Not using Kaspersky, now what?
backup tons of data! So the clean installation is the LAST RESORT, when upgrading the computer fails. And this is the job of us experts, to make sure it won't fail and save all this trouble.
PS: Microsoft Security Essentials is an antivirus too and you should definitely uninstall it if you have that, since it is not compatible with Windows 10. Windows 10's Windows Defender is the equivalent of earlier Windows Security Essentials so there is no version of Microsoft Security Essentials compatible with Windows 10.
Rarely does a user having issues on an upgraded OS solve their issue in a day, and it would only take a day at most to reinstall all applications, even on a system with a large amount of applications. Without using my LT install, it takes me ~ 6 - 8 hours to reinstall all applications and another day or so to get the customizations set, custom scripts put in their proper directories, tasks imported into task scheduler, etc. All one has to do is peruse the threads about issues with Windows 10 to determine it takes well over a day, usually several, for them to troubleshoot issues caused by the leftover system critical driver files copied over to the new install during an upgrade, of which are never compatible with the upgraded OS (the exception being Windows 8 -> Windows 8.1).
Each is welcome to do what they wish with their PC, but it can be surely said that running an upgraded OS will result in issues and hours, if not days, troubleshooting those issues... that is something most would rather forego, especially when more issues will pop up down the line. It's never a matter of if problems will occur on an upgraded OS due to the upgrade, but when they will occur.
Hello from me also.
Here's my story... I have a Lenovo Y50-70 laptop with free bios. I've installed windows 10 pro and dowloaded all drivers and updates from official sites. Network error occured as most of you guys. I've wondered many sites and didn't find any working solution. I've tried most i read here but also nothing happened.
In my despair i've reinstalled windows following all istructions for a clean install. This took me 2 days cause i had lot's of parameters to configure with some of my programms. I've even changed router with a lot of cost for me ( Tp link archer D5 ) , but that didn't solve anything in the end. I was using my laptop normally till one day ( i think about 15 days after clean installation ) that the d@mn message poped up "some network protocols are missing from this computer "... Disaster!
All updates are installed from microsoft and Lenovo's page. Bios is updated properly ( by me ) also from the official page. I've even updated drivers from device managment ( auto search internet for updated drivers ).
When that message pop's up, i right click on the wifi icon in notification bar and execute " problem confontation "
The wifi then come's back but it says that i have an ethernet cable problem ( i don't have an ethernet cable connected ).
My wireless card is " broadcom 802.11c".
Any idea what might be the problem?
If there's a legitimate issue, it's possible the issue is the broadcom drivers, as Broadcom/Dell Wireless drivers have caused continued problems with Windows 10. It took both almost 6 months to release a fix for their original wifi card drivers released in June/July, of which caused constant BSODs and other issues. I'd be curious to know if you disabled the wifi card and uninstalled the drivers if the problem would cease.
It was also mentioned by another member that OpenVPN, or other software that installs virtual TAP adapters, could possibly be the culprit... if you have any SSL VPN programs or programs utilizing virtual TAP adapters, I'd try uninstalling them and see if the issue persists (again, if there's a legitimate issue other than receiving the error).
Also, if you bought a new router simply because of this, and you'd like to return it, please do so, as this has nothing to do with any router.
The problem emerges one or two ( maybe more sometime ) times in a 12 hour use . It usually happens when i leave my computer. I'm not shuting it down cause i use torrent to download-upload. When i come back i see no internet connection. I have an android phone which is always conected to internet. So i beleive that it's a problem of my wireless card. As i've said before, i've tried most of the things i've read here,but still the problem remains. The new driver is indeed released in July and that's what i'm using. I know that it's not my router's problem , but it was really old ( 7 years + ) and needed a replacement. I would have bought it some time in the near future anyway.
Should i uninstall and reinstall it? Should i do this via interner or should i install the downloaded driver?
( As for the programms , i don't think that they're causing the problem. I have : nod32, teamviewer, Vuze, ccleaner, winrar, acrobat reader, adobe air, ms office 2016, skype, cpuid, canon utilities, deamon tools lite, hard disk sentinel, logitech set point, youtube downloader, youruninstaller and virtual dj 8.)
You'll need to verify what type of WiFi card type your motherboard has, as there will be a group of letters in the 7260 model number that designates what format of card it is (it was released in 3 or 4 different formats). You also need to ensure you buy from a reputable seller, as Intel's cards are counterfeited in Asia. Once you receive the card, and prior to installing,, google how to verify if the card is counterfeit and check the card against the pictures that will show up on Google to differentiate counterfeit from legit cards. Intel is one of the best in the industry for releasing regular driver updates (at least 1x month or so), and because of their quality, both in hardware and support, I'm partial to them above others
