A bit late i finally got an USB 3.0 Gigabit -Ethernet -Adapter(Linksys) for my 2 Ultrabooks.

1. Provider confirmed that nobody is sucking speed on my Wlan but its terribly slow til now. must be 1000Mbit/s Lan, 1/8 of that 125 with Wlan. But i get hardly 40.

Will deactivating Wlan speed internet up? have slower Celeron 4/64 and quicker i7/16/1TB Ultrabooks. Wlan also needed for smartphone.

2. have usb-hub. better attaching adapter NOT on this 4x hub right?
