Testing wifi speed today at my friend’s house. He was complaining about his internet. He is using the same router as me. Asus RT-AC88U. He was using Version 184.108.40.206.382.18991 firmware. Which ended up it seems that the advanced wifi page was weird. The menu went blacked out and it was unable to apply changes. Instead we changed to Version 220.127.116.11.382.15850. And we were able to look at the advanced wifi page to make changes. While we managed to fixed this. The speed was still less than optimal for the wifi. So instead I tried going close to the router which would provided the best speed and tested it out. Indeed going to near the router made the speed went up by many times.
