have an aprtment with thick walls , my E3500-n750 linksys dsnt work well , which is the best router for range thru thick walls

Solution
That router you have is going to do about the same as all the rest. It pretty modern and all the manufactures know the optimum antenna designs and pretty much all use the same chips inside.
Obviously you do not want to use the 5g band since that is blocked even more by the walls.

There is little you can do even if you would try tricky stuff like direction antenna walls that block signal tend to be able to block most that increase.

You are going to have to find another technology. Things like powerline networks are what most people try next. If you have coax cable you maybe able to use MoCA. And then when nothing else works as stated above you run ethernet cables though the wall.
