I have a Galaxy S3 that will not connect to my Exchange 2010 server using ActiveSync. The phone is an ATT GS3, v 4.1.1 Jelly Bean. I have troubleshooted and found out it works over an Outside WIFI connection (not internal company network wifi), but does not work over the mobile network 4g. I have tried clearing the cache, rebooting, and using different credentials but I still receive "Cannot connect to server" over 4G.
I have an identical S3 that connects fine over both. Any ideas?
Resetting the Exchange Services (clearing data) made it give me a different error when I try now:
" activation failed. unable to connect to network. Try again with network providers default APN."
I've tried resetting this to default and it all matches the working S3.
For the future:
It was a setting under "Data Usage" and then under "Email" at the very bottom that restricted Data to WIFI on the email app.

Hi all,
I have a Touch Pro 2 on T-Mobile in the UK.
After receiving I'd quickly gone through and set up all email accounts and was happily receiving and sending etc.
However one day it dawned on me, the emails would only receive if I was connected via wifi, if i was just using 3G it would say "error synchronising".
I checked the settings 100 times and couldn't work out the the issue, even T-Mobile themselves couldn't help.
Then one day I found what I'd gotten wrong:
Go to Emails
Accounts
highlight account - Menu Softkey
Click Account in list
Edit Account Setup
Next until you get to the E-Mail setup screen with "advanced server settings" as a link at the footer.
Click "Advanced Server Settings"
Change Network Connection from "Internet" to "T-Mobile Internet"
This may be the issue with other networks as well so if you experience the same issue take a look and make sure there's no "orange Internet" etc.
Hey presto your emails will now download via all internet means as well as Wi-Fi.
Who knows why for T-Mobile Internet is actually only wi-fi and not "the other" internet on our devices.
Hope that helps anyone else in the same situation as I was.
I have the same problem but then with my provider Hi.
After a hard reset the settings aren't loaded correctly. I've also been on the phone with the helpdesk, technical helpdesk and a lot of people who really didn't understand a whole lot about phones and they all couldn't figure it out. Touch Pro 2 settings weren't available yet.
Finally I just looked up the settings from the Touch Pro and entered those manually. This worked just fine.
But, if you set the connection to "T-Mobile Internet" instead of "The Internet", it will never use WiFi for that account.
I have a TP2 on T-Mobile and my e-mail accounts are configure to use "The Internet" and it works fine.
Even with Wi-Fi off?
Is your a branded t-mobile handset in the UK?
Hi LocoNinja
I'd be very interested to now how you've got your e-mail able to use either WiFi or the phone's GPRS/3G/HSDPA connection...
Since upgrading to WinMo6.5 (official HTC update) I've noticed that I can only connect to e-mail via WiFi if I use 'The Internet' as the connection, and only connect via GPRS/3G/HSDPA if I use 'T-Mobile Internet' as the connection...
It's bugging the h*ll out of me!
Cheers in advance
possibly a t-mobile issue, as with my vodafone branded tp2 it works fine.
For example: If wi fi is enabled, it uses that. If wi fi is disabled, it just opens a hsdpa / 3g connection and uses that.
Did the same thing on the original VF 6.1 rom and with the newer VF 6.5 rom. Also works perfectly on the custom rom i am using.
Hi dazkeirle, that's what mine used to do on WinMo 6.1... I wonder if something else I've installed has b*ggered it up
Will have a tinker and let you all know if I find anything...
**Sorted it - It was WMWiFiRouter that had messed the connection up - removed, settings changed in e-mail to 'The Internet' and everything's working fine now
Pesky WMWiFiRouter V1.50 - it messes up your display time-out time too
I've noticed lately, that when connected via WiFi, my Galaxy Nexus cannot retrieve my emails from my exchange account - I get the unable to connect to server message. If I switch over to the cell radio (4g or 3g), it connects fine.
Has anyone else had this problem?
Thanks,
Wad
No trouble here since switching from my D1 to my GNex. I use touchdown to access my exchange email though and I'm always on wifi. If you don't use TD it is highly recommended. Great app!

Have you had this problem on several wifi networks, or just one?

