Hi Guys, I have weird issue with my laptop(Asus Vivobook S) wifi. • I use Airtel xstream box with good network speed with 100 Mbps. While in call there is drop in the audio and sometime lag in the video too. If I switch to the mobile hotspot it works fine but the bandwidth is not sufficient. This happens only on my laptop I check with other device it works fine. • I use primary Ubuntu 20.04 OS and tried configs changes(change WiFi power saving mode and upgrade drivers) the issue is still there. I have windows 10 with dual boot it also have the same issue. After trying all methods I'm still confused my laptop wifi is stable with mobile hotspot and not broadband. What are other things should I check to make wifi more stable?

Might be network interference. Try changing the wireless channel in your router’s config

Also if you have ethernet port and cable, check speeds using those as well.

1. I checked router config from my ISP provider multiple times could not find any issue as it works fine with other devices. 2. Laptop does not have Ethernet port.

@clever-vr-95479 • What does fast.com report when connected via wifi when the problem occurs? • Check with wifi analyzer app on your phone which band has least interference in your area and configure wifi AP to use that (only use 1, 6, 11 for 2.4GHz) • If all devices in your house support 5GHz, switch to it exclusively to reduce interference
