fine when I'm on a wifi connection, but come in blank when I'm using a GPRS/HSPDA connection. I'm guessing it's either a proxy setting or a Pocket IE registry setting that is causing this, but I have nothing really to back that guess. Is there anything that can be done to let me see the websites on both connections?

When you connect to WiFi, are you at home or at work? Is it possible you are trying to connect to a site that can only be reached via the "privileged" WiFi connection you are using?

If you can connect via WiFi and not via phone...
a) You do not have the correct Carrier data profile connections installed for GPRS.
b) You have re-flashed you rom and suffered a)....!!!
c) You have lost data links and java access to sites. Install Java, or re-flash your operator and stick with the cheap option you purchased!!!
d) Check for the network setup wizard (on this forum) and go to your carriers website to check the settings.

Thanks for the replies guys...
@dunneldeen: that's a good thought, unfortunately it doesn't seem to be limited on which wifi connection - in other words, I can connect regardless of the wifi area (airport, home, coffee shop, etc.) so that's not the problem.
@Farsquidge: I'm not sure if I'm understanding right. I can hit most websites and see them fine over GPRS, just a few certain ones don't show up - thus, I don't think it's my carrier settings. Option C seems like a potential candidate, I'll try installing Java and see what happens, and I'll report back if successful.
Thanks!

Err. Please don't forget you are using 'Pocket IE' not full blown IE and it will report that back via cookie to whatever site you are on and they will send you the cut-down version.
Download the trial for Opera (Not the mini version) for Windows Mobile.
In it's setup you can set it to report as PC.

Yeah, I figured it was a Pocket IE problem. It just seems strange that it works on wifi fine but not GPRS: does it send different cookies thru wifi than GPRS?

Err.. Actually, ya caught me out there but hopefully I can go back to my previous post and say you have lost your carrier profile for net access!

Can you access the internet when connected via ActiveSync?

With my trusty old Ipaq 5550 i could, but for some reason i cant with my Kaiser.
I had a look in the manual but couldnt find this.
Any tips?

It should work automatically.
Perhaps in your comm manager, active sync is greyed out and needs to be enabled.
Or perhaps in your configuration screen: connections tab, usb on pc (or sometinglike that), you can (un)check a box about advanced network connectivity.

yes for me work You must change in Connections->Advanced->Select network first field where you have your ISP to My Work Network.

EXACTLY.
Mine was checked, once i UNchecked it. I had internet conectivity.

I have all default and CHECKED use advanced network functionality and it works fine, even when syncing over bluetooth I can get to the internet through ActiveSync

Thanks, been wanting to do this for ages.
Now I have got it working.

Okay, this is a long message but I have had a unique problem in which I had to fiddle with activesync and my PDA for several days to figure it out. So in case this is your problem look here.
Scenario:
At my work we have a proxy server. When i connect my phone to my computer, even though activesync and my PDA are set to connect properly neither my phone nor my computers internet works. I fooled with this, posted on the forums and finally found a way to fix it.
Steps:
1)Change your PDA's advanced network settings in the network management area to BOTH be "mywork network". Do this before plugging in to activesync.
2)load an internet page with streaming content, or constantly refresh a web page if your work blocks all sites!
3)Ensure that your activesync is set to connect to the "work network".
4)Plug in your phone (be sure that data is still streaming on your desktop, if an active connection isn't streaming on your desktop Windows uses logarithms to decide which connection to use as an internet source).
5)Let activesync load and syncronize. Once it is syncronized, go back to your pda's network management page and change the two options BACK to MEdia Net or whatever data service you use on your cell phone. NOTE: Be sure that media is streaming all the way until you change your PDA's options BACK to the proper internet source for your phone and test it by loading a web page. Once the phone is set as it's own internet source and the desktop still has it's active LAN connection you should be golden.
I know you shouldn't have to do this but at least with my works network and their proxy server if i don't do it this way i will NEVER be able to use the internet on either device.
The reason for this is because of Microsoft's crappy network capabilities. In activesync 4.0 + they made activesync use an actual network connection, you can view it via the network connection page. So with some networks (not all) it tries to use your phones connection as the active internet network and vice versa at times.
Hope this helps somebody out there as this drove me nuts!
So far i'm the only person that has had the problem (on this forum, at least that has responded to my threads). But i'm sure there are a couple other people that have annoying problems with their work and activesync.
Thanks,
Luke

Thanks a lot alaiwy, worked just fine for me!

For the AT&T Tilt & AT&T ROM's you also need to disable the Proxy.

At Work- Access network via ActiveSync/USB?

I read somewhere that when hooked up to the PC and activesynch, that WIFI doens't work (which seems to be the case for me) and you can/will access the internet via that method. The trick is you need to have the proxy server that your office uses entered.
I have ooked to my PC at work, and have the Proxy address in, but I still cannot get to the internet.
The one thing that I also seem to remember (can't find that post now) is that somethign about Active synch. I just tried, on the PC, to select "This computer connected to The Internet". It had been auto. didn't help.
Am I trying to do somethign that I can't? If not, any ideas you can share on what I need to set up?

You can allow your phone to use WiFi by checking the box in your ActiveSync settings.

Thanks. That wasn't really what I need to know. I need dto be more clear.
I don't have wifi at work (well I do, but after many attempts and a long thread here, I still cannot connect to it).
What I want to know is can I get to the internet through my hookup to my computer.

