Gcm problem - Greenify

When i greenify gcm related apps such as messenger and fb and my phone didnt connect to internet, the gcm seems not functioning. I mean when i already connect to internet such as wifi or mobile data, that apps still didnt wake up to give me notification. This seems to be okay when the notification arrive while my phone having internet connection. Hopefully someone can understanf my problem. And @oasisfeng can u confirm this problem ?

GMail sync only with home wi-fi

Hi
I'm not sure if it's Android or Transformer prime thing.
My google data (gmail, gcal) syncs properly and immediate when i'm @home with my wifi network, but refuses to automatically sync at the office wi-fi network.
The office network is freely available to the device, i can browse the net without any problems.
Can figure it out why the sync doesn't work.
I have noticed the same issue on mine except my home network sometimes has the issue too. I have resolve it by disabling the sync and then enabling it again. This method works for a little while then it seems to go into the no new notification mode. I have to manually refresh in gmail to get my new mail to show up. It is annoying. I even send test emails to both my phone and tablet, but it will not ccome through until it feels like it or unless I manually update. My xoom does not do that.
I have a sort of similar thing. All I know is that I'll be delivering pizzas while tethered. As soon as I get home, and turn off the tethering, my tablet connects to the home WiFi and gets one or more notification noises as it if wasn't syncing the same way when tethered. The oddity is that it doesn't know I'm on a mobile connection so it isn't trying to save bandwidth. I suspect there is something in the security or ports that makes it's connections to the home network different than when tethering, or when you are at work.
I can't speak to the issue regarding tethering, but for those of you having issues at the office, this is most likely due to firewall rules. I work for a cybersecurity software company, and have been fighting for them to address this as both my phone and prime suffer from the same thing.
If you have a good relationship with your IT/Corporate security people, try bringing it up with them.

[Q] ICS Proxy

The proxy works fine for using with the browser, facebook twitter etc but i dont seem to get any notifications whilst it is in use ie: connected to wifi all day at work but i get no email, fb, whatsapp msgs, as soon as i turn off wifi and am back on data connection everything comes through at once. I can use al these apps fine though through the wifi. E-mails occasionally come through on there own accord, but more often than not they dont.
Anyone else have this/got a fix?

Can't connect to anything google unless on Wifi

My Google Assistant, my Google Voice search and Chrome will only respond if I'm on Wifi. I'm on mobile network, with full bars and it just doesn't work. It keeps saying something went wrong or no connectivity but I can still use Facebook and other apps with no problems, it just seems to Google is the problem. As soon as I turn on the Wi-Fi everything seems to work perfectly but as soon as I turn it off Google stops working. Any help would be appreciated.

Question WhatsApp issues with Wi-Fi Connection

I have tried different Wi-Fi connections but it sill once in a while tells me that specific app can't work on Wi-Fi, only with mobile data. The issue with that is that I don't have good signal reception at home. Would appreciate any suggestions to solve the issue. I have tried several solutions found online such as: uninstalling and installing back again with a backup, deleting cache and data, resetting Network settings. I have never had an issue like this before with anyother phone.
You can keep the Wi-fi connection at the center of the house which will cover eventually every place, or keep it closer to your room so it won't get disconnected! As for the apps, you can go to the app settings and change the network usage from mobile data to wi-fi. Which apps are not connecting to Wi-fi?

It only happens with the WhatsApp app. I think I found a workaround. This problem may happen if you have multiple access points in your house. Even though is not a proper solution (the issue never happened with my old phone), you just have to turn off and on Wi-Fi and dismiss the notification. WhatsApp will probably work fine after that.
