[Basic Issue] = Connection Dropouts (need to troubleshoot or restart adapter), Random signal strength
[Standard Used] = 802.11n
[PC/Laptop Vender] = HP Spectre 14 3100eo
[Router Vender/Model] = Linksys WRT120N v1 (with Tomato firmware. Also tried DD-WRT, but same problem)
[ISP Provider] = Broadnet (Norway)
No drivers fix the issue, but changing some router settings made me get a much more stable connection with less dropouts.
