7# Firewall and Antivirus

 photo firewall-icon-370x250_zpsgdmyaxej.pngCheck your operating systems firewall settings and make sure it won’t blocks your chrome browser network connection. You can also try to disable your OS firewall temporarily and check does it solve your problem.

Just like firewall, it’s possible your computer’s antivirus program also creating some problem because of its security reasons and you can confirm it easily by disabling it for a while.

If you’ve having a comodo antivirus installed in your computer then you can add the file name to the trusted files which you can also be seeing in the antivirus’s sandbox.

 8# Internet Connectivity Issue

 photo Network-Internet-Connection-icon-min_zps0ncjkx69.pngInternet connectivity is more important than everything and without that your computer can’t able to do any anything. I suggest you to check your Internet settings and make sure no proxy are selected and if it does then remove it.

Now I want you to do is to restart your modem or router and check does it solves your problem or not, most of the times it does.

If you’re using a telephone broadband then it’s possible this problem is coming from the static noise in your connection and you can also check it by listening to the telephone’s dialer tone. If there is some static noise in the voice then I’ll suggest you to tighten every wire connected to each other in your connection and if the problem still stays then you can call to your ISP to get assistance.
