M$ Exchange on WiFi only

I hail from the Pre so I'm kind of new to Android so I'm still getting used to this thing.
I noticed though that I can't receive/send emails from my Exchange account while on Wifi only when on my work WiFi. I can browse the internet, receive/send from Gmail, use Google Talk, install from the Marketplace and so on. Just not send/receive from Exchange.
At work I get zero reception so I have no choice but to be on WiFi only, again this is my company WiFi oh and this worked fine on my Pre.
Thanks

Does anybody know? Do I have import a cert? anything would be helpful

does your work have a fire wall that is protecting information from coming in and/or out?

That definitely needs to be checked.
Also... What do you have for server settings? An IP address or a hostname? If it's an IP address, is it one that can be routed to over the Internet? If it's a hostname, is it one that is resolved by public DNS servers?
There's a million different ways your admins could have your company email system set up. You're going to have to go into more detail to get this resolved.

My job does have a firewall but I am able to use the WiFi for anything and everything except Exchange on the Hero. I even receive emails from Gmail with no issue.
My server settings are pretty simple, it is a hostname that can be routed over the internet, and yes it is resolved by public DNS servers.
As I mentioned before it works on my Pre and my iPhone currently. And again there is no reception in this dungeon so I'm stuck on WiFi only. If I go outside and get off the WiFi I get a slew of emails from EAS.

Does the Exchange work on every other Wi-Fi and 3G? It only doesnt work when your on your work Wi-Fi? Just trying to clarify.

OK, let's slow down and clarify....
Your exchange email works when you're not at work, but doesn't work when you are there?
Does it work from a laptop on wifi when you're at work?
Sounds like one possibility is the DHCP servers at work are giving the phone a bad DNS config....

Ok, in that case, my GUESS is this.
Your internal network is named the same as your external network name.
In other words, you named the internal network mycompany.com as opposed to mycompany.local. Because of that, the DNS on your server thinks its the authority for that domain. If you look for mail.mycompany.com, it stops at the server and doesnt go outside. But your pointer for mail.mycompany.com resides on the ISP's DNS server.
Thats just a guess, and that would cause that issue on the internal network only.
EDIT: Computers and such inside the network wouldnt suffer the issue because Outlook is using the simple network name like MYSERVER or SERVER as opposed to the FQDN.
Did you make your network?

Sounds perfectly plausible. Definitely the next thing to check.
Does Android let us specify the DNS server while still getting the rest of the IP config from DHCP? I seem to recall trying to set that and not being able to without specifying the full IP configuration (hate that...).

Why could he not connect off another laptop? using the conection off the laptop to go wirelessly to the wifi? I did this with an xbox 360 before. I dont see why i t wouldn't work with a phone

The actual device wasn't really the point of asking that. What I was getting at was whether or not the DHCP server on the work network was handing him a DNS server that would properly resolve the mail servers host name.....

The way to fix this is insert a pointer to the mail server FQDN in DNS on the server. Make an A record in DNS and point it to the IP.
I see this all the time with people that dont know how to make a server, they try www.mycompany.com and it wont work because they made the internal name the same as the external, if they dont host everything.
Anyway, I do believe this is a DNS issue, and it goes beyond the scope of the phone and this forum IMO.

If I access the mail server internally it something like server01 and externally it would be mail.mycompany.com <- this is what we've used in the past to set up EAS and it has always worked.

Agreed. It's really, really easy to set up a DNS server that works 99% correctly. Unfortunately, that means that lots of admins never spend the extra 10 minutes taking it from 99% to 100% correctly.
My apologies if my questions seemed odd, but I've learned through many long hard years in IT that it's better to ask end users questions they can answer, and then infer the info you need from that, than to just ask directly for the info and get a blank stare as a response....
Also, the reason for wondering if we could specify the DNS server was in an effort to find a solution *around* the misconfigured DNS, assuming he wouldn't have access to fix it properly... (Of course, that workaround would then depend on the company routers being configured correctly....)

Wait, Im confused...
Is MYDroidHax the IT guy? He said 2 phones worked there...and seems to know more than stated.
Is that what the issue was?
I seem to become confused with all the responses.
LOL.

[Q] Sites Accessible via Wifi, Not Cellular (Intermittent)

Hi All, I have a question I'm hoping someone might be able to help me with.
I have a Nexus S i9020A running CM 7.0.2 on AT&T. I've noticed something strange lately and can't quite pinpoint the problem.
I'm running a server at my house with a no-ip address to access my tv show downloads. I'm able to access this from the browser (any browser) while connected to wireless (in my network, or out) but only intermittently while on cellular data. When it isn't working it simply keeps trying to connect until it times out. I haven't yet recognized a pattern of when it works vs when it doesn't.
I thought for a bit it might be a DNS issue, but even with the straight IP address it won't load. Funny thing is, I'm still able to SSH into my router using ConnectBot, so I know the address is correct and the phone can see it. Other apps like RDP won't work either while I'm having this issue.
It's not the end of the world, but it sure is annoying. I'd like for it to work whenever I need it. Any ideas?! I'm stumped.
Thanks everybody!
Tim

I know nothing about networking, just so you know. It sounds like you know much more. I will offer a guess. With some other phones than the ns, sprint has multimedia proxies set for when you are on their network. Streaming music works on wifi but not cell. Use the msl to get into settings, ##data# is the code for sprint phones, and I forget what they are called but there's two proxy addresses and ports that need to be zeroed out then reboot in order to get streaming to work. This is probably not a solution for you but I thought I'd offer something since nobody else has chimed in yet for suggestions.
RS something or another. The other setting is always right next to the first one and generally at the bottom of the list of settings. It could be in advanced or multimedia. Different places for different phones. It would be wise to write down the default addresses and ports before changing them in case it doesn't work or breaks something. It usually doesn't though.

