constant 'package loss' wirless connection wifi-card/router?

Hi,

Since the beggining i have had problem with my wireless connection, my laptop is an Acer Aspire 5745G Win7 and my router is an Asus RT-AC66U. Originally my laptop only supported the 2.4GHz band and i have allways thought it was interference from my neighbours because everyone was using the 2.4GHz band and the channel distribution is awful. So i bought a new wifi-card Intel Dual Band AC-7260 now im the only one with 5GHz but i still get constant package loss. The router is placed 3.5 meters from the laptop and its only a thin drywall and a bookchase in between so the signal is excellent.

I have run test with Pingplotter and it shows excellent when using a cabel either directly from the wall or the router. But if i use the wireless the results is crap. I have reinstalled the drivers for the wifi-card, the firmware on the router is the newest and i also tried a factoryreset. My router sends on both 5GHz(mobile and laptop) and 2.4Ghz(chromecast) i have tried using both the same and separate SSID. I have also tried forcing the router to only send AC with 'N/AC mixed' on 80MHz with no better results, i have also tried with 'only N' on 20/40 MHz same there.

With cable directly to the wall


With cable from router


With wireless at 5GHz


To exclude the router i have to make the same test on another device, does any one know a similiar program like pingplotter for Android Phones?

Can it be software issue with wifi-card? If i run Pingplotter in the background and click on the wireless signal down in the right corner of windows taskbar, the results in Pingplotter spikes for a second each time the list that shows all the wireless connections in the area appear in the right bottom corner. And if i hover over my connection it shows 802.11n even when the speed is at 866,7 Mbps when its cleary in AC.

  1. It is possible that there is a network in your vicinity using the same channel. I recommend using wifi analyser on android to see other networks and what channels they are using. Find an empty channel and set your router to it and see if the results are any better.
