Hi, guys... I'm on mtn fixed LTE. I'm currently using this router Tp-link (4G+ Cat6 AC1200 Wireless Dual Band Gigabit Router) . The download speed is less than 2mbps and upload speed less than 500 kbps and is not improving, latency about 78. What outdoor antenna will becompatible with this router to improve my connection?.. I need to buy one. thanks
