This December I purchased an HP laptop with windows 10 preinstalled. Its part of my network which includes 4 laptops and 2 printers and 1 very old workstation. With the exception of the new HP, all the other equipment is running on Windows 7. Some of it runs through ethertalk and some run on WIFI.
There are zero problems with WIFI and internet connections and downloads on the older units. They are all properly firewalled, including the new HP.
I find the HP with windows 10 less than impressive, as a matter of fact the words I would like to use don't belong in a forum. Use your imagination. WIFI performance in Windows 10 is wretched and incompetent. Fixes offered online don't work. The basic problem is that Microsoft is pushing a defective product out on the market. There are uncountable complaints online about the WIFI and image bluriness. Despite having a network that can push itself to one gig, the pace at which the WIFI runs on the new HP is well below that. Even my aging seven year old Toshiba satellite with its outdated 32-bit architecture runs faster in WIFI and has no issues with blurry images.
When the Windows 10 laptop is wired through ethertalk, the internet works fine. When it runs on Window 10 WIFI it is like a dial up modem. Images in Google Chrome when running on WIFI are fuzzy, and never appear to fully download. So, as a result, my brand new laptop for me at least, is a useless Lemon, a wheelchock, a bookstand, maybe soon an expensive frisbie. Trying to go on youtube is not possible, the laptop just spools endlessly.
Thanks Microsoft for continuing to be the Yugo of the operating system world (debugging-what? I can't hear you). You should have stuck to windows 7. We can discuss it, the real thing I want to see is a viable fix from microsoft and not endless instructions about "settings." Let's get this serious problem fixed NOW.
