Where is the basis in logic of that broad statement ? ? Are ISP's all of a sudden stop servicing older PC's ? ?...are modems all of a sudden gonna stop functioning cause you are running XP ?
Believe it or not, I've seen this happen with sufficiently outdated systems. It's not the modem or any local hardware, it's the ISP. But, it's not deliberate, I don't think (though some are definitely worse than others, as they won't assist you adjusting your TCP/IP settings). As the internet protocols are updated, there becomes a point eventually, that transfers just don't work anymore. My Amiga system experienced this, where I could get a TCP/IP connection, but HTTP simply would not continue-- would
constantly stall out, when that never used to happen. I noticed that if I was using telnet simultaneously, it would somehow keep the web transfers going, and if I stopped telnet they'd stall out completely again. All/most other internet protocols worked still, just not HTTP.
This is why I didn't say anything about Geek-9pm's claim. However, there should always be a current Linux OS for old PCs... except maybe truly ancient ones.
Many users want to get Internet via wireless. In some places only wireless is the only choice. Windows XP had a serious flaw for wireless security. It was fixed with an update. Now in the future, there may be a new security standard taht most ISPs will use on wireless.
What "wireless" exactly are you referring to that ISPs support? Is it via direct ISP <--> customer microwave link, via satellite, or just Wi-Fi you are talking about? BTW, the Wi-Fi carrier signal is not actually coming from the provider, it's coming from your router.
