Topic: NW-31374-8 and IP Fragmentation Errors

@Wanderingbullet:The issue seems to be fixed for me i had an email from Sony management asking for more info on my isp like if they had blocked certain addresses and other things,in other words they where still believing it could be isp based even though i'd told them it was happening on several different isp's,anyway i've done about 30 tests and not one sign of the ip fragmentation message so looks like todays maintenance may have actually fixed it ,i phoned Sony saying i'd had an email requesting info on my isp gave them my reference number so they could look at my previous calls and said it looks like the maintenance had fixed the issue so it looks like it was indeed there end not our isp's,i also said so now they can hopefully look at what the engineers did see what the problem was and how they fixed it for future reference,anyway hope it's resolved your's and everyone elses issues

@Pixelnme: Same here. Tried my connection a couple of times yesterday and then again today - didn't get the IP Fragment errors so far. Thanks.

Unfortunately im still having this issue since february. Brand new modem and the expensive nighthawk router. Called comcast and they said it wasnt on their end. Im assuming its a ps problem still. Will call sony on monday

I tested my connection a couple of times earlier and the error didn't appear.

Hey guys, I got a new Virgin Media modem/router and the PS4 started giving me the IP packet fragmentation warning.
So I unticked the block fragmented packets option in the router and set the MTU size to 1500. Rebooted the router and then checked the PS4 network settings: all good, no warnings and fast as hell (wired connection). Hope this helps anyone still stuck with this.