It is most prevalent on my home network (att dsl). That said, it also happens at work.
It is an intermittent problem - it will sync sometimes, just not most of the time.
And, I do not use Touchdown, just the stock exchange account.

im having the same intermittent problem on my galaxy nexus over wifi with exchange
I have no trouble at home or at work using WiFi to sync with the default Email app that comes with ICS.
I am on a GSM Nexus and not using Exchange, I do see wifi problem when screen is off, however.
Large download / Shoutcast streaming will be interrupted within a few seconds after the screen is turned off.
From what I gathered, it looks like wifi went into Power Saving Mode (PSM) which requires supported access point to maintain the connectivity.
I wish there was a way to disable PSM on Galaxy Nexus as it appears that none of my APs support this mode.
I have a strange problem with my Galaxy Nexus. When I connect to the internet using the mobile network, the connection is extremely slow. (And by slow I mean around 2-3 minutes to fully load the google mobile search page). I tried the "Speed Test" app to test the network speed, but it simply fails after a while mentioning "Network communication issues" (maybe it times out?).
The weird thing is that other devices can access the internet fine when connected to the internet through the Nexus by enabling its WiFi hotspot feature. So the other devices can use the Nexus's internet connection with acceptable speeds while the Nexus itself can't. Anybody got any ideas as to why this happens? One thing I could think of was that the DNS given to the Nexus by the mobile network being slow (whereas the other devices connected to it use the DNS in their WiFi settings). I tried to verify this by using the "DNS Changer" app, but it didn't solve the problem, although I'm not sure that it actually changed the DNS used by the Nexus.
Any help is greatly appreciated.
Bump for a solution for this man!

Problem solved!
Finally found the culprit! It wasn't DNS after all. My carrier's data settings include an IP and port for a proxy. When I configured the APN on the phone, I entered them simply because they were there. Turns out that keeping them empty solves the speed issues on the phone. So the bottleneck was the carrier's proxy server. I guess tethered clients don't use the proxy setting on the phone and therefore didn't experience the speed issue.
Inspiration fixed wifi hotspot not connecting to internet
I wanted to thank you because your solution helped me fix my problem. I couldn't connect my native wifi hotspot on my GSM Galaxy Nexus to my Nexus 7. The wifi indicator would come on to my N7 but it stayed gray (i.e. wasn't connected to the internet). Turns out that last month I set up an APN to connect to T-Mobile via IPv6. Well, apparently, this creates a problem with using the wifi hotspot. I switched back to regular T-Mo connection and...if works! My GNex/N7 combo is fully functional. Thanks again for the inspiration!

Plz help; only able to access the internet via Wi-Fi, can't access using at&t network
Has anyone else had this problem? I can only access the internet using Wi-Fi on my N7A. I can't access the internet using at&t's network even
when the signal strength is showing 5 bars. I've tried accessing the internet using Chrome, FoxFire, etc, I get the following error message:
"You are offline.
try:
- Turning off airplane mode (if it was on I wouldn't be getting Wi-Fi)
- Turning on mobile data or Wi-Fi
- Checking the signal in your area"
My phone is a "new" gen unlocked N730A bought from Best Buy, I had this problem with APH1 and now with the update 2APHE.
I'm running the phone stock (no pseudo-root)
I've done a couple factory resets then tried to access the internet via at&t's network - no joy
I'm really digging my N7 (my second one, sent the first one back due to the recall), but it has limited usefulness if I can only access the
internet when I have a Wi-Fi signal. Thanks in advance.
Edit: Oddly enough I have no problem making or receiving phone calls and I can send and receive text messages over the at&t network.
However I have no internet capability over at&t's network.

check your APN settings. Google it.

You are correct, the problem was an incorrectly set APN. I took the phone to a local AT&T store and
they were able to set the proper APN, now I get great 4G service. Thanks.
I have the S9+ on Verizon running Android version 8, Oreo. I don't want to upgrade because there are certain things that work on Oreo that don't work on subsequent versions.
Last week I started getting an exclamation mark by the wifi indicator with the message "Internet may not be available" however, the internet still works. I've tried different routers, forgetting the network and adding it back, assigning the phone a static IP address, rebooting, clearing cache, and resetting the network settings. Nothing has worked. I really don't want to do an FDR.
SOLVED: I had activated the URL filter of my Asus router. For some reason the phone thought internet was not available. I removed the filtering and the wifi is back to normal.