You will have to speak to your network administrator.
They could be using MAC addressing or simple password access to a proxy. Either will prevent you using the PC's internet access.
You may also find if they do allow you Internet access, any SMTP or apps that use specific ports/protocols may not work.
It's most likely just security at your work establishment!
EDIT: One way I found around it in MAC systems is to add an access point to your PC which can the copy the PC's MAC to itself and use NAT so that the network just thinks its the PC communicating (you will need another NIC in the PC). The Activesync connection does not use NAT in a correct fashion.

this should help, if you cannot view pages @ pda via AS

Accessing the proxy at work with a PC is as simple as entering the dns name in my browser setup on the PC. I an accessing it fine wiht that. IN fact they have the wireless set up so that anyone coming in visiting who is told the proxy dns name can access a 'public' wireless method. But for some reasong my Tilt will not work on either the public one or the private one which is using Peap.
I also find that at home where I know all my network setup I cannot access the Internet via hookup to the computer.
Based on all of that it must be somethign about my Tilt, or more likely, the setup.
BTW...I can access wifi at home and many other places. Just not through the USB and PC or wireless at my work place.
Pulka...I'll check out your item.
Thanks
[edit]
I just re-read Farsquidges post, and that may be something to check out at work. And I know tha tat home, my router is set up to allow specific MACS. I don't think they do that at work. but I'll see if I can get through it at home. My router will display the MACs trying to get through, and I can allow it. At least that will answer if my Tilt is even trying to get through maybe.
[edit 2]
I think I must not know how to set this up to access via the PC. I just attempted at home, and my device seemed set up for Work Network. I'll have to figure this out.

Connection trouble with BB Connect on HTC FUZE

I installed BB Connect .106 onto my HTC FUZE and actually got it working, new PIN, IP address, everything seemed fine.
BUT. . .
I found that I could not connect to the internet or get emails, even though the connection settings clearly showed me as being connected to Media Net.
Has anyone else had this problem? If so, is there a workable solution? FWIW, I do acually have a Blackberry plan (BIS) in use with my Bold, but I would like to have the option to switch between the devices as I wish.a

What, no one??? No one at all???

I am using about the same config as you, but all is working fine here. Keep in mind:
1. You have to set up a correct connection (APN) for all internet traffic but BBC (which uses its own non-configurable APN)
2. When you click on an internet link in a Blackberry message, your browser tries to use the BBC set APN to get the page.
3. When you browse to an URL in IE or Opera your browser tries to use the (self set) internet conection APN.
Maybe this helps you solve your problem.

Thanks for the reply. When I have more time to experiment I'll check it out.

[Q] VPN issues

Hi All,
I am having issues when trying to connect to my work VPN. I need VPN access in order to check my work email and browse an internal website.
Now, the VPN always connects, either on 3G (in UK) and wifi.
However, even if it says "connected", I am not able to download emails orbrowse the intranet unless when connected to my home wifi and sometimes on mobile internet.
If connected through other wifi networks (recently tried on a hotel free wifi, in the states and on a private home network, in Croatia), the connection itself seems to go through some sort of bottleneck, and no emails or browsing is then available.
I am blaming the phone itself, since my colleague had no problems whatsoever on his iPhone.
I am on Galaxy Note, non rooted, Vodafone UK.
Please help, this issue is making my Galaxy Note almost useless.

just FYI I'm also on UK Vodafone and I can connect fine with openVPN to my home network ... tested on 2G,3G/H+ and also on various public & private WiFi networks - always connects fine, only issue I have is that my server .ovpn tells the phone to use my home router as it's default gateway (so that I can browse securely on public wifi). This doesn't work out of the box - I need to use the openVPN app's "fix DNS" option.

errr ... I'm an android noob, but AFAIK you need root for openVPN to work? I never tried running openVPN on my note BEFORE I rooted it, but anything I've ever read says root is required?

What APN do you use?
I have to switch everytime to something called MyLan to connect over 3G.
I am using the stock VPN client, did not adventure myself into OpenVPN. Would that work with an encrypted VPN?

Ah, sorry - I somehow managed to read the thread title "[Q] VPN issues" as "OpenVPN issues" .. case of my eyes seeing what they wanted to rather than than what was actually there. You are of course right, the stock VPN options don't need root (and of course openVPN client will only work to talk to an openVPN server).
I did set up a PPTP server on my WinXP home machine and tested that with the note's inbuilt PPTP VPN client - it worked OK although I needed to turn off encryption, and I didn't do anything with it beyond just connecting as I was only dong it out of interest.
re. the APN - I don't actually know where to see that on the note (noob, as I said!) - when I do settings->wireless & network-> mobile networks, which claims to allow setting APN's, there is no info or settings re. the APN other than the "network mode" and "network operators" items, neither of which seem to show the APN used for vodafone data access.
Anyway, sorry for the bum steer, hope you get it sorted

Oh, never mind
Under mobile networks you have to go under Access Point Names, but most likely you will only have one APN, which is the regular from Vodafone.
So most likely is the encryption causing problems?

D'oh ... I thought that was a heading, didn't realise it was a clickable item! my APN is wap.vodafone.co.uk (APN type is "internet+mms").
IDK if encryption is anything to do with your issues ... I doubt it if you can consistantly connect from home wifi and sometimes from 3G - if encryption were the problem I'd imagine it would consistantly connect (or not) rather than be variable.
Maybe worth trying to ping your internal mail/intranet servers when connected and then talking to your work IT guys in case there are firewall/routing settings that you are somehow falling foul of?

Yes we are doing that, however that fact that iPhones can connect really makes me wonder!

Thread Moved To Q&A​
This is a question, and as such belongs in the Q&A Section​

there are lots of third party vpn tools and free available you can use those

Wilsonj,
Can you please suggest one third party vpn tools that works well on PPTP, with encryption?
I am not looking at OpenVPN, since it doesn't suit my needs.
Thanks!
