The problem is about the images like profile images, post's images etc not loading, or loading a small number of them. Also you may have problem to load the games.
I take a look at my router's logs, and I see the below row
**SYN Flood to Host** 192.168.2.10, 42277->> 209.85.147.132
I check that the ip address 209.85.147.132 is a google ip. So, from this row I understand that my router detects a (wrong) Flood attack.
This happens because browser open a lot tcp connections to the same google server to load the separate parts of the page like images, scripts etc. The router detects these multiple connections as flood attack and block them , so the browser can't load the images.
The solution it's easy, the only thing you must do is to change a value at your configuration of your router.
Specifically you must change the value of the below setting
Maximum incomplete TCP/UDP sessions number from same host *
This may has default value 10, you try to change to 50 and save the settings. Now try to reload the google plus page, I hope to see the difference like me!
* The settings may different for different routers, you must search to find it. In most occasions this settings may be at the router's firewall settings ans specifically at Intrusion Detection.
