PS4 firmware 4.5 wifi problem fixed

And finally the much anticipated 4.5 firmware of PlayStation 4/4 Pro has arrived, with some very neat features: extended storage, custom themes. It’s a big improvement for PS4 users, well, almost: the firmware comes with a big problem for ones who are using wifi: the download speed is now terrible, and even worse, the lag in game is making the games unplayable. Before 4.5, I had no problem joining matches on Uncharted 4, and playing Titanfall was very smooth – ping is never more than 100ms. After 4.5, I can’t hardly join a match on Uncharted 4 (errors in connections), and the lag in Titanfall spikes to more than 2000ms, making the game totally unplayable. Test Internet Connection shows that I have a a few hundred Kbps upload and download, when the wifi connection is supposed to be 130Mbps (PS4 ony has 2.4Ghz wifi 802.11 b/g/n, only PS4 Pro has 5Ghz wifi), and my internet connection is 250/100Mbps, so that must be a big problem somewhere.
