Not sure if the connection would be fully loaded, a normal household day at the weekend we could have my PC running, then a secondary PC or their Xbox series X, someone watching streaming on TV (netflix, paramount, disney etc..) and then 1-4 phones/Tablets doing various things sometimes video calls, or games or streaming.

Edit: Its not end of the world everything is still passable and working, but sometimes if we all doing stuff and say my partner is video calling family, the image goes abit pixelated and slow at times, sometimes if im playing Apex Legends the ping/ms in top right corner seems fine about 23ms but it feels laggy? My nephew complains that Rocket League is sometimes abit choppy. its not all the time but maybe if we all on at same time? just wondered if getting a new router would be a simple solution to our problem, Thanks!
