I just bought cAP ac for my home wifi. I decided to pair it with my hEX S and build my home network using CAPSMan. But I have some problems with my setup. My laptop never connects to the cap with full 802.11ac speeds supported by it, which is 866.7 mbps. I wonder why my laptop always use 20mhz channel width instead of 80 or even 40. Meanwhile, my samsung smart tv always connects at 40 mhz all the time, even though the signal is lower as you see in the picture. My phone also rarely connects at 80mhz, which my phone supports. How can I increase the negotiated speed so my devices can take full advantage of 802.11ac ? I have NAS on my home but I only get around 12 MBps because of this.
At some point I caught my phone connect with 80 mhz width. But this rarely happen. Most of the time it only use 20 mhz channel width.
Here is what chipset my devices at home use:
1. My laptop is Dell G7 with Intel Wireless-AC 9560. It supports dual-chain 802.11ac up to 160 MHz channel width (max speed 1.7 gbps)
2. My phone is Xiaomi Redmi Note 5 with Snapdragon 636 SOC. It supports single-chain 802.11ac up to 80 MHz channel width (max speed 433 mbps)
3. My Samsung Smart TV. I don't know the wifi chip used, but I believe it only supports dual chain 5GHz 802.11n up to 40 MHz width.
Also, here is my capsman config:
Code: Select all
