Right now I have a very very bad wireless router don't even remember the name, I have problems with connectivity and signal. The problem that I have in my house is that from the place where I have my network stuff to my room I have a couple of walls besides a long distance.
1. Is it ok the assumption that dual band will give me a better range through walls, besides a better range?
2. Which of the routers that I mentioned is better?
3. Could you suggest me a better router besides the 2 routers that I mentioned above?
