Wifi problem

  1. My problem is that when I try to connect to internet through Wifi it says Limited connection and troubleshooting says that Wifi IP configuration is invalid, but when I use cable the connection is fine. It all happened after I plugged ethernet cable from router to a new PC and if I connected it back to router few days later I got that problem with all devices like phones and laptops. My ISP told me to get a new router, but when I change under IPv4 properties from automatical to following:
    IP address:
    Subnet mask:
    Default gateway:
    Alternate DNS:

    with that I get like 1-2Mbit connection which is slow and I'm not sure that it's safe to use.
    I have also tried to restart router many times.
    Can anyone help me to solve this?

    Perfectly good AND safe.
    Your symptom sounds like the DHCP reply is not reaching the device. Set it back to AUTO, connect
    and then get the config again with ipconfig /all. If you see 169.x.x.x, that's a DHCP failure

    Yes, I see a IP address there but how to fix that?

    What OS? Frequently the firewall can be wrongly configured for DHCP.

    I'm using Windows 8.1 Update 1 64-bit.
    But I'm not sure that I should do these netsh commands when I already get from ipconfig/renew "No operation can be performed on Local Area Connection*2 while it has its media disconnected."
