I'm running Fedora 22, 4.1.4-200.fc22.x86_64 and I'm not able to access the network through the wireless. This issue started recently and it happens at random times with random wireless networks.
Pinging IP addresses from the network (the router) or the internet results in about 95-99% failure rate.

I manage to connect to the WiFi but I have no internet connection. Or it connects with a ? over the icon.
I know the problem is not with the network because all other devices work fine.

I also tried different kernel versions and same behavior persists.

Any idea where I should start from?

Edit 1

It is a Toshiba Satellite E45t-A4100 laptop about one year old.

Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev 6b)
Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:c170]
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi

This is the message output by dmesg:

    How old is the laptop (?) you're using? Does this happen if you plug in a new(ish) USB writeless card? I'm told that the low-noise amplifiers on wireless cards can degrade with time. – Bruce Ediger Aug 18 '15 at 22:16

    what chipset is wireless? what do the logs say? have you tried try reinstalling the drivers...or replace hard drive and install another distro to if it happens. – gwillie Aug 19 '15 at 0:55
  • What are the outputs of iwconfig (to verify connection), ifconfig (to verify ip address), and either sudo ip route or sudo route (to verify correct routing)? It could be a simple routing- or dhcp-type problem instead of a hardware or driver problem. – rexroni Aug 22 '15 at 17:57
