Good day. Newbie here trying to figure out the slow down on my TP Link TL-WN781ND pci-ewireless adapter using latest Tumbleweed. Tried some commands in the terminal via web with the following results:

See, I manage a higher bandwidth using Windows 10 (in Dual Boot Config | Legacy Setup in Bios), atleast 20Mbps connection (out of 35Mbps in 2.4GHz band) for the same wireless network adapter on the same PC. Distance from AP to PC is about 12 Meters w/ few partitions on the same floor.

Is this a problem within the driver? Link Quality & Signal Level are way too low [Link Quality=48/70 Signal level=-62 dBm]. I'm using a version 3 for Windows driver and here in Tumbleweed uses Version 1 [29:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter (rev 01)]. My ZTE Router | AP has no problems with reliable ISP to date, btw.

I hope someone could lead me to a right troubleshooting tips. TIA
