I experience ~10% packet loss when running wireless.
What it means to me is an average torrent download speed at 50% my wired speed (because of time out the speed goes to max, drops down, goes to max again etc..).
When playing online games, I get lag spikes once every 2 minutes lasting 20 seconds.
The setup I use:
Net gear r6300 router
Laptop running ubuntu 14.04 with intel ac7260 lan card
For testing, i have my laptop in the same room (2 meters from the router) and got the following result: 65 packets transmitted, 57 received, 12% packet loss, time 64077ms.
I tried 1000 packets from a windows machine with 10% loss. When using cable there is no problems.
Do anyone got some clue what could cause this?
Edit: Forgot some info and made some more testing
Running the router with DD-WRT does NOT solve the problem.
Running 100 packets through 2,5 ghz produce 0% packet loss.
