I have a new 2020 iMac. I have a 400mbps WiFi speed account with Charter. Running a Speedtest the iMac shows over 400mbps. THEN an few minutes later the Speedtest shows only 100 or so mbps. I restart the iMac, the Speedtest shows over 400 mbps again. It happens all day.
At the very same time, my MacBook, iPad and iPhone are always showing speeds of 400+
Why does this happen to the iMac
Thanks

rkaufmann87,
I tested all day before answering. Your suggestion did the trick. With the exception of one random Speedtest that was in the 120mbps range. The entire day I had 400+ speeds in the Speedtest.
I ditched the Charter Spectrum DNS in favor of the Google one.
THANKS!! You know your stuff.
Do you use Charter’s DNS settings, if you don’t know or the answer is yes then change them.
Your welcome if you think this thread has been answered please mark it as such, it may help another.
