New bios may be in preperation to avoid win7 problems or some know hardware limitation or problems. I usually update bios's. I don't know for sure but Dell 'should' have a simple failsafe install method for it. That realtech driver update is very popular. My 1.5 yr old toshiba - toshiba just offered a dozen or more hardware driver updates, mostly dealing in advance for Win7 updates. Which by the way the amazon's and other big software sellers are offering upgrade pre-orders till July 11th or while supply lasts ... 50% off sale... $50 home premium and $100 dollars pro versions.

Thanks Zep. Yes, I have noticed that Win10 has begun downloading weeks ago. I don't mind that as it will be less tedious later to download all at once. I just won't install it yet. Yes, I also had a concern as to whether I "need" to reserve my copy of 10. I see when I go to Control Panel - check to Win updates, it gives me a big old blue box saying Win10 is coming soon...reserve today. I suppose it will stay like that until I reserve.

Nice to see "Happy Campers".. was was hopeful as the load, long time as it was, seemed to load everything, all my history and some rather old drivers, e.g., Palm Desk Top. But over a short time, must be about the start of this thread date, the whole computer has bogged down, not just browser, both Firefox and IE, I'm not using the newer whatever-browser, but even the WiFi interface. I try to remember to shut down my WiFi when I am done, but leaving the computer on. Then I click on the wireless Icon and click connect. It is not a click, click, click operation, long (what 5+ seconds or longer) delay getting to each click. Wasn't that way in the beginning. I use a password as that is port of the IE security for saved passwords, I use a master pass word on Firefox.. suppose that's the problem? Wasn't in the beginning. Just before this exploration and gripping Firefox forgot all, I mean all, its personal data. I did a refresh on Firefox, then a restore on Windows 10, still total amnesia for Firefox. I have backup on a flash drive, but haven't plugged that in to recover. Seems houzz log on survived, must be something at the houzz end, not Firefox memory. On Linux, I used the Ubuntu GRUB to set up the dual boot, and right now I don't recall what the problem is... maybe it too slowed down, maybe there's something wrong with my mental clock too high an expectation. That possibility noted, I did some blogging on the Ubuntu forum, now a member, and there was some agreement on the problem. I have considered using XUbuntu to resurrect a XP Dell desktop that is very sick. But rather than dual boot, thinking using a USB Hard drive as the boot for XUbuntu and leave the Windows boot loader in tack. I think that leads to my too slow peeve. I suppose I may have problems with drivers too with Ubuntu.. I want to run my laser printers for one thing. The one dual boot I have worked "out of the box" with my WiFi.

I use to have a couple of very Cheap Bluetooth Dongles that I used and they worked great. They did after many years of service fall apart! I tried replacing them with more expensive dongles and couldn't get them to work. Snidely is right, kinda hit and miss. I do however think your problem my be deeper. Since the release of Windows 10 there have been lots of problems with WiFi Adapters and Bluetooth Adapters not functioning correctly or not at all. The 2 Acer Laptops I purchased a year ago had Windows 8 installed when I purchased them. I installed Windows 8.1 shortly after the purchase. The WiFi/Bluetooth Adapter worked great in Win 8 & 8.1. Once I installed Windows 10 on July 29th neither the WiFi or the Bluetooth worked. I ended up buying two New Cards for the Laptops and now the WiFi/Bluetooth are working great. My sister purchased the same laptop with the same WiFi/Bluetooth Card, after the Windows 10 upgrade her card works fine, no problems. The funny thing, the card that stopped working worked fine in a different Acer Laptop with Windows 10 already installed!
