Assuming that when they made your laptop with 8.1 and they tested the wireless card to see if it worked before they mass produced it, and it did work, then yes it is a per person issue.
Windows doesn't handle the wireless connectivity. It is done by a wireless adapter hardware and software.
If you have an issue and you truly want to get the issue solved ask a question so you can troubleshoot it.
Laptops newer then 1 year are supported by the manufacture. They are also required to provide support for Windows during that year as part of their license with Microsoft. If they tell you its an issue with Windows that means they can't figure it out so they are just passing blame.
I have solved 1000's of connectivity issues and have not found a single one to be caused by Windows.
I noticed you have not started a single question asking for help with your connection issue. On top is a participate button. Click it and ask a question. By the days end, if you actively reply to the person helping you can have your issue resolved.
If people continue to sit around waiting for Microsoft to fix an issue that they have no control over you will never get it fixed. It is your computer do what you want, but I would rather fix the issue then waiting around for someone to fix an issue that they aren't able to.
There is absolutely NOTHING wrong with my Wireless Card and regardless of how many times you repeat this is NOT a Microsoft error, that still will not make it true. The FACT is, Microsoft's Windows 8 & 8.1 Operating System is 100 percent at fault for this and THIS isn't the ONLY thread on the Internet discussing this very same Wifi connectivity issue with no permanent Solution and it just so happens to concern ONLY Windows 8 and 8.1 Computers... (with most of them being recently purchased)...Now, due to 'some' of the Tips & Tweaks on this thread I'm able to maintain Wireless connectivity for several hours ..... A week ago? Generally less than ten minutes. I'm still experiencing 'Limited Connectivity' more than I like, but far less than I was.... due to some 'brilliant' minds on this Thread. I'm going to put you to the test and give you the 'opportunity' to "solve" my Wireless Wifi Connectivity issues ... Oh! and THIS Computer is on the SAME Bright house Cable Modem as two other Computers that have NO connectivity issues EVER and connect at 150 Mbps while this one connects at 72.2 Mbps.... This is a Toshiba S55-A5139 Laptop with 8GB (64-bit) system. Wireless Network Adapter is Qualcomm Atheros AR956x Wireless Network Adapter running Version 10.0.0.263. I've uninstalled, re installed, rolled back, updated and everything else you can think of with these Drivers. I've used Window's Drivers, (didn't help) and the Manufacturer's (Atheros) Drivers... (didn't help)... Installed Toshiba's Wireless Adapter's Drivers, (didn't help)..... The Rollback to a previous Driver Version so far has resulted in 'noted' improvement to connectivity.... I have done EVERYTHING attempting to maintain full connectivity on this Computer, including doing a complete System Recovery... to no avail. I have READ 63 pages of 'fixes' on this Thread (not counting all of the other 'fixes' on other threads) and applied ALL of them that applies to MY system, with no permanent fix. I assure you... I've been ACTIVELY working on this Computer for MONTHS attempting to 'fix' this Issue... that's hardly waiting around for Microsoft to do something about it... so far NO ONE has done anything about it.. except me. I've worked on Computers since 1985... and I've NEVER had to deal with anything like this... AND THIS IS a Windows SOFTWARE configuration issue. Now, IF you can tell me to do 'something' OTHER than what I've already done to 'fix' my Wireless Connectivity issues (and that's EVERYTHING within the 63 pages of this Thread, so if you 'repeat' anything that's previously been recommended, I won't do it because it won't work) then you will undoubtedly be Microsoft's newest Marvel and the HERO of this Thread. (As well as MY new Hero)... so, FIX my Problem as well as thousands of others. Astound us. Please.
