Each time you connect an HDMI or external screw, the ping on the wireless connections increases dramatically. I have DELL Vostro 5470, Ubuntu 16.04 (but in principle on debian 9), Intel Wireless-N 7260. Everything is fine on the wire.

  • Perhaps food? - Qwertiy
  • Or maybe just a tip. It would be nice to check the connection speed from another device at the same time. - KoVadim
  • The Internet is nothing to do with 100%. As soon as I take out the cable, everything is normalized. And what about nutrition? In terms of the power supply is less voltage? Power saving is disabled, I connect with charging, I tried 2 hdmi cables, but I'm not sure about their quality - Anton Kapustin
  • if the power supply provides “in the butt”, then the additional load either triggers the protection (with subsequent shutdown), or simply the voltage drops. And some "blocks" (for example, a Wi-Fi module) may work unstably when the power is lowered. And some just have their own stabilizer. - KoVadim
  • Well, in the same battery costs. It's bad that I did not try it on Windows, as I bought a beech, I immediately installed Linux. And on the part of os what problems can be? - Anton Kapustin
