Just bought thte E5-551 - not impressed.
Trying to conect to 5G - the wifi can onlty connect to 2.4. So pluged in broadcom usb wifi adaptor 802.11ac and still the laptop cannot detect 5G.
The adaptor picked up 5G with my old Acer Aspire but not on the new one. I tired diferent settings and it has the latest driver but will not detect.
Any idea's.
