Serious Wi-Fi Glitch in High Sierra!!

[soamz]

Hello, I found a very weird bug on high sierra and its confirmed as its same behavior in all 3 of my MacBook and iMac.

When I connecting two USB-C hard drives or pen drives or SD Card, then WiFi stops working.

Internet stops working and if I disconnect and reconnect the SSID,it says it cannot connect.

If I disconnect the USB-C drives and reconnect, it immediately gets connected and internet starts working.

If I again connect the drives, then again internet stops working.

odd, try perhaps changing the wifi channel; nothing like that happening here (2 macs)...

If it happen on all 3 of your Mac, then obviously it's not the computer's hardware issue.

By considering there is almost no similar report from other users, I will safely assume it's not a widely spread software issue.

So, I will narrow it down to your own accessories's issue. Did you connect them via the same USB-C hub (or same model)? If yes, take this hub to Apple store and test it with their Mac.

yes, it could be the hub itself; i've seen reports of a usb-c hub that was interfering with wifi (an anker, i think... which i have, and is fine fwiw)...
