Hi all,
I've been having this issue on certain wireless networks where the wireless just stops working but stays connected and the only indication anything is wrong is when you go to load a page.
All I have to go in is the dmesg:
[ 3904.597032] ------------[ cut here ]------------

Everything I have found on the issue seems to be older and people solve it by updating firmware, I have check my firmware and I have the newest ones that others have said solved their issue:
[andrew@Andrew-Ultrapro ~]$ ls -al /lib/firmware/ | grep 7260
-rw-r--r-- 1 root root 683236 Aug 28 12:08 iwlwifi-7260-7.ucode
-rw-r--r-- 1 root root 679780 Aug 28 12:08 iwlwifi-7260-8.ucode
-rw-r--r-- 1 root root 679380 Aug 28 12:08 iwlwifi-7260-9.ucode
Any help at all resolving this would be greatly appreciated.
