urgent !!! help plz ... rb1100hx2 fix huge random packet loss !!!

i’m ready to pull what little hair i have left … plz help me to fix this seemingly huge consistent packet loss i am having on my rb1100hx2 … pls advise what info you need from me to help fix this " issue" i seem to be having a lot of consistent packet loss on my router lately … it gets so bad my voip and even skype drops calls, websites load slow, timeout, our websites load slow etc…

to restate … running ping program on a puter connected directly to modem we get no packet loss …but when connected TO the router we get consistent packet loss in a somewhat random sequence… aka … 10 good pings… then 2 or 3 timeouts then 12 good pings then 5 timeout etc…doesnt seem to be a pattern .. random …

i am wondering is there is a setting we can tweak etc … some have mentioned adjusting ttl … dont know how … pls help :frowning: i initially "contacted our isp thinking it was " their " network … i ran a ping monitor program and it showed packet loss on the public / upstream side of the modem … ( aka plugin computer directly to modem port / plugin ) which they seem to have fixed … but the same program now shows massive packet loss from my laptop thru the router … when i run ping test from " terminal " in mikrotik control panel it shows packet loss in a random pattern… any suggestions …

i have a couple servers behind the router on internal ips, i have 3 public ips provided by my isp … i am using NAT… the problem, we barely even come close to utilizing our pipeline…
the packet loss seems to come in spurts… some have mentioned it might be a ttl issue ..not sure… all i know is that packet loss gets so bad that websites timeout, website pages
i am kinda new to this … i am a computer tech but this mikrotik os is not my area of expertise and know just enuf to get my self in trouble so need some advice and/or diagnosis from experts in router os configuration..

Have you checked the obvious? Replaced any cables, checked power supply, any switches involved?
Also, Do you have any queues setup that may be miss configured?

i’m open to any suggestions right now, i’m assuming you mean the network cables, they are all newly upgraded cat6 cables, i only have one switch between the rb1100 and my laptop but i will check that too… i will try pinging direct from rb1100 port directly … i get same error , i have checked the que as you suggested see the pic attached … that is the only tab with info on it … nothing on simple ques …

What firmware are you on? Have you tried upgrading to 6.28?
