Cannot connect to Facebook on WIFI, only 3G

Hello,

I have the same problem on my Lumia 920. Connected to Linksys E3000 Facebook wont run. I've connected a Wireless TP-Link router wired to the Linksys E3000. After that I am able to reach Facebook while connected to my wireless TP-Link router. It's weird that it wont work with the E3000. Don't know what issue it could be.
 
actually i have the same probleme i cant get acess to facebook n wifi when using wifi...am using an htc desire 616 can anyone help me?
:straight:
 
*Sorry for major bump-no other forums seem to have a thread of this*
I have this problem its rather annoying and i end up using all my 3g up...
This happens to me on Game Apps on my IPhone and laptop[pertically certain ones i.e clash of clans etc but java ones work](allowed via 3g but not wifi) yets on everyone elses phones/laptops etc it works fine but isnt working on mine ive reset router but didnt do anything unfortuanately any other suggestions??
Thanks inadvance
