So in my PC, I have the TP-Link N900 dual-band PCI-express adapter. Now I have Frontier, and we have 500/500 connection. (we recently upgraded) This particular adapter only supports up to 450mbps, so I think it's a little outdated. My main issue isn't with the speed however, as the 100+ I get on WiFi right now is usually enough for what I want to do. My issue is, my connection to online games and when streaming stuff is horrendous. My ping to my router, even though its only one room over, is always 10+, and I get stuttering and sometimes drop connection altogether in an online game. It's unplayable. So I've been using a Powerline Network (which yields good connection, but only yields about 6Mps Down and 12Mps up, yikes) I want to know if anyone thinks it would be worth upgrading the card? Like I said I think mine is outdated, and while it is dual band, I still found that my smartphone (iPhone 8) gets a waaaay better speed (ive gotten 350download on my iPhone right in front of my PC that can barely break 110) So I believe the card is definitely a factor here, it's just a matter of whether or not I upgrade. I have fiddled with the antennas on my card a little, and it seems to make very little to no difference. If anyone for some reason knows the optimal antenna positions, or has a suggestion for a great PCI express card, OR if you even have a good solution for a powerline network that can get decent up/download speeds, that would be great. (Also, my powerline adapters are the generic white TP-Link ones. Thanks in advance for any help.
