A 4GB Windows PC is now considered a little low on RAM. It may also be single channel. That's 2 marks against best performance.
I recently purchased a Lenovo Yoga 510 laptop running an intel Core i5 with 4GB RAM and Windows 10. Ever since I first started it up, I've noticed that the WiFi internet connection is considerably slower on this thing than on all my other devices. I ran a speedtest and the download speed is around 200 Kbps while my HP laptop gets around 550. It is noticeable but not too distracting when I'm browsing websites (most of them are static with just text and a few small images, student websites and papers and things). But it's particularly annoying when I'm watching YouTube videos.
On my HP, my iPad, iPhone, LG G4, Samsung S4 and the Toshiba laptop I had before, I could comfortably stream a video continuously on 480p. For the Lenovo, I have to pause and wait for it to buffer even on 360p. I can only continuously stream a video without waiting at all on 144p.
People have asked this on the Lenovo forums but the answers by the moderators there and other users aren't often very clear. I did go to the Power Savings settings and make sure the Advanced Network Settings - Wireless Adapter was on Full Performance. It already was so that clearly wasn't the issue.
The other alternatives seem a lot scarier to a complete novice when it comes to Hardware and anything beyond general use like me. If you guys could give me clear instructions on what I'm supposed to do to fix this, I'd be so grateful.
I can tell you any other information you need to know and run any further tests you need me to, provided you tell me how to, of course.
Thanks so much in advance!
