Very slow internet connection issues.
Very slow internet connection issues.
Your router model is a N450 TP-Link TL-WR1043N. It has been working well for three years until recently. During your summer vacation you returned from your parents' house and noticed the Wi-Fi is very slow. Your internet speeds are poor, especially with your One Plus 7 Pro. Your cousin uses an iPhone SE and has good performance, while another friend with a Samsung S10+ gets excellent speeds. You've tried changing channels, bands, and antennas, but nothing helped. What could be causing this issue?
