The lag is at the very start and this is NOT ISP related.
This is clearly something lagging you from your LAN.
Dont be so sure about nothing leeching your LAN.
Im not a noob on these matters and I busted myself a few times with something really silly causing trouble while I was SURE everything was ok.
Verify step by step to be 100% sure youre not fooled by some little bastard.
I understand you are on DSL and your router has an integrated modem in it.
(keep looking how WAN LED behaves)
1. set wifi = OFF.
2. unplug everything from lan.
3. get a PC/laptop from another working network and try it over your lan.
4. run tracert from that pc/laptop again.
3alt. If you dont have anybody that would come and try your lan another way is to reinstall windows on one of your computers without network plugged in and try tracert from that PC.
I can bet my ass off if u do these steps and have a 'clean' PC the lag will be gone.
EDIT: Why do I know its not ISP ? If the lag is persent on the first gateway it is almost impossible that this gateway lags.
Usually the first gateway has not very much to do compared to later larger gateways and has a lot of free resources as it only manages 'local' clients around the place where you live
