I have 2 lenovo laptops connected to same WIFI router on same 5Ghz SSID and only 1 laptop will connect to 802.11n frequency.
- older Yoga 910-131KB (using Qualcomm QCA61x4A adapter) connects to Netgear R6400 v1 router on 5Ghz on 802.11n
-speedtest from 6-8 feet away 30ms ping, 127Mbps dowload, 37Mbps upload
New x1 Carbon gen 6 (using Intel Dual Band AC8265 adapter) connects to same router but will onlu connect on 802.11a
- speedtest from 6-8 feet away 12ms ping, 28Mbps dowload, 22Mbps upload
have unsinstalled proset wireless, router firmware updated, all adapter drivers updated and checked everything else i could think of.
anyone have any suggestions?
