Xperia J problems with Facebook and wireless

[Schmoozal]

Hello out there. I hope this may help towards getting some kind of resolution to the problems I'm having with my Xperia J.  I've had problems with my facebook cutting out all the time????  Also, we have a new router and since it's been installed I cannot connect to wifi by using the home connection.  I try to connect, it says that the signal is either excellent or good then when I click to connect the signal drops to poor and it keeps trying to authenticate and doesn't connect at all.  The wireless connection with other devices in the house are fine.  Also when I go to work, the connection there is fine too.  Can anyone help?

When it comes to your Facebook I suggest that you update to the latest update for the Facebook application. 

You can also clear data for the Facebook app under settings > apps > Facebook > clear data. Restart phone and try again. 

When it comes to your WiFi it sounds like you have put in wrong password for the network. Try to press and hold on the network in the Wi-Fi menu > tap forget network. 

Then try to reconnect again. Make sure that you put in the correct password. 

If that doesn't help I suggest that you take a look at the following topic for more advices:

Thank you so much!  I did put the wrong password in - numbty! Silly me, it's working properly now. 

You may be able to help with another really annoying problem the predictive text on my phone is an absolute nightmare!! When I type any simple word and then add an apostrophe or an s it seems to think I need an entirely different word waaaaahhhhhhh! Also when I type "no" or "an" which are both very commonly used the predictor just goes to a stupid nonsensical word - any ideas??
