A clue! (Perhaps) After a day of using all my OCD and frequently checking Amazing utility speeds, all in range listed in first post, my laptop slowed considerably. At that time speeds from this laptop were 16 to 19 seconds. I tried from a second laptop, speeds 10 to 14. At this time desktops still fast, 0.8 or so. After several minutes, speeds came down to 5 sec or less on laptops.

So at that time hardwired network was normally fast, wireless very slow. Any ideas?

Looks like I'll be lookings for switch, network cards, wireless router, and laptop network cards. Any suggestions for the latter 3?

Thanks again. Gene