Hey herb, thanks for the response. I see what you're saying, but I don't think it applies here. I know I made it sound like I was streaming or downloading music through the phone...my mistake. What I actually meant was that I'm accessing a web site running from my house to control my home machine downloading music. It's nothing complicated, I'm just sure I'm explaining it terribly.
But, essentially it's just a regular old web page. It's just very strange that it would work wireless and not over cellular. They do run on funky ports, so that they're blocking or redirecting some stuff is very possible. Annoying...

Connecting your Xoom to a wireless network with a hidden ssid?

Hi Guys,
I have searched, but did not find a working solution on how to connect the Xoom to a wireless network, which does not broadcast its ssid. My friend has an Acer Iconia and he can connect to hidden networks, so Android 3.0 must be able to.
Has anybody been able to get this to work on their Xoom?
Cheers,
Deputy

You can type the name of the ssid in if you know it. And if you're in range, you'll connect.

Hi, yeah, that works on my phone (CM7) but not on the Xoom... It is disabled for an okish reason, but I was hoping someone would know how to enable it anyway.

The Android framework doesn't properly support hidden SSIDs, unfortunately.
There's a WifiManager setting for network entries, but it doesn't actually do anything.
IMO there's no good reason to use a hidden SSID. It really doesn't provide any additional security (A determined hacker can find your network anyway)
With the incompatibilities it causes with many devices, why do it?

Not sure where some people are having issues adding hidden SSIDs, I had no problem adding my network to the Xoom right out of the box a couple weeks ago. The wifi setup function under wireless settings actually prompts for your SSID when manually adding one. Perhaps I was lucky in getting a less-problematic Xoom, but it works just fine for me. The 3.1 update was pushed out to it automatically last Saturday and I still connect no problem.
Wifi is pretty quick, though it sucks to hear the info about it not utilizing the full potential of 802.11n.
Don't believe the hype that your system is not any more secure through SSID cloaking, doing so makes it is less of a target, unless it's the only AP around and someone knowledgeable enough is looking to get in. Don't use it as your only layer of security, but use it in conjunction with the strongest encryption your systems support.

I agree with both of you, there is no reason to use it, but my employer seems to have a different opinion, so I can't do much with it over there.
Thanks for your replies.

Have 3 Hidden-SSID networks configured in my Xoom; I bet your problem lies elsewhere (special chars, maybe? Misspelled SSID?)

I have tried it many times. I am sure the spelling is ok. Mine uses no authentication. Is it the same for your networks?
Would be very interesting to find the difference. (but, then again, I can't change the network properties at my company)

WPA2-PSK for all of mine.
(But you've gotta wonder- what's the effin' point of having a hidden SSID for "security" but Open Authentication?!)

I just bought a second Xoom for my wife and ran into this same problem with hers. Mine connects to the network fine whether its broadcasting or not, I normally have it turned off. Hers will only connect when said broadcast is turned on.
it makes me think it has to be a setting somewhere that's off on hers, just have to find it.

[Q] HTC Desire HD WiFi not connecting at house but does everywhere else

Hello. My phone connects when I go to other people's houses or at school, but not at my house. My router is set up with a WiFi access list so that you need to enter the MAC address before being allowed to even see the network. I have triple checked that the WiFi MAC address from my phone is entered correctly as I did everything else. Does anyone have some advice?
I appreciate everyone's time!

Make sure the channel is set to one which your device supports.

I downloaded an app called wifi analyzer; will that help me find which channel to set it to? How do I know which are supported.

Go to the wifi settings (on your device) and see what channel it is set to (usually under regulatory domain).

maybe you should set the maximum number of channels, otherwise some routers might be excluded.
controls which channel is your router and then try to configure the connection manually.

Sorry for the late reply; I have been pretty busy.
I tried a variety of different channels but none of them seem to work. I had seen that the phone does not work on Channel 13 but that did not seem to be the problem. I have also tried changing the security password type on my router but that did not work either. Are there any other suggestions? Thank you again.

your router is wireless network is to advanced for phone allow you network to be seen and just have to enter a password to work it will work been there
ps when it works hit thanks please

I'm assuming you did... but just in case, you did hit the "Wifi Protected Setup" on the phone right?
I swear i'm not trying to make you sound like an idiot, but we all have our "oh damn i forgot about that" moments, know what i mean? lol

Lol no problem. But yes I did do that

i'm also assuming then that you took ALL security off your network, leaving it open with no password, and that didnt work either.
past that, I don't know what to tell you. some routers are better than others.... maybe yours just hates you?

MS Tellme wont' work on wifi

Any special ports need to be open or are used by tellme?
At home it works fine when wifi is on. At work it says it cannot connect. it may need a port that is being used for something else on our network and i just wanted to verify

I have a similar issue. It doesn't work on cellular but works perfectly fine on wifi. Been troubleshooting with carrier and LG for a while and still no resolution.

Yeah I have the same problem and it is a port blocking issue because at work our Watchguard blocks tellme and downloads from the market but luckily I am in IT so I just added a firewall exception for my phone so it is ok.

Did it give you the actual port numbers? That is what i need to know. I am the it admin and tellme isn't on a block list on purpose. Downloads work fine.
Cell works fine also but i like to save battery and use our wifi when i'm at work.

Still no answers on this anyone know the ports?

Can try to find you can set the port the software to install. But the software I forgot.

That's the thing. I checked all the logs for the ip of my phone with the firewall. It shows no logs of blocking it, so i am thinking it uses a port that our exchange server, vpn, or rdp uses or some of the other devices and the info is getting forwarded to them and disguarded instead of my phone. THat is why i need to know what the port is.
