Seems this has started about a month ago.
The internet either starts out fast then shortly after drops to half speed or less, or starts slow. Disabling/enabling the network adapter (from Control Panel) restores the speed. This is happening on both a laptop running Win 11 23H2 and another running Win 11 24H2. The MIMO Power Safe Mode setting found in the Advanced Properties of the Network adapter do not seem to have an effect. The default is Auto but even setting it to No does not help.
There are the results from running speedtest.net are:
Auto SMPS (default 707 172
No SMPS 627 149
Static SMPS 729 173
Dynamic SMPS 600 175
The speed on my iPhone seems to be consistent
iPhone 473 174
While running one of the speedtest the download speed was up in the 600's and at the half way point dropped to the mid 22's.
My router is one of those locked-down ISP models so I cannot change any settings.
This seems like a Windows issue but it could be the router. Yes, I have rebooted everything.
Any suggestions?
