For Those of you with 90k/2002 With comcast &PS4 ( Solved )

For months i've had problems with 90K error that would swiftly kick me to 2002. That among tons of lag spikes. It made the game simply unplayble. I felt like i wasted money. Which technically i did. because i paid for 6 month and was unable to play for 5 of them. I stumbled across this solution by complete mistake. Now this MAY not fix the problem for everyone but this fixed all my issues with FF14 90K's and overall PS4 Internet connectivity. Below is the video that walked me through step by step and when i was done, i had no more spikes, i had no more lag, i had no more 90K/2002 save for the current DDOS attacks. But beyond that i've been playing with not a single problem. I've watched people not really try to help others that suffer from this problem. Simply because it doesn't affect them. So now that i got my problem fixed I hope it works for you guys as well

Good luck everyone

P.S. Again this may not work for you but it worked for me.

If I remember right, WPA2-AES is one of the better ones for the newer Wireless-N models--better encryption, with minimal impact on performance for the trade-off provided it has a decent chipset. Older models though may choke on it--it's worth testing though, especially if there is sensitive data moving over your wireless.

Other things to look at that often get overlooked are the channel number, the width of the channels (20/40/80Mhz), Band selection (2.4GHz or 5GHz, disable the unused bands to avoid mixed-mode compatibility that can slow things down), and the radio power settings.

Mileage can very, but in theory you can increase you chances of faster transfer rates on your local network simply by tweaking the primary band (2.4/5GHz, no B/G allowed, etc) and the width of each channel--more noticeable with the higher end dual-channel models (n-900, Wireless-AC, etc.). Sometimes the auto channel select doesn't work out so hot... conditions can change at the drop of a hat and the router doesn't switch the channel on the fly. So it may be worth scanning/testing some alternate channels on your own.

Repositioning the router/antennae can make some differences too if you aren't registering high transfer rates locally. I've found that often the power settings for the antennas are set low by default as well. Bumping them a little can sometimes nab you the extra couple decibels you need for a cleaner lock--just be aware that doing so may cause the router to generate more heat, so you'll want to keep an eye on it for a while to make sure it doesn't cause any problems.

Thanks for the feedback Raist.
