So I recently got a PlayStation 4 (The Last of Us bundle) and I'm having connection issues. The main current issue is that it won't connect to PSN even though it's allegedly connected to the internet wirelessly. I try to sign into PSN and I get this after some time PSN is apparently up and running and my PS3 connects easily. From what I'm reading online, the PS4 has a weak wifi receiver? The PS4 is set up in the living room and our router is in my roommate's room (its his house) down the hall. Maybe...15-25 feet away. Everything else connects easily (My two tablets in my bedroom and living room; Wii in bedroom; Wii U and PS3 in living room; laptop anywhere inside or on the porch [even in my car, I get some signal]; roommate's laptop, PS3, and desktop in his room; our 4 cell phones altogether; and printer in the extra bedroom; haven't tried my girlfriend's 3DS, my 3DS, or other roommate's 3DS, but last I checked, those worked). We do have connection issues rarely, but it's never that bad (and he plays his MMO ALL DAY and NIGHT). Not just that, but the PS4's connection tests are successful (like I said, it's just PSN), but I can't even test that manually since it looks like I need to sign into PSN to access any kind of network feature. I'm hearing that I should use a wired connection for the PS4, but it's his router and it's in his room so I'm not trying to inconvenience him by moving it (Pretty sure his desktop is hooked up to it anyway). So tomorrow, we're thinking about trying to hook up my old router to the same network as well and seeing if it'll help. Not just for the PS4, but that will be pretty nice for all of us anyway. Looks like there's a few key things to make sure we get right, but it should simply boost signal strength by creating two of the same networks, in layman's terms. However, I'm trying to save that as a last resort and seeing if there are any other ways of getting the PS4 to connect to PSN. Here's a log of what all I've done since I got it Spoiler -Brand new out the box. Set it up and connected it to our network. -It needed to update to 2.57 (I think it was on 2.04?) --The update wouldn't download. (Red flag one about wifi issues. It seems like it couldn't maintain a stable connection long enough). --Reset to factory settings and tried again. Still timed out and failed to download. --Downloaded the update on a flashdrive and installed it from there the next day. -Connected it to wireless network again. -Tried PSN for the first time, got the above error several times. -Looked online and tried the following solutions: Setting DNS to 184.108.40.206/220.127.116.11. and 18.104.22.168/22.214.171.124 and changed MTU from Automatic (1500) to Manual (1473) and every combination of those and the default settings. Unchecking all boxes under Settings > System > Automatic Downloads and Uploads and rechecking them (can't recheck Saved Data because that requires me being signed into PSN). Every combination of "log out and back in, restart, reset router, etc. -Almost every connection test under almost every combination of those solutions is completely successful, but signing into PSN gives me the "time limit" error. Since I don't want to run a wire from his room, down the hallway into the living room, it looks like setting up the double router config is the best bet, but like I said: last resort (that and I won't be able to mess with that until tomorrow night and I'm looking to figure it out ASAP before messing with our network anymore). I'm going to try one of the games now for the first time and hope that works; maybe I'll be able to check connectivity that way (doubt it since I bet I'll need to sign into PSN for that!). Glad we got two physical games instead of just the The Last of Us code since I can't redeem that until I get onto PSN.
