Ok so short bit of background as to how i found out about this. Yesterday early am my time i was getting worse lag than i ever got before pw constantly no amount of rebooting helped router comp etc normally this fixes it for a while. So i ping my router that i know is bad/going bad after a fresh reboot. I was getting ping times in the 6 to 20ms range for a few minutes now this is my router in my house i should get maybe 1ms at most. Then i get a jump to 1200ms again remember this is my router/ap. So i type iwconfig in my terminal window and sure enough spot the problem power managaement:on. I google high ping times to ap linux ubuntu and first topic as i suspected sudo iwconfig wlan0 power off . Im still getting the pings in the 1200ms range to my router at this point. I typ thecommand and from 1200mx max to 750 800 min to 2ish ms max sub 1ms to router. Now i log in to ryzom and my ping times in game are sub 400ms on average normally 210ms or less. During last nights dreaded ow hour my ping times never really went up instead i just got PW box lots of packet loss fs lost (what is going on behind the scenes of the PW connection box) then back to normal for a few minuts then hit again and back to normal went on for maybe half a hour.

So to fix lag on linux any version type
iwconfig to get your cards name

results will look like this

wlp1s0 IEEE 802.11abgn ESSID:"apnameremoved"
Mode:Managed Frequency:2.412 GHz Access Point: g0:48:9g:29:85:Ag
Bit Rate=115.6 Mb/s Tx-Power=22 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:on

In my case my card is named wlp1so so the command will look like this

sudo iwconfig wlp1s0 power off

Again type iwconfig

new reults will look like this

wlp1s0 IEEE 802.11abgn ESSID:"apnameremoved"
Mode:Managed Frequency:2.412 GHz Access Point: g0:48:gA:29:g5:Ag
Bit Rate=115.6 Mb/s Tx-Power=22 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:off

Wave by by to your lag if pwm is your issue as it was mine and many others who have already done the same in game.

Current ping ties in game for me 180ms to 250ms down from 600ms to 750ms average.

As i am by no means a linux guru if any one knows any other tips that reduce lag please drop a post here.
